I would definitely love any invention that would eliminate lag and improve throttle response because this is the main issue I have with turbo cars, that and the engine noise, but I'll settle for just improved response 😀

Yeah. It's essentially an electric supercharger and generator powered by exhaust gases. Stresses the engine less than a supercharger and can assist the alternator.
Combine it with a hybrid system, and you could keep the thing at full boost literally 100% of the time while in race mode, and in eco mode, it could keep the compressor off and utilize some of the exhaust gas energy to drive the hybrid system slightly more efficiently
@@ayoutubechannel921 which is the dumbest thing ever. Hybrid racecars, specifically F1 cars are at the cutting edge of engine technology. Fuck the dinosaur V10’s. I’d rather see a tiny 1000hp+ 4 pot hybrid PU.
Feel it's worth mentioning as this is a Porsche video. Porsches anti lag doesn't work the way you described, they leave the intake slightly open when you lift off throttle to keep the turbos spinning
Leaving the intake open does not keep the turbo spinning fast enough to create boost. The lack of spinning of the turbo is due to a lack of exhaust gas energy. Leaving the intake open does not keep the boost going.
@@andrewday3206 In a Porsche with Dynamic Boost, lifting off the throttle pedal shuts off the fuel injectors, but leaves the throttle partially open. This allows more air to pass through the engine, keeping exhaust flowing and spinning the turbos even during deceleration. Dynamic Boost doesn't get rid of turbo lag entirely, but it reduces the time it takes to get the turbochargers spooled up significantly

@@NicoBiturbo All of the current F1 cars have a similar turbocharger integrated with an electric motor-generator. Mercedes' is the one that works best.
I'm pretty sure aswell, cool and hot side split on the opposite sides of the engine with a axle going through and a generator/motor on the cool side if i recall correctly.

I like the concept. The fact that the comp and turbine are electricity separated. Means extra battery's & capacitors could be utilized to spool the compressor instantly . before the exhaust catches up.
I believe a wastegate will no longer needed as if the car has a 48 volt system, the excessive power from the turbi-generator would be just transfered to the battery.
really happy to see road cars finally building on top of the genius that was pioneered by the mercedes F1 team with their electric turbo setup. Disconnecting the shaft brings it to the next level.
Wonder if this could/is also used to increase fuel efficiency. The compressor side of the turbo could be activated upon full opening of the throttle, such that during partial load the turbo isn’t forcing air through a partially opened throttle valve, which normally leads to increased pumping losses. The gas pedal then becomes sort of a pressure regulator for the intake, with the computers regulating throttle position and turbo activation; more gas = more intake pressure.
I think this video miss represents the fundamentals of Porsche's design. This is not a turbocharger it is a power recovery turbine paired with a electrically driven centrifugal supercharger effectively a turbo compound engine. This engine will ultimately be paired with a hybrid powertrain to make use of the power generated by the turbines. Similar in concept to the 1950s aircraft engine the wright R3350 turbo compound except it replaces the fluid couplings with a generator and a mechanical supercharger for a electric one. This concept could potentially double the thermal efficiency of the engine.
@Alfred Wedmore I don't know that about the Titanic that's really cool to know. This Porsche design is not to dissimilar to current F1 engines except in F1 they have the turbine and compressor on the same shaft with the electric motor either in the middle or on a extended compressor shaft. Mercedes is claiming 57% efficiency the best a NA engine can do is like 25% a turbocharged engine can get up to 35%.
it would make sense to use it in a 48V hybrid system. you could always regenerate more electric energy from the exhaust gases. so, if you have more energy in the battery, you can use more of that directly with a motor/generator on the drive train.
Years ago, a man put a small pre-turbo before his big turbo. The NSX he put it on was insane fast... big turbo fast. The key however, was the pre-turbo that removed all turbo lag. Since the small turbo spun up super fast, it fed the needed pressure to the big turbo that eliminated pretty much all lag. It was amazing...
@@yofolkdem1256 no, that’s just another name for twin turbo… well, technically it is two turbos, but they are in series rather than parallel. They are also different sizes.
A danish company did an electric bolt on compressor that you could fit to almost any car 20 years ago. It was a modest boost of maybe 10 - 15% more power, but considering how much better batteries and electric motors have gotten, it must be possible to make a system like this work better than any normal turbo or compressor today.
I thought a decade back this would have been very common at this point from aftermarket turbo manufacturers, yet there still isn't a valid one out for sale.
Easier to just use an engine driven supercharger or an exhaust driven turbo, electric turbos as you describe them just don't have any real advantage to make them a viable product, which is not to say the Porsche type in the video wont work but that's a totally different beast to the old electric turbos.
@@popuptoaster what is different now is battery technology allows you to power way more with the turbine. Batteries can load and discharge faster and most of these systems will run at 48v to start. Formula 1 MGU-h systems run at 800 volts and they can contribute 160+ hp.
New Volvo T8 power train used something similar, use the regen electricity to power the electric turbo. But that system may be more energy saving driving but not performance enhance driving.
Porsche should do this as well. Use the exhaust energy recovery to eliminate the alternator completely. Less rotating mass. Less parasitic drag on the engine.
No such thing as an electric turbo. It's an electric supercharger. You wouldn't say electric exhaust, and electric turbo is open the same tier of wrongness
Probably not since it won't produce enough energy at idle. That said mild hybrid systems use the the electric motor as both the starter and the alternator as well.
@Eternal Peace You're missing half of the electric turbo the way Porsche is pattenting it. There's both a cold side and a hot side turbine. The hot side charges a battery, the cold side uses the battery charge. The difference is that an alternator runs off the drive train and the hot side electric turbo turbine runs off exhaust pressure. The thing being that at idle speeds, there's very little exhaust pressure, but there is plenty of power going through the drive train. So that's where the alternator is a much simpler design to keep your battery charged.
@Eternal Peace I would say yes. Those problems can be easily solved by including a minimally sized 48v battery. When idling too long car can increase idle RPM to build up exhaust gases to start turning the generator to charge up the 48v battery.
Yes, this isn't new technology. Mercedes, Honda Ferrari and Renault have used a system like this for a long time in F1. This was beginning of turbo hybrid regulations, which came into affect in 2014.
I've thought about this. It would require a lot of additional weight for the electrical system. Generator + electric motor + wiring etc adds up when you're trying to keep weight as low as possible

The only time compounding is beneficial is if you need higher pressure ratios. Since most production vehicles are going to be knock limited from the fuel they are running, It makes no sense to try and increase the pressure ratio further through compounding. A properly sized single will do all you can out of the fuel that manufactures design their cars around.
@@ayoutubechannel921 right because you can take advantage of the higher pressure ratios. It’s not practical though because higher pressure ratios are used to increase power and torque so you would do that in 2 applications from the factory. Towing, or a sports car. Problems would be for towing you’d either have a tiny motor with a lot of boost causing which isn’t great for towing because high stress and no torque. Or a huge motor making 2000lb ft which is unnecessary and would incite extra cost for no practical payout. Or in the case of a sports car who wants a massive heavy slug way over the nose of the car and gas is just more fun for that application. So there’s no practical common application where compounding would be worth it in an OE vehicle situation
@@Vehicular.Shenanigans You're misinterpreting what Kenny Phillips meant by turbocompounding. He didn't mean compound turbochargers for higher boost pressure. He meant an extra turbine in the exhaust to recover power and feed it to the crankshaft.
I don't see how it can possibly work without some form of electrical storage system, which might be batteries or, just possibly, a supercapacitor. At low RPM, the generator turbo simply won't produce enough power, so there will have to be some storage facility. However, the prime benefit to me would appear to be packaging and plumbing as the exhaust driven turbine/generator doesn't need to be anywhere near the centrifugal compressor, which is powered by an electric motor. However, it is going to need an electric generator powered by a very hot exhaust turbine, and it might be that oil supplies will have to be arranged to both. In any event, we have cars, like some models of the Land Rover Defender, that have those supplementary electric turbos which do seem to work using a 48V supply. That is rated at 7 kW, but it only has to fill the gap until the turbo spins up, and not the full airflow at maximum RPM. With the Porsche design, the electric supercharger will have to be able to feed the engine at full airflow, and that will mean it's going to have to be a lot more powerful. With mechanically driven superchargers, they can absorb tens of kW at full power, and I guess an electric motor driven one will need power approaching that. We'll see if this turns into anything. In any event, this system could be characterised as an energy recovery system from the exhaust gasses which just happens to drive an electric supercharger.
I loved the oversized aftermarket turbo on my old 87 Buick gn. Gives you a chance to see the other guy smile while you wait for the spool up and blow by. Miss that car
It could work if they made a V4, like in several racing motorcycles. Great sound, and it would be a nice rival for Porsche's turbo flat-4 in the Boxster. Sadly, it'll just be an inline 4 i guess.
just waiting for the Porsche 911 EV SUV xD i mean can Ford sell the fucking disgrace of an object they call mustang Mach-E i mean porsche could certainly pull that off.
It is called adiabatic heating and cooling. When a gas undergoes a pressure increase it heats up only during the change of pressure. It also works inversely where a gas will cool when decreasing in pressure. (frost on a CO2 cartridge when gas is released) FYI it is very relatable to our weather systems and why Santa Ana winds are hot (High pressure compression)
What if you attach an electric motor to a normal turbo so that it could spool the turbo with electricity reducing turbo lag and act as an alternator producing electricity at higher rpms limiting the boost instead of using wastegates

That sort of split turbo on a hybrid would be quite interesting. The battery pack would put boost on tap while giving you the ability to still drive if you become so boost drunk drunk you empty the ev keg since you would still have the ICE (internal combustion engine) to get by.
Decent idea, it will be interesting if the parasitic losses from running 2 turbine/alternator and compressor/motor setups. I wonder if this will be worth it or just marginal gains
The BMW twinpower turbo seems to be pretty reliable and fairly lag free and its been around a while, using a motor to spin up a turbo seems a route to unreliability given the heat around any turbo ?
For me, the best combustion engine is a naturally aspirated petrol 3.0 I6 with 360 PS at 8300 rpm and 312 Nm at 7500 rpm (just like Honda S2000 but with two more cylinders). That combines everything I like - enough power and torque, small size, light weight, wonderful sound, low complexity, easy maintenance, good fuel economy, etc. Imagine a RWD 1200 kg family hatchback with that inside. Sweeeeeeeeeeeeeeeeeeeeeeeeet! ❤
@@djdrastic1 Not exactly. That engine was bigger, had more torque but both power and torque peaked lower down the rev range. But it is somewhat close...
4:05 oh! I read a reference to Audi introducing electric turbos in a car magazine years ago. The magazine was talking about near future innovations but didn't go into a lot of detail. I understood they were talking about eliminating lag by borrowing battery charge to run the compressor then paying it back a second later from an exhaust powered generator. Effectively I assumed the industry was doing exactly what this video says Porsche have developed. The benefits of splitting the hot and cold side didn't even occur to me, I just thought that's what everyone would do with wholly electric compressors. How does an electronically assisted one work then? Must have some kind of mini clutch for the motor, and I suppose that could engage at relatively low RPM because the electric bit is to get it going early.
Nice video and good explanations on how turbos work . Would love to see a video explaining the Turbo in Porsche Taycan Turbo S 😂 what a maketing stunt/joke that was
What a lot of car people seem to misunderstand about turbo chargers is that they dont just allow more fuel to be burned due to more air being forced in, but that the combustion efficiency also goes up with higher pressures. You literally get more energy out of the same amount of fuel.
So Porsche is using a turbine impeller to drive a generator, and using its power to drive a boost impeller which pretty much makes it an electrically driven supercharger. When you are no longer using exhaust gas to spin the turbo, it's more of a supercharger than a turbocharger.
But superchargers are mechanically driven, so this system wouldn't fit the definition of a supercharger either. I would say it's closer to a turbocharger since it uses exhaust gasses as a power source.
@@xIcarus227 Considering they're separate components, you have an electric turbo and an exhaust pressure driven turbine generator. Only if they are an entirely separate electric system, you could consider them as a single entity. I don't think that makes a lot of sense, considering how much electrification there is in modern cars. I'd expect this type of set up to be intended to integrate well with (mild) hybrid systems.
@Alfred Wedmore Do traditional turbochargers have any control benefit over superchargers? I understand electric driven turbochargers to be fully controllable, but a traditional turbo's speed and therefore pressure generation is directly related to exhaust pressures, isn't it?

Fun fact : I've though about this a couple of months ago, when I learned about koegnissegg's electric valves, and i was like, what if we could spool up a turbo electrically using a motor and timed it up and shii... If only i was old/skilled enough to have tried to create this.. Welp porche has beaten me 🙁and who knows what if it would actually worked and i would have been rolling in money bruh. Edit: Grammar mistake
Its been an idea thrown around for a while, Mercedes has already implemented something similar in some of their cars, I believe Audi and VW also have tried it in some capacity aswell.
@@nordvestgaming1238 Interesting, perhaps someone can take it further now that porche and make it a possible widespread thing, with a turbo that spool up insanely fast.
Dude this is Mercedes tech, their F1 tech actually, and actually the new C63 will use the 4 cylinder with the electric turbocharger and will also be a hybrid.....Porsche didn't come up with this
Porsche had been one of the pioneers of electric hybrid vehicles since Lohner-Porsche arrived and supercharge technology for a very long time. The Pre WW2 Auto Unions GP cars (P-Wagen) come to mind , and prior to that the 1929 Mercedes SSK , Porsche’s last car designed before forming his own company..

HVAC fluid returning from the cabin or dedicated loop could be used in an intercooler/ heat exchanger, I really like the idea of an electric boost motor perhaps powered with capacitors that disengages with regeneration and trickle charges once the engine exhaust takes over.
well, actually the turbo is the turbine side and the other side is a compressor, impellers are use for propulsion, that would be the compression side, as is driven with inner energy out to the working fluid
Not a new idea. Hybrid electric turbos have been around for ages, and variants like electric augmented turbos with waste heat recovery far more advanced than the application proposed here have been used in F1 for 8 years now. F1 is now actually stopping use of this technology. Mercedes and Audi have dabbled, several dedicated turbo manufacturers have solutions. Porsche didn't invent it, they would only patent their specific application.
It often surprises me what can be patented. As if electric airpumps didn´t exist prior: Porsche merely combines existing technology, like adding a timer to a coffeemaker.
Hi, I was just wondering, how do you guys handle the royalties? I mean, where do you find and how do you showcase this footage? Do you pay the brands? Thank you!
I was thinking the same initially, but it's still primarily drawing it's power from the exhaust gases rather than the crankshaft. It's just that by converting that energy to electricity rather than directly driving the compressor fan with a shaft they have more flexibility in how/when to drive the compressor.
Funny how Saab solved the lag problem nearly two decades ago when upgrading and refining their Trionic 7 engine management system and the B2x5E/L/R series engines. While the 9-3 had been already moved on to fully GM parts bin based model down to the engine in 2004, the OG9-5 was made with Saabs own parts and systems, along side its Opelified cousin until early 2010. There is no driver discernable lag or delay in response with these cars. And while they were at it, they deemed it more economical to simply control the power output of the B235 engine with software and remove all mechanical and parts differences from its manufacture as this made per unit cots drop significantly simplifying both final assembly and the engine plant production. The only difference is the ECU mapping for a different power and torque output, lesser models being lesser. But with the torque peak appropriately positioned towards low-mid range of the engines power band. These engines use the mentioned "anti-lag" functionality of burning fuel in the exhaust for pre-boosting and are capable of adjusting ignition and fuel injection rate at speeds most engine management and fuel injection systems cannot achieve. This is in part down to Trionic 5.5 and later systems using direct ignition exclusively. But more to the point the system is able to pre-empt the need for accel with gas pedal movement rate being a factor in the calculations. Nothing spectacular today in executive saloons or sports cars, but something literally no-one else was doing in the family car segment in 2006 - 10. As a result when it was very likely GM would be selling Saab off, what they did was release the Aero engines map as a free upgrade to any owner of MY2006 or later 9-5 2.3t or 2.3T who was willing to pop down to their local dealer for 30-45min to have it reflashed. And this would not change warranty liability from Saab or GM anywhere, as the engines didn't have mechanical differences. Most enthusiast had been aware of this at this point for years, and had been doing the modification on their own, or with aid of a dealer which would retain the factory warranty. Not sure how many bothered, but the "LPT" version (which, prior to this MY2006 wasn't given an intercooler and used a ECU with out a knock sensor and some other refinements) was configured to a rather pedestrian 185bhp@5500 and 280Nm@1800 . The Aero punches out 260Bhp@5300 and 370Nm@1900rpm, which is quite an upgrade. The 2.0t was similarly homogenized in manufacture and engine optimization taken to its peak but as it's demand had dropped radically they didn't bother with offering it with more than one power output after 2006 and all 2.0t BioPower B205L's make more than the previous turbocharged 2.0t and 2.0T B204L/R and B205E/L/R before it. The consummate revision received the latest and feature full revision of the Trionic 7 system including both intercooling and knock sensing as standard from MY2005 onwards and the final revision of the B205E (2.0t BioPower) makes 178bhp@5500 and 280Nm@1800. These upgrades also included E85 FlexFuel functionality, which was another motivation for further optimizing their mechanicals and use of the Trionic 7 in all models. Yet again increasing power output with negligible fuel consumption due to ethanol having less energy density, but lower emissions as it burns cleaner. The Trionic Engine Management system was further developed in the GM based engines into the Trionic 8, which in the NG9-5 meant that all engines regardless of displacement from the 1.6l inline 4 to the 2.8l V6 had parallel turbocharging with variable geometry turbos as a main feature. The T8 and it's capabilities were about the only thing GM retained and later utilized after sale of the company to Spyker and the IP and manufacturing licenses for the older bits to China. Funny how Cadillacs and Buicks started to appear with parallel turbos in their four and 6 cyl models not long after the sale. :D VNT/VGT turbocharges are another way solve the issue of lower end torque needing a quick spool up (but less boost) and high-end power more pressure than a smaller turbo can give, making a "LPT" model a pointless concept today. Practically no manufacturer is using a single mode turbo these, as a average sized VNT/VGT turbo solves the issue in all reasonable use applications that the average driver could have for his car. When you factor all those little refinements together, direct ignition, pre-boosting, fast enough and dynamic enough of an ECU with a modern VNT/VGT turbo and a competent engine tuner that knows the design and its flow characteristics well, you get all the benefits with zero lag. And zero down side. The issue has been solved. Decades ago. Some manufacturers just are simply not up to the job. As can be seen from their need to both cheat emissions and use less effective and more expensive means to meet emissions standards. Using nonsense like EGRs etc. that are known to cut service life and increase unreliability after only a couple of years of running. And so they prefer to only install the necessary kit for doing it like real men in high-performance versions of their models. And as they are more interested in an arms race over maximum nominal power output, and in this top trumps for the dealership sales reps, "winning" necessitates leaning hard towards maximizing power while compromising efficiency and reliability and emissions and lends itself to using far more complex solutions for very little overall gain. Certainly zero gain in any public traffic use, even on the autobahns. This means using both a complex sequential turbo system with modern VNT/VGT turbos which are boosted beyond their original reliable design parameters and into Aerospace Mean Time Before Failure and parts refit and replacement cycles. Which is pointless, since this means turbos become disposable or need a complete rebuild after around 150 000 km. Maximum power and high boost pressure in the inlet manifold are not inherent values! Increased thermal efficiency with the worship of stoichiometric burn being observed are! No exceptions! Unfortunately the buyers don't share the sentiment and feel like they want to pay for the privilege of soliciting a turbocharger refit and OEM replacement reseller every 2,5 years and paying 850 - 1500e a pop for running the peak of German automotive engineering in 2020. It's sad that efficiency would be about to start selling cars properly, as governments go "green" and start introducing ever higher environmental protection taxes on fuels and making threats of banning internal combustion engines altogether. First their manufacture. Then all of them from public use. Yes, it will be a criminal offence to drive even a museum vehicle with internal combustion by 2050. Period. This is justifiably so as the industry has forsaken the creed of the engineers, and deserve to die for their disgrace. And the they've only themselves to blame for causing the outrage of users and feeding the politicians revelling to pull the trigger and moralists screaming for their public execution! The internal combustion engine is thus dead, only when it was about to get really good. At not wasting an atom of fuel. We could cut emissions and fuel consumption by 50% over night with what Saab and Köenigsegg have already done and made mass manufacturable. But the company management is now all of a sudden scared of "reputation damage" and of being actually held criminally liable for their negligence! That's why every manufacturer is going electric. Because they're not up to the job of a real engineer! And the only one which was, is already dead. :D The Saab H-engine is still developed and manufactured in China and Algeria but that's a story for another day. Bro-tip to anyone interested or struggling with old Saabs; the Algerians have the entire back catalogue on offer for about 1/10 of what the new-old stock that's in the Saab Parts AB catalogue is going for. I don't think oil pans or steel head gaskets are worth 300e on a rust bucket that's barely worth that much when fully functional.
New for production but not new in general. We made an electric turbo in 2013 and there is even a kit you can but that is an electric turbo. Another design was that using the exhaust to a turbo housing but instead for boost, it would spin basically an alternator that helped give power to the batter/car for the electric turbo.
No way....and this electric turbo, Porsche didn't invent it..... Mercedes did and will be the first to put in production in the new C63.....the new gen AMG will probably all be hybrids with F1 tech....no other manufacturer is doing this
I was thinking it was a dumb idea because generators and motors are not 100% efficient like a straight shaft is, but with the battery in the illustration I’m assuming it’s charging the battery all the time and only using it when boost is needed, also might be a more efficient way to charge a hybrid battery.
I actually like a car with turbo lag. It gives it character, you have to think more, plan and drive it. Turbo lag is foreplay Having power there, easily any time is just boring and takes away the driver involvement and character of the car
The output heat from compression won’t change. It’s Charles’ Law. Removing a hot side or moving it will only reduce engine compartment heat and to a ‘degree’, ambient intake air. But compression is compression and while electric allows for probably almost instant spool, the heat generated will still need to be cooled. No way around that. In the end it doesn’t matter what drives the comp wheels. Exhaust, belt, motor… just different ways to get the same thing. Hot compressed air
On top of that, technically this would be a supercharger, not a turbo. As it is being mechanically driven (by a motor and a battery.) The fact that they are recharging the battery (at different times) by an exhaust gas turbine is rather tangential to this supercharger making more go-baby-go.
The problem with synthetic fuel is that it takes a massive amount of electricity to produce. Then you've got to store and transport it to whichever country. Porsche are doing this just to satiate their own customer's. This will definitely not be viable as a mass market fuel. Not to mention Governments legislating against ICE powered vehicles. The death knell has sounded for ICE whether we like it or not. The future is BEV. Not Hybrid, Not Hydrogen..
The US alone is likely a large enough market for Porsche to justify investing to keep ice relevant for a couple more decades. The US won't eliminate ice as directly as European countries are.
The issue with BEVs is, not every country can provide enough renewable energy to power them all. Germany, for instance, has some parts where it is windy but cold, some were it is warm (only in summer) and some where none of them is constant. Meaning, the renewable energy generated has to be transported all over Germany. Even if the whole country is provided with renewable energy, each car has to get charged at some time. So, each parking spot or most parking spots have to have a charging station, which is nearly impossible to provide and maintain. If you have a garage, okay easy, but when you live in the city, you are more or less screwed finding a charging spot. Hydrogen on the other hand can easily be implemented in our infrastructure. The petrol stations can provide the hydrogen and most cars can also be transformed into hydrogen cars. However, I think a mixture would at least be a fair solution, some BEV (for daily commuting), some hydrogen (for trucks and long distance) and some synthetic ICEs (for sport cars)
@@yourDecisi0nNew ICE cars will be banned from 2030 in Britain. There are only 14 Hydrogen refuelling stations in the entire country and most manufacturers are walking away from the development of Hydrogen Fuel Cell cars. Mercedes has abandoned it's F Cell venture. Both Toyota and Honda have decided against further development of Hydrogen Fuel Cell cars. JLR are in the same boat. We can only buy 2 Hydrogen Fuel Cell cars here. A Toyota Mirai and a Hyundai Nexo. In total only 16 of these 2 cars where bought and registered in GB in 2021 Vs nearly 191000 BEV cars. Hydrogen is a dead duck as far as the car industry is concerned...
@@Lessenjr I don't think the U.S will have much choice in the near future. It will be seen as a Pariah by the rest of the world if it doesn't do something to cut Green House gas emissions in the short term. Not to mention Porsche doesn't sell Hundreds of Thousands in the US to make a difference. The next Boxster/ Cayman are BEV only. As are the next Macan and Cayenne. Taycan has sold in larger numbers than the 911 in 2021 and it'll only continue to outsell it in the future. The facelift 911 will have a hybrid system and my guess is that the next version will most likely be BEV just like the rest of the range. Sad times definitely, but undoubtedly the future. They hated the Motor car back in the early 1900s and never thought it would catch on. Technology and change is a constant. Who knows what will happen in 50 years time. Probably mass transit mobility rather than individuals owning their own cars..
Cool, but wouldn't the additional rotating mass of a generator rotor on the exhaust side cause even more lag? That is unless Porsche are planning on supplementing the motor on the compressor side with a boost from a capacitor or battery bank to pre-spin it before the turbine gets up to speed, then using the power generated from that.
I'd say no. Because the generator is making power that is being applied to the electric turbine and would cancel out any losses the generator would cause. I have a feeling the e turbo side of things would be made to hit its max rpm very very quickly.
I'd say it's somewhere in between. Yes the compressor is direct drive like a supercharger but that power does still come from a turbine powered by exhaust gas, although indirectlyvia the electric system. It should give the best of both worlds. No turbo lag but no sapping of low end torque like on a supercharger.
Interesting video but the main advantage of disconnecting the turbine from the compressor isn't being different sizes you can already do that. The main advantages that they can be spun at different speeds. Different sizes would just be a function of that advantage.
I noticed a lot of modern supercars have burning gasses coming out of the exhaust, even with a turbo. If it's still flames while exiting the car it's just wasted fuel and heat. I wonder if there's a way of cooling and extinguishing the flaming gasses, mixing with fresh air, and then reintroducing to the combustion chamber maybe also using a baffle system to remove solid carbon fouling. I think lost heat is the most inefficient part of car design, so if there was a way of taking this exhaust heat and powering a simple steam engine with it, while also cooling the exhaust and reusing unburnt fumes, You could run the alternator on the steam engine/exhaust cooling unit, and save more torque from the engines combustion. That would make everything much more efficient, without adding too many new agey parts to it.
This is in fact clever. And for those not in the know utilizing hot exhaust gases is more efficient than simply using a generator that is belt or gear driven.
You should look at Garrett E turbo on Mercedes Amg in which we have integrated electric motor and generator on to the existing Exhaust run turbo, more efficient than the Porsche patent.
Would you want one of these on your car?? The seem pretty cool! *Don't forget to subscribe!*
I would definitely love any invention that would eliminate lag and improve throttle response because this is the main issue I have with turbo cars, that and the engine noise, but I'll settle for just improved response 😀

Stresses the engine less than a supercharger and can assist the alternator.

Combine it with a hybrid system, and you could keep the thing at full boost literally 100% of the time while in race mode, and in eco mode, it could keep the compressor off and utilize some of the exhaust gas energy to drive the hybrid system slightly more efficiently

Feel it's worth mentioning as this is a Porsche video. Porsches anti lag doesn't work the way you described, they leave the intake slightly open when you lift off throttle to keep the turbos spinning
Yes. It makes the turbo lag predictable and makes it unbelievably fun to carve some corners
If they leave the intake open, does that mean it uses more gas?
Leaving the intake open does not keep the turbo spinning fast enough to create boost. The lack of spinning of the turbo is due to a lack of exhaust gas energy. Leaving the intake open does not keep the boost going.
At least with my 06 cayenne turbo s it holds the revs up as well
(Edit: I am no engineer, solely talking from experience)
@@andrewday3206 In a Porsche with Dynamic Boost, lifting off the throttle pedal shuts off the fuel injectors, but leaves the throttle partially open. This allows more air to pass through the engine, keeping exhaust flowing and spinning the turbos even during deceleration. Dynamic Boost doesn't get rid of turbo lag entirely, but it reduces the time it takes to get the turbochargers spooled up significantly
We should all get behind Porsche for everything they’re doing to keep ICE alive

I came up with this idea 30 years ago and they laughed at me...
And yet here it is and nobody's laughing now...
I like the concept. The fact that the comp and turbine are electricity separated. Means extra battery's & capacitors could be utilized to spool the compressor instantly . before the exhaust catches up.

really happy to see road cars finally building on top of the genius that was pioneered by the mercedes F1 team with their electric turbo setup. Disconnecting the shaft brings it to the next level.
Wonder if this could/is also used to increase fuel efficiency. The compressor side of the turbo could be activated upon full opening of the throttle, such that during partial load the turbo isn’t forcing air through a partially opened throttle valve, which normally leads to increased pumping losses. The gas pedal then becomes sort of a pressure regulator for the intake, with the computers regulating throttle position and turbo activation; more gas = more intake pressure.
Hey, anyone here knows electric motor can make turbine spool at 100K rpm or not?
I think this video miss represents the fundamentals of Porsche's design. This is not a turbocharger it is a power recovery turbine paired with a electrically driven centrifugal supercharger effectively a turbo compound engine. This engine will ultimately be paired with a hybrid powertrain to make use of the power generated by the turbines. Similar in concept to the 1950s aircraft engine the wright R3350 turbo compound except it replaces the fluid couplings with a generator and a mechanical supercharger for a electric one. This concept could potentially double the thermal efficiency of the engine.
"This is not a turbocharger" thank you for not making the internet dumber.
@Alfred Wedmore I don't know that about the Titanic that's really cool to know. This Porsche design is not to dissimilar to current F1 engines except in F1 they have the turbine and compressor on the same shaft with the electric motor either in the middle or on a extended compressor shaft. Mercedes is claiming 57% efficiency the best a NA engine can do is like 25% a turbocharged engine can get up to 35%.
it would make sense to use it in a 48V hybrid system.
you could always regenerate more electric energy from the exhaust gases.
so, if you have more energy in the battery, you can use more of that directly with a motor/generator on the drive train.
Years ago, a man put a small pre-turbo before his big turbo. The NSX he put it on was insane fast... big turbo fast. The key however, was the pre-turbo that removed all turbo lag. Since the small turbo spun up super fast, it fed the needed pressure to the big turbo that eliminated pretty much all lag. It was amazing...
Isn't that also a bi-turbo setup ?
@@yofolkdem1256 no, that’s just another name for twin turbo… well, technically it is two turbos, but they are in series rather than parallel. They are also different sizes.
A danish company did an electric bolt on compressor that you could fit to almost any car 20 years ago. It was a modest boost of maybe 10 - 15% more power, but considering how much better batteries and electric motors have gotten, it must be possible to make a system like this work better than any normal turbo or compressor today.
I thought a decade back this would have been very common at this point from aftermarket turbo manufacturers, yet there still isn't a valid one out for sale.
Easier to just use an engine driven supercharger or an exhaust driven turbo, electric turbos as you describe them just don't have any real advantage to make them a viable product, which is not to say the Porsche type in the video wont work but that's a totally different beast to the old electric turbos.
@@popuptoaster what is different now is battery technology allows you to power way more with the turbine. Batteries can load and discharge faster and most of these systems will run at 48v to start. Formula 1 MGU-h systems run at 800 volts and they can contribute 160+ hp.
Good to see some nice modern tweaks on what will soon be a museum piece.
New Volvo T8 power train used something similar, use the regen electricity to power the electric turbo. But that system may be more energy saving driving but not performance enhance driving.
Porsche should do this as well. Use the exhaust energy recovery to eliminate the alternator completely. Less rotating mass. Less parasitic drag on the engine.
No such thing as an electric turbo. It's an electric supercharger. You wouldn't say electric exhaust, and electric turbo is open the same tier of wrongness
Thing is at this point going a hell of a lot faster is going from 2.7 to 2.6
Could such a turbo remove the need for an alternator? Would this further reduce drag on the drivetrain?
Probably not since it won't produce enough energy at idle. That said mild hybrid systems use the the electric motor as both the starter and the alternator as well.
@@flacjacket Makes sense, so if they all used the same battery/wasn't insanely expensive, could be pretty nice for overall efficiency
@Eternal Peace You're missing half of the electric turbo the way Porsche is pattenting it. There's both a cold side and a hot side turbine. The hot side charges a battery, the cold side uses the battery charge.
The difference is that an alternator runs off the drive train and the hot side electric turbo turbine runs off exhaust pressure. The thing being that at idle speeds, there's very little exhaust pressure, but there is plenty of power going through the drive train. So that's where the alternator is a much simpler design to keep your battery charged.
@Eternal Peace I would say yes. Those problems can be easily solved by including a minimally sized 48v battery. When idling too long car can increase idle RPM to build up exhaust gases to start turning the generator to charge up the 48v battery.
didn't mercedes hpp come up with the split hot cold turbo for the w05 back in '14?
Yes, this isn't new technology. Mercedes, Honda Ferrari and Renault have used a system like this for a long time in F1. This was beginning of turbo hybrid regulations, which came into affect in 2014.
I love the turbo lag - always thought that was a fun part of turbo!

I've thought about this. It would require a lot of additional weight for the electrical system. Generator + electric motor + wiring etc adds up when you're trying to keep weight as low as possible

The only time compounding is beneficial is if you need higher pressure ratios. Since most production vehicles are going to be knock limited from the fuel they are running, It makes no sense to try and increase the pressure ratio further through compounding. A properly sized single will do all you can out of the fuel that manufactures design their cars around.
@@Vehicular.Shenanigans compounding might work on diesels
@@ayoutubechannel921 right because you can take advantage of the higher pressure ratios. It’s not practical though because higher pressure ratios are used to increase power and torque so you would do that in 2 applications from the factory. Towing, or a sports car. Problems would be for towing you’d either have a tiny motor with a lot of boost causing which isn’t great for towing because high stress and no torque. Or a huge motor making 2000lb ft which is unnecessary and would incite extra cost for no practical payout. Or in the case of a sports car who wants a massive heavy slug way over the nose of the car and gas is just more fun for that application. So there’s no practical common application where compounding would be worth it in an OE vehicle situation
@@Vehicular.Shenanigans You're misinterpreting what Kenny Phillips meant by turbocompounding. He didn't mean compound turbochargers for higher boost pressure. He meant an extra turbine in the exhaust to recover power and feed it to the crankshaft.
I used a leaf blower 20 years ago..a bit noisy.
I don't see how it can possibly work without some form of electrical storage system, which might be batteries or, just possibly, a supercapacitor. At low RPM, the generator turbo simply won't produce enough power, so there will have to be some storage facility. However, the prime benefit to me would appear to be packaging and plumbing as the exhaust driven turbine/generator doesn't need to be anywhere near the centrifugal compressor, which is powered by an electric motor. However, it is going to need an electric generator powered by a very hot exhaust turbine, and it might be that oil supplies will have to be arranged to both.
In any event, we have cars, like some models of the Land Rover Defender, that have those supplementary electric turbos which do seem to work using a 48V supply. That is rated at 7 kW, but it only has to fill the gap until the turbo spins up, and not the full airflow at maximum RPM. With the Porsche design, the electric supercharger will have to be able to feed the engine at full airflow, and that will mean it's going to have to be a lot more powerful. With mechanically driven superchargers, they can absorb tens of kW at full power, and I guess an electric motor driven one will need power approaching that. We'll see if this turns into anything.
In any event, this system could be characterised as an energy recovery system from the exhaust gasses which just happens to drive an electric supercharger.
I loved the oversized aftermarket turbo on my old 87 Buick gn. Gives you a chance to see the other guy smile while you wait for the spool up and blow by. Miss that car

Yup, I hoped they'd at least use the inline 6
Even sadder Mercedes completely pulls out of ICEs from 2026 onwards

just waiting for the Porsche 911 EV SUV xD i mean can Ford sell the fucking disgrace of an object they call mustang Mach-E i mean porsche could certainly pull that off.
It is called adiabatic heating and cooling. When a gas undergoes a pressure increase it heats up only during the change of pressure. It also works inversely where a gas will cool when decreasing in pressure. (frost on a CO2 cartridge when gas is released) FYI it is very relatable to our weather systems and why Santa Ana winds are hot (High pressure compression)
What if you attach an electric motor to a normal turbo so that it could spool the turbo with electricity reducing turbo lag and act as an alternator producing electricity at higher rpms limiting the boost instead of using wastegates

Decent idea, it will be interesting if the parasitic losses from running 2 turbine/alternator and compressor/motor setups. I wonder if this will be worth it or just marginal gains
it's powered by exhaust gasses aka waste
@@GewelReal correct! But transferred from thermal, into kinetic, into electric and back.
The BMW twinpower turbo seems to be pretty reliable and fairly lag free and its been around a while, using a motor to spin up a turbo seems a route to unreliability given the heat around any turbo ?
For me, the best combustion engine is a naturally aspirated petrol 3.0 I6 with 360 PS at 8300 rpm and 312 Nm at 7500 rpm (just like Honda S2000 but with two more cylinders). That combines everything I like - enough power and torque, small size, light weight, wonderful sound, low complexity, easy maintenance, good fuel economy, etc. Imagine a RWD 1200 kg family hatchback with that inside. Sweeeeeeeeeeeeeeeeeeeeeeeeet! ❤
You want the M3 CSL engine ?
@@djdrastic1 Not exactly. That engine was bigger, had more torque but both power and torque peaked lower down the rev range. But it is somewhat close...
Can't imagine a better clip to demonstrate turbo sound than the Audi S1 Quattro you showed in the 1985 1000 Lakes Rally. Good choice😊👍
So thats how the new turbo taycan really works 🤔🤔
4:05 oh! I read a reference to Audi introducing electric turbos in a car magazine years ago. The magazine was talking about near future innovations but didn't go into a lot of detail. I understood they were talking about eliminating lag by borrowing battery charge to run the compressor then paying it back a second later from an exhaust powered generator.
Effectively I assumed the industry was doing exactly what this video says Porsche have developed. The benefits of splitting the hot and cold side didn't even occur to me, I just thought that's what everyone would do with wholly electric compressors. How does an electronically assisted one work then? Must have some kind of mini clutch for the motor, and I suppose that could engage at relatively low RPM because the electric bit is to get it going early.
Can you imagine this turbo system combined with electronically actuated intake/exhaust valves.. could be the greatest ICE of all time...
I was thinking the same thing!
It’s still so limited because it’s ICE compared to EV…it’s diminishing returns at this point and the entire industry is going EV 😯
@@chrisvig123 true. Just look at the Porsche Mission R... now there's an EV concept race car to get excited about🙂
Putting money into R&D for ICE engines is a waste at this point. EV is the future.
Nice video and good explanations on how turbos work . Would love to see a video explaining the Turbo in Porsche Taycan Turbo S 😂 what a maketing stunt/joke that was
Germany isn't even ready to give up on coal, no wonder they are holding on hard to gas powered engines :D
What a lot of car people seem to misunderstand about turbo chargers is that they dont just allow more fuel to be burned due to more air being forced in, but that the combustion efficiency also goes up with higher pressures. You literally get more energy out of the same amount of fuel.
So Porsche is using a turbine impeller to drive a generator, and using its power to drive a boost impeller which pretty much makes it an electrically driven supercharger. When you are no longer using exhaust gas to spin the turbo, it's more of a supercharger than a turbocharger.
But superchargers are mechanically driven, so this system wouldn't fit the definition of a supercharger either.
I would say it's closer to a turbocharger since it uses exhaust gasses as a power source.
@@xIcarus227 Considering they're separate components, you have an electric turbo and an exhaust pressure driven turbine generator. Only if they are an entirely separate electric system, you could consider them as a single entity. I don't think that makes a lot of sense, considering how much electrification there is in modern cars. I'd expect this type of set up to be intended to integrate well with (mild) hybrid systems.
@Alfred Wedmore Do traditional turbochargers have any control benefit over superchargers?
I understand electric driven turbochargers to be fully controllable, but a traditional turbo's speed and therefore pressure generation is directly related to exhaust pressures, isn't it?
Would it be possible to use exhaust gas energy recovered to push extra air at idle for really high "lean burn"
Well, Porsche has been testing the upcoming 992.2 Turbo S with a 48-volt system for the past few months...

Excellent presentation. 👍
Fun fact : I've though about this a couple of months ago, when I learned about koegnissegg's electric valves, and i was like, what if we could spool up a turbo electrically using a motor and timed it up and shii...
If only i was old/skilled enough to have tried to create this.. Welp porche has beaten me 🙁and who knows what if it would actually worked and i would have been rolling in money bruh.
Edit: Grammar mistake
Its been an idea thrown around for a while, Mercedes has already implemented something similar in some of their cars, I believe Audi and VW also have tried it in some capacity aswell.
@@delusion2987 i didn't know about that 😶
@@nordvestgaming1238 Interesting, perhaps someone can take it further now that porche and make it a possible widespread thing, with a turbo that spool up insanely fast.

The 6 cylinder could be a v6 turbo hybrid.....if you know, you know
Was thinking this was similar to the split-turbo concept that some F1 cars use
Are you suggesting they could enter F1 with this setup?
Very informative video. Thanks mate.
Dude this is Mercedes tech, their F1 tech actually, and actually the new C63 will use the 4 cylinder with the electric turbocharger and will also be a hybrid.....Porsche didn't come up with this

They are still connected by a shaft, so compressor and turbine speeds are equal. Porsche have the ability to vary this
HVAC fluid returning from the cabin or dedicated loop could be used in an intercooler/ heat exchanger, I really like the idea of an electric boost motor perhaps powered with capacitors that disengages with regeneration and trickle charges once the engine exhaust takes over.
Only one side of the turbo is called an impeller just as a side note.
well, actually the turbo is the turbine side and the other side is a compressor,
impellers are use for propulsion, that would be the compression side,
as is driven with inner energy out to the working fluid
@@Xayuap turbo is the complete unit....Turbine is the driving side....Impeller is the compressing side.
@@catlee8064 almost, a turbo machine can be a compressor or a turbine, so you got two turbomachines in one unit
I recently bought an “air fryer.” It’s called the “Turbo Air.” It makes great French fries & chicken nuggets 👍🏾
Not a new idea. Hybrid electric turbos have been around for ages, and variants like electric augmented turbos with waste heat recovery far more advanced than the application proposed here have been used in F1 for 8 years now. F1 is now actually stopping use of this technology. Mercedes and Audi have dabbled, several dedicated turbo manufacturers have solutions. Porsche didn't invent it, they would only patent their specific application.
It often surprises me what can be patented.
As if electric airpumps didn´t exist prior: Porsche merely combines existing technology, like adding a timer to a coffeemaker.
And it’s because of Porsche and Audi that F1 are going to remove this amazing piece of engineering… such a shame.
Hi, I was just wondering, how do you guys handle the royalties? I mean, where do you find and how do you showcase this footage? Do you pay the brands? Thank you!
An electric turbo is a supercharger. If you use a motor to assist the turbine in combination with the exhaust gas that’s a diffrent story
I was thinking the same initially, but it's still primarily drawing it's power from the exhaust gases rather than the crankshaft. It's just that by converting that energy to electricity rather than directly driving the compressor fan with a shaft they have more flexibility in how/when to drive the compressor.
@@RyanJamesODonnell Ig.
1:42 is that the new outboard engine crankshaft type the 1 manufacturer is trying to keep as a secret?
Funny how Saab solved the lag problem nearly two decades ago when upgrading and refining their Trionic 7 engine management system and the B2x5E/L/R series engines. While the 9-3 had been already moved on to fully GM parts bin based model down to the engine in 2004, the OG9-5 was made with Saabs own parts and systems, along side its Opelified cousin until early 2010. There is no driver discernable lag or delay in response with these cars. And while they were at it, they deemed it more economical to simply control the power output of the B235 engine with software and remove all mechanical and parts differences from its manufacture as this made per unit cots drop significantly simplifying both final assembly and the engine plant production. The only difference is the ECU mapping for a different power and torque output, lesser models being lesser. But with the torque peak appropriately positioned towards low-mid range of the engines power band.
These engines use the mentioned "anti-lag" functionality of burning fuel in the exhaust for pre-boosting and are capable of adjusting ignition and fuel injection rate at speeds most engine management and fuel injection systems cannot achieve. This is in part down to Trionic 5.5 and later systems using direct ignition exclusively. But more to the point the system is able to pre-empt the need for accel with gas pedal movement rate being a factor in the calculations.
Nothing spectacular today in executive saloons or sports cars, but something literally no-one else was doing in the family car segment in 2006 - 10.
As a result when it was very likely GM would be selling Saab off, what they did was release the Aero engines map as a free upgrade to any owner of MY2006 or later 9-5 2.3t or 2.3T who was willing to pop down to their local dealer for 30-45min to have it reflashed. And this would not change warranty liability from Saab or GM anywhere, as the engines didn't have mechanical differences.
Most enthusiast had been aware of this at this point for years, and had been doing the modification on their own, or with aid of a dealer which would retain the factory warranty.
Not sure how many bothered, but the "LPT" version (which, prior to this MY2006 wasn't given an intercooler and used a ECU with out a knock sensor and some other refinements) was configured to a rather pedestrian 185bhp@5500 and 280Nm@1800 . The Aero punches out 260Bhp@5300 and 370Nm@1900rpm, which is quite an upgrade.
The 2.0t was similarly homogenized in manufacture and engine optimization taken to its peak but as it's demand had dropped radically they didn't bother with offering it with more than one power output after 2006 and all 2.0t BioPower B205L's make more than the previous turbocharged 2.0t and 2.0T B204L/R and B205E/L/R before it.
The consummate revision received the latest and feature full revision of the Trionic 7 system including both intercooling and knock sensing as standard from MY2005 onwards and the final revision of the B205E (2.0t BioPower) makes 178bhp@5500 and 280Nm@1800.
These upgrades also included E85 FlexFuel functionality, which was another motivation for further optimizing their mechanicals and use of the Trionic 7 in all models. Yet again increasing power output with negligible fuel consumption due to ethanol having less energy density, but lower emissions as it burns cleaner.
The Trionic Engine Management system was further developed in the GM based engines into the Trionic 8, which in the NG9-5 meant that all engines regardless of displacement from the 1.6l inline 4 to the 2.8l V6 had parallel turbocharging with variable geometry turbos as a main feature. The T8 and it's capabilities were about the only thing GM retained and later utilized after sale of the company to Spyker and the IP and manufacturing licenses for the older bits to China.
Funny how Cadillacs and Buicks started to appear with parallel turbos in their four and 6 cyl models not long after the sale. :D
VNT/VGT turbocharges are another way solve the issue of lower end torque needing a quick spool up (but less boost) and high-end power more pressure than a smaller turbo can give, making a "LPT" model a pointless concept today. Practically no manufacturer is using a single mode turbo these, as a average sized VNT/VGT turbo solves the issue in all reasonable use applications that the average driver could have for his car.
When you factor all those little refinements together, direct ignition, pre-boosting, fast enough and dynamic enough of an ECU with a modern VNT/VGT turbo and a competent engine tuner that knows the design and its flow characteristics well, you get all the benefits with zero lag. And zero down side.
The issue has been solved. Decades ago. Some manufacturers just are simply not up to the job. As can be seen from their need to both cheat emissions and use less effective and more expensive means to meet emissions standards. Using nonsense like EGRs etc. that are known to cut service life and increase unreliability after only a couple of years of running. And so they prefer to only install the necessary kit for doing it like real men in high-performance versions of their models.
And as they are more interested in an arms race over maximum nominal power output, and in this top trumps for the dealership sales reps, "winning" necessitates leaning hard towards maximizing power while compromising efficiency and reliability and emissions and lends itself to using far more complex solutions for very little overall gain. Certainly zero gain in any public traffic use, even on the autobahns.
This means using both a complex sequential turbo system with modern VNT/VGT turbos which are boosted beyond their original reliable design parameters and into Aerospace Mean Time Before Failure and parts refit and replacement cycles. Which is pointless, since this means turbos become disposable or need a complete rebuild after around 150 000 km. Maximum power and high boost pressure in the inlet manifold are not inherent values! Increased thermal efficiency with the worship of stoichiometric burn being observed are!
No exceptions! Unfortunately the buyers don't share the sentiment and feel like they want to pay for the privilege of soliciting a turbocharger refit and OEM replacement reseller every 2,5 years and paying 850 - 1500e a pop for running the peak of German automotive engineering in 2020.
It's sad that efficiency would be about to start selling cars properly, as governments go "green" and start introducing ever higher environmental protection taxes on fuels and making threats of banning internal combustion engines altogether. First their manufacture. Then all of them from public use. Yes, it will be a criminal offence to drive even a museum vehicle with internal combustion by 2050. Period.
This is justifiably so as the industry has forsaken the creed of the engineers, and deserve to die for their disgrace. And the they've only themselves to blame for causing the outrage of users and feeding the politicians revelling to pull the trigger and moralists screaming for their public execution!
The internal combustion engine is thus dead, only when it was about to get really good. At not wasting an atom of fuel. We could cut emissions and fuel consumption by 50% over night with what Saab and Köenigsegg have already done and made mass manufacturable. But the company management is now all of a sudden scared of "reputation damage" and of being actually held criminally liable for their negligence!
That's why every manufacturer is going electric. Because they're not up to the job of a real engineer! And the only one which was, is already dead. :D
The Saab H-engine is still developed and manufactured in China and Algeria but that's a story for another day. Bro-tip to anyone interested or struggling with old Saabs; the Algerians have the entire back catalogue on offer for about 1/10 of what the new-old stock that's in the Saab Parts AB catalogue is going for.
I don't think oil pans or steel head gaskets are worth 300e on a rust bucket that's barely worth that much when fully functional.
New for production but not new in general. We made an electric turbo in 2013 and there is even a kit you can but that is an electric turbo.
Another design was that using the exhaust to a turbo housing but instead for boost, it would spin basically an alternator that helped give power to the batter/car for the electric turbo.
I've really enjoyed getting a turbo car, but my licence hasn't 😍
Hadn’t heard of this, but that’s pretty cool.
If Porsche to enter F1 it is Mercedes' worst nightmare. 🙁
No way....and this electric turbo, Porsche didn't invent it..... Mercedes did and will be the first to put in production in the new C63.....the new gen AMG will probably all be hybrids with F1 tech....no other manufacturer is doing this
I was thinking it was a dumb idea because generators and motors are not 100% efficient like a straight shaft is, but with the battery in the illustration I’m assuming it’s charging the battery all the time and only using it when boost is needed, also might be a more efficient way to charge a hybrid battery.
I actually like a car with turbo lag. It gives it character, you have to think more, plan and drive it.
Turbo lag is foreplay
Having power there, easily any time is just boring and takes away the driver involvement and character of the car
The output heat from compression won’t change. It’s Charles’ Law. Removing a hot side or moving it will only reduce engine compartment heat and to a ‘degree’, ambient intake air. But compression is compression and while electric allows for probably almost instant spool, the heat generated will still need to be cooled. No way around that. In the end it doesn’t matter what drives the comp wheels. Exhaust, belt, motor… just different ways to get the same thing. Hot compressed air
Electric motor driven turbos are not a new idea or technology, or genius
It is the way Porsche is doing it hence getting pattens for it
On top of that, technically this would be a supercharger, not a turbo. As it is being mechanically driven (by a motor and a battery.) The fact that they are recharging the battery (at different times) by an exhaust gas turbine is rather tangential to this supercharger making more go-baby-go.
This isn’t a Chinese eBay electric turbo 🤦🏼♂️
Their engineers must be tenured.
Imagine being an engineer working on improving vinyl records today.
The problem with synthetic fuel is that it takes a massive amount of electricity to produce. Then you've got to store and transport it to whichever country. Porsche are doing this just to satiate their own customer's. This will definitely not be viable as a mass market fuel. Not to mention Governments legislating against ICE powered vehicles. The death knell has sounded for ICE whether we like it or not. The future is BEV. Not Hybrid, Not Hydrogen..
The US alone is likely a large enough market for Porsche to justify investing to keep ice relevant for a couple more decades. The US won't eliminate ice as directly as European countries are.
The issue with BEVs is, not every country can provide enough renewable energy to power them all. Germany, for instance, has some parts where it is windy but cold, some were it is warm (only in summer) and some where none of them is constant. Meaning, the renewable energy generated has to be transported all over Germany. Even if the whole country is provided with renewable energy, each car has to get charged at some time. So, each parking spot or most parking spots have to have a charging station, which is nearly impossible to provide and maintain. If you have a garage, okay easy, but when you live in the city, you are more or less screwed finding a charging spot.
Hydrogen on the other hand can easily be implemented in our infrastructure. The petrol stations can provide the hydrogen and most cars can also be transformed into hydrogen cars. However, I think a mixture would at least be a fair solution, some BEV (for daily commuting), some hydrogen (for trucks and long distance) and some synthetic ICEs (for sport cars)
@@yourDecisi0nNew ICE cars will be banned from 2030 in Britain. There are only 14 Hydrogen refuelling stations in the entire country and most manufacturers are walking away from the development of Hydrogen Fuel Cell cars. Mercedes has abandoned it's F Cell venture. Both Toyota and Honda have decided against further development of Hydrogen Fuel Cell cars. JLR are in the same boat. We can only buy 2 Hydrogen Fuel Cell cars here. A Toyota Mirai and a Hyundai Nexo. In total only 16 of these 2 cars where bought and registered in GB in 2021 Vs nearly 191000 BEV cars. Hydrogen is a dead duck as far as the car industry is concerned...
@@Lessenjr I don't think the U.S will have much choice in the near future. It will be seen as a Pariah by the rest of the world if it doesn't do something to cut Green House gas emissions in the short term. Not to mention Porsche doesn't sell Hundreds of Thousands in the US to make a difference. The next Boxster/ Cayman are BEV only. As are the next Macan and Cayenne. Taycan has sold in larger numbers than the 911 in 2021 and it'll only continue to outsell it in the future. The facelift 911 will have a hybrid system and my guess is that the next version will most likely be BEV just like the rest of the range. Sad times definitely, but undoubtedly the future. They hated the Motor car back in the early 1900s and never thought it would catch on. Technology and change is a constant. Who knows what will happen in 50 years time. Probably mass transit mobility rather than individuals owning their own cars..
@@pauln0371 Your neo communist utopia will never happen, go cry to klaus schwab.
Cool, but wouldn't the additional rotating mass of a generator rotor on the exhaust side cause even more lag? That is unless Porsche are planning on supplementing the motor on the compressor side with a boost from a capacitor or battery bank to pre-spin it before the turbine gets up to speed, then using the power generated from that.
I'd say no. Because the generator is making power that is being applied to the electric turbine and would cancel out any losses the generator would cause. I have a feeling the e turbo side of things would be made to hit its max rpm very very quickly.
Pretty much this is called a supercharger but powered by electric motor
I'd say it's somewhere in between. Yes the compressor is direct drive like a supercharger but that power does still come from a turbine powered by exhaust gas, although indirectlyvia the electric system. It should give the best of both worlds. No turbo lag but no sapping of low end torque like on a supercharger.
@@gerardmontgomery280 well basically have the advantages of a supercharger and a turbo in the same thing

Interesting video but the main advantage of disconnecting the turbine from the compressor isn't being different sizes you can already do that. The main advantages that they can be spun at different speeds. Different sizes would just be a function of that advantage.
Can you not just do that with mechanical gears on normal turbos?
@@PaulMansfield you could but this way you can vary the difference in speed.
@@DoRC good point, and you could also switch the boost between "weekend cruise" and "track" mode.
Great video. Thanks!
I noticed a lot of modern supercars have burning gasses coming out of the exhaust, even with a turbo. If it's still flames while exiting the car it's just wasted fuel and heat. I wonder if there's a way of cooling and extinguishing the flaming gasses, mixing with fresh air, and then reintroducing to the combustion chamber maybe also using a baffle system to remove solid carbon fouling. I think lost heat is the most inefficient part of car design, so if there was a way of taking this exhaust heat and powering a simple steam engine with it, while also cooling the exhaust and reusing unburnt fumes, You could run the alternator on the steam engine/exhaust cooling unit, and save more torque from the engines combustion. That would make everything much more efficient, without adding too many new agey parts to it.
This is in fact clever. And for those not in the know utilizing hot exhaust gases is more efficient than simply using a generator that is belt or gear driven.
true. instead of opening blow off valve or wastegate, electric system can simply store the excess energy into battery or super capacitor.
I subscribed bcz that my love for cars and jets met a mechanical engineer here.!
Small higher boosting engines makes the car more efficient but at the cost of reliability especially in the long run.
"not ready to give up on combustion power..." All i needed to hear, with all do respect for our planet tho ❤️
You should look at Garrett E turbo on Mercedes Amg in which we have integrated electric motor and generator on to the existing Exhaust run turbo, more efficient than the Porsche patent.
