Hydrogen is an awful fuel because: 1. it's not found in nature -- you have to crack methane (so it is a fossil fuel) or perform electrolysis of water (which is inefficient so the overall energy score is low). 2. it may have a high energy density by weight -- but by volume (which is far more important) it has a very low energy density unless you liquify it which requires cryogenic storage which is itself heavy, complex and expensive. If stored as a gas at very high pressure you then have a fantastic bomb in your car because the pressures have to be enormous to get half-decent densities. 3. it is incredibly difficult to store for any length of time (such as at a refuling station or in a car tank for more than a few days) because the H2 molecule is so small that it "leaks" through any containment vessel -- in much the same way as helium quickly leaks out of party balloons. 4. it causes embritlement of steel which means you can't use steel on the pressure side of the fuel system -- it will break after a period of time. There are a number of other reasons why H2 is a lousy fuel but this is why, even with Toyota's huge investment in it, they have failed to create a viable passenger vehicle that has any market-share.
I am still a fan of H but concede that the reality of the fuel is simply not there. Your summary above is perfect. One additional point is that the large Lithium ION battery is also a terrifying thing to be driving around with. They too have a devastating fire when they go. But moving liquid hydrocarbons and electricity are much more controllable delivery methods.
I've over the last year or so seen car youtubers saying that battery electric vehicles are a temporary solution while we wait for hydrogen vehicles which are the future. I don't get it.
I mean a lot of engines are already replacements when they break. Regardless I trust Porsche engineers more than internet opinions, if they think it’s viable then I’ll trust them - they’ve not given any reason to doubt them so far.
the clutch'd turbo was a common practice in the rail industry; low engine speeds, the turbo would be driven by a clutch or belt to effectively be a centrifugal supercharger. at higher engine loads when the exhaust pressure was high enough or the drag from the turbine drive got too high, it would disengage the clutch to act as a normal turbo. in the end it proved to be more complicated than a normal and better designed turbo so everything just uses that now.
Thats not how it works though because the second combustion event takes place before teh first one is exhausted. That means the first event is almost emissions free at the exhaust so you're getting one and a half power strokes for the emissions of one and a 10th. That not only means less emissions per volume but also more power meaning there is less volume needed in the first place.
Toyota tried with hydrogen combustion. They’ve gone some way to solving the problems of the extremely high temperatures hydrogen burns at. However, the size of fuel tanks presents a problem. Hydrogen is extremely energy dense. A kilogram of hydrogen holds loads more energy than a kilogram of petrol. But a kilogram of petrol fits in a litre jug. A kilogram of hydrogen gas takes up a lot of of space, 0.082Kg per cubic metre. It’s like comparing a kilogram of feathers to a kilogram of lead. In the Mirai fuel cell car they compress the hydrogen to 750 bar, 10,000 psi, and fill 3 enormous fuel tanks. It gets about 350 miles range. A Mirai is over 5 meters long with the internal space of a Fiesta because they’re so big. An ICE engine is about half as efficient as a fuel cell so needs tanks twice the size. This means in a small hatchback there would only be room for a drivers seat. To try and improve this Toyota used liquid hydrogen in the Corolla hydrogen ICE race car. Liquid hydrogen is very difficult to store. It has to be kept below its -253 degrees C boiling point. As a consequence it keeps boiling off and very explosive hydrogen gas has to be vented out of the tank. The inevitable happened with the Corolla, it caught fire. Hydrogen is a very difficult gas to store, transport and contain in a tank for use in a car. Car manufacturers have been trying to use it since the 1970s. Oil companies love it because they currently make nearly all of it in very dirty carbon intensive processes. They can keep the business model of making motorists go to fuel stations and charging lots of money for fuel. Hydrogen combustion doesn’t seem to be on the road to being a mainstream fuel.
@@Southghost5997 BMW know all about it when they tried to use hydrogen for ICE cars with the Hydrogen 7 a couple of decades ago. They constantly vented hydrogen gas as the liquid boiled. Couldn’t put them in an enclosed garage- boom.
@@EVinstructor Yep, I remember visiting the BMW booth at the IAA in Frankfurt in the eighties and talked to the guys showing the 750i with hydrogen engine...
Until we can get the electrolysis of water happening efficiently we wont have hydrogen ice, its the only way we get hydrogen ice because im sure im not the only person who doesnt feel comfortable driving around surrounded by hydrogen tanks
Another big problem with combusting hydrogen in a piston engine is NOx emissions, just like with diesel. Then you're not exactly zero emission like everything is transitioning to.
had my ass going cross eyed just watching the video, i know its shitty to say but homie needs to wear sun glasses or something lol its more than a little distracting
It would. Porsche will rely on other manufacturers purchasing the rights to use their design. If Porsche is the only company to use this the number of fuel powered vehicles reduces resulting in fuel prices being increased to make up for the reduced amount of fuel being purchased. Producing petrol for vehicles is a long, expensive process. Why would they continue producing fuel, importing it and then transporting them to fuel stations and storing it if only a fair few need it?
No chance. Won't be too long before most BEVS will be cheaper than ICE vehicles. Look around, more and more EVs on the road, more and more chargers. Peak global ICE sales passed by a few years ago.
@@markwilson2069 yeah but EVs sucks tho, you can check statistics, people have stopped buying so sales are gradually decreasing and it's not reliable or more efficient regular gas car
The 6 stroke Porsche engine looks like a 4 stroke and 2 stroke engine combined. It’d create lots more power but not sure how it’d be more efficient? The 2 stroke part of the cycle would bring down efficiency vs a regular 4 stroke.
They don’t say it’s more efficient, it can make more power and reduce emissions. Reducing emissions has nothing to do with fuel economy it’s about how clean the fuel is burned. (See dieselgate, vw made their diesels more efficient by letting them pollute more.) This system will basically act like an EGR system but instead of sending exhaust back in the intake it does it during the 2 extra strokes, added benefit is you have more power strokes.
If Porsche is indeed intending to put that into a production car it will actually be better. I too am rather sceptical of the concept, but I ain't gonna doubt Porsche if they decide to have a go at it.
0:45 - It's worth noting that Porsche hasn't managed to get the carbon capture working (because it's fundamentally unworkable) so they're just using CO2 from breweries. Which is a standard way of getting CO2.
For me, what makes synthetic fuels so promising isn't the method of getting CO2, it's simply the fact it uses CO2 at all. I've seen some claims that modern small Petrol-Hybrid engines are so clean that they would potentially emit less than is needed in that process. Now obviously, that's marketing speak and so comes with a very large pinch of salt, but that is a massive improvement. Plus there would be no need to adapt cars or fuel stations as an ICE wouldn't notice the difference between dead-dino fuel and synthetic fuel.
@@deaks25 A 100% clean burning engine would put out exactly the same amount of CO2 that it took to make the fuel. If it put out less that would actually be bad, as that would be particulate matter and unburnt fuel. But synthetic fuels will never be more than a marketing gimmick. They require far too much energy to produce.
@@drunkenhobo8020 That's not even remotely true. Synthetic fuels are not simply the reverse of the combustion process, and different cars emit different levels of CO2. If a gallon of synthetic fuel used 500g of CO2 and the car it goes emits less per gallon, that is a carbon negative result (Yes, that number is just an example). And why would they be just a gimmick? ICEs are not going to disappear overnight in 2035 (assuming that deadline even remains), there will still be hundreds of millions of ICEs on the road and will remain so for several decades. Arguably reducing the emissions of ICEs is FAR more important than BEV development. But let me ask you this then; what IS the solution? You've rubbished hydrogen, now you're rubbishing synthetic fuels. BEV technology has it's own massive environmental problems as well when it comes to mining lithium, and the issues around energy density will remain, even with solid-state batteries, never mind the infrastructure and power generation questions that EVs are inexorably linked to. So what do you suggest is the solution? Or should the car just doomed to extinction?
@@deaks25 You clearly don't understand anything about chemistry - yes, synthetic fuels are effectively the reverse of the combustion process. What you said makes absolutely no sense; carbon is a real physical thing, it can't just disappear. You can't end up with less of it after burning it. If it's cleanly burnt, you'll end up with exactly the same amount of CO2 you used to make it. They're a gimmick from oil companies and ICE marques trying to pretend that there's still life in ICE. There isn't. You're telling me all I need to know when you bring up lithium mining. A 50 kWh pack uses 8kg of lithium. It's a tiny proportion. The car it's in will weigh around 1600 kg. Why not focus on the other 99.5% of materials? If you think power generation is a problem for BEVs, just wait until you hear how much energy hydrogen or synthetic fuels would take to produce.

Wow Mat! Never thought I would hear a good technical explanation on CaeWow but, this video was great and did a wonderful job on explaining the new engine developments at Porsche and Ferrari. Well done.
The whole idea of efficiency and a cool sounding engine will never work together. Any sound you hear is a direct result of vibrations which are inefficient. Thats why the most efficient petrol engines dont make much of a sound, but the horribly inefficient naturally aspirated v12s produce the sweet sound of POWERRRR
Not all V12s are like that. Some of this big engines are for luxury cars. I've driven a Toyota Century V12, it was so silent and smooth, it just reminded me of driving a Tesla Model S. Then I also drove a W12 Bentley Continental and it was loud, just like you mentioned. I do think that electric motors and their inverters can sound pretty cool, in race built EVs. Also the Rimac cars.
lol you know that the noise generated by an ICE is like a minuscule fraction of the inefficiency. Thermal and mechanical inefficiency by comparison is much much more severe in ICE.
I'm blown away by how high-tech these engines are getting. we've come a looooong way since the first ICE engine. I always kind of expect that we'll peak at some point, but it seems we're not there yet.
Its going to sound like a normal four stroke at lower rpm so when this is at 1500rpm it will likely sound like a normal one at 1000rpm. Remember there is no exhaust between the combustion events so you're going to have one exhaust pulse per 6 strokes instead of 4.
so many vaccum cars nowadays just so China and India polute 5x as much for everything we dont polute. and while our good leaders and celebritys fly short distance with their private jets and helicopters.
why would it? It still has the oil sump in there so the crank case and camshafts still get oil. My question is when the piston is up, and those holes are exposed to te bottom end, wouldnt the oil find its way inside the holes and after it to the chamber?
You never mentioned the supercharger in the Ferrari at all Matt. Do we assume it works like any old supercharger and totally disconnected from the complexities of the turbo charging system ?And where the hell are they gonna fit that ??.
Everyone is always saying pouting and crying over maintenance issues and how EVs are simpler, when the reality is that Porsche didn’t even need to do this to begin with. They could’ve taken the easy way out and continued to make EVs in the market, but they choose to continue tailoring to the enthusiast and make cars that have a soul. They know car enthusiasts like the rumble and sound of a gasoline engine; the feeling it provides. They choose to push through the regulations that keep getting stricter. It's through R&D that this technology will get better. I may not have the money to buy this, but I'm glad this exists, even though it might be rough around the edges at first. If it's anyone that can perfect automotive technology, it’s Porsche.
When I was training to be a diesel mechanic the professor pointed out that at the most basic level an automobile needs: 1 - a source of stored energy, 2 - means to convert that into kinetic energy, and if you ever want to stop the vehicle 3 - means to convert kinetic energy into something else. Electric vehicles ace two of those points: the motor can be 90+% efficient at converting stored energy into kinetic energy, and regenerative braking reconverts kinetic energy back into stored energy on braking. A good internal combustion engine is closer to 35% efficiency. I know a lot of people are vibration junkies, but objectively motors are superior to engines. Using internal combustion to convert hydrogen into kinetic energy is purely an exercise in wasting energy just so people can hear vibration. But if engine noise is an important thing in your life, that might be a rewarding tradeoff. However, it will be very, very difficult to match the convenience of liquid fuel as a source of portable stored energy. Finding efficient means to convert liquid fuels into electricity might be worth a closer look. If you are aware of efforts to do so, I would love to hear about it.
As the 1980s were to personal computers, I think the present is to transportation. The advances in energy storage, efficiency, and manufacturing are going to move quickly.
@@mtnman1984 Overall, technological advancements never stop fully yes, but you just used your own argument against yourself. As moores law which, claims a constant improvement in semiconductor performance, is currently proven wrong as the processor speed improvements slow down, combustion engines progress has slowed down already long ago when you look at the data. There is always an end to evolution when you are not whilling to change the general approach, and this new proprietary maintanance hell of a machine wont change that fact either.
Not a big fan of EVs but i'm also a number/science buff and a very objective individual. Electric cars are the way to go....Tesla's latest Model Highland Long Range has a claimed autonomy of 705 km...let's say realistically it's more like 550-570 km. It's getting at a point that I can hardly justify not buying one... For now i'll keep my 2 Mercedes but just because in Italy, because of stupid regulation I cannot charge an EV in my underground garage (I live in a residence)!
@@SpaghettiKillahfundamentally people who are buying EVs aren’t doing so because of the love of EV. It’s for practicality. People who love performance ICE love it for the feel of a high revving ICE engine screaming at you while you send it into a corner. EV cannot match that raw aggression.
I love this development in the automotive industry so much. I was never interested in plain 4 cylinder ecobox engines for commuters that don't car. For all I care, those cars can be electric. But experimental sports car and bike engines. Man, that's where it's at. This stuff really fascinated me, really getting into the intricate depths of the technology and its upkeeps
We may not have all cars going EV, but all this help push internal combustion tech forward in an insane way. Fighting for survival is a powerful motivator.
Unbelievable amounts of engineering hours and genius ideas to improve the combustion engine just a little bit more. And then there is the electric motor without all that stuff.
Wow, Porsche is really pushing boundaries with this 6-stroke engine innovation! 🚗💨 Just when it seemed like electric vehicles were taking over, internal combustion is getting a powerful upgrade. Can't wait to see how this impacts performance and efficiency in the future. Go Porsche!
Hydrogen is $36/Kg in the only state in the US that sells it. You can go about 60 miles per Kg in the 182 Hp Toyota Mirai. However, that has a Hydrogen Fuel Cell which is about twice as efficient as a Hydrogen combustion engine. Imagine paying over $1 per mile to fuel your car!
Exactly. I still do not get why people think that anyone will pay twice for the same result. Just for the sound? Even if hydrogen gets cheaper, it will most likely be more expensive than electricity per mile. For anyone who drives mostly medium distances, EVs are the obvious choice today and will be in the future.
@@Jojo-o6o6w More efficient, more power, runs on their own sustainable fuels. I think there's still so much more to the internal combustion engine that hasn't been tapped.
Less efficient than EVs, not more sustainable then EVs, much more costly even than regular fuel, impossible to produce at mass scale. So your conclusion is wrong
Snide and as ignorant as one can get! First of all you know nothing about wealthy people. If you knew anything, you’d know that wealthy people usually don’t even drive. They have personal drivers for that and usually take the back seat because time is money. Ever heard of that? Case in which a future truly autonomous vehicle will be a no brainer. Tesla has so much more going on that the German (and not only) auto industry are still playing catchup. There is a reason after all why Tesla’s market cap is much more than the whole German auto industry combined.
No, because we already went through that transitioning stage (stone to metal), the last time we went from electric to ICE.... you know, like 120 years ago (give or take).
@@origaminefretami3480 Nothing wrong with electric driving pleasure. I dont hate combustion engines but noise. The high noise cars are just a toy who loves to get attraction by noise. This way people strares at you that i dont care. Silence and power is the real pleasure. Plus accesibility.
@@ismetates7235 Thats....as wrong as it can get. Sure there are some people that love attention but a good engine noise pleases the driver the most. Why do Formula 1 drivers like Vettel and Hamilton wanted the V12s back after the Six cylinder Hybrids got introduced? So more people stare at them? Lol. Why do car reviewers love a good sounding engines when they are testing it at a closed road? Because its fun for the driver.
Well I admit the fact that science is indeed for the generation today … of course I too participate fully I’m a doctor and I still earn outside my field😊…. My greatest happiness is the $ 64,000 weekly profit I get consistently from my $15,000 investment despite the economic fluctuation , that’s how do dedicated I can be
Porsche were told the rear engine format was dumb and backwards (not literally) but they persisted and made one of the most iconic series' of sports and supercars in history. Wouldn't bet against them being the ones to persist with ICEs and refine something dumb and backwards to the point of 'flawed perfection'.
Hydrogen has some serious limitations, it happens to be the smallest molecule there is and therefore it's very hard to contain. The second problem is that hydrogen is also very reactive with several types of materials and changes the physical properties of these materials, mostly making them brittle.
so you're in for a whole night of suck, squeeze, bang, suck, bang and blow instead of the usual suck, squeeze, bang and blow in a new Porsche. Finally Porsche has found a way to make it last longer
@6:02 he says "Water vapor is not harmful at tall." Wrong! The most common greenhouse gas is actually water vapor, like in clouds. But because water vapor quickly leaves the atmosphere as rain, we don’t have to worry about our “water emissions.” On the other hand, warmer air can hold more water vapor without causing a rainstorm. So as the planet warms, we will tend to have more water in the atmosphere at a time-and that does heat the planet.
2-strokes suffer ring damage from the cylinder ports. I wonder if Porsche will avoid this issue or if the motors will need frequent cylinder, piston and ring replacement like 2-stroke engines. The conventional 2 stroke engines are easier to perform a top end replacement due to lack of overhead valves. This Porsche engine has overhead valves which makes it way more complex for a top end rebuild.
Ferrari's turbo / supercharger is overly complex. Use a CVT and step up gears to spool up the turbo's compressor, eliminating lag. As exhaust builds, the turbine powers the compressor. Instead of a waste gate, the CVT ratio changes, applying the excess power from the turbine to the crank. The CVT is needed because boost with the centrifugal compressor increases by RPM, very little power at low RPM. If you used a TVS style roots compressor, and step down gears from the turbine, you can eliminate the CVT.
Hydrogen isn’t happening on such a scale due to costs, same with e fuels in the near future. This technology looks good but we probably won’t see any implementation until way after the ICE ban comes in 2030.
Finally some original designs instead of just putting more boost to older block. If the things that i hear is what you had said; i saw good engine improvements.
Upside-down engine... will be fantastic... especially after its sat there for a few weeks allowing the oil to seep past the piston into the combustion chamber, fouling the spark plug, and cracking the head when you crank it up.
That stroke order in the explanation got mixed up a bit. The 6 strokes are suck-squeeze-bang-squeeze-bang-blow. The first bang is extended to also 'suck' from the bottom ports by opening a top valve with the right timing to let (some) exhaust blow out at the top, which creates a draft going up.
Well those all sound like incredibly reliable engines that wont have some sort of serious issues down the road.... IMS, RMS, bore score, cracked headers,........
Ferrari may be using an inverted engine for the first time on a road going vehicle, but this isn't the first time an engine has been inverted. I think this was mastered by the Germans in WW2, when they fitted the engines of the fighter's, like the messerschmitt bf 109 and the focke wulf 190 upside down to lower the nose of the aeroplane giving the pilot a better field of vision out of the front of the plane as well as easier maintenance on the ground and an overall lower centre of gravity! The Focke wolf engine BTW, was made by BMW, although i'm sure they won't be using that fact in any marketing ads anytime soon!
Hydrogen has one major problem that doesn't get addressed: It tends to turn the oil into margarine. Water is the product of this fuel (along with NOX) and invariably it will get into the oil. With disastrous results....
The problem is when you start changing the stroke you're going to change the sound. Just like when they started using small block engines like the ls rather than big block engines. And yes there is a difference in the sound
Just when we think we're done with internal combustion technology and we've extracted every bit of performance out of it, it turns out there is always a little thing you can change to squeeze out a little bit more..

had my ass going cross eyed just watching the video, i know its shitty to say but homie needs to wear sun glasses or something lol its more than a little distracting
Classic prompter reading behaviour
There a couple of devices and tricks to have the prompter in front of the camera, but it looks like they didn't manage to do that here.
He’s reading off a prompter
He was staring at my tits.
Hope they get successful and make it available in regular cars
It will never happen.
It would. Porsche will rely on other manufacturers purchasing the rights to use their design.
If Porsche is the only company to use this the number of fuel powered vehicles reduces resulting in fuel prices being increased to make up for the reduced amount of fuel being purchased.
Producing petrol for vehicles is a long, expensive process. Why would they continue producing fuel, importing it and then transporting them to fuel stations and storing it if only a fair few need it?
they are owned by volkswagen AG along with audi
expect to see this engine in a few years in the Audi S4 or some Cupra SUV
No chance. Won't be too long before most BEVS will be cheaper than ICE vehicles. Look around, more and more EVs on the road, more and more chargers. Peak global ICE sales passed by a few years ago.
@@markwilson2069 yeah but EVs sucks tho, you can check statistics, people have stopped buying so sales are gradually decreasing and it's not reliable or more efficient regular gas car
The 6 stroke Porsche engine looks like a 4 stroke and 2 stroke engine combined. It’d create lots more power but not sure how it’d be more efficient? The 2 stroke part of the cycle would bring down efficiency vs a regular 4 stroke.
Because you’re scavenging energy by pulling in gases from the first combustion stroke and re igniting them. More power and cleaner.
They don’t say it’s more efficient, it can make more power and reduce emissions. Reducing emissions has nothing to do with fuel economy it’s about how clean the fuel is burned. (See dieselgate, vw made their diesels more efficient by letting them pollute more.) This system will basically act like an EGR system but instead of sending exhaust back in the intake it does it during the 2 extra strokes, added benefit is you have more power strokes.
If Porsche is indeed intending to put that into a production car it will actually be better.
I too am rather sceptical of the concept, but I ain't gonna doubt Porsche if they decide to have a go at it.
@@Matt_10203CO2 doesn’t burn my G. How wrong you are, kind of scares me.
I bet you put fires out with petrol don’t ya haha x
U didn't get the point. Sit. @@Hrossey
0:45 - It's worth noting that Porsche hasn't managed to get the carbon capture working (because it's fundamentally unworkable) so they're just using CO2 from breweries. Which is a standard way of getting CO2.
For me, what makes synthetic fuels so promising isn't the method of getting CO2, it's simply the fact it uses CO2 at all. I've seen some claims that modern small Petrol-Hybrid engines are so clean that they would potentially emit less than is needed in that process. Now obviously, that's marketing speak and so comes with a very large pinch of salt, but that is a massive improvement.
Plus there would be no need to adapt cars or fuel stations as an ICE wouldn't notice the difference between dead-dino fuel and synthetic fuel.
@@deaks25 A 100% clean burning engine would put out exactly the same amount of CO2 that it took to make the fuel. If it put out less that would actually be bad, as that would be particulate matter and unburnt fuel.
But synthetic fuels will never be more than a marketing gimmick. They require far too much energy to produce.
@@drunkenhobo8020 That's not even remotely true. Synthetic fuels are not simply the reverse of the combustion process, and different cars emit different levels of CO2. If a gallon of synthetic fuel used 500g of CO2 and the car it goes emits less per gallon, that is a carbon negative result (Yes, that number is just an example).
And why would they be just a gimmick? ICEs are not going to disappear overnight in 2035 (assuming that deadline even remains), there will still be hundreds of millions of ICEs on the road and will remain so for several decades. Arguably reducing the emissions of ICEs is FAR more important than BEV development.
But let me ask you this then; what IS the solution? You've rubbished hydrogen, now you're rubbishing synthetic fuels. BEV technology has it's own massive environmental problems as well when it comes to mining lithium, and the issues around energy density will remain, even with solid-state batteries, never mind the infrastructure and power generation questions that EVs are inexorably linked to.
So what do you suggest is the solution? Or should the car just doomed to extinction?
@@deaks25 You clearly don't understand anything about chemistry - yes, synthetic fuels are effectively the reverse of the combustion process. What you said makes absolutely no sense; carbon is a real physical thing, it can't just disappear. You can't end up with less of it after burning it. If it's cleanly burnt, you'll end up with exactly the same amount of CO2 you used to make it.
They're a gimmick from oil companies and ICE marques trying to pretend that there's still life in ICE. There isn't.
You're telling me all I need to know when you bring up lithium mining. A 50 kWh pack uses 8kg of lithium. It's a tiny proportion. The car it's in will weigh around 1600 kg. Why not focus on the other 99.5% of materials?
If you think power generation is a problem for BEVs, just wait until you hear how much energy hydrogen or synthetic fuels would take to produce.

Wow Mat! Never thought I would hear a good technical explanation on CaeWow but, this video was great and did a wonderful job on explaining the new engine developments at Porsche and Ferrari. Well done.
My cousin did turbo and supercharged 4cy back in the late 90s. 700hp and 720lb. I've been calling this for a long time.
Pretty sure there was a lancia in the 70's or 80's with a "twin charged" engine as well.
Gotta love Porsche innovation
"stroke" of genius.
The whole idea of efficiency and a cool sounding engine will never work together. Any sound you hear is a direct result of vibrations which are inefficient. Thats why the most efficient petrol engines dont make much of a sound, but the horribly inefficient naturally aspirated v12s produce the sweet sound of POWERRRR
Not all V12s are like that. Some of this big engines are for luxury cars.
I've driven a Toyota Century V12, it was so silent and smooth, it just reminded me of driving a Tesla Model S.
Then I also drove a W12 Bentley Continental and it was loud, just like you mentioned.
I do think that electric motors and their inverters can sound pretty cool, in race built EVs. Also the Rimac cars.
lol you know that the noise generated by an ICE is like a minuscule fraction of the inefficiency. Thermal and mechanical inefficiency by comparison is much much more severe in ICE.
The creative ingenuity of the human brain is astounding 😮
I'm blown away by how high-tech these engines are getting.
we've come a looooong way since the first ICE engine. I always kind of expect that we'll peak at some point, but it seems we're not there yet.
2:03 matt explaining his actors how to do it.
That's going to sound like a backfirng vacum cleaner😂
A vintage Kirby vacuum..
Its going to sound like a normal four stroke at lower rpm so when this is at 1500rpm it will likely sound like a normal one at 1000rpm.
Remember there is no exhaust between the combustion events so you're going to have one exhaust pulse per 6 strokes instead of 4.
so many vaccum cars nowadays
just so China and India polute 5x as much for everything we dont polute.
and while our good leaders and celebritys fly short distance with their private jets and helicopters.
Nah, it's most likely sound like 2 stroke.
We got the topmost engineers in the world criticizing porsche's engineering on a random yt channel👍🏻
Essentially, Porsche designed a 4stroke plus 2stroke engine. Will it run on 50:1 mix fuel?
why would it? It still has the oil sump in there so the crank case and camshafts still get oil. My question is when the piston is up, and those holes are exposed to te bottom end, wouldnt the oil find its way inside the holes and after it to the chamber?
I don't care about Porche or its new Engine. I am more impressed with the person who edited this video. His editing is really good.
You never mentioned the supercharger in the Ferrari at all Matt. Do we assume it works like any old supercharger and totally disconnected from the complexities of the turbo charging system ?And where the hell are they gonna fit that ??.
Carwow more vids like this pls real informative break downs on how things work.

"Porsche Just Saved Internal Combustion for RICH PEOPLE who can AFFORD one of their vehicles" should be the title.
Not really, if the engine works itll find its way into consumer targeted vehicles

@@aleksjenner677 Far be it from Porsche to stand in the way of progress.
I fail to understand how that is going to save internal combustion engines for porche
Everyone is always saying pouting and crying over maintenance issues and how EVs are simpler, when the reality is that Porsche didn’t even need to do this to begin with. They could’ve taken the easy way out and continued to make EVs in the market, but they choose to continue tailoring to the enthusiast and make cars that have a soul. They know car enthusiasts like the rumble and sound of a gasoline engine; the feeling it provides. They choose to push through the regulations that keep getting stricter. It's through R&D that this technology will get better. I may not have the money to buy this, but I'm glad this exists, even though it might be rough around the edges at first. If it's anyone that can perfect automotive technology, it’s Porsche.
Thanks for keeping us updated
Just because they've patented it doesn't mean they're going to use it, R&D is a great tax relief for businesses you know 😂
Can you name at least 3 patents of the last 20 years that haven't been used?
Extremely curious what a 6 stroke will sound like 😯

with the ports in the cylinder, it’s basically a 4 stroke mixed with a 2 stroke engine.. 6 stroke
When I was training to be a diesel mechanic the professor pointed out that at the most basic level an automobile needs: 1 - a source of stored energy, 2 - means to convert that into kinetic energy, and if you ever want to stop the vehicle 3 - means to convert kinetic energy into something else.
Electric vehicles ace two of those points: the motor can be 90+% efficient at converting stored energy into kinetic energy, and regenerative braking reconverts kinetic energy back into stored energy on braking. A good internal combustion engine is closer to 35% efficiency. I know a lot of people are vibration junkies, but objectively motors are superior to engines. Using internal combustion to convert hydrogen into kinetic energy is purely an exercise in wasting energy just so people can hear vibration. But if engine noise is an important thing in your life, that might be a rewarding tradeoff.
However, it will be very, very difficult to match the convenience of liquid fuel as a source of portable stored energy. Finding efficient means to convert liquid fuels into electricity might be worth a closer look. If you are aware of efforts to do so, I would love to hear about it.
As the 1980s were to personal computers, I think the present is to transportation. The advances in energy storage, efficiency, and manufacturing are going to move quickly.
@@mtnman1984 Overall, technological advancements never stop fully yes, but you just used your own argument against yourself. As moores law which, claims a constant improvement in semiconductor performance, is currently proven wrong as the processor speed improvements slow down, combustion engines progress has slowed down already long ago when you look at the data. There is always an end to evolution when you are not whilling to change the general approach, and this new proprietary maintanance hell of a machine wont change that fact either.
@@floppypaste I'm talking about technology advancements in electric drivetrains, power conversion, and energy storage, but thanks. 😆
Not a big fan of EVs but i'm also a number/science buff and a very objective individual. Electric cars are the way to go....Tesla's latest Model Highland Long Range has a claimed autonomy of 705 km...let's say realistically it's more like 550-570 km.
It's getting at a point that I can hardly justify not buying one...
For now i'll keep my 2 Mercedes but just because in Italy, because of stupid regulation I cannot charge an EV in my underground garage (I live in a residence)!
@@SpaghettiKillahfundamentally people who are buying EVs aren’t doing so because of the love of EV. It’s for practicality. People who love performance ICE love it for the feel of a high revving ICE engine screaming at you while you send it into a corner. EV cannot match that raw aggression.
What are you doing in this van Math? Not your van anymore! 😊
A gift is a gift! 😂

I love this development in the automotive industry so much. I was never interested in plain 4 cylinder ecobox engines for commuters that don't car. For all I care, those cars can be electric. But experimental sports car and bike engines. Man, that's where it's at. This stuff really fascinated me, really getting into the intricate depths of the technology and its upkeeps
We may not have all cars going EV, but all this help push internal combustion tech forward in an insane way. Fighting for survival is a powerful motivator.
Unbelievable amounts of engineering hours and genius ideas to improve the combustion engine just a little bit more.
And then there is the electric motor without all that stuff.
We getting more efficiency with this one!

Wow, Porsche is really pushing boundaries with this 6-stroke engine innovation! 🚗💨 Just when it seemed like electric vehicles were taking over, internal combustion is getting a powerful upgrade. Can't wait to see how this impacts performance and efficiency in the future. Go Porsche!

I read, at least 3yrs ago, that Porsche would keep at least one 911 variant as ICE. This might not be a road going version but a track day special.
I could listen to that guy talking about complicated hybrid drive systems, or cheap doors.
I think he's ace.
Hydrogen is $36/Kg in the only state in the US that sells it. You can go about 60 miles per Kg in the 182 Hp Toyota Mirai. However, that has a Hydrogen Fuel Cell which is about twice as efficient as a Hydrogen combustion engine. Imagine paying over $1 per mile to fuel your car!
Exactly. I still do not get why people think that anyone will pay twice for the same result. Just for the sound? Even if hydrogen gets cheaper, it will most likely be more expensive than electricity per mile. For anyone who drives mostly medium distances, EVs are the obvious choice today and will be in the future.
plus 99% of the hydrogen on the market is made from hydrocarbons.
Saving Internal Combustion for only 200k
I fail to understand how this is going to save internal combustion engines for porche
@@Jojo-o6o6w More efficient, more power, runs on their own sustainable fuels. I think there's still so much more to the internal combustion engine that hasn't been tapped.
@@Jojo-o6o6wWell the peasants will roll around in Teslas autonomous Taxis, and rich people can still drive Porsches.
Less efficient than EVs, not more sustainable then EVs, much more costly even than regular fuel, impossible to produce at mass scale. So your conclusion is wrong
Snide and as ignorant as one can get!
First of all you know nothing about wealthy people. If you knew anything, you’d know that wealthy people usually don’t even drive. They have personal drivers for that and usually take the back seat because time is money. Ever heard of that? Case in which a future truly autonomous vehicle will be a no brainer. Tesla has so much more going on that the German (and not only) auto industry are still playing catchup. There is a reason after all why Tesla’s market cap is much more than the whole German auto industry combined.
All I see on this, when if breaks it will fully fook the engine big time
It will cost more than the car to replace
I'm so disappointed in Toyota for picking the Yaris over the GT Starlet which has a bigger fan base.
The GR Starlet.
I want to hear these engines powered up and under load, especially that 6-stroke Porsche.
These are all fears of transitioning from the stone age to the metal age.
Or maybe Porsche just cares about enjoying driving. You can enjoy your self driving EV in the future if you hate driving
No, because we already went through that transitioning stage (stone to metal), the last time we went from electric to ICE.... you know, like 120 years ago (give or take).
@@origaminefretami3480 Nothing wrong with electric driving pleasure. I dont hate combustion engines but noise. The high noise cars are just a toy who loves to get attraction by noise. This way people strares at you that i dont care.

@@ismetates7235 Thats....as wrong as it can get. Sure there are some people that love attention but a good engine noise pleases the driver the most.

Porsche were told the rear engine format was dumb and backwards (not literally) but they persisted and made one of the most iconic series' of sports and supercars in history. Wouldn't bet against them being the ones to persist with ICEs and refine something dumb and backwards to the point of 'flawed perfection'.
What’s wrong with mats eyes 👁️👁️

Cross eyed for sure
Hydrogen has some serious limitations, it happens to be the smallest molecule there is and therefore it's very hard to contain. The second problem is that hydrogen is also very reactive with several types of materials and changes the physical properties of these materials, mostly making them brittle.
so you're in for a whole night of suck, squeeze, bang, suck, bang and blow instead of the usual suck, squeeze, bang and blow in a new Porsche. Finally Porsche has found a way to make it last longer
@6:02 he says "Water vapor is not harmful at tall." Wrong! The most common greenhouse gas is actually water vapor, like in clouds. But because water vapor quickly leaves the atmosphere as rain, we don’t have to worry about our “water emissions.” On the other hand, warmer air can hold more water vapor without causing a rainstorm. So as the planet warms, we will tend to have more water in the atmosphere at a time-and that does heat the planet.
At least they’re innovating. Actually might be a cool era in automotive history.
2-strokes suffer ring damage from the cylinder ports. I wonder if Porsche will avoid this issue or if the motors will need frequent cylinder, piston and ring replacement like 2-stroke engines. The conventional 2 stroke engines are easier to perform a top end replacement due to lack of overhead valves. This Porsche engine has overhead valves which makes it way more complex for a top end rebuild.
Ferrari's turbo / supercharger is overly complex. Use a CVT and step up gears to spool up the turbo's compressor, eliminating lag. As exhaust builds, the turbine powers the compressor. Instead of a waste gate, the CVT ratio changes, applying the excess power from the turbine to the crank.
The CVT is needed because boost with the centrifugal compressor increases by RPM, very little power at low RPM. If you used a TVS style roots compressor, and step down gears from the turbine, you can eliminate the CVT.
Hydrogen isn’t happening on such a scale due to costs, same with e fuels in the near future. This technology looks good but we probably won’t see any implementation until way after the ICE ban comes in 2030.
ICE will not be banned.
Finally some original designs instead of just putting more boost to older block. If the things that i hear is what you had said; i saw good engine improvements.
Matt's mention of Jeremiah Burton is EPIC!
I thought Matt mentioned Jeff Gordon.😅
Upside-down engine... will be fantastic... especially after its sat there for a few weeks allowing the oil to seep past the piston into the combustion chamber, fouling the spark plug, and cracking the head when you crank it up.
the way you say patent is killing me lol "pain-tent" love you matt
Why does he look like Clarence the Cross-Eyed Lion?
Is this a side effect of six-stroke engines? 😂
These systems are so innovative. However, they also sound expensive and hard to maintain.
GREAT report 👏 . You've STILL got IT 😂
Leave it to Porsche- best engineering in the auto world
That stroke order in the explanation got mixed up a bit. The 6 strokes are suck-squeeze-bang-squeeze-bang-blow. The first bang is extended to also 'suck' from the bottom ports by opening a top valve with the right timing to let (some) exhaust blow out at the top, which creates a draft going up.
Well those all sound like incredibly reliable engines that wont have some sort of serious issues down the road.... IMS, RMS, bore score, cracked headers,........
Ferrari may be using an inverted engine for the first time on a road going vehicle, but this isn't the first time an engine has been inverted. I think this was mastered by the Germans in WW2, when they fitted the engines of the fighter's, like the messerschmitt bf 109 and the focke wulf 190 upside down to lower the nose of the aeroplane giving the pilot a better field of vision out of the front of the plane as well as easier maintenance on the ground and an overall lower centre of gravity! The Focke wolf engine BTW, was made by BMW, although i'm sure they won't be using that fact in any marketing ads anytime soon!
Hydrogen has one major problem that doesn't get addressed: It tends to turn the oil into margarine. Water is the product of this fuel (along with NOX) and invariably it will get into the oil. With disastrous results....
The problem is when you start changing the stroke you're going to change the sound.
Just like when they started using small block engines like the ls rather than big block engines. And yes there is a difference in the sound
Just when we think we're done with internal combustion technology and we've extracted every bit of performance out of it, it turns out there is always a little thing you can change to squeeze out a little bit more..
Man, that will sound mega. Can't wait to see it actually come to life!
2:00 sounds like a good time 🤣
Porsche saved internal combustions every year since its existence. God with us.
The Porsche with that engine swap could be epic also.
