The moment you realize the prius is all about the transmission, not the battery...
That’s why the sticker on the back says “Hybrid Synergy Drive” and not “Battery”.
Yea they make incredible use of a planetary gear set, much more so than the planetaries in an automatic trans. I think it's brilliant they made a flawlessly smooth transitioning device that allows additive torque input from 3 different sources. It runs on simple, normal trans fluid, and it shares a separate coolant loop with the inverter/converter solid state control box. Separate from the engine's coolant I mean. And all this stuff runs north of 300-400k miles before even pretending to have problems. And it's certainly worth the battery cost every decade or two since it pays for itself in saved gas money in 2-3 years.
My brain did blow up with that realization. What an elegant and simple solution they made
This is awesome! You opened my eyes for how amazing a hybrid engine really is.
It gets even more awesome most hybrids including the Prius have an Atkinson cycle engine with roughly 40% thermal efficiency.
This is one of the best explanations of how the hybrid engine works. Superb graphics and dialog make this a must-see for all Toyota Hybrid car drivers, such as I. This documentation was not easy to do and the creator spent a lot of time. It is worthwhile and I thank you for the excellence and passing on the knowledge. Well done.
I second this. Thank you Mr. Niels Blaauw sir for this wonderful explanation!
There is always something special to me about these "sketchy" animation videos. Like they just explain it casually and straightforwadly rather than trying to have a glamorous looking presentation.
Sir, your video is a piece of jewelry - you're truly an "internet angel" producing high quality content and promoting interest for technology and science. My profound respect and gratefulness!
Well said

I have had a Toyota Camry Hybrid since February 2015.
When I drove it away from the dealership, it felt like Star Trek technology to me.
After almost four years, it has been 100% reliable with no break downs whatsoever!
Just got an 08 Prius myself. Had a good laugh when I realized it doesn't even have automatic headlights (it's an option)...Good god I hate unnecessary beeps :D But yeah, feels weird after a Mini.
Another channel removed and opened up the ICE of a Prius after 200,000miles/300,000km. It was like brand new. The battery and occasionally the inverter coolant pump is about the only thing that can go wrong with these cars.
Wow this is the first video I've watched that actually makes hybrids make sense.
Probably the best explanation of Toyota's hybrid drive on the internet. Excellent.
This is a great explanation. We bought a Prius in 2008, and have been really happy with it. An amazing vehicle. Almost no maintenance, after 151000 miles, and excellent mileage. Lately the battery has shown decreased performance, but we still love it.
I have owned a bmw, a Mazda, a Kia, then a Prius, then another Prius. Only the Prius fits the definition of “durable goods”
Just came across this. Absolutely fantastic! What a labour of love. I love animated CAD and thoughtful explanations. Very enjoyable and recommended to a number of friends.

Yeah - very helpful video - explains in a way that I can start to physically grasp how it works. You're right it's the pictures that do the trick.
This a beautiful presentation - Simply brilliant! Your motion graphics spared you the effort of at minimum 5,000 words. I'm subscribed and looking forward to your further efforts. thank you-
Over the years I've come back to watch this video. This guy really did a great job of simplifying and teaching hybrid this system.
Still the best explanation of the Hybrid Synergy Drive I've seen. Thank you.
That's the kind of videos TH-cam should mainly be used for !
What a fantastic video, and amazing use of 3D software! I asked the man in the Toyota shop yesterday how the engine coupled into the wheels along with the motor - did it use a clutch of some sort - and he fobbed me off with utter nonsense. Now I understand! The explanation given here could not be bettered, and the two-motor-generator system with planetary gears has to be the new challenge for youngster to grasp, just as the differential once was. I wonder if anyone has built it in Lego yet! Thanks very much.
I suspect that very few mechanics (even those working at a Toyota dealer) understand how the hybrid system works. It so seldom needs repair that only a few specialists ever work on it, just the rest of the car and things like cooling system, exhaust, brakes, suspension, etc.
This is a really good video. Starting off by explaining the problems engineers were trying to solve using clutches and gearboxes sets the context and makes you realise just how amazing the HSD is. Great animation - it must have taken a lot of effort. Thank you.
Outstanding explanation .. watched several times to fully understand .. I play at 75%, stop frequently, replay and reflect on the actions inside the planetary element .. a pleasure to learn this. Thanks a million !
Almost didnt watch this….glad i did. Amazing explanation! I was amazed at the detail and engineering genius in discussion
What a great video! Well done, Niels! You have done something which is so necessary: you have used graphics and words to explain CONCEPTS. This is so crucial in explaining the IDEAS behind how things work. Indeed, your are an exceptionally good teacher.
This was the best explanation of a hybrid I’ve ever watched!
The data presented here blew my mind. So did the illustrations. Great 3d modeling and beaking down of complwx systems. Thank you for this.
I love the little flames in the cylinders. Lovely!
This is like some of the best powertrain modeling I've ever seen... The detail on just the differential is amazing.
Every now and then as I'm cruising Arizona freeways at 84 mph (135 kph) getting 47 mpg I wonder how it all works. Niels- thank you for explaining it!
This is amazing. It hadn't occurred to me that the resistance from the generator could directly act as the clutch.
And, effectively, a torque converter! Ingenious design.
But it doesn't. Before introducing the planetary gear set he shows an interesting design which is almost completely unlike the Prius transmission.
Absolutely brilliantly done and narrated.
After watching your broadcast, I went and bought a secondhand prius II and am very happy with it.Thank you for your video
He should get a commission!
Family has two hybrids, the Mitsubishi Outlander PHEV and Ford Fusion Hybrid, the latter actually employs the same identical powertrain as the Toyota Hybrid Synergy Drive as Ford & Toyota cross licenses patents. The lack of gearshift and no intrusive engine start stop is something that I learn to love in driving hybrids. Even better understanding regenerative braking- no more guilt of riding the brakes and replacing pads & rotors when the MG2 can take it all back and give you more electricity to get even further.
MG2 cannot "take it all back." You will lose power riding the brakes. Nothing will ever beat coasting for efficiency.
A brilliant mind is able to understand complex things, a genius is able to understand complex things and explain them in simple terms to those who don’t understand
"Anyone can make the simple complicated. Taking something complicated and making it simple, man, that's creativity." - Charles Mingus
That’s really not genius. That’s being a good teacher. Genius is looking at what everyone has looked at but seeing what no one else has seen.
One of the best explanation of how Prius hybrid drive work. very good video🥰🥰🥰
I think it is brilliant to use an generator as a clutch. [that is what MG1 is doing. It is acting like a clutch, all the while it is a generator. The friction that normally would have been lost as heat in a conventional clutch is converted to electricity that runs MG2] Genius!
@ Poker Channel Yeah that's pretty cool. I wonder why hybrid tech isn't more or less mandatory - since it seems naturally more efficient with fuel, in a number of ways.
The best explanation I’ve ever seen. Man you are the master of logic and visualization!
An amazing design by Toyota at that time in 1998.
Absolutely BRILLIANT
Best illustration/explanation I've seen on the HSD. I could even say it's the best explanation I've seen on anything on youtube. Well done and thanks a lot!
There's also the old black & white "more spokes" video on the principle of the differential that has the same step-by-step explanatory quality. th-cam.com/video/yYAw79386WI/w-d-xo.html
Yeah I like that one too :)
Very impressive explanation of the Prius. Complicated to say the least. These cars are ubiquitous. They're everywhere. One of Toyota's greatest successes.
I know this is a few years on, but it’s the first time it has ‘come to life’ as it were. You graphics for explaining how the planetary set works is effective - better than the original Toyota presentations.
Note that the second planetary set connected to MG2 (the traction motor) is really a fixed ratio reduction set, allowing the motor to run faster.
The ‘smaller’ version of this drive (the so-called “hybrid synergy drive” (HSD) ) does not use a chain to connect to the differential gear set - it’s a short shaft from the ‘ring gear’. Although the mechanical arrangement is well described, there’s a bit more to it! In particular, there are three inverters (to work with the motors, which are variable frequency a.c.), and a pair of d.c. converters. The most important battery in this type of car is the high voltage d.c. one - if it’s dead you’ve had it, but if the smaller 12V d.c. one fails, that is easy to overcome with a conventional external d.c. “jump start” device.
The contractor for the HSD is Aisin-Seiko - at least 30% of it’s shares being owned by Toyota; it’s own site may be of interest.
Also worth noting that the choice of this system is related to the use of the Atkinson cycle for the engine (most of the time), so as to optimise it’s thermal efficiency, at the expense of reduced torque/power at any given engine speed. What is nice about it is that traction motors have maximum torque at zero speed.
After spending an afternoon trying to get the hang of the Toyota e-cvt that's appearantly in my Rav4 Plugin, this video was the best and actually manages to explain how it works. Thank you Nils!
I just bought eCVT car, and wanted to learn about how eCVTs actually work... Your video explained me a lot!
@8:50 is a good quick eplanation of why hybrid gets more MPH: The engine either is running at an efficient RPM or not running at all. Engines apparently have a window of RPM which is most efficient. Hybrids allow for an engine to get away with only running in that narrow window of efficiency.
It's more than that. The engines used on hybrids are atkinson engines. These engines are far more efficient than standard petrol (otto) engines, but at the expense of torque. The motors make up for that loss of torque where required.
@@MikelSyn The ICE cubic capacity is also larger to make up for the power disadvantage of Atkinson Cycle.
This is so phenomenal! Thanks for making this 3D animation.
Excellent presentation! You're a genius! Thumbs up! It is clear that advances in battery technology will completely eliminate the need for the ICE
Best explanation of the hybrid drive I found so far! Thanks!
ASMR for auto mechanics. Haha.
This dude needs a playlist for falling asleep. Well spoken and made video.
Very helpful video - explains in a way that I can start to physically grasp how it works - the pictures make it all come together.
Brillant explanation. I know someone said the same below me, but it´s the expression i found to describe this.
Great clear graphics. Good structured presentation.
I hope you are teaching some lucky people.
Thank you Niels! Nicely produced and animated, give a lot of clarity to my Prius.
A work of art, intellectual art; beautiful. Thanks Niles.
What a great video. This is why the internet is special.
I understood 50 percent of that. Still better than what I used to think was magic. Gears, capacitors, batteries, Motors. ME LIKEY.
Thanks Neils for your clear explanation of the workings of the Prius. You have done a great job of it.
What an amazing video, thanks Niels for all your work. I’m not 100% sure how the damn thing works but I’m much closer and I’ll continuing studying so I can get tp a point where I can explain it to my granddaughter.
Thank you. An excellent description. I now understand how it works.
This. Is. Amazing. Non-engineer here with a Prius. Fascinating. Thank you.
I'm still tryin' to wrap my brain around all those moving parts...wow! Good job, Niels.
Great job sir. Thank you for going back and forth on the different types too. That made it much easier to understand
this is so much easier to understand than explanation on paper. so awesome.
Brilliant. Like your humor as well. I wish Toyota would make a transparent (see-through) Prius so we could see the real thing in action on a display stand. Their hybrid system is one of the most wonderful improvements in automotive technology and I don't think many people appreciate how amazing it is. People complain about the design of the Prius body and I do blame Toyota for a self-inflicted wound that reduced sales of the Prius, and thus benefits to cleaner air and less gasoline consumption. Fortunately they are now putting their hybrid system in more conventional looking vehicles. You have done a great service to help with the understanding of how this system works. Thanks.
Brilliant video. Complex engineering made much simpler to understand. I am sure Neils you will give it the required update and revision when required.
One of the most informative animations I have ever seen.
You did an amazing job of breaking it down and making it logical and relatively easy to understand!! Thank You!! You have quite a gift of logical communication!
That is a very good demonstration and I now understand how it works, thank you so much!
Almost understood it! I'll get it second time round.. Thank you!!
I have a 2014 Prius, a 2015 Avalon and a 2017 f350 power stroke. All three are excellent for their unique purposes and design strength. Ideally each will last the duration of my life.
Nice explanation! I always wondered exactly how this system worked and it's simpler than I thought. Loved the graphics. Made it much easier to understand. Thanks!
An acquaintances 2001 Prius started playing up, ICE engine would only run for 12 seconds then stop, main battery was very low, eventualy it stayed running and they drove it to a Auto electrician, I think he added ATF to the invertor coolant too, local garage told him it was the Autotrans filling point, who knows what damage he's done.
What surprises me as with all the onboard electronics and computers you don't get very good diagnostics on the 2001 model and obd2 reader doesn't seem to work on Japanese models.
this is such a good animation....thank you so much, toyota needs to use this why the E-CVt is much better than those older clunky mechanical CVT units....
Fantastic job Neils! Thank you for explaining it so clearly 👍
Really impressive work!
Dear Niels, thank you for this nice explanation! It's far the most easily understood all over the internet!
Beautiful engineering. Thanks for illustrating this.
Thanks for your fantastic presentation and explanation. Talking slowly so that every one catch up this new technology.
Thank you for all your work presenting this fine video. I now have a good understanding of how my Prius Plug in works.
EXCELLENT video & explanations. my prius just died & stranded me not far from the middle of nowhere last week. your video allows me to better understand what happened.
Your explanation and animation are awesome! The Prius Drive is truly one of the most advanced and smart, and yet simple invention.
Thanks for such a wonderful video explaining hybrid technology.
Amazing! Was looking all over TH-cam for someone to explain this
This is the best explanation of the HSD bar none, ever.
A truly world class video.
Awesome Video! Wonderful explanation. Many thanks for the video!
Best explanation of Prius drive train. Thank you!
Studying for ASE L3 right now, this was a great starting point, thank you.
Weber auto and your video just blew my mind. This is all i was looking for the past 3 days and yet you did it. I drive an Auris II and i finally knows how it works thanks to weber auto and you. Keep up the great work!!!
thanks, pretty amazing video. I drive a Prius. had no idea it was this complicated.
Nice explanation, thanks. I have driven my friends on a couple occasions and found I really like the car. Will probably be my next vehicle in some iteration.
Thank you Niels, very informative & cleverly done.
Thanks very much for taking the time to put together such a clear and concise animation. :)
Hats off to Ford engineers for their 1969 patent. Excellent video animation.
Toyota waited 28 years for that patent expiration... should've been 20...
We could have had hybrid Ford Thunderbird and Mustang
For those commenting that these systems are more complex than a standard motor, they're actually simpler, as they do without cluch, gears, and the whole mechanical transmission. This takes a lot of stress out of the whole motor/transmission system, and in fact the thermic motor in Toyotas works in a different fashion than a standard car motor, as it is not supposed to work on a full rev range, but it can just work in a limited range, maximizing efficiency, as the other 2 motors take active part in transmission. Thus Toyota hybrids are well known for very high reliability.
I believe the Heat Engines in the first Prius models ran on the Atkinson Cycle, but the later ones ran on the Otto cycle....
@@Dave-wy4so wiki says they run on a Miller cycle, which should be a simplified mechanical version of the Atkinson cycle.
Also eliminates the starter motor, starter cable, starter solenoid, giant 12-volt battery, alternator and its belt, (all of which are common failure points) idling, and failing to start in cold weather. ALL Toyotas are known for reliability -- check the annual Consumer Reports "Frequency of Repair" edition at your library. The next time you watch a nature documentary filmed in the middle of nowhere, you'll see nearly everyone drives a Toyota.
@@CharlieGosh True - and anyone venturing into the Australia outback wouldn't be seen in anything other than a Landcruiser, unless of course they had a death wish in which case they'd drive a Land Rover..lol
Just bought one, thanks for this perfect animation and explaining!
Danke, super Video, gut erklärt und gehört in jedes Klassenzimmer!
There really is something magical about this video. Can’t put my finger on it. We’ll done!
This must be the 9th time I watch this video. THANK YOU!
This makes me appreciate my Prius so much :D
Very good! I drive a Prius for deliveries at work and notice some tremendous RPMs on the MG while in engine braking mode and also when in cruise control mode and reduce the cruise speed while going downhill. You can really hear the high speed winding up of the motor/generator
I had a fair understanding about the hybrid engines but you brought it to a real full understanding of it _ I wanted to thank you _ and I will recommend this video to Prius drivers...
Thank You for that incredibly clear and understandable video!
Toyota Prius Prime (plug in hybrid) you can drive further and faster with much bigger battery, which is ideal for everyday drivers, long distance etc. An ultimate car :D
Beautiful animation and great explanation. Thank you
Thanks for the brilliant explanation. Currently have a 2012 Vauxhall Insignia and I'm thinking about changing to an Auris, and am now more in line to get one now after the science has been explained 😊
Oh, best explanation I've seen ... very professional........ fyi the third gen does not have a chain as stated.
This is why I bought the prius! It's so fascinating and very well engineered. Even though lots of people hate it.
The cool thing about Toyota in my opinion is that you don't have to buy the Prius to get a hybrid engine. You can have it normal cars now, too. So all the benefits without the Prius looks... Unless you're into that, of course ;-) .
@@tobiasmeier6887 True. But I don't think there's another toyota that matches the efficiency of a prius due to weight, engine, etc? I just like how focused they are with how efficient the car is.
@@dw2843 I'm guessing the Prius' aerodynamic shape would add to the efficiency in comparison to other Toyota models. So yeah, I get your point...
I HATED the prius, everything about it, everything it stood for. I'd laugh at them on the road in the various sports cars that I've owned, various trucks that I've owned. Then I got the chance to buy a USDM gen 1 for $500... It's the best god damn car I've ever owned.
It's a great car. It just looks gay.
Great video! Amazing explanations! Thank you for sharing!
the best explanation I've seen yet!! - Thank you!
