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
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

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!
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.
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.
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.
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”
Wow this is the first video I've watched that actually makes hybrids make sense.
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.
Probably the best explanation of Toyota's hybrid drive on the internet. Excellent.
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.
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-
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 !
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.
Matt Lee (age 62. And old engineer.)
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.
That's the kind of videos UA-cam should mainly be used for !
Very helpful video - explains in a way that I can start to physically grasp how it works - the pictures make it all come together.
The best explanation I’ve ever seen. Man you are the master of logic and visualization!
The data presented here blew my mind. So did the illustrations. Great 3d modeling and beaking down of complwx systems. Thank you for this.
Thank you Niels! Nicely produced and animated, give a lot of clarity to my Prius.
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.
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!
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.
Thanks Neils for your clear explanation of the workings of the Prius. You have done a great job of it.
This is like some of the best powertrain modeling I've ever seen... The detail on just the differential is amazing.
Still the best explanation of the Hybrid Synergy Drive I've seen. Thank you.
Absolutely brilliantly done and narrated.
Almost didnt watch this….glad i did. Amazing explanation! I was amazed at the detail and engineering genius in discussion
Best explanation of the hybrid drive I found so far! Thanks!
I love the little flames in the cylinders. Lovely!
This is so phenomenal! Thanks for making this 3D animation.
Great job sir. Thank you for going back and forth on the different types too. That made it much easier to understand
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!
This was the best explanation of a hybrid I’ve ever watched!
this is so much easier to understand than explanation on paper. so awesome.
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!
Fantastic job Neils! Thank you for explaining it so clearly 👍
Really impressive work!
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!
A work of art, intellectual art; beautiful. Thanks Niles.
Dear Niels, thank you for this nice explanation! It's far the most easily understood all over the internet!
I'm still tryin' to wrap my brain around all those moving parts...wow! Good job, Niels.
Excellent presentation! You're a genius! Thumbs up! It is clear that advances in battery technology will completely eliminate the need for the ICE
Thank you. An excellent description. I now understand how it works.
Thank you for all your work presenting this fine video. I now have a good understanding of how my Prius Plug in works.
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.
That is a very good demonstration and I now understand how it works, thank you so much!
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.
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 very much for taking the time to put together such a clear and concise animation. :)
Brillant explanation. I know someone said the same below me, but it´s the expression i found to describe this.
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. ua-cam.com/video/yYAw79386WI/v-deo.html
Yeah I like that one too :)
This is the best explanation of the HSD bar none, ever.
A truly world class video.
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...
Danke, super Video, gut erklärt und gehört in jedes Klassenzimmer!
Great clear graphics. Good structured presentation.
I hope you are teaching some lucky people.
Studying for ASE L3 right now, this was a great starting point, thank you.
Amazing! Was looking all over UA-cam for someone to explain this
One of the best explanation of how Prius hybrid drive work. very good video🥰🥰🥰
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.
FANTASTIC VIDEO,YOU ARE THE MAN.THANK YOU SO MUCH.STEVE IN CLEARWATER,FL. 2009 PRIUS 48,000 MILES BOUGHT 2 DAYS AGO.!
This must be the 9th time I watch this video. THANK YOU!
This makes me appreciate my Prius so much :D
Awesome Video! Wonderful explanation. Many thanks for the video!
I just bought eCVT car, and wanted to learn about how eCVTs actually work... Your video explained me a lot!
the best explanation I've seen yet!! - Thank you!
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.
thanks, pretty amazing video. I drive a Prius. had no idea it was this complicated.
Beautiful engineering. Thanks for illustrating this.
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 😊
Thank you Niels, very informative & cleverly done.
Thanks for such a wonderful video explaining hybrid technology.
Thanks for your fantastic presentation and explanation. Talking slowly so that every one catch up this new technology.
This is possibly the best video that explains this drive (and I say that as an engineer). Thanks Neils.
Just bought one, thanks for this perfect animation and explaining!
Almost understood it! I'll get it second time round.. Thank you!!
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.
Niels, thank you . Great animation. Really helps one understand these Toyota hybrids.
Fantastic job; I probably build one myself - all Thanks to how well you demonstrated everything.
Best explanation of Prius drive train. Thank you!
Thank You for that incredibly clear and understandable video!
Very impressive explanation of the Prius. Complicated to say the least. These cars are ubiquitous. They're everywhere. One of Toyota's greatest successes.
Thank you for this video. I will have to watch again to understand better but this really helps me to begin to understand it.
This. Is. Amazing. Non-engineer here with a Prius. Fascinating. Thank you.
Your explanation and animation are awesome! The Prius Drive is truly one of the most advanced and smart, and yet simple invention.
Thank you, this video was very helpful and easy to understand how a torque is transmitted from engine to wheels by locking MG1.
Wow, what an excellent educational video! Big thanks for taking the effort and sharing
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!
Thank you Neils for a truly brilliant video, great explanation with your homeland accent. As we say here in Australia, it’s bonza :) 🤠
Thank you I could understand the mechanical coupling of both the petrol engine and the electric motor,, Excellent Video
That's an ingenious kit of engineering... and very nice animation and explanation... believe it or not, even I got a bit of what's going on with toyota's hybrid drive...
cheers!
You did a fantastic job on this video. Really great. Your accent is great too. Thank you.
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.
Beautiful animation and great explanation. Thank you
Thanks for this amazing video. Now it is much more clear how this called CVT works.
Nicely done. Also it is a brilliant engineering solution.
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.
Great video! Amazing explanations! Thank you for sharing!
Awesome job!!! I have a 2022 Tundra Hybrid on order and this totally cures my engineering curiosity on how the gas engine and hybrid powertrain works.
The Tundra Hybrid does not work like this at all. The new Tundra is a basic parallel hybrid system with a conventional automatic transmission; it is not a power-split transmission as described in this video.
You are brilliant, and a great teacher.
Explained very well. thank you!
First explanation that made sense to me. Thanks man.
Great video. Explained in a very concise pictorial way the Toyota Hybrid mechanism
