If you’re both a tech geek and a motorhead like I am, you’ll definitely appreciate this video, made by the Transmission Lab of Weber State University’s Automotive Technology Department.
It’s a pretty long clip that takes us through the Toyota Prius Hybrid’s eCVT transaxle and how exactly the combination of the internal combustion engine, Motor Generator 1, Motor Generator 2 and Power Split Device – which are all collectively called Hybrid Synergy Drive – move the car. There’s no actual CVT transmission in this car – gear ratios are emulated by MG1, MG2 and the PSD.
If you don’t have half-an-hour, you can skip to the 17 minute mark and watch the remainder of the video, as that’s where MG1 and MG2 are assembled together and the video shows how they interact with each other. The internal combustion engine is represented by a flywheel.

Looking to sell your car? Sell it with Carro.
I’m shocked to know noone is posting here. Where are toyoda fans? But no wonder because they just know every toyoda is like car from sky, even if it has no airbags in 2013, lol
Despite the overprice, Toyota still make very good engine.
then please use ur intelligence and explain to us , technically how bad is is technology from toyota? u can compare to other type of transmission u like…please, we r a bunch of no brainers ,unlike u.
My point is, where are toyota fan who keep bashing other cars? I thought they are interested in technical thingy like this. And no, I don’t say anything bad about the tech, just hoping it’s not overpriced as it’s now.
it seems that in ur comment, u r also cluess or know little about in car tech, and always like to comment about “fussy” things, just like the “toyota fans ” who only know everything falls from sky.
Show you some ‘fancy’ things that you won’t know much, so that I can sell silver at platinum price.
Please don’t assume that everyone else is as limited in their knowledge as you. Some of us might get some insight from this video.
30min video to introduce/promote this engine?
Aint nobody got time for dat
These guys are worst than Toyota fanboys…
This is better than all those CVT, DSG, 9-speed transmissioni out there. With just one ICE, and 2 electric motors, Toyota manages to make do with just ONE fixed ratio. Such an elegance design.
In order to criticise 9-speed transmission, one must be able to afford 5 luxurious vehicles at any one time to quality him- or herself. Respect the 9-speed from luxurious marque, ye.
The stupid and greedy UMW toyota is still selling 1st gen toyota prius when the 2nd gen prius has been out for more than 1year. So is toyota wish.
