Weber Auto channel has the best EV drive trian videos on YouTube. They just posted a new video on Honda hybrid drive train:
An excellent video. He really likes the design. I always liked how few parts there were for the functionality. Makes it very cost effective. In fact, the other day I was thinking, what if they separated the systems, putting the main EV drive motor on the rear axle. Leave the generator and ICE on the front axle, and let it power the front drive as needed for on demand AWD or quick acceleration bursts.
