Thanks for the insights. This is interesting. This is why I will end up keeping an eye on it. I'm interested to see how they managed to scale down yet retain the effeciency. They've replaced a transmission and drive train with a generator, power transmission, electric motors and batteries. Maybe a 10x increase in weight. I'm curios if this is going to be a success or not.

My guess is that it's not that significant of an increase in weight. They're removing everything including the axles, and putting in their own. Guestimating based on the video, I'd say each motor+axle weights similarly to a transmission, the engine is a lot smaller but add the generator, that's probably a wash. Batteries, they're planning to be small and cheap (because they have a generator), so lets guess 20kwh, so maybe 300lbs in batteries. Fuel tank stays, drive shaft is out. So, basically a total increase of one transmission (150lbs) and 300lbs worth of batteries, so 450lbs in all. Definitely heavier, but I think it's a far cry from 10x. 2x would be my guess, which seems well within the realm of reasonability
