I would like something more power efficient. A hybrid battery has something like .8 to 1kwh. At 10kw max assist, (about 13hp), It'll deplete the battery in 4 1/2 minutes. Assuming a new battery without capacity loss. That's about 4 miles on the highway, and then it'll force regen the rest of the way up a 15 mile mountain climb.
It's the stupidest thing ever. Why would you want to use what little power your tiny engine holds to charge the batteries going uphill? A supercharger might give you more power longer than sending that electricity directly to the wheels.
In addition an electric supercharger would also fill the low speed power band in accelerating from a stop.
It's a different way of getting around the lack of power in a small displacement engine while keeping it's efficient cruising capability.
I've gotten a ride in the original Smart car .6 liter turbo. That thing will run circles around my car. My IMA system doesn't even hold a candle to it.
