Yes, the Volt is a direct descendent of the EV1. You can certainly see the resemblance in many of the concepts, but he Volt is so much better.

How about that portable charger? Coast Down button? Driver unlock code?

Some features disappeared or totally gone. For ex. charger was faster.

The T shaped battery stayed. ;)

Yes, that interesting. The 6.6 kW EV1 charge station would add 90 miles in 3.5 hours. The 2019 Volt with the 7.2 kW option will charge the equivalent of 90 miles in 3.9 hours.

The EV1 is extremely aerodynamically efficient, even compared to a gen 2 Volt.


I'm curious as to how efficient the motor was. I've noticed pure BEVs tend to be a little more efficient than PHEVs. I haven't found the engineering reason for that, but it stays pretty consistent, so there must be a clear design decision being made or a design constraint.

I would guess it has something to do with the transmission. While the Volt doesn't have a transmission like an ICE car, it does have to have clutches and other moving parts that have to be turned whereas a pure BEV can basically connect the motor shaft directly to the wheels so it only has to turn the wheels. There's probably a tiny bit of energy loss in a PHEV with the motor(s) having to turn over parts other than the wheels.

Also, the Volt has active temperature management for the battery which lowers the mpge in hot weather, but that means the battery lasts longer. And a bigger battery may have better efficiency at higher output levels.
