Regarding the "butt dyno", if you ever look into building an EV one of the first things you'll find that you must choose between acceleration and top speed, between either of those and range, and between all of that and the weight of it.

Ergo focusing on performance kills the range. In the Volt GM is trying to get around this issue by installing a "range extending petrol engine". This adds tremendous cost and weight to the vehicle... all just for the butt dyno effect.

It is a self defeating idea.
