How GM “Lied” About The Electric Car Wow… what were they thinking. In summary… it seems the claims that GM has been making for years about the design and performance of the Volt were just out and out lies. They claimed it was a serial hybrid.. meaning the gas engine was just acting as an electrical generator and that the electric motors drove the wheels. That’s a lie. They claimed it would get 230 mpg in city driving and have an initial electric range of 40 miles to cover the average commute.
