Not to mention the increased reliability from the lesser number of mechanical parts used, lower maintenance, more legroom and floor flatness... the list goes on.
It’s the battery and / or chemistry and part that needs to see massive improvement.
One of the big changes we’ll see in electric cars once battery technology matures is that instead of a space-wasting engine compartment in the front or rear of the vehicle, the entire drivetrain can be tucked on the bottom of the car. This frees up more interior space, which means by 2025-2030 an electric car will be subcompact sized externally but compact sized internally.
