According to Voltstats.net the average Chevrolet Volt driver does about 75% of their driving on electric, and 25% on gasoline. I have a Volt and for me it is more like 99% on electric and 1% on gas.
So the Volt has an EPA rating of 38 miles EV range. Lets imagine that it had 60 miles EV range. I bet the numbers would shift to where the average driver got 85% EV. What about 80 miles EV range? 100 miles EV range? I suspect at 100 miles range you would finally hit that average of 99% all EV driving and that 1% on gas. The thing is, at this point you can continue to increase the battery range and you still have diminishing returns. That’s because the 1% remaining usually ends up being road trips. This is already the case with my Volt. that 1% of gas usage is when I need to drive from Dallas to Houston, or Austin.
