How many miles per gallon will the Chevy Volt get?
A bit of a trick question. For the first 40 miles it will get infinite mpg, because no gas will be burned. When the generator starts, the car will get an equivalent of up to 50 mpg thereafter. One can calculate the average mpg per for any length drive starting with a full battery: Total MPG = 50xM/(M-40). GM has announced the car will get 230 MPG for the average city driver over time assuming nightly full recharges.
