30 gallon gas tank?
Wouldnt a 2000 mile range and 70 mpg equal about a 30 gallon fuel tank? That seems exceptionally large. Again, Smart Planet needs to do some editing.
PS There are several reasons for relatively poor gas mileage (I had a 80 VW diesel that consistently got 50 mpg) Some of those reasons for poor gas mileage are government mandated, including emission mandates, fuel mandates (ethanol) and safety mandates (impact protection, 5 mph bumpers), some are customer comfort mandates, (AC, power windows, etc)
