How much better has the average MPG for general motors been in the past few years?

    It really depends on the vehicle you’re refering to, whether it’s hybrid, biofuel, etc. They Volt will give you 93 miles per gallon equivalent on electric and 60 mpg for gas-electric. A 1999 Chevie Tahoe gets 13 mpg in the city, 15 mpg with diesel and 17 mpg in the city. I hope this answer doesn’t complicate your question.
