This is something that I've never figured out. Does adding a 1000 pounds to a car reduce FE by 1/2? Engine are cleaner and more fuel efficient then ever. It appears that they have more than double the HP thus the big decrease in FE. Seem to me that they could lower the HP and work with the gearing and get the numbers back where they should be.
