I never knew a Vette could get such good milage. Good going.
It's not an unrealistic issue. If mass needs to move, it takes enregy to move the mass. The Vette I had weighed about 3200 lbs. Even though it had a 5 litre V-8, it takes "X" joules of energy to move that mass. On the other hand, when I shot the car out of the shoot, 0-60 in 6 seconds, then that was a poor use of energy. Bottom-line, fast cars are NOT necearilly fuel monger, unless you drive them in that manner.
