Something different Building for MPG.

that is the key right there. these new cars are efficent as compaired to the old cars, but these new cars weigh about 1000 to 1500 more pounds so the gain in mpg is lost by the weight. when you take these old cars and put modern engines w/ overdrives in them ,their gas mpg is better in most cases than anything running on the road today. reason is most of our cars weigh in at around 3100 to 3200 pounds vs. 4000 to 4300 pounds
