I have a supercharged V-6 in my Monte Carlo (Earnhardt Racing Package) and it gets 27.6 MPG combined!
Well, it does when I’m not speeding too much!
Cubic inches is the answer.
This Chrysler actually runs on 4 cylinders most times on the highway,the other 4 kick in should you need power for leaving lights climbing hills or passing other cars. It gets fair milege because the fuel doesnt have to feed those big cylinders when they arent being used.
Stand on it and this thing sucks fuel like a vacuum.
Your car forces fuel into the cylinders when you stand on it,by using the supercharger. But you still dont have the cubes this car has and you should get better mileage.
