New mileage rules: Pay more for cars, less at pump - Yahoo! News Imagine the options with this $20,000 car you move 200,000 units of a year. Its a 3400 lb family sedan with 3 engine choices. A 180horse 32 mpg 2.2Liter 4 banger no one buys. A 250horse 26mpg 3.3Liter V6 which is the most popular choice, and a 399 Horse 22mpgTurbo 6 cylinder which is the "face car" of the model. What will it take to make this car get 35mpg? Not much. Make a 140 horse 4 cylinder your main model. Your company probably already has this engine in production for your economy gas getter. Don't say 140 horse cars aren't acceptable. I'm not the oldest one here and I remember cars in the 80's doing 70mph just fine. Where does the increased cost come from?
