Like a loyal canine, a thrifty sedan can be your best friend
1st Place: Toyota Prius – $1,143
The reigning champion is back. Perhaps one of the clean diesels will dethrone it, but for now the Prius costs less to operate for a year than any other family sedan. You have to get over the practical but frumpy styling. Do that, and your reward is mileage in the 40s and a roomy interior. The 1.5-liter, four-cylinder engine and electric motor produce 110 horsepower and 82 lb.-ft. of torque.
