Fuel economy: Why you're not getting the mpg you expect
With fuel prices rising, Consumer Reports tested actual mpg rates for new cars and compared them with the manufacturers' mpg ratings. They found shortfalls in 90 percent of the vehicles they tested, including hybrids. In some models they found shortfalls of 50 percent. Manufacturers use prototype vehicles to determine mpg ratings and do not drive them the way actual consumers do.
