Combined mpg: 13 mpg city/highway
Base price: $43,630 Ford ( F) designed this massive pickup truck primarily for off-road driving -- which is what you should stick to if you buy one, because it offers everyday users terrible fuel efficiency. Whether you buy the two-door SuperCab or four-door SuperCrew version, the Raptor gets just 11 mpg/city and 16 mpg/highway. That works out to 13 mpg combined city/highway -- the worst rating for any mainstream 2013 sold in America. The Raptor has such low mpg because it's loaded with all sorts of inefficient off-road equipment, from a 411-horsepower V-8 engine to heavy skid plates to protect the truck's undercarriage from rough terrain. "With the SVT Raptor, Ford took a standard F-150 and turned it into a super-off-road pickup truck," Reed says. "You can essentially go tearing across the landscape at high speeds with one and trample everything in your path."
