As Ford's biggest SUV, the Expedition can accommodate up to eight passengers and tow 9200 pounds (4173 kilos) when properly equipped. The Expedition features an aluminum body and borrows several mechanical components from the Ford F-150. Its only engine is a twin-turbo, 3.5-litre V6 that produces 375 horsepower, or 400 in the Platinum trim level. A 10-speed automatic gearbox channels the power to all four wheels.
