Ford's F-Series trucks have been king of the pickup hill for decades, but with all-new models from General Motors and Toyota, among others, the competition is getting especially fierce.

That's where the redesigned Ford F-250, F-350, and F-450 pickups come into play, with up to 650 lb.-ft. of stump-pulling torque from a new 6.4-liter Power Stroke diesel, a 6,000-lb. payload, and a tow rating maxing out at 24,000 pounds.
