The 2016 Ford Super Duty trucks are offered in F-250, F-350 and F-450 models, designating progressively higher tow and weight ratings. Compared to light-duty, full-size trucks, like the F-150, the Super Duty models have a stronger structure, along with heavy-duty components throughout and a powertrain lineup chosen for sheer pulling and hauling ability. Ford Super Duty trim levels include XL, XLT, Lariat, King Ranch and Platinum. Throughout the lineup, there's a choice of two different engines -- either a 385-horsepower, 6.2L gasoline V8, or a 440-horsepower 6.7L Power Stroke turbo diesel engine. The gasoline engine is also compatible with E85 (85-percent ethanol) and can be equipped for propane or compressed natural gas, which makes it attractive for fleet use. In any practical use, the diesel engine, with its mammoth 860 pound-feet of torque, comes out far ahead of the gas engine's 405 pound-feet. No matter which engine, the Super Duty trucks come with a heavy-duty 6-speed SelectShift automatic transmission. F-350 and F-450 models get a reinforced frame and hitch system compared to F-250 models. Both the F-350 and F-450 are also offered in a dual-rear-wheel configuration for better stability with heavy loads. F-350 models can tow up to 26,500 pounds with either a conventional bumper hitch or a fifth-wheel hitch, while F-450s will tow up to 31,200 pounds. All single-rear-wheel models of the Super Duty trucks come with electronic stability control plus trailer sway control and hill start assist to help with standing starts on steep uphill slopes. Anti-lock brakes are also included and an integrated trailer brake controller is available. Integrated exhaust braking -- like that of big rigs -- is on the options list with the diesel, while Hill Descent Control also helps on slippery downhills, even when towing. Big PowerScope trailer-tow mirrors are also available. Ford's SYNC with MyFord Touch in-dash multimedia system is standard on Lariat, King Ranch, and Platinum models. It features an 8-inch high-resolution touchscreen display, with access to climate controls, phone, entertainment and navigation features, along with voice control. The display also shows the view from the rear backup camera. The options list for the F-Series Super Duty Trucks isn't as comfort- and luxury-oriented as that of the F-150, though trucks at the top of the range can be ordered as luxuriously as desired. Some innovative specialized features, such as a Ford Work Solutions Crew Chief system for fleets and a Cable Lock security system for equipment, are geared toward those who use the Super Duty for serious work.
