Ford Motor Co. released horsepower and torque ratings for the all-new diesel and gasoline engines that will power its forthcoming 2011 Super Duty models, and also released payload and towing capacities for the trucks.
The new Power Stroke diesel, a turbocharged 6.7-liter unit that was designed in-house by Ford, has a maximum torque rating of 735ft.-lb. at 1,600 rpm, and 390 horsepower at 2,800 rpm. Those figures mark improvements of 85 ft.-lb. and 40 horsepower over the outgoing, Navistar-built 6.4 liter diesel.
Ford said the new engine also delivers an average fuel economy improvement of 18 percent for pickups and up to 25 percent for chassis cab Super Duty models. The new engine is also capable of operating on B20 biodiesel, Ford said.
Ford and Navistar ended their long-standing diesel engine supply agreement last year after an acrimonious battle over engine warranty claims.
Ford is also introducing a new 6.2-liter V-8 gas engine with 385 horsepower and 405 ft.-lb. of torque – 85 more horsepower and 40 ft.-lb. of torque more than the current 5.4-liter V-8 gas engine. Ford said the engine will average 15 percent better fuel mileage that the 5.4 liter. The new engine is also compatible with E85 fuel
Maximum available towing capacity for Super Duty pickups is 24,400 pounds, and 26,400 for chassis cab models. Maximum payload is 6,520 on pickups, and 12,711 on chassis cabs.
