2011 Ford Super Duty power, towing specs released
Heavy duty truck lovers have been waiting for these figures for a while, so let's just cut to the main course. The 2011 Ford Super Duty can be had with two engines: the 6.2-liter gasoline-powered V8 found in the upgraded SVT Raptor, which puts out 385 horsepower and 405 pound-feet of torque, or an all-new, Ford-designed 6.7-liter turbo-diesel V8 producing 390 hp and a pavement pummeling 735 lb-ft of twist (at 1,600 rpm).
The latter engine in the F450 is able to tow some 24,400 pounds and has a maximum payload of 4,920 pounds. The F350, which is the closest competitor to the Chevrolet, GMC or Ram equivalent, comes to the fight with 21,600 pounds of towing capacity and 6,520 pounds of payload (if you're curious why the F450's maxium payload is less than the F350's, check out this explanation half-way down the page). Each engine is mated to a 6R140 heavy-duty TorqShift six-speed automatic transmission.

In addition to hardware-based improvements, the new transmission features enhanced Tow Haul mode with integrated engine exhaust braking and SelectShift Automatic capability, which includes Progressive Range Select and a manual mode, allowing customers to select the gear to suit their needs.
The new TorqShift transmission also enables the first application of Live Drive PTO (Power Take Off) in a Super Duty-class vehicle. On 2011 Super Duty diesels with the PTO prep option, the PTO output gear is linked through the torque converter to the engine crankshaft. This allows the transmission to power auxiliary equipment such as snowplows, aerial lifts, tow truck lifts, cement mixers or dump trucks. The power is available any time the engine is running.
Pioneered on agricultural applications, the Live Drive feature is particularly useful when mobile PTO function is required during start-stop operations, such as salt spreading or snow plowing. "A fully functional Live Drive mobile PTO will allow Super Duty customers to take full advantage of the equipment on their trucks," said Al Bruck, 6R140 transmission engineering manager.
Best-in-class towing and payload; new towing options
Putting all that power to work is what defines Super Duty. The 2011 Super Duty builds on its best-in-class towing and payload capability and also offers more towing options from inside the bed. New is the first-ever factory-installed and warranted fifth wheel and gooseneck substructure directly attached to the frame.
"Our system is factory-installed and comes with a limited warranty from Ford. The electrical connection is mounted in the side of the bed wall, providing a clean installation," said Peter Frantzeskakis, vehicle engineering manager.
Particularly noteworthy are productivity enhancements to the F-450 pickup to benefit the heaviest-duty trailer tow customers. Unneeded weight was shed, helping to improve fuel economy and top speed. Even with these changes, the F-450 Super Duty pickup maintains its class-leading gross combined weight rating of 33,000 pounds.
Addition of Trailer Sway Control leads safety enhancements
Ford's lauded Trailer Sway Control (TSC) system joins the Super Duty lineup, giving those customers segment-first capability. TSC is integrated with AdvanceTrac® with Roll Stability Control™, which now is standard on all single rear wheel (SRW) configurations.
The AdvanceTrac control module uses additional software to monitor the truck's motion when a trailer is attached. TSC can determine from the yaw motion of the truck if the trailer is swaying and take measures – such as applying precise braking or reducing engine torque – to help reduce the trailer sway.
For further peace of mind, the available integrated trailer brake controller, factory-installed and covered by a Ford limited warranty, offers smoother and safer operation due to its ability to interface with multiple vehicle systems.
Normal braking is proportional to driver brake pressure for smooth brake stops at all speeds. If the vehicle's Anti-lock Brake System (ABS) is engaged, the special trailer brake kicks in to minimize the potential for trailer wheel lockup. In Super Duty trucks with Trailer Brake Control towing trailers with electric brakes, the Ford system can, during a sway event, also apply brakes to the trailer to help stabilize it.
