Getting a nation back on the road to prosperity is hard work. Rebuilding and repairing a battered infrastructure takes the right tools. As much as we like small cars, there are some jobs they just can’t do. Sometimes, you need a super capable, super tough truck to ‘getter done.” Sometimes you need a Super Duty.

Ford Super Duty customers expect and demand capability from the best-selling heavy-duty truck in America. For most Super Duty owners, it’s the core asset of their business. Day after day, year after year, it’s expected to deliver results in the most demanding situations. No nonsense. And never any excuses.

Ford’s F-Series has been the best-selling line of trucks in the U.S. for 33 straight years. With class-leading torque, horsepower, fuel economy and towing and payload capability, the new Super Duty further underscores Ford’s Built Ford Tough legacy.

New diesel and gasoline engines deliver improved torque, horsepower, fuel economy

For 2011, Super Duty features both all-new diesel and gasoline engines that are mated to a new transmission. The new 6.7-liter Power Stroke V-8 turbocharged diesel was designed, engineered and built by a Ford team dedicated solely to delivering this class-leading diesel to the next-generation Super Duty to enable continued best-in-class towing and payload.

The result: The new Power Stroke pumps out a best-in-class 735 ft.-lb. of torque at 1,600 rpm and 390 horsepower at 2,800 rpm, enabling the 2011 Super Duty’s class-leading towing capability of 24,400 pounds. The 2011 Super Duty also has class-leading payload capability at 6,520 pounds.

Benefits of the new 6.7-liter Power Stroke diesel engine:

• First use of a compacted graphite iron (CGI) engine block in a Super Duty-class vehicle in North America; CGI is stronger than cast iron, and Ford successfully has used the material in engine blocks in products around the world. The block structure was optimized for reduced weight and maximum strength to meet the demands of higher torque and more horsepower, and enable class-leading fuel economy.


• Unique inboard exhaust and outboard intake architecture, an automotive-industry first for a modern production diesel, reduces overall exhaust system volume, which leads to better throttle response; a reduced exhaust system surface area minimizes heat transfer to the engine compartment and improves NVH (noise, vibration and harshness).


• The turbocharger features an industry-first dual-sided compressor wheel that works in a single housing. The unit is uniquely center-mounted on a pedestal low in the back of the valley for improved NVH. The design allows the single unit to deliver the advantages of a twin-turbocharger system in a smaller, more efficient package, combining the benefits of a small turbocharger (faster response) and a large turbocharger (ability to compress and force more air into the engine for more power) in one unit.


• The high-pressure fuel system injects fuel at more than 29,000 psi. The system delivers up to five injection events per cylinder per cycle using eight-hole piezo injectors to spray fuel into the piston bowl. The direct-injection system is calibrated and phased for optimum power, fuel efficiency and NVH.


• Aluminum cylinder heads for reduced weight; the mid-deck construction with dual water jackets provides increased strength and optimal cooling; six-head bolts, instead of four as found on other engines, help improve sealing and maintain cylinder integrity even with the higher firing pressures.


• Compatible up to B20 fuel, allowing greener fueling options of up to 20 percent biodiesel and 80 percent petroleum diesel.

The engine and aftertreatment system for the 6.7-liter Power Stroke V-8 turbocharged diesel powertrain ably meets the new, more stringent 2010 federal emissions requirements for nitrogen oxides (NOx), which have to be lowered by approximately 80 percent, making this the cleanest Super Duty diesel ever.

New gasoline engine delivers class-leading power and fuel economy as well

Ford tapped into a bit of its proud racing heritage to create the new 6.2-liter V-8 gasoline engine, which uses big-bore architecture to produce best-in-class torque, horsepower and fuel economy. The new gasoline engine delivers 405 ft.-lb. of torque (at 4,500 rpm) and 385 horsepower (at 5,500 rpm) on regular gasoline. The new V-8 also is E85 compatible.

These numbers represent an increase of 40 ft.-lb. of torque and 85 horsepower over the outgoing 5.4-liter V-8. The V-8’s large bore (102 millimeters) allows for larger intake and exhaust valves for improved engine breathing, and the short stroke (95 millimeters) allows higher engine speed for increased horsepower.

Benefits of the new 6.2-liter V-8 gasoline engine include:

• SOHC valvetrain with roller-rocker shafts: The single overhead camshaft (SOHC) per cylinder head design results in a stiff valvetrain that allows optimized camshaft lift profiles and results in great low-speed torque. The roller-rocker shafts allow valve angles to be splayed, resulting in optimized intake and exhaust port layout for better breathing.


• Dual-equal variable cam timing: Intake and exhaust valve opening and closing events are phased at the same time to optimize fuel economy and performance throughout the engine speed range and throttle positions.


• Two spark plugs per cylinder: Due to the large bore size, two spark plugs per cylinder are used to more efficiently burn the fuel-air mixture in the combustion chamber, enabling better fuel economy and increased engine torque. The twin plugs also help the engine maintain a smooth, stable idle.


• Dual knock sensors: A knock sensor on each bank of cylinders of the V-8 engine allows the spark timing of each cylinder to be individually optimized real-time, throughout the engine speed range. The engine learns the optimum timing via an adaptive algorithm.


• Better engine crankcase “breathing” and efficiency: Significant development work and computer-aided engineering optimized the cylinder block for more efficient airflow in the crankcase as the pistons move up and down in the bores, resulting in improved torque at higher engine speeds. Piston-cooling jets squirt oil on the underside of the pistons to keep the piston crowns cool under extreme operating conditions. The cooling jets also allow for a higher compression ratio for better engine efficiency and faster engine oil warm-up on cold starts, also improving fuel economy.

New TorqShift transmission harnesses and manages the power; Live Drive PTO available

The all-new 6R140 heavy-duty TorqShift six-speed automatic transmission was designed to manage the high low-end torque produced by the new diesel engine. The same basic transmission also is mated to the new gasoline engine, giving customers of either engine the ability to efficiently get the increased torque and horsepower to the ground. Engineered for greater efficiency and fuel economy, improvements include refined architecture to provide relatively low clutch speeds, which results in lower drag losses, and optimized fluid levels and drainback to reduce churning of fluid while also providing superior lubrication.

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.
