- Super Duty reclaims F-350 towing and payload leadership vs. Chevrolet Silverado 3500. When it comes to capability, Super Duty offers uncompromised choice - whether it's F-250, F-350, F-450 or F-550
- The 6.7-liter Super Duty diesel now has 20 percent better fuel economy compared with the outgoing engine based on Ford drive-cycle tests of comparably equipped 2011 Ford and 2010 Ford models
The new Power Stroke is a "clean sheet" that combines the best of proven technology with new, patented approaches backed by an extensive laboratory and real-world testing regimen to assure customer satisfaction. Benefits of the new 6.7-liter Power Stroke V8 turbocharged diesel engine include:
- First use of a compacted graphite iron (CGI) engine block in a Super Duty-class vehicle in North America; stronger than cast iron, Ford has successfully used CGI 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 horsepower.
- Unique inboard exhaust and outboard intake architecture, an automotive-industry first for a modern production diesel engine, reduces overall exhaust system volume, which leads to better throttle response for the customer; additionally, reduced exhaust system surface area minimizes heat transfer to the engine compartment and improves NVH (noise, vibration, harshness) performance.
- The new engine architecture enables easier service work for all major engine components, potentially reducing downtime. On turbocharger service, for example, the body/cab no longer has to be removed from the frame to access the turbo; also, the high-pressure fuel pump, EGR (exhaust gas recirculation) components and thermostats are directly accessible from the front of the vehicle.
- 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. This turbocharger design allows the single unit to deliver the benefits of a twin-turbocharger system in a smaller, more efficient package, combining the advantages 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 performance.
- Aluminum cylinder heads for reduced weight; the mid-deck construction with dual water jackets provides increased strength and optimal cooling; also, six head bolts, instead of four as found on other engines, help improve sealing and maintain cylinder integrity.
- Compatible up to B20 fuel, allowing greener fueling options of up to 20 percent biodiesel and 80 percent petroleum diesel.
Fuel economy is expected to improve at least another 2 percent, making the 2011 F-Series Super Duty 6.7-liter Power Stroke diesel a full 20 percent more fuel efficient than the 2010 model. The improved torque and horsepower, for example, means a customer can get to a higher gear faster and stay in it longer, both of which aid fuel economy.
Going forward, the F-350 dual-rear-wheel (DRW) model will add vehicle upgrades to bring maximum payload and maximum fifth-wheel towing to best-in-class levels. Higher-strength steel in the frame will boost the payload and towing ratings as follows:
- F-350 DRW maximum payload to 7,070 pounds, from 6,520 pounds
- F-350 DRW maximum fifth-wheel towing to 22,600 pounds, from 21,600 pounds
