The Mustang Source - Ford Mustang Forums - 2011 Super Duty Getting A Boost

The Ford built 6.7-liter Power Stroke® V8 turbo diesel, already praised by customers and journalists for its power, quietness, and fuel economy will raise the bar even higher. The result of additional durability and capability testing, the new 6.7L Power Stroke® diesel will now be rated at best-in-class 800 lb.-ft. of torque and 400 horsepower, an increase of 65 lb.-ft. of torque and 10 horsepower compared to when the all-new Ford-engineered and Ford-built engine went on sale earlier this year. The 6.7L Power Stroke® diesel's best-in-class fuel economy will be improved as well – now 20% better than the outgoing pickup models (vs. 18% at launch). Production at Kentucky Truck Plant with these performance upgrades will begin on August 5th.
Starting with production on August 9th, one of the heavy haulers in the 2011 Ford F-Series Super Duty lineup – the F-350 Dual Rear Wheel (DRW) - will add vehicle upgrades that will 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
