The battle for ultimate bragging rights in the Heavy Duty pickup arena has taken a major turn with Ford's announcement that it was upgrading the output figures of the 6.7-liter Power Stroke turbdiesel V8 in it 2011 F-Series Super Duty pickups to new class-leading levels. The mid-season changes, which come strictly as a result of software modifications to the engine's electronic control module, will bump horsepower from 390 to 400 and up peak torque from 735 to 800 lb-ft. Those new 2011 figures marginally surpass the 397 horses and 765 lb.-ft. of torque created by GM's just-redone 6.6-liter DuraMax turbodiesel V8 that recently debuted in the 2011 Chevrolet Silverado 2500 HD and GMC Sierra 2500 HD pickups. The best news for F-Series aficionados is that Ford will perform this upgrading on any 2011 Super Duty models already purchased at no charge in a process that can be done at any authorized dealer in about 30 minutes.
Details of this Super Duty enhancement program were made public at the CAR (Center for Automotive Research) Management Briefing Seminars being held this week in Traverse City, Michigan. Ford says that the upgrading process will commence by the end of August and continue for the next 12 months and that all 2011 Super Duty diesel pickups currently in dealer inventory will automatically get the fix prior to sale.
"We know that durability and reliability is uppermost in the minds of our Super Duty customers, along with torque and horsepower, so we took a conservative approach that ensured that the new Power Stroke would be absolutely bulletproof while delivering significantly improved power," said Chris Brewer, chief engineer of the 2011 Super Duty. Brewer also indicated that the changes are expected to add about two percent to the fuel economy, which will make 2011 F-Series Power Stroke engine a full 20 percent more fuel efficient than its 2010 counterpart. Beyond that, the engine's extra muscle will help boost maximum payload on F-350 Super Duty dually models from 6,520 lbs. to a 7,070 lbs. and raise their fifth-wheel max towing spec from 21,600 to 22,600 lbs.
"We want to take care of our loyal, F-Series Super Duty pickup owners who supported us when we debuted our all-new Ford-designed, Ford-engineered and Ford-built Power Stroke earlier this year and reward them by offering them the same best-in-class torque, horsepower and fuel economy our new customers are receiving right now," said Barb Samardzich, Ford Motor Company's vice president of powertrain.
