Ford has announced that it's raising power levels in its all-new compression ignition engine to an astonishing 400 horsepower and 800 pounds-ft of torque through an update to the engine's software. That's an increase of 65 pounds-feet and 10 hp over the initial 390-hp, 735 pounds-feet version of the engine that was announced in February. This means that Ford has passed GM as the current holder of the most powerful diesel. Production of the new updated engines starts this week, and the owners that have the non-updated engine need not to worry, because you can simply go to your local dealership, starting Aug. 31 and have your engine software updated for free.
Now, along with more power, the 6.7L v2.0 should see improved fuel economy because the engine can shift gears faster and hold them longer. Ford says that the engine will be 2 percent more efficient that the original version by a whopping 20 percent. It's not only the best-in-class power figures, but it's also going to increase maximum towing and hauling numbers. Increased use of high-strength steel in the frame will boost the maximum payload to 7,070 pounds, up from 6,520 pounds, and max fifth-wheel towing to 22,600 pounds, up from 21,600 pounds. With power like this who wouldn't want to own and customize a 2011 Ford Super Duty 6.7L Power Stroke Diesel with performance accessories.
