In February, the specs on Ford's 6.7-liter Power Stroke turbo-diesel V8 were announced: 390 horsepower and 735 pound-feet of torque. A month later, General Motors laid out the specs on its 6.6-liter Duramax turbo-diesel: 397 hp and 765 lb-ft. According to PickupTrucks.com, the Duramax could be shoved to the corner again later this year, when a high-output Super Duty blows out the footlights with 400 hp and 800 – or more – lb-ft of twisting gumption.
As is well known by now, Ford and Navistar have parted ways and the Blue Oval is developing diesel engines in-house to replace the PowerStroke lumps still being used. Slated to appear in Ford's trucks by 2011, the new oil burner code-named Scorpion is a 6.7-liter V8 with a host of innovations, some of them seemingly borrowed from cross-town rival GM.
