2011 Ford Super Duty pickup – Click above for high-res image gallery
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.
The revamped 6.6-liter Duramax V8 engine will go into production in April 2010 and the current Duramax, which doesn't meet emissions requirements that go into effect January 1, 2010, will cease production the day before the new year begins. In the interim, GM will be retooling the factory and won't be producing any of the engines to go in the Chevy Silverado and GMC Sierra.
New emissions standards in 2010 will make things too stringent for GM's Duramax diesel, in its current form, to make the grade. To help its prize student pass the looming tests, GM is investing $69 million in its DMAX plant (a joint venture diesel engine factory in Moraine, Ohio) for plant renovations and new machinery and tooling.
