2011 GMC Sierra Denali HD - Click above to enlarge

Not even a month ago, at the end of our post on the 2011 Ford Super Duty engine specs, we wrote: "General Motors, there's a big ass ball in your court." Someone at GM has apparently grabbed their big ass racket and said, "Oh, I got this...", then smacked the ball right back into play. The Ford's measurements 390 horsepower, 735 pound-feet of grunt. The General has just announced that its 6.6-liter Duramax turbo diesel has 397 horsepower and 765 lb-ft. of torque, a jump of 32 horsepower and 105 lb-ft. over the previous Duramax.

A closer look at the numbers does reveal some give-and-take, however. The Ford's maximum tow rating is 24,000 pounds, while GM's is 20,000 pounds. And while not exactly engine related, the Ford truck also has a higher max payload than the GM twins. Still, the RenCen pickups take the power crown, and the new Duramax is more efficient than the previous one - GM didn't put a specific mileage number to it, but claims 680 miles of highway going possible from the 36-gallon tank. You'll find GM's press release on the new engine after the jump.

In related news, GM has released the first image of its GMC Sierra Denali HD pickup, mechanical and sheetmetal twin of the Chevrolet Silverado HD. There's an additional press release after the jump for it as well.

So... anyone else want to take a swing at that even bigger ass ball?

I have the 310/605 DuraMax. My brother has the 350/650 DuraMax. 397/765 is insane.

Can I retrofit a 36-gal tank into my '04 ??

Sorry to be the pessimist, but why couldn't they have got the additional 3hp for a nice sounding 400hp? I know they can get it and they probably will sometime down the road too.

Point of correction Autoblog. That is with the heavier Ford F450, where chassis plays as an important role as the engine. GM does not have a 450 competitor. F350 tows a maximum of 18,400 lbs so technically GM twins have Ford by its diesel balls.

+1 on gorgeousness w.r.t. capability and looks. DuDi rocks.

Yes there are people who retrofit bigger tanks on older trucks.

Nevertheless it is one truck I want. Nothing beats a HD. :smilewide:

Still like the Chevy's styling better, but if I were to get a GMC anything you can bet it would be a Denali in white.
