<div style="text-align: center;"><strong><em><small>2011 GMC Sierra Denali HD - Click above to enlarge</small></em></strong></div>
<br />
Not even a month ago, at the end of our post on the <a href="http://www.autoblog.com/2010/02/25/2011-ford-super-duty-power-towing-specs-released/">2011 Ford Super Duty engine</a> specs, we wrote: "General Motors, there's a big ass ball in your court." Someone at <a href="http://www.autoblog.com/make/gm">GM</a> has apparently grabbed their big ass racket and said, "Oh, I got this...", then smacked the ball right back into play. The <a href="http://www.autoblog.com/make/ford">Ford</a>'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.<br />
<br />
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. <br />
<br />
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.<br />
<br />
So... anyone else want to take a swing at that even bigger ass ball?<br />
