The turbodiesel in the 2011 GMC Sierra 2500HD Denali is rated at 397 hp. - AutoWeek
EXECUTIVE EDITOR ROGER HART: While driving this monster 2011 GMC Sierra 2500HD Denali I kept thinking that this would be an outstanding work truck if you were in a business where you needed the hauling capabilities and brute force that this thing... I was thinking about all the farm trucks I drove while growing up, and while we sure could have used this kind of capability, none came close to this GMC. Then I saw the $62,000 price tag and realized this is probably more of a truck for hauling your vintage race-car trailer to the track or maybe your show ponies to the dressage competition. This is a formidable package with the Duramax and the Allison six-speed transmission. Anyone who doesn't love 765 lb-ft of torque is simply not a red-blooded American. Once you back off the throttle, the exhaust note at cruising speed is barely audible. And maybe that is the amazing thing about the Sierra 2500HD Denali. GM continues to produce damn good trucks. That's what a 2500HD pickup with a gargantuan 765 lb-ft of torque will do for you. Over the years, I've made no secret of my love for trucks, and this GMC and the Ford F-250 Super Duty are both terrific big, heavy-duty pickups, as is the Chevrolet Silverado. On acceleration, you'll hear some diesel clatter, but once up to speed, it goes away. Source: autoweek.com
