GM Specs New 2011 LML-Series Duramax Diesel at 397 Horsepower and 765 Pound-Feet of Torque

Scott EvansMar 10, 2010
We’ve been on pins and needles for months, ever since Ram threw down the gauntlet with its latest Heavy Duty offering. Chevy answered, albeit tentatively, last month in Chicago with promises of a class-leading diesel but no specifics. Then Ford came out swinging for the bleachers, and Chevy (and GMC) has finally answered with 397 horsepower and 765 pound-feet of torque.

If you’re keeping score, that means Chevy has won the power war, but not the towing war. While the 6.7-liter Cummins diesel under the Ram HD’s hood makes an impressive 350 horsepower and 650 pound-feet of torque and Ford’s all-new 6.7-literPower Stroke diesel pounds out a stunning 390 horsepower and 735 pound-feet of torque, Chevy’s new 6.6-liter Duramax has won the power war with an even more mind-blowing 397 horsepower and 765 pound-feet. That’s an improvement of 32 horsepower and 102 pound-feet over the last Duramax.

On the gasoline front, it’s a completely different story. Chevy’s 6.0-liter V-8 makes a respectable 360 horsepower and 380 pound-feet of torque, but Ram’s 5.7-liter V-8 makes 383 horsepower and 400 pound-feet. Here, though, Ford comes out the winner with 385 horsepower and 405 pound-feet of torque.
The order changes again when you look at capabilities. Ram falls back to third again with 5130 pounds of payload and 17,600 pounds of towing capacity. Chevy falls into seconds with 6,335 pounds of payload capacity and 20,000 pounds of towing capacity. Ford climbs back to the top of the heap with 6,520 pounds of payload and 24,400 pounds of towing. Even if you take away the top-shelf F-450 model, the F-250 still wins with 21,600 pounds of towing capacity.

So who’s the real winner here? Depends which statistic you like best. Before we declare a winner, we’ll just have to get all three together for a heavy-duty face-off. Stay tuned for that.
