2011 Chevrolet Duramax Diesel Makes 397 hp and 765 lb-ft, Bests Ford and Ram

The heavy-duty truck wars have been building to a boil over the past few months. Ram released its latest offering late last year; Chevrolet promised best-in-class power last month with no specifics; and Ford unleashed a monster new diesel on the truck world. Now, Chevrolet has finally opened the floodgates and released the final power numbers for its new diesel: a mind-boggling 397 horsepower and 765 pound-feet of torque.

If you’re keeping score, that means Chevy (and by extension, GMC) 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 wins 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 of torque 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 with 5130 pounds of payload and 17,600 pounds of towing capacity. GM comes in second with 6335 pounds of payload and 20,000 pounds of towing capacity. Ford climbs back to the top of the heap with 6520 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.
