GM's 2017 New Duramax Turbo-Diesel Most Powerful to Date
The next-generation turbo-diesel 6.6-liter Duramax engine, set to debut in the 2017 Chevrolet Silverado heavy-duty and GMC Sierra heavy-duty pickup trucks, will offer more torque, power and fewer emissions than ever before. GM debuted the engine at the 2016 State Fair of Texas.
Rated at 445 horsepower at 2,850 rpm and 910 pounds-feet of torque at 1,600 rpm, the new engine is essentially all new. GM engineers have touched just about every piece of the V-8 engine from tip to tail to make it stronger and more efficient. Yes, it is still the same displacement and it still offers a 32-valve setup, but other than that, every aspect of this new engine is new and upgraded.
The more powerful Duramax (with 19 percent more torque and 12 percent more hp) has a new, stronger cast-iron block able to house a larger-diameter crankshaft with stronger connecting rods and cast-aluminum pistons. The aluminum cylinder heads now incorporate intake and exhaust passages, is stiffer, and provides much better cooling.
