The 2017 Silverado HD To Offer The Redesigned Duramax Engine

On Thursday, Chevrolet announced that the redesigned Duramax 6.6L V-6 turbo-diesel engine will be offered on the 2017 Silverado HD. With a 19 percent increase in max torque over the current Duramax 6.6L, the engine now produces 445 horsepower and 910 lb.-ft of torque. This is the best engine of its kind yet.

In addition to the power updates, the turbo-diesel’s performance is even quieter and smoother than before. At idle, the engine noise has been reduced a whopping 38 percent.

“With nearly 2 million sold over the past 15 years, customers have forged a bond with Duramax diesel based on trust and capability,” stated Dan Nicholson, vice president, Global Propulsion Systems. “The new Duramax takes those traits to higher levels.”

The new Duramax will share the bore and stroke dimension of the current Duramax 6.6L, but will be using an entirely new GM-developed control system. Despite this new control system, the engine’s signature low-rpm torque production has not changed, still offering 90 percent of peak torque at 1,550 rpm and sustaining through 2,850 rpm.

“Nearly everything about the Duramax is new, designed to produce more torque at a lower rpm and more confidence when trailering or hauling,” said Gary Arvan, chief engineer. “You’ll also notice the refinement improvements the moment you start the engine, and appreciate them as you cruise quietly down the highway - with or without a trailer.”

The 2017 Silverado HD will be headed to Chuck Hutton Chevy in Memphis, TN shortly, so be on the lookout!
