El motor turbodiésel rediseñado le inyecta más potencia a la Silverado HD 2017

  • g+1

Offering more horsepower and torque than before, the redesigned Duramax 6.6L V-8 turbo-diesel engine available with the 2017 Silverado HD gives drivers more confidence every time they hook up their trailer.

"Silverado HD gives you confidence," said Jeff Luke, Chevrolet Chief Engineer, Full-Size and Midsize Trucks. "And confidence gives you the best towing experience."

The new Duramax 6.6L features an all-new, stronger cylinder block and rotating assembly, as well as a new control system. The modifications helped the engine achieve an SAE-certified 445 horsepower (332 kW) and 910 lb.-ft. of torque (1,234 Nm) - a 19 percent increase over the current Duramax 6.6L.

"The new Duramax delivers impressive output, but what customers will appreciate the most is an improved driving experience," said Eric Stanczak, Silverado chief engineer. "It delivers quicker acceleration, more confidence when trailering up a steep grade, better engine braking on descent, and more refined noise levels cruising on the highway."

The redesigned engine also features a new, patent-pending vehicle air intake system, which drives cool, dry air into the engine for sustained performance during difficult conditions. Cooler air helps the engine run better under load, especially in conditions where engine and transmission temperatures can rise quickly. This allows the Duramax to maintain more power and vehicle speed when trailering in the toughest conditions.

"The Duramax diesel has forged a bond with truck customers based on trust and capability," said Dan Nicholson, vice-president, Global Propulsion Systems. "The new Duramax takes those traits to higher levels, making the 2017 Silverado HD one of the most refined on the highway."
