Remember our story on the 2017 GMC Sierra Denali 2500 HD? A couple of days later, General Motors decided to take the wraps off the 2017 Chevrolet Silverado 2500 HD. Care to guess what the two trucks have in common as far as styling is concerned?
You’re right, it’s the hood scoop. Compared to the way GMC put it in its release, Chevrolet makes it clear that what you’re looking at isn’t an add-on scoop, but part of an intake system with a ram-air supercharging effect. The inlet at the front of the hood provides 60 percent of the air needed by the 6.6-liter Duramax V8.
Speaking of the turbo diesel, Chevrolet has yet to detail anything about the output of the Duramax engine. As we’ve explained in the 2017 GMC Sierra Denali 2500 HD story, General Motors is feeling a bit left behind by the 2016 Ram 2500 and the 2017 Ford F-250 as far as torque and tow rating are concerned.
Instead of speculating, let’s focus on what else that revised intake system of the 3/4-ton workhorse. According to Chevrolet, “the air filter housing also draws 40 percent additional air from a dry location in one of the front fenders.” This air blends with the one from the chrome-accented hood inlet before being funneled into the turbo diesel V8, a bulletproof solution in the event the scoop is blocked.
“The 2017 Silverado HD was engineered to provide maximum utility for our customers in even the most extreme situations,” assures Eric Stanczak, the chief engineer of the Chevrolet Silverado HD family of pickup trucks. “While developing this all-new induction system, we considered our customers towing a maximum-weight trailer through the Eisenhower Tunnel on a hot, rainy summer day.” An air/water separator ensures only dry air is drawn into the combustion chambers.
Kevin Dunn, a man whose business card reads ‘global vehicle performance for splash engineering,’ explains that the air intake "works well with water droplets of all sizes.” And yes, that also includes mist-like spray.
