Previously, GMC was given the green light to drop the first official photos of the 2017 GMC Sierra HD Denali, featuring a massive hood scoop. Surely, it’s hiding a major powertrain upgrade.
Now, Chevrolet has had its chance, too. Here are the first photos of the 2017 Chevrolet Silverado HD. We merely say “photos” because there aren’t really technical specs accompanying the reveal. All we know is the same, massive hood scoop has been tacked on to the hood to likely cool down a reworked Duramax diesel engine.
Chevrolet states the hood treatment involves a patented air intake system, which drives dry, cool air into the engine to keep things cool when things get heated. 60-percent of air routed to the engine now comes from the intake system.
The benefits of the new system are cut and dry: cooler air means the engine can operate at optimum power, especially when the engine and transmission are under load.
“The 2017 Silverado HD was engineered to provide maximum utility for our customers in even the most extreme situations,” said Eric Stanczak, chief engineer, Silverado HD. “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.”
The 2017 Silverado HD also ensures moist, wet air isn’t entering the system either. Part of the patented intake system includes a air/water separator, to ensure only combustion-enhancing dry air is drawn into the engine. The air charge enters an expansion chamber containing a sharp, 180-degree turn on its way to the air filter housing.
That creates a velocity change that causes humidity or mist to form larger, heavier droplets that are flung centrifugally against the outside wall of the housing. Science!
We wish we had additional information for you, dear reader, but Chevrolet is keeping their lips locked over what this fancy, new air intake system is cooling down. One thing is nearly certain, though: there’s more power in the 2017 Silverado HD’s future.
