General Motors Co.’s Chevrolet brand said Friday its 2017 Silverado heavy-duty trucks will feature a new patented air-intake system that helps to keep the engine cool even under difficult driving conditions, boosting performance.

The Detroit automaker’s biggest brand released photos Friday of the truck’s front end, which features a functional hood scoop.

The air-intake system provides 60 percent of air to the truck’s Duramax diesel engine from an inlet on the hood. The cool, dry air going to the engine helps maintain performance and keep the engine cooler during tough driving conditions. Chevy says the new system allows the engine to maintain power and the vehicle’s speed while towing. Chevy said the system has been tested in all weather scenarios from mist and downpours to snow, ice and desert dust. The system also was vetted in real-world driving conditions such as spray from semi trucks.

“The 2017 Silverado HD was engineered to provide maximum utility for our customers in even the most extreme situations,” Eric Stanczak, chief engineer for the Silverado HD, said in a statement. “While developing this all-new induction system, we considered our customers towing a maximum-weight trailer through the (more than 11,000-foot) Eisenhower Tunnel on a hot, rainy summer day.”

On Wednesday, GMC teased a photo of the 2017 Sierra HD truck — the Silverado’s sibling — and hinted a system change with the engine as it showed a function hood scoop.

The 2017 Silveardo HD and GMC Sierra HD trucks are due out this fall and GM said more details will be shared closer to launch.
