2017 Chevrolet Silverado 2500HD revealed
Here’s a first official look at the revised 2017 Chevrolet Silverado 2500HD pickup fitted with the optional Duramax Turbo-Diesel V8 engine. Like the 2017 GMC Sierra Denali 2500HD that showed its new face earlier this week, the ¾-ton heavy-duty version of Chevy’s full-size hauler is largely a visual carryover but also boasts a new functional hood scoop when packing the optional 6.7-liter Duramax engine.
Like GMC, Chevrolet remains equally mum when it comes to sharing a number of pertinent details on this Duramax-spec truck, including whether the engine will still be backed by the current 6-speed Allison automatic transmission. However, the automaker did confirm the new scoop works with a patented intake system that “drives cool, dry air into the engine for sustained performance and cooler engine temperatures during difficult driving conditions.” Exactly how much this new ram-air induction setup might bump the engine’s current 397 horsepower and 765 lb-ft of torque remains to be seen, but rumor has it we could see the pony count move close to 425 and the critical peak twist units top the 800 mark. If that proves true, expect maximum tow ratings for the Duramax-powered 2017 Chevrolet Silverado 2500HD to rise as well.
Engineered to excel in extremes
As for operational efficacy, Eric Stanczak, chief engineer, Silverado HD notes the 2017 2500HD “was engineered to provide maximum utility for our customers in even the most extreme situations.” The new induction system provides 60 percent of the intake air via the hood scoop and sends it to the Duramax Turbo-Diesel engine at ambient temperature, which is lower than the underhood temp. This allows the engine to run cooler while developing full power and maintaining vehicle speed even under max load.
We’ll be bringing you more details about the 2017 Chevrolet Silverado 2500HD pickup with the Duramax Turbo-Diesel as well as with the standard 6.0-liter gasoline V8 engine when it is launched later this year.
