What’s the latest scoop on the next iteration of HD trucks from GM? Check it out! Here is the first look at the upcoming 2017 GMC Sierra HD. The truck pictured here is a 2500 HD with the popular Denali package. We have waited a long time to get any official information or images about the 2017 heavy duty trucks from GM.
The company released the three images you see here and said “the 2017 Sierra Denali 2500HD features a functional hood scoop design hinting at what is beneath its bold new appearance.” We now know that the hood scoop is functional, and we know what it looks like. However, we don’t have any specifications on the engine, transmission, towing, or hauling capabilities.
We have captured several 2017 GMC HD prototypes testing in the wild over the last two years. And we have anticipated a functional hood scoop, based on the camouflaged hood. We have also confirmed that a turbo-diesel has been tested in the Colorado Rocky Mountains. We have even seen the Diesel Exhaust Fluid (DEF) tank on the passenger.
So what really lurks under the ever more imposing hood? My guess is that it is an updated 6.6-liter Duramax turbo-diesel V8 engine. It would make sense that GM is targeting 900 lb-ft of torque or more, in order to compete head-to-head with the high-output version of Ram 3500 HD and Ford F-350 Super Duty trucks. However, GM has played it conservative with quoted power figures on the previous versions of its HD trucks. However, the trusted 6-speed Allison automatic transmission should handle the extra output without too many changes.
Does this truck use a “ram air” intake system to stuff more air into the turbo-diesel? Is the scoop only there to provide additional cooling? Can the hood scoop also be connected to the gasoline V8 offering in the truck? Will GM continue to use the 6.0-liter Vortec V8 or go with an updated version of the 6.2-liter V8? Will the Chevy Silverado HD lineup receive the same engine upgrades and a hood scoop? GM will answer these and many other questions over the next several months.
