Earlier this year, GMC released 3 images of the highly anticipated 2017 GMC Sierra Denali 2500HD trim. These fascinating photos showcased an upgraded design, which detailed a functional hood scoop. They also revealed much bolder lettering for the Duramax turbo-diesel powered option. This particular engine is highly noted for powering a large number of GMC truck models over the past ten years or so.
2017 GMC Sierra Denali 2500HD – Design and Features
The 2017 Denali trim exterior is, for the most part, identical to the 2016 model. It still features the famous cheese-grater’ grille, projection beam Xenon headlights along with the LED daytime running lights. Like the 2016 model, it comes with big chrome wheels, chrome towing mirrors together with chrome lined side-steps.
The 2017 GMC Sierra Denali 2500HD according to well-substantiated rumors, will undergo an extensive update on its interior features and accessories. This includes featuring a heated steering wheel, rear power sliding windows, ventilated and heated driver seat and front passenger seat. It will also feature bespoke interior colors and an 8” reconfigurable touchscreen display. The latter of which will integrate an intelliLink and navigation system. You should also expect Apple CarPlay’ connectivity, 4G WI-Fi hotspot as well as a wireless charging pad. As for its safety features, the 2017 Denali will come with forward collision alert, safety alert seat, lane departure warning, to name but a few.
2017 GMC Sierra Denali 2500HD – Engine Performance
The current 2016 Denali model has been made available in 2 different engine options. The first and standard one were a 6.0-liter V-8 engine capable of producing 360 hp at 5,400 rpm, and a torque of 380 pound/feet. The second alternative was a big Duramax V-8 turbo-diesel engine offering 397 hp at 3,000 rpm and a torque of 765 pound/feet at 1,600 rpm.
While most industry insiders do not expect numerous upgrades in the 2017 GMC Sierra Denali 2500HD engine, the inclusion of the hood scoop does certainly infer to an upgraded engine. More to the point, it does unequivocally signify a need for efficient engine cooling.
GMC has itself hinted that this scoop is indeed a functional one. This makes some insiders to consider it to be more of an engineering inclusion than just an aesthetic inclusion. These industry insiders believe that the 6.6-liter Duramax V-8 engine for the 2017 Denali trim will undergo some major changes.
This they say, will most likely lead to an increment in horsepower to the 397 hp range. While this truck’s torque might be destined to surpass the 765 pound/feet. On the other hand, the images GMC released did reveal a big Allison badge on the 2017 Denali’s hood.
This strongly suggests that the Duramax engine will be mated with an Allison automatic transmission. Some insiders have alluded to Allison making an upgrade of the current 6-speed heavy-duty gearbox to an 8-speed one. With all considerations in mind, such an upgrade is bound to significantly enhance the 2017 Denali’s highway fuel economy.
2017 GMC Sierra Denali 2500HD – Price and Release Date
The 2017 Sierra is currently to be had at a price of $54,590. With the various changes made on the 2017 GMC Sierra Denali 2500HD, particularly in its interior and powertrains, its price could probably be pushed higher by not more than $500. Finally, rumor has it that this truck will hit dealerships somewhere in the fall of this year.
