The 2018 Sierra All Mountain concept takes GMC’s signature bold design and engineering excellence to new heights, adding tank-like tracks that help it navigate rugged, snow-covered terrain.
Built on a Sierra 2500HD Denali 4WD Crew Cab platform, the epitome of GMC’s strength and design, the All Mountain concept stands ready to tackle steep slopes and extreme weather conditions. It combines the power (445hp, 1233Nm) of the 6.6-litre turbo-diesel V8 engine and first-class interior appointments of the Sierra 2500HD Denali and adds enhanced capability and features through concept technology and GMC accessories.
The special features of the GMC one-off include Mattracks 150 Series Tracks with GMC Red finish,
bodyside graphics, wheel-well and underbody LED lights, Thule snowboard racks, Kicker amplifier, Rigid E-Series 30-Inch Light Bar, Advantage soft roll-up tonneau cover and an Allison 1000 6-speed automatic transmission.
