With an available fuel economy of 15 city and 18 highway, you get solid performance without sacrificing efficiency.
The interior reflects GMC's commitment to quality and convenience. The Premium Bose 7-Speaker Sound System combined with wireless Apple CarPlay and Android Auto integration keeps you connected on every drive. Heated and ventilated front seats with 10-way power adjustment and lumbar support ensure comfort during long journeys, while the heated steering wheel adds a welcome touch during cold mornings.
Safety and technology work together seamlessly in this Sierra. Adaptive cruise control with following distance indicator helps maintain safe spacing on the highway, while lane keep assist and lane departure warning provide additional confidence. The HD surround vision system with rear cross traffic braking and rear pedestrian detection offers comprehensive awareness around the truck. Ultrasonic front and rear park assist makes maneuvering easier in tight spaces.
If you tow, the ProGrade Trailering System with integrated trailer brake controller and in-vehicle trailering app transforms your hauling experience. Trailer side blind zone alert and hitch guidance remove guesswork, while the hitch view camera shows exactly what's behind you. The heavy-duty suspension and auxiliary transmission oil cooler support your towing demands.
For those seeking adventure, the X31 Off-Road and Protection Package combines hill descent control, off-road suspension, and skid plate protection. Dual exhaust and chrome wheel-to-wheel assist steps add both capability and distinctive styling. The spray-on pickup bedliner protects your truck bed from scratches and corrosion.
