Take on demanding jobs, changing Ontario weather and weekend adventures in this new 2026 GMC Sierra 1500 AT4 Crew Cab Short Box 4-Wheel Drive, available at MacFarlane Chevrolet Buick GMC in Petrolia, Ontario.

The Sierra 1500 AT4 combines professional-grade capability with premium comfort and authentic off-road engineering. Its four-wheel-drive system, two-speed transfer case, factory suspension lift, off-road-tuned suspension and protective underbody equipment provide additional confidence on snow-covered roads, gravel trails, muddy worksites and uneven terrain.

Bold AT4 styling helps this truck stand out with a rugged grille design, distinctive exterior accents, red recovery hooks and an athletic, elevated stance. The practical short cargo box provides versatile space for tools, equipment, recreational gear and everyday hauling, while the spacious Crew Cab gives rear-seat passengers generous room to travel comfortably.

Inside, the unique Jet Black interior with Kalahari accents delivers a refined and unmistakably AT4 atmosphere. Heated and ventilated front seating, a heated steering wheel, modern digital displays and advanced infotainment technology help make every drive more comfortable and connected.

The large touchscreen infotainment system provides convenient access to navigation, entertainment and compatible smartphone features through Apple CarPlay and Android Auto. A configurable digital Driver Information Centre keeps important driving and vehicle information clearly visible.
