0 By

Looking for a heavy-duty truck that blends raw power, off-road capability, and upscale comfort? Meet the 2023 GMC Sierra 2500HD 4×4 Crew Cab AT4, a bold and capable pickup built to tackle Alberta’s toughest jobs and wildest adventures. Available now at Red Deer Motors, this truck is tailor-made for drivers who demand durability without sacrificing refinement.

Bold Design with an Off-Road Edge

The 2023 Sierra 2500HD AT4 stands out with its aggressive styling, featuring a black chrome grille, red recovery hooks, and unique AT4 badging. Riding on 18-inch machined aluminum wheels with all-terrain tires and a factory-installed 2-inch lift, the AT4 offers increased ground clearance and a commanding road presence.

The 4×4 Crew Cab configuration provides ample room for five adults, while the spray-on bedliner, cargo tie-downs, and available MultiPro Tailgate make this truck as practical as it is good-looking.

Powertrain Built for Heavy Lifting

Under the hood, the 2023 Sierra 2500HD AT4 is powered by a 6.6L V8 gas engine, generating 401 horsepower and 464 lb-ft of torque. Paired with a smooth-shifting 6-speed automatic transmission, this powertrain is built to haul, tow, and perform in the harshest conditions.

Prefer diesel? Some models also offer the Duramax® 6.6L Turbo-Diesel V8 with 445 hp and a staggering 910 lb-ft of torque – perfect for serious towing.

When equipped properly, this truck can tow up to 18,500 lbs, making it ideal for trailers, RVs, and equipment haulers.

Off-Road Capability that Means Business

What sets the AT4 trim apart is its off-road-focused features. With Rancho® monotube shocks, skid plates, an off-road suspension, and a two-speed Autotrac transfer case, this Sierra is ready for trails, backroads, and rugged work sites.

The AT4 also includes GMC’s hill descent control and traction select system, allowing you to adjust performance for changing terrain – from mud and gravel to snow and ice.

Refined Interior with Smart Tech

Inside, the AT4 combines durability with luxury. Premium materials, all-weather floor liners, and heated and ventilated front bucket seats ensure you’re comfortable year-round. The Crew Cab layout offers generous rear legroom and under-seat storage for tools or gear.

  • 8-inch GMC Infotainment System with Apple CarPlay® & Android Auto™
