Powered by a 5.3L V8 engine and equipped with a 4x4 drivetrain, this AT4 trim is designed to handle tough terrains with ease, while maintaining the refined luxury that GMC is known for.
Bold Exterior Built for Adventure
The 2021 Sierra 1500 AT4 is built to turn heads with its 20-inch alloy wheels and aggressive LED headlights and taillights that provide a sharp, modern look. The MultiPro Tailgate offers versatility for loading and unloading, perfect for both work and weekend adventures. Equipped with Rancho off-road suspension and skid plates, this truck is ready to tackle any road from Summerstown Station to Churchill Heights with confidence.
A Luxurious and Comfortable Interior
Step inside the AT4 and you'll experience premium leather-appointed seating that’s both heated and ventilated, ensuring comfort in any weather. The dual-zone automatic climate control keeps the cabin temperature perfect for both driver and passengers, and the heated steering wheel adds a touch of luxury during those cold Ontario winters. Whether you're cruising through Tyotown or making long trips to Alexandria, the premium floor mats ensure the cabin stays clean and inviting.
Advanced Safety and Technology for Peace of Mind
Safety is a top priority in the 2021 Sierra 1500 AT4. Advanced features like Forward Collision Alert and Lane Keep Assist with Lane Departure Warning help you stay aware on the road. The HD Surround Vision and Rear Cross Traffic Alert offer enhanced visibility, making tight maneuvers around Cornwall’s busy streets a breeze. Whether parking in Embrun or backing out in Moose Creek, the Front and Rear Park Assist adds another layer of convenience and safety.
Superior Convenience and Entertainment Features
The Bose premium audio system and navigation system make every drive more enjoyable, whether you're heading to South Lancaster or exploring the trails near Morrisburg. The wireless charging and seamless Apple CarPlay and Android Auto integration ensure you stay connected on the go, while the remote start system makes warming up your truck on chilly mornings hassle-free.
Why the Sierra 1500 AT4 Stands Out from the Competition
When compared to rivals like the Ford F-150 and Ram 1500, the 2021 GMC Sierra 1500 AT4 offers superior off-road capabilities, thanks to its advanced suspension and durable build. While competitors may offer similar powertrains, the combination of luxury features and off-road prowess gives the Sierra AT4 an edge, especially for drivers in Williamstown, St. Andrews West, and beyond who need both performance and comfort.
