The 2020 GMC Sierra AT4 delivers a unique blend of distinctive premium style, advanced technology, and off-road capability in a full-size pickup truck – but the new 2020 Sierra AT4 Off-Road Performance Package further extends AT4’s credentials and capabilities, both on and off-road.Thanks to these additions, the AT4 Off-Road Package delivers 435 horsepower and 469 lb-ft of torque - increases of 15 horsepower and 9 lb-ft of torque over a Sierra equipped with a conventional 6.2L V8 engine, and 80 horsepower and 86 lb-ft of torque over Sierra AT4 models equipped with the standard 5.3L V8. ierra AT4’s off-road abilities are fortified with specialized equipment, all purposefully engineered for venturing off the beaten trail.To start, AT4’s unique suspension design, which also incorporates Rancho monotube shock absorbers, allows it to ride two inches taller than other Sierra models, providing added ground clearance. A series of underbody skid plates help shield various chassis, cooling, and driveline components from debris, while hill descent control leverages anti-lock braking technology to help provide a smooth, controlled descent in uneven terrain without the driver needing to repeatedly push the brake pedal. Sierra AT4 also includes the new Traction Select System, which allows the driver to choose from preset drive modes that help tailor Sierra’s performance for a variety of road, terrain, or weather conditions.A standard 2-speed transfer case provides low-range gearing for challenging conditions, while a locking rear differential further helps optimize traction in slick conditions. For additional grip and traction off-road, the Sierra AT4 Off-Road Performance Package also fits 18'' Goodyear Wrangler DuraTrac mud-terrain tires to AT4’s exclusive wheels with dark chrome accents. As always, Sierra AT4 pairs its authentic capabilities with a bold, athletic look, delivered by way of distinctive finishes and modern, precise detailing. AT4’s front and rear bumpers, along with its grille surround, are painted body color. Meanwhile, AT4’s fog lamp bezels, fender badging, and exclusive grille insert – the latter boasting knurled accents - are finished in black chrome. Touches of bright red – notably on Sierra AT4’s large, vertical front recovery hooks†, further help AT4 stand out from the crowd.
Of course, smart functionality is built into Sierra AT4’s distinctive form at every turn. Sierra AT4’s cargo box, for instance, offers best-in-class cargo volume, and also offers an available 120-volt electric power outlet to power tools, lights, or other accessories. Available GearOn rails within the box allow for bike racks, kayak carriers, and other accessories to be quickly and easily installed or adjusted.†
Performance is a key ingredient to every Sierra AT4, and the Sierra AT4 Off-Road Performance Package takes the AT4’s abilities a step further. Not only does the AT4 Off-Road Performance Package include the 6.2L V8 with Dynamic Fuel Management and a ten speed automatic transmission, it also includes a specially-designed Cold Air Intake and Performance Exhaust System. Both the intake and exhaust system are designed to not only optimize performance, but also deliver an unmistakably sporty exhaust note.
Loading or unloading cargo is also easier, thanks to Sierra AT4’s standard MultiPro Tailgate. This world's first design can be used in six different configurations, allowing both easier access to the box itself along with enhanced second-tier loading and load-stop solutions. Dropping both the primary and inner tailgates and unfolding the lower step make climbing into the bed – even with AT4’s elevated ride height – simple and straightforward.
The half-ton GMC pickup can tow up to 12,200 pounds and support a payload up to 2240 pounds, when properly equipped.
