2026 GMC Sierra 2500 HD AT4X AEV Special Edition pickup, right hand drive, is the ultimate expression of strength, refinement and all-terrain mastery. It’s built for serious adventurers, professionals and enthusiasts who want heavy-duty towing power and genuine off-road capability wrapped in luxury. Engineered for Australia and other right hand drive markets, it blends premium comfort with battlefield-tested hardware.
At its core is the choice of two powerful engines: the 6.6-litre Duramax turbo-diesel V8 generating 470 hp (349 kW) and 975 lb-ft (1,322 Nm) of torque, or a 6.6-litre petrol V8 delivering 401 hp (299 kW) and 629 Nm. Both are paired with a 10-speed automatic transmission and advanced four-wheel drive system for consistent performance under any condition. These engines provide commanding towing and acceleration, with diesel models offering exceptional torque for heavy hauling.
Capability and practicality are where the AT4X AEV Special Edition stands apart. The AEV (American Expedition Vehicles) upgrades include stamped steel front and rear bumpers, heavy-duty recovery points, five hot-stamped boron steel skid plates, and Multimatic DSSV dampers for unrivalled off-road control. A factory lift enhances clearance, while all-terrain tyres mounted on AEV Salta wheels deliver traction across rock, sand or mud. Maximum towing capacity reaches approximately 8,400 kg (TBC for Australian specification), supported by reinforced axles and a fully boxed high-strength steel frame. This setup gives both rugged off-road composure and confident highway stability.
Inside, the Sierra 2500 HD AT4X AEV Special Edition offers premium comfort for five passengers. The cabin features full-grain leather upholstery with AEV-embroidered headrests, heated and ventilated front seats, and contrast stitching that complements its rugged exterior. A 13.4-inch touchscreen infotainment display with Google Built-In, a 12.3-inch digital driver cluster, and a premium audio system provide technology convenience and connected comfort. Safety assurance comes from adaptive cruise control, lane-keeping assist, trailer blind-spot monitoring and a 360-degree camera system designed for large-vehicle manoeuvring.

Each addition enhances the Sierra’s versatility and resale confidence while ensuring owners can tailor their truck to their preferred look and purpose.
