2026 GMC Sierra
2500 HD AT4X AEV Special Edition pickup

2026 GMC Sierra 2500 HD AT4X AEV Special Edition pickup, right hand drive, designed for adventurers and heavy-duty users who demand trail-ready capability, commanding presence and refined comfort. It suits owners who want the confidence of serious off-road equipment, the towing muscle for robust loads, and a cabin that feels premium every day.

This truck is powered by the 6.6-litre Duramax turbo-diesel V8 paired with a 10-speed automatic transmission and four-wheel drive, yielding approximately 470 hp (349 kW) and 975 lb-ft of torque (1 323 Nm). Exact 0–100 km/h time and top speed are TBC. With this drivetrain matched to the AT4X AEV upgrades, you get both raw grunt for towing and smooth performance when cruising highways.

Capability and practicality are built in. The AEV Special Edition adds stamped steel front and rear bumpers, under-body skid plates and heavy-duty off-road hardware for added protection and durability. The AT4X package includes a factory-installed 1.5″ suspension lift with Multimatic DSSV dampers, a 4-wheel electronic locking differential, and large all-terrain tyres on bespoke wheels — benefits include added ground clearance for rugged tracks, assured stability when towing or loaded, and improved control on rough roads. Maximum towing capacity is up to 18 500 lb (~8 391 kg) in similar configurations; exact Australian-spec figure is TBC.

Inside you’ll find a luxe crew-cab layout with premium leather seats, branded AEV touches and a tech-rich environment. A large central touchscreen and digital driver cluster ensure effortless connectivity, while driver-assist systems such as trailer side-blind-zone alert, surround vision cameras and an integrated trailering app add safety assurance and convenience whether you’re towing long-distances or navigating tight sites.

Autogroup International completes the mirror-image right hand drive conversion using its ISO 9001:2015-certified process. The conversion preserves all original manufacturer controls and systems, including steering-column input, pedals, shifter and trailer electronics, ensuring OEM-equivalent functionality for right hand drive markets. Specific checks on the trailer-brake controller interface and off-road creature-comfort switches deliver trust and real usability.

Options and personalisation deepen the appeal. The AEV Special Edition already includes off-road steel bumpers, directional recovery points, and branded wheels. Further choices include upgraded wheel and tyre packages for stance and grip, touring protection kits, additional lighting or snorkel accessories, towing packages with heavy-duty hitch and brake controllers, and bespoke interior themes to tailor the cabin. These upgrades enhance both capability and resale confidence.

Every right hand drive Sierra 2500 HD AT4X AEV Special Edition is engineered for destination-market compliance and comes with a factory-backed 3-year warranty with conditions identical to the OEM’s original warranty. It is supported by nationwide 24/7 roadside assistance and a service-and-parts kit via Autogroup’s Melbourne service centre.
