2500 HD AT4X AEV Special Edition pickup

The 2026 GMC Sierra 2500 HD AT4X AEV Special Edition pickup, right hand drive, is built for adventurers and heavy-duty users who demand trail-ready capability, commanding presence, and refined comfort, offering serious off-road performance, impressive towing capacity, and a premium cabin experience. Powered by a 6.6-litre Duramax turbo-diesel V8 with 10-speed automatic transmission and four-wheel drive, it delivers approximately 470 hp (349 kW) and 975 lb-ft of torque (1,323 Nm), combining raw power for towing with smooth highway performance. The AEV Special Edition adds stamped steel bumpers, under-body skid plates, and heavy-duty off-road hardware, while the AT4X package includes a 1.5″ suspension lift with Multimatic DSSV dampers, a 4-wheel electronic locking differential, and large all-terrain tires for enhanced ground clearance, stability, and control on rugged terrain, with a maximum towing capacity of up to 18,500 lb (~8,391 kg). Inside, the crew-cab layout features premium leather seats, branded AEV touches, a large central touchscreen, digital driver cluster, and advanced driver-assist systems including trailer side-blind-zone alert, surround vision cameras, and an integrated trailering app for safety and convenience. Autogroup International completes the ISO 9001:2015-certified right hand drive conversion, preserving all OEM controls, pedals, steering, and trailer electronics, while optional upgrades such as wheel and tire packages, touring protection kits, additional lighting, snorkels, towing packages, and bespoke interior themes allow personalization. Each vehicle is fully compliant with destination-market standards, backed by a 3-year factory warranty, nationwide 24/7 roadside assistance, and a service-and-parts kit through Autogroup’s Melbourne service center.
