The right-hand drive 2026 GMC Sierra 1500 AT4X in Summit White with Obsidian Rush interior is where serious off-road kit meets everyday refinement. Converted by Autogroup International to mirror-image right-hand drive, it keeps factory ergonomics, safety systems and tech exactly where they belong—just on the correct side of the cabin for our markets. With an engineering-validated 4,500 kg braked towing capacity, it works as hard as it looks.
Power comes from the flagship 6.2-litre EcoTec3 V8 (420 hp / 313 kW, 460 lb-ft / 624 Nm) paired to a 10-speed automatic. Real-world pace is confident—0–100 km/h ~6.1 s—with an electronically limited ~177 km/h top speed (tyre and condition dependent). The AT4X chassis adds a factory 2″ lift, Multimatic DSSV dampers, front and rear e-locking differentials, skid plates and a 2-speed Autotrac transfer case for control when the road runs out.
Inside, the AT4X is genuinely premium: full-grain leather in Obsidian Rush, heated and ventilated seating, a 13.4″ central display with Google built-in, 12.3″ driver cluster, 15″ head-up display, and Bose 12-speaker audio. Trailering aids and surround vision reduce the workload on long days; thoughtful touches like the rear-seat storage package and wireless charging make it easy to live with.
