The 2026 GMC Sierra 1500 AT4X in right hand drive is engineered for enthusiasts who demand premium off-road capability, elevated design and everyday usability. It suits drivers who want sophisticated refinement, superior road and trail confidence, and the practicality of a high-end full-size pickup tailored for RHD markets.
Under the bonnet this AT4X features a potent engine choice including the 6.2-litre V8 petrol or optionally the 3.0-litre Duramax™ turbo-diesel with a 10-speed automatic transmission and four-wheel drive. The diesel variant produces around 305 hp (228 kW) and 495 lb-ft (~672 Nm) of torque. With this drivetrain you gain strong real-world performance, refined cruising ability and trustworthy off-road power. Exact 0–100 km/h and top speed figures for the Australian-spec right hand drive version are TBC.
The capability is evident. As an AT4X model, it comes equipped with a 2-inch factory lift, off-road tuned suspension, underbody skid-plates and all-terrain tyres—giving you ground clearance, handling precision and confidence on rough surfaces. Towing capacity for the Sierra 1500 line reaches up to ~9,000 lb (~4,082 kg) in comparable spec; Australian specification is TBC. Payload capacity and exact off-road geometry figures are also TBC.
Inside you’ll enjoy a premium cabin with seating for five, full leather upholstery, unique trim accents specific to AT4X and a large infotainment display paired with digital driver instrumentation. Technology convenience is built in with smartphone integration, premium sound system and extensive driver-assist features such as trailer-side blind-zone alert and adaptive cruise—delivering both luxury and safety assurance.
The conversion for right hand drive is handled by Autogroup International using an ISO 9001:2015-certified process. Every component—from steering column and pedal box to wiring harnesses and infotainment systems—is re-engineered to OEM-equivalent functionality, so the vehicle retains factory precision in a right hand drive configuration. Trailer electronics and off-road controls are likewise refined to ensure destination-market readiness.
Options and personalisation abound. Alongside the AT4X standard off-road hardware you can upgrade wheels and tyre packages, choose appearance or protection packs, select interior themes or add bed accessories, and configure towing enhancements—each tailored to maximise capability, style and resale confidence.
This right hand drive 2026 GMC Sierra 1500 AT4X is engineered and documented for the Australian market and comes with a factory-backed 3-year unlimited-kilometre warranty, with conditions identical to the OEM’s original warranty. It also includes nationwide 24/7 roadside assistance and a service-and-parts kit supported via Autogroup’s Melbourne service centre.
