2025 GMC Sierra 2500HD Denali Ultimate Crew Cab Turbo Diesel in Sterling Metallic

The 2025 GMC Sierra 2500HD Denali Ultimate Crew Cab, right-hand drive, blends real heavy-duty towing capability with premium refinement in a full-size pickup built to global standards. Designed for owners who demand serious performance, luxury comfort and long-term value, it offers full factory strength in a right-hand drive configuration tailored for Australia and other right-hand drive regions.

Under the bonnet sits the 6.6-litre Duramax® turbo-diesel V8 producing 470 hp (351 kW) and 975 lb-ft (~1,322 Nm) of torque — paired with an Allison® 10-speed automatic transmission and 4-wheel drive (4WD). Towing capacity is retained at the factory left-hand drive level, delivering maximum utility, whether you’re pulling a heavy trailer for business or leisure.

Capability meets sophistication with premium suspension tuning, a high-strength frame and trailering technologies designed for demanding loads. The Crew Cab layout provides generous space for five or six passengers while the Sterling Metallic finish and Denali Ultimate detailing deliver standout presence. The truck handles both highways and remote work sites with confidence, offering performance you can depend on and comfort you’ll appreciate.

Inside, the cabin embraces luxury. Full-grain Alpine Umber leather, open-pore wood accents, illuminated power steps and a class-leading infotainment suite create a refined environment. The 13.4-inch central touchscreen and large digital driver display bring technology convenience. Advanced safety and driver-assist features provide reassurance whether you’re on a city street or towing across the countryside.

The mirror-image right-hand drive conversion is completed by Autogroup International under its ISO 9001:2015-certified engineering process. Every steering column, pedal assembly, wiring harness and dashboard control is re-engineered to OEM-equivalent specification, ensuring factory-level performance, safety and feel. This vehicle is fully engineered and documented for the Australian market and other right-hand drive markets worldwide.

Personalisation options include upgraded wheels and tyres, protection and touring packs, premium exterior finishes like the elegant Sterling Metallic, bespoke interior themes and trailer-ready accessory packages — all designed to boost capability, appearance and long-term resale confidence.

Every right-hand drive 2025 GMC Sierra 2500HD Denali Ultimate comes with a factory-backed 3-year unlimited-kilometre warranty, identical in terms to the OEM’s original coverage, plus nation-wide 24/7 roadside assistance and a service-and-parts kit, supported via Autogroup’s Melbourne service centre.
