2025 GMC Sierra 2500HD AT4X to be sold Down Under
Tough 4x4-ute to be offered to Australia's with V8 petrol or diesel and get epic towing mightDespite being ruled out for our market by GMSV, the 2025 GMC Sierra 2500 HD AT4X full-sized pick-up is in fact coming to Australia, albeit via Autogroup International.
The Australian conversion specialist said the top-flight Sierra 2500 would have few rivals in terms of outright off-road capability (within its segment) – partly because there are very few heavy-duty trucks offered here.
Available with either a 6.6-litre V8 petrol engine or a mighty 6.6-litre Duramax turbo-diesel, it’s thought most local buyers will opt for the latter powerplant owing to its incredible 346kW/1322Nm outputs.
Combined with a 10-speed Allison automatic transmission, the huge ute can tow up to 8000kg (braked) and carry up to 1100kg.
As standard, the Australia-bound Sierra 2500 HD AT4X will ride on a factory lift kit (+38mm) and get trick Multimatic DSSV dampers, plus underbody armour, uprated control arms and steel bumpers.
Within, the standard truck’s 13.4-inch infotainment system offers Apple CarPlay and Android Auto while the 12.3-inch digital instrument cluster is supported by a vast 15-inch head-up display.
Other creature comforts include heated and ventilated leather seats, a wireless charging pad and a 12-speaker Bose premium sound system along with adaptive cruise, lane-keep assist and a 360-degree camera.
With the conversion set to take place in in Sri Lanka, the ADR-compliant Sierra 2500 HD AT4X will come with a five-year warranty and will be distributed by Melbourne-based American Vehicle Sales.
