GMC Sierra
From their home-grown truck range, the Sierra remains a popular model. The 2500 HD All-Terrain X is a recent introduction and offers a choice of a 6.0-litre petrol V8 or a 6.6-litre Duramax turbo-diesel delivering nearly 450 PS and over 1,200 Nm. You also get 275-sec proper MT-rated off-road rubber.
