The Ineos Grenadier Quartermaster is a body-on-frame pickup truck variant of the Ineos Grenadier 4x4, produced from 2023 to the present. It shares the Grenadier's ladder-frame construction and mechanicals, distinguishing itself with an extended wheelbase and an open cargo bed, making it one of the few purpose-built truck-bed off-roaders in its class. The Quartermaster is powered by BMW-sourced turbocharged six-cylinder petrol and diesel engines and retains the Grenadier's permanent four-wheel-drive system with locking differentials front and rear. The model is positioned toward utility and overlanding use, appealing to buyers who need both serious off-road capability and practical load-carrying capacity.
