Ineos Automotive has revealed a hydrogen-fuel-cell variant of its Grenadier 4×4 at the Goodwood Festival of Speed, intended to prove its commitment to lower-carbon fuels.
It trades the conventional Ineos Grenadier’s choice of BMW-supplied combustion engines for BMW’s latest hydrogen-fuel-cell stack. Ineos told Autocar that this holds 5kg of the fuel, giving a range of around 200km (124 miles) between fill-ups. The firm said it would target 550km (342 miles) in an eventual production model.
The demonstrator uses three electric motors – one up front and one on each rear wheel – producing a claimed 5900lb ft of torque (at the motors) in total. Ineos said it would aim to include an additional motor at the front on a production model, targeting a combined output of 13,276lb ft. However, Ineos would not be drawn on the motors’ power output, saying instead that “the key is torque” for an off-roader.

According to Ineos, the set-up’s torque-vectoring capabilities provide improved manoeuvrability on the rough stuff, with a tighter turning circle. Such advantages have already been capitalised on in other electrically powered 4x4s. The Rivian R1 and the upcoming Mercedes-Benz EQG can both perform ‘tank turns’, able to rotate at a complete standstill. The GMC Hummer EV, meanwhile, can ‘crab walk’ – driving side to side using vectoring alone, without steering input.
Switching to a fuel-cell powertrain has not compromised the Grenadier’s capabilities, said Ineos, with the new variant also having completed the same Schöckl mountain pass in Austria that was integral to the development of the ICE model.
Ineos’s decision to choose hydrogen over battery-electric is rooted in its chemicals business, because the firm produces 400,000 tonnes of hydrogen annually. Should the Grenadier FCEV receive the production go-ahead – a likelihood, given the firm already notes its ‘power bulge’ bonnet would not be present on a production model, and has divulged target specifications – it would effectively create a virtuous circle for Ineos, boosting demand for its hydrogen.
