Ineos Automotive was formed by industrial billionaire Sir Jim Ratcliffe, after he spotted a gap in the market for an "uncompromising off-roader" in February 2017. The company's stated aim as to build "the world's purest 4x4", with explorers, farmers and off-road enthusiasts among the target audience.
The first model, the Grenadier, was born out of the gap in the market perceived with the end of production of Land Rover's original Defender. It's named after the London pub in which Ratcliffe is said to have been enjoying a pint when he had the idea.
