2025 INEOS Automotive Grenadier vs. 2027 Rolls-Royce Cullinan

CarGurus puts the base Ineos Grenadier's starting price at $72,995 including destination, a fraction of a Rolls-Royce Cullinan, which starts well into six figures. CarsGuide says the Grenadier's price will still deter a lot of people, and that buyers into the Grenadier lifestyle have to be prepared to endure compromises and discomfort, since it is a retro-cool 4x4 with solid off-road capability rather than a luxury cruiser. The Cullinan, meanwhile, has become the most popular Rolls-Royce by far, with 80% of owners now driving themselves rather than being chauffeured.

Design. While the Grenadier is not a direct replica of a Land Rover Defender (it uses none of the original tooling or componentry), Toby Ecuyer made it clear that their mission was specifically to build a modern Defender, saying it was a 'massive shame' that the outgoing Defender was ceasing production.
