Welcome To
Sierra INEOS Grenadier of Irvine
Our History
Born from a desire to build a true utilitarian 4x4 with modern reliability, INEOS Automotive was founded in 2017 by British industrialist Sir Jim Ratcliffe. Dissatisfied with the disappearance of rugged, no-nonsense off-road vehicles, Ratcliffe set out to create a new kind of 4x4—one that combined classic capability with modern engineering.
The result is the INEOS Grenadier—a purpose-built off-roader inspired by legendary vehicles like the original Land Rover Defender. Developed in partnership with world-class engineering teams and tested in the planet’s harshest environments, the Grenadier is designed to go where others won’t, without compromising on comfort or durability.
Built for adventurers, workers, and everyday drivers who demand more from their vehicle, INEOS represents a bold new chapter in automotive innovation—where performance meets practicality and nothing gets in the way of the drive.
