Want to bring a new vehicle the market, but have never done it before? You're probably going to need some help. And that's just what Ineos Automotive has recruited – from another manufacturer you've probably never heard of, even if its products you definitely have.

Ineos Automotive is an offshoot of a chemical company that's now focused on bringing a rough-and-tumble off-roader called the Grenadier to market. And the company whose resources and expertise it's solicited is Magna Steyr – the Canadian-owned Austrian contract manufacturer and engineering firm that builds, among other vehicles, the Mercedes-Benz G-Class, and always has.

The Ineos Grenadier project, for those unfamiliar, stemmed from an aborted plan to continue manufacturing the old Defender after Land Rover discontinued its production ahead of the new model's arrival. When that didn't pan out, Ineos broke out on its own to develop its own off-road SUV, signing a deal with BMW to supply the engines and Magna's powertrain division to help develop the chassis and suspension. Now it's expanded that partnership to Magna Steyr to help prepare it for production. But this won't be the first time that Magna Steyr will work on an SUV, of course.

Aside from the G-Class, the facility in Graz, Austria, developed the Steyr-Daimler-Puch Pinzgauer 4x4 back in 1969, and currently builds the E-Pace and I-Pace for Jaguar. It also previously handled assembly of the Mercedes M-Class (precursor of today's GLE), Mini Countryman, BMW X3, and two generations of Jeep Grand Cherokee – to say nothing of all the lower-slung passenger cars it's built for countless automakers throughout the years. This time, however, while Magna Steyr is helping with the Grenadier's development, it won't be building it: that will take place at Bridgend, in the same country of Wales where Aston Martin (another former client of Magna's) is building the new DBX.
