Ineos Automotive has introduced a new top-trim version of its retro-styled off-roader, unveiling the Grenadier Trialmaster X, calling it the “most capable and best-equipped” model yet.Ineos says the Trialmaster X blends the hardcore off-road hardware of the existing Trialmaster with a lot of the luxury and comfort features found on the more road-focused Fieldmaster model. Among its premium features are heated leather-trimmed Recaro seats, higher-grade carpeting, safari roof windows, and an expanded suite of cameras and driver-assistance technology.“Building on the significant enhancements introduced for 2026, Trialmaster X is the pinnacle all-rounder,” Ineos Automotive CEO Lynn Calder said in the company’s launch announcement. “The ultimate combination of off-road toughness, premium day-to-day comfort and intrepid spirit.”Ineos Grenadier Trialmaster XAs with every Grenadier, the Trialmaster X is a body-on-frame truck with permanent four-wheel drive, locking front and rear differentials, BFGoodrich all-terrain tires, and a raised air intake designed for deep-water crossings. Power comes from BMW-sourced turbocharged inline-six gasoline or diesel engines paired with an eight-speed automatic transmission, and it comes in either SUV or Quartermaster pickup configurations. Ineos hopes to extend the appeal of the Grenadier brand beyond its hardcore in-the-know buyers, pitching itself at the end of the market that values off-road bona fides but perhaps cares more about its suburban profile. In this regard, the Trialmaster X is targeting shoppers of such vehicles as the Land Rover Defender, Mercedes-Benz G-Class, and high-end Jeep Wrangler variants.Since launching the Grenadier in 2022, Ineos has expanded its lineup with a slew of special editions and constant updates. The 2026 models received revised steering, updated safety systems and cabin improvements aimed at making the rugged SUV easier to live with day-to-day. Pricing for the Trialmaster X starts at $85,995 for the SUV and $91,395 for the Quartermaster pickup.
