Ineos has introduced a new Grenadier trim called the Trialmaster X, a 2026 model that builds on the regular Trialmaster and sharpens the brand’s off-road pitch with more standard equipment and a lower price. The new version is offered as both a Station Wagon and a Quartermaster, and it arrives with hardware and cabin upgrades that push it closer to the top of the lineup without asking buyers to pay more than the equivalent regular model.
The Trialmaster X adds locking front and rear differentials, BF Goodrich KO3 all-terrain tires, an intake snorkel and an upgraded alternator. It also comes standard with 17-inch alloy wheels, a storage compartment in the spare wheel and the towing package. Inside, the changes include heated Recaro seats trimmed in leather instead of cloth, a better sound system, carpeted floor mats, pop-up safari windows and tinted rear windows. A small badge at the base of the windshield identifies the trim.
For buyers trying to decide whether the extra equipment is worth it, the numbers do most of the talking. The 2026 Grenadier Trialmaster X Station Wagon has a base MSRP of $85,995, or $87,990 with the $1,995 destination charge. The Trialmaster X Quartermaster starts at $91,395 and reaches $93,390 with destination. A configured regular Trialmaster with equivalent equipment came to $88,695 before destination and $90,690 after it, making the Trialmaster X $2,700 cheaper in like-for-like form.
That price break matters because Ineos has spent years marketing the Grenadier Station Wagon and Quartermaster as harder-use off-road vehicles than many SUVs, especially the current Land Rover Defender. The company even ran an ad campaign showing a clean Defender beside an Ineos covered in dirt, a not-so-subtle way of saying where it believes the real trail credibility lies. The Trialmaster is already the most capable trim on offer, and the Trialmaster X leans into that reputation rather than trying to reinvent it.
The new trim is available in Scottish White, Devil Red, Donny Grey and Magic Mushroom, with only Donny Grey offered as a metallic finish. All four colors can be paired with a contrasting black or white roof. That still leaves the regular Trialmaster with a broader palette, including 11 different colors plus contrast roof options, so the new X is not the most customizable version of the vehicle. It is, however, the more heavily equipped one.
Under the hood, the Trialmaster X keeps the same turbocharged 3.0-liter straight-six from BMW, rated at 282 horsepower and 332 pound-feet of torque. Power goes through an eight-speed automatic and a two-speed transfer case for four-wheel drive, which means the trim’s additions are aimed at making the Grenadier easier to live with and better prepared for rough terrain, not changing the underlying formula. For shoppers who want the most capable setup with a stronger standard-spec list and a lower equivalent price, the new Trialmaster X is the clearest answer Ineos has given so far.
