INEOS has opened US orders for the Grenadier Trialmaster X, a new range-topping trim that combines serious off-road hardware with a more comfortable interior — without asking buyers to spend hours picking individual options. Pricing starts at $85,995 for the Station Wagon and $91,395 for the Quartermaster pickup. No federal tax credit applies; INEOS dealers confirm the vehicle carries no IRA Section 30D eligibility.
Hardware that ships from the factory
Every Trialmaster X rolls off the line with front and rear locking differentials, a raised air intake (snorkel), and 17-inch wheels wearing BF Goodrich All-Terrain T/A KO3 tires. A tow ball is standard, and the gross train weight rating reaches 7 tonnes — well beyond what most truck-based SUVs legally handle. An integrated 5.5-tonne front winch is available as an option, along with a contrasting roof finish and upgraded fuel filters for regions with lower-quality fuel.
Power in the US comes exclusively from BMW's B58 3.0-liter turbocharged inline-six, producing 282 hp and 332 lb-ft of torque, paired with an 8-speed automatic. The turbodiesel B57 variant offered in Europe stays off the US order sheet, consistent with INEOS's approach since the Grenadier's original US launch.

Interior and US market context
Inside, the Trialmaster X steps up with Recaro leather seating in black or two-tone trim, heated front seats, a JBL premium audio system, and branded floor mats. Practical touches include safari windows, tinted rear glass, and a storage box integrated into the spare-tire carrier. The goal is to make the Grenadier livable on daily commutes without sacrificing the capability that defines the nameplate.
The Trialmaster X essentially fuses the existing Trialmaster (off-road focused) and Fieldmaster (comfort focused) trims into a single, pre-configured package — per PistonHeads UK, the move addresses buyer frustration with lengthy configurator sessions. In the US, roughly 302 Grenadier units sit in dealer inventory nationwide, with the Trialmaster trim averaging about 29 days on the lot — fast turnover for a niche import.
Availability
Both body styles — the 5-door Station Wagon and the Quartermaster dual-cab pickup — are available to order now across the US, UK, and more than 50 global markets, per HiConsumption. Buyers cross-shopping against the Land Rover Defender or Mercedes-Benz G-Class will find the Trialmaster X sits well below both on price while offering comparable or superior off-road specification from the factory.
