The 2027 Ineos Grenadier Station Wagon Trialmaster Edition 4x4 represents the most refined and capable iteration of INEOS’ off-road-focused flagship. Purpose-built for extreme terrain and long-distance expeditions, the 2027 Trialmaster enhances performance, efficiency, and technology while staying true to the brand’s commitment to mechanical honesty and durability.
Powering the Trialmaster is an updated 3.0L turbocharged inline-six engine, now producing approximately 295 horsepower and 350 lb-ft of torque. Paired with a recalibrated 8-speed automatic transmission and a permanent all-wheel-drive system with low-range gearing, it delivers improved throttle response, stronger low-end pull, and smoother control in technical off-road conditions.
