The 2026 INEOS Grenadier is a body-on-frame off-road SUV available as a Station Wagon or Quartermaster pickup. It competes in the segment with vehicles such as the Toyota Land Cruiser, Land Rover Defender 110, and Jeep Wrangler Rubicon. For 2026, the model receives updates including revised steering geometry for improved on- and off-road handling, enhanced safety systems, improved climate control, and the addition of a Black Edition trim with darkened exterior elements. The powertrain consists of a BMW-sourced 3.0-liter turbocharged inline-six gasoline engine rated at 282 horsepower and 332 pound-feet of torque, paired with a ZF eight-speed automatic transmission, permanent four-wheel drive featuring a two-speed transfer case, center differential lock, and solid beam axles.
The infotainment system uses the Grenadier Connected platform with a 12.3-inch central touchscreen for navigation, media, and vehicle information including tire pressures and pitch/roll angles. It supports wireless Apple CarPlay, Android Auto, and off-road Pathfinder functions for waypoints, track logging, and GPX file imports, controlled via touchscreen, steering wheel, or rotary controller. Updates for 2026 include advanced driver assistance systems with Intelligent Speed Assist featuring a homescreen shortcut for audible alert deactivation, refined climate control for better temperature management, and additions such as Lane Departure Warning and Automatic Emergency Braking to meet regulations. There are no changes to screen size, major new driver aids beyond compliance, or powertrain electrification. Connectivity relies on Grenadier Connected for phone integration and Bluetooth, with no dedicated mobile app or over-the-air updates available.
