check offers Defender has unveiled the Dakar D7X-R, a competition-focused evolution of the Defender OCTA built to comply with the FIA's new Stock class regulations for 2026. Regulations prohibit major changes to the production vehicle, meaning the D7X-R retains OCTA's D7x aluminum body architecture, transmission and driveline layout. It is powered by the same 4.4-litre twin-turbo V8, which should remain mechanically unchanged, and runs on FIA-compliant sustainable fuel.
Desert-inspired 'GeoPalette' design
Visually, the D7X-R features a new “Geopalette” livery shaped by desert tones of sand, stone and earth, contrasted by a hint of aqua representing rare desert water. The scheme reflects the raw, elemental atmosphere of rally-raid competition.

Production roots with motorsport-ready upgrades
Despite the limitations of the stock class, Defender Rally has added targeted enhancements for the Dakar and W2RC rounds. The D7X-R shares its bodyshell with the Defender 110, but integrates a 550-litre rear fuel tank for longer stages, some over 800 km. A full competition roll cage is fitted to protect the crew.
The ride height has been raised, the track width has increased by 60 mm, and 35-inch tires have been fitted for better off-road performance. Revised front and rear bodywork increases approach and departure angles while maintaining OCTA design cues. Extended protection under the floor has inspired revised sills and trimmed door panels.
Bilstein-developed suspension and improved cooling
The SUV retains the core suspension geometry of the OCTA, but adopts rally-spec dampers co-developed with Bilstein, which feature a single coil-over at the front and twin dampers at the rear to manage harsh impacts and the additional fuel load.
Cooling has been significantly upgraded for desert conditions: a large radiator replaces the road car's three radiators, assisted by four 12V fans. A redesigned bonnet improves heat extraction, and a particulate filter protects the engine from sand. Roof-mounted light pods and cabin air intakes have also been added.

Refined driveline, upgraded brakes and new 'Flight Mode'
The eight-speed gearbox has been retained, but paired with a shorter final drive for stronger low-speed torque delivery. The braking system has been replaced with vented discs and multi-piston callipers. A new “Flight Mode” adjusts torque while the vehicle is airborne, helping to stabilize landings and protect the driveline.
Rally ready cockpit
Inside, the D7X-R features FIA-regulated navigation, a head-up display and customized motorsport seats. Supported by integrated hydraulic jacks, three spare wheels, tools and necessary spares are stored within the roll cage.
After more than 6,000 km of testing, Defender Rally will enter the D7X-R in its first competitive appearance at the 2026 Dakar Rally, starting on January 3 in Saudi Arabia.
