Powerhouse Under the Hood
The Defender Octa is powered by a 4.4‑litre twin‑turbocharged V8 that delivers 635 brake horsepower and 750 Nm of torque, with a launch peak of 800 Nm. The engine, originally from the BMW M5, has been extensively re‑calibrated, given its own exhaust system and cooling, to suit the Octa’s heavier weight and performance goals. This bespoke mapping ensures the power is smooth and accessible, allowing the vehicle to accelerate from 0 to 62 mph in under four seconds while maintaining the rugged character expected of a Defender.
Design and Off‑Road DNA
At first glance the Octa looks similar to a standard Defender, but subtle cues reveal its enhanced status. The wider stance, flared wheel arches, and 33‑inch all‑terrain tires give it a more purposeful stance. A redesigned front bumper improves airflow and raises the approach angle, while a revised grille feeds more air into the turbocharged engine. Bronze badges, a towing eye, and diamond‑finished titanium Octa insignia tie the aesthetic together, hinting at the vehicle’s strength and heritage.
Under the hood, the Octa’s air intake system is engineered for harsh environments. Raised carbon‑fiber intakes draw cleaner air from above the bonnet line, preventing dust ingestion during deep‑water wading or dusty off‑road runs. The vehicle can already handle a meter of water, thanks in part to this design.
Inside the Octa: Comfort Meets Performance
The interior balances ruggedness with luxury. Exposed magnesium cross‑beams and chunky grab handles remind occupants of the Defender’s off‑road pedigree, while a new 13.1‑inch touchscreen replaces the older 11.4‑inch display, offering sharper graphics and quicker touch response. Physical climate controls remain, integrated into rotary dials for a tactile feel.
Performance seats provide greater support, especially around the shoulders and legs, yet remain comfortable for long journeys. Optional body‑and‑soul seats vibrate in time with music or wellness programs, adding a subtle sensory layer. A dedicated Octa button on the steering wheel instantly switches the vehicle into a sportier mode, illuminating the Octa logo and paddle shifters in red and delivering a more aggressive driving feel.
Handling and Suspension Mastery
The Octa’s 60‑dynamic suspension system, coupled with upgraded wishbones and a dedicated Octa mode, recalibrates ABS, traction control, and throttle response for loose surfaces. This setup gives the vehicle an exceptional breadth of handling, keeping body roll, dive, and squat under control even at high speeds on uneven terrain.
The eight‑speed automatic gearbox plays a key role, keeping the engine in its optimal torque band. In everyday driving, the Octa feels smooth and unobtrusive, yet when pushed, it delivers a relentless surge of acceleration without feeling frantic. The engine’s deep, muscular rumble remains present throughout, adding to the sense of power without becoming tiring.
Practicality and Everyday Usability
Despite its performance focus, the Octa retains the Defender’s practicality. The rear seats offer generous legroom and headroom, and the flat load area expands to 1,800 L when the seats are folded. Two USB‑C ports, second‑row climate control, and heated rear seats add convenience for passengers. The boot space is generous, though the high opening requires a ramp for large pets or bulky items.
The sliding rear doors open outward, which can be a consideration in tight parking spaces. However, the vehicle’s square roofline and spacious interior make it a comfortable choice for family trips or weekend adventures. The Octa’s price starts just over £145,000, positioning it at the top of the Defender range and reflecting its advanced engineering and performance.
Closing Thoughts
The Defender Octa proves that a high‑performance SUV can still honour its off‑road roots while delivering everyday comfort and luxury. Its powerful V8, advanced suspension, and thoughtful interior make it a compelling choice for those who demand both speed and capability. While the price may be a barrier for many, the Octa offers a unique blend of engineering excellence and practical usability that sets it apart in the modern SUV landscape.
