Land Rover "All New Defender Octa (OCTA)" is the top trim of the Defender 110. The Octa-exclusive logo, derived from the word for diamond, is engraved in various places, giving the exterior a distinctive feel. The gasoline engine with mild hybrid (MHEV) technology delivers a maximum output of 635 horsepower and sprints from zero to 100 kph in 4 seconds, the most powerful performance among Defenders. However, the price is higher by at least tens of millions of won, and in some cases by more than 100 million won.
Octa retains the Defender's signature boxy silhouette, but its color and design are unique. The standard color is Petra Copper with a golden hue, a shade not easily found on ordinary vehicles. The wheel housings (the exterior body panels where the wheels are mounted) fitted with dedicated off-road tires are also large.
The body measures 5,003 mm in length, 2,064 mm in width, 1,995 mm in height, with a 3,023 mm wheelbase (distance between the front and rear axles). Compared with the regular model (length 5,018 mm, width 1,996 mm, height 1,967 mm, wheelbase 3,022 mm), it is wider and taller. Minimum ground clearance (gap between the ground and the vehicle floor) is 246 mm, up 28 mm.
The interior feels comfortable and upscale. The seats with long headrests are generous and comfortable. The integration with the sound system is also notable. As the first application in the Defender, the so-called "Body and Soul Seat" lets you feel vibrations from the backrest along with the sound and rhythm when music is played.
The vehicle generally drives smoothly and quietly regardless of road conditions. While opening and closing the windows during driving for comparison, a significant portion of external noise such as wind noise (wind hitting the body) was blocked. Pressing the accelerator delivered strong force that pushed the massive body forward. It crested steep uphill sections with ease, though the engine note became somewhat rough.
The vehicle can climb even steeper hills than the regular model (approach angle 35 degrees), with a maximum approach angle of 40 degrees. It exited cornering sections nimbly. According to Land Rover, Octa is the first Defender to adopt the hydraulic interlinked 6D Dynamics suspension, which minimizes body roll (side-to-side sway) and pitching (front-to-back sway). There was almost no forward dive under hard braking.
Although it is a sport utility vehicle (SUV), its driving performance is similar to that of a sports car. Equipped with an eight-cylinder 4.4-liter (L) gasoline engine with MHEV technology, the vehicle delivers a maximum output of 635 horsepower and peak torque of 76.5 kg·m. It is on par with the Aston Martin Vantage S (680 horsepower) and the Ferrari Amalfi (640 horsepower). Octa takes 4 seconds to accelerate from a standstill to 100 kph (zero to 100).
However, with a price exceeding 200 million won and low fuel efficiency, maintenance costs are likely to be high. The Defender Octa is priced at 224.97 million won, and the Octa Edition One with added convenience features starts at 242.47 million won. Octa's official certified fuel economy is 7 km per liter (L) on the combined cycle, with 8.1 km on highways and 6.3 km in urban sections.
