When Land Rover unveiled the latest generation of the Defender, many enthusiasts wondered how the company could top the already fantastic performance of the V8 models. The answer, of course, was to add even more speed. Enter the 2026 Land Rover Defender Octa, a vehicle that combines the rugged capability of the Defender with a BMW-sourced 4.4-liter twin-turbo V-8 engine, delivering a staggering 626 horsepower and 590 pound-feet of torque. This engine transforms the Defender from a capable all-terrain vehicle into a true high-performance SUV.
The Octa is not just about straight-line speed. Land Rover’s Special Vehicle Operations, under the direction of Jamal Hameedi (who was instrumental in developing both the Ford GT and F-150 Raptor), has fitted this beast with a hydraulically linked suspension to combat pitch and roll, wide fender flares to increase the vehicle’s width by 2.7 inches, and a quicker steering rack. The suspension arms and links have been lengthened, and the front seats feature beefier bolsters for added support. The vehicle sits 1.1 inches higher and is fitted with 33-inch tires, either all-terrain or all-season. It also features a towing package, making it one of the most capable off-roaders with the heart of a supercar.
This impressive list of upgrades comes at a price. The 2026 Land Rover Defender Octa has a starting price of $153,850, making it one of the most expensive SUVs on the market. Its only real competition in the ultra-luxury, aerodynamics-be-damned segment is the $196,900 Mercedes-AMG G63.
The Octa certainly looks the part of a performance SUV. The matte finish on this test car’s Petra Copper paint comes from a $5,155 self-healing wrap—a smart investment for a vehicle that is designed to be driven hard on and off the road. The visual gravitas of the Octa is undeniable, with a design that is both imposing and elegant. It has the visual gravitas of a villain charismatic enough that it becomes the protagonist in the sequel. This test car’s Petra Copper paint gets its matte appearance from a $5,155 self-healing wrap—probably worth it, given the width of this trail-ready rig.
Performance Overview: A BMW-Sourced Rocket
The addition of the BMW V-8 engine completely changes the character of the Defender. This engine is no stranger to Land Rover, having been used in the Range Rover and Range Rover Sport Autobiography models. It is a powerful and smooth engine that provides ample acceleration for all driving situations.
The Octa’s 0-60 mph time of 3.7 seconds is impressive for a vehicle that weighs nearly 6,000 pounds. The 12.2-second quarter-mile time is just slightly faster than the Mercedes-AMG G63, and the Octa is almost two seconds quicker to 130 mph. These numbers are even more impressive when you consider that the Octa has 33-inch tires and a raised ride height.
This Defender is mostly silly in the best way possible. Floor it while cruising at 80 mph and, after the downshift, the acceleration is so strong that the Land Rover squats back and lifts its nose skyward. Let’s see a G63 do that.
Cost and Financial Comparison: The Octa vs. the G63
The starting price of the Land Rover Defender Octa is $153,850, which makes it one of the most expensive SUVs on the market. The Mercedes-AMG G63 starts at $196,900, making it significantly more expensive than the Octa.
2026 Land Rover Defender Octa vs. Mercedes-AMG G63: A Cost Analysis
Engine: BMW Twin-Turbo 4.4-liter V-8 (626 hp) vs. Mercedes-AMG Twin-Turbo 4.0-liter V-8 (577 hp)
Starting Price: $153,850 vs. $196,900
0–60 mph: 3.7 seconds vs. 3.7 seconds
Quarter-Mile: 12.2 seconds vs. 12.2 seconds
Curb Weight: 5,975 lbs vs. 5,990 lbs
In terms of performance, the two vehicles are very evenly matched. The Octa is slightly lighter and has more horsepower than the G63. However, the G63 has more torque and a higher top speed.
When considering a purchase, the Octa offers a significant cost advantage. With a starting price over $40,000 less than the G63, the Octa is a much more affordable option for those who want a high-performance luxury SUV. However, the G63 is also a more exclusive vehicle, and it may be worth the extra cost for those who want to stand out from the crowd.

Transmission: 8-Speed Automatic
This 8-speed automatic transmission is a marvel of engineering, seamlessly delivering power to all four wheels. It is smooth, responsive, and efficient, making it one of the best automatic transmissions on the market today.
Suspension and Chassis: A Ride Like No Other
The Octa’s suspension system is a work of art, combining multilink suspension with hydraulic linkages to combat pitch and roll. This system provides a smooth and comfortable ride, even on rough terrain.

Brakes, F/R: 15.7-inch vented disc/14.4-inch vented disc
Tires: Michelin Primacy All Season 275/50R-22 115W M+S LR
While hydraulics typically make roads silky, the Octa only gets the flatter cornering benefit. The ride isn’t harsh, but it’s jarring, a constant nudge that the springs are supporting nearly three tons. Back-road hustling requires acclimation, because intuition doesn’t indicate that something so tall will corner so flat. The 0.81-g skidpad result isn’t representative of what the Octa feels like when pressed. It will corner faster than you think, once you trust the anti-roll tech to keep it upright. Throw me into that corner, use all the grip, says the Octa. Then you put your foot in it.
Despite the slightly jarring ride, the Octa is a capable off-road vehicle. The 33-inch tires provide excellent traction, and the raised ride height gives it plenty of ground clearance. This vehicle is at home on the road or on the trail.
Exterior Styling and Design: A Modern Classic
The 2026 Land Rover Defender Octa has a modern and aggressive look that is both stylish and practical. The wide fender flares, aggressive front grille, and large wheels all contribute to the vehicle’s menacing presence. The Petra Copper paint with the matte self-healing wrap adds to the vehicle’s exclusivity.
