2025 Land Rover Defender Octa Brings a Mighty 626-Horsepower V8 to the Party

It will be rare, and if you want one, it'll cost you

Power, off-road capability and luxury? Where have we seen that before?

Since Land Rover reimagined its formerly utilitarian Defender in 2020, it’s been defining the model as its own range of SUVs, beyond just being a rung on the ladder to, say, the supercharged Range Rover SV Autobiography. Case in point is the 2025 Land Rover Defender Octa, which plays the same sort of power games as the high-strung Range Rovers we’re used to, but in a more “I’ll go anywhere I damn well please” sort of package. If anything, this feels like a more direct answer to the Mercedes-Benz G-Class in terms of both its powertrain offering and incontrovertible off-road prowess. Oh, and it’s expensive too.

Based on the four-door, shorter-wheelbase Defender 110, the Octa makes its gargantuan performance by way of a V8 engine. It’s not the old supercharged 5.0-liter mill we’re used to, though: JLR has consigned that engine to the pages of history. Instead, the new Land Rover Defender Octa uses a BMW-sourced, 4.4-liter twin-turbocharged V8. Just like the decidedly road-focused Range Rover Sport SV, you get a hearty 626 horsepower and 553 lb-ft of torque making its way to all four wheels through an 8-speed automatic transmission. To bring everything to a expedient halt, this high-performance version gets larger 15.7-inch front brake discs with 6-piston Brembo calipers. It also has, according to JLR, “the fastest steering ratio of any Defender vehicle to date.”

For reference, the most potent Defender 110 V8 model beforehand put out just 518 horsepower, so this is a major step up. In fact, Land Rover claims the Octa can make the 0-60 sprint in 3.8 seconds, at least when it’s on 22-inch wheels and road tires. Not that it should be, mind you, but you know how it is…when’s the last time you actually saw a new G-Wagen off-road?

The 2025 Land Rover Defender Octa isn’t exactly a Baja rig, especially when you take into account its six-figure price tag. However, it does get longer and tougher wishbones and new adaptive dampers, as well as the company’s “6D” suspension, also from the Range Rover Sport SV. Ground clearance increases by 1.1 inches over the standard Defender 110 (to a maximum of 12.6 inches), while Land Rover also widened the Octa by 2.7 inches, adding marker lights and fender flares to accommodate the now-81.3-inch width. The Octa’s wading depth is 3.9 inches higher at 39.4 inches maximum, while reshaped front and rear bumpers increase the approach and departure angles to 40 degrees and 42 degrees, respectively. Breakover is better as well, at 29 degrees.

Even though you’ll get the quickest results on road tires, if that matters to you, the Octa comes on 33-inch Goodyear Wrangler all-terrain tires in its most dirt-worthy configuration from the factory. It’s not just any Goodyear Wrangler, though, as JLR says the tread pattern is specific to the Octa, while the company also had to come up to a solution to get solid all-terrain tires while accommodating the large brakes and without compromising the car’s on-road handling capability. While other tire and wheel packages increase the top speed up to as high as an electronically limited 155 mph, the off-road package caps the speed at 99 mph.

How much will the 2025 Land Rover Defender Octa cost?

As you’d expect, the 2025 Land Rover Defender Octa comes with a launch variant, called Edition One. This model (shown above) comes in Faroe Green with special 20-inch wheels wrapped with those Goodyear Wrangler tires. The exterior sees carbon trim pieces, while the cabin gets new performance front seats, clad in Khaki and Ebony Ultrafabric upholstery.

A standard version of the Octa will be available beyond the Edition One, and that widens the available color palette to Carpathian Grey, Charente Grey and Petra Copper The interior also comes with Burnt Sienna leather by default, though you can get the textile option like the Edition One.

The Land Rover Defender Octa — meant to refer to a cut diamond’s octahedron shape — will start off with just a 300-unit run. The base version starts off at $153,475, while the more exclusive Edition One that will initially roll out to those select few buyers will clock up a price tag of $169,275.

Orders are open right now, and the Octa will officially launch at the Goodwood Festival of Speed next month.
