While the world was glued to Elon Musk’s victory lap in Washington DC, speculating about the future of electric vehicles under a new regime, I landed in Musk’s birth country, South Africa, to test something different. Meet the Land Rover Defender OCTA, a twin-turbo V8-powered titan that’s the polar opposite of a silent EV. This isn’t just another SUV—it’s a bold, diamond-inspired masterpiece blending rugged grit with jaw-dropping performance. Over a grueling 750+ km trek from Cape Town to Bushman’s Kloof, I threw everything at it: gravel, dunes, dirt trails, you name it. Here’s my deep dive into what makes the Defender OCTA the most powerful and thrilling Defender ever built. Buckle up—this is gonna be a wild ride!

What Is the Land Rover Defender OCTA?

The Land Rover Defender OCTA isn’t your run-of-the-mill Defender. It’s the crown jewel of the lineup, a special edition that JLR (Jaguar Land Rover) says is inspired by the octahedral shape of a diamond—think toughness, beauty, and rarity all rolled into one. But this ain’t just poetic fluff; the OCTA backs it up with serious hardware. We’re talking a 4.4-liter twin-turbo V8 engine pumping out 635 PS (626 hp) and 750 Nm (553 lb-ft) of torque (up to 590 lb-ft in launch mode), mated to an 8-speed automatic transmission. Add in a 6D Dynamics suspension system and off-road upgrades that prep it for the Dakar Rally in 2026, and you’ve got a beast that’s ready to dominate.

On paper, the upgrades might seem simple:

• 28 mm higher ride height
• 68 mm wider stance
• Tweaked bumpers and quad exhausts
• Carbon fiber accents inside

But after two days of relentless driving, I can tell you these changes turn the Defender into something extraordinary—an SUV that rockets from 0-100 km/h in 4 seconds despite tipping the scales at 2.5 tons. This ain’t your average off-roader; it’s a rare breed that fuses luxury, power, and unyielding capability.

First Impressions: A Diamond That Shines Everywhere

Our adventure kicked off in Cape Town, a vibrant city hugged by mountains and sea. The Defender OCTA rolled up looking tough yet refined, its wider arches, beefy grille with matrix LED headlamps, and snarling quad exhausts screaming presence. That 68 mm wider stance and 28 mm lift aren’t just cosmetic—they boost ground clearance and angles, making it a go-anywhere machine.

Leaving Cape Town behind, we veered left at Citrusdal, and the pavement faded into gravel. That’s when the OCTA started flexing its muscles. The drive felt like a rally stage—fast, loose, and alive. It wasn’t just handling the terrain; it was begging me to push harder. This thing’s got character in spades.

The Powertrain: A Twin-Turbo V8 That Roars

Under the hood, the OCTA’s got a 4.4-liter twin-turbo V8—a BMW-sourced mild-hybrid beast delivering a supercar-level punch in an off-road shell. With 635 PS and 750 Nm of torque, it hauls this 2.5-ton rig from 0-100 km/h in a neck-snapping 4 seconds. That’s quicker than plenty of sports cars, and this is an SUV built to bash dunes and crawl rocks.

The quad exhausts belt out a growl that’s pure adrenaline, echoing through the cabin and across the wilds. On our drive, I was blown away by how JLR tuned this powertrain for versatility. The 8-speed auto shifts silky-smooth, with high- and low-range gearing that adapts to anything—blasting down gravel straights or inching through soft sand, it’s always spot-on.

Compared to the old Defender V8’s supercharged 5.0-liter, this twin-turbo setup is smoother but just as ferocious. It’s modern muscle that balances emissions rules with raw, unfiltered thrills—exactly what gearheads live for.

The 6D Suspension: Redefining Off-Road Agility

If the engine is the heart, the 6D Dynamics suspension is the soul. Forget traditional metal anti-roll bars—this system uses hydraulic interconnections between the wheels, with fluid controlling pitch and roll. The payoff? A ride that’s flat and composed on-road, with unreal articulation off-road.

On the gravel roads past Citrusdal, I pushed it hard—rally-style slides, high-speed turns, the works. I felt it slide a bit, got a little nervous, but the OCTA sorted it out like magic. That’s the 6D system doing its thing, adapting on the fly to keep you glued to the ground. The taller ride height and wider stance only make it better, giving this heavyweight a planted feel that’s kinda unreal.

Out at Bushman’s Kloof, tackling off-road trails, it was even more impressive. Loose sand, uneven dirt—it didn’t flinch. The adjustable height (up 28 mm from a standard Defender) let me clear steep climbs and deep ruts without breaking a sweat. This ain’t just fancy tech; it’s a game-changer for off-road nuts like me.

OCTA Mode: Unleashing the Beast

The OCTA’s got a trick up its sleeve: OCTA Mode. Hold down the exclusive OCTA button on the steering wheel, and the pedals glow red, signaling it’s go-time. This mode’s built for loose surfaces, with a controlled launch feature and a custom ABS algorithm that cuts wheel slip while maximizing power.

I tested it on the sand dunes near Bushman’s Kloof, dropping tire pressure to 19-20 psi for better grip. With the Sand Program engaged and ride height cranked up, I let it rip. Patience is key here—you can’t force it, just keep the momentum flowing. The result? Dune-bashing bliss that felt effortless and crazy fun, with the V8’s roar bouncing off the sand.

For on-road kicks, a quick tap of the button flips it to Dynamic Mode, sharpening the throttle and steering. It’s not a Porsche killer, but it’s nimble for a 2.5-ton beast—credit to the faster steering ratio and suspension tweaks.

Interior: Rugged Luxury Meets Real-World Use

Inside, the Defender OCTA mixes tough utility with high-end vibes. The second row’s a standout—I’m 6 feet tall and had plenty of knee and headroom to stretch out. It’s comfy for two, with a chunky armrest, dual climate zones, and two USB-C ports keeping things modern.

Here’s what the cabin brings to the table:

• Supportive seats with chopped carbon fiber accents
• 11.4-inch Pivi Pro infotainment—fast, with Apple CarPlay and Android Auto
• Digital gauges and head-up display for key info
• Meridian audio with “Body and Soul” seat tech for killer sound
• OCTA branding subtly woven in

The cargo area’s massive—perfect for hauling gear on those epic trips you’ve been dreaming about. Whether it’s camping stuff or rally kit, it swallows it all.

Off-Road Prowess: Conquering It All

The Defender OCTA’s off-road chops are legit. Our 750+ km slog hit everything—tarmac, dirt, gravel, rutted trails, and sand dunes. JLR’s plan to run it in the Dakar Rally ain’t just talk; this thing’s built for punishment.

On gravel, the 20-inch all-terrain tires gripped like champs, way better than on tarmac. The traction was so good it gave me the guts to push harder. Out in the dunes, dropping tire pressure and switching to Sand Mode turned it into a sand-slaying machine. There were spots I thought it’d scrape, but the tech and mechanics pulled through like wizards.

Here’s how it stacked up across terrains:

• Gravel: Rally-ready grip and stability
• Sand: Smooth, controlled dune runs
• Dirt: Effortless over ruts and bumps

On-Road Refinement: A Beast That Plays Nice

Off-road’s its playground, but the OCTA’s no slouch on the pavement. It’s a diamond—tough, gorgeous, and a bit rough around the edges. On South Africa’s highways, the wider stance and suspension kept it steady, though the all-terrain tires hum a bit—worth it for their off-road mojo.

The faster steering ratio makes it feel lively, rare for an SUV this big. In Dynamic Mode, it’s fun on twisty roads, though it’s not chasing sports car glory. It’s more about long-haul comfort with a punch of excitement.

One small gripe: the AC struggled in South Africa’s summer heat (32-42°C). It cooled the cabin eventually, but I wanted more chill, faster.

Dakar Dreams: Rally-Ready Roots

JLR’s tossing the OCTA into the Dakar Rally in 2026, and after driving it, I get why. The 6D suspension, beefy V8, and beefed-up geometry scream rally-raid potential. Exact specs—suspension, body, engine—are still hush-hush, but this thing’s got the bones for it.

Across South Africa’s brutal terrain, it wasn’t just comfy—it was adequate, meaning it’s polished yet tough. From gravel sprints to dune thrashing, it tackled stuff that’d shake lesser rigs apart. The Dakar version’s gonna crank that up, and I can’t wait to see it rip.

Who’s It For?

This ain’t your grocery-getter—it’s an enthusiast’s ride. The OCTA’s for folks who live for adventure but want luxury and power too. Think off-road junkies, rally fans, and luxury buyers who need something unique. Priced at £145,300 ($153,475 USD)—or £160,800 ($169,275 USD) for the Edition One—it’s a big spend, but you’re getting a do-it-all monster.

For some markets, like India, the back seat might see more action than the driver’s—plenty of space for chauffeured vibes. But for those who drive it, the OCTA’s a blast that’s tough to beat.
