When outright power meets off-road ability.
Supercars are quickly surpassing the 700 horsepower mark, as are a whole host of super-SUVs. Take the Lamborghini Urus, for example, which finds rivals in a whole host of 650hp+ soft-roaders courtesy of manufacturers and various aftermarket tuning houses. But are there any serious off-roaders that can push the 700hp+ limits of our imaginations? As it so turns out, there have been a few available, and we’ve found the most intimidating of them all.
The regular Mercedes-AMG G63 6x6 is no child’s plaything. It’s a military-purpose engineered behemoth with 6-wheel-drive, numerous locking differentials, low range transfer case, and a twin-turbo 5.5-liter V8 cranking out 536 hp. But when Brabus – famous for developing monstrous Mercs - gets its hands on the G63 6x6, the wick is turned way, way up, rigging new turbos with a new engine tune to work 700 hp from the 5.5-liter displacement. It’s enough to take the 4-ton monster from 0-60 mph in 7.4 seconds, while having no negative effects on its off-road ability.
To celebrate the 50th anniversary of the Easter Jeep Safari in 2016, Jeep dug deep into the Mopar parts shed and equipped a short-wheelbase Wrangler with the 707-hp supercharged V8 from the Dodge Hellcat family. The Wrangler Trailcat one-off also featured an extensively reworked body, a 6-speed manual gearbox, 39.5-inch BF Goodrich Krawler tires, and bucket seats from a Dodge Viper inside. It’s the kind of insanity we love, and makes for one badass Wrangler we wish would reach production.
To celebrate 25 years of Hennessey Performance, the American tuner produced 25 versions of the VelociRaptor 25th Anniversary 700 Supercharged. What starts life as a Ford F-150 Raptor gets a 2.9-liter supercharger system, high flow induction kit, upgraded injectors, and a new engine map to deliver 704 hp to all four off-road tire-equipped 20-inch wheels. The bumpers get tweaked, vinyl stickers get added, and the suspension gets beefed up to turn the 25th Anniversary VelociRaptor into a true off-road monster with the go to match the show.
If that Brabus G63 6x6 is a stretch beyond your budget, then perhaps a regular 4-wheeled Brabus might be more what the doctor ordered. The Brabus G850 takes a standard previous generation G63, increases displacement from 5.5- to 6.0-liters on the twin-turbo V8, replaces the standard turbos with Brabus units, and adds forged pistons, Brabus intake manifold, and a Brabus engine control unit to turn the Gelandewagen into an 850 horsepower destroyer of off-road worlds. On-road performance is mega too, with 0-62 mph taking 4.0 seconds flat and top speed being boosted to 162 mph. All the off-road bits remain as robust as ever, meaning the G850 can still go just about anywhere.
Bless Hennessey, it makes the search for high horsepower so easy these days, and if the Chevy Silverado is your cup of tea, the Texan tuner will give it a dash of steroids to ensure it’s the beefiest thing this side of a G63 6x6. The 6.2-liter V8 engine gets a big supercharger, air to water intercooler, forged pistons, new engine management, high flow air intake, and more, to boost power to an astonishing 805 horsepower, with torque kicked up to 812 lb-ft.
3.9 seconds is all it takes to get from 0-60 mph, and the quarter mile is dealt with in 12.3 seconds. What’s more is that none of the rugged appeal and capability is lost in the process, meaning the Silverado is ready for towing and off-road duty in a heartbeat.
If you want a six-wheeled pickup you’ve got to buy a Benz, right? Wrong. Hennessey figured there’s an all-American way to answer the 6-wheeled pickup dilemma. It will redo all the bodywork on a Silverado Trail Boss Truck, add an extra axle and drivetrain components, and supercharge the 6.2-liter V8 with the HPE700 package to create the 705-hp 6-wheeled, all-wheel drive Hennessey Goliath 6x6.
To top it off, it gets an eight-inch lift kit, all-new rear suspension, 20-inch wheels, 37-inch BF Goodrich tires, and a rollbar upgrade that result in the Goliath 6x6 being exceptionally competent off-road, ready to go toe to toe with Brabus’s tuned G63 6x6. A further 808 hp stroker engine upgrade is also available because sometimes, too much power isn’t enough.
Back in 2015, Shelby figured it would rework the already impressive Ford F-150 SVT Raptor. The result was dubbed the Shelby Baja 700 and featured a 6.2-liter supercharged V8 engine developing, you guessed it, 700 horsepower. The suspension was beefed up with Rouge Racing control arms, bypass rear shocks, and 18-inch wheels shod in BF Goodrich K02 all-terrain tires. Shelby striping was of course standard, and the interior got a Katzkin leather treatment, a three gauge dash pod, and individually numbered dash plaque. Just 50 of these mega-Raptors were produced by Shelby, making them almost as rare as they are incredible.
From the company that brought you the Rezvani Tank offroader and Beast supercar comes the Rezvani Tank X. It’s a luxury off-road demon with FOX off-road suspension, 16-inch, 8-piston brakes, suicide doors, leather seats, on-demand 4x4, LED lighting, night-vision with thermal imaging, and a 707-horsepower supercharged Hellcat V8 engine. There’s even a military version of the Tank off-roader replete with bulletproof armor and ‘numerous defensive features.'
At $259,000 the Rezvani Tank X might be one of the most expensive off-roaders here, but it’s fully street legal and there’s no other 700-hp offroader that’ll make you feel more like you can survive the apocalypse than this one.
