It's the fastest SUV in the world.

After building home market anticipation for the 2018 Jeep Grand Cherokee Trackhawk for over a year, the Hellcat-powered Jeep SUV is finally officially here. And what an engine it is. The 6.2-litre supercharged Hellcat V8 in the Trackhawk produces 707 horsepower and 645 pound-feet of torque. Yes, 707 hp. Take that. Range Rover Sport SVR, and your puny 550 hp. 

For reference, the version in the U.S.-market Challenger and Charger SRT Hellcat models make 707 hp and 650 lb-ft. There were rumours that engineers might de-tune the engine in the Jeep for the longevity of its all-wheel-drive components, but apparently only small adjustments were necessary.

The powerful engine can accelerate the 2,433-kilogram Jeep to 60 miles per hour in just 3.5 seconds, which Jeep claims makes the Trackhawk the quickest SUV ever. However depending on your definitions of an 'SUV', the Tesla Model X P100D with the Ludicrous Mode Easter Egg can allegedly make that sprint in 2.8 seconds. Jeep further reports that the hotrod Grand Cherokee can run the quarter mile in 11.6 seconds and achieve a top speed of 180 mph. Plus, it can tow up to 3,266 kilograms.

The Trackhawk is only available with an eight-speed automatic gearbox, which features upgrades for added strength over the version in the Hellcat-power Challenger and Charger. It routes power through an all-wheel-drive system with an electronically controlled limited slip differential for the rear wheels. Depending on the drive mode, the tech is able to vary the front-rear torque split, including 40-60 in Auto, 50-50 in Snow, 60-40 in Tow, 35-65 in Sport, and 30-70 in Track.

A set of 400 millimetere Brembo brakes in front and 350 mm rotors in the rear let the Trackhawk slow just as well as the SUV accelerates. The company claims that braking to a stop from 60 mph requires just 114 feet.

Aesthetically, the Trackhawk gains some functional upgrades that make the most of its improved mechanical parts. The extra slit in the front fascia aids cooling, and an intake in place of the driver’s side foglight routes cool air to the engine. Body-colour flares cover the 20-inch wheels. There’s also a new quad-tip exhaust with a dark finish on the tailpipes.

Inside, there’s a driver-focused cockpit. The tachometer now sits in the centre of the instrument panel, and the 8.4-inch infotainment system features Trackhawk-exclusive pages for monitoring performance metrics. Nappa leather seats with suede seats are standard. An available Signature Leather Interior Package covers the whole cabin in black or Dark Ruby Red. This dark crimson is also an option for the seat belts.
