Jeep Grand Cherokee Trackhawk Revealed

It has the same supercharged 6.2-liter V8 engine used in the Dodge Challenger Hellcat muscle auto, which is "the most powerful muscle vehicle ever", according to Fiat Chrysler Automobiles, parent company of both Dodge and Jeep.

That's good enough, says the maker, to take this 2433kg beetle-crusher from a standstill to 100km/h in 3.5 seconds, kill a quarter-mile in 11.6 seconds at 185km/h and top out at 288 km/h.

The new Grand Cherokee Trackhawk will go on-sale in the United States later this year but there are now no plans for it to arrive Down Under.

The Trackhawk ousts the 449kW Bentley Bentayga for the title of the world's most powerful off-roader and eclipses Porsche's upcoming 500kW Cayenne Turbo S E-Hybrid before it even arrives. The Trackhawk will be presented at this week's NY auto show, but details and photos can be found here.

"The new Grand Cherokee Trackhawk delivers astounding performance numbers. with luxury, refinement and an array of innovative advanced technology", said Mike Manley, head of Jeep Brand - FCA Global.

Torque is delivered to the rear wheels via new ultra-high-strength steel half-shafts. The tow models the Trackhawk to haul 7,200 pounds with a 60/40 torque split.

Anyone with dreams of track-day heroics will be pleased to know Jeep has tweaked the standard Grand Cherokee SRT suspension to handle the extra power on tap. The front brakes are 15.75-inch, two-piece vented rotors with six-piston calipers. The tech has various modes: 40-60 in Auto, 50-50 in Snow, 60-40 in Tow, 35-65 in Sport, and 30-70 in Track. The housing is redesigned relative to the one in the SRT8 with revised ring-and-pinion tooth geometry and a new four-point axle mounting scheme to better distribute the enormous forces attempting to twist it away from the chassis. The SUV sits lower on Bilstein adaptive dampers, lightweight 20-inch alloy wheels, wrapped in special 295/45ZR20 section Pirelli rubber. There's also the obligatory launch-control system, backed up by the largest brakes ever fitted to a Jeep, while driver support systems include lane-departure warning, active cruise control and blind-spot monitoring. It also features a launch control system that optimises performance by coordinating the engine, transmission, driveline and suspension for consistent take-offs and straight-line acceleration.

While its horsepower stats are an anomaly in the SUV segment, the Trackhawk is not alone in offering surprising performance. The rear is accented with four-inch black-chrome quad exhaust tips. Each front door gets a "Supercharged" badge, and the hatch gets a "Trackhawk" badge.

Fiat Chrysler's 8.4-inch Uconnect infotainment screen doesn't only allow for Apple CarPlay and Android Auto compatibility, it also hosts Trackhawk-exclusive Performance Pages.
