The "need for speed" is the driving force behind Jeep's new SUV.
The 2018 Jeep Grand Cherokee Trackhawk is everything that we had hoped, with the supercharged 6.2L Hemi delivering 707 horsepower and 645lb-ft of torque, making this Hellcat-powered beast the world's most powerful gasoline-powered production SUV - beating every other SUV in the world by a massive margin.
The Jeep Grand Cherokee has just received a major horsepower upgrade.
Under the bonnet of the Trackhawk sits the same force-fed 6.2-litre V8 that produces 527kW of power and a monstrous 874Nm of torque, enough to propel it from 0-100kmh in 3.6 seconds, cover the quarter mile in 11.9 seconds and reach a top speed of 290kmh.
Look for the Grand Cherokee Trackhawk to begin arriving in Jeep showrooms in the fourth quarter of the year. The eight-speed Torqueflite transmission shares the gear ratios of the Hellcat cars but is beefed up slightly for AWD towing duty, earning the name 8HP95, up from 8HP90. Meanwhile, Track reduces the shift times between each gear and torque split is at 30:70. Braking responsibilities are taken care of by the biggest set of Brembos ever fitted on a Jeep - 400mm discs at front and 350mm at rear with six and four-piston callipers respectively, thus bringing the SUV to a screeching halt from 100kmph to zero in mere 114feet. Earlier rumours suggested that the Jeep engineers might have to de-tune the motor to sustain the longevity of the SUV's all-wheel-drive components. Large diameter brake rotors are used with yellow paint for the Brembo calipers.
The rear axle will be strengthened significantly with a stronger rear drive shaft connecting to it. Taking care of safety is a set of 15.75-inch (400 millimeter) Brembo brakes in front and 13.78-inch (350 mm) rotors in the rear, with the company looking towards a 60 miles per hour (97 kph) stop in 114 feet.
The Jeep Grand Cherokee Trackhawk is a vehicle aimed at people who want two things: a practical, high-riding SUV and to be faster than 99% of the world's auto owners. There are also quad exhaust pipes. The standard wheels are 20-inch items, but there's a forged aluminium option that saves 5.4 kg.
The Trackhawk, which will come with a 3272kg tow capacity in the USA, comes with a host of chassis additions over the Grand Cherokee SRT too. Each front door gets a "Supercharged" badge, and the hatch gets a "Trackhawk" badge. The driver-centric interior will come with premium materials, a black chrome finish and an 8.4-inch infotainment system.
But the most fascinating thing could be the 8.4-inch Uconnect touchscreen with Trackhawk-exclusive Performance Pages.
