Last year Jeep CEO Mike Manley confirmed the automaker would stuff the 707 horsepower 6.2-liter Hellcat V8 under the hood of the Grand Cherokee SRT and he’s now made good on his word. Here it is, in all its supercharged, all-wheel drive glory: the 707 horsepower Jeep Grand Cherokee Trackhawk.
Let’s get right down to the important stuff. The Trackhawk packs the 6.2-liter Hellcat V8 under its hood, which is linked up to a beefed up version of Fiat Chrysler’s eight-speed automatic transmission. It’s present in full 707 horsepower form, but is down 5 lb-ft of torque over the Challenger and Charger Hellcat at 645 lb-ft – a loss chalked up the differently routed exhaust system. The Grand Cherokee SRT’s all-wheel drive system remains, but is made a bit more robust with a stronger rear axle and half shaft and a sturdier differential.
The numbers are as follows: 0-60 mph in 3.5 seconds, a 1/4-mile time of 11.6 seconds at 116 mph and a top speed of 180 mph. According to Jeep CEO Mike Manley, the Trackhawk is the “most powerful and quickest SUV,” in the world.
There’s other performance features apart from just a big engine. Just like the 2018 Dodge Demon, the SUV will get a special Torque Reserve function that holds the bypass valave in the supercharger open, limiting torque and allowing the driver to easily build boost from a standstill. Large Brembo brakes measuring 15.75-inches out front and 13.73 inches in the rear are also present, helping bring things from 60 mph to 0 in just 14 feet.
Five driving modes help use all 707 horsepower appropriately: Automatic, Sport, Track, Tow and Snow. Track mode splits torque by 30/70 front to back (it’s 40/60 Automatic mode) and also tells the transmission to speed up the shifts. Tow mode helps access all 7,200 lbs of tow capacity. The SUV sits 1-inch lower than a standard Grand Cherokee and also features revised front suspension to help deal with the extra loads at hand.
The Trackhawk appears visually similar to the Grand Cherokee SRT but is set apart by unique 20-inch wheels (available with either Pirelli 295/45Z Scorpion Verde All-Season tires or Pirelli P Zeros), Trackhawk badges, a quad-exit exhaust system and air intakes where the fog lamps normally are. The interior is mostly the same with an SRT steering wheel, bolstered leather seats and an 8.4-inch UConnect infotainment system with Apple CarPlay and Android Auto. All the usual safety features, such as adaptive cruise control, front brake assist, blind-spot monitoring, forward collision warning and more, are also standard.
Pricing for the 2018 Jeep Grand Cherokee Trackhawk has yet to be announced, but $80,000 – $85,000 USD seems to be the most common estimate. We’re expecting initial deliveries to commence sometime later this year in either the late summer or early fall.
