2018 Jeep Grand Cherokee Trackhawk
**NOW TAKING ORDERS**
The Grand Cherokee Trackhawk is a Hellcat by another name. Under the hood is the same 707-horsepower supercharged V8 from the sinister corporate cousins Charger and Challenger and Jeep claims the Trackhawk is capable of just 3.5-second 0-60 mph run and a quarter-mile time of 11.6 seconds. The former is right in line with the Challenger Hellcat.
The Grand Cherokee Trackhawk also offers a unique difference to the Hellcats, and its not the SUV body style. The Trackhawk is all-wheel-drive. Power goes from the supercharged V8 to an 8-speed automatic and a single-speed transfer case. There’s also an electronic limited slip differential at the back. Jeep beefed up the transfer case with a wider chain that features forged sprockets. The rear drive shaft and half shafts have been strengthened to handle the extra power. Power is split 40/60 front and rear in the default automatic setting, and becomes more rear biased in more aggressive driving modes. In the sportiest “Track” mode, power is split 30/70. In the least aggressive “Snow” mode, power is split 50/50. The sportier drive modes also firm up suspension and decreases shift times.
Helping manage all the power is a high-performance suspension with adaptive Bilstein shocks. The suspension lowers the SUV a full inch compared with normal Grand Cherokees. Wheels are 20 inches in diameter and 10 inches wide wrapped in 295-millimeter wide tires, either all-seasons or optional three-seasons. An optional forged set of wheels is available, too, which Jeep says will save 12 pounds of weight. The wheels are stopped by Brembo six-piston calipers and 15.75-inch rotors up front, and four-piston calipers and 13.73-inch rotors out back. Jeep says the front brakes are the largest ever fitted to one of its vehicles.
Visually, you’ll be hard-pressed to tell a Grand Cherokee Trackhawk from the current SRT variant. The bumpers and fender flares are roughly the same. But a tell-tale sign is the lack of fog lights. This is necessary for additional air flow, and on the driver’s side, the space a fog light would’ve taken now supplies cold air to the engine. The Trackhawk also gets “supercharged” and “Trackhawk” badges throughout. The interior also gets some subtle updates. Black chrome and carbon fiber trim adorn the inside, and heated and cooled Nappa leather and suede front seats are standard. However, these can be upgraded with an optional real metal trim package and a leather package available in black or the “Dark Ruby Red” shown above. A panoramic sunroof, matching red seatbelts, and an 825-watt sound system are available. All Trackhawks come with “Performance Pages” with timers, gauges, and driving settings.
