A 707-horsepower Jeep answers a question no one asked about SUV performance, and time will tell if it meets a demand no one knew was there. Fiat Chrysler Automobiles is about to start building a batch of 2018 Jeep Grand Cherokee Trackhawks with a supercharged 6.2-liter V-8 engine. There are already orders and handraisers for the limited-run SUV rocket that goes on sale in the fourth quarter.
The Hellcat engine generates 707 hp and 645 lb-ft of torque, distributed through the upgraded TorqueFlite eight-speed automatic transmission. It is billed as the fastest SUV in the world. Jeep claims it will do 0-60 mph in 3.5 seconds. I did it in 3.4 seconds on my first try.
But it comes at a steep price.
The Trackhawk starts at $86,995, but you can easily option it up to a $100,000 vehicle. The one I drove in Portland stickered at $99,965, about $20,000 more than an SRT. The options included a $5,000 leather-wrapped interior package, upgraded audio and entertainment system, dual-pane panoramic sunroof, and a trailer-tow package. Other upgrades go from the standard 20-by-10-inch Titanium finish wheels with Pirelli Scorpion Verdes all-season tires to the lighter forged aluminum wheels with three-season Pirelli P-Zero tires.
