2018 Jeep Grand Cherokee Trackhawk: Everything is better with 707 horsepower

Jeep says the 2018 Grand Cherokee Trackhawk exists because customers asked for it. Yes, people wanted the 707-horsepower supercharged V8 engine from the Dodge Challenger and Charger Hellcat shoehorned into Jeep's popular SUV, and the world is a better place for it. 

It's better because I can sit on the front straight of New Hampshire's Club Motorsports track, engage launch control and in 3.5 seconds reach 60 mph behind the wheel of a near-5,400-pound vehicle. The exercise is simple, requiring little more than pressing the center console's "Launch" button, smashing the brake with the left foot and mashing of the throttle with the right. The engine rumbles and pops like a dragster, until letting off the brake unleashes a wave of furious torque to shoot the Grand Cherokee hard out of the hole. It is a grin-inducing experience.

If given a longer piece of straight real estate, the Trackhawk can cover the quarter-mile in 11.6 seconds at 116 mph. A really long stretch of pavement will see the five-passenger hauler reach a top speed of 180 mph. The downside is not-so-stellar EPA-estimated fuel economy of 11 mpg in the city and 17 mpg on the highway, but chances are that the people who want this high-horsepower brute don't care one bit.
