Mixing off-road ability with pavement-chewing power, the 2018 Jeep Grand Cherokee Trackhawk is one of the quickest SUVs in the world. It's powered by the same 6.2L, 707 hp supercharged V8 as its Hellcat cousins, but thanks to the all-wheel-drive system, it's a little faster. That means 0-60 in 3.5 seconds and a top speed of 180 mph, helped along by an eight-speed automatic gearbox. Styling changes are primarily functional, with an additional slit in the front fascia and an intake in place of the driver's side foglight to help route more air to the engine. Brembo brakes ensure you can get slowed down in a hurry, and the driver-focused cockpit and Bilstein shocks provide a comfortable ride at speed.
