Does the world need a Jeep capable of 180 miles per hour? Of course not. That’s about as far afield as it gets from the spindly World War II-vintage four-wheel-drive machine that trudged through the mud and replaced the horse in the U.S. Army cavalry some 75 years ago.
But today, SUVs are mainstream family transportation and standing apart from the crowd requires some heroic measures. Enter the 2018 Jeep Grand Cherokee Trackhawk, a 707-horsepower sport-utility for those occasions when 706 hp just wouldn't be enough. At an MSRP of $85,900, the Trackhawk is both the most powerful and most expensive SUV in Jeep’s lineup.
