With sales hitting a five year high, Jeep is aiming to keep their momentum going with the updated Jeep Grand Cherokee. For this year's New York Auto Show, Jeep unveiled two new variants of its best-selling SUV, the off-road oriented Trailhawk and the revised Summit.

For 2017, the Grand Cherokee gets an updated front fascia, revised tail lights, a more plush interior and updated technologies.

2017 Jeep Grand Cherokee Trailhawk

The Trailhawk is a new addition to the Grand Cherokee lineup. Being an off-road package, it gets raised suspension and rides on 18 inch rims wrapped in all-terrain tires. Jeep has also installed a detachable front bumper for a wider approach angle when off-roading.

This off-road spec Grand Cherokee also gets special damping for its air suspension and its setting are unique to the Trailhawk. According to Jeep, the specially tuned dampers offer better articulation for climbing over rocks and keeps the wheels in contact with the ground as much as possible. Increasing the Trailhawk's off-road capability even further is a rear electronic limited slip differential. Heavy duty tow hooks and a blacked out hood further differentiates the Trailhawk from the rest of the range.
