FCA's Jeep unit will roll out two more Grand Cherokee models, including the Trailhawk and Summit, for 2017. The two models appeared at the New York International Auto Show, and will arrive at dealer lots in late summer.

The 2017 Jeep Grand Cherokee Trailhawk adds off-road 4x4 capability features, including Jeep's Quadra-Drive II 4x4 system with rear Electronic Limited Slip Differential (ELSD) for all powertrains, a unique version of Grand Cherokee's Quadra-Lift air suspension developed for Trailhawk that offers improved articulation and total suspension travel, as well as Selec-Speed Control with Hill Ascent Control. Skid plates and a Trailhawk-specific anti-glare hood decal are also standard.

Approach angles on the Jeep Grand Cherokee are 29.8 degrees or 36.1 degrees when the lower front fascia is removed for severe off-roading, while the breakover angle is 27.1 degrees and the departure angle is 22.8 degrees. Grand Cherokee Trailhawk models offer up to 10.8 inches of ground clearance.

The 2017 Jeep Grand Cherokee Summit arrives with an updated front fascia, grille and LED fog lamps, with new 20-inch polished aluminum wheels. The full leather interior boasts a Nappa leather-wrapped dashboard, center console and door panels, and Laguna leather seats with edge welting.

2017 Grand Cherokee Summit adds more standard equipment such as auto-folding power mirrors, headlamp washers, blind spot detection, forward collision warning, adaptive cruise control and, for the first time, lane departure warning and parallel and perpendicular park assist.
