Test Driver Ratings & Comments
Acceleration commentsWeak. Long, tall gearing is painfully obvious when accelerating quickly. Fortunately, the engine is willing to rev, but should it have to in this midsize SUV application?
Braking commentsRelatively long-travel, soft pedal, but consistent distances and stable performance. It stays straight, too, with no wandering.
Handling commentsSkid pad: Highly managed. Even with stability "off" (it's not fully off) in Sport mode, this is a stomp-and-steer procedure. Just hold your foot at a constant throttle opening and steer. "Driving" doesn't actually help much. Slalom: Feels stable, safe and highly managed here as well. Sport mode does expand the handling limits over Auto mode, but expect this Jeep to simply go where it's pointed within the threshold of physics.
