Test Driver Ratings & Comments

Acceleration commentsA little hesitant getting off the line, then builds good power from 2,000 rpm to its 3,600-3,800 rpm shift point. It launches much harder when you overlap brake and throttle at the line to spool up the turbo. Doing this improved the 0-60-mph time by about 1 second. Still, we're not talking alarming forward progress here. Upshifts are fairly lazy but smooth. Manual shifting is via steering wheel paddles. Does not hold gears to a rev limiter, does not blip the throttle on downshifts.
Braking commentsThe Jeep was consistent in its braking. Consistent in that the distances got progressively longer with each run. Major brake odor by the second run, and by the fourth run (of five) the pedal was significantly longer and softer. On the final two runs (133 feet and 140 feet) it could not brake hard enough to screech the tires the final few feet. The first stop was the shortest at 121 feet. Lots of front-end dive due to the long-travel off-road-capable suspension. Actually rocks back and forth slightly as it comes to a stop. Exhibited some side-to-side squirm with each stop, too.
Handling commentsSlalom: Tall driving position and high center of gravity. Rather slow steering and what feel like hard tires. The body rolls quite a bit on the suspension, but the stability control doesn't let it get too far before it stabs the brakes abruptly. Makes it difficult to get around the cones quickly. Smoothness between the transitions is key or else the ESC system freaks out, massively scrubbing speed. Skid pad: Major body roll. The front tires offer so little grip that it almost feels as if they are on ice, they give way so quickly. Constant throttle corrections are needed (even with ESC fully on) to keep the big Grand Cherokee on the line.
