Test Driver Ratings & Comments
Acceleration commentsStill a slug off the line, but the new V6 comes on strong from 3,700 rpm to its 6,400-rpm redline/shift point. It's 1.8 seconds quicker to 60 than previous V6/four-speed auto combo. New five-speed automatic upshifts very slowly but smoothly. Power braking is of no help, could go considerably quicker with standard six-speed manual. Manual-shifting ability of auto is via console lever (slap left to downshift). Will hold gears to 6,400-rpm rev limiter. Does not blip throttle on downshifts.
Braking commentsLong travel, slightly mushy pedal. Lots of nose dive and enough side-to-side squirm that countersteering was required. All things which are really not that surprising in a Wrangler. But stops were consistent and fade-free.
Handling commentsSkid pad: Overly intrusive ESC (whether on or off -- it's never fully off unless you're in 4WD) means you have to dance, yes I said dance a Wrangler, at the edge of ESC intervention. System loves to add brakes. Not much grip, lots of body roll. Slalom: Could not go as fast as last Wrangler because of an insanely aggressive ESC system. It's so intrusive, whether on or off, that it's actually dangerous because of how quickly and with how much force it stabs the brakes. I almost took out several cones because it wouldn't let me finish my turn, instead forcing me to drive straight while it jammed on the brakes. The Wrangler definitely has more to give, as it wasn't at a real sliding point. Suspension and tires would allow a far quicker time. Seats suck in terms of lateral support, letting you flop about big time.
