Test Driver Ratings & Comments

Acceleration commentsWow does this feel like an antique. Four-speed? Seriously? Each gear takes an eternity that's got a raspy soundtrack. Upshifts are rather harsh, then revs drop way out of power band. I'll say this, however; it's very consistent (and slow). Allows pedal overlap, but it didn't help.
Braking ratingPoor
Braking commentsAside from the fact there's very little rubber on the pavement (with such large lugs) the ABS manages to keep the Jeep straight and reasonably fade-free. Lots of dive, but that's expected.
Handling ratingVery Poor
Handling commentsSkid pad: An utterly pointless waste of fuel and tires. The stability control barely allows this Jeep to go around in a circle. Slalom: Similarly futile due to ultra-conservative ESC. It's a fish out of water -- like taking a Porsche 911 GT2 up the Rubicon Trail.
