November 04, 2011

The big news for the 2012 Jeep Wrangler wasn't so much the spruced up interior, but rather the new, standard, 3.6-liter Pentastar V6. This engine makes 285 horsepower and 260 pound-feet of torque. Those are big numbers for a Jeep that starts at just over $20 grand.

Not only does our Long Term Wrangler have the new motor, but it's also got a six-speed manual. We've already tested the 2012 Wrangler Sahara Unlimited with the five-speed manual and were as curious as you are as to how the smaller, lighter Wrangler with row-your-own box did when pushed to its limits at the track.

You asked for it so here we go...

Acceleration: Long-travel, high-point engaging clutch is great for off-roading but horrible for a drag strip. With TC off, in 2WD it'll light the rear tires. A little spin works, but too much is too much. Upshifting to a different zip codes with the long-neck shifter takes time, but it'll still chirp 1-2 and 2-3 if done quickly enough. Tall gears let the engine pull (for a long time in each gear) all the way to redline where power fades slightly.

Braking: Lots of dive, lots of wiggle and some directional change even requires steering to keep straight. Tires howl every time. Moderate fade.

Handling

Skid pad: Silly, really, considering how low the threshold is for non-defeat ESC. So low that the Jeep barely leans at this slow speed. Steering barely loads up. Barely a measurable difference with TC off.

Slalom: Also silly with early onset ESC intrusion -- best run was with minimal steering input and staying below the ESC's radar. Also essentially no reason/difference with TC off.
