2012 Jeep Wrangler

The constant struggle for Jeep is civilizing the Wrangler without killing its off-road prowess. After all, no matter how capable it may be on the Rubicon Trail, a scant few customers are willing to endure a choppy on-road ride or an interior racket that sounds like a snare drum in an oilcan. In the past 18 months, the Wrangler has nearly been upended. The designers ditched the granite-hard interior for one with softer materials and gentler curves. They redesigned and thickened the soft top to reduce wind noise. A more powerful and efficient driveline replaced the ancient 3.8-liter V6 and four-speed automatic. The new Wrangler, which is available with two or four doors, is the most livable ever. And it still has the steep approach and departure angles, stout running gear and hardware—skidplates and locking differentials—that make it the most capable off-roader available. Many vehicles can take you to remote locations, but you're most likely to make it back home in a Wrangler.

The Wrangler's All-Terrain Anatomy 

1. ENGINE 

The new 3.6-liter V6 produces 285 hp, 83 more than last year's, yet is 21 percent more fuel-efficient. An aluminum block saves 90 pounds over the old iron 3.8-liter. 

2. TRANSMISSION 

The five-speed automatic has a wider ratio spread for better fuel economy. The six-speed manual is still available. 

3. FRONT AXLE 

No independent suspension here. The rigid axle is tough and can be optioned with an antiroll bar that electronically disengages so the axle can freely rock and follow rough terrain. 

4. TRANSFER CASE 

Once engaged, the transfer case sends power to the front wheels. Rubicon models offer a ridiculously low 4.10:1 low-range ratio so they can inch along slower than a walking pace and gingerly crawl over obstacles. 

5. REAR AXLE 

Drivers can outfit the Wrangler with one of three final-drive ratios to enhance either fuel economy or low-speed crawling ability.
