2003 4x4 of the Year

Choosing a Winner in Our Biggest Test Ever!

Jeep Wrangler Rubicon

The other half of the people reading this expected the Wrangler to win it all this year. If there were fewer luxury SUVs in the test, or we didn't drive on paved roads, there's no doubt the Wrangler would have done much better than the scoring shows. But since our test evaluates all aspects of a 4x4 the Wrangler sank in the ranking. It's no surprise that when it came to crawling around off-road no other 4x4 came close to the Jeep. Have you ever tried to follow a TJ in a Super Duty? It's no contest. The Rubicon had the rockcrawling portion of the test in the bag. There weren't many times that our judges even needed to use both lockers thanks to all the suspension travel and low gearing of the five-speed and NVG 241J transfer case. But it sure was nice to have them! Our judges learned to appreciate that even when the rear differential is unlocked it is still a very good limited slip. Since we hardly ever lifted a rear tire we always had plenty of traction.

For some unknown reason the '03 Rubicon is sprung much firmer than any other Wrangler we've driven. Combined with the short wheelbase it gave us great maneuverability on the technical trails, but it became a pain in the butt (literally) on the fast gravel roads. Fortunately we loved the new seats and they isolated the judges from some of the jarring ride. Judges also gave high marks to the 4.0L engine's low-end torque, but there wasn't always enough top end to keep up with the rest of the convoy on the highway. Without question the Goodyear MT/R tires were the best off-road tires in the test, but they also contributed to the Wrangler's poor braking distances and overall road noise. Speaking of noise, it was hard to go from driving the Lexus GX 470 and listening to the radio to hopping into the Wrangler and listening to the tires wearing without deducting some points. Add in a soft top that only made the Jeep louder and you'll understand why this is the last vehicle that the judges would have wanted to take cross-country.
