Availability of a 6-speed manual transmission marks 2005 for Jeep's tradition-bound compact SUV. Wrangler comes in regular-length SE, X, Sport, and Rubicon trim levels. The extended-length Unlimited and Unlimited Rubicon ride a 10-inch-longer wheelbase and are 15 inches longer overall. Unlimited's additional length adds 1.4 inches of rear leg room and more cargo volume behind the rear seat. Wranglers are available with a soft top and plastic side windows or with an extra-cost hardtop with glass windows; Unlimited's soft top features a fold-back forward section for a sunroof effect. The SE comes with a 147-hp 4-cyl engine. All other Wranglers have a 190-hp inline 6-cyl that's optional on SE. A 6-speed manual transmission replaces a 5-speed and is standard on all models. A 4-speed automatic is optional with the 6-cyl. All Wranglers have 4WD that should not be left engaged on dry pavement but includes low-range gearing. Four-wheel disc brakes are standard or optional on all but the SE and X. ABS is available only on the Sport. Front side and curtain side airbags aren't offered. A 30-inch tire package is standard on Unlimited, optional on Sport. Rubicon and Unlimited Rubicon are intended for severe off-road use and come with 31-inch-equivalent off-road tires, front and rear locking differentials, and low-ratio gearing. Towing capacity is 3500 lb on Unlimiteds; 2000 on X, Sport, and Rubicon; 1000 on SE.
