The latest generation Wrangler is substantially different, but it is really difficult to tell at first glance. Jeep has increased the wheelbase and length for some badly needed extra interior room. A 205-bhp 3.8L V-6 is the standard engine. The model lineup includes the Wrangler X, Sahara, and Rubicon. Rock crawling fans will appreciate the upgraded 4WD system components. New 18-inch alloy wheels are available. Other options include a navigation system, Alpine(R) audio system, and ESP (Electronic Stability Program).
