The Jeep Wrangler (JK) is the third generation of the Jeep Wrangler off-road vehicle. The Wrangler was unveiled at the 2006 North American International Auto Show in Detroit, the JK series 2007 Wrangler Unlimited at the 2006 New York Auto Show.
The car's body and chassis were completely redesigned during the era when Jeep was part of DaimlerChrysler. Just like the Willys MB, the CJ Jeeps and the Wranglers before it, the JK continues to have a separate body and frame, rigid live axles both front and rear, a fold-flat windshield, and can be driven without doors. Also, with the exception of optional 4x2 models, the Wrangler JK continues to have part-time four-wheel drive systems, with the choice of high and low gearing.
In addition to the traditional 2-door Jeep, the JK introduced for the first time a factory standard four-door model, called the Wrangler Unlimited. Contrary to the first, TJ-based Unlimited, and the CJ-8 "Scrambler", its wheelbase is stretched by 20 instead of 10 inches. The Wrangler Unlimited became a big sales success — by mid-2017 three quarters of all new Wranglers listed for sale were four-door models.
