The Jeep Wrangler received its first major overhaul since 1998, and kicked off 2007 with all new features like shorter grille slats, clearly separated fenders, and fog lights incorporated into the front bumper. The brand also added a curved windshield and better roof integration to the new vehicle, which it said helped reduce interior noise by 20 percent. Calling itself the Wrangler JK, this redesign was also the debut of a 4-door model called the Unlimited, which was over 20-inches longer than the 2-door, and would go on to become extremely popular.
