Jeep is expected to release a redesigned Jeep Wranger in 2007. The new Wrangler, codename TK, will debut as a 2-door, but a longer wheelbase four door and a truck variant are planned. Other potential changes include a fixed roof with removable panels instead of a soft top and a separate hard top. Removable doors and a fold-down front windshield should still be available. The powertrain options will change as well. The base engine will be a 2.4-liter four with an optional 3.7-liter SOHC V-6 from the Liberty. A 4.7-liter V8 may be an option later. Gone is the straight-6 that has been an icon in the Wrangler. While that engine was fine for off-road ventures, honestly it felt winded at interstate speed. It also appears that the tail lights might be integrated.
