Jeep Wrangler


There is a vehicle that all people identify as Jeep generations after generations: the Jeep Wrangler. This mini SUV has a captive market since its debut in 1987, facing major updates every ten years.

In 2007, Jeep Wrangler is available in the following trims:

Wrangler is now powered by 3.8 liter V6 engine with 202 horsepower, substituting the original 190 horsepower straight-six of its predecessors, improving gas mileage that ranges between 17 and 19 in city and highway respectively.

Another improvement can be perceived in the vehicle's larger interior and extra open-air options, including a new modular hardtop, although the new slanting grille front is not convincing too many of the loyal Jeep fans.

General space improvement includes these characteristics:

  • Front headroom: 41.3 (1049.0 mm)
  • Front legroom: 41.0 (1041.4 mm)

  • Maximum cargo width at
  • Swing gate opening: 58.7 (1491.0 mm)
  • Distance between wheelhouses: 44.7 (1135.4 mm)

However, the Wrangler 2007 looks more traditional than previous models because of its old-style round driving lights underneath the headlights that recreate the original Army Jeeps from which Wrangler is a replica.

Mike Donoughe, Body-on-frame Product Team Vice President said "Reengineered and redesigned from the ground up, the 2007 Jeep Wrangler is the most capable Wrangler in its 65-year history, with more ground clearance, better wheel articulation and advanced off-road hardware, Jeep Wrangler is designed to tackle the toughest off-road obstacles".

Indeed, Jeep Wrangler's ground clearance is now combined with rear overhangs and a short front, great for challenging driving through off-road trails. Wheels and tires have been also enhanced with the following specs:

  • Standard wheels, any trim, in painted steel 16 x 7.0
  • Optional wheels in painted cast aluminum 16 x 7.0
  • Rubicon standard wheels in machined cast aluminum 17 x 7.5

Jeep Wrangler is a vehicle equipped with electronic-disconnecting front stabilizer bar, known as Active Sway Bar System (ASBS), empowering additional wheel travel in the toughest terrain.

In 2007, the Wrangler offers more stopping power than ever before thanks to its exclusive 16-inch four-wheel-disc anti-lock brakes (Stopping PowerNew), as well as off-road anti-lock-braking feature for improved performance on arid and uneven surfaces.
