The Liberty infused bold engineering advances like an independent front suspension and a new 3.7L V6 to replace the longstanding 4.0L I-6 engine.

In 2004, the Jeep_® Brand offered a “stretched” version of the TJ, Wrangler Unlimited. Ten inches longer in wheelbase (103-inch) and 15 inches longer in overall length, the Unlimited offered two inches more rear leg room, more interior space, and greatly enhanced on-road handling.

The increased wheelbase offered more refined on-road comfort, as well as versatility and increased towing capacity to 3,500 pounds when properly equipped.

The all-new Grand Cherokee (WK) debuted in 2004 as a 2005 model. This revamped Grand Cherokee combined power, luxury and a significantly quieter, more comfortable ride.

The ground-up transformation continued with a choice of three power plants including the mighty 330-horsepower 5.7L HEMI^® V8 engine. The 2006 Jeep_® Grand Cherokee SRT8^® featured a 6.1L HEMI V8 with 420 horsepower and 420 pound-feet of torque, 20-inch lightweight forged wheels and four-piston Brembo brakes.

The 2006 Commander was the first seven-passenger Trail Rated^® Jeep_® 4x4 vehicle. Based on the ‘05 Grand Cherokee platform, the boxy Commander was only slightly longer than the WK (two inches), but a three-inches-higher stepped roofline and stadium-style seating arrangement allowed for an extra row of seats in back.

Basic power and drive train offerings were the same as the Grand Cherokee (WK). As with most Jeep_® Brand 4x4 models, the Commander carried the Jeep Trail Rated^® badge. To be Trail Rated, a vehicle must meet performance standards in traction, articulation, ground clearance, maneuverability and water fording.

The vehicle is front-wheel-drive with a choice of two available electronically controlled 4x4 systems for all-weather use: Freedom Drive I, a full-time system for on-road use, or Freedom Drive II^®, that is off-road capable.

The 2007 Wrangler model's signature round headlamps, iconic seven-slot grille, solid axles, removable doors, exposed hinges, fold-down windshield, innovative removable and convertible tops all honor Jeep_® Brand heritage while signaling new levels of capability and versatility.

The Wrangler is certified with a Jeep_® Trail Rated^® badge, verifying that the vehicle is able to perform in a variety of challenging off-road conditions identified by five performance categories: traction, ground clearance, maneuverability, articulation and water fording. In short, the Wrangler is designed to satisfy hardened off-road enthusiasts and luxury SUV drivers alike, with minimal compromise to either extreme.

Wrangler is the ultimate, all-American 4x4 freedom machine–the Jeep_® Brand’s modern-day descendant of the original, heroic Willys MB.

Jeep_® Brand engineers sought to improve the Liberty vehicle’s on-road refinement and strengthen its off-road abilities. As a result, all-new independent front and five-link suspension systems, along with an all-new available Selec-Trac^® II Full-Time 4x4 System were developed, giving the Liberty refined on-road handling without compromising the vehicle's off-road attributes.

In 2011, the Jeep_® Brand celebrated its 70^th Anniversary with a special edition of the Jeep Liberty. This distinctive vehicle was available with a distinctive exterior paint color (Bronze Star Pearl), 70^th Anniversary badging and more.
