Inspired by styling from the Dakar and Jeepster concept vehicles, the Liberty was intended as a replacement for the discontinued Jeep Cherokee. The Liberty also marked a few firsts for Jeep. It was the first Jeep vehicle to use rack and pinion steering. It's also the first Jeep to use the two then-new PowerTech engines; the 150 horsepower (110 kW) 2.4 L straight-4, which was discontinued in 2006, and the 210 horsepower (160 kW) 3.7 L V6, as well as a 2.8 L VM Motori turbo diesel (2005-2006 only) for the CRD versions. However, the Liberty was not the first Jeep vehicle to use an independent front suspension, as the Jeep Wagoneer first used it in the 1963 model. But, that independent front suspension was limited to four wheel drive versions and, even then, was a short lived option. In addition, the Liberty was nominated for the North American Truck of the Year award for 2002.
