Major changes included: The first generation Liberty marked Jeep's introduction into the compact SUV market. With bold styling and robust construction, the Liberty held much promise for the brand. A unibody-on-ladder frame chassis made the Liberty a vehicle worthy of the Jeep nameplate. Three trim levels were offered for the Liberty, including Sport, Limited and Renegade (later replaced by Latitude). The Liberty received three all-new engines, including a 150-hp 2.4-liter four-cylinder, 210-hp 3.7-liter V6 and even a Mercedes-Benz-sourced 2.8-liter turbo diesel four-cylinder producing 160 horsepower and 295 lb-ft of torque available in Sport and Limited models from 2005-2006. The Liberty came with either a full-time Selec-Trac or part-time Command-Trac 4WD system.
