An all-new diesel engine option makes its debut for the 2005 Jeep Liberty. Exterior appearance changes this year include a new front fascia, grille, foglamps, fender flares and body side moldings. Interior upgrades include relocated power window switches, new instrument panel cluster graphics and trim bezels and improved seat comfort. The Renegade model gets a flatter hood, taller grille, off-road foglamps and taillamp guards, as well as functional rock rails and four skid plates. A new six-speed manual transmission replaces last year's five-speed unit.
