the Cruiser as a concept only, never making it available for purchase. The intent was to attract younger buyers to the stock model and to demonstrate the viability of aftermarket modifications. Sixth generation (2004) The Malibu name was moved to GM's new Epsilon platform based on the 2002 Opel Vectra C for 2004. The Epsilon-based Malibu came in two bodystyles, a standard 4-door sedan and a 5-door Malibu Maxx hatchback (the first mid-size Chevrolet hatchback since the 1989 Chevrolet Corsica). The Malibu Maxx has a fixed glass roof panel over the rear seats with a retractable sunshade, and an optional glass panel sunroof over the front seats and was similar in execution to the Opel Signum, a large hatchback derived from the Vectra C. Base power for the sedan came from a 2.2 L Ecotec L61 I4 producing 144 hp (108 kW). LS and LT trim sedans and Maxx models originally came with a 3.5 L 201 hp (149 kW) High Value LX9 V6. The SS sedan and Maxx models were powered by the 3.9 L High Value LZ9 V6. For 2007, the LX9 was replaced with the LZ4 V6, which in the Malibu produced 217 hp (162 kW). This was the only engine available to private buyers in the 2008 Malibu Classic. The L61 Ecotec was also updated for the 2007 model year with many improvements. A remote starter was also available, which was introduced on several other GM vehicles for 2004. The sixth generation of the Malibu initially debuted with a front fascia design featuring a wide grille split horizontally by a prominent chrome bar that ran the entire width of the car, shared ultimately cross-brand. For 2006, the chrome bar was removed, and the grille itself was made smaller. As with all cars across GM, the car also carried GM badges near the front doors. The Malibu Maxx was discontinued after the 2007 model year, the Malibu sedan remained in production for the 2008 model year, known as the Malibu Classic. The cars themselves bear Malibu badges, unlike the past generation Classic. Three models were available: the V6-engined LT and LS, and a four-cylinder LS version. Only the V6-engined LT was available to private buyers, with the LS versions only built for fleet sales.
