Blurring the lines between midsize and full-size, the redesigned 2008 Chevrolet Malibu gets a longer wheelbase than and almost identical head and legroom measurements as the supposedly larger Impala. Based on the same platform as the Pontiac G6 and Saturn Aura, the new Malibu is basically a Chevy flavor of those two cars offered in LS, LT, LTZ, and, to be introduced later, hybrid trim. Gone is the sporty SS and the funky Maxx hatchback, replaced by a sleek sedan wearing the new face of Chevrolet: a dual-port grille. A midsize Chevy sedan on a list of studs? We’re either crazy, or the Malibu promises to be one of the best four-door domestic competitors to hit the streets in quite some time.
