This bigger and more powerful Chevy Malibu helps pave the way for a rumored size increase and switch to rear-wheel-drive for the 2009 Impala. More important, the new Malibu replaces today's dowdy rental-car-special with a dynamic, more desirable family sedan. Given its basis on the entertaining Pontiac G6 and impressive Saturn Aura foundation, Chevy loyalists will find plenty to like about the redesigned Malibu. Whether it can win Honda, Nissan and Toyota intenders remains to be seen.
