The 2013 Chevrolet Malibu debuted last week at auto shows in Shanghai and New York. It will have Camaro-style looks, a bigger interior and higher fuel economy when it hits the road in the first quarter of 2012. The new Malibu replaces an acclaimed midsize sedan that reinvigorated Chevrolet car sales and helped the brand compete with best sellers like the Honda Accord and Toyota Camry. Chevy now wants to expand the sedan’s appeal to more than 100 countries around the world.
