The 2016 Chevrolet Malibu is all-new from the ground up, with a longer wheelbase and more interior room for both front- and rear-seat passengers. It is also 300 pounds lighter, which pays dividends in increased fuel efficiency. My test drive examined the Malibu with the all-new 1.5L Ecotec turbocharged engine from the perspective of both a fleet manager and a company driver.
