Ford, which unveils the 2013 Fusion on Monday at the North American International Auto Show, is hoping the car is as much of a game changer as the original Taurus was. Early looks show that the automaker is gunning for Camry and Honda Accord by channeling super-sports-car line Aston Martin, albeit with fuel economy. “We knew we needed a more premium design than our previous [Fusion] or our competitors’,” says Chris Hamilton, Fusion’s styling chief. The car is also the latest exercise in the One Ford global-vehicle program.
