Chevrolet appears to have some big changes in store for the next Malibu as shown by some spy shots. A huge change is with the greenhouse as the mule gets a sleek roofline that slopes downward dramatically to a shorten rear end. The speculation is that Chevrolet is taking some ideas from Chrysler 200 and Ford Fusion to inject some European design into the next model. We can't tell much about the front aside from the fascia appearing to stay the same.
There are mechanical changes in store as well. Chevrolet could drop the 2.5L four-cylinder for a smaller four-cylinder with a turbocharger to increase fuel economy.
