New or Significantly Altered Models

2013 Chevrolet Malibu
Malibu is all-new for the 2013 model year. Although the overall length is roughly the same, the new model is 2.5 inches wider and has a 4.5-inch shorter wheelbase. The first model on sale is the Malibu Eco with a 2.4l four-cylinder gasoline and 15kW electric motor hybrid powertrain. The Malibu LS, LT, and LTZ models follow and are powered by a 2.5l four-cylinder gas engine. From the a-pillar forward, the Malibu retains many of the same lines. The aggressively styled rear end has more pronounced fenders and four square taillights. The interior loses the two cockpit look in favor of a more subtle two-tone dash and less prominent center stack.
2013 Chevrolet Spark
The Korean built Spark becomes the new entry-level model in Chevrolet's US lineup. The small Spark is about 15 inches shorter than the Chevrolet Sonic. A 1.2l four-cylinder engine produces 85-bhp and can be paired with either a five-speed manual or four-speed automatic transmission.

Updated Models
