Saturn's new small, entry-level Astra hatchback replaces the Ion. The standard engine is a 140-horsepower, 1.8-liter four-cylinder. Standard safety features will include side and curtain air bags and active head restraints. Electronic stability control will be standard on two-door models and optional on four-door versions.

CR's take. The Astra is a rebadged Opel Astra, which was designed in Germany and built in Belgium, and was Europe's best-selling car in 2006. Our 2008 new cars review finds that this version retains its European character and is more capable and refined than the Ion.
