The Saturn Astra replaced the Ion as the company’s entry-level model when it debuted in 2008. Available as either a three- or five-door hatchback, the Astra offers seating for up to five passengers, while providing a usable amount of cargo capacity. Competing in one of the most popular segments, the Astra offers a look that helps distinguish it among other compact hatchbacks. Powering the Astra is a 138-horsepower 1.8-liter four cylinder that is both peppy and fuel efficient. The Saturn Astra comes with a five-year/100,000-mile powertrain warranty and gets an estimated 30-32 mpg on the highway.
