Every 2008 Saturn Astra is equipped with a 1.8-liter four-cylinder engine paired to a standard five-speed manual transmission or an optional four-speed automatic. This powertrain makes 140 horsepower and 126 lb.-ft. of torque, competitive if not class-leading figures. Saturn estimates 27 mpg in the city and 34 mpg on the highway. Electro-hydraulic steering and four-wheel-disc ABS are standard; the XR includes stability control and 17-inch wheels. Three-door models can also be equipped with 18-inch wheels wearing 225/40 performance tires.
