The Saturn Aura is an excellent choice among midsize sedans. It's modern and fresh, with European character and aesthetic flair. Taut and responsive, it drives like a European family sedan, perhaps because it rides on a German Opel platform. The cabin is tastefully done and laid out and all the controls work very well. A wide range of engines and drivetrains is available for improved fuel economy or performance.For 2008, Aura comes standard with a 2.4-liter four-cylinder engine that earns an EPA-rated 22/30 mpg. Two V6s are available, including a 252-horsepower 3.6-liter V6, and both are smooth, sophisticated engines that make the Aura a very enjoyable car to drive. Introduced partway through the 2007 model year, the Saturn Aura Green Line features a gas-electric hybrid that uses a 2.4-liter four-cylinder engine and a 4 kW electric motor rated at 24/32 mpg.Click here to read more
