All models of the Aura were four-door mid-size sedans with faux-wood and metallic interior trim and accents. The XE trim features 17-inch wheels, a four-speed transmission and a 3.5-liter engine that produces 224 horsepower. The XR trim features 18-inch wheels, a six-speed transmission and a 3.6-liter engine that results in 252 horsepower. The XR trim also includes heated leather seats and a premium stereo system with a six-disc CD changer and auxiliary line-in.
The Aura Green Line features a 2.4 liter Ecotec engine with a linked electric motor that provides increased fuel efficiency compared to the XE and XR models, while creating only 164 horsepower.
The StabilTrak stability system provides computerized braking to individual wheels when the computer senses a loss of traction.
Saturn manufactured the Aura for model years 2007 to 2010, which was the last year of the company's existence. The Aura Green Line ended production in 2009.
