The 2009 Saturn Aura lineup shuffles some trim levels and model names and adds some new features. This midsize sedan shares its basic design with the Chevrolet Malibu, Pontiac G6, and Saab 9-3. Aura offers base XE, uplevel XR, and gas/electric Hybrid (formerly Green Line) models. XE and new-for-2009 XR 4-cylinder models have a 169-hp 2.4-liter 4-cylinder engine. XR V6 models have a 252-hp 3.6-liter V6. All XE and XR Auras have a 6-speed automatic transmission. This transmission replaces a 4-speed automatic on 4-cylinder Auras. The XE V6 model with its 219-hp 3.5-liter engine has been discontinued.

The Aura Hybrid has a 2.4-liter 4-cylinder engine that pairs with an electric motor for 164 hp total. This hybrid can shut off the gas engine at a stop, but it cannot run solely on electric power. It uses a 4-speed automatic transmission. Available safety features include ABS, traction control, antiskid system, curtain side airbags, front side airbags, and GM's OnStar assistance. Leather upholstery with heated front seats is available, as is a sunroof. Newly available for 2009 is a wireless cell phone link.
