The elegant Aura sedan series gets more refined this year with the introduction of the high-end XR version, with a four-cylinder engine. All versions equipped with this engine also get a new six-speed automatic transmission for a better power output and fuel savings. Only the hybrid version keeps the four-speed automatic transmission. Saturn has also chosen not to offer the XE version, with 3.5-litre V6 engine, in 2009, though the 3.6-litre V6-powered XR version is available.
