2007 Saturn Aura unveiled

General Motors has unveiled the 2007 Saturn Aura -- a production version of the concept shown last year. Uplevel models feature GM's first application of a new six-speed automatic transmission mated with the 3.6L DOHC V-6, creating a powerful yet fuel-efficient package. Later in the 2007 model year, Saturn will offer the Aura Green Line, a 2.4L Ecotec-based hybrid that will use a powertrain system similar to the Vue Green Line. It marks the first application of a hybrid powertrain in a GM passenger car. When it goes on sale late this summer, the Aura will be available in two trim levels: the entry XE model and uplevel XR. Each model is well-equipped, with premium features and interior materials among the best in its segment.
