With the Aura sedan concept and Sky roadster, Saturn is taking Oldsmobile's place in the "Chevy, Pontiac, Olds..." etc. lineup as GM's "import fighter." The Aura (not its final name) rides on the 112.3-inch wheelbase version of the Epsilon platform (Malibu Maxx and G6), but it will be the only Epsilon offered at-launch with GM's 3.6-liter twin-cam "high-feature" V-6. It will also come with a 2.4-liter/174-horse four, but a six-speed manual will be offered only with the six. Styling is based heavily on the Opel Vectra, with "sculpted surfaces and flowing horizontal lines," projector-beam trapezoidal headlamps and a panoramic sunroof, like the G6's. The concept's interior features snakeskin-like "Rustica" leather seats in navy and dark saddle and much attention to lighting, including a backlit instrument cluster, center vent switches and window and door switches, theater dimming, ambient overhead lighting, and illuminated door handles.
