— After spending billions to revamp Chevrolet and Cadillac, General Motors has turned $3 billion of attention to Saturn.Saturn's newest addition, a sporty roadster called the Sky, which is to be a “halo” vehicle for the brand, will make its debut at the North American International Auto Show in Detroit, the Associated Press reported on January 6. The car is scheduled for production in 2006 at GM's Wilmington, Delaware, assembly plant and is expected to be priced under $25,000, the report continued.AP also noted that Saturn also plans to add a new mid-size car and a larger sport/utility vehicle by the end of 2006, doubling the size of its range. Saturn is set to show a concept vehicle called the Aura at Detroit that company officials say provides a sneak preview of its upcoming mid-size sedan."This is an aggressive move and growth strategy we're putting behind the brand," Saturn general manager Jill Lajdziak told the Associated Press. "What people want from us is a growing portfolio and a dynamic design."AP said Saturn's current lineup consists of three models: the Vue SUV, the Ion compact sedan and coupe, and the Relay minivan.
