DETROIT — Volvo on Monday released the first exterior photo of the Volvo S60 concept that will make its debut at the upcoming 2009 Detroit Auto Show. 'It gives a clear indication of what the all-new Volvo S60 will look like when it is introduced during 2010,' Volvo said in an accompanying statement.The darkened image shows a coupelike roof line and what Volvo describes as 'new shoulder contours — a gentle double wave from the headlamps at the front to the taillamps at the rear.' The automaker said the concept is inspired by 'the Swedish coastline's cliffs and seas.'A second photo shows the car's cabin, which gets a floating center stack made of Orrefors crystal. 'We may well see interior features in crystal-like materials in the future,' said Steve Mattin, Volvo Cars' design director.Inside Line says: In stark contrast to the conservative S80, Volvo dances on the edge of daring with the S60 concept — at least from what we can make of it at this point. — Anita Lienert, Correspondent
