Having long shed its image of producing boxy cars, the Volvo S60 Concept demonstrates that the designers at this Swedish automaker are taking the company's styling to new heights. There's no mistaking the Scandinavian heritage in this S60. The headlamps, for instance, throw light off in a pattern that resembles Viking longships, and the interior that uses light-colored wood accents. The S60 promises to be even kinder to the environment thanks to its direct-injected 1.6-liter 4-cylinder engine that produces 180 bhp.
