Mercedes-Benz Concept Style Coupe revealed ahead of China auto show

Mercedes-Benz is previewing its eagerly anticipated CLA sedan at an event in Los Angeles this week before providing a more detailed look at the Beijing motor show with the unveiling of the latest in a long line of concept cars, the 2.0-liter, 208-hp, four-cylinder-powered Concept Style Coupe. Pictured here officially for the first time, the heavily sculptured four-door reveals the dramatic appearance that the next junior Mercedes-Benz sedan will carry into North American showrooms in 2013. Advancing the look first established on the F800 Style concept wheeled out at the 2010 Geneva motor show, the Concept Style Coupe is clothed in a four-door body that makes extensive use of concave and convex surfaces to provide its exterior with what Mercedes-Benz design boss Gorden Wagener describes as “an almost fluid appearance and constantly altering depth.” The car has a large gaping grille known to insiders as a soft-nose treatment, striking headlamps with LED graphics, a heavily curved roofline, a shallow glasshouse, a high waistline, frameless doors and a trio of sharply creased lines along its flanks.
