Mercedes-Benz debuted its dramatic Vision CLS concept car today during news media activities preceding the opening of the Greater L.A. Auto Show. The four-door CLS design study is the first vehicle to combine the emotional design of a coupe with the comfort and functionality of a sedan. Mercedes-Benz has decided to add the CLS to its broad portfolio of high-quality products. When it arrives in the U.S. market in 2005, the CLS500 will be powered by a five-liter V8 engine, and its standard equipment will include a seven-speed automatic transmission, DC Airmatic air suspension and active-curve bi-xenon headlights.
