Los Angeles – A car with extended, elegant lines which can change its form at the touch of a button and adapt to the requirements of its owners at any time – this is the automotive vision that Mercedes-Benz is presenting at the Los Angeles Design Challenge, which is being held for the fourth time as part of the 2007 L.A. Auto Show. When required, this Mercedes of the future can take on the form of a fast highway cruiser, quickly metamorphose into a compact city car, or become a roomy one-seater or economical two-seater, depending on the transport capacity needed. This is made possible by the magnetic control elements of the SilverFlow, a futuristic study by Mercedes-Benz, which take just seconds to configure the car required from tiny metallic particles.
