WIRELESS technology from Carrera provides even more fun and freedom at the race track. Modern infrared technology is compatible with all Evolution PRO-X, Evolution and Exclusiv race track systems. Up to four cars can be controlled simultaneously at a range of almost 10 feet. And because of the unique hand controller design, a racer can be positioned almost anywhere in the room. The decorative MOBIL-tower which serves as infrared receiver is a must for every Carrera enthusiast.
