With GTbyCITROEN, a show-car presented at the 2008 Paris Motor Show, Citroen becomes the first vehicle manufacturer to cross over to the virtual worlds: An original take on a road car, GTbyCITROEN is a style replica of a vehicle from the digital world. The car is the result of a partnership between Citroen and Polyphony, designer of the driving simulation game Gran Turismo 5 on Playstation 3.
