Citroën just revealed their new concept car, unofficially called the "Citroen GT" and officially called "GT by CITROËN," here at the Paris Auto Show and it's hot - it's also supposedly the first car "specifically designed to bring the virtual and real worlds together." What's that mean? Well, apparently visitors to the show can actually drive the car in a true to life simulator on the Citroën stand. But that's not the cool part. The cool part is that it's a joint venture between Citroën and Polyphony, the makers of Gran Turismo.
