Car Analogy Please writes: The GTbyCITROËN has become the first (known) real-life car to be originally born in a video game. The Gran Turismo 5 Prologue car has been unveiled for real at the Paris Motor Show. The GTbyCITROËN is the product of a partnership built up during the creation of Gran Turismo 5 Prologue. Takumi Yamamoto, from Citroen and Kazunori Yamauchi from Polyphony Digital Inc, the games developer were inspired by each others industries to design a concept car for the game that then flowed further into the real-world. The game version of the car mirrors the real-world performance of the concept.
