The i.materialize 3D printing folks were tapped by Citroën to help build a working, full-size Citroën G, this being an imaginary car that had previously only existed in the virtual confines of the Gran Turismo 5 racing game. They did so, and actually drove the car around the streets of London.
The concept car itself is an impressive racing monster, a virtual design transposed to reality with quite irrational proportions. The car remains fully functional with butterfly opening doors and passed top speed tests at about 200km/h on a racetrack.
The architecture was made from a tubular aluminium racing chassis with carbon fiber body parts around. The engine was taken from a competition car with the corresponding harassing sound.
The exterior design emphasizes speed with a very aggressive racing look, while the interior was designed to create an impression that the cabin is literally on fire. For the GT concept, most of the interior was 3D printed.
