Gran Turismo HD Concept

Gran Turismo HD Concept is a sim racing video game demo developed by Polyphony Digital and published by Sony Computer Entertainment for the PlayStation 3. It is the first installment of the Gran Turismo racing video game series to be released on the console. It was made available as a free download which was released on the PlayStation Store on December 24, 2006. A Blu-ray Disc version, called "Install Disc", was released in Japan in limited quantities in September 2007. The game was intended to be a sneak preview, in the likes of Gran Turismo Concept, preceding the release of a full version title, but the Gran Turismo HD project was canceled and replaced by Gran Turismo 5 Prologue.
