Gran Turismo HD Concept was the first installment of the Gran Turismo racing series to be released on the PlayStation 3. It was made available as a free download on the PlayStation Store. A Blu-ray Disc version, called "Install Disc", was released in Japan in limited quantities in September 2007. This 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.
