Gran Turismo 4 (2004)
Kazunori Yamauchi's Encyclopedic 700-Car Automotive Museum and Technical Peak on PS2
Gran Turismo 4 is a 2004 racing simulation directed by Kazunori Yamauchi at Polyphony Digital for the PlayStation 2. Shipped on a dual-layer DVD-9 containing more than 700 cars across 80 manufacturers—from the 1886 Benz Patent-Motorwagen to Le Mans prototypes—alongside the Nürburgring Nordschleife, B-Spec management, Photo Mode, and 1080i output, it sold 11.76 million copies worldwide.
A Century of Motoring History and the Green Hell
Conceived by Kazunori Yamauchi as an interactive museum of automotive culture, Gran Turismo 4 pushed a dual-layer DVD-9 to capacity with over 700 vehicles representing 80 marques across 119 years of engineering—from Karl Benz's one-horsepower 1886 three-wheeler and Jay Leno's Tank Car to Group C prototypes. Polyphony Digital conducted exhaustive GPS and photographic surveys to reconstruct 51 circuits, crowned by definitive console depictions of the 20.8-kilometer Nürburgring Nordschleife and Circuit de la Sarthe, complete with real-time 24-hour endurance races. Revised suspension and weight-transfer physics tempered its predecessor's forgiving slides into far more demanding braking discipline.
B-Spec Strategy, Photo Mode, and 1080i Hardware Wizardry
Although planned online play was excised late in production to prevent further delays—later tested separately in Gran Turismo 4 Online—the retail release pioneered two features that reshaped racing games. B-Spec mode shifted players from behind the wheel to the pit wall, directing an AI driver's overtaking aggression and tire stints during grueling endurance events, while Photo Mode simulated aperture and shutter speed before exporting JPEGs directly to USB flash drives or printers. Remarkably, Japanese and North American builds squeezed 480p progressive scan and upscaled 1080i high-definition output from 2000-era PS2 silicon, propelling global sales to 11.76 million copies.
