It seems that Gran Turismo 5 will be going to extremes in their latest racing sim, according to reports from UK based website, Auto Express. At last week's Nurburgring 24 hour race, Kazunori Yamauchi, Creator of Gran Turismo, alongside driver Owen Mildenhall, raced two Lexus IS F with an on board computer that lets racer load lap times exactly into Gran Turismo 5, and then attempt to beat those lap times in game.
Apparently on upcoming Toyota and Lexus models, the computer system will be an optional upgrade that uses GPS to track the route, as well as an on-board computer that measures everything from g-force, to engine revs, as well as the speed of each individual wheel. These times can be loaded into the PlayStation 3 through USB and then be translated to the game to race for a better lap time in-game.
There was also an extensive run of the Nurburgring's 15.2 mile Nordshleife 24 hour circuit demoed by Mildenhall, which also included a full day and night cycle of the track in real time. Mildenhall also complimented that the track in game felt exactly the same as the real thing, down to every detail, including the thrill of the night racing.
Sounds like Gran Turismo 5 will be incredibly extensive, and even take simulation to the peak of extreme, allowing racers to use the game as an actual tool to improve driving ability. Hopefully We'll still see Gran Turismo 5 in time for its speculated release date of sometime this upcoming Fall.
