We’ve already informed you about the upcoming Gran Turismo 5 for Playstation3 and some of the cars specially featured in this game. Now what’s better is to build the hype up step by step by watching official teasers that will be coming before the game launch! Apparently in this version of the GT, Mercedes SLS AMG has stole the show! This yet-to-be-released supercar is so special that the Yamauchi, maker of Gran Turismo, had to took for a drive around Nurburgring before putting it in the game! He certainly didin’t do so with Koenigseggs and Ferraris!
