now available to be downloaded to Gran Turismo 5: Prologue via a free patch. Simply load up the game and the download will begin almost automagically. Included in the patch are three new vehicles, the "GT by Citroen" concept car, the Ferrari California and the Lotus Evora. These cost 1 million, 500 thousand and 100 thousand in-game credits, respectively.
A number of gameplay enhancements have also been added, including changes to the penalty system, tweaks to difficulty levels and reward balancing. Controller responsiveness, sound volume and Drift Trial races have also been improved. Sadly there's no sign of trophies. Before you run off to download the update, be aware that "rankings, arcade time trial times, drift trial records, as well as vehicle-specific quick tune settings and custom key layouts will all be reset with the new update. Replay data created before the second update will no longer be viewable after this update."
