Fire up Gran Turismo 5 and youll be prompted to download another new update, version 1.03, weighing in at 149MB in size. No information has yet been released about exactly what this update contains (though the official PlayStation blog hinted at incoming damage tweaks earlier today, thanks @hankolerd), and GT5s online servers are currently offline until 11:00PM EST. Ill update this post as soon as more solid information is made available.
UPDATE: The servers are back online and an in-game news notice has been posted, but it mentions nothing of exactly what changes v1.03 contains. However, as can be seen in the online My Lounge options for an online race, a new Mechanical Damage setting is available for the event with three settings, as described by the scrolling information bar on the bottom of the screen:
None No mechanical damage.
Light Mechanical parts can be damaged, but will automatically be repaired after a short time has passed.
Heavy Mechanical damage will be more severe, and can only be repaired by making a pit stop. Damaged parts will be indicated with on-screen icons.
