"forza motorsport 3" includes more than 400 customisation cars (more than 500 cars in the "ultimate collection" version) from 50 manufacturers and more than 100 race track variations with the ability to race up to eight cars on track at a time. these cars vary from production cars to race cars such as those from the american le mans series. at the e3 2009 microsoft press conference where the game was first showcased, turn 10 unveiled the rewind feature (much like the codemasters "flashback" feature on "", "f1 2010" and "dirt 2"), which allows the player to turn back time to fix previous mistakes made on the track. the rewind feature has no limit on how many times it may be used but afterwards, the player must wait 30 seconds before being able to rewind again. it is also the first game in the franchise to feature a cockpit camera and to have sport utility vehicles.
