Forza Motorsport 3 will include over 400 cars from 50 manufacturers and over 100 tracks. [1] New additions to the game include an in-car driving view, one button assisted driving, and vehicle rollover. Also included will be the ability to create in game videos and upload them to the Forza Motorsport website.



A new single-player season mode will put you through a completely personalized racing calendar that includes more than 200 different events, including Circuit, Oval, Drag, Drift and Timed Events. Now two calendars will be the same.



In addition, the online multiplayer mode gains an all-new game rules editor. New Xbox LIVE scoreboards will display not only the greatest racers but also the most prolific car tuners and painters in the community.



At the E3 2009 Microsoft Press Conference, Turn 10 mentioned a rewind feature, but did not say exactly what it did. It was later revealed on G4's day 1 E3 2009 coverage that the rewind feature will allow players to turn back time to fix previous mistakes made on the track. The rewind feature has no limit on how many times it can be done or time between rewinds.[2]



During another interview at E3 2009, game director Dan Greenawalt revealed that besides improvements to the A.I. and physics, the new graphics engine features ten times more polygons in each car model and a texture resolution that is four times higher than before.
