Is it just me or is it impossible to see the leaderboards or personal worldwide rankings anywhere but on screen at the end of a race? I have attempted to look for rankings on the console, the internet etc. but cannot find anything. I would like to be able to see where all of my friends rank and where I rank for each class I have raced without having to finish a race first.
In game you can go to the rivals screen and hit up which ever class and track combination you are interested in and hit the Y button to bring up the leaderboards.
On the internet, go here: Forza.net: The official website of the Forza franchise
As long as you are logged in using your game account you can see where you and your friends rank.
All the leaderboards are in the Rivals section except for drag racing. Drag leaderboards can be seen from freeplay. You change the game mode to drag, class to any. You need to be in the class of car you are wanting look up. Then you just go to select track and can view the LB from there.
They should put your Rivals rank on the track you raced after your name in the results screen in multiplayer. That would be cool. It would probably encourage cleaner driving.
