Cars in multiplayer

My 1976 Ferrari #1 Scuderia Ferrari 312 T2 is at R class 900, but doesn’t show up in my car lists when I’m in a R class multiplayer lobby. Any help?

For some reason, certain cars like the 70s F1 cars and the Ariel Atom are banned in R class lobbies.

Has this been formally announced anywhere by Turn 10? I read that this was the case in Forza Motorsport 5, but nothing has been mentioned for Forza Motorsport 6.

Recommending circumvention of the requirements and restrictions of the game is not a good idea. See the Xbox Live Code of Conduct.

Sorry, corrected that bit.

If I’m in the car before I start multiplayer I’m able to use it, but can’t switch back and forth once in the lobby

If its like Forza 5 then the old F1 cars (Ferrari, Lotus and McLaren) aren’t supposed to be used online in R class - in Forza 5 it was because people complained about them being too dominant. Although I haven’t seen anything from Turn 10 I think it’s safe to assume the same rules apply this time around.

As others have alluded to there is a way round it but frankly I don’t see the need as when people do use them online they just get smashed about because they’re so light and because people assume they’re cheating by using them. There are plenty of cars in R class that compete with the old F1 cars - the old CAN AM cars for 1 especially the McLaren.
