Any car with 4 wheel independent suspension, and the appropriate dimensions, is an IFMAR legal touring car, doesn't matter whether it is 4WD, FWD or RWD.
The 2WDs even have a lighter weight limit under IFMAR regs, since they have less weight in the drive train. The reason behind the weight limit is to discourage exotic materials, not give an advantage to one platform over another, and since 2WDs are naturally lighter, that's fair.
In slower classes, on certain tracks, 2WDs are the ticket.
