Mercedes Autocross Rivals class

What class is the “Yas Benz There” autocross rival supposed to be? I just ran it in my C63 AMG in A-Class, but the leaderboard seems to show all B-Class cars. I don’t want to be “That Guy” who used an upper class car on an event, but I never got the usual message that says if your car is in the wrong class, it just went straight to the loading screen for the race. Now, to make it clear nobody need fear the pathetic time I set, but again I’d rather have my time removed if it was the wrong class.

Press X on the first screen (it will say in bottom right to press X for restrictions whn you are on the right screen).

Looks like its B class. Try to beat you r time in a B class car if possible.

Thanks SatNite, I’ll trade cars and get back to it later tonight
