Because it looks like it's an R8 thing.
Saw an article somewhere where the method of activating it on the R8 is to change what leads the battery's hooked up to, so there's not any liability on Audi's side because someone "accidentally" enabled Race Mode and wrapped themselves around a telephone pole or something. It involves ADS setting changes among other things, which is presumably why it's able to be shown in the ADS menu, but unless the underlying system's there and active then the setting wouldn't be able to take effect.
