Sadly, there's little chance of Audi ever green-lighting it.
Despite having the RS4, RS5, RS6, and RS7, not to mention the RS Q3 and TT RS, it doesn’t seem likely Audi will push ahead with an RS8. And that makes us sad. Especially when you consider it could look like this. Design RM has knocked up a rendering of what would be Audi’s answer to the Mercedes S65 AMG, and we can’t help but feel there would be plenty of interest in this sexy hi-po sedan. Unfortunately, until Audi feels likewise the RS8 will remain a thing of fantasy.
