In all probability the Audi A4 would not be receiving its RS version. The project that had been rumored seems not to have made it further. Even though the RS4 is indeed a very competitive model, yet not being able to see it any further would sure bring many a auto lover to feel sad.
Audi would sure come up with some nice surprise soon and it is wait and watch that we have to adhere to for the time. Audi has its sight fixed on the RS6 and most probably that is what they would focus on developing upon. This one is supposed to have a 4.0 liter twin-turbo V8 engine that will deliver around 600hp. The feature is similar to that of the RS7 which also needs to be pondered upon.
