That simple comment really made me laugh!

If I were in charge Id drop the hammer for the V-10 to be fitted in the RS5 seeing that this is a higher model than the RS4 anyway! but we all know Audi isn`t going to do that.

On top of that anything north of 480hp for the RS5 would make it more powerful than the V10 R8 which is said to get 480hp.
