I recently drove the new RS6 and whilst it is a fantastic car and a nice place to be, it wasn't for me. It red lines at 6.5k and it was like driving a big diesel; tons of low down grunt but just when you wanted things to start happening, it hit the limiter. I felt like I was always having to short shift to get it moving. Bloody quick though, but not the power delivery I really want in a 'toy'. Strangely, I drove a new RS4 immediately before the RS6 and I can't for the life of me remember anything about what it was like to drive. A very quick car by all accounts but, to me and I don't know why, eminently forgettable.
