I think opinions vary of what an Audi RS should be like?
In my head I want an RS to be capable of being scary if not treated with total respect, others see it as the pinnacle of the Audi model range, the top transcontinental cruiser and being a bit bonkers isn't required. Some RS models are capable of carrying much of the straight-line speed through corners.
The prior generation 8U RSQ3 was firmly in the scary group, take excessive liberties and it would take a trip through the nearest hedge without a shadow of a doubt, waaay more power than the chassis could handle with an utterly epic 5 pot single turbo engine sat up front - unique to Audi RS. The best technique for rapid progress was power down the straights, shed the speed (those 8 pot Brembo calipers did that well) for corners, higher CoG and sub optimal suspension working against you and then boot it hard out of the bend. Properly addictive fun with a genuine aural soundtrack to match. Would an RS3 leave it behind? Yes, absolutely however having a super competent car isn't, for me anyway, much fun as I was about to discover with the fully loaded RS4.
The 2018 B9 RS4 with every option, was the transcontinental cruiser, fabulously good at everything, corners were dispatched like they simply were not there (DRC saw to that), it wasn't in anyway scary - well the steel brakes on mine were distinctly average so maybe a little. On reflection I wish I'd driven a standard car without DRC, maybe it would have felt closer to something scary when pressing and I'd probably have kept it.
The F3 RSQ3 retains the bonkers engine, substantially enhanced both mechanically and for power output but sat in a much more capable chassis so now it can get down the straights just as quickly, it has the new aluminium 6 pot calipers (also in the 2020 RS4?) and they shed speed well, the F3 corners much closer to 'flat', it's not perfect and remains a tad lary - it too would head for the hedge if provoked. perfect.
