Like its predecessors, the RS6 likes to play the smoothie as much as the supercar slayer. Even on steel springs, the ride is far more compliant than that of the E63 or BMW M5, coping well with poor surfaces, although those vast wheels cause the odd wince when they crash into a pothole. The same is true of the engine, which is docile and muted at low to medium revs, with the gearbox shifting smoothly and early when youre simply taking it easy.
