The 4 pot feels great, is very well mounted, superbly sound insulated, and all this will have an impact on the drivers perception of refinement but the laws of physics simply preclude an inline 4 being smoother than an inline 5. |
I don’t disagree with any of that - but what else matters other than driver perception? Go and drive a 2016 D4 and D5 back to back and then tell me if you think I’m wrong?
