Recently been looking at S6 v10's and S8 v10's, currently got the A8 D3 4.2tdi with some tuning so not expecting much difference in performance but that v10 engine sounds great, anyone had any experience of moving from the tdi to the v10? I understand the running costs aren't comparible maintainance and economy is double that of tdi just want to see if any of you have any experience of moving from the dark side
