If you search the Internet you will find lots of reviews of the new M5 but here's what Autocar thought. On the whole it seems that the M5 has made the transition to turbo power with little noticeable drop in driver entertainment value which is very high praise because the old S85 engine was a masterpiece of instant throttle response.
There also seems to be a return to the E39 values of performance combined with comfort that was missing with the E60, no doubt partly to do with the switch from SMG to DCT.
Verdict : Best M5 yet.
