Re: 172 fastest cars around the ring
This list for the ring has some notable absences in it, particularly the McLaren F1 which was around the 7m11s mark and the BMW M3 CSL which was about 7m22s.
There are a few others missing before you even get to the 7m40s time of the Bugatti Veyron (Wheels mag, Australia) or the 7m42s of the Ford GT40 (Octane magazine).
There are also far quicker times for competition cars, the qualifying lap record is around the 6m11s mark and 6m25s for a race lap.
An 8c is alleged to have lapped in around 8m02s.
