A UK car magazine recently did a 0-100-0 group test to determine "Britains Fastest Cars", the results of which are posted below. Unfortunately they did not include the M5. (Perhaps they couldn't get hold of one judging by current UK delivery times!).
As a future M5 owner (delivery due March 2001) I would be interested to hear from anyone who has done such a test with their M5 or knows of any other magazines that have done similar tests.
The cars were all tested one up, with half a tank of fuel and a small datalogger attached.
