 Currently (Sept 05) the fastest time around the Top Gear track is 1  min 18.9 seconds by a Maserati MC12. However there have been faster  laps which are not included on the board because they have not been  performed by road cars. The laps are: Aston Martin DBR9 (the racing  version of the DB9 GT car) 1 min 8.6 secs, Renault Formula 1 racing  car 59.0 seconds (in the wet) and a BAe Sea Harrier Fighter jet  which did the track in 31.2 seconds despite taking the final two  corners "somewhere over Kent".
