This is the full list of "official" Power Lap times on the Top Gear test track.
[2][3][4][5][6][7][8][9][10] Whenever a non-qualifying vehicle is raced, the time is compared to the official power laps but then removed from the board.
For example, the Ferrari FXX owned by Michael Schumacher (1:10.7) was taken off the board because it both failed to meet road legal standards and used slick tyres, and the Caparo T1 (1:10.6) was removed because its front wing was too low to drive over a Speed bump.
This indicates that The Stig and the Top Gear team consider that the prevalent weather conditions have affected the lap time or car's performance.
The time on the board is not changed: e.g. 1:50 MM (Mildly Moist) is deemed to be equivalent to 1:48 on a normal dry track.
