<P> Due to the size of the list, only the top 20 are shown . See List of Top Gear test track Power Lap Times for the full list . </P> <P> The second most powerful production car ever featured on Top Gear, the 1001 PS (987 bhp; 736 kW) Bugatti Veyron, was taken around the track by The Stig in Series 12, Episode 4, after 3 years of waiting . However, it disappointed the team by only managing fifth place on the Power Board (currently 16th), an unexpectedly low position ultimately attributed to the car's kerb weight of 1,888 kg (4,162 lb), more than any of the four faster cars . In Series 15 Episode 5 however, the Stig took the 1,200 PS Super Sport version around the track in 1: 16.8, thus setting a new lap record . </P> <P> For the 1: 17.6 lap, the Koenigsegg CCX (written as "Koeniggggsenisseggsegnignigsegigisegccx2 with the Top Gear wing" on a much - longer magnetic strip, because none of the presenters were able to spell Koenigsegg) was fitted with an optional rear spoiler to provide downforce after The Stig spun the unmodified version off the track . The Stig allegedly recommended this modification, correctly predicting that the car would then be the fastest ever round the track, although Koenigsegg stated that the improvement was due to other adjustments . </P> <P> A "non-qualifying" vehicle is one that does not meet the presenters' requirements to remain on the board; that is, one that is not a "road car", which according to Top Gear means being: available to buy, fully road - legal (lights, indicators, registration, profile tyres, etc .), and street - worthy (i.e. able to negotiate a speed bump). </P>
