The Top Gear test track is used by the BBC automotive television programme Top Gear. It is located at Dunsfold Aerodrome in Surrey, United Kingdom. The track was designed by Lotus Cars as a testing facility, with many of its Formula One cars tested there. It is used to test both cars and drivers seen on the programme, mainly in Power Laps and Star in a ... Car. For the 23rd series of Top Gear the track was expanded with a rallycross section for the "Star in a Rallycross Car" segment, but it was abandoned at the end of series 23.
