Series 15 of Top Gear, a British motoring magazine and factual television programme, was broadcast in the United Kingdom on BBC Two and BBC HD during 2010, consisting of six episodes that were aired between 27 June and 1 August; the new series was promoted with a special trailer that made use of a clip published on YouTube. This series saw the replacement of the Chevrolet Lacetti by the Kia Cee'd as the Reasonably Priced Car.

The Top Gear test track located at Dunsfold Aerodrome in Surrey, United Kingdom was used by the BBC automotive television programme Top Gear. The track was designed by Lotus Cars as a testing facility, with many of its Formula One cars tested there. It was used to test both cars and drivers seen on the programme, mainly in Power Laps and Star in a ... Car.
