The Top Gear Test Track, located at Dunsfold Aerodrome in Surrey, England, is a renowned racing circuit primarily associated with the BBC's popular motoring show, Top Gear. Originally a Second World War airfield, Dunsfold Aerodrome was repurposed for civilian use and eventually became the home of the Top Gear Test Track in the early 2000s.

The track's layout is deceptively simple, consisting of a series of challenging corners and straights designed to test a vehicle's handling, acceleration, and braking capabilities. Notable corners include "Gambon," a fast, sweeping left-hander named after late racing driver and actor Sir Michael Gambon; "Follow Through," a tricky esses section; and "Hammerhead," a tight hairpin bend that demands precise steering. The track's relatively flat surface and lack of significant elevation changes contribute to its focus on pure car performance rather than driver skill in navigating complex terrain.

While not a formal racing venue hosting sanctioned motorsport events, the Top Gear Test Track has become a cultural icon in the automotive world. Its primary function is for testing and reviewing a wide range of vehicles, from budget hatchbacks to high-performance supercars. The "Star in a Reasonably Priced Car" segment, a staple of the Top Gear show, sees celebrities complete timed laps around the track, providing a benchmark for comparison and entertainment. The track is also used for various challenges and stunts, adding to its unique appeal.

What sets the Top Gear Test Track apart is its association with the show's distinctive brand of humor and irreverence. Its unpretentious design, combined with the show's witty commentary and dramatic visuals, has made it one of the most recognizable and beloved racing circuits in the world, despite its relatively short length and lack of formal racing credentials. The track's popularity stems from its ability to showcase the performance of cars in a relatable and entertaining way, making it a true icon of automotive culture.
