Top Gear/Test Track
Yellow: Dunsfold Park boundary, Red: Test track
1 Chicago, 2 Hammerhead, 3 Follow-through, 4 Bacharach Bend, 5 Gambon Corner
The Top Gear test track is located at the Dunsfold Aerodrome in Dunsfold, Surrery, England. Dunsfold Aerodrome was used by British Aerospace to flight test aircraft such as the Harrier Jump Jet. British Aerospace closed its facility in 2002 and it has since been renamed Dunsfold Park. The test track is just under 2 miles long and designed by test drivers at Lotus. Reviewed cars are driven around the test track by the Stig, Top Gear's very own tame racing driver, and the results are put on the Power Laps board.
Chicago is a steady-state corner that loads up the outside tires. Hammerhead is a tricky left-right designed to promote understeer. The Follow-through is a flat-out corner. Bacharach is a tricky corner designed to test brake balance. Gambon is a corner in which a badly setup front-wheel drive car will have trouble putting down its power. Gambon Corner was originally called "Carpenter's Corner," but was renamed in honor of Sir Michael Gambon. He nearly rolled his Suzuki Liana going through the corner during the Star in a Reasonably Priced Car segment of season one's episode eight.
