The Brawner Hawk is a series of open-wheel race car chassis designed and developed by automotive mechanic and engineer Clint Brawner for U.S.A.C. Indy car racing, between 1965 and 1969. It successfully won the 1969 Indianapolis 500, driven by Mario Andretti.
The Brawner Hawk was originally powered by the naturally-aspirated {{cvt|255|cid|L|0|abbr=on}}, and later turbocharged {{cvt|159-162|cid|0|abbr=on}}, {{cvt|700|hp|kW}}, Ford Indy V8 engine, which also powered several Lotus and Coyote Indy race cars, and even a McNamara chassis. The chassis was lightweight, and only weighed around {{cvt|1400|lb|kg}}, giving it an incredible power-to-weight ratio.{{cite web|url=http://www.classiccarweekly.net/2022/04/08/1965-brawner-hawk-ford-indy-car/|title=Mario Andretti's Hawk-Ford|date=8 April 2022 |access-date=23 May 2022}}{{cite web|url=http://www.deansgarage.com/2011/mario-andrettis-1965-brawner-hawk-indycar/|title=Mario Andretti's 1965 Brawner-Hawk Indycar|date=3 February 2011 |access-date=23 May 2022}}{{cite web|url=https://www.motorsportmagazine.com/articles/us-scene/indycar/great-racing-cars-1965-67-brabhambrawner-hawk|title=Great racing cars: 1965-67 Brabham/Brawner Hawk|date=5 February 2016 |access-date=23 May 2022}}{{cite web|url=https://americanhistory.si.edu/race-cars/brawner-ford-hawk-no-2-1969#:~:text=Gift%20of%20STP%20Corporation,victory%20there%20for%2023%20years.|title=Brawner-Ford Hawk No. 2, 1969 - Mario Andretti's Indianapolis 500 Victory Car|date=14 December 2018 |access-date=23 May 2022}}{{cite web|url=https://americanhistory.si.edu/collections/search/object/nmah_694874|title=Brawner-Ford 'Hawk' racing car|access-date=23 May 2022}}{{cite web|url=https://www.oldracingcars.com/hawk/68/|title=Hawk 1968 Indy car-by-car histories|access-date=23 May 2022}}{{cite web|url=https://www.mecum.com/lots/SC0522-503088/1965-brawner-hawk-ford-dean-van-lines-special-indy-car/|title=1965 BRAWNER HAWK FORD 'DEAN VAN LINES SPECIAL' INDY CAR|access-date=23 May 2022}}{{cite web|url=https://www.hotcars.com/1965-brawner-hawk-ford-driven-by-mario-andretti-indy-car/|title=The Ford Race Car Mario Andretti Won Nine Indy Car Wins In|date=22 April 2022 |access-date=23 May 2022}}
