Brawner Hawk

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 255 cid, and later turbocharged 159-162 cid, 700 hp, 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 1400 lb, giving it an incredible power-to-weight ratio.
