Sumar Special was the name of cars entered in Indy car racing in 1950s by Chapman S. Root, team owner and president of Associated Coca-Cola. Chapman Root and Don Smith, who were significant participants at Indianapolis during the Golden era, commissioned Frank Kurtis to build cars for them since 1953. Sumar was coined from their wives first names, Susan and Mary. In the 1957 Indianapolis 500 two Sumar Special cars were driven by Pat O’Connor and Marshall Teague. O’Connor qualified his car to pole, while Teague started from 28th position. O’Connor led the race during few first laps, but could not convert his pole to win, and finished eights. Teague ended up sevenths. O’Connor drove the Sumar Spl at Indy next year, and was fatally injured in opening-lap pileup in Turn 3. O’Connor who started fifth, hit Jimmy Reece’s car, sailed fifty feet in the air, landed upside down, and burst into flames. Marshal Teague also lost his life driving Sumar car. In 1959, Teague was driving the Sumar Streamliner at Daytona International Speedway for an attempt at a closed course speed record. During the multiple days of the attempt he actually clocked over 171 mph in the car. Two days later while traveling an estimated 140 mph, the car spun and flipped through turn three and Teague was thrown seat and all from the car. He died from the injuries.
