At the Indianapolis Motor Speedway, the 1940s were a time of technical innocence and exploration. Race car builders experimented with all manner of different ideas, including mid-engine layouts, front-wheel drive, and even twin engines. One unique racer that perennially captures the imaginations of Indy 500 fans is the six-wheeled Pat Clancy Special, which appeared at Indy in 1948 and 1949.

Unlike many of the wackier experiments at Indy, the Clancy Special was nominally competitive, more or less, and actually made the race in its first appearance in 1948. Veteran Billy DeVore qualified 21st and finished 12th in the six-wheeler, 10 laps behind winner Mauri Rose in the front-drive Blue Crown Spark Plug Special.
