Lesson: Work, Energy and Power in Racing

Hale Barber and Clarence Warnock established the Barber-Warnock Ford dealership in Indianapolis in 1917 and were active supporters of the Indianapolis 500 race on a 2.5-mile oval track originally paved with brick and one of the most popular and well-known races in the country. In the mid-1920s, Barber-Warnock moved from fans and supporters to participants by sponsoring specially built Model Ts. In 1924, Barber-Warnock entered three "specials" built by the Chevrolet brothers -- Louis, Gaston, and Arthur -- under the Frontenac name. Although fairly powerful and fast, the "Fronty Fords" were no match for the rest of the field, finishing a disappointing 14th, 16th, and 17th.

Bill Elliott set NASCAR's all-time speed record with this car when he qualified for the 1987 Winston 500 at Talladega at 212.809 miles per hour. By the 1980s, "stock cars" only looked stock. Underneath this Thunderbird sheet metal is a purpose-built steel tube frame, racing suspension and brakes, and a racing engine that no Ford dealer ever sold.
