1933 Willys Drag Racer

Racing car

When machinist George Montgomery started racing in 1953, all drag racers were amateurs with "real jobs" supporting their hobby. This car helped change all that. Montgomery bought an old Willys in 1958 and built a dragster so successful that promoters started paying him to run at drag strips nationwide. In 1966, Montgomery became one of drag racing's first full-time professional drivers.

Photographic print

In 1937, the 25th running of the Indianapolis 500 saw 33 entrants and one of the closest margins of victory: 2.16 seconds for Wilbur Shaw. Note that these high-powered race cars still required a two-man team of a driver and a riding mechanic to keep the cars running at top speed.

1984 March 84C-Cosworth Race Car

Racing car

Tom Sneva set the fastest qualifying lap at the 1984 Indianapolis 500 with this car, but a broken rear suspension forced him out early during the actual race. The car's front and rear wings and underbody ground effects represent the aerodynamic advances that increasingly shaped race cars in the 1970s -- and continue to do so today.
