Unusual Racing Cars

Golden Submarine
An expensive custom-made race car built in 1917 by Harry
Miller that would help change the shape of things to come in
American auto racing. The Golden Submarine carried an
unimaginable ticket price of $15,000 at its completion. Its
gold color was the result of a combination of lacquer and
bronze dust. The Golden Submarine never won the Indy 500,
though it ran in 1919, pulling out with engine trouble; but
its designs foreshadowed the future of American racing.
Miller's design would dominate Indy for over 30 years
Pat Clancy Special
This car was raced at the Indianapolis 500 in 1948, sporting
no less than six wheels. The four wheels at the back were
driven by two axles connected by a universal joint, making
the Pat Clancy Special a four-wheel drive car. Powered by a
Meyer-Drake engine and driven by Billy DeVore the car was
still running at the end and was classified 12th. It remains
the only six-wheeled car to complete the Indianapolis 500.
The car was converted to a conventional four-wheeler and won
races in 1949 and 1950 with Jimmy Davies driving.
The "Green Monster"
A land-speed racer built using a military surplus J79 jet
aircraft engine with an afterburner. On October 5, 1964 the
Green Monster jet powered to 434.022--a new land-speed
record. In 1965, a revamped Green Monster returned and
shattered the record again at 576.553mph across the one-mile
course. (driven by Art Arfons).
