History of diesel engine cars in Indy
[sc:text-divider text-divider-title=”Story continues below gallery” ]
It turns out that the story of diesel engine cars at Indianapolis actually starts with the first Indianapolis 500 in 1911.
Clessie Cummins, who started Cummins Engine Co., crewed for Ray Harroun, who won the first Indianapolis 500 in 1911. In 1919, he started Cummins in Columbus. Over the years, Cummins entered cars in the Indianapolis 500 in 1931, 1934 and 1950, in addition to the 1952 Indianapolis 500.
In 1952, Cummins made a profoundly serious attempt to win the Indianapolis 500. At that time, the rules allowed diesel engines to be 6.6 liters (400 cubic inches) in size compared to 4.5 liters for normally aspirated engines and 3.0 liters for supercharged engines. As a result, Cummins prepared a 400-cubic-inch 6-cylinder turbocharged diesel engine that produced 380 horsepower.
Cummins also worked closely with Kurtis Kraft to produce a sleek design for the Cummins Diesel Special. To that time, engines in race cars at Indianapolis had been in an upright position; however, with an engine that was much bigger than the other cars, this would result in a noticeably big car.
To overcome some of these size problems, the motor featured an aluminum block and head with a magnesium crank case. The engine was also laid 5 degrees off flat, which provided three advantages: Reduced center of gravity, reduced the frontal area and offset engine provided more weight on the left (inside) wheels.
The design of the Cummins Diesel Special was definitely longer and lower than the other cars in the field, but it was heavier due to the larger engine.
Cummins hired Freddie Agabashian to drive the Cummins Diesel Special. After the car was tested the first time, everyone who was involved knew it was an extremely fast car, so the Cummins team became very secretive. They said nothing.
Agabashian held back for much of the month of May during Indianapolis 500 preparations until pole day, either by lifting off on the back straight one lap or by cruising through a turn on another lap. He never completed a whole lap under full power so as not to draw attention to the car’s capability and risk having the rules changed.
Then at 5:45 p.m. on pole day, 15 minutes before the end of qualifying, Agabashian and the heavy 3,100-pound Cummins Diesel Special, fitted with a fresh engine, won the pole position for the Indianapolis 500 by setting an individual lap record of 139 mph and a record four-lap average of 138 mph.
This qualifying speed was more than 1 mph faster than the runner-up. During Indianapolis’ remaining qualifying days that year, other cars went faster, but the Cummins Diesel was on the pole.
The race did not go as well for the Cummins Diesel Special. The turbocharger inlet was clogged with rubber and other debris. The car had to retire after 70 laps, or 180 miles, as the clogging became too bad. The car is listed as finishing 27th.
Soon after, the rules were changed by taking away the use of large diesel engines. A diesel engine has never powered a race car in the Indianapolis 500 since that spectacular year of 1952 when the Cummins Diesel Special won the pole.
Agabashian was respected as a test driver, he was nicknamed “Doc” for his uncanny ability to diagnose what was wrong with a sick car. A regular in the AAA National Championship (now IndyCar) for two seasons, he earned a comfortable living racing midgets instead.
The eldest son of Armenian immigrants, Agabashian started racing those small cars during the mid-1930s and won the 1937 Northern California Racing Association title. He was the class of the field in BCRA midgets after World War II, winning the 1946 championship for Jack London and repeating that success the next two years, having switched to George Bignotti’s stable.
That prompted Agabashian to make his IndyCar debut in the 1947 Indianapolis 500 when he finished ninth with a Ross Page Kurtis-Duray. He scored his only IndyCar victory in what was only his fourth start in the National Championship.
His J.C. Agajanian Kurtis-Offenhauser started from pole position on Sacramento’s California State Fair dirt oval in October 1949, and Agabashian led all but two laps that day to win at an average speed of 84.486 mph.
He was a full-time IndyCar driver in 1950, qualifying the Wynn’s Friction Proofing Kurtis-Offy on the front row at Indy and scoring two top-five finishes.
He qualified Andy Granatelli’s Elgin Piston Pin Kurtis KK500B-Offy on the front row again in 1953 and finished fourth in the hottest race in history with Paul Russo driving as his relief from Lap 105. Sixth at the finish in 1954, fourth on the grid in 1955 and 1957, Agabashian retired from the sport after failing to qualify for the 1958 Indy 500.
He then joined the Champion Spark Plug company and worked as an analyst on radio broadcasts of the Indianapolis 500 between 1959 and 1965 and again from 1973 to 1977. He is a member of both the National Midget Hall of Fame and the Indianapolis Motor Speedway Hall of Fame.
