History 

Cummins is named for inventor Clessie Cummins, who was instrumental in the company's foundation. From 1919, when he began to enhance the design of existing diesel engines, he was financially backed by William Irwin. Cummins manufactured some Duesenberg racing vehicles for the 500 miles of Indianapolis between 1929 and 1934 to demonstrate the benefits of the diesel engine.

In 1931 a Duesenberg Cummins in Daytona Beach set the world record for diesel vehicles with 100.75 mph (162.141 km / h).  1934, "Stubby" Stubblefield qualified in a Duesenberg race car just with the second worst time for Indianapolis. His car had a six-cylinder Diesel two-stroke engine from Cummins. It went through the entire 500 miles, eventually finishing in 12th place. Cummins diesels were occasionally installed in Indy racing cars until 1952. 

In 1930, Clessie Cummins had driven from Indianapolis to New York with a car converted to Cummins Diesel. For this distance of 792 miles (1274 km) he consumed fuel for just 1.38 US dollars. In 1935, he exhibited at the Motor Show in New York City Auburn passenger cars with Cummins diesel engine. The vehicle did not go into production.
