Louis and Arthur Chevrolet formed the Chevrolet car company with Billy Durant in 1911. Just a few years later the brothers had a falling out with Durant over engineering issues and left the company.
In 1916 Gaston Chevrolet became a partner with his brothers, Louis and Arthur, in Frontenac Motors. The Fontenac race cars had some initial successes which included Chevrolet’s Indianapolis win, but the race car’s days were numbered. Their four-cylinder engines suffered reliability problems and were increasingly not competitive with the new Duesenberg straight-8s and the soon-to-be Miller engines.
In 1921 Frontenac won its second Indianapolis 500 but this was the high point in the Frontenac history. The company went bankrupt in 1923.
