The Marion automobile brand, produced in the United States from 1904 to 1915, was known for its well-constructed, performance-oriented touring cars and roadsters. Manufactured by the Marion Motor Car Company of Indianapolis, Indiana, the marque offered vehicles ranging from modestly powered runabouts to larger, more refined four-cylinder models featuring shaft drive and advanced engineering for the period. Marion automobiles earned a reputation for durability and responsiveness, competing successfully in early endurance runs and reliability trials. Though the company ceased production in 1915, Marion remains a recognized name among veteran and brass-era American automobiles.
