1923 Mercedes Indianapolis

Paul Daimler’s last design for DMG: The engine of this car was based on the successful 10/40/65 hp racing car. This version was the first to be fitted with an oil cooler and with the crankshaft supported in roller bearings. The engine was screwed down to the chassis, which made the chassis more rigid. The first race it entered was the Indianapolis 500 mile race, USA. Due to a slippery track, Lautenschlager had an accident, and eventually Sailer and Werner came in 8th and 11th, the best results for European drivers and constructors. Driven by Salzer and Merz, the car also participated in several mountain races in Europe.
