Sunday 7th May 1939
The Mercedes-Benz W165 is a racing car designed by Mercedes-Benz to meet voiturette racing regulations, won its only race, the 1939 Tripoli Grand Prix, driven to a 1-2 victory by Hermann Lang and teammate Rudolf Caracciola. This car was remarkably designed and built in 6 months, which was the time that the rules were changed by the Italian organizers. The car had a 1.5L supercharged V8 engine. Following an invitation by Indianapolis Motor Speedway owner Tony Hulman, Caracciola entered a W165 in the 1946 Indianapolis 500. However, Swiss customs refused to allow the car out of their country, preventing Caracciola from competing.
