The Blitzen Benz is a race car built by Benz & Cie in Mannheim, Germany, in 1909. In 1910 an enhanced model broke the world land speed record. It was one of six cars based on the Grand Prix car, but it had an enlarged engine, 21,504 cm3 (1,312.3 in3), 200 hp (149.1 kW) inline-four, and improved aerodynamics. Of the six Blitzen Benzes ever made, only two survive—Mercedes-Benz owns one, while the other belongs to a U.S. collector. At Brooklands on 9 November 1909, land speed racer Victor Hémery of France set a record with an average speed of 202.7 kilometres per hour (126.0 mph) over a kilometre.
