Messerschmitt Bf 109 was called the Me 109R, suggesting it was just another variant of the standard fighter, but in fact it was a racing aircraft having little in common with the Bf 109. It was powered by the DB 601ARJ, producing 1,156 kW (1,550 hp), but capable of reaching 1,715 kW (2,300 hp). This world record for a piston-engined aircraft was to stand until 1969, when Darryl Greenamyer's modified Grumman F8F Bearcat, "Conquest I", broke it with a 777 km/h (483 mph) record speed. When the Bf 109 was designed in 1934, by a team led by Willy Messerschmitt and Robert Lusser,
Willy Messerschmitt Robert Lusser, Messerschmitt designed the flagship product of the relaunched company, a low-wing four seater monoplane called the Messerschmitt M37, but better known by its later RLM designation of Bf 108. The following year, Messerschmitt would incorporate many advanced design features of this aircraft into the Bf 109 fighter. When in 1936, the Messerschmitt Bf 109 won the RLM's single-seat fighter contest to become one of the main Luftwaffe aircraft types, Messerschmitt and his factory took an important role in the RLM's armament plans, increasing in significance even further when Messerschmitt's Bf 110 also won the multi-purpose fighter contest.
