Lorraine 5P
      
The Lorraine 5P, also called the Lorraine 100CV, Lorraine 110CV and Lorraine 120CV, was a family of five-cylinder air-cooled radial engines designed and built in France by Lorraine-Dietrich during the 1920s and 1930s. Nominal engine powers were given as 100–110–120 hp (75–82–89 kW) at 1250 / 1400 / 1350 rpm (maximum continuous power), with maximum outputs of 108–125–150 hp (81–93–112 kW)  at 1350 / 1650 / 1700 rpm.
