At the beginning of the 1950s, an aircraft manufacturer and an ingenious designer joined forces to build the first French car with a turbine engine. The SOCÉMA-Grégoire not only looked like it was from the year 2000, it was also supposed to be capable of speeds in excess of 200 km/h. Unfortunately, it was never allowed to show what it could do and disappeared into insignificance shortly after its premiere. This article tells the story of the SOCÉMA-Grégoire and shows it in historical photographs.
