 As Matra won several races, Ferrari needed to enter in the 1973 24 Hours of Le Mans, with an improved yet still doubtful engine.One car was used as a "hare" which supposed to lure the Matras into driving faster laps than they intended, to test their reliability.Ironically it was only the "hare" Ferrari which survived the 24 hours, finishing a respectable second behind a Matra.
