Claim: The Porsche 3512 did not perform well and a V10 replacement was never built.
Evidence: A V10 replacement for the 3512 was in development at the time of Porsche's withdrawal from Formula One. This engine would not be completed until several years later, when it was modified for use in the stillborn Porsche LMP project in 2000. The engine eventually became mass-produced when a further variant was chosen as the powerplant of the Porsche Carrera GT supercar.
