McLaren's later cars abandoned Mallite in favour of conventional aluminium construction; the Ford and Serenissima engine also saw no further action. For 1967 BRM engines powered the M4B and M5A but it was not until the Cosworth DFV became available in 1968 that McLaren scored their first Formula One wins with the M7A. Herd stayed on designing all of these cars until he left for Cosworth in 1967. McLaren have since become one of the most successful teams in Formula One.
