Koch was among Carel’s best friends, but as drivers they only teamed up once – in the 1963 Le Mans 24 Hrs. Sharing a works Porsche 356B, chassis 122-992, they qualified 28th but did not finish the race.
Koch’s sportscar career continued into the sixties, becoming one of Porsche’s main privateers and providing excellent backup to the works team. In 1970 Koch became one of Porsche’s 908 racers, sharing with Gérard Larrousse and Hans-Dieter Dechent.
The 356B Carel and Gerhard shared in the 1963 Le Mans 24 Hrs.
