Out of Formula One in 1963, Phil Hill predicted a rough future for the Ferrari team. He said there was too much competition between Mairesse and Surtees. Specifically, he commented "they will harry each other so much that they will force each other to make mistakes". Mairesse's car crashed during the 1963 German Grand Prix. The Ferrari turned over multiple times after swerving off the track. He was rushed to the hospital with a broken arm. His teammate, Surtees, won the race, with Jim Clark second in a Lotus.
