The 640 was plagued with reliability issues, and eventually it turned out that a fault alternator belt was the cause. The following 641 should have been Barnard’s masterpiece, but was in fact just a re-heated 640, with the designer leaving just as Prost arrived.
“Had I known [Prost was coming], perhaps I’d have stayed,” he told Motor Sport.
Despite this, the Frenchman had one of his best years in 1990, almost willing the Ferrari to five wins in a fierce battle with Senna until the Brazilian quite literally took Prost out of championship contention at the first corner of the penultimate round in Suzuka.
It’s a cliché that when things aren’t going well, Ferrari always finds a scapegoat. In 1991, that person was Prost.
Neither he nor new signing Jean Alesi scored any wins all season in the lacklustre 643 car, and after the second-to-last race in Japan, Prost likened his to a truck. He was promptly fired.
Ivan Capelli – 1992
Following Prost’s removal, rising star Ivan Capelli was lined up as the Scuderia’s next victim in 1992.
The Milanese ace had been a key part of the Leyton House team, nearly winning the 1990 French GP in a car designed by Adrian Newey.
When Leyton House went under at the end of 1991, Ferrari moved to bring in Capelli to partner Jean Alesi.
