9. Sauber C9
Before the Mercedes C11 and the introduction of the manufacturer name, there was the Sauber C9. Powered by a Mercedes twin-blown V8, it as introduced in 1987 and suffered two years of reliability issues before everything came together. In 1989 at Le Mans, the C9 finished first and second. During qualifying, the C9 hit 400kph on the Mulsanne straight – a speed so immense that everyone got freaked out, and chicanes were installed on the track for the following year to keep the velocity down.
