The 1986 championship culminated in a battle between Williams drivers Nigel Mansell and Nelson Piquet and McLaren driver Alain Prost at the final race, the Australian Grand Prix. Mansell's tyre exploded and Piquet was brought in for a precautionary pit stop for tyres as a result, leaving Prost to win the race and his second consecutive Drivers' Championship. Mansell, Piquet and Prost, along with Lotus' Ayrton Senna, dominated throughout the season and formed what was dubbed as the "Gang of Four".
