The 1986 season-opening Brazilian Grand Prix lasted less than one lap for Nigel Mansell following a wheel-touching incident with Ayrton Senna.
At the Jacarepagua circuit in Rio de Janeiro, Senna had produced a stunning qualifying lap in his Lotus, beating his fellow Brazilian in Renault's Nelson Piquet by three-quarters of a second, with Mansell lining up third in his Renault.
The Briton, however, produced a storming start off the line to surge past Piquet, before then lining up Senna later in the lap. The latter, though, had the racing line on the long run down to turn six, Sul.
As Senna turned in, the duo brushed wheels, sending Mansell sliding off the track and into a barrier, forcing his retirement.
You could argue it proved costly for Mansell. In a season in which only the best 11 results counted, Mansell missed out on the title by two points to McLaren's Alain Prost.
