The 1991 Spanish Grand Prix was the first to be held at the newly-completed Circuit de Catalunya, a race best remembered for a thrilling wheel-to-wheel battle between Ayrton Senna and Nigel Mansell.
It was a race Mansell had to win to keep his slim championship hopes alive, and as Mansell came upon Senna on a drying track, the pair raced down the long start/finish straight neck-a-neck, their wheels just inches apart. It was thrilling stuff!
