1978

Gunnar Nilsson, winner of the 1977 Belgian Grand Prix, tragically passed away from cancer at just 29 years old. “His rare talent had taken him swiftly to the top as No. 2 to Mario Andretti,” wrote The Times, “[and] he was perhaps the most naturally gifted of the new generation of Grand Prix drivers.” Diagnosed at the end of 1977, Nilsson had signed with Arrows as their lead driver for the 1978 season, but his illness progressed rapidly, forcing him to step down before the first race. In his remaining months, Nilsson focused on establishing the Gunnar Nilsson Cancer Treatment Campaign, in partnership with Charing Cross Hospital, working tirelessly and refusing painkillers to remain active in his cause. His death came just five weeks after the loss of his close friend and rival, Ronnie Peterson.

1991

After the dramatic finale of the previous season, Ayrton Senna once again found himself leading the championship heading into the 1991 Japanese Grand Prix. Nigel Mansell, needing a win to keep his title hopes alive, started alongside Senna on the front row. However, it was Senna’s McLaren teammate, Gerhard Berger, who took the lead into the first corner. Mansell, pushing aggressively to overtake Senna, spun out on lap ten due to brake failure on his Williams, handing the championship to Senna. With Berger struggling with tyre issues later in the race, Senna took the lead but then displayed one of the most compassionate moments of his career, allowing his friend Berger to pass and take victory at the final corner. Reflecting on his crash, Mansell said, “The brake pedal went soft and I couldn’t slow down. It’s a pity it finished this way, but I can’t be too unhappy. We’ve had a great championship, and Williams gave me the shot they promised.” Mansell’s teammate Riccardo Patrese was third.

Sadly, this would be Senna’s last-ever Championship, his third, after which he suffered a tragic death at the 1994 San Marino Grand Prix while driving for Williams.
