Stefan Bellof (20 November 1957 – 1 September 1985) was a German racing driver. Bellof was the winner of the Drivers' Championship in the 1984 FIA World Endurance Championship, driving for the factory Rothmans Porsche team. His lap record on the Nordschleife configuration at the Nürburgring, set while qualifying for the 1000 km race in 1983, stood for 35 years, when it was beaten by Timo Bernhard in 2018. He also competed with the Tyrrell Formula One team during 1984 and 1985. Bellof was killed in an accident during the 1985 1000 km of Spa, a round of the World Endurance Championship.
Bellof first tested a Formula One car towards the end of 1983, when he joined the top two drivers from that season's British Formula 3 Championship – Ayrton Senna and Martin Brundle – in testing for McLaren at Silverstone, where Bellof damaged the gearbox before Brundle's opportunity behind the wheel. Bellof did move into the championship ahead of the 1984 season, joining Tyrrell Racing Organisation, to partner Brundle in naturally aspirated, Ford-engined machinery, which were giving away in excess of 150 horsepower (110 kW) to their turbo rivals. Bellof failed to finish in his first two races in Brazil and South Africa, before scoring his first two championship points in successive races at Zolder and Imola. A retirement followed at Dijon, before Bellof achieved a podium finish in the rain-shortened Monaco Grand Prix. Despite starting down in 20th and last place, Bellof remained away from the barriers that caught out many of his rivals, and was catching the race-leading pairing of Alain Prost and Senna when the race was curtailed after 31 laps due to inclement weather conditions. At the end of the race, Bellof had been 21 seconds in arrears of Prost and 13.7 behind Senna. Retirements followed in Canada and in Detroit, where Brundle claimed the team's best result of the season with second position as Bellof stuck his Tyrrell in the pit wall.
However, Bellof, Brundle and the team were stripped of all their championship points, after their cars were disqualified from the 1984 season after a dispute over lead ballast in their fuel tanks found after the Detroit Grand Prix. FISA charged the team on four separate counts, but the team appealed for injunctions to allow them to continue competing in the championship. Ultimately, the FIA Court of Appeal rejected their final appeal and kicked the team out of the remainder of the season.
