Gunnar Nilsson raced for 2 almost full seasons in Formula One, in 1976–77 – qualifying his Lotus for every Grand Prix he entered. His short career was very up-and-down, with 17 retirements along with 4 podiums, including a win in the 1977 Belgian Grand Prix. He retired from his last 7 straight Grands Prix and was beginning to show the signs of the testicular cancer that would eventually kill him at the time.
