A Grand Chelem or Grand Slam is scored in motor racing if a driver scores pole position in qualifying, the fastest lap in the race and then winning while leading every lap of the race in the same weekend. This significant feat is equivalent to a perfect game in baseball, or a 300-game in ten-pin bowling.
To date, only 24 drivers have secured a Grand Chelem. There have only been 61 in total.
Juan Manuel Fangio took the first Grand Chelem in a Formula One World Championship race at the 1950 Monaco Grand Prix. It was only the second World Championship race. Jim Clark obtained the most Grand Chelems, with eight, amazingly all achieved in a 32-race period which spanned just over three years. The most recent was at the 2017 British Grand Prix, where Lewis Hamilton achieved the feat.
