#1 Jim Clark (8 Grand Slams)
At the number one spot is British Motorsport legend Jim Clark. James Clark, junior, was born on March 4, 1936, and lived in Scotland's Berwickshire.
He was widely regarded as one of the quickest drivers in the history of the sport. Paired with that Lotus some race weekends he just looked in a world of his own. The Scot won his first grand slam at the British Grand Prix in Aintree in 1962 with the last arriving at the Nurburgring at the German Grand Prix in 1965.
When he died in 1968 he had won 25 Grand Prix from 72 starts (73 entries). At 32 years old when he died it was so tragic to lose a driver that could have achieved much more. The sport was so much more dangerous back then but Clark did win two F1 championships in his career, 1963 and 1965.
He was an inspiration for many drivers that have followed in his footsteps and many more drivers to come. This record of grand slams is also a great achievement and one that will still see his name at the top for a few more years to come.
Here is the list of races where he achieved his grand slams:
1962 British Grand Prix, 1963 Dutch Grand Prix, 1963 French Grand Prix, 1963 Mexican Grand Prix, 1964 British Grand Prix, 1965 South African Grand Prix, 1965 French Grand Prix, 1965 German Grand Prix
