The 1st Finnish driver to enter the formula1 racing scene was Leo Kinnunen. Kinnunen had a short stint in F1 which included just 6 races (1 start and 5 DNQ's) and had no success in those. He raced for the team AAW Racing Team and used the Surtees TS16 car with the Cosworth V8 engine in it. The main reasons due to which Kinnunn couldn't succeed in F1 were that his car was underpowered than the other cars and also the team was not allowed to get the top quality tyres from the manufacturers.
And at that point of time tyres played an immense role in the result of races in F1. During these 6 races the team faced technical difficulties in almost every race. And then due to lack of funding the team had to retire from F1 and thus also ending Leo Kinnunen's carreer in F1. In all Kinnunen played a role of historic importance by being the last driver to wear the open-face helmets in F1.
Next was Mikko Kozarowitzky in 1977. He had a "blink and you will miss" stint in F1 as he just raced a total of 2 races for RAM Racing Team with no successes. Unfortunately he broke his hand while trying to avoid an accident during practice session after which his racing team wanted him to try qualifying in the spare car with broken hand, which lead to spats between him and the team. Eventually he quit the team and retired from F1.
Then came Keijo Erik Rosberg in 1978, popularly known as Keke Rosberg. He became the 1st Finnish driver to win the Formula 1 championship in 1982. Keke debuted in 1978 with the Theodore team and
