Ken Tyrrell
When Ken Tyrrell, the team's owner, became disenchanted with the poor performance of the March chassis during the season, he decided he would design and build his own car. He employed Derek Gardner to design it in secret at his own house. The project, codenamed "SP", which meant "Special Project", cost Tyrrell over £22,000 of his own money. The resulting car named Tyrrell 001 made its debut at Oulton Park in a non-championship race.
