Despite being firmly involved in his successful touring cars career and 33 years old, Tarquini was signed up by Tyrrell for the 1995 season as their test driver thanks to the presence of Fondmetal as a sponsor. He replaced Ukyo Katayama for the European round as the Japanese driver was injured from his start line accident in the previous race. Out of practice with single seaters (having done very little actual testing due to the team's financial constraints) he finished 14th, six laps down on winner Michael Schumacher. It was his final Grand Prix.
