Toyota TF101

The Toyota TF101, originally known as the Toyota AM01, was a Formula One car used solely for testing during the 2001 season, in preparation for the team's full-scale assault on the series in 2002. It was designed by Toyota F1's chief of chassis Jean-Claude Martens and driven by Mika Salo and Allan McNish. The car was designed and built from the ground up by the staff at Toyota Motorsports GmbH in Cologne, Germany, over nineteen months, and the test team accumulated 3,000 laps and 22,967 km at eleven Formula One circuits and at the Paul Ricard test facility in southern France. Austrian designer Gustav Brunner replaced the initial designer André de Cortanze during development and oversaw the work that became the TF102. It was the first Formula One car to run on Esso fuel since the 1960s.
