Toyota did not have a great year in 2007; the car struggled from its first tests and never really got off the back foot through the season, despite a strong finish to 2006.
As the leader of the team's chassis department, Frenchman Pascal Vasselon has overseen the cars' design and development through the season, and is uniquely positioned to comment on the problems that were faced by the team.
Vasselon studied aerodynamics at the Sup D'Aero before moving to Renault's road car division, and later, Michelin's F1 operation. He has now been at Toyota for over two full seasons, taking the team forward from its post-Gascoyne era.
