Super Aguri SA06
The Super Aguri SA06 was the car with which the Super Aguri team competed in the latter part of the Formula One season. It was driven by Takuma Sato, who drove for the team throughout the year, and rookie campatriot Sakon Yamamoto, whose début at the German GP coincided with that of the new car. The car was a refined version of the SA05, which in turn was a development of the Arrows A23 chassis from . It featured revised aerodynamics, suspension and a new quick-shift gearbox, along with a lightened chassis and provided a worthwhile improvement  in performance. A new livery with more red was also used. This culminated with a fine display at the Brazilian GP, where Sato finished 10th out of 16 finishers, and he and Yamamoto set ninth- and seventh-fastest laps of the race respectively. Despite this effort, the team were unclassified in the Constructors' Championship, with no points. The car was followed by the SA07. However, the SA06 would still be used: on January 15, 2007, retired F1 drivers Aguri Suzuki (the team owner), Martin Brundle and Christian Danner all drove the car at Silverstone. Following Super Aguri's financial collapse  and withdrawal from F1 in , an SA06 chassis was sold to a Japanese buyer for £85,600 in an auction held by the team's liquidators.
