thus preventing his return to an F1 seat until at least the 2007 season. Montagny raced until and including the , and on 8 June 2006 Sakon Yamamoto became Super Aguri's third driver. Montagny and Yamamoto swapped roles for the , with Yamamoto taking over Super Aguri's second car. When the updated car (the SA06) was first raced in the German Grand Prix, it managed to impress, with decent qualifying positions (managing to outperform the Midland F1 Team), although failing to finish the race. The team's improving form culminated with an impressive tenth place at the from Sato, whilst Yamamoto set the seventh-fastest fastest lap, less than a second behind most of the points-finishers. 2007 Reports suggesting that the team would be using the works Honda chassis of 2006 came under intense resistance by rival teams Williams and Spyker, who contested that the practice was against Formula One regulations. The teams cited the fact that the Concorde Agreement mandated a car may not use any parts designed or constructed by another manufacturer of Formula One cars. Super Aguri (as well as Scuderia Toro Rosso and Red Bull) seemed to be in violation about this. The FIA however did not have the authority to act on the Concorde Agreement without the matter already being resolved in court. However, Super Aguri (as well as the Red Bull teams) stated that they were in compliance with the sport's regulations, though the matter was still of great contention. Super Aguri announced on 15 November 2006 that Takuma Sato and Anthony Davidson (previously Honda third and test driver) would be driving for the team in 2007. Super Aguri also confirmed, on 15 December, that Giedo van der Garde would be their third driver in the 2007 season. However, the Dutchman left for Spyker F1 before the season began.

Team's drivers Davidson and Sato shocked many people with getting 10th and 11th place in qualifying
