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. Sakon Yamamoto, who was a second driver in late 2006, went back to being a test driver in 2007. The team suffered a major setback when their car for 2007 failed the FIA crash test, with the rear of the car being destroyed more than is allowed. On 2 March, Super Aguri pushed back the launch of its new car by two days, with the SA07 unveiled less than 48 hours before the first practice session for the Australian Grand Prix. Team's drivers Davidson and Sato shocked many people with getting 10th and 11th place in qualifying for Australian GP. Until this, the best result in qualification set by this team was 17th place (by Takuma Sato). Sato dropped to 12th by the race's end, while Anthony Davidson's race was ruined on the very first lap when Spyker's Adrian Sutil collided with him after a failed passing move. Davidson's car was thrown into the air, severely jarring his back upon landing. He drove through the pain to finish 16th and was taken to hospital following the race. Shortly before the 2007 Australian Grand Prix, the team announced SS United Group Oil & Gas Company as its title sponsor. Also in 2007 Super Aguri signed an official supplier agreement with Speakerbus to supply race intercom. However, SS United Group defaulted on sponsorship payments, forcing the team to cut as many as 30 staff. At the the team scored its first point ever, when Takuma Sato finished in 8th place.
