Andretti Autosport announced on Friday that the former Formula One driver would be joining them in their four car project.
“I think joining the team will be a new and positive opportunity for Takuma,” Andretti said. “He’s not yet had the chance to be part of a larger team where the drivers collaborate; our four drivers and team of engineers working together has bred success for us in the past and has helped many drivers develop on track.
"Takuma has strong racing experience and we are looking forward to providing a team atmosphere where he can continue to grow, develop and be successful.”
Sato expressed that he is excited to join the team and admits that the team's relationship with Honda was a vital part in his decision to join.
"I am extremely excited that we were able to work out a deal with Michael and Andretti Autosport,” Sato said. “With Honda an integral part of Andretti Autosport, it seemed like a great fit. The team has proven year after year that they are ultracompetitive on all types of circuits.
"Particularly the speed that team has shown in recent years at the Indy 500 were just incredible. I am also very impressed on how aggressively they have addressed their needs for 2017, and am really looking forward to working with my new environment and can’t wait to get started.”
Sato will line-up alongside Marco Andretti, Ryan Hunter-Reay and Alexander Rossi.
