Kazuki Nakajima
Williams signed Rubens Barrichello and Nico Hülkenberg for 2010, leaving Nakajima without a seat. Stefan GP announced on 19 February 2010 that Nakajima was one of the team's drivers. Strefan GP was built from the remains of the Toyota F1 team. Toyota had withdrawn from F1 in late 2009. Stefan GP did not have an entry to the 2010 Formula One season. The FIA ruled that Stefan GP could not be entered for the season at such a late stage. That left Nakajima with no ride in Formula One for 2010.
