Despite some speculation that GP2 champion Nico Rosberg would be given an opportunity in the last two races of the season, Pizzonia completed the season for Williams. He retired from the Japanese Grand Prix early after spinning off, and retired from (but was classified as a finisher in) the Chinese Grand Prix after a puncture. Having been replaced by Nico Rosberg for 2006, Pizzonia's Formula One career was over.
