リカルド・ゾンタ
Panis remained with Toyota for 2004, his tenth season in Formula One. In early October 2004 he announced his intention to retire from racing following the 2004 Japanese Grand Prix; he planned to continue at Toyota as a test driver in 2005 and 2006. Before his retirement, he was the oldest active driver in F1 at the age of 37. 2004 saw him again score only 6 points, before being replaced for Brazil by his Brazilian teammate test driver Ricardo Zonta.
