In his first race, the Australian Grand Prix, Karthikeyan qualified in 12th position. After a poor start which saw him drop to 18th place by the end of the first lap, he finished in 15th, two laps behind winner Giancarlo Fisichella. He achieved his first points in the 2005 United States Grand Prix where all but three teams pulled out due to an argument over tyre safety. He finished fourth, finishing ahead of the two Minardi drivers but behind teammate Monteiro. Apart from the USGP, his highest finish was 11th place. In the 2005 Japanese Grand Prix free practice, he was fastest for a long period and eventually qualified 11th. At the 2005 Chinese Grand Prix he qualified in 15th place. In an unlucky end to his 2005 season, Karthikeyan crashed his Jordan into a wall at the Chinese race, but was unhurt and able to provide an interview afterwards.
