Indianapolis (United States): Narain Karthikeyan finished fourth in the United States Grand Prix, which was won by seven-time world champion Michael Schumacher of Germany.

Schumacher's Ferrari team-mate Rubens Barrichello of Brazil came second ahead of Portugal's Tiago Monteiro of Jordan.

The competition became a six-car race when seven teams pulled out over concerns over the safety of their Michelin tyres.
