Former world champion Denny Hulme died at the age of 53 from a massive heart attack while taking part in the Bathurst 1000 in Australia.

Sebastian Vettel took a dominant victory in the Japanese Grand Prix at Suzuka, keeping his title hopes alive after leaders Rubens Barrichello and Jenson Button finished well down the order in seventh and eighth. Vettel never looked under threat, keeping a comfortable gap between his Red Bull and the Toyota of Jarno Trulli, who fended off McLaren's Lewis Hamilton for second.
