The 2010 Drivers' Championship race is the closest for three decades and Hills, who have doubled their F1 turnover compared to twelve months ago, expect six-figure sums to be wagered on the final two races of the season.

Hill's spokesman Joe Crilly told Oddspreview: "This year's Drivers' Championship has had more twists and turns than the track at Monaco and there could yet be a few more in Brazil."

Fernando Alonso, who is the current 8/13 favourite to win the title, is 7/1 to win at Interlagos.
