In the final race of the 2008 season, the Brazilian Grand Prix, Glock was seventh with a few laps to go when it started to rain. Glock remained on the track with dry-weather tyres, while most of the other drivers, including Lewis Hamilton, opted to pit for wet tyres. The decision to stay out moved Glock up the order, ahead of Hamilton on track. Starting the final lap, Glock was fourth but was struggling on his dry-weather tyres as the rain intensified. He was passed by Toro Rosso's Sebastian Vettel and McLaren's Lewis Hamilton in the final corners. Hamilton regained fifth place to win the 2008 Drivers' Championship. Glock finished the race in sixth and the championship in tenth position, with 25 points, behind teammate Jarno Trulli.
