Sauber uses first curfew exception

Sauber has used up one of its four curfew exceptions at the Japanese Grand Prix after staff stayed at the track late on Friday to work on the latest car updates. The Swiss team introduced a big development upgrade to its car for the Suzuka event as it bids to hold on to seventh place in the constructors' championship.
