Well this may come as a suprise but :
The BMW Sauber and Williams teams have escaped penalty after being investigated by Brazilian Grand Prix stewards over fuel irregularities on their cars at the end of Sunday’s Interlagos race.
Under Formula One racing’s technical regulations fuel temperatures are not allowed to fall more than 10 degrees Celsius below ambient air temperature at any time. According to FIA data, Williams and BMW Sauber exceeded this range during the race, but after lengthy deliberations stewards chose not to impose sanctions.
However, McLaren are expected to appeal the stewards' decision, which if overturned could have serious implications for the 2007 drivers' championship.
Nico Rosberg finished fourth for Williams, with Robert Kubica and Nick Heidfeld fifth and sixth respectively for BMW Sauber. If they were to be disqualified, Lewis Hamilton would move up to from seventh to fourth, giving him enough points to beat Kimi Raikkonen to the title.
