Motor racing-BMW and Williams summoned to stewards in Brazil
SAO PAULO, Oct 21 (Reuters) - A question mark hung over Kimi Raikkonen's Formula One title on Sunday after Brazilian Grand Prix stewards summoned representatives of BMW Sauber and Williams for alleged technical irregularities.
A BMW spokeswoman said the investigation concerned fuel temperatures.
Williams' Nico Rosberg finished fourth in the race with BMW's Sauber's Robert Kubica and Nick Heidfeld fifth and sixth.
Should they be disqualified, McLaren's Lewis Hamilton would be promoted to fourth place - handing the 22-year-old British rookie the title.
Ferrari's Raikkonen beat Hamilton and his Spanish team mate Fernando Alonso by one point after winning Sunday's race at Interlagos. Alonso was third and Hamilton seventh.
