Despite coming up half a point short of clinching the Formula One constructors' title in its maiden season, Brawn GP may yet leave Suzuka with the silverware.
Seventh and eighth places for Rubens Barrichello and Jenson Button weren't quite enough to offset Sebastian Vettel's ten-point haul for victory in the best of the Red Bull Racing entries, but post-race complaints about Nico Rosberg's antics behind the late-race safety car have forced the FIA to leave the Japanese Grand Prix results as provisional pending an investigation.
The Williams driver is accused of exceeding the target lap time set for the caution period as he hurried back to the pits to make his second stop, and actually gained ground on both Brawns and Nick Heidfeld. If found guilty, he would attract a 25-second post-race penalty that would be enough - thanks to the timing of the safety car - to drop him to the tail of those on the lead lap, in 15th position.
More importantly, however, it would promote Barrichello and Button to sixth and seventh, giving Brawn the additional half point - and more - that it needs to ensure Red Bull cannot threaten its position in the final two races, in Brazil and Abu Dhabi, and hand both drivers an extra point apiece in their battle with Vettel for the drivers' crown.
