The Italian Grand Prix saw Brawn's first one-two since Monaco, a disaster for Red Bull and a crucial win for Rubens Barrichello - but until the red lights went out, the paddock had been dominated by talk of the upcoming hearing over the Renault race-fixing allegations.
Leaked evidence prompted more and more revelations as the weekend progressed, and with Renault beginning criminal proceedings against the Piquet family, the saga looks set to run on beyond next week's FIA meeting.
The scandal overshadowed Giancarlo Fisichella's muted Ferrari debut and Tonio Liuzzi's superb return with Force India, and also the news conference in which Ferrari confirmed its long-anticipated Santander deal, but not its 2010 drivers.
While the Italian GP distilled the Formula title battle into a two-horse race, elsewhere a host of championships were sealed. A podium finish in a dramatic AUTOSPORT 1000km was enough to give Aston Martin the Le Mans Series title in its first season at LMP1 level, and a cautious run to third at Monza was sufficient to tie up the GP2 crown for Nico Hulkenberg as well. Luiz Razia took a surprise maiden win in that race, while Giedo van der Garde had conquered Saturday's wet and wild event.
British Formula 3's visit to the Algarve was dominated by Euro Series visitor Jules Bianchi, but Daniel Ricciardo left the circuit happiest of all as he put the championship beyond the struggling Walter Grubmuller's reach.
The NASCAR Sprint Cup title will not be settled for a while yet, but Richmond decided the identity of the 12 drivers in the Chase. Denny Hamlin underlined his presence in the run-off with a victory, as Red Bull's Brian Vickers beat big name rivals Matt Kenseth and Kyle Busch to the 12th and final spot.
