A downpour in the desert made this a four-day weekend, as MotoGP took the unpredecented step of postponing its Qatar night race until Monday - not that a 22-hour delay could stop Casey Stoner winning at Losail for a third straight year.
The Algarve A1GP races headlined the weekend's four-wheeled action, with Vitantonio Liuzzi starring on his debut, Robert Doornbos and Neel Jani taking the wins, and Ireland losing the points lead to the Swiss following a penalty for Adam Carroll.
Elsewhere, Daniel Ricciardo announced his arrival in British Formula 3 with a double victory at Oulton Park, and Joey Logano put his Sprint Cup struggles aside to win the Nashville NASCAR Nationwide race.
