SEAT enjoyed a strong start to the race weekend in Brazil after locking out the first five slots in the opening free practice session for the World Touring Car Championship season-opener at Curitiba.

Yvan Muller posted the quickest time of 1min 24.808secs mid-way through the session to lead the way with defending champion followed on the time-sheets by Rickard Rydell, Tiago Monteiro, Jordi Gene and Gabriele Tarquini.

It was left to home hero Augusto Farfus to lead the way for BMW with the sixth quickest time ahead of Jorg Muller, Sergio Hernandez and leading independent runner Felix Porteiro. Nicola Larini's Chevrolet Cruze completed the top ten.

The session wasn't without problems, with Andy Priaulx managing just laps before suffering brake failure on his BMW and Kirill Ladygin and Alex Zanardi both going off at the final corner.
