SEAT looks set to return to form in this weekend's World Touring Car round at Valencia after dominating Saturday's first practice session.
The Spanish manufacturer's Leon TDi was well off the pace in the last event at Pau, but has been granted an increase in its turbo boost pressure to 2.7 from this weekend and started strongly, filling the first three places.
Reigning champion Yvan Muller set the quickest time of the half-hour session, quarter of a second clear of SEAT Sport team-mate Rickard Rydell and half a second ahead of fellow stable-mate Gabriele Tarquini.
Tom Coronel was fourth quickest in his petrol-powered SUNRED Engineering Leon, with Nicola Larini in the first of the Chevrolets and Alex Zanardi in the fastest BMW six tenths off Muller's pace in fifth and sixth.
The fully laden factory BMW's (Zanardi's weight is calculated separately from his team-mates' due to his sequential gearbox) lined up from ninth to 11th places, one second shy of Muller.
