BTCC championship leader Colin Turkington has announced his statement of intent by leading a WSR BMW one-two ahead of team mate Rob Collard during Knockhill's opening practice.
The 2009 champion has confirmed the leading FWD runner's pre-Knockhill fears after the eBay Motors driver was the only man to dip under the 52 second bracket with a 51.870 second lap.
Turkington, however, will need all the pace he can get, as the WSR-man carries an eight-place grid penalty following his clash with Matt Neal last time out at Snetterton.
Behind the two BMW 1-Series' was the MG of Jason Plato over five-tenths off Turkington's searing pace.
Plato, in turn, was a tenth quicker than home favourite Gordon Shedden in his Civic Tourer while reigning champion Andrew Jordan was fifth for Pirtek Honda.
Jordan returns to the fray after missing the Snetterton finale due to exhaustion as a result from his high speed FP1 shunt at the Norfolk circuit which left the Pirtek driver sidelined on the Saturday.
Next up was the sister MG of Sam Tordoff in sixth position ahead of Alain Menu's BMR Volkswagen in seventh. Menu had led the initial running before making way for the BMW charge.
Rob Austin was the one and only Audi in the top ten running in eighth while Nick Foster was the third eBay BMW in ninth.
Former triple-champion Matt Neal was tenth for Honda but almost a second off the ultimate pace.
