Darren Turner made the most of a drying track to post the fastest time in the opening free practice session for the HiQ MSA British Touring Car Championship at Knockhill.

The SEAT Sport UK driver posted a time of 54.204secs on his final lap of the 40 minute session to edge out team-mate Jason Plato by a tenth of a second, with the diesel-powered pair comfortably clear of third-placed Tom Onslow-Cole. The VX Racing man ended the session over eight-tenths of a second behind Turner, despite Turner taking a trip through the gravel while chasing his quickest time.

Behind Onslow-Cole, Colin Turkington took fourth place for Team RAC, while Fabrizio Giovanardi and Matt Neal rounded out the top six - putting all three Vectras near the head of the field.

Mike Jordan was seventh and leading BTC-spec runner, with Mat Jackson, home hero Gordon Shedden and Rob Collard completing the top ten. Adam Jones just missed out on the top ten and suffered a trip into the gravel at the hairpin.

The second home driver, Micky Doyle, produced an impressive performance to set the 15th quickest time.
