Ash Sutton finished the first British Touring Car Championship practice session at Thruxton with the top time, going quickest in the closing minutes after rain had affected the running.
Thruxton specialist Josh Cook had been on top of the times for much of the first half of the session, eventually putting in his best lap of 1 minute 17.165 seconds after 17 minutes.
NAPA Racing UK’s Daniel Rowbottom then went fastest with a 1:16.921, which stood for over ten minutes as rain showers continued to affect the running.
Six minutes from the end WSR’s Charles Rainford took over at the top with a 1:16.438, but the BMW driver then suffered a puncture in the final minutes of the session.
But it was NAPA’s Sutton who was the only driver to dip into the 1 minutes 15s, his lap of 1:15.677 after switching to dry tyres putting him over half a second clear of WSR’s Aiden Moffat in second.
Reigning champion Jake Hill was third, just under seven tenths off the pace in his Laser Tools Racing BMW, ahead of Restart Racing’s Daniel Lloyd in fourth as the best Hyundai driver and also the top Independent driver.
Adam Morgan was the best of the Team Vertu quartet in fifth, a mere two thousandths ahead of Rainford in sixth.
NAPA’s Dan Cammish was seventh, ahead of the leading Toyota of Gordon Shedden in eighth.
The top ten was completed by NAPA’s Rowbottom and Team Vertu’s Senna Proctor, returning to the BTCC fold after several seasons away.
Behind 11th-placed Tom Chilton was Power Maxed Racing’s Mikey Doble in 12th, the duo being over a second off the pace.
After topping the time early on, One Motorsport’s Josh Cook ended up in 15th, just under a second and a half adrift of Sutton after failing to improve his time from the first half of the session.
Tom Ingram elected not to try and put in a competitive lap time, the Hyundai driver instead completing ‘housekeeping’ in the inclement conditions as he completed 11 laps but didn’t post a true lap time.
Second practice gets underway at 12:00 BST.
