Defending champion Colin Turkington was quickest again in the second British Touring Car Championship practice session at Croft, with another late improvement putting him top ahead of Josh Cook.
In similar fashion to the opening session earlier in the day, it was MB Motorsport’s Jake Hill who led the way from the midway point onwards, before fellow Honda driver Josh Cook fired in his best effort to go quickest in the final quarter of the session.
Despite some late drizzle falling, that time was then bettered in the final minutes by Team BMW’s Turkington, who put in a 1:21.768 to top the session, going around four tenths quicker than his benchmark time in first practice.
Thruxton race three winner Cook’s time remained good enough for second, putting him 0.057s behind Jake Hill and almost a tenth-and-a-half clear of Hill’s FK2 Honda Civic.
Ciceley Motorsport’s Adam Morgan continued his strong practice form with fourth position in his Mercedes-Benz A-Class, while Toyota Gazoo Racing UK’s Tom Ingram bounced back from a disappointing opening practice in which a manifold issue on his Toyota Corolla hampered his running to complete the top five.
Turkington’s team-mate Tom Oliphant was next in sixth ahead of current championship leader Ash Sutton who placed seventh in his Laser Tools Racing Infiniti Q50, just 0.285s adrift of Turkington’s best time.
The returning Mike Bushell made amends for an off in first practice by putting his Team HARD-run Volkswagen CC in eighth position just over four tenths off the pace, while Motorbase Performance’s Rory Butcher managed one better than his earlier result with ninth position.
Title contender Dan Cammish endured a far-from-straightforward session in his Team Dynamics-run Honda Civic, with a couple of off-track excursions in the final sector, and ultimately managing to complete the top ten runners with a time 0.458s off the benchmark pace.
He placed ahead of Halfords Yuasa Racing team-mate Matt Neal by just nine-thousandths-of-a-second, while Bobby Thompson was 12th fastest in his Trade Price Cars Racing Audi S3.
The Excelr8 Motorsport duo of Senna Proctor and Chris Smiley placed in 13th and 14th positions respectively, while Stephen Jelley’s Team Parker Racing BMW 125i M Sport rounded out the top 15.
Next up for the British Touring Car Championship at Croft is qualifying, which is scheduled to get underway at 14:55 BST.
