BMW's Colin Turkington eased to a comfortable race three victory despite having to contend with two safety car periods at Thruxton.
Turkington made a lightning start in his typically fast off the line BMW and immediately exited turn one in second position behind Fabrizio Giovanardi, who made a textbook start from pole.
Midway through the first lap however Turkington had already breezed his way past the Airwaves Focus to make a quick getaway.
Turkington then after was never threatened despite having his lead cut twice after two massive shunts from Ollie Jackson and the barrel rolling Simon Belcher at Church corner triggering the safety car.
The former BTCC-champion judged each restart to perfection leaving Giovanardi unable to provide an opening.
Airwaves Racing picked up an outstanding double podium with Mat Jackson leading the way in second with Giovanardi third.
Giovanardi held off a ferocious multi-car battle for the final step on the rostrum, which was led by Andrew Jordan who couldn't quite forge a way past the widest car on the circuit.
Gordon Shedden was fifth for Honda with Jack Goff following just behind the Scot in sixth.
Aaron Smith produced a gutsy recovery drive to finish seventh. The Irishman was aided by the chaos which ensued ahead involving Matt Neal and Rob Collard exchanging paintwork at the complex – putting Neal out of the race.
Collard and the Honda's spent most of the race nose-to-tail,embroiling themselves in a highly charged panel-barging battle.
Mercedes' Adam Morgan survived an early race scare and brought his Wix Racing A-Class home in eighth.
Morgan was sent into a slide by Goff's Vauxhall on lap one in the tight and twisty complex section. His Mercedes, however, unwittingly ended championship contender Jason Plato's race as the Wix man recovered his sideways car – damaging Plato's MG rear suspension beyond repair.
Consequently Sam Tordoff was left to carry the MG flag but struggled to make any real impression on the frontrunners to end his day ninth.
Collard ended his incident packed race miraculously in the top ten even after leaving the circuit on two occasions.
