Colin Turkington kept his Dunlop MSA British Touring Car Championship defence alive with victory in the final race of the day at Silverstone.
The Northern Irishman started third on the grid behind James Cole and Rob Collard, the latter bursting into the lead with the fast-starting BMW 125i.
Cole was usurped into Brooklands and Luffield by Turkington’s Team BMR Volkswagen CC, before the reigning champion then moved into the lead with a bold late-braking move up the inside of his former team-mate into the same Brooklands right-hander.
Turkington was unchallenged from then on after a restart to clear up a big shunt involving Dan Welch and Hunter Abbott, the former’s Proton Gen-2 turned around at Becketts where the Audi of Abbott collected it and then the barrier in a heavy impact.
Collard and team-mate Sam Tordoff then engaged in an intense duel for second spot, making contact at Brooklands with Collard hanging onto the spot.
Behind, pole-sitter Cole was given a tag by Jason Plato‘s BMR Volkswagen CC at Luffield, leaving the Motorbase Performance man falling down the top 10 as the Honda Yuasa Racing pair also made their way by in their pursuit of championship rival, Plato.
Collard, warned for track limits late in the race, soon surrendered second place to his charging team-mate Tordoff, but the pair then swapped back as the latter could not catch Turkington, who claimed a fourth win of the season ahead of the WSR duo.
Fourth went to Plato ahead of his Honda rivals Gordon Shedden and Matt Neal, while Mat Jackson charged through the field from 23rd to seventh after his race two puncture.
Adam Morgan brought his Mercedes home eighth ahead of Cole, the pair enduring scrapes in their own battle while Aiden Moffat came out on top in the duel with Tom Ingram despite contact twice occurring between the two.
Aron Smith was the latest to suffer a puncture meanwhile in the third BMR Volkswagen, the eventful encounter seeing race two winner Andy Priaulx handed a drive-through penalty while Jack Goff was another who failed to finish.
Shedden now leads the championship by 23 points from Plato with three races at Brands Hatch to go, Turkington 32 adrift while Neal sits 37 behind.
