Turkington, with the soft option tyres fitted to his West Surrey Racing BMW 330e M Sport, got the launch from second on the grid, but the problem was he had to do it twice.
That was due to a four-car pile-up at the end of the opening lap that caused a delay of almost an hour for barrier repairs to be carried out.
Turkington had only just cleared the polesitting Motorbase Performance Ford Focus ST of Dan Cammish at the first start, but at the second attempt it was much more clear cut.
Cammish bemoaned making a mess of his getaways and bogging down, and such was the extent of this that he was down to fourth by Paddock Hill Bend behind the WSR BMWs of Turkington and Jake Hill, plus his Motorbase Ford team-mate Ash Sutton.
Sutton wasn’t finished yet, and filled a chink of light on the inside of Hill at Clearways at the end of the opening lap.
Hill attempted to fight back along the start-finish straight, but that left the door open for championship leader Cammish to move back up to third.
Sutton was on the regular medium tyre but had more hybrid use available to him than the rest of the top four – he set fastest laps on the second and third tours as he closed the gap to Turkington, but by quarter-distance Turkington was beginning to pull away again.
