In yet another rain-hit race today, Rory Butcher took the final victory of the year, as Ashley Sutton won his second BTCC title.
After conditions improved for the second race of the day, rain struck again to make the last BTCC race of 2020 a tricky one for the drivers.
Aiden Moffat started on pole position after his name was pulled out in the reverse grid draw, with Chris Smiley starting alongside him.
Championship contenders Colin Turkington, Dan Cammish and Sutton started ninth, 10th and 12th.
Butcher took the race lead on the first lap, managing to get past the two drivers ahead of him, with Moffat dropping to third.
It was a poor start for Senna Proctor, who dropped to 10th on lap one after starting fifth.
Butcher began to extend his lead soon after gaining first place, with the gap second standing at 3.7s on lap three.
Turkington put his BMW up into fifth place, with Cammish was holding onto ninth place with Sutton right behind him.
The most notable incident of the race came early on during lap four, after Team Parker Racing driver Stephen Jelley went off into the gravel and ended his 2020 season with a retirement.
Dan Cammish began to get through the pack on lap five, overtaking both Moffat and Ollie Jackson through the final couple of corners.
Sutton quickly followed, overtaking his teammate Moffat and getting into ninth place.
Cammish continued to make up places, getting past Turkington at Surtees on lap eight and moved up into sixth.
Sutton also made up a place on the same lap, with a move on Jackson to take eighth position.
For the next 11 laps it was a case of being patient for Sutton and sitting behind Turkington.
Further up the field Tom Ingram moved up into second place on lap 13, getting ahead of Adam Morgan, the TripleR Racing driver dropping to third and just ahead of Cammish.
Ingram began to close the gap on Butcher, with the gap sitting at 4.1s at the end of lap 17.
Further back, Sutton’s patience paid off on lap 19, as Turkington opened the door for him to get past through Paddock Hill Bend and into seventh.
Turkington’s struggle continued as Moffat then moved ahead of the BMW on lap 22, taking eighth place.
As the chequered flag was waved on lap 24, Butcher took the race win in Round 27, 2.8s ahead of Ingram, with Jake Hill finishing in third.
Cammish ended the race in fourth place, followed by Morgan.
After making an overtake on lap 22, Sutton finished the race in sixth place, ahead of Josh Cook’s Honda Civic.
Sutton’s teammate Moffat came home in eighth, with Turkington behind him.
Jackson rounded off the final top-10 of the season in his Motorbase Performance Focus ST.
In a weekend with conditions not ideal to debut in the BTCC, Brad Philpot ended his third race of the weekend in 22nd.
Sutton’s sixth place finish was sufficient enough for him to win his second BTCC title, finishing the season 14 points ahead of Turkington.
