The three-time champion had the soft Goodyear tyres fitted to his Motorbase Performance Ford Focus ST, and absolutely rocketed away from the field for an unchallenged victory.
It’s the first time anyone has won four consecutive BTCC races since Alain Menu when the Swiss romped to the 1997 title.
New championship leader Sutton was 2.276 seconds ahead of the West Surrey Racing-run BMW 330e M Sport of fellow front-row starter Jake Hill by the end of the first lap, and had extended that to 4.239s next time around.
By lap four the gap was over 5s, before it settled – Sutton then backed off as he took the chequered flag to cross the finish line 3.614s in front.
“We were just on the right tyre,” said Sutton. “It’s so critical those first few laps, and the soft tyre made it a bit easier.
“I managed the tyre after that because Jake was still pushing and I wanted to make sure there was enough in case there was a safety car.”
Hill led WSR team-mate Colin Turkington throughout to take second, and the trio completed a repeat of the podium from race one.
All four of the BMWs started this race on the medium tyres, and as the 12 laps wore on Turkington began to look vulnerable to the Motorbase Ford of Dan Rowbottom, who was on the soft rubber.
But the bearded Midlander was kept at arm’s length and finished fourth. And, with the top six reversed on the grid for race three, Rowbottom is the only one of those who does not have to use the slow hard tyres.
