Sutton equalled the record of four titles held by Andy Rouse and Colin Turkington, and became the first driver in history to scoop the BTCC crown in rear and front-wheel-drive machinery.
The Alliance Racing Ford Focus ST star had to endure a nervy finish though – a late safety car left Sutton looking vulnerable to attack from the Excelr8 Motorsport Hyundai i30 N of Ingram, who still had a lap of hybrid boost available to Sutton’s zero.
There were two laps of green-flag racing to the chequered flag, and Ingram had a sniff at the NAPA-liveried Ford into Surtees on the first of those.
Ingram saved his hybrid until the final tour, but had run out of tyre grip and Sutton held on to take the flag by 0.603 seconds.
Poleman Sutton also had a challenge at the start from fellow front-row starter Rory Butcher in his Speedworks Motorsport Toyota Corolla.
Butcher hung on around the outside at Paddock Hill Bend and Druids, allowing Ingram to sneak up the inside and, with his shorter line, demote the Scot to second.
Ingram even had a stab at Sutton into Surtees, but the leader set fastest lap of the race on the second tour, and he and Ingram put a huge amount of daylight between themselves and the rest.
