Sargeant, managed by Infinity, was unbeatable throughout the event, having won the qualifying, all the heats, the pre-final and the final.

He was challenged by Tom Joyner at the start of the race and even had to give up the lead temporarily before retaking it on Lap 3.

The 15-year-old showed superior pace afterwards to build a lead of 3.4s until the checkered flag.

Joyner finished second, having withstood race-long pressure from Clement Novalak, who completed the podium.

Despite only lining up 14th on the grid, championship leader Pedro Hiltbrand charged through the field to take fourth with Karol Basz in fifth.

With one more round to go, Hiltbrand continues to lead the standings by just six points from Sargeant.
