Dennis Hauger won the first British Formula 4 race of the weekend as championship contenders Ayrton Simmons and Kiren Jewiss ran into trouble at Snetterton.
Simmons, who qualified second, was promoted to pole after Patrick Pasma took a grid penalty he carried over from Croft and started from the pit lane.
The JHR Developments driver held the lead comfortably in the early stages of the race as Hauger and Jewiss battled for second with Paavo Tonteri close behind.
Jewiss managed to get ahead of the Red Bull junior, but Hauger fought back and the pair made contact. The championship leader was sent into a spin and was left stranded at the side of the track as the rest of the field sped part. He managed to get going again, but was running more than 20 seconds behind the rest of the field.
Tonteri, who started sixth, was promoted to second and immediately began to challenge Simmons for the lead, but a small mistake dropped the Double R Racing driver back to eighth.
Jack Doohan was the next to bring the challenge to Simmons, and the first to break his race lead. The pair came together, allowing Hauger and Sebastian Priaulx through.
With Doohan and Simmons continuing to fight in the closing stages of the race, Hauger and Priaulx were unchallenged to the chequered flag to take an Arden 1-2 and Priaulx’s first podium since Donington Park.
A small mistake from Doohan as he tried to pass Simmons allowed the charging Pasma to pull alongside. Pasma was pushed slightly wide, with two wheels running over the grass, and he came close to losing control of his car. He managed to hold on, but dropped back to eighth.
Doohan returned to challenging Simmons, almost pushing him over the line, but the Brit managed to stay ahead.
Tonteri finished fifth, ahead of Sebastian Alvarez and Pasma.
Jonathan Hoggard, Josh Skelton, and Jamie Sharp completed the top 10.
