Arthur Leclerc and Logan Sargeant took classy victories in the respective Formula 3 and Formula 2 races.
Prema’s Leclerc passed polesitter Zak O’Sullivan early on in the F3 race after the Briton had taken pole on Friday, before Isaac Hadjar took the win in the reverse grid sprint race.
Leclerc held off O’Sullivan before pulling nine tenths in front in the final couple of laps, leaving the Carlin driver to battle away with Oliver Bearman, Caio Collet, Hadjar and Jack Crawford for second.
It was the third win of Leclerc’s F3 career as older brother and Ferrari driver Charles watched on with pride.
“It was a fantastic race,” said Arthur.
“We set everything in motion to take the lead and win.
“Managing the tyres wasn’t easy, but we got there, it’s going to be a great battle right up to the end of the season.”
Sargeant claimed a lights to flag win following a splendid performance in F2, but the big talking point was the early collision between Roy Nissany and Dennis Hauger.
The reigning F3 champion was pushed off the circuit by the Israeli, and the Norwegian was a passenger as he hurtled down towards the sausage kerb at the Vale Chicane.
He bounced off the kerb and was launched up onto the halo of Nissany, with the safety device, introduced in 2018, undoubtedly saving the 27-year-old’s life.
Nissany was given a five-second penalty for his dangerous move on Hauger, and has also been awarded three penalty points, bringing his total to six.
“Having considered the matter extensively, the Stewards determined that Car 16 left the track at Turn 15 after making an error,” said the stewards.
“The Driver re-joined the course at the exit of the corner and rather than focusing on a safe merge into traffic, made an unpredictable and unsafe move to defend his position that initiated the contact with Car 1.
“Car 16 was wholly responsible for the collision and fully accepted blame for the incident.”
Sargeant withstood some pressure from Theo Pourchaire at the end of the race, but held on to become the first American winner in the feeder series since IndyCar driver Alexander Rossi in Sochi in 2015.
“I think after being extremely good here in F3 in 2020 I knew it was a great opportunity,” said the Williams junior driver.
“I was very confident in the car that Carlin gave me. It was a long, hard-fought weekend, Theo put pressure on in the race but I got it done.
“It’s obviously a good confidence boost as well, yeah, it’s awesome.”
A special mention must also be given to Jonny Edgar, who finished the F3 race eighth for Trident on Sunday morning having taken several months out to battle Crohn’s disease.
