Jack Doohan seals the win for Trident at the Russian Grand Prix

Jack Doohan has finished the final round of the FIA Formula 3® Championships with a win in the Feature Race, a victory in the Teams' Championship and a second-place finish in the Driver Standings.

The Trident driver started the weekend strongly and kept his fight for the individual title alive with his second pole of the season. Teammate Clément Novalak finished second, and Jenzer Motorsport's Jonathan Hoggard rounded out the top three, with both drivers having their best Qualifying for the season.

By the time the Feature Race had come around, the individual Championships had been awarded to Dennis Hauger from PREMA Racing.

Doohan and Novalak remained one and two into the first lap of the final race of the season. With Hauger in ninth, and Arthur Leclerc and Olli Caldwell out of the points, Trident looked to be in a solid position to take the Constructors Championship from PREMA.

Hauger got caught in the middle of six drivers and got tagged by Oliver Rasmussen. He was sent spinning off the track, with Trident in prime position to take the Teams' Championship.

Doohan and Novalak only had to maintain positions to win the Constructors; However, Novalak wanted to win, and the two teammates continued their battle. Novalak momentarily took first from the Australian, but Doohan retook the position down the straight.

After receiving team orders to give Novalak the spot, Doohan refused and went on to win the race. Novalak was unable to hold P2 after the constant battles with Doohan and eventually lost it to Frederik Vesti.

"I just won the final race of the year here in Sochi. I am sad that it's over, but I'm happy to end on a win and to reward the team with the Teams' Championship, their first ever," Doohan said.

"I'm happy, but we need to keep working. We didn't win the Drivers' title and I'm still disappointed with that. We will work hard and next year try and go one better."

Hauger finishes the season on 205 points, ahead of Doohan on 179, Novalak on 147 and Vesti is fourth with 138. Victor Martins finished as the highest placed rookie with 131 points in fifth.

Trident wins the Teams' Championship with 381 points, ahead of PREMA Racing on 375 and ART Grand Prix on 256.

The season may be over, but Formula 3 will return for post-season testing at Valencia in just over a month on 1-3 November.
