Tom Chilton and Esteban Guerrieri shared the wins but it was Thed Björk who came out on top of a tense title showdown in Qatar as the provisional FIA World Touring Car champion for 2017.

In his second full WTCC campaign with the factory Polestar Cyan Racing team, Björk started the final weekend of the season 6.5 points in front of Norbert Michelisz.

But a brake issue in qualifying left his Honda-driving rival out of contention as Björk drove without fault to touring car racing’s biggest prize on the back of standout wins at Monza and the Nürburgring Nordschleife earlier in the year.

Fifth in the Opening Race, the Swede was heading for a podium in the Main Race before handing the place back to team-mate Nicky Catsburg following an earlier gesture by the Dutchman.

And during a night of Swedish celebration, Volvo Polestar won the FIA World Touring Car Championship for Manufacturers with Catsburg and Yvan Muller – on his return to the WTCC – helping to ensure it beat Honda by 28.5 points. Néstor Girolami also performed strongly for the team in 2017, winning from pole in China.

Elsewhere, Tom Chilton beat fellow Briton Rob Huff and his Sébastien Loeb Racing team-mate Mehdi Bennani to the WTCC Trophy for independent racers, winning the Opening Race to boot ahead of Bennani and Kevin Gleason, with the American claiming his first WTCC top-three.

Esteban Guerrieri marked an impressive debut WTCC bid with the Main Race victory for Honda and was joined on the podium by Tiago Monteiro, the former world championship leader he replaced after the Portuguese was injured in a testing crash in September. Huff and Catsburg completed the podium amid emotional scenes.

John Filippi finished a career-best fourth in the Opening Race with Muller sixth and title contender Michelisz down in ninth from P11 on the grid. Tom Coronel, Kris Richard, Yann Ehrlacher, Ryo Michigami, Dániel Nagy and Zsolt Dávid Szabó completed the Opening Race finishers.

In the Main Race, former ETCC champion Richard made up for his hesitant start in the first counter, passing Muller with an audacious move to finish sixth on only his fourth WTCC start.

Filippi and Michigami rounded out the points scorers, with Coronel just missing out in P11. Bennani retired with damage following first-corner contact with Muller.
