2019 FIA Formula 3 Championship

Marcus Armstrong, another Prema driver, finished second and won races at Hungaroring, Spa and Sochi.

As the championship is a spec series, all teams competed with an identical Dallara F3 2019 chassis and a bespoke tyre compound developed by Pirelli.

[7] Charouz later formed a partnership with Sauber Motorsport, which currently runs Alfa Romeo's team in Formula 1.

The final entry was awarded to HWA Racelab, who joined the series after Mercedes-Benz withdrew from the Deutsche Tourenwagen Masters touring car championship.

[18] Honda promoted F4 Japanese champion and Red Bull Junior, Yuki Tsunoda to the category with Jenzer Motorsport.

[23][24] After racing in the GP3 Series with Jenzer Motorsport and Trident, David Beckmann signed with ART Grand Prix, who also took on Renault Sport Academy members Max Fewtrell and Christian Lundgaard.

[31] He was partnered with Bent Viscaal, who was the runner-up in the 2018 Euroformula Open Championship driving for Teo Martín Motorsport, and Jake Hughes, who raced in GP3 with ART.

[32][33] After racing with them in GP3, Richard Verschoor joined MP Motorsport alongside Simo Laaksonen and reigning TRS champion and Red Bull Junior, Liam Lawson.

[37] After scoring two race wins with them in the 2018 GP3 Series, Pedro Piquet reunited with Trident and was joined by Niko Kari and Devlin DeFrancesco, both of whom switched from MP Motorsport.

His replacement at Jenzer Motorsport was Giorgio Carrara, however the Argentine could only start participating from the Spielberg round due to visa issues.

[45] Following an accident at the Monza round that left him with fractured vertebrae, Alex Peroni missed the final race at Sochi.

The ninth round held at the Yas Marina Circuit in 2018 was omitted from the Formula 3 calendar to allow drivers the opportunity to compete in the 2019 Macau Grand Prix, which was announced during the season to be a non-championship round of the FIA Formula 3 Championship, as all teams and cars were at the event.
