2018 GP3 Series

The 2018 GP3 Series was the ninth and final season of the second-tier of Formula One feeder championship and also ninth and final season under the moniker of GP3 Series, a motor racing feeder series that runs in support of the 2018 FIA Formula One World Championship and sister series Formula 2. This was the final contested season of GP3, as the series united with the FIA Formula 3 European Championship to form the FIA Formula 3 Championship.

2018 was the final season that the Dallara GP3/16 chassis package—which débuted in the 2016 GP3 Series—was used in competition, as a brand new chassis package for the FIA Formula 3 Championship was introduced in 2019.

After finishing 3rd in the final feature race of the last season of GP3, Anthoine Hubert was crowned the 2018 GP3 Champion. ART successfully defended their teams' title over Trident after the first race at Sochi, winning the teams' title in eight of the nine seasons of GP3.

Runner-up Nikita Mazepin won 4 races; in Barcelona, Hungaroring, Spa-Francorchamps, and Yas Marina. After having four rounds with Jenzer Motorsport, David Beckmann moved to Trident before the summer break and took 3 race wins. Champion Anthoine Hubert, Callum Ilott, Leonardo Pulcini, and Pedro Piquet all won 2 races. Also, Giuliano Alesi won the second race in Spain, Jake Hughes won for the third time in the series at the Red Bull Ring, and Dorian Boccolacci, who drove for MP Motorsport before being promoted to their Formula 2 team won the sprint race at the Hungaroring.
