For the first time since its inception, the championship featured multiple power unit manufacturers, allowing the use of Mercedes and Volkswagen engines. It was intended to have equalised performance of the powerplants, in terms of both power and torque like in the GT3 racing.[1] But the equalisation was not successful as the teams that used Toyota engine which was tuned by Piedrafita had a lack of power in comparison with Mercedes and Volkswagen engines. The situation led to the withdrawal of the teams after the first round and switching to the Mercedes and Volkswagen engine prior round at Spa.[2]
Team Motopark driver Marino Sato won the title after the first race at Barcelona, having won eight races, including series of six wins in row in Spa, Hungaroring and Spielberg, while his team clinched the title after the second Spielberg race.[3] Top rookie Liam Lawson was Sato's closest challenger, winning four races throughout the season. His fellow Red Bull-staplemateYuki Tsunoda won a race at the Hockenheimring, Teppei Natori was victorious in the second race at Catalunya, Billy Monger became the first double-amputee to win a race in single-seaters when he won the Pau Grand Prix, and Toshiki Oyu won both races at a one-off appearance in Silverstone.
An eight-round provisional calendar was revealed on 31 August 2018.[1] The calendar features six circuits from 2018 schedule. While Autódromo do Estoril and Circuito de Jerez are not present in the current version of the calendar, Hockenheim made its debut as a Euroformula Open Championship round. The date of the Spa round was altered on 29 November 2018.[38] On 10 December 2018 was announced that Pau Grand Prix will make debut in the extended nine-round Euroformula Open Championship schedule.[39]
