In October 2018, it was announced that W Series parent series, the Deutsche Tourenwagen Masters, would be returning to Zolder for the first time since 2002 and, as a consequence, the W Series would also race there. Following her victory in the previous round, Jamie Chadwick entered the weekend with a 7 point lead over fellow Briton Alice Powell, with a further 3 point gap back to Spain's Marta García.
Practice
FP1 would be a dry session. Jamie Chadwick would continue her run of form from the previous round at the Hockenheimring, finishing ahead of Emma Kimiläinen by just over half a second, followed closely by Beitske Visser with Jessica Hawkins showing marked improvements from the opening round to finish the session fourth. Vittoria Piria brought out the only red flag of the session with a spin into the gravel. The second free practice session was held in mixed conditions. The session was delayed by 10 minutes, with the unpredictable Belgian weather bringing rain late into the session. All representative times were set early, with Visser outpacing Chadwick by three tenths of a second ahead of Marta García and Tasmin Pepper; the South African improving from 18th in the opening session. Most competitors would end their sessions with the onset of rain, however Gosia Rdest proved the exception in an attempt to gain wet-weather mileage. As in Hockenheim, the series reserve drivers Sarah Bovy and Vivien Keszthelyi would run in free practice. They would finish 12th and 10th respectively in the opening session, however technical issues would sideline Hungarian driver Keszthelyi in the second session, with Bovy ending FP2 in 15th. Later on Friday, local driver Bovy would receive the call-up to join the regular field in the Saturday race.
Qualifying
Ahead of qualifying, Kimiläinen would be forced to pull out of the event after it was discovered that her accident with Megan Gilkes in the previous event had re-ignited a neck injury sustained in a Scandinavian Touring Car Championship accident three years prior. She would be replaced with second reserve driver Keszthelyi, bringing the field back up to 19 cars. Jamie Chadwick would claim her second pole position of the year by just over a tenth of a second from Beitske Visser, who had led the majority of the session.
Race
The race began under confusing circumstances. At the conclusion of the formation lap, Sarah Bovy's car pulled up a long way behind the grid with smoke pouring from the engine. The flag-waving marshal at the back of the field gave the all clear, but Bovy managed to re-start her car and drive into her last-placed grid slot before the light sequence. Starting second, Beitske Visser would get the jump on pole-sitter Chadwick, and the rest of the field would get away cleanly – however Gosia Rdest would make a jump-start and dive into the mid-pack at turn one, forcing Fabienne Wohlwend and Tasmin Pepper onto the dirty outside line and dropping to the back of the top ten. The safety car would be deployed as the mechanical issues became terminal for Bovy, with the Belgian not making it off the grid in her home race. After a single lap behind the safety car, the race got underway again. Visser would remain in the lead from Chadwick, however at the end of the lap Esmee Hawkey would make an ambitious move on Rdest at the Bolderbergbocht for 7th, with the pair tangling wheels and crashing out of the race. In the lead up to the same corner, Sabré Cook would bump into the rear wheel of Viven Keszthelyi, sending the Hungarian reserve driver into the barriers and also out of the race. The safety car was deployed once again, and Cook would later receive a drive-through penalty for her involvement in the incident. At the restart, Visser would pull away at the front, leaving Chadwick to defend from Alice Powell. Further down the field, Miki Koyama would again prove her overtaking prowess by passingCaitlin Wood for 8th at the Kleine Chicane, having started 13th. Marta García meanwhile would begin to form a train, with her fourth place under attack from Sarah Moore, Pepper and Wohlwend. Liechtensteiner Wohlwend would attempt a move on Pepper at the Bolderbergbocht, however would make a significant lock-up and fell into a no-mans-land between the South African and Koyama. With a handful of laps remaining, Chadwick locked her rear wheels and ran wide at the Ickx Chicane, allowing Powell to close up. The Britons would go into combat, spending most of laps 16 and 17 side-by-side with both holding the upper hand at various points. At the flag however, it would be Visser who would win her first open-wheel race since 2013 ahead Chadwick and Powell, followed by the group of García, Moore, Pepper and Wohlwend, the latter having regained time in the closing laps. Koyama, having made good progress to 8th early would fail to advance any further, with Vittoria Piria finishing in 9th and Naomi Schiff would claim the final point having benefitted from Caitlin Wood running through the gravel on the final lap.
