2015 ISOWC IndyCar Series
The 2015 ISOWC IndyCar Series was the 5th season of the International Simulated Open Wheel Championship. Its premier event was the ISOWC Indy 500, which was planned to take place on 16th of August but was cancelled. Michael Dinkel was the defending champion but did not participate the season.
The season was put into a halt after Watkins Glen due to low participation. There was talk to cancel the rest of the races except pushing back the ISOWC Indy 500 date to 4th of October, but ultimately the premier event did not happen neither.
After 15 out of 19 originally planned races, Michel de Jonge won his first title in the series while also being crowned the road course champion. Oval champion Chad Simpson finished runner-up overall.
The series did not return for a 6th season in 2016. ISOWC was eventually revived 6 years later in 2021, starting at Watkins Glen, where the series folded in 2015.
