Calendar changes
The rounds held at Autodromo do Estoril, Autodromo Enzo e Dino Ferrari, Sochi Autodrom, Marina Bay Street Circuit, Sepang International Circuit and Guia Circuit were discontinued.

The series made their debut in Georgia at the Rustavi International Motorpark which opened the season.

The provisional calendar featured a round at the Circuit de Monaco supporting the Monaco Grand Prix, but was removed as it wasn't approved by the Monegasque ASN as they had never entered negotiations to stage the race. It was replaced by Autodromo Nazionale di Monza in Italy as supporting series to the European Le Mans Series.

With the release of the TCR China Touring Car Championship the calendar slot for October, which was left vacant, was given to the Zhejiang International Circuit. In the previous two seasons the series visited Shanghai International Circuit.

The round in Hungaroring was originally scheduled on 1–2 July, but for logistics reasons it was pulled back two weeks earlier than planned. The change also meant that the series would support the Hungarian round of the Deutsche Tourenwagen Masters.
