The 2018 season was the third organised by the British Racing Drivers' Club in the United Kingdom.
The championship featured a mix of professional motor racing teams and privately funded drivers, and also featured the 2-litre 230-bhp Tatuus-Cosworth single seat race car in the main series.
The season commenced at Oulton Park on 31 March and ended on 14 October at Silverstone Circuit, after eight triple header events for a total of twenty-four races.
The series supported British GT at all events, excluding the finale at Silverstone Circuit.
Race two, which reversed the order of the race one finishers, providing they set a lap time within 103% of the fastest driver, will be awarded extra points for positions gained from drivers' respective starting positions.
