The 2018–19 season saw the introduction of the all-new Gen2, second generation Formula E car, which boasted significant technological advances over the previous Spark-Renault SRT 01E chassis – its power output rose from 200 kW to 250 kW and top speeds rose to around 280 km/h (174 mph). The arrival of the Gen2 car also saw an end to the series’ mid-race car-swaps.[1]
