The Envision Racing driver took a lights-to-flag victory after an imperious performance in treacherous conditions having rebuffed a strong challenge from Jaguar’s Evans.
The win and sixth place finish for Sebastien Buemi means Envision has provisionally claimed the teams’ championship having been in a battle against Jaguar entering the final race of the season.
Cassidy and Evans dominated proceedings, with newly crowned champion Jake Dennis completing the podium more than 16s behind Cassidy.
The last race of the Formula E season was finely poised on Sunday at the ExCeL London’s unique indoor/outdoor circuit, with Cassidy just taking pole from Saturday’s London E-Prix winner Evans.
As well as pole, Cassidy more importantly secured three points which pivotally moved Envision clear of Jaguar in the teams’ standings prior to the race.
The field began the scheduled 34-lap race behind the safety car due to heavy rain outside the main arena, with race director Scot Elkins stating that the field would circulate for several laps before lining up on the grid for a standing start.
After three laps the safety car headed to the pits with drivers set to take up their positions on the grid, but moments later the safety car was redeployed before cars came to a stop.
Two more laps were run under caution, but with conditions still not improving the decision was taken to red flag the race.
