Da Costa goes top of the Drivers’ Championship with the victory to become the fifth different winner from the first five races of the season and make it nine different winners in a row counting last season.
As Championship leader heading into Marrakesh, Evans was looking to build on the most dominant performance of the season in Mexico City but his team miscalculated the start of his qualifying lap so he was unable to set a time ensuring he started from the back.
The grid got off to a clean start and it was Mercedes-Benz EQ’s Nyck de Vries found himself in third early on only to be pulled to the back of the grid by a drive-through penalty.
Vergne had been absent from track most of the week – even missing Free Practice 1 – with illness and was even tested negative for coronavirus but produced his healthiest drive of the season climbing from 11th to third within the first 20 minutes of the race.
Halfway through Guenther took the lead from Da Costa but the German mentioned on team radio his suspicions that the Portuguese had purposely allowed him to pass to move into his slipstream and contain energy – confirmed by Da Costa later.
Da Costa did take back his lead after saving energy and activating ATTACK MODE and began opening up a gap of more than a second.
Towards the middle of the pack Evans had put his qualifying woes behind him to climb up to 11th, just a fraction away from the points with ten minutes to go in the race and the only man of that 11 with an ATTACK MODE left.
Vergne and Guenther produced a stunning battle for second place as Evans continue his climb to end the race in sixth place.
The German had the last say as he overtook Vergne on the final lap with the Frenchman with less than 0.1% energy remaining as he crossed the line in third place.
But the day belonged to his teammate Da Costa who won his third Formula E race before the series moves onto Rome on April 4.
