The New Zealander dominated the E-Prix after wresting the lead from pole sitter Andre Lotterer on the opening corner, holding off the challenge of DS Techeetah’s Antonio Felix Da Costa and Nissan e.dams Sebastian Buemi in third.
The result leaves Evans top of the drivers’ standings by a singular point, with his British team now sitting second in the team’s championship behind German rivals BMW i Andretti Motorsport.
Lotterer started the race on pole position, with the German edging out Evans in the Super Pole showdown by just six of a hundredths of a second to lead the field for new manufacturer Porsche.
But it was Evans who claimed the lead moments after the lights went green, overtaking Lotterer on the first corner of the Autodromo Hermanos Rodriguez circuit, in a robust move which saw contact between the two drivers and damage to Lotterer’s Porsche.
Lotterer fell from the front to the back of the grid before retiring to cap a mixed day for Tag Heuer Porsche following a maiden pole position in Formula E, but a pointless race for the German team.
A sell-out crowd in Mexico City was treated to a dramatic E-Prix, with a series of crashes forcing the retirement of seven drivers, including Envision Virgin Racing’s Sam Bird, who hit the wall when second and heading for a podium finish with just three minutes of the race remaining.
Former Championship leader Stoffel Vandoorne also crashed out in the dying stages to cap a miserable day for Mercedes-Benz EQ, with teammate Nyck De Vries also crashing out of the E-Prix.
Audi’s Daniel Abt – who missed qualifying after a major crash in free practice – started the E-Prix but later retired after an eventful day that saw him visit a local hospital for precautionary X-ray checks following a high-speed collision caused by a software failure to the brakes.
Formula E returns on Saturday 29th February, with the Marrakesh E-Prix.
