Pascal Wehrlein dominated the Formula E season opener in Mexico City, leading home Sebastien Buemi, but is currently under investigation for an unspecified technical infringement.

The Porsche driver started from pole, making a clean getaway. Buemi, who started besides Wehrlein on the front row, had to fend off Maximilian Guenther’s play for second going into Turn 1.

The first change for the lead came on lap three when Wehrlein took the wider Attack Mode line, ceding position to Buemi who did the same on the following lap, but maintained the lead.

Five laps later, the race’s only safety car period came, as Buemi’s Envision Racing teammate Robin Frijns lost control on the exit of Turn 16, coming out of the Foro Sol stadium section, then smacking the Turn 17 wall. When the race resumed three laps later, Buemi took his remaining Attack Mode ti me, ceding the race lead once again to Wehrlein who was untroubled for the rest of the race, eventually crossing the line 1.164s ahead of Buemi.
