Dennis claims emphatic Mexico City E-Prix victory

Jake Dennis took a comprehensive victory at the Mexico City E-Prix ahead of Pascal Wehrlein and pole sitter Lucas di Grassi.

The Andretti driver made an early move for P1 before claiming a several second lead and securing the fastest lap of the race.

Dennis' race-winning move came on lap twelve. Following two early safety car periods, the Briton made an opportunistic move on the inside of di Grassi at Turn 3.

From there, Dennis was rarely troubled, and continued to build a lead of several seconds whilst maintaining an advantage on energy levels.

Wehrlein, who started the race in P6, scythed his way through the field by overtaking McLaren's Jake Hughes and di Grassi to claim second, but was unable to reel in Dennis.

With the top two spreading out, the battle for the final podium place intensified, with Mahindra driver di Grassi defending hard from Hughes and the second Andretti of Andre Lotterer.

With Hughes requiring some last-lap energy saving, he backed away from challenging di Grassi, who secured third, and conceding to Porsche's Lotterer to fall to fifth.

World Champions suffer, Frijns sustains injury

Envision Racing's Sebastien Buemi and Porsche's Antonio Felix da Costa threatened to join in the fight for the podium, but were unable to mount challenges and settled for P6 and P7 respectively.

Last season's runner up Mitch Evans could only manage P8, ahead of the second Envision Racing car of Nick Cassidy.

Reigning World Champion Stoffel Vandoorne could not recover from a low-key qualifying effort, but managed to claim a point for the DS Penske team.

There was concern for Abt Cupra driver Robin Frijns, who had an unusual crash on the opening lap of the race. The collision into the back of Norman Nato broke the Dutchman's wrist, and he will be a major doubt for the upcoming Formula E races.

Sam Bird's difficult weekend with Jaguar turned into a disaster when the Briton retired with driveshaft issues.
