Stoffel Vandoorne has secured his first Formula E World Championship after securing a second-place finish in the final race of the season in Seoul. 

Vandoorne’s title triumph was also complemented by Mercedes’ second successive teams’ title, as it signs off from its three-season foray in Formula E on a high.

Edoardo Mortara drove a great race to secure victory for Venturi in their last race before they become Maserati next season.

The Swiss-Italian driver took the lead after a great move into Turn 1, where he gave Da Costa the dummy and dived down the inside to take the lead of the race.

He wasted no time in building a lead over Dennis, who went through with Mortara when he passed Da Costa and was left relatively untroubled by the Avalanche Andretti driver in the opening laps of the race. A one-second gap by the end of lap 5 was almost up to two seconds a few laps later, and it continued to grow until a safety car wiped out his advantage.

Da Costa and Dennis came to blows at Turn 22 – where Dennis left the front of his Andretti down the inside and tapped the Portuguese driver into the wall.

The incident was quickly thrust under investigation and, although Mortara was able to extend the gap to over three seconds, Dennis invested his energy into catching up in anticipation of a time penalty.

Dennis was duly given the five seconds in penance, which eased the pressure on Mortara and allowed the Geneva-born driver to cruise to victory in Formula E’s 100th race.

Dennis nonetheless built enough of a gap over Robin Frijns in fourth to stand on the podium, while Oliver Askew capped off an excellent day for Andretti with fifth place – granting the American squad sixth in the teams’ championship over next year’s powertrain supplier Porsche.

Jean-Eric Vergne was sixth ahead of Evans, who could only finish seventh after a disappointing qualifying proved fatal to his slim championship chances.

Nick Cassidy claimed the fastest lap and finished eighth ahead of Sebastien Buemi, while da Costa recovered from his Turn 22 scuffle to finish in 10th – as Sergio Sette Camara was dropped out of the points for weaving in front of Jaguar stand-in Norman Nato.

Lucas di Grassi sustained a puncture and could only finish 11th, which rocked Venturi’s teams’ title chances considerably, while Alexander Sims recovered from his 60-place grid penalty to end his Formula E career in 12th.
