It's time for round four of the season, the Julius Baer Mexico City ePrix, which is being held on the famous Autodromo Hermanos Rodriguez in the Mexico capital.
A little over a month has passed since the last installment of the championship in Argentina, and the pressure is mounting for the teams to stop Renault.edams and Sebastien Buemi from running away with it.
The story so far
Reigning champion Sebastien Buemi has got off to an almost perfect title defence with a hat-trick of wins in the opening three races.
Buemi is now in such a position of dominance, he will lead the championship after the race regardless of the result. Lucas di Grassi remains his closest challenger, and scored his first Julius Baer Pole position last time out. Another first in Buenos Aires was a podium finish for TECHEETAH, following second place for Jean-Eric Vergne.
Nico Prost has been fourth in every race so far this season, which leaves him third in the standings. Felix Rosenqvist has taken scored two Visa Fastest Laps for Mahindra as well as pole and a podium in Marrakech, which has left him fifth in the points behind Vergne.
Sam Bird's second place for DS Virgin Racing in Morocco has him sixth in the standings, while the only other driver to have finished on the podium – Nick Heidfeld who was third in Hong Kong for Mahindra – is seventh.
The Mexico City ePrix
The Autodromo Hermanos Rodriguez is the only permanent racing facility on the Formula E calendar, albeit in a very different form to the version used in Formula 1 and the World Endurance Championship.
The layout is based on a modified version of a short oval that was created at the track for the local stock car racing series. It utilises the famous Peraltada final corner and the spectacular stadium section, and the track is just over two kilometers in length. It has been slightly altered for this season, with the Turn 1 chicane reprofiled to make for better racing.
Jerome D'Ambrosio started last year's race from pole and led for the opening half of the race. However, after the mid-race car change, Lucas di Grassi used his FanBoost perfectly, to grab the lead down the start/finish straight and into Turn 1.
Di Grassi then pulled away leaving D'Ambrosio to battle wheel-to-wheel with Buemi. The Belgian defended hard, and there was minor contact as things became heated. Buemi finally did pull off a move, but ran off the track in the process and was forced to let his rival back through.
They finally crossed the line side-by-side, with D'Ambrosio a nose ahead. When di Grassi was disqualified after failing post-race checks, the Dragon Racing driver was declared the winner.
