Sebastien Buemi set the pace once again in the second free practice session at the Autodromo Hermanos Rodriguez ahead of Saturday’s Mexico City ePrix.
Formula E championship leader Buemi left his 200kW lap until late in the 30-minute session, but made full use of it by producing a lap of 1:03.341 to finish four-tenths of a second clear at the head of the field.
Jean-Eric Vergne and Sam Bird had both led early on for DS Virgin Racing, but the session was interrupted after 13 minutes when home favorite Salvador Duran suffered a possible software issue on his Aguri car, leaving him stranded on the track.
Once the Mexican had been recovered under a red flag, the session resumed with most of the drivers heading out to complete their 200kW laps, using all of the power permitted in practice.
ABT Schaeffler teammates Daniel Abt and Lucas di Grassi rose to first and second place respectively with their qualifying simulations, while ex-IndyCar driver Mike Conway slotted into third place for Venturi.
However, their times were not enough to keep Buemi at bay as he re-claimed P1 with three minutes remaining, doubling up after topping first practice earlier in the morning.
Renault e.dams teammate Nicolas Prost ended the session fourth behind di Grassi, while Conway held on to P5 ahead of NEXTEV TCR’s Oliver Turvey.
Jerome d’Ambrosio finished up in seventh place ahead of Stephane Sarrazin, while Vergne and defending champion Nelson Piquet Jr. completed the top ten.
Qualifying for the Mexico City ePrix takes place in less than one hour’s time ahead of the race at 5pm ET.
