The2015 Buenos Aires ePrix, formally the2015 FIA Formula E Buenos Aires ePrix was aFormula Emotor race held on 10 January 2015 at thePuerto Madero Street Circuit inPuerto Madero,Buenos Aires,Argentina. It was the first edition of theBuenos Aires ePrix and the fourth championship race of thesingle-seater,electrically powered racing car series'inaugural season. The race was won byAntónio Félix da Costa.

Nick Heidfeld,Jean-Éric Vergne, andBruno Senna were voted to receive the FanBoost (an extra 30 kW for five seconds per car).

Sébastien Buemi started onpole position, withJaime Alguersuari andNick Heidfeld behind him. Going into the first hairpin, Heidfeld managed to brake later and overtake Alguersuari on the outside. The field seemed to be free of incidents throughout the first couple of laps, butMichela Cerruti was seen entering the pits, possibly after making contact withBruno Senna. Meanwhile, championship leaderLucas di Grassi overtookSam Bird for fourth position and Heidfeld deployed his FanBoost at the main straight, but he failed to take the lead from Buemi. On lap 7, di Grassi passed Alguersuari and moved up to third, and passed Heidfeld in turn five, on lap 14. Heidfeld fell further down the order when he had to use the run-off area at turn 8 and was overtaken by bothVirgin drivers.

The first major incident of the race happened on lap 16, whenKarun Chandhok's right-rear suspension broke and he hit the wall. Just before the race was neutralised, Heidfeld managed to take his position back from Bird, and Alguersuari was seen entering the pits with five others. Those who waited a lap to come in, including Buemi and di Grassi, were stuck behind Cerruti, because overtaking was not permitted under yellow flags. Because thesafety car picked up the leader at the moment Buemi was in the pits, there was much confusion about who was in the lead. However, it was still Buemi, di Grassi, and Heidfeld at the top of the standings, so on lap 21, every driver not in the lead lap was told to pass the safety car and catch up with the rest of the field.

Green flags showed with thirteen laps to go. Almost immediately, however, the leader Buemi hit the wall on the inside of turn 8, broke his suspension and had to retire. The top three was now filled by di Grassi, Heidfeld, and Bird, but the latter quickly received adrive-through penalty for ignoring the red lights at the end of thepit lane. On lap 26, di Grassi's suspension broke in the same fashion as Chandhok's had done, sending another race leader into retirement. The safety car was not deemed to be required, because both Buemi and di Grassi had managed to park their cars safely.

The last three laps sawJean-Éric Vergne aggressively overtaking Alguersuari for third place and Nick Heidfeld being given a drive-through penalty for going over the pit lane speed limit, makingAntónio Félix da Costa, who had been relatively invisible throughout the race, the fourth race leader in ten laps. Meanwhile, Alguersuari was being attacked byNicolas Prost,Nelson Piquet Jr. andDaniel Abt. Vergne joined them when he missed his braking point twice and fell back from second to fifth. Abt tried to overtake Prost on the dirtier side of the track, but ended up hitting the back of Alguersuari instead and retiring with one lap to go. Félix da Costa took victory, with Prost second, Piquet third, Alguersuari fourth, and Senna fifth; Vergne had had to slow down to save energy.
