Formula E: Da Costa claims Buenos Aires victory

Antonio Felix da Costa emerged from the debris cloud to secure his first Formula E win on the Buenos Aires street circuit on Saturday. The Amlin Aguri racer took the win on an afternoon where the hot ambient conditions were matched by the temperature of the contest over the second half of the race.

For the first 15 laps it had been a relatively processional affair, with Sebastien Buemi leading Lucas di Grassi and Nick Heidfeld. But Karun Chandhok's trip into the Turn 10 wall right before the car swap – a crash that was sparked by a rear suspension failure – the entire complexion of the race changed and leading became a bad luck omen.

Barely had the Chandhok's debris been swept up and the safety car been recalled when Buemi slammed into the wall at exactly the same place, ending what was shaping up to be a dominant weekend for the e.dams driver and handing the initiative to di Grassi. His time in the hot seat lasted exactly two laps before he became the next victim of the same piece of barrier, and moved Heidfeld into first place.

Heidfeld's first task as leader was to remain clear of Sam Bird, who was doing all he could to rattle the German's cage before veering into the pitlane to serve a drive-through for ignoring a red light at the pit exit.

Bird rejoined back in 12th, and left Heidfeld to concentrate on trying to open a gap over da Costa and Jean-Eric Vergne – a task that kept him busy for six laps before he, too, was issued a drive-through, this time for pitlane speeding.

That handed da Costa the lead with just one lap to go, and a chaotic multi-car battle for the minor podium places meant that P1 was the safest place to be: Jaime Alguersuari, Vergne and Daniel Abt were all hip-checked out of potential top three places over the final couple of laps, opening the door for Nicolas Prost – who had been nowhere just a few laps earlier – to claim second.

Completing the top three was Nelson Piquet Jr., whose afternoon was mostly spent recovering from a miscommunication with his team that left him pitting a lap later than he would have liked to when the safety car came out.

Alguersuari and Bruno Senna completed the top five ahead of Vergne and Bird, whose recovery to seventh was capped off with the fastest lap of the race.

America's Marco Andretti finished a lap down in his series debut for Andretti Autosport, losing track position under a caution period. He was classified 12th after the Aguri team's Salvador Duran was excluded for exceeding the allowed power usage. Despite a problematic day, Andretti said he found the challenge intriguing.

"It was an interesting weekend and the series is quite unique!" said Andretti. "I enjoyed myself; it's a great challenge coming from IndyCar, with very low grip, but I think that the technology is exciting.

"I think there is a lot to improve on from my end as far as the conserve mode and the overall pace, so I am not that thrilled with 12th for the first go-round, but hopefully we can build on that.

"During the race, as soon as I saw the yellow I came in – and in IndyCar we would have been right at the front, but for some reason they held me behind the pace car and we are yet to figure out why, so that was frustrating. If we can just tidy it all up for the States, we'll have a good package."
