e.dams-Renault’s Sébastien Buemi will await the results of an post-session investigation after topping the first practice session of the Buenos Aires ePrix. Buemi will be joined by China Racing’s Nelson Piquet Jr and Mahindra Racing’s Karun Chandhok, with the pair also under investigation.
Buemi saw off the challenge of a late burst of pace from Chandhok, who with five minutes remaining topped the times with a 1min 10.917secs, a time that saw him go over a second clear at the top.
The e.dams driver responded instantly, his lap of 1min 09.475secs proving to be over a second quicker than the Mahindra racer.
Chandhok fell down the order and it was the Audi Sport ABT pair of Lucas di Grassi and Daniel Abt who took second and third, with the pair setting times of 1min 09.831secs and 1min 10.579secs respectively.
Chandhok would eventually finish in fourth and was the last of the drivers to go below the 1min 10secs mark. e.dams’ Nico Prost took fifth with his lap of 1min 11.605secs enough to see off the time of 1min 11.952secs set by Piquet Jr in sixth.
Seventh was Virgin Racing’s Jaime Alguersuari thanks to his lap of 1min 12.154secs, narrowly beating the eighth placed Jerome D’Ambrosio of Dragon Racing and his time of 1min 12.306secs.
Behind D’Ambrosio was Amlin Aguri’s Antonio Felix da Costa, a 1min 12.360secs edging out the 1min 12.464secs of Venturi GP’s Nick Heidfeld.
Falling just short of the top ten were the likes of Andretti Formula E Team’s Jean–Éric Vergne, Virgin’s Sam Bird and Mahindra’s Bruno Senna.
Notable incidents in the first session saw a temporary red flag caused by Virgin’s Bird, while new boy Marco Andretti of the Andretti team marked his first outing in a Renault–Spark with a lap time of 1min 14.071secs that secured him 19th.
