Antonio Felix da Costa clinched victory in an action-packed Buenos Aires ePrix ahead of e.dams-Renault’s Nicolas Prost and China Racing’s Nelson Piquet Jr.
The Amlin Aguri driver kept clear of trouble and slowly made his way into the lead as his rivals fell out of contention.
Both polesitter Sebastien Buemi and Lucas di Grassi retired from the lead with suspension failures suffered at the tight Turn 8 and 9 chicane.
Venturi’s Nick Heidfeld looked favourite to clinch victory in the closing stages but a drive-through penalty for speeding in the pitlane scuppered his chances.
