Sebastien Buemi is continuing his title defense in Formula E with win after win. After crossing the finish line first in Hong Kong and Marrakech, he has repeated the act in Buenos Aires and became first driver to win three consecutive races in Formula E.
After qualifying it seemed that Lucas di Grassi (Abt Schaeffler Audi Sport) would be the driver to beat, but he only managed to hold on to first place for a few corners, before being passed by Jean-Eric Vergne (Tcheetah) and Buemi (Renault E.Dams). Not long after Buemi passed Vergne (whose Tcheetah car is identical to Buemis' Renault E.Dams) and built a comfortable lead that he kept during the mid-race car change an all the way to the finish. Di Grassi, dropped to fifth before pit stops, but climbed to third during the car change. However, his team release him form the garage right into the path of Nelson Piquet Jr. (who eventually crossed the finish line in fifth, behind Nicolas Prost), so Brazilian's third place was in danger while that action was investigated by the stewards. Fortunatelly for di Grassi, they decided that the move was legal.
Buemi's win means that he's still leading the championship table, and his maximum score of 75 points places him far in front of the competitors. Same goes for the team championship: Renault E.Dams has a comfortable lead over Abt Shaeffler Audi and Mahindra.
