No shortage of energy in mastering Monaco

Sebastien Buemi and his Renault-powered e.dams fought off a furious challenge from Lucas di Grassi of Audi Sport ABT to claim his fourth FIA Formula E Championship win of the season in Monaco on Saturday and extend his points lead to 15.

Buemi made a perfect start from his first pole position of the campaign and quickly established a comfortable lead over Brazil's di Grassi, who in turn was easing away from compatriot Nelson Piquet Jr, driving for China's NextEV NIO.

Piquet was locked in a battle with Jean-Eric Vergne of China's Team Techcheetah, who swarmed all over him. The Frenchman was clearly anxious to make a move and stop the front two from getting away, so he tried an ambitious move around the outside of the Turn 3 hairpin.
