The 2015–16 FIA Formula E Championship was the second season of the FIA Formula E championship, held from 24 October 2015 to 3 July 2016. The season saw seven new manufacturers, who were allowed to develop new power trains, specifically the e-motor, the inverter, the gearbox and the cooling system. Nelson Piquet Jr. was the defending Drivers' Champion and Renault e.dams the defending teams' champion. After ten rounds, Sébastien Buemi won the championship by just two points over Lucas di Grassi after setting the fastest lap in the final race, where neither driver finished following an opening lap crash and several attempts to set the fastest lap in their second cars. Renault e.dams retained the teams' championship.
