The 2015–16 FIA Formula E season was the second season of the FIA Formula E championship, held from 24 October 2015 to 3 July 2016. The season sees the introduction of eight manufacturers, who are 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 successfully defended teams champion. After ten rounds, Sebastien 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.
The second season was planned to again feature 10 teams that were essentially identical from the inaugural season. But, the withdrawal of Trulli after failing to enter the first two races left 9 teams competing for the 2015-16 season. Additionally, there are 8 manufacturers of power trains that work together with or are part of the individual teams. Initially only Team Aguri decided to keep the power train from the previous season, while Dragon use the Venturi power train. Due to the regulations, all teams use the same chassis as in the first season. The 8 manufacturers were homologated by the FIA in August 2015. After troublesome preseason testing, Andretti decided to revert to the power train from the inaugural season.

The season was scheduled to include 11 races, held between October 2015 and July 2016. The final calendar was approved by the World Motor Sports Council in October. However, in May 2016, the Moscow ePrix was cancelled "due to recent and unforeseen circumstances related to road closures", reducing the season to 10 races.
