From Season 6 of the ABB FIA Formula E Championship, the use of twin motor generator units will be banned following Friday's FIA World Motorsport Council meeting in Paris.
While teams used a set powertrain configuration in Season 1 of the all-electric championship, from Season 2 onwards, teams have been able to design and develop their own powertrains with freedom over how many motors they use.
DS Automobiles and NIO trialled the twin motor design in Formula E's first generation, however, for the series' present Season 5 campaign, switched to a single motor configuration.
Presently on the 2018/19 grid, Nissan e.dams is the only team to use a twin motor set up, with the double MGU offering improved power dispersal at the rear of the car although the weight of the vehicle is increased as a result.
Notable for its acceleration out of corners, Nissan's Season 5 IM01 package has gained the attention of rival teams, however, has yet to win a race although the Franco-Japanese squad has registered more pole positions this season than any other team.
For Season 6, it is understood that Nissan e.dams was set to again use a twin MGU set-up, however, with this arrangement now getting banned by the FIA, the team will have to revert to a single motor layout.
Alongside the outlawing of twin motor generator units, a number of additional changes for Formula E's 2019/20 season were also confirmed, with the series seeing an extra 10kW power increase in Attack Mode while drivers will now have a set amount of energy subtracted during safety car and Full Course Yellow periods, meaning that drivers are unable to save energy when driving at low speeds.
