The FIA has selected the eight manufacturers that will enter the second season of the all-electric Formula E series.
All ten teams currently competing in the inaugural season are using identical the Spark-Renault SRT_01E single-seaters, but the series will become an open championship for the 2015/2016 season.
The FIA has selected ABT Sportsline, Andretti, Mahindra, Motomatica, NEXTEV TCR, Renault Sport, Venturi Automobiles and Virgin Racing Engineering.
Each manufacturer will be allowed to develop its own in-house innovations, beginning with the development of bespoke powertrains. All teams use McLaren Electronic Systems powertrains at the moment.
In order to keep costs under control, Formula E will only allow teams to develop the e-motor, the inverter, the gearbox and the cooling system. All the remaining parts will stay unchanged.
During the third season, manufacturers will be able to develop their own batteries, with the series aiming to have races without a car change as it happens now.
"It's fantastic for Formula E to have this many manufacturers wanting to be a part of the championship after just four races, and shows great confidence in the series," said series boss Alejandro Agag.
"One of our objectives from the beginning was to promote technology competition but we cannot do that as organisers of the championship, we need ‘actors' to join and to develop technologies to fight against each other in the races.
"Through this fight we improve the technology and then with this improved technology we improve electric cars in general. We expect more manufacturers to join from season three onwards and we're already talking with many different manufactures and also OEMs."
FIA president Jean Todt added: "The gradual opening up of the regulations will promote innovation, while at the same time keeping costs under control. The solutions chosen by the manufacturers will hopefully lead to rapid development of the future-focused technologies at the heart of Formula E.
"In terms of the manufacturers chosen, we are satisfied with the quality of the applications received and the number of manufacturers becoming involved reflects the huge interest generated by Formula E."
