Formula E is on course to become an open formula in its fifth season, 2018/19, when it is planned that each driver will use only one car during the 45-minute races.
The championship has laid out what series boss Alejandro Agag is calling a “five-year road map” to achieve the goal of ending the practice of drivers swapping between cars mid-race.
The first step is to allow development of the powertrains in 2015/16 and batteries in 2016/17, while mandating the use of the existing Spark-Renault SRT_01E chassis.
The road map will also allow for an increase in the amount of energy that can be released from the battery. It will go up in steps from the current 28kw/h to 33kw/h in seasons three and four, and up to more than 40kw/h for season five in 2018/19.
