The Formula E car is an open-wheel auto racing car, powered by an electric motor. The Formula E car is designed to take part in the FIA Formula E Championship.
Technical specifications
Even though this category is open to all designers, the only licensed Formula E model, for the inaugural season (2014-2015), was the Spark-Renault SRT 01E. The electric components are assembled by Renault while the chassis is designed by Dallara, and the car is assembled by Spark Racing Technology.
For season 2 (2015-2016), teams can now use other designers for the electric engine, engine control unit, gearbox and suspensions
Whereas the original FIA battery specifications included a 200-kilogram (441 pound) cell-weight limit, a 200-kW peak power limit, and a maximum usable energy of 28 kWh, the specifications for the 2017-2018 and 2018-2019 season call for a battery at 250 kg (551 pounds) and 54 kWh energy, and peak power goes up to 250 kW. The cells are to be made by Sony, the integration by Lucid Motors, and track handling by McLaren.
A Formula E engine is said to be 10 decibels higher than a gas engine touring car and produces a high-pitched sound that is similar to a plane taking off.
