Formula E car
The Formula E car is an open-wheel auto racing car, powered by an electric motor that its sound – 10 decibels higher than a gas engine touring car[1] – has a high-pitched sound that's similar to a plane taking off.[2] The Formula E car is designed to take part to the FIA Formula E Championship.
Tech specifications
Even though this category is open to all designers,[3] the only licensed Formula E model, for the inaugural season (2014-2015), was the Spark-Renault SRT 01E. The electric part is assembled by Renault[4] and the chassis, designed by Dallara, is assembled by Spark Racing Technology.
- 0-100 km/h : 3 seconds (approximately)

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[7] 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.[8]
