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.
