Formula E racing is fairly new to the market as it only started in 2014 and at the time every car on the track was identical except in color and sponsor. Audi was one of the original sponsors of a Formula E racing team, but as the sport has grown over the past few years some teams are expanding and asking that automakers build their own race cars to give some differentiation to the cars on this circuit. This is quickly becoming one of the fastest growing racing divisions in the world and may eventually branch off into other areas of racing.
