Williams Grand Prix Engineering
For the first season, all teams were supplied an electric racing car built by Spark Racing Technology, called the Spark-Renault SRT 01E. The chassis was designed by Dallara, with an electric motor developed by McLaren (the same as that used in its P1 supercar), a battery system created by Williams Grand Prix Engineering and a Hewland five-speed gearbox. Michelin were the official tyre supplier. 42 electric cars were ordered by the FIA.
