On 24 June 2015 ahead of the London ePrix, Team Principal Mark Preston confirmed that team would continue to use the McLaren powertrain from the inaugural Formula E season in the 2015–16 season, to focus development on other areas of the car. In doing so they became the first team to take this approach, in the hope that the older powertrains would provide greater reliability than their rivals while exploring other areas where performance gains could be made, such as software.
