Mueller is returning to Formula E for Season 9, after a 2-year spell in DTM. In 2014, Mueller secured a drive with Audi Sport Team Rosberg, a series in which he has remained ever since. Between 2014 and his FE entry, Mueller has experienced a varied racing career, splitting his time across Stock Car racing, GT, Rallycross and DTM.

However, Mueller is no stranger to FE – making his debut in the official rookie test in Marrakesh in January 2018, where he topped the timesheets for the session. During the 2018/19 campaign, Mueller stepped up to a full-time drive for Dragon’s alongside rookie Brendon Hartley, competing until Berlin E-Prix. The following campaign, he completed the first half of the season, scoring his first FE podium in Valencia. Will Mueller’s wealth of racing experience bring him success in Season 9?
