Villeneuve accepted an invitation to enter 2015 Stock Car Brasil's season-opening Autódromo Internacional Ayrton Senna round alongside Zonta in Shell Racing's No. 10 Chevrolet Sonic, placing 21st. He signed a contract to replace Heidfeld and partner with Stéphane Sarrazin at Venturi Grand Prix in the 2015–16 season of the all-electric Formula E series. Villeneuve had observed Formula E intently throughout 2014, admiring its bumpy city tracks. Guido Pastor called him to test a car, after which he got selected to drive. Villeneuve finished outside the top ten in the first two races and failed to start the Punta del Este ePrix due to an accident during qualifying. His relationship with Venturi cooled thereafter and they agreed to terminate their working relationship early in January 2016. Villeneuve signed a one-race agreement to return to rallycross in the 2018 season. He drove a Subaru Rally Team USA-entered WRX STi Supercar at the World RX of Canada (part of the Americas Rallycross Championship). He failed to qualify for the final following two accidents sustained during the second semi-final.
