Alain Prost has sold his stake in the e.dams Formula E outfit he co-founded in 2014 with partner Jean-Paul Driot to focus on his F1 commitments with Renault.
Between the burgeoning electric series and his involvement with the French manufacture in F1, the four-time world champion admits he had a lot on his plate.
"It was difficult to do everything with Formula E and F1, even physically with all the travelling," Prost told French daily L'Equipe.
"It turns out that when Renault made the decision to focus on F1, it made sense that I follow with about the same timing."
The F1 legend - a firm believer in the future of Formula E - will retain a working relationship with the series however, remaining on a strategic panel.
Assessing Renault's current state of affairs in Grand Prix racing, Prost said the works outfit has initiated the second stage of its development.
"We are about where we thought we would be," he said.
"It's a first step, and the second one starts now."
