Formula 1's Chase Carey has hit back at Alejandro Agag, the CEO of Formula E, after he claimed that the all-electric single seater championship would one day become more popular than motorsport's premier racing series.
While Formula E has had unprecedented growth over the course of the past year, becoming more popular with fans and attracting the attention of a number of prominent manufacturers in the automotive industry including Mercedes and Porsche, Agag claimed that the championship would be the only motorsport series remaining in the next 20 years.
"I'm glad he [Agag] has a crystal ball," Carey told Germany's Sport Bild.
"Formula E is not our competitor. It represents something that matters to all of us – the environment – but I see it as more of a street party than a sports event.
"People who've been there say they had fun because there was music and good food, but Formula 1 is watched worldwide and we now have the opportunity to take it to a new level.
"And I believe other series can help us, because they create interest. But the top series is and remains Formula 1," he added.
This is one of a number of clashes that Formula E and Formula 1 have had over recent weeks, with the prior jokingly welcoming F1 to the 21st century following its removal of grid girls last month.
