Formula 1 CEO Chase Carey took a dig at Formula E boss Alejandro Agag following the latter's claim that the all-electric series will surpass Grand Prix racing in the future.
Agag believes Formula E is setting the agenda in the world of motorsport, with F1 following many of its ideas in the areas of digital presentation and social media.
But Agag also made the bold claim that his series will take over from F1 and be the last motor racing championship standing in 20 years' time. Carey pushed back on that prospect however.
"I'm glad he has a crystal ball," the F1 boss said.
"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," he added.
"And I believe other series can help us, because they create interest. But the top series is and remains Formula 1," Carey said.
