Longo clarified that he remains a fan of F1, but believes the championship may have taken the wrong direction with its latest regulations.
"The only thing I can say is, as I always say, I'm a big fan of Formula 1," he added. "I definitely believe that they decided to go for certain regulations that probably are damaging their spectacle and their show a little bit.
"I think they are getting closer and closer to us. We do not have exclusivity, but we do have expertise already on that."
While F1 drivers reported running out of electrical energy on straights in Melbourne, particularly due to the lack of heavy braking zones, Formula E cars have not encountered similar issues. Drivers in FE are able to stay in the higher power Attack Mode (350kW) for as much as six minutes without losing speed on straights.
Asked about that contrast in Formula E, Longo said: "Yes, we can use eight minutes or six minutes of Attack Mode and the car doesn't slow down. I think they need to be back to where they are. They are noise, they are full power, they are breaking the latest [technologies], this is what Formula 1 is about.
"We are a completely different proposition. We have been presented like that since day one. It's not one or the other; it's both of them. But the problem is that they try to become more Formula E.
"In my opinion, as a fan, I think they are making a mistake. I definitely believe that they should stick to what they are, to their principles."
