FIA President Jean Todt insists that Grand Prix racing will never become an all-electric championship like the burgeoning Formula E series.
"It's impossible," the Frenchman told La Presse newspaper.
"F1 is an absolutely different discipline," he insisted.
Todt said he is a great supporter and fan of Formula E, but he thinks F1 took the right path by heading in the hybrid direction a few years ago.
"It is a huge step forward compared to what we had before," he said.
However, Todt has hailed the progress made by Formula E since its inception has been "remarkable".
"We have a dozen manufacturers who want to get involved, and have been approached by some of the biggest cities in the world," he said.
"Today there are brands like Renault that are in F1 and Formula E."
"I am confident that one day Ferrari will follow suit, and we would like to see that."
