Extreme E founder and CEO Alejandro Agag has conceded he would "love to have Ferrari" join the series in the wake of McLaren's commitment to the all-electric SUV championship.
McLaren announced it is to join Nico Rosberg, Lewis Hamilton and Jenson Button in fielding a team next year in a series that champions sustainability and diversity.
The championship has a limited number of team slots at 12 and with McLaren taking the 10th, there could be a rush for independent teams or even manufacturers to also compete.
"Well, of course, I would love to have Ferrari," Agag responded when asked if the Italian outfit was an option.
"You have seen the news lately that Ferrari is going to do an electric Ferrari."
Assessing McLaren's arrival, Agag added: "The news is the biggest in the short history of Extreme E.
"I want to welcome McLaren, I want to welcome Zak [Brown] - well he is already in the championship - but yeah, we will have some more surprises, maybe for season two.
"We will wait because this news is big enough to give us the momentum. Extreme E, this championship is growing all the time, to be so young and have, already, McLaren in the championship is amazing so hopefully, we will have some surprises soon."
Brown has no conflict of interest
Brown already has one foot in the door of Extreme E with his affiliated team United Autosports teaming up with Andretti Autosport to field Andretti United.
Brown has insisted, however, there will be no conflict of interests when McLaren joins the series.
"I am a silent partner, effectively, in United Autosports from a day-to-day running of the team," he explained.
"For me personally, it is my relaxation, it is my golf at a race weekend if I am not doing my day job so I am 100 per cent McLaren when it comes to racing activities.
"So as relates specifically to Andretti United Extreme, I will be letting them do what they do which is running the team and I will have 100 per cent of my focus on McLaren's effort."
