Former Formula 1 driver Mark Webber believes that it is impossible to see where Formula E will be in 10 years time given the series' current growth and the rapid expansion of EV technology.
Webber, 41, raced in F1 from 2002-2013, taking nine wins and 42 podiums from 215 race starts when driving for Minardi, Jaguar, Williams and Red Bull Racing.
Having retired from motorsport and racing at the end of 2016 after finishing in fourth place in the FIA World Endurance Championship, Webber currently holds a representative role with Porsche who will join Formula E for Season Six.
While Porsche is set to join the Formula E grid in 2019, the all-electric single seater series will also see Mercedes EQ join while HWA AG and Nissan will be joining the series come December for the start of Season Five, the latter replacing Renault on the grid in a partnership with the French e.dams squad.
While Formula E is currently seeing huge growth rates with the championship becoming more and more competitive to drive in, Webber struggled to imagine where the series will be in one decade given the championship's current rate of acceleration.
"I don’t think it’s even possible [to imagine where Formula E will be in 10 years]," Webber told Motorsport Week.
"The curve that we’re on, the acceleration curve in terms of the business side, the entertainment side, where we’re going with transferring technology from Formula E cars to street cars, I mean in 10 years time it’s going to be a whole new space.
"I mean, for us [Porsche], just talking a little bit about our brand obviously, it’s a perfect synergy with Mission E car coming and for Formula E.
"That whole electromobility and the investment into that space in terms of Monday-Friday on the road and race cars is going to be very very different in 10 years time,” he added.
Looking ahead of Porsche's arrival in Formula E, Webber was unsure as to whether he will have a role in the manufacturer's programme:
"[I'm] not sure yet but of course I’ve always got my Porsche hat on – I want them to do well," he said.
"We’ve got great people advising us already. It’s a while away yet but at the moment, everyone is in place to get the job done."
