The Mercedes motorsport boss is positive of the all-electric championship, but admits it is still a relative unknown.
"It's an exciting new series that has come up against all odds and is doing quite okay," Wolff is quoted by Crash.net. "Electrification is not going to go away on the road and we don't know where it's going to go on the race track."
"There is a large hybrid and electric part in an F1 car already and we are serious in looking at it. We haven't spent time in the past looking at Formula E properly, but by signing the option it gives us an opportunity to look at things and find out whether it is something suitable for us going forward."
"You can see there is an interest from many other manufacturers in this series and that is logical if you are looking at what is happening in road car technology."
