Formula E an "option" for King following recent Dragon test

King is completing the majority of the 2019 F2 season for the MP Motorsport squad - and also raced in the Indianapolis 500 for Rahal Letterman Lanigan Racing - in what he calls a "stop-gap" season for his career.

The British driver recently tested for Dragon as part of its private pre-2019/20-season FE manufacturer-allocated testing programme, and the team has one more seat for that championship to fill after it announced Brendon Hartley as one of its racers last week.

When asked about the Dragon test by Autosport, King said: "We got a half decent amount of running, all good.

"It was quite easy to just jump in and drive. Obviously there was a lot to learn with the software side of things, the buttons and the settings, everything that goes with that.

"Driving-wise, over one flying qualifying lap it seemed quite comfortable for me to get in it and go.

"I did a bit of simulator time with the guys beforehand and went through all the processes and systems so I was a little bit ahead jumping in the car.

"I had to rush off to a certain Formula 2 race [the recent round in Hungary] so I've not managed to have a proper debrief, but I think it went positively.

"I'm looking at a lot of different options. I don't think I've made any secret that IndyCar is one of those options, Formula E is one of those options."

He did consider a move to the World Endurance Championship as another option for next year, having contested three events this season with Jackie Chan DC Racing in LMP2, but this looks unlikely now all full-time WEC seats have been secured.

King also explained that his multi-category season had been designed away from a "blinkered view of 'let's win F2 and get to F1'".

"I think I've had a good year and we've done a lot of things," he said.

"It was a bit of a stop gap in the bigger picture. Everything has gone well and I've been quick in everything I've done."

"There's a greater target, but not within the F2 paddock. For me it's not about winning the championship, I'm on a different side of the fence.

"I'm here to help and move the team forward.

"I missed Monaco so I knew it wasn't going to be a championship year and that hasn't been the focus of myself or the team.

"It's not been solely focused purely on F2 and a blinkered view of 'let's win F2 and get to F1'.

"I'm at a different point in my career, I'm looking at other options, doing other things and having success elsewhere."
