Rowland, the 2015 Formula Renault 3.5 champion, finished third in the 2017 Formula 2 championship before working as Williams’s ’18 official young driver, which included a run at the Hungaroring test.
He will make his full-time FE debut with the Nissan team at this weekend’s Ad Diriyah E-Prix alongside Sebastien Buemi.
“I don’t think it’s my aim anymore at all,” Rowland told Motorsport.com when asked if racing F1 remained his ultimate ambition.
“Formula E is going in a really good direction – it’s getting bigger and bigger. It’s exciting – I think the level of drivers is probably, on average of the 22, the best in the world.
“In F1, you’ve got exceptional people, but maybe not the whole grid is the same.
“But in Formula E, if you look at what they’ve achieved, a lot of them deserve to be in F1 at some point or another.
“So, I’m not focussing on that so much anymore. I’ve got a big opportunity with Nissan and that can be long-term, so not so much on Formula 1 anymore.”
Rowland has completed just one day in Nissan’s 2018/19 FE challenger – the final day of the Valencia pre-season test where he was a late call-up following Alexander Albon emerging as a 2019 Toro Rosso F1 candidate.
Albon subsequently negotiated a friendly release from his three-year deal with Nissan, and Rowland, who was in consideration for a 2018/19 reserve FE role with the team, was signed as his replacement.
As a result of his lack of running, Rowland explained that there was “zero” pressure from Nissan for him to succeed straight away.
“There’s pressure from myself a little bit – I want to do well,” he said.
“That’s normal, I’m a racing driver – I don’t want to go there and finish 10th or 11th, I want to go there and fight with the good guys.
“[But] they’ve made it quite clear that there’s absolutely zero pressure on me.”
When asked what his plans for 2019 had been looking like before he signed with Nissan, Rowland replied: “To be honest, I’m not really sure.
“I had some options still to do more of the reserve stuff in Formula 1 and I’d have probably found something.
“My  year was a bit messed up with the whole [Manor/Ginetta] LMP1 project, to be honest.
“I signed a deal to do that and it was a proper professional contract and stuff like that and it was a good step for me, although the car wasn’t quite ready and things went the way they did.
“It kind of stopped me from doing anything else.
“Now with the [WEC] superseason, it was difficult to try and find something.”
