The most likely progression for Doohan is that he concentrates on the Alpine reserve role and is fully embedded in the Enstone team next year, while continuing his test programme in a two-year-old car.
While he has attended all Grands Prix as a reserve this year, and took part in FP1 in Mexico on Friday, his F2 commitments meant that his main focus was on the latter series at weekends when both were on the bill.
However there also remains the possibility that he dovetails his F1 role with an WEC programme.
Alpine’s hypercar project presents an obvious opportunity, but Doohan insists that no decision has been made thus far.
The Australian currently lies fourth in the F2 standings after an at times difficult sophomore season with Virtuosi saw him score two feature wins.
"Currently I won't be competing iIn F2 for next year,” he said. “It doesn't seem realistic, with the situation and everything that's sort of gone on.
“I've made the most of it, I think we've done a great job with what's been in my control. So doing [a third year] wouldn't be much of a gain.
“My two years in F2 haven't necessarily gone exactly to plan. I'm sure everyone can say that, it never really does. But through that, and through the bad moments, the highs, with what's been in my control, I think I've done well, and been able to show my capabilities.
“Doing another year in F2, if you win it, you're expected to, if you don't, you may as well... There's not much to gain. So there's all to lose and not much to gain.
"Currently I've got no direction of WEC or anything confirmed. So I'm still very much in line of F1, the team is still pushing for that and staying within the team, and still pushing for a F1 seat. So this is my route. And I'm sure I'll get there.”
