Ferrari junior driver and dominant Formula 2 championship leader Charles Leclerc looks set for a first drive of current-spec Formula 1 machinery in the post-Hungary test.
Leclerc leads this year's F2 title race by 67 points, more than the equivalent of a perfect weekend, after just six rounds of his maiden campaign in the championship.
The Monegasque has already won five races in F2, including four Feature Races, and most recently won the weekend's opening race in Britain by nearly nine seconds.
Given that he is a member of Ferrari's young driver academy, Leclerc's performances have prompted speculation about a 2018 F1 seat.
Rumours that he could even make an immediate jump to a Ferrari race seat have now escalated, with the team electing to test him out in Hungary.
Although there has been no official announcement yet, sources have confirmed that Leclerc will take part in one of the two Hungaroring test days.
With neither of Ferrari's current drivers under contract for next year, the test will give the team a good chance to properly evaluate Leclerc's speed and technical feedback in the current car to help judge what to do with him for 2018.
Leclerc already has experience of F1 machinery, having completed a Ferrari test in a 2014 car at Fiorano last year as well as conducting four Friday morning practice runs for Haas at grands prix last season.
