Carlos Sainz Jr kicked off his return to Formula Renault 3.5 action by setting the pace in free practice on Friday at the Hungaroring
The Red Bull junior - who raced at Monaco and Spa earlier in the season - is set to complete the campaign with Zeta Corse.
He enjoyed a brief spell at the top of the times with fellow Red Bull stablemate Antonio Felix da Costa early on, and he then set the quickest time of the day in the final minutes of the afternoon session.
Sainz's lap denied potential Sauber 2014 Formula 1 racer Sergey Sirotkin the top spot, after he had moved into first place with 10 minutes to go.
Will Buller completed a good day for Zeta by jumping up to third in the closing stages, moving him just ahead of morning pacesetter Marco Sorensen, who dominated the last FR3.5 event at Spielberg.
Championship leader Kevin Magnussen completed the top five, just ahead of Will Stevens, who fell from second to sixth during a frantic spell of action in the closing stages.
Two drivers who didn't get involved in any of the late-session excitement in the afternoon were da Costa and Magnussen's title rival Stoffel Vandoorne.
The pair enjoyed a long spell at the top of the times during the middle of the session, but they were shuffled down to seventh and ninth respectively in the final few minutes.

The 2015 Formula Renault 3.5 season will be notable for being the last with the French company's backing but also produced a worthy champion in Oliver Rowland. PETER MILLS evaluates this year's crop of drivers
Last year's field was extraordinary and hard to match, but the Formula Renault 3.5 grid will still have plenty of talent this season. Glenn Freeman runs through the field ahead of this weekend's season opener
Landing the Fortec seat that took rising star Robin Frijns to the 2012 FR3.5 title was already a good sign for Stoffel Vandoorne. Then McLaren took him under its wing. Peter Mills tells Vandoorne's story so far
