Patric Niederhauser will stay with Jenzer for the 2013 GP3 campaign.
The 21-year-old joined the squad last year as reigning Formula Abarth champion.
Niederhauser was also a race-winner in a parallel part-season in Italian Formula 3.
The Swiss driver is the second GP3 returnee to sign up for 2013, joining his former Jenzer team-mate Robert Visoiu, who has switched to MW Arden.
