Alex Fontana will return to the GP3 Series with Jenzer Motorsport this weekend at the Hungaroring.
The Swiss driver previously raced for the team at Spa-Francorchamps in 2011, claiming a sixth-place finish in the second race.
Last year's European F3 Open champion, Fontana was weighing up a full-time move to GP3 for 2012 before eventually settling on the FIA Formula Two Championship.
Fontana lies ninth in the F2 standings with two race weekends remaining. He claimed a double podium finish on his debut at Silverstone but has failed to score a similar result since, despite showing strong pace.
Fontana will use his GP3 appearance as preparation for the next round of the F2 season at the same Budapest circuit at the start of September.
The 19-year-old will drive the car raced by Jakub Klasterka in the opening two rounds and then by Facu Regalia in Silverstone. Clashing commitments for Regalia meant that the car was unused last weekend at the Hungaroring, just as it was in Valencia.
He joins Romanian Robert Visoiu and fellow Swiss driver Patric Niderhauser (who has so far won two races in his rookie campaign) at Jenzer.
“I've been in constant contact with the Jenzer team since the beginning of the season,” said Fontana. “Due to a series of circumstances including overlaps with the Formula 2 championship dates, so far it's been impossible to get a taste of GP3. I'm therefore delighted that the team turned to me on this occasion.
“For a young driver, racing in the shadow of the Formula 1 circus, is a unique and incredibly stimulating experience. We know that an extremely difficult task awaits us. Some of the world's best drivers from my age group race in GP3 and I’ve never even seen the Hungaroring track.
“I last tried the car during winter testing back in November. I’m hoping I’ll be able to adapt quickly giving that we’ll only have one free practice session. Apart from that I'll simply be trying to do my best and race without any mental pressure. I know that I'll be able to count on the support of a very professional team.”
Team boss Andreas Jenzer added: “We had Alex with us last year for the race at Spa where he immediately took the car into the points zone. So we already know him and we have the advantage that he knows the team and the way we work. We don't expect miracles, but we're sure that he’ll make his contribution to the team, a contribution that I hope will prove to be important in terms of the future too.”
