Austrian team Zele Racing will field three drivers in the 2015 Auto GP season opener at the Hungaroring.
Full-season signing Andres Mendez will be joined by ex-F1 driver Antonio Pizzonia and GP3 graduate Luis Sa Silva.
Pizzonia, 34, did 20 races in F1 between 2003 and 2005. A Stock Car Brasil regular since 2007, he had several outings in Auto GP over the recent years and won two races.
“I really enjoyed the race weekend in Estoril last year,” said Pizzonia. “Michael [Zele] and his team are great to work with and the car is great fun to drive.”
Sa Silva, 24, earned a best finish of seventh in two seasons of GP3 and was on the podium on his Auto GP debut with Zele in last year’s finale.
“I am delighted Zele Racing gives me the chance to race in Budapest,” said the Angolan. “We are still negotiating with our major sponsors to secure an all-season deal. But if I do well in Hungary, things should probably be easier.”
Meanwhile, Auto GP have secured another experienced racer in Christof von Grunigen, who appears to be set for a full season with new team Paolo Coloni Racing.
The 23-year-old had podium finishes in FR2.0 NEC and Alps in 2011 and did a six-race stint in Auto GP last year.
