Portuguese driver da Costa already has GP3 experience with Carlin after competing in four races for them in 2010. He's also competed in British Formula Three and last November took part in the GP2 Final exhibition race at Abu Dhabi, as well as working with Force India at the F1 Young Driver tests that followed.
"I'm really looking forward to this season with Carlin - I know the team really well and it get on so well with everyone, it's like a family!" said da Costa. "Our pace in testing has left me confident for the start of the season and I can't wait for the first race in May."
Over at Atech CRS GP, team principal David Hayle was delighted to confirm 20-year-old Hungarian racer Tamás Pál Kiss to the team's line up: "I really believe we have our greatest chance of challenging for the GP3 title this year and I expect he will greatly assist our GP3 rookie Ethan Ringel as he embarks on only his second season in car racing," he said.
Kiss had experience in the Hungarian Formula Renault Championship and Renault 2.0 Suisse before moving to Atech for the British Formula Renault 2.0 series in 2009. More recently he spent 2011 in the GP3 Series competing for Tech 1 which saw him claim a race win in Spain. With Tech 1's departure from the series, Kiss has returned to Atech for 2011 and is very happy to be reunited with old friends.
“I'm really pleased to be returning to a team I know and to be working with some of the people I built up such a good relationship with in 2009/10," he said. “After a successful season last year, it's nice to come back to Atech and after a good test at the end of last season, and a positive pre-season test in Spain recently, I'm confident ahead of the 2012 season."
With the first race of the GP3 Series due next month at Barcelona, the driver line-up is rapidly filling up. Other than RSC Mücke Motorsport - which is yet to confirm any drivers for the 2012 season - there are now only single seats left at Status GP, Jenzer Motorsport, Trident, Carlin and Atech to be filled.
Lotus GP have already announced their trio of Daniel Abt, Conor Daly and Aaro Vainio for the forthcoming season, while MW Arden will be fielding Mitch Evans, David Fumanello and Matias Laine. Marussia Manor Racing's drivers will be Dmitry Suranovich, Fabiano Machado and Tio Ellinas.
