Swiss Formula Renault champion Zoel Amberg will join FRenault UK graduates Nick Yelloly and Marlon Stockinger in Atech CRS' GP3 line-up this season.
The 18-year-old tested for the team in the official GP3 sessions at Paul Ricard last week and has now been announced as its third driver.
Team boss David Hayle said Amberg would stay on for 2012 as well, but hoped he could fight for victories this season as well.
"We're very excited by the prospect of having Zoel join the team, as he looked very good at the tests last season," said Hayle.
"He joins us on a two-year programme, which adds stability to the plan, and we expect the first season to be a learning year. However, that does not mean we won't be trying to win right from the start."
