The Renault F1 team has signed Ricardo Zonta and Nelson Piquet Jr. to assist Giancarlo Fisichella and Heikki Kovalainen in the development of their 2007 car.
Flavio Briatore, who has also just agreed a two-year extension to remain at the helm as team boss, has welcomed the move and reckons that both will be an asset next season as test/reserve drivers.
"It is a pleasure to welcome Ricardo and Nelsinho, who each bring different qualities to the team," said Briatore. "Ricardo will have a key role to play in preparing for 2007, while Nelsinho has shown this year that he deserves his place in Formula 1. 2007 is the start of something new for Renault, and we believe it will be an exciting season."
Zonta joins Renault from Toyota, where he has been a test/third driver for the last four seasons. The Brazilian made his F1 debut with BAR back in 1999 and to date has competed in 36 grands prix.
"Ricardo's proven track record, combined with extensive technical knowledge, will be major assets in the development of the 2007 challenger and its adaptation to the new tyre regulations," added a statement from the regie.
Piquet Jr. meanwhile certainly has the pedigree as the son of three-time world champion, Nelon Piquet. Piquet Jr has been racing in the GP2 series this season, F1's feeder category and has taken four race wins and five pole positions so far to put him second in the championship, with two races remaining.
"Zonta and Piquet are a balance of youth and experience. Ricardo has done an excellent job for Toyota in recent seasons, and his knowledge of the Bridgestone tyres will be invaluable as we make the transition for the 2007 season. Allied to his speed and experience, this will be a major asset for the team," added FB. "As for Nelsinho, we had the chance to sign him - and didn't want to miss out. He has been one of the best two drivers this year in GP2, and he clearly has what it takes to succeed. Now, he needs to grow as a Formula 1 driver, and Renault is the perfect place to do it."
