Brazilians Ricardo Zonta and Nelson Piquet Jr. have been confirmed as Renault's test drivers for the 2007 season. Thirty-year-old Zonta will be an important asset in Renault's adaptation to the new tyre regulations for next year, when all teams will use Bridgestone rubber. Twenty one-year-old Piquet, the son of three-time champion Nelson, will join Renault after two seasons in the GP2 series, where he will fight for the title in this weekend's Italian Grand Prix. "It is a pleasure to welcome Ricardo and Nelsinho, who each bring different qualities to the team," said team boss Flavio 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 One. "2007 is the start of something new for Renault, and we believe it will be an exciting season." - - - - Carol
