Aug.23 (GMM) Flavio Briatore is on the lookout for a new Renault test driver for 2008, according to reports.

The current occupant of the French squad's official test and reserve seat, Brazilian rookie Nelson Piquet Jr, is hoping to graduate to the grand prix grid next year.

He is already being linked with a racing role at Williams for 2008, and even Renault itself.

The French weekly magazine AutoPlus claims that F3 Euro Series championship leader Romain Grosjean is at the top of Briatore's short list of possible replacements for Piquet.

The Swiss 21-year-old, who competes with a French racing license, is reportedly also likely to move up to F1's feeder series GP2 next year, perhaps with the ART team.
