Jul.30 (GMM) 23-year-old Romain Grosjean appears to have moved another step closer to securing his grand prix debut.



Amid reports of a terminal falling-out between Flavio Briatore and Nelson Piquet, the French-Swiss reserve driver Grosjean was this week asked by Renault to conduct driving duties at a straight-line test.



The session took place on the runaway of the Imperial War Museum in Cambridgeshire (UK).
