Renault eyes sponsors for Senna race debut

Renault reserve drivers Senna (L) and Grosjean

(GMM) Bruno Senna could soon replace Nick Heidfeld in injured regular Robert Kubica's Renault race seat.

According to Auto Motor und Sport, team owner Gerard Lopez spent some time before the Canadian grand prix in reserve driver Senna's native Brazil.

The Luxembourg businessman was reportedly looking for sponsors, on the assumption 27-year-old Senna is drafted in to replace German Heidfeld, who is under pressure by the Enstone based team to up his pace.

Renault figures have played down recent rumors of financial trouble, but the German magazine insists the team "desperately needs money", including to pay outstanding bills to its engine supplier.

It is believed, however, that 34-year-old Heidfeld's place is not immediately in doubt, despite him crashing out in Montreal after hitting the rear of Kamui Kobayashi's Sauber.

"Until the crash, his race had been perfect," said team boss Eric Boullier.
