While a second successive win in the Champ Car World Series would hint at a fourth title for Sebastien Bourdais, the Frenchman's hopes of finally breaking into Formula One may take another positive step this summer.

Having tested with Scuderia Toro Rosso over the winter, reports in America suggest that the former Renault prot?g? could be in line for a second outing in July, as manager Nicolas Todt pushes for his inclusion in the top flight next season. Speculation suggested that Toro Rosso was interested in taking Bourdais for 2007 after he impressed over three days at Jerez - running less than two seconds from pacesetter Lewis Hamilton despite no recent F1 experience - but the Frenchman was tied to the final year of his Champ Car contract with Newman/Haas.

However, with that deal coming to an end, Todt is understood to be pushing his client's candidature for a ride in F1, although many believe Bourdais' ship to have sailed, having been passed over by the likes of Renault and Williams in past seasons. Indeed, the Frenchman went as far as officially turning his back on F1 just over a year ago, before relenting in order to accept the Toro Rosso test.

Bourdais' chances of landing an F1 seat, particularly with Toro Rosso, would be enhanced if he could bring sponsorship to the team, but it may be that Red Bull will be sufficiently impressed by his natural ability to continue pumping funds into the squad.
