Former champion Jacques Villeneuve has approached McLaren with view to test driving after losing his drive with BAR.
"We have been approached by Jacques Villeneuve with regards to a role with the team in 2004," a spokeswoman for McLaren confirmed today. "However, no meaningful discussions have taken place."
Villeneuve, the 1997 world champion for Williams, is without a drive for next season after being replaced at BAR by Japan's Takuma Sato.
The 32-year-old Canadian did not compete in this month's season-ending Japanese Grand Prix after asking to be released by BAR and has not spoken publicly about his plans since then.
However, his manager Craig Pollock, who runs a CART team, was quoted in Australia at the weekend as saying that Villeneuve would test for McLaren next year and race for another team in 2005.
Britain's Motorsport Newsweekly today reported speculation that Pollock might be planning to put together an all-American team for 2005, possibly with Mercedes engines badged as Chrysler.
Mercedes are McLaren's Formula One partners. McLaren currently have two official test drivers, Austrian Alexander Wurz and Spaniard Pedro de la Rosa.
Wurz has been persistently linked to Jaguar as a likely team mate for Australian Mark Webber next year.
The McLaren test job has been a useful springboard for drivers seeking to keep their careers alive.
France's Olivier Panis took it in 2000 after losing his seat at Prost and went on to return to racing with BAR and Toyota.
McLaren were third overall last season with Finland's Kimi Raikkonen runner-up in the drivers' championship.
