Toro Rosso's 2009 car will hit the test tracks at some point after the launch of sister team Red Bull Racing's RB5.

Sebastien Buemi, so far the Faenza based squad's only confirmed driver for the forthcoming season, suggested a date for the debut of the Ferrari-powered STR4 has not yet been fixed.

Although using different engines, Red Bull's two teams both use an otherwise identical chassis, designed by Adrian Newey and the Milton-Keynes based Red Bull Technology.

When asked about STR's plans, 20-year-old Swiss Buemi told the British broadcaster ITV: "I know that the Red Bull will come out on February 9, so I suppose we'll be a bit later than that, but I don't know exactly when."

Following testing duties in Portugal at the wheel of the 2008 car, Buemi this week returned for a short stay to Bahrain, his official residence.

Albeit not yet at the wheel of a 2009-specification car, Buemi said dominating the top of the test time sheets has been "very good for my self-confidence".

"But now we have to think of this coming year; it's going to be tough," he told the Gulf Daily News.

"We are quite confident. We just got the chassis and it looks good, and we'll see if we can run it before the end of February."
