Without a debut grand prix victory in 2009, Toyota's future in formula one remains clouded.

In official team interviews and statements, the Japanese marque said it was committed to the sport amid the global financial crisis, and mere weeks after rivals Honda pulled out.

But in conversation with the media on Thursday, when the new TF109 racer was revealed, it emerged that the Cologne based team is under high pressure this season to deliver Toyota's first win since it entered the sport in 2002.

"Toyota's message has been very clear: we carry on with F1, however we all have a great responsibility to try to bring home the maiden victory, which could be decisive for the future," Italian driver Jarno Trulli told his country's sports daily La Gazzetta dello Sport.

Toyota management echoed the unambiguous 2009 target of a race win, and team president John Howett underlined the importance of achieving this goal.

"We have to win, I think that's clear. This organisation really only exists to win so we have to realise that we need to really make a change and deliver some outstanding performance this year," he told Reuters.

Trulli suggested that he or Timo Glock must win a race early this season, but said the venue for the achievement is not important.

"What counts is for it to happen in the first six races," he said.
