Toro Rosso have a hard act to follow in 2009 - Tost

Toro Rosso presented their new STR4 Formula One car yesterday with team boss Franz Tost recognising they would struggle to live up to last year's race-winning performance.

"All race teams should have the same targets: to win every race they enter," he said before France's Sebastien Bourdais completed the first laps in testing at Barcelona's Circuit de Catalunya.

"Of course, this is not going to happen and even matching our 2008 showing will be difficult, as the sport enters a new era.

"Therefore, our target has to be to leave every race track on a Sunday night knowing we have done the best job we could."

Germany's Sebastian Vettel produced a major upset when he won the team's home Italian Grand Prix from pole position at Monza last September to become Formula One's youngest race winner at the age of 21.

Toro Rosso also scored 39 points, more than ever before, and finished sixth overall and one place ahead of sister team Red Bull.

Vettel has since moved to Red Bull, with 20-year-old Swiss Sebastien Buemi replacing him as the sport's sole rookie and youngest driver on the starting grid when the season starts in Australia on March 29.

Bourdais, whose career had hung in the balance until February, is retained for a second season after a difficult debut.

Toro Rosso's car is designed by the Adrian Newey-led Red Bull Technology, but differs from the Red Bull in having a Ferrari engine and KERS energy recovery system rather than the other team's Renault package.

Technical director Giorgio Ascanelli, whose team have to design their own chassis from next year under the current rules, said the car already had very different systems to the Red Bull.

While the bigger teams have shed staff since last season, with cost-cutting measures including a ban on testing and a need for far fewer engines, Tost said Toro Rosso had bucked the trend.

"The team is bigger, having expanded its facility in Faenza and we have taken on more staff," he said, adding that test team members had been allocated other roles.
