F1: Toro Rosso's 'first' car debuts in Valencia

Team Toro Rosso finally has a car to call its own as it unveiled the STR5 just  before the first pre-season testing at Circuit Ricardo Tormo in Valencia, Spain.

The STR5 is Toro Rosso's first in-house designed and built F1 car, with the four previous ones all identical to those fielded by sister team, Red Bull Racing. The move to finally design its own car comes from the Fédération Internationale de l'Automobile's regulation, which bans the use of customer cars starting this season. Powering the STR5 is Ferrari's Type 056--the same engine in Ferrari's 2010 car, the F10.

"The STR5 is definitely a case of evolution rather than revolution," said Toro Rosso chief designer Ben Butler. "We have taken a fantastic 2009 package as our starting point and we did not want to do too much with it, apart from changing and adapting it to take into consideration the regulation changes. It is easy to say there is little change between the 2009 and 2010 cars, but there have been a lot of significant evolutions that we have had to put in place, primarily to ensure reliability, and which will hopefully prove to be competitive once the racing starts."

Toro Rosso's driver lineup for the 2010 season is again made up of Sébastien Buemi and Jaime Alguersuari.
