Buemi tests Toro Rosso, applauds Buemi's progress

Giancarlo Fisichella was not the only F1 driver in action at the Vairano circuit in Italy last week.

While Ferrari reserve Fisichella was trying Ferrari's updated F-duct solution and the Barcelona package, the other Italian based team Toro Rosso was also conducting an aerodynamic straight line test.

Swiss youngster Sebastien Buemi was at the wheel of the STR5.

"The aim was a bit more long-term, looking at developments for a bit later in the season," he said on Monday.

The media focus in Barcelona this weekend will be more on Jaime Alguersuari, and Buemi applauds the 20-year-old Spaniard's improvement in 2010.

"He has improved a lot and is much faster and therefore able to provide much better feedback," said Buemi. "This is entirely positive, as it means we can work together better to move the car forward."

Team boss Franz Tost is also happy with Alguersuari's progress since he replaced Sebastien Bourdais during last season.

"He discovered how much he had to learn and the level of commitment required to become a successful Formula One driver.

"He was clever enough to understand this and therefore he put himself through a very intensive and disciplined testing and physical training programme and everyone in the team is impressed by his progress," added Tost.
