Franz Tost has insisted that Toro Rosso can still 'improve everywhere' despite a solid start to the 2011 F1 season.
The team has scored in six of the nine races run so far, including the last four, and has already bettered the tally it secured through the entire 2010 season.
That means the team currently sits seventh in the constructors' championship, ahead of both Force India and multiple title winners Williams, with the STR6 having proving to be a big step forwards from the car it replaced.
Speaking following the British Grand Prix, where Jaime Alguersuari secured his third top ten finish in a row, Tost said there were a number of reasons why Toro Rosso has taken a step forwards in 2011 but insisted there was still more to come.
“We have new front wings, new rear wings, a new floor, gearbox, diffuser, new exhaust system,” he said. “Everywhere it's a little bit different and all of those factors together resulted in a quite competitive car. The drivers are also making progress and the performance from both has improved during the season. They haven't made major mistakes so they are [finishing] in the points. The team are also growing and increasing their performance.
“We can improve everywhere! If you look to the history of Toro Rosso, we had to start from very nearly zero to build up the team. I'm quite happy with the progress we are making, but we will bring in some more people because we need to strengthen.”
