Just a day after Scuderia Toro Rosso fired its French driver Sebastien Bourdais after a lacklustre season and a half and with the team's hopes high as a significant aero update is due at the forthcoming Hungarian Grand Prix, Team Principal Franz Tost and Technical Director Giorgio Ascanelli have today answered questions in a statement.

Toro Rosso had quite a successful start to the season, scoring points in Australia and China and later, in Monaco, we picked up another one. However, from then on, we lost touch with the other mid-field runners. There are various reasons for this: firstly, the other teams improved their cars, regularly producing updates to their technical package. We introduced a few small updates, but nothing major. For example, we are the only team never to have run with a double diffuser, one of the key elements to car performance this year. Why? It was a financial decision. Rather than incur the costs of constant updates, we chose to keep costs within budget by waiting, before delivering one major update package, which will make its race debut at the Hungarian Grand Prix. Secondly, apart from the limitations on car development, we also had one driver who did not live up to our expectations.

We expect that the technical upgrades should see us return to a level of competitiveness that we were able to demonstrate in the second half of last season.

Buemi has done a really good job so far. You have to consider that, as the only rookie on the grid this year, he is the first real victim of the in-season testing ban. He had therefore never driven at circuits like Silverstone or the Nürburgring in a Formula 1 car, which is completely different to tackling them in other types of car. While he knows the tracks from Formula 3 or GP2, it is not at all the same, because F1 is much more complex and little details like how track conditions usually change from the third free practice session on Saturday morning, to qualifying that same afternoon, are all part of the package that only comes with experience. Up until this year, we would have done a minimum of three days testing at Silverstone for example, prior to the British Grand Prix and at many other race venues. But you can’t have everything and while we are saving money through not testing, the downside is that young drivers will suffer. What we can say is that Buemi will be a much more complete driver for the 2010 season.

There are several factors why our performance hasn’t matched up to what it was in the second half of last season. The first is that the drivers are very important and last year, Vettel matured enormously, getting over the difficult phase every young driver does, not understanding why he was fast or slow. A second factor was that last year, within the limits of our own capabilities, we went down a different route to Red Bull Racing, particularly with suspension and the braking system that was different to their car. The third point is that last year we were racing in an era where the technical rules had been more or less stable for a decade so performance levels flatten out, making it harder to come up with something new. This year, the pace of development has speeded up enormously and as a small team, we have been unable to keep up with that. Today, Red Bull for example is producing large steps forward in development on a monthly basis. We cannot do that as we don’t have the manpower. Furthermore, with a young and inexperienced driver like Buemi, when we do introduce changes, it is naturally harder for him to adapt to those changes.

Absolutely not: to date, he has taken part in just nine grands prix and in four of those he retired early. Add in the fact there is no testing and he is getting very little time in the car. When a young driver first comes into F1, he is like a daredevil, taking risks, but as his understanding increases and he suffers a few set backs, it knocks his confidence which then has to be rebuilt. We cannot expect him to learn any faster: he is trying his best and doing a good job. Remember that when Vettel came to us, he had done one year as a third driver for BMW and had even taken part in one Grand Prix, but he could do no better than qualify eighteenth for us in his first race, in Hungary.

In Hungary we have a major upgrade, which includes the floor, rear wing, rear wing endplates, a nose which has had to pass a new impact test, new brake ducts etc. – pretty much the whole damn lot! We’ve worked our hardest to get this modification package and to do it this year is much harder than the work we did last year.

There is a view that the only difference between our car and the Red Bull Racing one is the engine, but that is inaccurate. It involves the engine, gearbox, clutch, hydraulic system, water, oil and electrical systems; and all this on top of the actual aero parts in terms of bodywork. The further complication is that, although we have not run it, our car was designed so that it could incorporate the Ferrari KERS system and that is very different to the one used by Renault, around which the RB5 was designed. Therefore, we are not in a “cut and paste” situation when it came to getting the parts. It was not a case of getting a drawing from Red Bull Technology and simply manufacturing it. The two cars might look the same but if you try and fit the bodywork from one on the other, it would not fit. The rear suspension is also different because, in order to maintain the same wheelbase, it needed a different arrangement.

I will tell you once we’ve run it at the race track.

It would be a package equivalent to the one they introduced at the British Grand Prix.
