Toro Rosso's technical upgrades in Hungary in two weeks could amount to nearly a full second per lap in gained time, according to Swiss driver Sebastien Buemi.

Toro Rosso's technical upgrades in Hungary in two weeks could amount to nearly a full second per lap in gained time, according to Swiss driver Sebastien Buemi.

It is already known that the Faenza team will finally fit a double diffuser to its car at the next race.

But it also emerges that the new package will involve most of the recent developments featured on the dominant sister car of Red Bull Racing, including the fatter front nose.

The urgency of the Toro Rosso upgrade is that the Ferrari-powered team has at recent races dropped clearly behind Force India.

Force India's business director Ian Phillips believes Force India has found 1.7 seconds since the beginning of the 2009 season, culminating in Adrian Sutil's impressive seventh grid position with a big load of fuel.

"The modified car brings us nine tenths," rookie Buemi told Germany's Auto Motor und Sport, "and I would be happy if it was only seven."
