Stefano Domenicali has revealed that Ferrari will launch an investigation into their poor race-pace in the Hungarian GP.
Although Sunday afternoons have been Ferrari's strong point this season where Fernando Alonso and Felipe Massa were able to make up ground after Saturday's struggles, the same could not be said of the Hungarian GP.
The Budapest race, though, was the first time that the revised Pirelli tyres had been raced, prompting concerns about how the F138 is handling the changes.
"We have seen that we have lost the gap that we had at the first few races," Domenicali told Autosport.
"During the races, the pace was clearly very strong; now in the conditions here [in Hungary] we have seen that we are not where we wanted to be on both tyres - soft and medium.
"We need to understand if this is the case [that the new tyres hurt Ferrari] and how to react, because this will be the structure of tyres we have until the end of the season.
"Then a lot will depend on the choice of compounds for the races at the end of the season. It is something we need to analyse carefully - as it seems Mercedes has solved the issue that it was suffering massively in the races."
The team boss added that he expects better at the next grand prix in Belgium with the hope that Ferrari will be strong in both qualifying and the race.
"After the very good race from the performance point in Germany and Silverstone, we have improved the car for qualifying - but we haven't for the race.
"We have done a programme to be ready for Spa, and hopefully we are able to manage it.
"There is no reason to be feeling negative pressure. I am expecting a reaction from my technical group and this is what matters."
