Ferrari team principal Stefano Domenicali believes his team's testing in Mugello this week could make or break their 2012 F1 campaign.
Despite a win for Fernando Alonso at the Malaysian Grand Prix this year, the Italian outfit have continued their poor form of last season, with the likes of Red Bull, McLaren and now Mercedes looking far stronger.
Teams are now in the midst of a break before the season resumes with the Spanish Grand Prix on May 13 and testing is beginning this week in Mugello, Italy.
Domenicali has been fully aware of the limitations of the F2012 in the current season, with both Alonso and Felipe Massa struggling for pace compared to their rivals.
However, the Ferrari boss believes the team will be determined to make improvements in testing this week on the Mugello circuit.
"The coming days will be important. The main objective is to push hard on the development of the car," he said.
"(It's) clear that we must step up a gear, right from the next race".
