Ferrari driver Felipe Massa believes the new F2012 car must be tested to the fullest extent possible ahead of the Formula One season.
Massa's team-mate Fernando Alonso set the fastest time on the final day of pre-season testing in Jerez earlier this month, but the Spaniard also completed the fewest laps of any driver present.
Italian team Ferrari have another opportunity to put the new car through its paces during a second testing session, which is set to take place in Barcelona during the week ahead.
"I've been able to try the car on the Catalunya Circuit, at least on the simulator," Massa said.
"The past two days have been very interesting, because we ran both on the track where the new car has already run, in other words Jerez, and then on the next circuit."
"There's a lot of work to do to finetune the F2012 but, as both Fernando and I said last week, I think this car has plenty of potential."
"It will be important to do a lot of kilometres next week, because we have many ideas we want to try out and it's essential we don't have any problems."
"I know that on this front too, the team has worked assiduously to ensure that me and Fernando can do a lot of laps."
Massa said Ferrari will not be looking closely at their lap times throughout the Barcelona run-out.
The Brazilian wants to wait until the first race of the season, the Australian Grand Prix on March 18, to see how his team measure up against the rest of the competition.
"I'll say it before we even start: again this coming session, we won't be looking at the stopwatch, especially as you can never know what your rivals are running," he said.
"The truth will only begin to emerge in Melbourne."
