Ferrari test driver Pedro de la Rosa says that his time in the F138 on the final day of testing in Jerez will help improve the Scuderia's simulator.
De la Rosa completed 51 laps of the Spanish circuit, with his morning disrupted by a gearbox failure.
"All in all it's been a positive day for me, I finally got a feel for the car and that will be very important when it comes to comparing the data with the simulator as we develop the car," he said.
De la Rosa, who spent several years as McLaren's test driver, hinted that Ferrari has catching up to do compared to his former team.
"We are not yet where we want to be on our simulation and there will be a lot of work to do, but that's why I've been taken on and in my own small way I hope to do my best to contribute to the progress of the Scuderia."
The Spaniard stopped on track on his second lap and admitted it was dispiriting for his début to end so quickly, but thanked the team for fixing his F138.
"I had a lot of mixed feelings today: I was very excited to drive the car but when I got out after the first two laps I was not exactly happy."
"All my life I've been waiting for an opportunity like this and to see it end after just a few corners was definitely not nice, especially because I wasn't sure that we would be able to continue with the programme. But then the team did an amazing job and it was vital to get back on track given how few days are available to us."
