Driving without traction control, Adrian Sutil did not betray any signs of discomfort as the driver made the most of the sunny conditions to complete just under 400 kms on Force India's productive second day of testing here.
In clear conditions, the German driver made up for Day one's limited running, with the scheduled work on dampers and set-up going ahead without any major mechanical problems.
The German completed 98 laps of the Spanish track, with his best lap - a 1 min 13.4 - closer to the pace than Day one's Force India time.
Sutil would now pave way for Giancarlo Fisichella to take over and bring Force India's second test of the season to a close.
Elated with the way thing progressed on day two, Sutil said, "We had quite a good day today, completing nearly 100 laps. We were able to do quite a few runs in the afternoon and the times were pretty OK and the balance, as usual, was good and getting better.
"I'm now back feeling much more comfortable after a long break over Christmas and I'm much more used to driving without traction control," he said.
"We're tweaking the settings all the time and getting closer to the edge," Sutil added.
Chief technical officer Mike Gascoyne too was happy after what he felt was a fruitful day.
"We completed our programme of damper and set-up work and further development of the ECU and had a useful day with no reliability issues," he said.
