The Dutch rookie propped up the time sheets and also stopped on track with fifteen minutes left.
"We've had a pretty productive day and completing 93 laps meant we were able to run through the whole plan we'd set out for today," he said.
"We had a technical issue in the afternoon which meant we were running without KERS for the whole session after lunch but despite that we were still able to try a number of different setups that give us more to work on tomorrow and several options to work through at the next test".
"One area we are focusing on is improving the rear stability of the car. It definitely has a sharper front end than the 2012 car but we need to take a more detailed look at that tonight and, assuming the rain stays away tomorrow, we can keep working on that on day four of this test."
