Renault tech boss Bob Bell says the French team continued its progress on Tuesday despite its morning programme being hindered by an engine change.
Jolyon Palmer only achieved 15 laps at the start of the day but Nico Hulkenberg enjoyed a consistent period of running in the afternoon.
"Overall, a useful day where we completed most of the tests we wanted to, despite running for fewer laps than originally planned," said Bob bell.
"We did start with a disappointing morning for Jolyon, whose day was disrupted by a precautionary power unit change.
"This gave way to a more positive afternoon for Nico, especially with respectable pace shown on the soft compound tyres.
"Today was another solid step and we’re looking forward to making more progress tomorrow."
Hulkenberg closed his day with the seventh fastest time but more importantly, completed the team's development programme for the day.
"I had a decent run and we were able to complete a pretty much full afternoon programme today," said the German.
"Certainly, you could feel that it was quite windy at times out there and that does affect the feel of the car.
"We gained some further understanding of set-up and tyres and have plenty to consider before we head out again tomorrow."
