Gabriele Tarquini took the wheel for the majority of the time before Tiago Monteiro replaced him on Tuesday afternoon.
Team Principal Alessandro Mariani commented: “It was a very good test. We were able to go through the full programme we had planned without meeting with the lesser technical issue.
"The track is excellent for testing as it offers both fast and slow corners. So we had the opportunity to work on the engine and the chassis set-up, and we also completed some long runs.
"We are very satisfied with the outcome. The performance is there, especially in terms of race pace. During the previous test at Vallelunga, we sensed the potential of the car; at the Slovakia Ring we have had the confirmation that this potential is really promising.”
Tarquini echoed: “The Civic is a very good racing car to work on. We have tried some different set up, testing its reaction. The results were encouraging.
"Our relationship with the Civic has just begun and I think we have only unveiled 25/30 per cent of its potential.
"Performance is already there, so we are optimist. However we still have a long work to do and we must wait until we measure ourselves with the competitors.”
