The world champions ended their participation in the four-day Jerez test at lunch time on Friday after completing just 21 laps.
“It’s been a very difficult test,” said team principal Christian Horner. “We have had numerous Renault issues as well as chassis cooling issues, which have affected our progress.”
“However, despite the lack of mileage, what we have managed to learn shows that the problems should be solvable for the next test in Bahrain.”
“Part of the purpose of this early test was to learn about any issues ahead of the start of the season and there will now be a lot of focus on the dyno over the next few weeks.”
Daniel Ricciardo’s run on Friday was curtailed by another technical problem, according to race engineering co-ordinator Andy Damerum.
“We did seven laps and every time Daniel went out we made improvements to the control of the engine. We were also making fixes to the issues that have arisen from our side and we have made progress there.
“However, we then discovered a mechanical issue with the car and after investigation it became clear we would not be able to fix this in time to run in the afternoon, so the decision was taken to retire early, take the data we have amassed and work towards the next test in Bahrain.
“Two weeks is a long time in Formula One and we and I?óÔé¼Ôäóm sure Renault will work flat out now to solve the problems we?óÔé¼Ôäóve been having.”
