Engine manufacturer Renault is confident that its power units will be ready for the next month's Australian Grand Prix, despite struggling during the first two pre-season tests.
All four Formula One teams that make use of the French manufacturer's engines have struggled during pre-season, but Renault head of track operations Remi Taffin is positive that they will be able to deliver a strong product by the time the season starts in Australia in little more than a fortnight's time.
"There is still room to play with and we hope to have everything working together at maximum performance when we get to Melbourne," Taffin told Autosport.
"I think we will be ready to run [at the Australian GP], but it depends what performance we will get there.
"We have a programme to do [before then] and if we do it maybe we have a chance to do well over there.
"If you look where we were three weeks ago and where we are now; if we make the same step to Melbourne I will be happy."
Despite the struggles of Red Bull, Toro Rosso, Lotus and Caterham in Bahrain last week, Taffin believes Renault's major problems are behind them now.
"The major ones are now behind us, so we can start building up programmes and try many items," he added.
"Many are fixed, but we still see a few.
"We are now far from having all the issues we had before.
"We are making progress. We are now in a position to tick every box on the list. "We have good support from our factory and our teams, and we are all working together.
"When the problems are fixed - and we are close to fixing them - then we can move on."
