Renault is hoping for the best ahead of this weekends race.
Mar.14 (GMM) Renault is giving its F1 customers full power in Australia.
The French marque is still grappling to solve the serious problems encountered during the winter test sessions, where the new Viry-made turbo V6s were 'turned down'.
"We did not have the necessary experience with well-functioning software," said Renault's Remi Taffin, "so we had to be careful, limiting the engine power.
"But now I'm not worried about it," he is quoted in Melbourne by Russia's f1news.ru.
"We have done a huge amount of work, we feel a lot more confident here and our customers will be able to use the engine to maximum capacity," added Taffin.
"Progress has been made, but we will not rest until we are winning races again."
