Renault says that improvements must be made to their power units if they are to achieve good results in 2014.
Renault endured a difficult pre-season campaign but matters improved in Australia. Nonetheless, head of track operations Remi Taffin acknowledges that Renault must allow their four customer teams to prove their worth at the Malaysian Grand Prix.
"There are definitely mixed feelings," he said.
"Having cars retire is not acceptable and shows we need to improve our reliability across the board. This race was always going to be a baptism of fire but we have come short of our own expectations and we need to look at this before the next race. Some failures are similar, such as the MGU-K on the Lotus, but others are not related, which shows that we have to improve across the board.
"This is something we will look keenly at before the Malaysian Grand Prix to allow every team the chance to show the maximum potential of their cars. However the other cars performed very well and we are pleased with the achievements."

Renault power was used by eight cars at the Australian Grand Prix and only three of them made it to the finish, however Daniel Ricciardo was later disqualified due to exceeding the fuel flow limit, something which Red Bull will contend.
Renault's two classified finishers were the Toro Rosso duo of Jean-Eric Vergne and Daniil Kvyat, who collected eighth and ninth place respectively.
World champion Sebastian Vettel retired after only a handful of laps after a misfire on the power unit caused a loss of power. The German driver also encountered similar woes during qualifying.
Both Lotus drivers retired in the race due to an MGU-K failure, with Romain Grosjean lasting 16 laps longer than Pastor Maldonado.
Kamui Kobayashi crashed out on the first lap after an electrical problem with his brakes that had developed on the formation lap. Marcus Ericsson retired the sister Caterham due to a drop in oil pressure.
