The French manufacturer said prior to the 2014 season opener in Australia that its recovery plan was “on course” after a difficult 12 days of pre-season testing in Spain and Bahrain. However, of the five Renault-powered cars that retired from the 57-lap race, four were caused by problems with the power-unit.
Sebastian Vettel was the most high-profile driver to exit the race after a problem on lap four. The Lotus duo of Pastor Maldonado and Romain Grosjean both suffered MGU-K issues and Marcus Ericsson retired from his first F1 race after an oil pressure problem.
Rémi Taffin, head of track operations at Renault, is confident that most of the issues are now solved, although he admits that further problems are anticipated.
“After a difficult race in Australia we are really looking forward to Malaysia,” he said. “We had several issues across the cars in Melbourne but we have recreated the problems in the dyno at Viry.
“Most are fixed and the remaining will be under control by Friday in Sepang. While we anticipate further issues may occur we are much more able to react quickly to minimize their impact.”
He expects the Malaysian Grand Prix to become one of the hardest tests on the calendar for F1 engines due to this year’s regulation changes.
