Ferrari’s chief technical officer Mattia Binotto has revealed the cause behind the te🍒am’s double engine failure during the Malaysia GP race weekend which came as ‘completely unexpected’ after not showing up during dyno testing.

Sebastian Vettel saw his qualifying at Sepang ended prematurely by an engine issue which forced him to start the Malaysia race from last place, while K♕imi Raikkonen suffered an identical issue with his car during his sighting lap to the starting grid❀ and was forced to miss the start of the race.

Ferrﷺari has run thorough analysis into t𝕴he cause of the double engine failure and Binotto says it was a problem with the inlet manifold on the compressor to the cylinder heads on both cars which was triggered by a defective part.

Ferrari President Sergio Marchionne says changes to the team’🐠s quality department will be enforced to avoid future issues, which Binotto has confirmed in Japan, while explaining the failure only occurred in Malaysia despite the team getting through the entire season, testing and dyno testing without the issue appearing.

“The problem we got was completely unexpected and a problem that we didn’t experience on the dyno or at the track for the entire season,” Binotto said at Suzuka. “There were some quality issue with the parts. We failed with an inlet manifold on the engine from the compressor to the cylinder heads and it ha🀅ppened twice because we had the same problem with Seb in qualifying and Kimi in the race.

“It happened twice in the entire season both in Malaysia so some boun🐻dary conditions have affected the overall reliability which we are analysing but it is something we still need to better understa﷽nd.

“You🌳 can never be fully confident of having solved the problems that we’ve got.”

Binotto has confirmed Marchionne’s comments about t🐲he changes to Ferrari’s quality parts department and hopes the future steps will av💧oid similar failures.

“I think that to improve your performance you need to improve your car pac💖kage overall but you need to also improve your organisation,” he said. “We are considering something which is planned to impr🐻ove the quality department. It is as simple as that.

“Our quality department will be reinforced, that is the part o𝔉f the organisation our chair꧑man was speaking of.”

Ferrari’s Vettel topped the timesheet on Friday practice in Japan two-tenths ahead of Lewis Hamilt💛on in the Mercedes in FP1 after the secꦜond session was a washout.
