Ferrari’s chief technical officer Mattia Binotto has revealed the cau𓆏se behind the t🌟eam’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 Kimiဣ 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.

Ferrari has run thorough analysis into the cause of the double engine failu🌸re 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 say♛s 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 seꦕason, 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 compress♚or to the cylinder heads and it happened twice because we had the same problem with Seb in qualifying and Kimi in the race.

“It happened twice in the entir꧅e season both in Malaysia so some boundary conditions have affected the overall reliability which we are analysing but it is something we still need to better understand.

“You ca🍃n never be fully confident of having solved the problems that🀅 we’ve got.”

Binotto has confi𒉰rmed Marchionne’s comments about the changes to༒ Ferrari’s quality parts department and hopes the future steps will avoid similar failures.

“I think that to improve your performance you need to improve your car package ov༒erall but you need to also improve your organisation,” he said. “We are considering somet♔hing which is planned to improve the quality department. It is as simple as that.

“Our quality department will be reinforced, that is the part of the orga𒁃nisation our chairman was speaking of.”

Ferrari’s Vet⭕tel topped the timesheet on Friday practice in Japan two-tenths ahead of Lewis Hamilton in the Mercedes in FP1 after the second session was a washout.
