FIA approves Ferrari engine changes
A statement by Ferrari said: "A lot of work was carried out on the test bench, completing several long runs and this work produced some solutions which it is felt will solve the reliability problems experienced in Bahrain and Malaysia. The team therefore requested and received authorization from the FIA to make some changes within the framework of the current engine regulations and these modifications will be fitted to the engines to be used in Spain.
"While since China, everyone in the Gestione Sportiva has been working hard as always on their various areas of activity, it is fair to say that over the past weeks, the staff in the engine department really produced a major effort, working night and day to analyze, evaluate and solve issues that have affected engine performance in past races."
