Ferrari will have a more fuel-efficient engine in 2010, Spain's Diario AS has suggested.

Ferrari will have a more fuel-efficient engine in 2010, Spain's Diario AS has suggested.

To coincide with formula one's ban on refuelling, the sports newspaper said the Maranello based team is working on efficiency improvements allowed under the current engine freeze regulations.

To comply with the test ban, Felipe Massa this week has at Mugello been at the wheel of a two-year-old Ferrari single seater fitted with demonstration tyres.

AS however implied that some "internal solutions" were trialled.

"The test was mainly for him (Massa) and what is certain is that he is even quicker than before his accident of Hungary," said Ferrari development driver Marc Gene.

The Spaniard also sounded confident about Ferrari's 2010 car, which is codenamed 661.

"The wind tunnel data is good and makes us optimistic, but we don't know where the others are so we will have to wait until we see it on the track," added Gene.
