Designer Nikolas Tombazis has revealed that next year's Ferrari will be very different to the current single seater.
The Italian team recently split with technical director Aldo Costa, admitting Ferrari needs to be more aggressive in order to start championship campaigns on terms with its rivals.
For 2012, Greek designer Tombazis has revealed that "many areas of the car will change.
"The change will be greater than in other years," he is quoted by Spain's AS newspaper.
Tombazis is also quoted as saying by Brazil's Globo Esporte: "I think honestly next year's car will be neither an evolution from this year or a total change."
But a difficulty for teams at this point of the season, particularly with Red Bull so far ahead in the championships, is how to split the resources between the two car projects.
Some resources should be used for this year's car because we want to win some more races
A further complication is that a major development area in 2011 is the blown exhaust, which will not be allowed next season.
"Some resources should be used for this year's car because we want to win some more races," said Tombazis. "Obviously some things do not apply to next year's car, but some do.
"So we need to address this, trying to prioritise our resources for the two cars."
