There's been discussion recently of an updated 599 GTB Fiorano and a replacement for the F430, but the oldest Ferrari in the stable is the 612 Scaglietti. So it would stand to reason that Maranello would be planning to replace the controversial 2+2 flagship before its smaller siblings were updated, and reason may now be affirmed by the latest reports and spy shots emanating from Europe.
This prototype Scaglietti was spied around the factory in Maranello wearing some intriguing bodywork around the front section, suggesting that Ferrari may be testing a new or updated V12 engine for the 612's replacement. With increasing pressure to reduce emissions and improve fuel economy, Ferrari could be working on a more efficient powerplant for the next generation of its largest model.
The current Scaglietti has been on the market essentially unchanged since 2003, and its replacement is tipped to arrive by 2011.
