Italiaspeed, the shots were taken back in June at Alfa Romeo's Balocco test track in Italy. But exactly what it is, nobody seems quite sure.
Rally fans, Lancisti and those with good memories may remember the Fenomenon Stratos concept from the 2005 Geneva motor show (bottom right), and this seems to be the best bet for the original source of the new car, although the nose appears to have been mildly redesigned.
As for the drivetrain and chassis, the situation is as clear as the fuzzy spy shots. The general consensus seems to be that the Stratos will use a Ferrari V8 and a chopped-down Ferrari chassis, though whether these will come from a 360 Challenge Stradale, an F430 or even an F430 Challenge racer is unclear.
On the other hand, these could just be the first images of an Alfa 8C-style halo car for Lancia. Here's hoping...
