Plans to build an ultra-limited run of the reborn Lancia Stratos have been killed, with news this week that Ferrari has confirmed it will not support the project.
A green light from Ferrari is vital for production of the Stratos, due to its reliance on the engine and platform of the retired 430 supercar.
Pininfarina, designer and would-be manufacturer of the new Stratos, has also confirmed that it and all other Ferrari suppliers and partners have been ordered to terminate involvement with the project.
"Pininfarina, however, has advised us that they will only carry out construction of a limited run with the express permission of Ferrari," a statement on the New Stratos website reads.
The statement adds that while production of the new Stratos has not been ruled out, the company will need to explore options that do not involve a conflict with Ferrari.
With the Lancia brand owned by Ferrari parent Fiat, the project's founders may find progress difficult.
The news comes as a surprise - or perhaps none at all - after Ferrari president Luca di Montezemolo heaped praise on the prototype car during a test drive at Fiorano.
The only new roadgoing Stratos in existence is owned by German collector Michael Stoschek and was designed and built by Pininfarina. It is built on a shortened version of the Ferrari F430 platform, and uses the 430's 400kW and 500Nm 4.3 litre V8 engine.
