The video posted here shows a LaFerrari supercar lapping the Fiorano circuit in Maranello amid the distinct tones of a turbo engine.
That Ferrari road car, however, is usually equipped with a normally-aspirated V12 engine. The car seen in the video is clearly a turbo unit.
Auto123.com got in touch with a Formula 1 technical expert to know if that could really be Ferrari's new F1 power unit.
"I've not heard any real confirmation either way, but I seriously doubt that it's the F1 turbo engine," he replied.
"I wouldn't expect Ferrari to advertise the fact they are running the V6 power unit, especially in such a scruffy looking test car," he added.
The test was most probably about a street car engine, or endurance race car motor.
