Ferrari Tests Mysterious Turbocharged LaFerrari Prototype

Over the last few months, Ferrari has been caught testing mysterious prototypes based on theLaFerrari. Initially, it looked like Ferrari was testing mules for the LaFerrari's replacement, but it's now believed they were test mules for thenew Icona supercar debuting next month.

A successor to the Ferrari SP1 and SP2 Monza, Ferrari's new ultra-exclusive Icona will reportedly be based on the LaFerrari Aperta restyled as a homage to the 1967 Ferrari 330 P4 Le Mans racer. One month before the reveal, Ferrari has been caught testing another LaFerrari prototype.

Video footage shows the matte black LaFerrari cruising the streets. However, this doesn't appear to be a test mule for the new Icona. Ferrari's 330 P4 tribute has already been spied withproduction parts covered up, but this prototype is uncovered. What could Ferrari be cooking up here?

Compared to the regular LaFerrari, the prototype has several key design changes. There's a new bumper without the central element separating the grilles, while the side air intakes, roof and rear window look different. Whereas the LaFerrari uses center-lock wheels, this test mule has five nuts per wheel. But the most obvious change lies under the hood.
