Another longtime Ferrari customer is getting a bespoke Prancing Horse made to his liking.

Ferrari's Special Projects division has revealed the latest addition to their one-off creations. This time, it's a front-engined V12 roadster called the SP51.

Designed by the Ferrari Styling Center, the SP51 uses the architecture of the 812 GTS. But unlike the production model it was based on, the latest special project does not have a retractable roof. That means the SP51 was designed with 100% open-top motoring in mind.

When compared to other Ferrari special projects like the SP48 Unica, the Daytona SP3, and the Monza speedsters, the SP51's looks still bear some resemblance to the current Maranello models. If anything, it looks closer to a facelifted 812 that was given a larger grille opening in front.

But still, the exposed carbon fiber elements in the wheel wells and the buttresses give out their unique design characteristics. Not to mention, the Rosso Passionale paint is only exclusive to the SP51.

The same color applies to the Alcantara upholstery inside, together with the 1955 Ferrari 410 S-inspired blue and white stripes that outline the seats and gives contrast in the central tunnel.

While Ferrari did not reveal official figures for the SP51, the one-off is likely to have the same naturally-aspirated 6.5-liter V12 motor as that of the 812 GTS, which produces 800 PS and 718 Nm of torque.

Ferrari says the SP51 is heading to one of their leading collectors based in Taiwan. And while Maranello won't tell how much it costs, it's easily somewhere in the million-dollar range. Definitely more than we can afford.
