Ferrari SP51 is a V12 roadster with gorgeous paint based on the 812 GTS Spider

Ferrari says it spends an average of two years on its one-off Special Project cars such as the SP48 Unica from earlier this year, which was based on the F8 Tributo. Here’s another before the year is out, the SP51 that rides on the bones of the 812 GTS convertible. A Taiwan-based client and collector had the idea and the funds to make it happen, working with the Ferrari Styling Center on a highly advanced and proper roofless roadster that nods to historical Ferrari roadsters as well. A reshaped front fascia houses a black, carbon fiber insert below smaller headlights. Another large section of exposed carbon fiber piece below the windshield reaches forward to the hood vents, framing the center of the hood. Along the flanks, the 812’s upswept sculpting is redirected, scalloped sides rising gently to the middle of the door then descending toward the rear wheels. Above that, a pair of flying-buttress-like cowls help shape the dark lines of rear intakes behind the cabin. A carbon fiber wing runs across the car above the cowls, concealing the roll hoops.

A custom set of rims are set off by carbon fiber wing profiles in the front fenders. In back, the quad taillights peek out from below the decklid spoiler and above the deep, layered diffuser. Ferrari said it took a heap of “CFD simulations, wind tunnel and dynamic testing” in order to imbue the “ultimate in comfort in the cabin, but also the same standard of acoustic comfort and wind feel as the car that inspired it.”

That color seen outside and in is Rosso Passionale, a custom hue applied in three layers. The blue and white stripes running over the body and through the cabin pay tribute to the blue and white livery inspired by a 1955 Ferrari 410 S, an early race car powered by a 5.0-liter V12. A 410 S with chassis number 0592CM shows off that paint scheme, the roadster driven by Carroll Shelby to wins in Palm Springs the year it was delivered to owner Tony Parravano.

The cabin continues the blue and red theme, with Rosso Passionale offset by blue striping and white cross stitching on the instrument panel lower, seats, center tunnel, and doors. It can’t be bought so the price doesn’t matter, making the only real question: Would you have this, or the Ferrari Special Projects roadster from 2014, the F12 TRS?
