Ferrari's New One-Off Is Based on the F8 SpiderFerrari (Ferrari)Buying a car with a Ferrari badge on the nose is already a rather exclusive activity. Buying a Ferrari that the brand has custom-built from the ground up specifically to your tastes is on a whole different level, however. These "One-Off" machines, part of the Special Projects Program, are reserved for the brand’s best (and most well-heeled) customers. Last Friday, the automaker revealed has just completed its newest bespoke supercar known as the HC25, which made its public debut at the Ferrari Racing Days event at Austin’s Circuit of the Americas over the weekend.The HC25 is the latest entry into the brand’s One-Off series, joining projects such as the P540 Superfast Aperta, The F12 TRS, the SP38, the SP48 Unica, and the SC40 from last year. Like all of those machines, the HC25 is based off of a series-production car, but receives an entirely new body designed by the unnamed owner, design boss Flavio Manzoni, and other Ferrari Design Studio staffers.The car itself clearly draws inspiration from some of Ferrari’s recent machines, particularly the range-topping F80. The dual-tone paint setup is quite attractive, with the glossy black band providing a unique visual flair to the car. As with most modern Ferraris, the design language employs a unique mix of soft curves and hard lines to create something distinctly from Maranello. That said, the car is lacking some of the outright beauty of its V-8 predecessors.AdvertisementAdvertisementUnder that shiny new skin sits a F8 Tributo chassis, complete with its twin-turbocharged 3.9-liter V-8 engine and seven-speed dual-clutch gearbox. Ferrari fans may recall that the F8 actually left production back in 2023, but that didn’t seem to be a problem for the factory. The owner specifically wanted a non-hybridized V-8 under the rear decklid, and the F8 is the only “modern” example to forgo any electric assist. Output sits at a claimed 710 hp and 568 lb-ft. The owner’s choice of “base” car also means that this HC25 has a high chance of being Ferrari’s final new V-8 car without hybridization.As you might expect, Ferrari isn’t keen on letting any details about this car’s owner hit the public. That’s understandable, but I imagine we'll ultimately come to learn who commissioned this thing. That is, of course, unless the owner decides that they never want to take the thing out in public.Ferrari (Ferrari)You Might Also LikeIf You Can Only Own One Car, Make It One of TheseThese Are the Most Popular Cars by State
