Ferrari unveils HC25 one-off roadster

Ferrari unveiled the HC25 on May 15 at the Ferrari Racing Days event at Circuit of the Americas in Austin, Texas, adding another one-off model to its Special Projects program. The car is a roadster built for a single client and based on the F8 Spider’s architecture, chassis and internal-combustion V8 powertrain, Ferrari said. (ferrari.com) The company described the HC25 as a bridge between its earlier mid-rear V8 spiders and newer design themes seen on the F80 and 12Cilindri. (ferrari.com) Ferrari said the car will be displayed during Ferrari Racing Days at COTA. ### Why is Ferrari calling this a one-off rather than a new series model? (ferrari.com) Ferrari said the HC25 comes from its One-Off series within the Special Projects program, which builds unique cars around the requests of a single customer. The company said that places the HC25 in “the most exclusive segment of the range,” with the car sketched and then built to one client’s wishes. Ferrari magazine said the project took about two years and involved design blueprints, a styling buck and multiple verification phases carried out in close collaboration with the client. Ferrari said the work was supported by Ferrari Design Studio under Flavio Manzoni. (ferrari.com) ### What is the HC25 actually based on? Ferrari said the HC25 is derived from the F8 Spider and keeps that model’s layout, chassis and internal-combustion powertrain. The company described it as a “pure, uncompromising roadster” built on the F8 Spider platform. (ferrari.com) Ferrari magazine said the HC25 combines the F8 Spider’s platform and powertrain with a comprehensive redesign of the exterior and interior. Motorionline also reported that the car retains the F8 Spider’s technical base, including the mid-rear V8 layout. (ferrari.com) ### What makes the design different from the F8 Spider underneath? Ferrari said the HC25 was styled to reinterpret the brand’s mid-rear-engined spiders with what it called a “bold, forward-looking perspective.” The company said the body uses a dual-volume structure, with front and rear sections visually linked by a black central band that also incorporates cooling functions, including radiator intakes and heat extraction for the powertrain. (ferrari.com) Ferrari magazine said the black band runs through the side profile and into a redesigned rear screen that exposes the engine, while a long blade milled from solid aluminum integrates the door handles. (ferrari.com) The publication also said the headlamps use a slimmer lens design with modules not previously used on a Ferrari, and that the rear gets slimline taillights set into a full-width graphic. Motorionline said the HC25 is finished in matte Moonlight Grey with yellow accents on Ferrari badges, Brembo brake calipers and seat graphics. Ferrari magazine separately said yellow highlights appear on the brake calipers, shields and interior trim. (ferrari.com) ### What does Ferrari say about the engine and performance? Ferrari said the HC25 uses the F8 Spider’s non-hybrid mid-rear V8 powertrain, but its May 15 corporate announcement did not publish a full technical specification sheet. (ferrari.com) Motorionline reported the car uses a 3.9-liter twin-turbo V8 producing 720 CV, with 770 Nm of torque, a 0-100 km/h time of 2.9 seconds and a top speed of 340 km/h. Other automotive outlets, including Autoevolution and Carscoops, published the same figures after the reveal. (motorionline.com) ### Why was the debut staged in Austin? Ferrari said the HC25 was unveiled at Ferrari Racing Days at Circuit of the Americas in Austin. The company’s announcement tied the debut directly to that client event, and its corporate article said the car will remain on display there. (ferrari.com) Ferrari’s 2026 Corse Clienti calendar page shows the company’s client-track activities as an ongoing part of its owner ecosystem, though the HC25 itself was presented through the Special Projects program rather than as a competition model. (motorionline.com) Ferrari said on May 15 that the HC25 would be shown during Ferrari Racing Days at COTA, and the company has not announced a public production run or price because the car was commissioned for a single owner.
