Nineteen cars. No roof. Two hundred and eight miles per hour. Eccentrica is bringing its Diablo-based V12 restomod to Monterey Car Week in open-top form, and the Swiss builder is making no apologies for the physics involved. The V12 Roadster debuts at The Quail on August 14 — and represents something the factory never attempted: a roofless Diablo, rebuilt from the ground up for people who find consequence thrilling rather than inconvenient.
Engineering the Open Air
Stripping the roof from a 208-mph car required more than a hacksaw and optimism.
Eccentrica says the Roadster involved more than 3,500 new or bespoke components, a carbon-reinforced steel frame, and carbon fiber body panels. Removing the roof triggered a separate aerodynamic development program, plus suspension revisions and structural reinforcement to restore rigidity.
The powertrain stays honest: a naturally aspirated 5.7-liter V12 producing 550 horsepower and 443 pound-feet of torque, routed through a six-speed gated manual. Eccentrica confirms the six-speed gated manual as the production specification; render details remain subject to final build. Zero to 60 takes roughly 3.8 seconds, and top speed, Eccentrica claims, still hits 208 mph. Hardware updates include:
- A widened track
- Revised suspension geometry
- Semi-active dampers
- Brembo brakes
- Lighter wheels
The cabin reads like a bespoke tailor’s invoice: Connolly leather, Alcantara, anodized trim, carbon fiber left deliberately visible. Nothing here is catalogue.
Founder Emanuel Colombini describes the Roadster as “more exposed, more immediate, more demanding” — a precise way of saying that wind, noise, and consequence arrive together at speed. That’s not a flaw. It is the entire argument for building this car in 2025. Vinyl came back because some things are worth the friction. A naturally aspirated, manual-gearbox, open-top V12 is exactly that kind of friction — analogue and demanding, at a moment when most performance cars are moving in the opposite direction.
19 Cars. One Reveal. No Price.
Scarcity this deliberate stops being a marketing strategy and becomes a philosophy.
Production caps at 19 units, each configured individually per customer. Pricing remains unannounced, though the earlier coupe started around €1.2 million — approximately $1.3 million — before the cost of a donor car. The Roadster will carry a higher price; the degree of that premium is not yet public. The ultra-rare convertible supercar space is crowded with ambition but short on follow-through.
The Quail on August 14 is where Monterey Car Week’s most concentrated audience of collectors and enthusiasts gathers, and Eccentrica’s positioning speaks directly to them: “An icon with ’90s soul and modern precision.” That framing holds when the car behind it is one of the few places on earth still building a manual V12 open-top from the ground up.
Nineteen people will own this. The rest of the world will watch renders and footage, imagining what hot aluminum and Connolly leather smell like at 150 mph with nothing above their heads. For those 19, that question has a very expensive, very real answer.
