Nineteen units. That is the entire production run for the Eccentrica V12 Roadster, a roofless rework of the Lamborghini Diablo that the small Italian outfit plans to reveal at The Quail on August 14 during Monterey Car Week.
Eccentrica launched its fixed-roof V12 restomod back in 2024, taking early Diablos and rebuilding them with modern engineering underneath period-correct attitude. The Roadster follows the same playbook but loses the top, exposing a cabin that Eccentrica says retains the coupe’s 208-mph top speed despite the aerodynamic penalty.
Powering the thing is a naturally aspirated 5.7-liter V-12, untouched by turbochargers, producing 550 horsepower at 7,000 rpm and 443 pound-feet of torque. A six-speed gated manual sends that power rearward, though eagle-eyed observers have noticed the company’s own renders only show five speeds on the gate. Nobody at Eccentrica has addressed the discrepancy.
The company claims more than 3,500 new components distinguish its cars from donor Diablos. Body panels are carbon fiber, the chassis is a carbon-reinforced steel frame, and new splitters, a reshaped rear wing, and lighter wheels round out the aero and unsprung-weight improvements. The ECU has been remapped for sharper throttle response, which in a car with no roof and a screaming V-12 behind your head should be its own form of therapy.
Eccentrica describes the Roadster as having “90s soul and modern precision.” That is a polished way of saying they took one of the most difficult, dangerous, and thrilling supercars ever built and tried to sand down its sharper edges without killing the character. Whether they succeeded depends entirely on which of the 19 future owners you ask.
No price has been announced. Given the exclusivity, the donor-car acquisition costs, and the sheer volume of bespoke engineering involved, the number will be something Eccentrica shares only with buyers who don’t need to ask. The Diablo restomod market exists in a rarefied space where the car’s cost is almost beside the point. What matters is the story, the theater, and whether the machine delivers the visceral hit that a stock Diablo promised but often punished you for seeking.
Monterey Car Week has become the annual debutante ball for exactly this kind of car. Ultra-low-volume builders like Eccentrica, Singer, and others roll into the peninsula every August armed with hand-built machines aimed squarely at collectors who already own everything else. The formula is consistent: take a beloved icon, rebuild it with contemporary materials and calibration, keep the analog soul, and charge accordingly.
The Diablo is a smart base for this treatment. It occupies a strange place in Lamborghini history, overshadowed by the Countach before it and the Murcielago after. But for a certain generation of enthusiasts, the Diablo was the bedroom-wall poster. Raw, wide, loud, and slightly terrifying, it was everything a supercar was supposed to be before electronics started doing the thinking.
Eccentrica is betting that 19 buyers feel the same way. Whether the Roadster lives up to the original car’s reputation or merely dresses in its clothes will become clear once keys start turning later this year.
