Don’t be too alarmed if you haven’t heard of the Eccentrica V12 Roadster. Even elite car trivia buffs may have missed this one, although you might know it by its former identity. The new restomod started life as a Lamborghini Diablo Roadster, but has undergone a boutique reinvention at the hands of the San Marino-based outfit.

The Roadster joins a range of past builds that started with the unveiling of the V12 coupe in 2024, which used a closed-roof Diablo as its starting point. More than just an aesthetic overhaul, the V12 Roadster reworks the Lamborghini 5.7-litre V12 engine with a remapped ECU, re-engineered airflow and cooling, sharper throttle response and 410kW of power at 7000rpm, up from around 362kW in its original guise.

Crucially, the Diablo’s gated six-speed manual remains, with analogue interactions at the heart of the driver interface. Acceleration from 0-100km/h takes a claimed 3.8 seconds, with a top speed of 335km/h.

Far more noticeable, though, is the V12 Roadster’s modern restyle. The unmissable and iconic silhouette of the Diablo remains as a starting point, but lines have been sharpened, details finessed, and every aspect of the original design obsessively reworked to look both instantly recognisable and more modern.

The new body, crafted in carbon fibre, cloaks a range of performance-oriented upgrades like hydraulic power steering, hand-tuned semi-adaptive suspension, 380mm front and 345mm rear brakes with Brembo calipers, and a carbon-fibre-reinforced steel spaceframe chassis.

The interior features digital instruments, Connolly leather, Alcantara, and exposed carbon-fibre elements. Each V12 Roadster is configured to its owner’s specifications, ensuring no two cars from the planned run of 19 units are the same. Eccentrica’s conversion process used 3540 new components, with everything from LED lighting to the interior layout overhauled in the process.

As for pricing, Eccentrica hasn’t offered any clues yet, but with the coupe version starting at around €1.2 million (A$1.96 million) on top of the price of a suitable donor car, expect something similar, if not higher, for the Roadster.
