Lamborghini Fenomeno Roadster debuts as the most powerful Open-Top from the brand

Key Highlights

• Lamborghini has unveiled the Fenomeno Roadster at the Lamborghini Arena in Imola.
• Just 15 units will be built.
• Combined system output is 1080 CV from a 6.5-litre naturally aspirated V12 and three electric motors. It is Lamborghini’s first V12 hybrid open two-seater.

Fifteen units. 1080 CV. No roof. That is the Lamborghini Fenomeno Roadster in three lines, and it is already the most powerful open-top car the brand has ever produced.

Unveiled at the second edition of the Lamborghini Arena event in Imola, the Fenomeno Roadster is the convertible evolution of the Fenomeno Coupe revealed in 2025. It sits within Lamborghini’s Few-Off programme, a lineage that includes the Reventon, Veneno, Centenario, and Sian, all offered in both Coupe and Roadster form. The Fenomeno Roadster continues that tradition, and raises the bar considerably.

Powertrain

The heart of the Fenomeno Roadster is a 6.5-litre naturally aspirated V12 producing 835 CV at 9,250 rpm and 725 Nm at 6,750 rpm. Lamborghini calls it the most powerful V12 the brand has ever built, with a specific output exceeding 128 CV per litre. Three electric motors join the equation, two at the front axle and one above the 8-speed dual-clutch gearbox, handling torque vectoring and regenerative braking. A 7 kWh lithium-ion battery enables a fully electric mode.

Construction and Design

The chassis uses a full carbon fibre monocoque with a front structure in Lamborghini’s patented Forged Composite material, the same aerospace-inspired monofuselage architecture used in the Revuelto. Despite losing the roof, the Roadster achieves near-identical stiffness to the Coupe with only a marginal weight increase.

The hexagon is the recurring design signature throughout, appearing in the lights, air intakes, exhaust outlets, engine cover, and cockpit. The car is presented in Blu Cepheus with Rosso Mars accents, a tribute to the colours of Bologna. Brakes are the CCM-R Plus carbon-ceramic system. Tyres are custom Bridgestone Potenza Sport units in 265/30 ZRF21 front and 355/25 ZRF22 rear.

All 15 units are already spoken for. This one was never going to sit in a showroom.
