Lamborghini Fenomeno Roadster Is The Most Powerful Open-Top Raging Bull Ever - Limited To 15 Units

Lamborghini has unveiled the Fenomeno Roadster, an open-top evolution of the Fenomeno Coupe first shown in 2025. Revealed at the second edition of the Lamborghini Arena, the Lamborghini Fenomeno Roadster is the most powerful open-top car the brand has ever built. Production is capped at 15 units, each built to individual specification.

The Fenomeno Roadster sits within Lamborghini's Few-Off programme, a lineage that includes the Reventon Roadster (2009), Veneno (2013), Centenario (2016) and Sian (2019). Like its predecessors, the car serves as a testbed for design and engineering solutions that could make their way to future production models.

Lamborghini Fenomeno Roadster - Chassis & Structure

The Fenomeno Roadster's carbon fibre monocoque uses the same aerospace-inspired monofuselage architecture as the Revuelto. The front structure is built from Forged Composite, integrating crash structures, windshield frame, rear bulkhead and side sills into a single lightweight assembly.

Removing the roof on the Fenomeno Roadster added only a few kilograms over the Coupe. Lamborghini achieved this through a patented combination of long and short carbon fibres with a fluid bonding mixture, a technology used here for the first time in a hybrid configuration on a production Lamborghini.

Lamborghini Fenomeno Roadster - Aerodynamics and Design

The Fenomeno Roadster's aero package is entirely new compared to the Coupe. A carbon spoiler above the flat windscreen channels air into the open engine bay, ensuring V12 cooling even without the Coupe's roof-mounted air scoop. Combined with a revised rear clamshell, the car matches the Coupe for downforce, stability and brake cooling.

The rollover bars are integrated flush behind the sports seats and blend into sculpted Speedster humps. Lamborghini engineered them to be aerodynamically efficient at top speed while meeting safety requirements. The result is a flat, uninterrupted silhouette with a clear centreline and sharply defined flanks.

The hexagonal design motif runs throughout the Lamborghini Fenomeno Roadster: side skirts, wheel arches, air intakes, LED light signatures and the high-mounted hexagonal exhaust. The show car wears Blu Cepheus over Rosso Mars, a two-tone combination chosen as a tribute to the city of Bologna, and a visual reference to the 1968 Miura Roadster.

Lamborghini Fenomeno Roadster - Cockpit

The interior of the Fenomeno Roadster is built around carbon fibre, Dinamica-based Corsatex fabric and Lamborghini's patented Carbon Skin material across the dashboard, seats and door cards.

Three digital displays with hexagonal graphics combine with haptic buttons and aviation-style switches in a layout Lamborghini calls Pilot Interaction. Contoured seats with red contrast stitching hold occupants in place through high-G cornering loads.

Lamborghini Fenomeno Roadster - Hybrid Powertrain & Performance

The Fenomeno Roadster's 6.5-litre naturally aspirated V12 produces 824bhp at 9,250rpm and 725Nm at 6,750rpm, giving a specific output of over 126bhp/litre. That's t/e highest figure ever achieved by a Lamborghini V12. Three electric motors, two at the front axle and one within the eight-speed dual-clutch gearbox, bring the combined system output to 1,065bhp.

The 7kWh lithium-ion battery supports torque vectoring, regenerative braking and a fully electric driving mode. The Lamborghini Fenomeno Roadster does the 0-100km/h sprint in 2.4 seconds, 0-200km/h in 6.8 seconds, and can hit a top speed of over 340km/h.

Lamborghini Fenomeno Roadster - Suspension, Brakes & Tyres

The Lamborghini Fenomeno Roadster features manually adjustable racing dampers that allow ride height and setup changes for road or track usage. A 6D sensor mounted close to the Fenomeno Roadster's centre of gravity feeds real-time acceleration and angular velocity data across all three axes to the integrated control system, informing side-slip estimation and traction management.

The Fenomeno Roadster's CCM-R Plus carbon-ceramic brake system uses a three-dimensional long-fibre carbon matrix with a dedicated coating to maintain friction consistency and pad durability at high speeds. A built-in ventilation system manages disc and pad temperatures under sustained dynamic use.

Bridgestone has developed two bespoke Potenza tyre fitments for the Fenomeno Roadster, manufactured in Italy using its Virtual Tire Development process. The standard road fit is the Potenza Sport in 265/30 ZRF21 front and 355/25 ZRF22 rear, available with run-flat technology. A semi-slick next-generation Potenza on 20 and 21-inch wheels is offered as the track-focused alternative, homologated for public roads.
