Lamborghini has unveiled the Fenomeno Roadster, a 15-unit production car that represents an extreme interpretation of open-top supercar design. With a hybrid V12 producing 1080 horsepower, a carbon monocoque chassis, and aerodynamic systems redesigned for roof-off operation, the Fenomeno Roadster addresses a fundamental engineering challenge: delivering track-car performance without the structural protection of a coupe roof.
The car evolves from the Fenomeno Coupe presented in 2025, but Lamborghini approached the roadster conversion as a complete rethink rather than a simple derivative. The chassis had to be reinforced, the cooling architecture revised, and the aerodynamic package entirely reengineered to compensate for the missing roofline. The result is a Two-seater positioned explicitly as a driver’s machine, with interior design philosophy built around what Lamborghini terms “feel like a pilot.”
Powertrain Strategy in Hybrid Form
The Fenomeno Roadster’s HPEV powertrain combines a 6.5-liter naturally aspirated V12 with three electric motors. The 12-cylinder alone produces 835 horsepower at 9,250 rpm with 725 newton-meters of torque, representing a specific output exceeding 128 hp per liter. Two electric motors handle front-axle torque delivery and supplementary acceleration, while a third motor mounted above the dual-clutch gearbox manages regenerative braking and rear-axle torque distribution.
The combined 1080-horsepower output enables 0-100 km/h acceleration in 2.4 seconds and 0-200 km/h in 6.8 seconds, with a top speed exceeding 340 km/h. For an open-topped configuration, these figures demand precise integration between powertrain response, chassis rigidity, and aerodynamic stability at extreme speeds.
A 7-kilowatt-hour lithium-ion battery enables fully electric driving modes, extending Lamborghini’s electrification strategy to a high-performance roadster without sacrificing emotional character. The hybrid system also refines throttle response, torque management, and overall efficiency across the powertrain.
Chassis and Aerodynamic Adaptation
The Fenomeno Roadster employs a carbon-fiber monocoque derived from the aerospace-inspired Monofuselage architecture introduced on the Revuelto. The structure combines a multi-technology carbon-fiber shell with a Forged Composite front end, using a patented liquid-resin blend mixing long and short carbon fibers. This hybrid fiber configuration, appearing here in series production for the first time, achieves coupe-level rigidity with only a modest weight penalty of a few kilograms.
Without a roof panel, open-air aerodynamics demanded a complete redesign. Lamborghini developed a dedicated aero package that maintains the closed car’s downforce and balance while managing airflow turbulence and cooling demands without traditional air scoops. A new flat windshield topped with a carbon-fiber wing element directs air over the cabin toward the engine bay, improving V12 cooling in all driving conditions while reducing cabin buffeting at high speeds.
Carbon-fiber roll bars integrated behind the seats serve dual purposes: structural safety and aerodynamic function. Lamborghini engineered them to reduce wind noise and turbulence at speed, with smooth integration into Speedster-style rear tonneau covers. A transparent engine cover with hexagonal air intakes frames the V12 as a visual focal point, creating the impression of a suspended, perfectly displayed engine block.
Interior Architecture for Driver Focus
The cockpit interprets the “feel like a pilot” philosophy through high-intensity technical design. Carbon fiber, Corsatex microfiber, and proprietary Carbon Skin cover the dashboard, door panels, and contoured seats with red contrast stitching. The interior graphics echo the hexagonal motif visible externally, appearing in ventilation outlets and instrument-cluster displays.
Three digital screens integrated into a system called Pilot Interaction feature hexagonal graphics, haptic buttons, and aviation-inspired controls. The layout prioritizes driver focus on the road or track, minimizing distraction and maintaining legibility during intense driving. Every interface element reinforces the relationship between pilot and machine.
Chassis Dynamics and Braking Sophistication
Lamborghini specifies manually adjustable competition-grade dampers that allow drivers to dial in optimal setup for both track and road use. The system manages chassis movements and maintains dampers in their most efficient operating range, bringing track-day precision to a street-legal roadster.
The CCM-R Plus carbon-ceramic braking system employs a three-dimensional fiber structure of long carbon fibers embedded in a carbon matrix. This architecture delivers high and consistent friction coefficients while specialized cooling maintains brake temperature stability during intense track use. A 6D motion sensor mounted near the car’s center of gravity measures lateral, longitudinal, and vertical acceleration alongside pitch, roll, and yaw data. This real-time information enables the Integrated Power Brake system to optimize vehicle behavior by estimating tire-to-asphalt friction coefficients and lateral drift angle continuously.
Bridgestone Development and Livery Distinction
Bridgestone developed dedicated Potenza Sport tires for the Fenomeno Roadster in sizes 265/30 ZRF21 front and 355/25 ZRF22 rear, with optional Run-Flat technology for continued mobility after puncture. The alternative specification consists of new-generation semi-slick tires engineered for maximum track performance while remaining street-legal. Both configurations were developed and manufactured in Italy using Bridgestone’s Virtual Tyre Development technology.
Aesthetically, the Fenomeno Roadster debuts in a carefully considered livery pairing Blu Cepheus across the upper surfaces with contrasting Rosso Mars below. The color scheme references the 1968 Miura Roadster while honoring Bologna’s municipal colors—blue and red—adding historical and geographical narrative layers to an already densely detailed few-off project.
