Lamborghini has officially pulled the wraps off the Fenomeno Roadster, a high-performance, open-top evolution of its most potent production car to date. Derived from motorsport engineering, this new addition to the “Few Off” series delivers a staggering 1,065 bhp, blending extreme track capabilities with the visceral experience of open-air driving.
Unmatched Exclusivity in the Few Off Series
Positioned as an ultra-rare collector’s piece, the Fenomeno Roadster is even more limited than its fixed-roof counterpart. While the coupé version was limited to 30 units, Lamborghini has confirmed that only 15 examples of the Roadster will be produced globally. This heightened rarity makes it one of the most sought-after models in the Italian manufacturer’s current portfolio, surpassing the exclusivity of its £3 million sibling.
A Masterclass in Hybrid V12 Engineering
At the heart of the Fenomeno Roadster lies a sophisticated plug-in hybrid (PHEV) powertrain, which represents a significant evolution of the system found in the Lamborghini Revuelto. The setup centers on a high-revving, 6.5-liter naturally aspirated V12 engine paired with three electric motors. Two of these motors drive the front axle, while the third is integrated into the eight-speed dual-clutch transmission.
The internal combustion engine alone produces 824 bhp at a screaming 9,250 rpm, with a torque peak of 535 lb-ft at 6,750 rpm. When combined with the electric motors—powered by a centrally mounted 7kWh lithium-ion battery—the total system output reaches 1,065 bhp. This is a notable jump from the Revuelto’s 1,001 bhp, providing the Fenomeno with a superior power-to-weight ratio and enhanced delivery.
Top-Tier Performance Metrics
Despite the lack of a roof, the Fenomeno Roadster retains the blistering acceleration of the coupé. It can sprint from 0-62 mph in just 2.4 seconds and reaches 124 mph in a mere 6.8 seconds. Lamborghini claims the car’s top speed exceeds 211 mph, ensuring that the open-top variant remains competitive with the fastest hypercars on the market.
Advanced Aerodynamics for Open-Air Stability
Transitioning from a coupé to a roadster required a complete overhaul of the vehicle’s aerodynamic profile. Lamborghini’s engineers focused on maintaining the same levels of downforce and stability as the hard-top version. A specialized spoiler positioned above the windscreen is a key feature, designed to redirect airflow over the cockpit and directly into the bespoke rear engine cover.
This airflow management is critical for cooling the V12 engine, especially since the Roadster omits the coupé’s motorsport-derived “S-duct” channel. The redesigned engine cover is punctuated by hexagonal air intakes, a recurring design motif that extends to the cabin’s interior vents and digital displays.
Structural Integrity and Rollover Protection
Maintaining chassis stiffness in a convertible often involves a significant weight penalty, but Lamborghini mitigated this using advanced materials. The Roadster utilizes a carbon fiber monocoque and a front structure crafted from “forged composites.” By using a specific blend of long and short carbon fiber strands, the engineering team achieved a level of torsional rigidity nearly identical to the coupé.
One of the primary engineering hurdles was the integration of rollover protection. To preserve aerodynamic efficiency and reduce wind noise, the protection bars are integrated seamlessly behind the sport seats, serving as a functional part of the car’s structural architecture. While official weight figures have not been finalized, the dry weight is expected to sit very close to the coupé’s 1,772 kg.
Chassis Dynamics and Track-Focused Hardware
The Fenomeno Roadster is equipped with high-end mechanical components to handle its massive power output. This includes manually adjustable racing shock absorbers and a CCM-R Plus carbon-ceramic braking system designed for maximum thermal resistance. The car sits on bespoke Bridgestone Potenza Sport tires (21-inch front, 22-inch rear) for street use, though owners can opt for 20-inch and 21-inch semi-slick Bridgestone tires for dedicated track sessions.
Final Thoughts
The Lamborghini Fenomeno Roadster represents the pinnacle of Sant’Agata Bolognese’s hybrid engineering, offering a rare combination of 1,065 bhp performance and open-air exclusivity. By successfully translating the coupé’s aerodynamic efficiency and structural rigidity into a drop-top format, Lamborghini has created a vehicle that is as much a technical achievement as it is a collector’s masterpiece. With only 15 units available, it stands as a definitive statement on the future of the high-performance V12.
