Sián FKP 37

  • The Sián FKP 37, whose name means “lightning” in Bolognese dialect, is the first super sports car powered by a V12 with hybrid technology based on a supercapacitor. A real masterpiece of engineering and technology with an extraordinary design, both functional and futuristic, that elicits excitement right from the first glance.
  • Produced in just 63 units, the first few-off hybrid car boasts the lowest power-to-weight ratio of any other Lamborghini with a V12 engine, and its top speed exceeds 350 km/h.
  • With the first application of supercapacitors in the world in the hybrid segment, the Sián FKP 37 looks to the future without forgoing the emotions of a Lamborghini, and also paves the way for a new technology of autonomous actuation in the automotive world.

The Sián Roadster is the first hybrid open-top super sports car equipped with pioneering supercapacitor technology and an innovative use of materials science.

  • This technological gem combines the most powerful V12 engine ever with a new power pack, thus introducing an innovative hybrid system that offers the maximum power to the more limited weight.
    The aerodynamic efficiency of the Sián Roadster is optimized by the pure design, which reinterprets the forms in the open-top cabin, creating an unmistakable futuristic profile.


  • The Sián FKP 37 is the first super sports car powered by a V12 engine and hybrid technology based on supercapacitors. Its powerful V12 engine, coupled with electric boost, creates an unrivaled gem of engineering and technology. Sián—lightning in Bolognese—is a name that captures the car’s true character, foremost its speed, which exceeds 220 mph (350 km/h).


  • The Design DNA of Lamborghini is taken to its peak levels: inspired by the Countach, the Sián FKP 37 has sharp lines, aerodynamic elegance and an unmistakable silhouette.
  • Its totally carbon fiber body leaves you breathless. The electrochromic roof and moving surfaces controlled by smart materials are sculpted by innovative lines. The Terzo Millennio-inspired headlights leave behind an indelible luminous signature that will shape future Lamborghini design.


  • Inside the Lamborghini Sián FKP 37, luxurious Italian craftsmanship meets state-of-the-art technology with a cabin designed to provide a driving experience that combines adrenaline-charged acceleration with utmost comfort. Additionally, the passenger compartment features recurring design elements that reflect classic Lamborghini style, including Y-shaped features and hexagonal shapes, rendered to perfection with meticulous attention to every detail.


  • The new Sián FKP 37 is a technological tour de force, able to fire up incredibly strong emotions. The most extraordinary innovation is the hybrid system, which delivers maximum power with minimal weight. The innovative, lightweight mild-hybrid architecture uses a lithium-ion supercapacitor, which is three times more powerful than a battery of the same weight. It is a low-voltage 48V system, enabling peak currents of up to 600A. Powered by this current, the electric motor delivers engine torque directly to the rear wheels, and during braking uses the inertia to recharge the capacitor. The electrical power flow is symmetrical, for the same efficiency during the charge and discharge cycles, without overheating.
  • With the Sián FKP 37, a new autonomous technology is entering the automotive world. At the back of the engine hood are autonomous vent flaps actuated by smart materials that are temperature sensitive by nature. These flaps open independently when the temperature around the exhausts becomes too extreme, without the aid of electric controls and sensors, relying only on the thermal distortion of the material. With its carbon-fiber monocoque, titanium intake valves, active aerodynamics and rear-wheel steering, the Sián FKP 37 employs cutting-edge technology everywhere—not only in the world’s first supercapacitor hybrid system.
