Automobili Lamborghini presents the Lamborghini Sián Roadster: an open hybrid super sports car in limited numbers with the legendary Lamborghini V12 engine at its heart, unique hybrid technologies and unprecedented performance for both Lamborghini and hybrid vehicles. The Sián Roadster gives an exclusive group of drivers access to one of the most spectacular cockpits ever. Always under the open sky and in perfect harmony with the incomparable V12 sound of Lamborghini's most powerful engine to date, the driver can experience the extraordinary performance up close and bask in the role of the Sián Roadster as a pioneer of hybridization at Lamborghini.
Lamborghini Sián Roadster
"The Sián Roadster embodies the spirit of Lamborghini," said Stefano Domenicali, Chairman and CEO of Automobili Lamborghini. “It is an expression of breathtaking design and outstanding performance, but above all stands for future-oriented technologies. The Sián's innovative hybrid drive train sets the direction for future Lamborghini super sports cars. The open Sián Roadster intensifies the desire for the ultimate Lamborghini lifestyle on the way to the world of tomorrow, which demands new solutions. ”The Sián Roadster makes its debut in Blu Uranus (blue), a special color chosen by Lamborghini Centro Stile together with the Ad Personam department, who work individually with each Sián customer on the color and personalization options of their roadster. The performance of the Sián Roadster brings a sense of freedom and an euphoric driving experience to life, capturing the blue of the sky and the green of the fields, while its wheels shine in Oro Electrum (gold), the tone chosen by Lamborghini for electrification. The perfectly coordinated interior is presented in an elegant combination of white with details in Blu Glauco (blue) and aluminum elements in gold tone Oro Electrum. The newly designed air intakes, which are manufactured using 3D printing, can be personalized with the customer's initials.
Design of the future
The Lamborghini Sián Roadster impresses with the same futuristic design as the coupe and brings a new stylistic clarity with it with its open interior. The view from above of the Sián Roadster is reminiscent of the iconic Periscopio line of the first Countach, which runs diagonally from the cockpit to the rear and culminates in the aerodynamic air streamers behind the driver and front passenger. Long, distinctive contours and characteristic aerowings give the Sián Roadster an unmistakably powerful profile. The extremely low front with integrated splitter made of carbon fiber comes up with the Lamborghini typical headlights in Y-shape. The clean and unadulterated design of the Sián is a clear statement of the vehicle's optimized aerodynamic efficiency and technological superiority: the airflow is directed through the front splitter and bonnet, the side air inlets and outlets and the rear spoiler, with the roadster passing through it lack of roof does not lose aerodynamic efficiency.
active cooling blades at the rear
Active cooling blades at the rear use a unique material technology patented by Lamborghini. The functioning of the cooling blades is controlled by elements made of intelligent materials: they react to the temperatures of the exhaust system and thus initiate their rotation - an elegant and light cooling solution for the engine. The extreme and robust rear of the vehicle features the hexagon design typical of Lamborghini, including the six hexagonal tail lights inspired by the Countach. The rear spoiler is integrated into the profile and is only extended while driving to improve performance.
Electrification and hybrid technology
The low-set, powerful chassis houses a next-generation V12 drivetrain: "Sián", which means "lightning" in the Bologna dialect, symbolizes the electrification of the Sián Roadster as part of the future hybrid strategy, while the extraordinary emotions and dynamic performance that are inherent in all Lamborghini super sports cars with naturally aspirated engines. The hybrid system of the Sián Roadster offers the maximum possible performance thanks to its outstanding lightweight architecture, which combines the V12 engine with a new drive train. A 48-volt electric motor with 34 hp integrated into the transmission ensures immediate response and an even stronger performance. The electric motor also supports maneuvering at low speeds, such as reversing and parking, with electrical power.
with innovative supercapacitor
The Sián Roadster is equipped with the innovative supercapacitor from Lamborghini, a pioneering solution with ten times the storage capacity of a lithium-ion battery. Thanks to its location between the vehicle interior and the engine, it guarantees perfect weight distribution. Three times more powerful than a battery with the same weight and three times lighter than a battery with the same power. The electrical system with super capacitor and electric motor weighs just 34 kg and scores with a remarkable power / weight ratio of 1,0 kg / PS. The symmetrical power flow ensures the same efficiency in both the charging and discharging cycle, thus ensuring a particularly light and efficient hybrid solution. This advanced technology is used in conjunction with the V12 engine with titanium intake valves and increased output to 785 hp (577 kW) at 8500 rpm. Together with the additional 34 hp of the hybrid system, the Sián Roadster delivers 819 hp (602 kW) and reaches a top speed of over 350 km / h.
state-of-the-art regenerative braking system
The Lamborghini Sián Roadster is equipped with a state-of-the-art regenerative braking system that was specially developed by Lamborghini. Thanks to the symmetrical functioning of the supercapacitor, which - unlike normal lithium-ion batteries - can be charged and discharged with the same power, the Sián Roadster's energy storage system is fully charged every time the vehicle brakes. The stored energy corresponds to an immediately available power boost, through which the driver can immediately use the higher torque when accelerating. This applies to speeds of up to 130 km / h, above which the electric motor switches off automatically. In this way, the vehicle can be driven more flexibly and is over 10% faster than a car without this technology. The innovative system also enables immediate acceleration even in low gears with improved pulling power from the combination of the V12 engine with the hybrid system. The Sián Roadster accelerates from 2,9 to 0 km / h in less than 100 seconds. The improvement in elasticity is even clearer. The pulling power has been improved by up to 10% in third gear, for example.
higher driving comfort thanks to the hybrid system
Thanks to the hybrid system, the Lamborghini Sián Roadster offers even greater driving comfort as well as dynamic handling and performance. The moment that leads to a noticeable reduction in speed due to a lack of torque when changing gears in conventional combustion engines is compensated for by the higher torque provided by the electric motor of the hybrid version: the driver only feels the reverse thrust of the acceleration, whereby all unpleasant jerky movements are eliminated.
