The new Lamborghini Sián Roadster has just been unveiled and it looks gorgeous as usual while presenting several new technologies, including 3D printing for extreme customization. Engineered around Lamborghini’s iconic V12 engine with unique hybrid technologies, this open-top hybrid super sports car is intended to offer an anticipation of automative future.
Among other features, the complementary interior that combines white with Blu Glauco detailing and aluminum elements in Oro Electrum also includes new-design air vents produced via 3D printing, which allows customization with a client’s initials. Several recent Lamborghini models had included 3D printed interior elements.
Lamborghini’s Centro Stile and the Ad Personam department work closely with every Sián client to fully personalize the color and finish of their car, so that it fully expresses their personality. Debuting in Blu Uranus, the Sián Roadster encapsulates the blue of the sky and the green of the fields, and is finished with Oro Electrum wheels: the color chosen by Lamborghini to signify electrification.
The Lamborghini Sián Roadster adds a new purity to the already futuristic design of the coupé. The aerial view is evocative of the periscopio line inspired by the first Countach, the long sculptured contours and characteristic aero wings account for an unmistakably powerful profile, the very low front with integrated carbon fiber splitter houses the iconic Lamborghini Y-shape headlights. The extreme and strong rear of the car incorporates Lamborghini’s evocative hexagon design with the rear wing integrated within the profile that extends out only during the driving to enhance performance.
Manufacturing on Demand
The Sián design is a statement of the car’s optimized aerodynamic efficiency and technological prowess: airflow is directed through the front splitters and through the front bonnet, through the side air intakes and outlets and over the rear spoiler, with no loss of aerodynamic efficiency from the roadster’s roofless design. Active cooling vanes on the rear use unique materials-science technology patented by Lamborghini: operation of the vanes is triggered by the reaction of smart-material elements to the temperature generated by the exhaust system, causing them to rotate and providing an elegant and lightweight cooling solution.
‘Sián’ in local Bolognese dialect means ‘flash’ or ‘lightening’, thus denoting the Sián Roadster’s electrification as part of the future hybrid strategy, while maintaining the extraordinary emotion and dynamic performance of naturally aspirated engines.
The Sián Roadster sports Lamborghini’s innovative supercapacitor application: a world-first technology storing ten times the power of a lithium-ion battery. Located in the bulkhead between cockpit and engine, it ensures perfect weight distribution. Three times more powerful than a battery of the same weight and three times lighter than a battery producing the same power, the electric system with the supercapacitor and 34 CV e-motor weighs only 34 kg, thus it delivers a remarkable weight-to-power ratio of 1.0 kg/CV. Symmetric power flow ensures the same efficiency in both charging and discharging cycles: the most lightweight and efficient hybrid solution.
The car’s V12 engine incorporates titanium intake valves and is uprated to 785 CV (577 kW) at 8,500 rpm, thus becoming the most powerful Lamborghini engine ever made, for an all the more enhanced driving emotion and sound experience. Combined with the electric motor, the Sián Roadster delivers a total of 819 CV (602 kW) and reaches a top speed of over 350 km/h.
