Lamborghini's visionary V12 super sports car Sian's limited-edition Roadster model combines cutting-edge hybrid technologies with superior design. This open-top model of Sian, which is the most powerful Lamborghini model ever produced with an electric and internal combustion engine with a power of 819 hp, can go from 0 to 100 kilometers per hour in only 2,9 seconds and can make 350 km / h per hour. Only 19 Lamborghini Sian Roadsters are already sold
Automobili Lamborghini; The limited edition hybrid super sports car Lamborghini, which is designed with Lamborghini's iconic V12 engine, offers unique hybrid performance, offers Lamborghini Sián Roadster. Thanks to the ceilingless design of Sián Roadster, an elite group of drivers will find their place in one of the most magnificent cockpits ever. The deep blue sky will always go with pleasure with Sián Roadster on their heads, in the unique V12 sound ears of the most powerful Lamborghini engine to date, in exceptional performance palms, on Lamborghini's future-leading hybridization route.
Stefano Domenicali, Chairman and CEO of Automobili Lamborghini, said: “Sián Roadster is the summary of the Lamborghini spirit. The expression of breathtaking design and outstanding performance is more importantly the embodiment of the major technologies of the future. Sián's innovative hybrid powertrains herald the direction of Lamborghini's super sports cars. The open-top Sián Roadster reinforces the desire for the perfect lifestyle Lamborghini has to offer, on this road to the future, demanding new solutions. ”
The first color of Sián Roadster will be Blu Uranus. This color was specially chosen by Lamborghini Centro Stile. Centro Stile works with the customer, with support from the Ad Personam (Personalization) department, so that every Sián customer can personalize it all they want, from the color of their Roadster to their finishing touch. The open-top Sián Roadster, which takes its color from the blue of the sky and the green of the meadows, is a reflection of the freedom of performance and driving pleasure, has Oro Electrum wheels. Lamborghini chose this color because it symbolized electrification. Complementing the exterior, the interior reflects the combination of Blu Glauco details, Oro Electrum aluminum elements and stylish white color. Personalization can be provided by adding initials of the customer name to the new design ventilation grilles produced with 3D printing.
The design of the future
While Lamborghini Sián Roadster presents the futuristic design of the coupé, it adds its own purity interpretation with its open cabin as a true roadster. The aerial view of Sián Roadster evokes the iconic Periscopio line inspired by the first Countach. This line extends diagonally from the cockpit back and ends at the aerodynamic air outlets behind the driver and passenger. Sián's long and muscular lines and characteristic aero wings give the Sián Roadster a profile that is too strong to be mixed with another car. The car's very low positioned front features the iconic Lamborghini Y-shaped headlights with integrated carbon fiber splitter.
The pure and clutter-free design of the Sián Roadster is a clear expression of the car's optimized aerodynamic efficiency and superior technological features: The air is guided from the front deflectors, the hood, the air inlets and outlets, and finally the rear spoiler, respectively. Meanwhile, the roadster's ceiling-less design certainly does not compromise aerodynamic efficiency. Lamborghini's patented and unique material science technology is used in the rear active cooling valves. These valves operate smart material components that react to the heat produced by the exhaust system. The components in question enable the valves to rotate and create a stylish and light cooling solution.
In the extreme and muscular rear of the car, Lamborghini's distinctive hexagonal design and six hexagonal lamps inspired by Countach stand out. The rear wing is integrated into the profile and opens only to improve performance while driving.
Means of lightning or lightning
The low, strong chassis is home to a new generation V12 engine: the word 'Sián', which means 'lightning' or 'lightning' at the local Bologna mouth, shows that the electrification of Sián Roadster is part of the future hybrid strategy, while the Lamborghini super sports with natural ventilation system. emphasizes the extraordinary emotion and dynamic performance inherent in the cars.
Sián Roadster's hybrid system combines the V12 engine with a new drivetrain, providing the highest power possible with the lightest solution. The 34-volt e-engine, producing 48 hp, integrates with the transmission to provide instant response and improved performance. The electric motor also supports low-speed maneuvers with electric power, such as turning and parking.
Sián Roadster also has Lamborghini's innovative super capacitor application, a world-class technology that stores ten times more energy than a lithium-ion battery. Located inside the partition panel between the cockpit and the engine, the super capacitor provides a perfect weight distribution. The super capacitor and e-motor electrical system, which is three times stronger than a battery of the same weight and three times lighter than a battery that produces the same power, only weighs 34 kg, thus offering an outstanding power-to-weight ratio of 1,0 kg / hp. . Thanks to symmetrical power transmission, both charging and discharge cycles can be performed with the same efficiency. Thus, the lightest and most efficient hybrid solution is created.
Moreover, this advanced technology is combined with the V12 engine. The engine has been optimized to have titanium intake valves and deliver 8.500 hp (785 kW) at 577 rpm. When 34 hp additional power from the hybrid system is also evaluated, Sián Roadster has a total power of 819 hp (602 kW) and reaches a top speed of over 350 km / h.
Lamborghini Sián Roadster has a sophisticated regenerative braking system specially designed for Lamborghini. Unlike normal Li-ion batteries, the symmetrical movement of the super capacitor, which can be charged and discharged with the same power, fully charges Sián's energy storage system every time the vehicle brakes. The stored energy can be used for instant power loading. This allows the driver to immediately take advantage of high torque up to 130 km / h, with the electric motor automatically disengaging during acceleration, thereby improving flexible maneuvers and offering 10% higher speed compared to a car without this system.
Thanks to the combination of the V12 engine and the hybrid system, the innovative system also provides instant acceleration in low gears with improved traction. Sián Roadster accelerates from 0 to 100 km / h in less than 2,9 seconds. The improvement in elasticity maneuvers has been made more evident. Traction force, for example, was increased by up to 10% in third gear.
Lamborghini Sián Roadster offers dynamic handling and high performance as well as high driving comfort facilitated by the hybrid system. The slowdown and torque reduction experienced during shifting in a conventional combustion engine is eliminated by the upshift torque support of the electric motor in the hybrid system. In this case, the driver only feels backward motion caused by acceleration and is protected from an unpleasant jolt.
