Lamborghini Unveils Sián At Frankfurt Motor Show
Lamborghini unveils the Lamborghini Sián at the Frankfurt Motor Show. Sián is a hybrid super sports car delivering new technologies and unsurpassed performance in the hybrid sphere.
The Sián is engineered around unique hybrid technologies, delivering the extraordinary emotion and exceptional dynamic performance of a naturally aspirated Lamborghini super sports car, while meeting a future demanding electrification.
“The Sián is a masterpiece in possibilities,” says Stefano Domenicali, Automobili Lamborghini Chairman and Chief Executive Officer. “Not only does the Sián deliver a formidable hyper-car design and engineering tour de force today, but it also augments the potential for Lamborghini as a super sports car brand for tomorrow and for decades to come, even as hybridization becomes more desirable and inevitably essential. The Lamborghini Sián represents the first step in Lamborghini’s route to electrification and expedites our next-generation V12 engine. Its Sián moniker, meaning ‘flash of lightning’ in Bolognese dialect, denotes the first electrification of a Lamborghini production car and confirms our strong connection to the territory in which we operate. With the Sián, Automobili Lamborghini demonstrates its dynastic strength as a legendary super sports car brand for the future.”
The Sián adopts the V12 as the pinnacle of today’s Lamborghini engines and develops a new super sports car powertrain: a new hybrid system focuses on providing the highest power possible via the lightest solution.
A 48 volt e-motor, delivering 34 hp, has been incorporated into the gearbox to provide immediate response and improved performance: the first time in any low-voltage hybrid that a direct connection has been made between electric motor and wheels. The e-motor also supports low-speed maneuvers such as reversing and parking with electric power.
The energy accumulation technology is a world first. Rather than a lithium-ion battery, the Sián innovates supercapacitor application. It is three times more powerful than a battery of the same weight and three times lighter than a battery producing the same power. Located in the bulkhead between the cockpit and engine it ensures perfect weight distribution. The electric system with the supercapacitor and e-motor weighs only 34 kg,
This technology combines with the V12 engine, which incorporates titanium intake valves and is uprated to 785 hp (577 kW) at 8,500 rpm. Combined with the additional 34 hp from the hybrid system, the Sián delivers a total of 819 hp (602 kW), and still produces the distinctly emotive resonance demanded from a Lamborghini engine. The Sián’s weight-to-power ratio is better than that of the Aventador SVJ, achieved through extensive use of lightweight materials. The Sián reaches a top speed of over 350 km/h.
The Lamborghini Sián incorporates a regenerative braking system. The energy stored is an instantly-available power boost, allowing the driver to draw immediately on increased torque when accelerating away, up to 130 km/h when the e-motor automatically disconnects, improving the elasticity maneuvers and making it more than 10% faster than a car without this system.
Taking inspiration from the Countach, the Gandini line is evident in its profile, while the silhouette introduces new features such as the characteristic aero wings, giving the Sián an unmistakable profile. The Lamborghini ‘Y’ shape can be seen in the NACA air inlets on the doors, glass elements are included in the engine cover, and the diagonal line features in the front hood, as in the Countach.
In its long, honed, sculptured contours, like the Countach, the Sián’s design is pure and uncluttered. The low front with the integrated carbon-fiber splitter is dominated by the ‘Y’-shaped headlights, used for the first time to reflect the signature design of the night lights, originally designed for the Lamborghini Terzo Millennio.
The extreme and strong rear of the car incorporates the hexagonal design so linked with Lamborghini, including six hexagonal tail lights inspired by the Countach. The rear wing is integrated within the profile and extends out only during the driving to enhance the performance.
In the roof, the ‘Periscopio’ tunnel that originally incorporated a rear mirror in the Countach, adds a bold feature that links with the slats of the rear engine cover and important elements contributing to the car’s aerodynamic efficiency.
The Lamborghini Sián will be unveiled to the world’s media and the public at the Frankfurt IAA motor show 2019.
