“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, it 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 or 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.”
“Lamborghini’s strategic heritage in one-off and very limited series cars is not only a commitment to exclusivity but a presentation of future designs and technologies. With this car, we set ourselves the challenge of creating the best hybrid solution for a Lamborghini super sports car to provide us with the first step on our electrification strategy,” says Maurizio Reggiani, Chief Technical Officer. “Lamborghini is inherently a rule breaker, a challenger, always pushing what is possible to find a better solution. With the Sián we are defining our route to innovation and we are setting new rules in new technologies, instead of just following existing solutions. The result is the Lamborghini Sián, which includes the world-first application of a supercapacitor for hybridization and new materials technology.”
The energy accumulation technology is a world first. Rather than a lithium-ion battery the Sián innovates supercapacitor application: a technology pioneered originally in the Lamborghini Aventador but has been developed to store ten times the power. 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 cockpit and engine it provides better weight distribution. The electric system with the supercapacitor and e-motor weighs only 34 kg. It delivers a weight-to-power ratio of 1.0 kg/hp. Symmetric power flow ensures the same efficiency in both charging and discharging cycles.
This advanced technology combines with the V12 engine, which incorporates titanium intake valves and is uprated to 785 hp at 8,500 rpm: the highest output ever from a Lamborghini power plant. Combined with the additional 34 hp from the hybrid system, the Sián delivers a total of 819 hp. The Sián’s weight-to-power ratio is better than that of the Aventador SVJ, achieved through extensive use of lightweight materials.
The innovative system also delivers instant acceleration in low gears, with improved traction force provided by the combination of V12 engine and hybrid system. This makes the Sián the fastest-accelerating Lamborghini ever, achieving 0 to 100 km/h in less than 2.8 seconds. The improvement in elasticity maneuvers is even more evident. Traction force is improved by up to 10% in third gear and the 30 to 60 km/h acceleration time is improved by 0.2 seconds compared to the Aventador SVJ. In higher gears and lower speeds the electric motor increases traction force by up to 20%, reducing the 70 to 120 km/h acceleration by 1.2 seconds compared to the Aventador SVJ.
“The fastest Lamborghini must be a visual and symphonic feast, as remarkable to those who see it pass by as those privileged to drive it, “says Mitja Borkert, Head of Design at Automobili Lamborghini. “It takes inspiration from the Countach, but the Sián is a futuristic icon, not retrospective. Exclusivity is enhanced by total Ad Personam personalization that every one of the 63 Sián owners has the privilege of creating, in conjunction with me and the Centro Stile team: 63 individuals worldwide will own not only the fastest, but a unique Lamborghini.”
