The Lamborghini Sián, the marque’s newest release, is a hybrid super sports car that delivers new technologies and mind-bending performance.
The fastest Lamborghini of all time is realized in a new futuristic design that draws on the brand’s style DNA, but with plenty of future-looking touches. Combining a V12 Lamborghini power plant and unique hybrid technologies, the Sián is the super sports car for tomorrow. A 48-volt e-motor, delivering 34 hp, has been incorporated into the gearbox to provide immediate response and improved performance. This is 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.
New Tech For Ultimate Performance
The hypercar’s energy accumulation technology is also a world first. Rather than a lithium-ion battery, the Sián innovates supercapacitor application, offering three times more power than a battery of the same weight in a package that’s three times lighter than a battery producing the same power. Located in the bulkhead, between cockpit and engine, it ensures perfect weight distribution and at only 34 kg, delivers a remarkable weight-to-power ratio, while 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 (577 kW) 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 (602 kW) and still produces the distinctly emotive resonance Lamborghini sound. The extensive use of lightweight materials means the Lamborghini Sián’s weight-to-power ratio is better than that of the Aventador SVJ, and ensures a top speed of over 350 km/h.
With Power Comes Control
The Lamborghini Sián incorporates a highly advanced regenerative braking system, especially developed by Lamborghini that not only allows for greater driver control but, thanks to the symmetric behavior of the supercapacitor, which contrary to normal Li-Ion batteries can be charged and discharged with the same power, fully charges the Sián’s energy storage system every time the vehicle brakes. The energy stored is an instantly-available power boost, allowing the driver to draw immediately on increased torque.
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 percent 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 percent, reducing the 70 to 120 km/h acceleration by 1.2 seconds compared to the Aventador SVJ.
This new level of Lamborghini performance and driving emotion is accompanied by a heightened level of driving comfort facilitated by the hybrid system. The heart-sinking moment when deceleration and missing torque is felt during gear changes powered by a traditional combustion engine is eliminated by the torque upshift fill provided by the hybrid’s e-motor. Yes, the fun literally never stops.
A Design Heading for the Future
Taking futuristic inspiration from the Countach, the Sián’s design is pure and uncluttered. The low front with integrated carbon-fiber splitter is dominated by the ‘Y’-shape 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 extreme Sián design is a clear 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. The Lamborghini Sián utilizes unique material science for the first time in an automotive application. For example, active cooling vanes on the rear use Lamborghini patented technology and are triggered by the temperature generated by the exhaust system, rotating and providing an elegant and lightweight cooling solution.
A Limited-Edition Legend
Not only is the Lamborghini Sián’s dynamism and intriguing technology clear in its design but it represents a new level of haute couture: all of the 63 masterpieces will be individually styled by each owner to create exclusive individuality through Lamborghini Centro Stile in conjunction with Lamborghini Ad Personam.
