The Lamborghini Sián hybrid super sports car previews the future
At the Frankfurt Motor Show Automobili Lamborghini unveils the Lamborghini Sián: a hybrid super sports car delivering new technologies and unsurpassed performance in the hybrid sphere.
The fastest Lamborghini of all time is realized in a new futuristic design; drawing on the brand’s style DNA, but clearly a design for a new era. Taking the most iconic V12 Lamborghini power plant of today, 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.
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: a technology pioneered originally in the Lamborghini Aventador but 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 ensures perfect weight distribution. The electric system with the supercapacitor and e-motor weighs only 34 kg, thus it delivers a remarkable weight-to-power ratio of 1.0 kg/hp. Symmetric power flow ensures the same efficiency in both charging and discharging cycles: the most lightweight and efficient hybrid solution.
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 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 highly advanced regenerative braking system, especially developed by Lamborghini. Thanks to the symmetric behavior of the supercapacitor, which contrary to normal Li-Ion batteries can be charged and discharged with the same power, the Sián’s energy storage system is fully charged every time the vehicle brakes. 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.
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.
Sián will be produced in a limited series of just 63 units (all already sold) honoring the foundation year of Automobili Lamborghini.
