The Sián Roadster’s hybrid system provides the highest power possible via the lightest solution, combining the V12 engine with a new powertrain. A 48-volt e-motor, delivering 34 hp, is incorporated into the gearbox to provide immediate response and improved performance. The e-motor also supports low-speed maneuvers such as reversing and parking with electric power.

The Sián Roadster sports Lamborghini’s innovative supercapacitor application: a world-first technology storing ten times the power of a lithium-ion battery. Located in the bulkhead between cockpit and engine it ensures perfect weight distribution. Three times more powerful than a battery of the same weight and three times lighter than a battery producing the same power, 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. Combined with the additional 34 hp from the hybrid system, the Sián Roadster delivers a total of 819 hp (602 kW) and reaches a top speed of over 350 km/h.

The Lamborghini Sián Roadster incorporates a highly sophisticated regenerative braking system, especially developed by Lamborghini. 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 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. The Sián Roadster accelerates from 0 to 100 km/h in less than 2.9 seconds. The improvement in elasticity maneuvers is even more evident, for example traction force is improved by up to 10% in third gear.
