It offers a combined output of 808 hp. The system uses 48-volt, 34hp electric motor that is incorporated into the gearbox. It provides immediate response and better performance.

Electric motor in Lamborghini Sián supports low-speed manoeuvring that enables the supercar to execute reversing and parking under electric power alone. Another first thing in the Lamborghini Sián is the energy storage unit in place of a lithium-ion battery pack. Lamborghini also make use of supercapacitor that is three times more powerful than a battery of the same weight and three times lighter. The said supercapacitor is mounted in the bulkhead between the cabin and the engine for optimal weight distribution. Lamborghini stated that electric motor and supercapacitor weighs just 34kg and helps in achieving a weight-to-power ratio of 1.0 kg/hp.
