In another first, the Sian uses a supercapacitor to store energy, rather than more common lithium-ion batteries. According to Lamborghini, the supercapacitor is three times more powerful than a battery of the same weight. The Sian’s advanced regenerative braking system allows the supercapacitor to be fully charged every time the brakes are used. That power is then available for instant boost at any speed up to 80 mph. This electric boost also smooths gear changes, filling in torque during shifts.
