The Lamborghini Sián's supercapacitor hybrid system has been getting attention since this limited-run Aventador-based special was announced, but the reality of it is a bit anti-climactic. While the Sián is a bona fide supercar experience, there's nothing unusual or noteworthy about how the hybrid system acts or feels.
Although Lamborghini's hybrid technology is both clever and pioneering, there isn't very much of it. The compact system adds just 75 pounds to the weight of the car, which includes an electric motor integrated into the transmission. Power is stored in a supercapacitor mounted to the rear bulkhead. Lamborghini claims that the supercapacitor setup is three times lighter than a lithium-ion battery with similar energy capacity, although the system's actual storage capability isn't specified. Supercapacitors get their name because they store dramatically more energy than that of a typical capacitor found in electronic devices. Unlike a battery, there's no chemical reaction when charging or discharging, so supercapacitors are very efficient and can charge and discharge rapidly. (In the Sián's case, it can flow up to 600 amps of current.).
