Sensual curves meet jagged angles in the remarkable Sian, Lamborghini’s first hybrid and the first car in production history to use a supercapacitor hybrid system
Lamborghini has chosen a radically different way of dipping its toe in the waters of hybridization with the announcement of its new Sián, which couples a screaming, naturally aspirated V12 engine with a supercapacitor-based secondary electric system.
Supercapacitors, as opposed to batteries, offer a unique set of advantages and drawbacks to automakers. They have enormous charge and discharge rates, meaning they can put out huge amounts of power, charge up almost instantly, and pull in a much larger amount of energy through things like regenerative braking, in which a battery’s ability to accept charge becomes a limiting factor. They also don’t deteriorate over time, maintaining their performance over millions of cycles.
