The Lamborghini Sián is a limited-production hybrid supercar built on the V12 platform that underpins the Aventador, representing Lamborghini's first series production electrified model. Deliveries began in 2020, with the total run capped at 63 units for the coupe, a figure chosen in reference to 1963, the year Lamborghini was founded. The car uses a 48-volt mild hybrid system incorporating a supercapacitor rather than a conventional lithium-ion battery, supplementing the naturally aspirated 6.5-liter V12 to produce a combined output of 819 horsepower. A Roadster variant followed with the same powertrain and an equally restricted production allocation of 19 units.
