Its electric side weighs 34 kg and exists to fill the gaps around a single-clutch gearbox. Sixty-three coupés were made; each was specified through Ad Personam. 2019 · 63 coupés built · Sant'Agata Bolognese ## The price and the proof Indicative road-car band $2.2M–$3M · 2 documented road sales · 2 recorded sales on file. Modeled values are not observed sales. Nothing here is investment advice. Confidence: estimate. The band is anchored by one documented RM Sotheby's coupé sale. Siáns are individually specified and public turnover is too thin for a high-confidence series value. Indicative USD range for the 63-car coupé series; the 19 roadsters are outside this band.

The V12 came from the Aventador family, raised to 785 CV, while a 34 CV motor and supercapacitor made it the company's first production hybrid. The name means lightning in the Bolognese dialect. FKP 37 records Ferdinand Karl Piëch's initials and birth year; Piëch led the Volkswagen Group when Audi acquired Lamborghini in 1998. Production of the coupé stopped at 63, a reference to Lamborghini's 1963 foundation. A separate run of 19 Sián Roadsters followed and is not included in this dossier's count. | Highlight | Detail | | --- | --- | | A capacitor, not a pack | The 48-volt motor and supercapacitor weigh 34 kg together. They add 34 CV, recharge under braking and deliver torque directly to the wheels instead of carrying the mass of a large traction battery. | | Torque between shifts | The motor sits inside the seven-speed ISR gearbox. Its useful job is not electric range; it fills the break in acceleration while the single clutch changes ratio. | | Cooling without a motor | Four vanes around the exhaust react to heat and change shape. No actuator and no sensor: the material itself opens the air path. | | Label | Value | | --- | --- | | Combined power | 819 CV | | 0 to 100 | <2.8 s | | Coupés built | 63 | | Energy store | Supercapacitor | | Public sale | $2'370'000 | ## Technical specifications ### V12 and electric boost | Label | Value | Note | | --- | --- | --- | | Combustion engine | 6'498 cc naturally aspirated V12 | titanium intake valves | | V12 output | 785 CV at 8'500 rpm | factory figure | | Electric motor | 34 CV · 48 V | mounted directly in the gearbox | | Combined output | 819 CV | factory figure | | Gearbox | 7-speed ISR | electric torque fills the interruption between shifts | | Drive | Electronically controlled AWD | Haldex generation IV · rear mechanical locking differential | ### Hybrid and chassis | Label | Value | Note | | --- | --- | --- | | Energy store | Supercapacitor | factory: three times the power of a battery of equal weight | | Electric system mass | 34 kg | 34 CV · 1 kg/CV | | Regeneration | Symmetric charge and discharge | energy available up to 130 km/h | | Structure | Carbon-fibre monocoque | carbon-fibre body | | Steering | Four-wheel steering | | | Cooling vanes | Temperature-reactive | smart material opens them without motors or sensors | ### Sián FKP 37 register 3 documented · public records only.
