Lamborghini's first hybrid hypercar — a V12 supercapacitor-assisted limited edition.
Launched at the 2019 Frankfurt Motor Show, the Sián FKP 37 paired the Aventador SVJ's 6.5-litre V12 with a 48-volt supercapacitor-assisted mild-hybrid system for a combined 819 CV (808 hp). Production was capped at 63 coupes and 19 FKP 37 Roadster derivatives, all allocated to existing collectors.
The Sián anchors the limited-edition Lamborghini line between Centenario and Revuelto and is widely interpreted as the test bed for the V12 hybrid drivetrain that followed.
First hybrid V12 Lamborghini and a closed-production halo car; bridges Aventador and Revuelto.

Start with identity, paperwork and originality. For the Lamborghini Sián, the strongest cars have continuous ownership history, matching numbers where applicable, original books and tools, factory build documentation and evidence of work by manufacturer-approved specialists. Documented Lamborghini delivery file, original colour and unmodified specification.
Mechanically Aventador-derived; supercapacitor system service routes via Lamborghini dealers only. A proper pre-purchase inspection includes cold-start behaviour, ECU diagnostics and fault-code history (where applicable), leak-down or compression testing, underbody photography, suspension and chassis inspection, brake condition and a long enough road test to expose heat-related faults. Deferred maintenance on a car of this class is almost always more expensive than buying a better-sorted example.
Use a paint-depth gauge, lift access and a specialist familiar with the model's factory panel gaps and finish standards. Collector value is dramatically affected by structural repairs, refinished panels, poor paintwork and missing factory trim or option content. Documented cosmetic refresh is acceptable; concealed accident or fire damage must be priced severely.
First-allocation cars in factory-correct, restrained specifications hold the firmest values. Specification, colour, options and limited-build variants move values significantly. Buy the best-documented example in the most desirable specification you can justify, rather than a tired example of a rarer derivative that will need years of corrective work.

Closed-production hybrid V12 Lamborghini halo. Roadster and first-allocation coupe provenance lead. Coupe results have corrected sharply from original list, and standard secondary trades carry the most exposure.
