Whether you’re a prospective buyer or an enthusiast, master every nuance of the last V12 supercapacitor halo car.
📌 Definition & Core Identity
Definition: Lamborghini Sián (codename FKP 37) is a limited-production hybrid hypercar combining a naturally aspirated 6.5L V12 (785 CV / 774 hp) with a 48-volt e-motor (34 hp) fed by a lithium-ion supercapacitor – not a conventional battery. Total output: 819 hp, 0-100 km/h in 2.8s, top speed >350 km/h. The supercapacitor delivers instant torque fill and recharges in each braking event, weighing only ~34 kg.
What makes the Sián revolutionary? It’s the first production car using a supercapacitor for hybrid assist, enabling full torque at low revs without added mass. Why did Lamborghini create it? To demonstrate future hybridization while preserving the emotional V12 roar – a technological bridge to the Revuelto. The Sián also previewed active aerodynamics and touch-responsive capacitive controls.
Types of Lamborghini Sián (Detailed)
Sián Coupé (FKP 37)
63 units (2020–2021). Fixed carbon roof, active rear wing, 819 hp. The most “pure” form. Early 2020 VINs (first 20) had stiffer bushings; 2021 coupes received updated damper software. Dry weight: 1,595 kg.
Sián Roadster
19 units, exclusively 2021. Removable carbon hardtop, reinforced sills, revised rear diffuser. Open-air V12 symphony. 0-100 in 2.9s due to slight aerodynamic drag but >20% higher collector premium.
⚡ 2021 (Best) VS 2020 (Worst) – Full Technical Comparison
While both years share the same V12 e-motor architecture, the 2021 model year benefits from production run improvements, software V2.0, and exclusive Roadster variants. Below: exhaustive side-by-side.
| Feature / Aspect | 2020 Lamborghini Sián (Worst) | 2021 Lamborghini Sián (Best) |
|---|---|---|
| Production volume | ~28 coupes (first half of total coupes) | 35 coupes (later batch) + 19 Roadsters = 54 units |
| Hybrid logic (supercapacitor) | Version 1.0: aggressive regen, sharp torque onset | Version 1.2: progressive map, smoother e-boost, improved recuperation |
| Infotainment & HMI | Minor touchscreen lag, slower navigation boot | Optimized capacitive response, wireless Apple CarPlay, quicker start-up |
| Suspension/ADAS | Stiffer default magnetorheological setting (track bias) | Revised calibration with “Strada Plus” – more compliant over bumps |
| Interior materials | Standard carbon trim, early stitching patterns | Available “Pilota” upgrade, extra leather, optional forged carbon |
| Known early issues | 2-3 reports of 12V battery drains, occasional AC vent reset | All resolved; revised battery management and wiring harness |
| Collector value (2025 avg) | $3.0 – $3.3 million | $3.7M – $4.5M (Roadster exceeds $4.8M) |
| Warranty & service campaigns | Some units required hybrid module software recall (#SVC-2022-01) | Factory-installed fixes, no major recalls |
✅ Advantages & Disadvantages of Sián Ownership
Advantages
- ✔ Last true V12 hybrid: No heavy battery, supercapacitor pure innovation.
- ✔ Mind-blowing acceleration: Instant torque fill eliminates turbo lag.
- ✔ Exclusivity peak: Only 82 units – rarer than Bugatti Centodieci.
- ✔ Investment grade: Appreciated ~40% since launch, 2021 roadster likely top future collectible.
- ✔ Emotional styling: Hexagonal design cues, Y-shaped DRLs, active cooling flaps.
Disadvantages
- ✖ Astronomical entry price: $3M+ used, beyond 99.9% of enthusiasts.
- ✖ Costly maintenance: Annual service ~$8k-$12k, supercapacitor health check required.
- ✖ Limited daily usability: Low ground clearance, tiny trunk (only 80L).
- ✖ Depreciation risk if high mileage: Each 1,000 miles may reduce value by 3-5%.
- ✖ 2020 model software-specific quirks: Occasional warning lights that need dealer reset.
🛡️ Is the Lamborghini Sián Safe? Full Analysis
Is it safe for road + track? The Sián features a carbon-fiber monocoque exceeding FIA standards for hypercars. It comes standard with carbon-ceramic brakes (398mm front, 380mm rear), 6-piston calipers, ESC with cornering brake control, and tire pressure monitoring. The supercapacitor is crash-safe front-end mounted, sealed against thermal runaway. However, driver demands respect – 819 hp without modern driver aids like adaptive cruise. Verdict: Very safe compared to pre-2010 hypercars, but not a daily family vehicle. Rearview camera mandatory and excellent on 2021 models.
🏁 Real-World Use & Ownership Experience
How to use the Sián effectively: Ideal for concours d’elegance, hypercar rallies (e.g., Tour Auto), and private track days. The 2021 models offer more forgiving suspension on bumpy roads. Fuel economy averages 9 mpg city / 14 highway, but the hybrid system recovers energy during deceleration. Owners usually drive less than 2,000 miles per year to preserve value. The best use is to experience the naturally aspirated V12 howl beyond 8,500 rpm combined with silent electric boost.
📈 How to Buy a Lamborghini Sián (2025 Guide)
How to purchase: Since all units are sold out, only secondary market. Steps:
- Engage a hypercar broker with access to private collections.
- Authenticate VIN & year: 2020 VINs start with ZHWUE5 … Check production month (May 2020 onwards for 2020MY). 2021 models have later coding, plus all roadsters are 2021.
- Request full service records: Supercapacitor health report mandatory.
- Pre-purchase inspection (PPI) by Lamborghini specialist – verify software version (2021 cars at v1.2).
- Confirm any open recalls: 2020 units might need campaign 21SX (hybrid control unit update).
