Lamborghini Sián For Sale

Lamborghini Sián: model overview

Revealed in 2019, the Sián FKP 37 was Lamborghini's first production hybrid and a Few-Off milestone: a strictly limited V12 hypercar that introduced electrification to the brand's halo line. Mechanically it builds on the Aventador-derived L539 6.5-litre naturally aspirated 60° V12, here developed with titanium intake valves to 785 CV (577 kW) at 8,500 rpm, and adds a 48-volt electric motor integrated into the gearbox for a combined 819 CV (602 kW), roughly 808 hp. Drive goes to all four wheels through the 7-speed ISR automated manual, Haldex Gen IV all-wheel drive, rear-wheel steering and Lamborghini Dynamic Steering. Lamborghini quotes 0–100 km/h in under 2.8 seconds and a 355 km/h top speed for the coupé.

What sets the Sián apart is its energy storage: instead of a lithium-ion battery it uses a supercapacitor, which Lamborghini says is around three times more power-dense than a battery of the same weight and can charge and discharge symmetrically, ideal for instant torque fill, shift smoothing and acceleration boost rather than electric range. The carbon body quotes the Countach and Terzo Millennio with a Y-shaped light signature, six hexagonal tail lights and a smart-material cooling system that opens passively with heat. Inside, each car was individually specified through Centro Stile and Ad Personam, with 3D-printed components and Poltrona Frau leather. Because configuration drives value, a Lamborghini Sián for sale is a specification- and documentation-led search, colour, exposed carbon, mileage and provenance matter as much as the headline numbers.

Technical specification

The 48V supercapacitor hybrid system

The honest framing matters at this level. The Sián is a V12 mild hybrid, not an EV or a plug-in hybrid: it cannot be driven on electric power alone and has no charging port. Lamborghini stores energy in a supercapacitor rather than a lithium-ion battery, which it says is roughly three times more power-dense than a battery of the same weight and can charge and discharge symmetrically, recovering energy under braking and immediately releasing it. The 34 CV motor is integrated into the gearbox and is used for torque fill, smoothing the ISR single-clutch shifts and boosting acceleration, with Lamborghini citing improved traction in third gear and faster high-speed recovery versus the Aventador SVJ. When confirming a car, the hybrid system's service history should be validated alongside the V12.

Sián Coupé vs Roadster

Both share the 819 CV V12 supercapacitor hybrid powertrain. The coupé (63 cars) is the original FKP 37 launch car, with a fixed electrochromic glass roof, 1,595 kg dry weight, a 355 km/h top speed and 0–100 km/h in under 2.8 seconds. The Roadster (19 cars) is rarer and open-top, slightly heavier at 1,645 kg and taller at 1,158 mm, with a top speed listed at over 350 km/h and 0–100 km/h in under 2.9 seconds. Neither is objectively "better": the coupé carries the FKP 37 identity most directly, while the Roadster is the scarcer of the two. Which suits a given collector depends on whether launch-car status or rarity matters more.

Production, naming and rarity

The numbers are deliberate. The coupé was limited to 63 cars, a reference to 1963, the founding year of Automobili Lamborghini, while the "FKP 37" suffix honours Ferdinand Karl Piëch, born in 1937, who was instrumental in Lamborghini's position within the Volkswagen/Audi group. A further 19 Roadsters bring the Sián family to 82 cars. "Sián" itself means lightning in Bolognese dialect, chosen to reflect electrification and speed. Each car was sold new to a selected client and configured individually, so any "1 of 63" or "1 of 19" claim should be matched to the VIN and factory build sheet, and the exact Ad Personam specification documented.

Market context

The Sián should be positioned as a rare electrified V12 Lamborghini milestone rather than a guaranteed appreciating asset, and asking price should never be read as transaction price. Lamborghini never published one universal MSRP: MotorTrend reported the coupé at about $2.64M, Car and Driver estimated $3.0M–$3.3M, and a factory window sticker shown at online auction listed $2,880,255. Dealer and listing-held cars are currently advertised from roughly $2.9M to $3.6M, but recent public auctions have been lower and specification-sensitive: RM Sotheby's sold a 2021 car for $2,370,000 in Monterey in 2025, and Bonhams reported a 2021 car at €2,012,000 in Monaco in 2026. Rarity alone does not guarantee a premium, configuration, exposed carbon, mileage, country, VAT and import status, provenance and market timing all move the real figure, so each car must be assessed individually.
