Origin

Born to test.
Built to survive.

In 2019, Lamborghini was preparing its most technically ambitious road car to date: the Sián FKP 37 — a tribute to Ferdinand Karl Piëch, and a bold declaration of the brand's electrified future. Before a single customer car could be built, every system had to be proven beyond doubt.

Three development prototypes were created. Prototype 01 was the first — and the most significant. Unlike earlier engineering mules built around borrowed platforms, Prototype 01 was a true Sián from birth: the first car to carry an official Lamborghini VIN, built on the actual Sián monocoque, with full Sián body panels and production-intent systems. It was not a precursor to the car — it was the car, in its rawest working form. It carried the greatest burden: emissions homologation, high-speed validation at Nardò, thermal and mechanical endurance runs across Italy and Germany. It accumulated over 47,000 kilometres, each one in service of the production model.

Its fate, like all Lamborghini development prototypes, was predetermined: destruction. This car was never meant to leave the program alive.

PROTOTYPE — NOT FOR SALE
July – September 2019 — Sant'Agata Bolognese
Monocoque Production & Assembly
The monocoque of VIN ZHWEJ7ZD1LLA09403 is produced between July and September 2019. The chassis is framed and painted in the months that follow. After three days of line flow — during which all mechanical components are assembled — the car moves to the R&D workshop for installation of measurement sensors in late November, and is fully completed with all body panels by the second week of January 2020.

World Premiere — Sián FKP 37
Lamborghini unveils its first hybrid hypercar to the world. Prototype 01 has already been running behind closed doors — it is the car that made this moment possible.
Global Debut
January 2020 — Nardò Technical Centre, Italy
First Shake Down — 0 to 1,700 km
Prototype 01 turns its first kilometres at the Nardò Technical Centre — a full systems shake-down covering the initial 1,700 km, checking core functionality across all major systems before rigorous validation begins.

February 2020 — Italy
Emission Pre-Testing — Engine Replacement
Emission pre-tests are conducted on the bench at 1,700–3,000 km. During this phase, the engine is replaced — a standard step in prototype development ensuring the final production-specification unit is validated for regulatory compliance.
Emissions · Engine Replacement · 1,700–3,000 km
May – July 2020 — Nardò Technical Centre, Italy
Full Systems Validation — Handling, Thermal, 48V
Following the Covid-related pause, Prototype 01 returns to Nardò for a comprehensive validation phase from 3,000 to 8,000 km — covering handling dynamics, thermal management, aerodynamics, noise and vibration, electronic functionality, and 48V supercapacitor system calibration and drivability.
Full Validation · 3,000–8,000 km
September 2020 – May 2021 — Germany
Durability Testing — 45,000 km
The most demanding chapter of the car's development life: a nine-month durability campaign in Germany from 8,000 to 45,000 km. Repeated standard road cycles on a proving ground under no-stress driving conditions, culminating in maximum speed verification. Every system on every production Sián owes its durability sign-off to the kilometres logged by this car.

Press, Communication & Benchmark Activities
In its final phase of factory use, Prototype 01 participates in press, communication, and benchmark activities as well as road testing post-restoration — covering a final 45,000 to 47,200 km before being officially retired from the Lamborghini program.

Handover Ceremony — Signed by the Car's Creators
A formal handover ceremony marks the car's passage into private ownership, attended by the designer, project director, and technical development engineer of the Sián FKP 37 — who sign the car's original seat. Full details in the section below.

Paint Protection Film — Bianco Monocerus Preserved
Upon arrival in Romania, the car receives a single treatment: a full application of Uranus Blue paint protection film. The original Bianco Monocerus factory development livery remains intact beneath it — untouched and unaltered exactly as it left Sant'Agata. The PPF protects; it does not replace. Remove it, and the car beneath is factory-original Bianco Monocerus.

Road Registration. Legal Status Secured.
Prototype 01 achieves full road-legal status — one of the only Lamborghini development prototypes ever to be registered for public road use. It is now legally driven, insured, and documented. A virtually unprecedented outcome for any car from Lamborghini's Few-Off division.

The handover
ceremony.

At Lamborghini Bucharest, the car's passage into private ownership was marked with a formal handover ceremony — attended by the people who created it. Rather than a simple transaction, the moment was treated as a closing chapter for the car's development story.

The designer, project director, and technical development engineer of the Sián FKP 37 were present, and each signed the car's original seat — turning it into a permanent, irreplaceable record of the car's authorship.

Technical Identity

Engineering at
the limit.

The Sián FKP 37 introduced two firsts to the supercar world: a supercapacitor-based mild hybrid system delivering instantaneous torque fill, and shape-memory alloy cooling vanes that respond autonomously to heat without electronic actuation. Prototype 01 validated both before a single production car was built.

Of the 63 coupes ever produced,
not one carries the history of this car.
This is the car that made all of them possible.

The production Sián is rare by design. The prototype that validated every one of its systems — and survived to tell the story — is singular.
