Lamborghini Sian FKP 37

The Lamborghini Sian FKP 37, unveiled at the 2019 Frankfurt Motor Show, represents a pivotal moment in Lamborghini's history as the brand's first electrified production car. Named after the Bolognese dialect word for "lightning" or "flash," the Sian combined the iconic Aventador V12 with a groundbreaking supercapacitor-based hybrid system that pointed the way toward Lamborghini's electrified future while celebrating the raw, naturally aspirated power that defined the brand.

The FKP 37 designation honored Ferdinand Karl Piech, the legendary Volkswagen Group patriarch who had championed Lamborghini's place within the corporate family. Piech passed away in 2019 at the age of 82, and the Sian's name referenced his initials and birth year. It was a fitting tribute from a brand that owed much of its modern renaissance to Piech's vision and investment.

At the heart of the Sian was a development of the Aventador SVJ's 6.5-liter naturally aspirated V12, producing 785 horsepower at a screaming 8,500 RPM. This was mated to a 48-volt electric motor integrated into the gearbox, adding an additional 34 horsepower for a combined system output of 819 horsepower. The electric motor's key innovation was its energy storage system: rather than conventional lithium-ion batteries, Lamborghini employed a supercapacitor developed in collaboration with MIT. This supercapacitor could charge and discharge energy three times faster than a lithium-ion battery of equivalent weight, making it ideal for the instantaneous power delivery required in a performance application.

The supercapacitor system charged during braking and deceleration, then deployed its stored energy during low-speed maneuvers and acceleration. The electric motor provided instant torque fill during gear changes, effectively eliminating the momentary power interruption inherent in the ISR single-clutch automated manual transmission. At low speeds, such as parking and maneuvering, the electric motor could propel the car independently, providing smooth, silent operation. The system added only 34 kilograms to the car's overall weight, a remarkable achievement that demonstrated the advantages of supercapacitor technology over conventional battery packs.

Styling was dramatic even by Lamborghini standards. Designed by Mitja Borkert and his team at Lamborghini's Centro Stile, the Sian featured a silhouette inspired by the Countach's angular wedge shape but rendered through a thoroughly modern lens. The Y-shaped headlights, hexagonal exhaust outlets, and six illuminated vertical fins at the rear end created a visual statement that was unmistakable. The body incorporated extensive active aerodynamic elements, and each of the 63 coupes was individually customized by Lamborghini's Ad Personam program, ensuring no two Sians were identical.

Performance was staggering. The combined 819 horsepower propelled the Sian from 0 to 100 km/h in 2.8 seconds, with a top speed exceeding 350 km/h. The all-wheel-drive system distributed torque between all four wheels, providing exceptional traction in all conditions. The pushrod-actuated double-wishbone suspension, derived from the Aventador SVJ, maintained composure at extreme speeds while providing the kind of raw, connected feel that Lamborghini enthusiasts demanded.

All 63 coupes were pre-sold before the car's public unveiling, each commanding approximately 3.6 million dollars before personalization options. Lamborghini subsequently produced 19 units of the Sian Roadster, an open-top variant that maintained the coupe's performance specifications while adding the visceral experience of V12 sound without a roof overhead. Together, the coupe and roadster versions of the Sian served as both a farewell to the naturally aspirated V12 era and a preview of Lamborghini's hybrid future, bridging two technological epochs with characteristic Italian drama.
