Lamborghini Sián FKP 37: The World’s First Supercapacitor-Powered Supercar

Electrified Fury - Speed has always been the heartbeat of Lamborghini, but in recent years, the race has shifted from pure combustion power to the electrified future. In this fast-changing automotive world, the Italian brand decided it wouldn’t just keep up — it would strike like lightning. That “lightning” is more than a metaphor; it’s the very name of their groundbreaking creation, the Lamborghini Sián FKP 37, the world’s first production car to use a supercapacitor in its hybrid system. Unveiled at the 2019 Frankfurt Motor Show, this machine wasn’t just another step forward — it was a bold leap into a new era.

The name “Sián,” taken from the Bolognese dialect, perfectly captures the speed and electricity behind the concept. Pair that with “FKP 37,” honoring Ferdinand Karl Piëch — the man born in 1937 who played a key role in bringing Lamborghini into the Volkswagen Group — and you have a title that carries both cultural spark and corporate history. The Sián wasn’t just a car; it was a statement that Lamborghini’s DNA would remain intact, even as the company embraced electrification.

Its design language is unmistakably Lamborghini, yet it feels like a vision pulled from tomorrow. Drawing inspiration from the Terzo Millennio concept, the Sián adds sharper, more aggressive lines while nodding to the legendary Countach. Mitja Borkert, Lamborghini’s Head of Design, described it as a “futuristic icon” — an apt description when you see the sculpted aerodynamic forms that look like they could slice through both air and time. The Sián doesn’t just roll past; it stages a visual and auditory performance every time it moves.

Under its striking skin lies a masterpiece of engineering: a naturally aspirated V12 engine producing a colossal 785 horsepower — the most powerful V12 Lamborghini had ever built at the time — paired with a 48-volt electric motor that adds another 34 horsepower. Together, they deliver a combined output of 819 horsepower, enough to push the car beyond 350 km/h and launch it from 0 to 100 km/h in under 2.8 seconds. Numbers like these make it clear: this isn’t just about going green; it’s about going faster than ever.

But the Sián’s real headline isn’t its power figures — it’s the technology driving its hybrid system. Instead of traditional lithium-ion batteries, Lamborghini equipped the Sián with a supercapacitor. Unlike batteries, a supercapacitor can be recharged almost instantly, stores and releases energy more efficiently, and doesn’t degrade significantly over time. Energy is harvested during braking and immediately available for acceleration, meaning the system is lighter, quicker, and more durable than conventional solutions. For a performance car, that’s game-changing.

Of course, this level of innovation came with exclusivity. Lamborghini built just 63 units of the Sián, each carrying a price tag of around $2.5 million. Every single one was spoken for before the public even saw the car in person. For most people, the closest they could get was admiring it under the bright lights of Frankfurt in 2019 — a fleeting glimpse at a machine that bridged Lamborghini’s past glory with its electrified future.

The Sián FKP 37 remains a rare and shining example of how tradition and innovation can coexist without compromise. In a time when supercars are being redefined by new technology, Lamborghini proved that evolution doesn’t have to mean losing the soul. Sometimes, it can mean striking faster, brighter, and louder than anyone thought possible. *** [EKA [06092019] | FROM VARIOUS SOURCES | LAMBORGHINI | MOTOR1 | POCKET-LINT ]
