The 63 club
Here is the whole rarity story in one line: Lamborghini built 63 of these, 63 for 1963, the year the company was founded, and every one was sold before the public saw the car. If you're scrolling this while you wait on your car repair, the odds you'll ever ride in one are about the same as that repair coming in under the estimate. It happens. Not often.
Two names, two stories
Sián means "flash" or "lightning" in the Bolognese dialect spoken around Lamborghini's home in Sant'Agata Bolognese. Lamborghini chose it because this was the first time a production Lamborghini used electricity to help move the car.
FKP 37 was added to honor Ferdinand Karl Piëch, born in 1937. Lamborghini unveiled the car at the Frankfurt Motor Show (IAA) in September 2019.
First hybrid, with a twist
Most hybrids store electricity in a battery. The Sián uses a supercapacitor, and Lamborghini called it a world first for a hybrid. According to Lamborghini's press release:
- The supercapacitor is three times more powerful than a battery of the same weight, and three times lighter than a battery making the same power.
- It sits in the bulkhead between the cabin and the engine, for weight balance.
- The 48-volt electric motor (34 hp) is built into the gearbox, and Lamborghini says it's the first low-voltage hybrid with a direct connection between electric motor and wheels.
- The motor helps with reversing and parking, and boosts acceleration up to 130 km/h, when it disconnects.
- Regenerative braking recharges it every time you slow down.
Put together with the 6.5-liter V12, total output is 819 CV, about 808 hp. Lamborghini called it the most powerful Lamborghini ever produced at the time, with the lowest weight-to-power ratio of any V12 Lamborghini. Lamborghini quotes 0–62 mph in under 2.8 seconds and a top speed over 350 km/h; its spec sheet lists 355 km/h.
The design, decoded
If the Sián looks a little like a Countach that went to art school, that's on purpose. Lamborghini's press release says the design takes "futuristic inspiration from the Countach," with the "Gandini line" visible in its profile. Around back are six hexagonal taillights inspired by the Countach.
One more nerdy detail: Lamborghini says vents behind the engine cover open by themselves when the exhaust area gets hot, using smart materials that bend with temperature, no motors or sensors. It's a car part that sweats on its own. Most cars do something on their own when they get hot too. It usually involves a warning light.
The one Darin photographed
Darin took the photo on this card inside Lamborghini Miami: a graphite Sián with green accents parked on the showroom floor, a couple of people standing nearby for scale. It's a real phone photo, not a press shot.
We couldn't find a current exact Sián listing on Lamborghini Miami's website when we checked on 21 October 2026, so the photo and button go to their inventory page instead. Price on request, which in this neighborhood means "please sit down first."
Why it turns heads
Partly the shape. Mostly the scarcity. People who know cars know what 63 means. People who don't know cars can still tell this isn't the one they see at the mall. Either way the phones come out.
The honest part
Upkeep: pending. Our rating: pending. Everything technical above comes from Lamborghini's 2019 press release and its Sián FKP 37 pages, linked below.
