This is a true roadster rather than a convertible. There is no roof at all, so the driver and passenger are exposed to the elements at all times. Assuming owners ever take their Sián Roadsters out of their climate-controlled garages, that is.
Like the Sián coupe, the roofless version is a hybrid pairing a 6.5-liter V-12 with an electric motor integrated with a 7-speed automatic transmission. Instead of a battery pack, the Sián uses a supercapacitor to store energy. Located between the cockpit and engine compartment to improve weight balance, it’s lighter than a battery pack of comparable capacity, according to Lamborghini.

Total system output is 807 hp, with 774 hp contributed by the V-12 alone. At the time of the Sián Roadster’s launch, Lamborghini quoted a 0-62 mph time of 2.9 seconds and a 217-mph top speed. The automaker said “Sián” means “flash” or “lightning” in the Bolognese dialect of Italian—an appropriate moniker for a quick-accelerating hybrid supercar.
The Sián Roadster was priced at $3.2 million when new, but the asking price for this one is closer to $4.6 million at current exchange rates. But with just 19 examples built, the chances to own a Sián Roadster are few and far between.
