Building on the reputation of the Sian Coupe (the automaker’s fastest and rarest supercar), Lamborghini has introduced the Sian Roadster, which is even more exclusive and better-looking.

The most fascinating thing about the Sian Roadster is its powertrain. It features a 6.5L V12 borrowed from the Aventador SVJ as well as a 48-volt mild-hybrid system to produce a whopping 819 horsepower (602 Kilowatts). This huge power enables the Roadster to hit 96 km/h speed in less than 2.9 seconds. The top speed is limited to 350 km/h (218 mph).

While the Sian Coupe was limited to 63 examples, this one is even more exclusive – only 19 units are planned. And we should not be surprised as all are accounted for already.

Another amazing fact is the customization options available for the Sian Roadster. The buyers will have a chance to sit with Lamborghini Ad Personam to build their dream roadster.

The company did not reveal the pricing details yet but we expect it to be in seven figures around $3,700,000. With all this exclusivity, you would be lucky to spot this roadster anywhere in the world.
