Lamborghini has officially debuted the hybrid Sián Roadster, its most powerful convertible to date. The open-top super sports car is limited to just 19 units, all of which have already been sold.

“The Sián Roadster encapsulates the spirit of Lamborghini,” said Stefano Domenicali, Automobili Lamborghini Chairman and Chief Executive Officer. “It is the expression of breathtaking design and extraordinary performance, but most importantly embodies important future technologies. The Sián’s innovative hybrid powertrain heralds the direction for Lamborghini super sports cars, and the open-top Sián Roadster affirms a desire for the ultimate lifestyle Lamborghini as we move towards a tomorrow demanding new solutions.”

The Sián Roadster is based around Lamborghini’s signature V12 engine, delivering 785 horsepower, while a 48-volt e-motor provides an added 34 horsepower. Cranking out a total of 819 horsepower, the convertible travels from 0 to 62 miles per hour in 2.9 seconds, before topping out at approximately 218 miles per hour.

The open-air cabin of the Sián Roadster draws inspiration from the first Countach. Debuting in Blu Uranus, the vehicle is designed to encapsulate the blue of the sky and the green of the fields. Complementing the exterior paint job are Oro Electrum wheels, selected to signify electrification.

Inside, the Sián Roadster incorporates white with Blu Glauco detailing and aluminum elements in Oro Electrum.
