The very first electrified Lamborghini debuted last year in the form of the Sian. It wasn’t a fully-electric model though. Under the hood, it featured a V12 but is paired to a hybrid system using supercapacitors that helped it produce a combined output of 819 horsepower. Only 63 were made, all of which have been spoken for already. Now, Lamborghini has taken things one step further by debuting the even rarer Sian Roadster.

Similar to other Lamborghini roadster models, the open-top Sian maintains the same futuristic design as the coupe which in turn was inspired by the Terzo Millenio concept. Upfront, the fascia is still dominated by large Y-shaped LED daytime running lights flanking a low slung bumper. Meanwhile, at the rear, it has six hexagonal-shaped LED taillights together with a large, integrated rear wing. The engine cover has been reshaped and now features two “hoops” for that proper roadster look.

Interestingly, Lamborghini did not provide photos or details regarding the roof despite being called a roadster. In fact, the official press release says the Sian Roadster is “always open to the sky”.

Powering the Sian Roadster is the same engine as the one found in the coupe. A V12 sourced from the Aventador SVJ produces 785 horsepower. It is then paired to the 48-volt mild hybrid system for a combined output of 819 horsepower. As with most roadsters, acceleration figures are down when compared to the coupe. 0 to 100 km/h now takes “under 2.9 seconds” as opposed to the coupe’s “under 2.8 seconds”. The top speed is rated at over 350 km/h.

Much like the coupe, the Sian Roadster will be sold in limited numbers only. It might actually be one of the rarest Lamborghinis in the world as only 19 units will be built. Before you bring out your checkbook to order one, all 19 Sian Roadsters have been sold even before the car was launched. Tough luck for those who’ve been wanting to get a droptop or hardtop Sian.
