Lamborghini Goes Hybrid with Lighting Fast Sian, Quickest Lambo Ever

At next week’s Frankfurt Auto Show in Germany, a very special Lamborghini, painted with golden flakes and golden crystals, will shine proudly in the carmaker’s booth. It’s called Sian, it is based on the Aventador and it is the first hybrid ever created by the Italians.

Lambo chose the name Sian for this car because in the Bolognese dialect that supposedly means flash or lighting. And they were right to name it so, as pretty much everything in it is lighting fast.

First, the car itself. It is powered by the Aventador-proven V12 that develops 785 hp, only this time working in conjunction with a 48-volt e-motor that cranks out an additional 34 hp. That brings the total to 819 hp, the largest figure ever squeezed by Lamborghini from one of its cars.

With this powertrain fitted, the Sian can reach 62 mph in under 2.8 seconds, in effect making it the Lamborghini with the fastest acceleration time ever made.

But that’s not all. The carmaker decided to replace the lithium-ion battery usually used in hybrid systems with a supercapacitor. According to them, this is the first time such a thing has been done on a hybrid car.

The supercapacitor is three times more potent than a battery of the same weight, and it can be recharged to full capacity instantly every time the car brakes. Using this solution means power boost is instantly available, and the Sian is “more than 10% faster than a car without this system.”

Despite adding the e-motor and the supercapacitor, the car’s weight has not increased by much. The two new pieces of hardware weigh a combined 34 kg, translating into the “lowest weight-to-power ratio of the Lamborghini V12 family ever:”

Design-wise, the Sian stands out thanks to the unique aero wings, the Y shape featured on the air inlets on the doors, glass elements in the engine cover, and the diagonal line features in the front hood. All these elements, apparently, are supposed to remind of the Countach.

Lamborghini plans to build 63 Sian models. All of them have already been sold for yet undisclosed prices.
