Lamborghini Unveils the Hybrid Sián, Its Most Powerful Supercar

The Sián will have a top speed of "over 350 km/h" and will be fully unveiled at the Frankfurt IAA motor show.

Lamborghini has unveiled the Sián supercar, a hybrid that is the company's "most powerful car ever produced."

In order to reach those heights, Lamborghini has created a specialized hybrid powertrain with supercapacitors.

Supercapacitors

Supercapacitors provide benefits as well as drawbacks when compared to electrochemical batteries. They are able to charge and discharge in a matter of seconds. However, they have a low energy storage capacity and aren't typically a viable solution for electric cars.

As Elektrek reports, several companies have been experimenting with hybrid supercapacitors — a mix of batteries and supercapacitors — for use in electric cars.

Now, Lamborghini has revealed their new Sián supercar with hybrid supercapacitors — it's "most powerful car" yet.

In a press release, Lamborghini described the car's capacity:

"The Sián adopts the V12 as the pinnacle of today’s Lamborghini engines and develops a new super sports car powertrain: a unique new hybrid system focuses on providing the highest power possible via the lightest solution."

The company also provided details on its innovative battery solution, which it says is a "world first:"

"Rather than a lithium-ion battery the Sián innovates supercapacitor application: a technology pioneered originally in the Lamborghini Aventador but dramatically developed to store ten times the power. It is three times more powerful than a battery of the same weight and three times lighter than a battery producing the same power."

"The electric system with the supercapacitor and e-motor weighs only 34 kg, thus it delivers a remarkable weight-to-power ratio of 1.0 kg/hp. Symmetric power flow ensures the same efficiency in both charging and discharging cycles: the most lightweight and efficient hybrid solution."

This battery capacity, combined with the V12 engine, means that the Sián delivers a total of 819 hp (602 kW) and has a top speed of “over 350 km/h.”

The car's interior is made with aniline leather in 'Terra di Sant’Agata Bolognese,' developed using 3D printed parts.
