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 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.
The Lamborghini Sián is set to be fully unveiled at the Frankfurt IAA motor show this month.
