Specifications and performance

Based on the Lamborghini Aventador, the Sián FKP 37 shares its engine with the SVJ variant of the Aventador, but an electric motor integrated into the gearbox adds another to the power output. Other modifications to the engine include the addition of titanium intake valves, a reconfigured ECU and a new exhaust system raising the power output to . The total power output is , making the Sián the most powerful production Lamborghini when it was launched. The engine is connected to a 7-speed automated manual transmission and the car employs an electronically controlled all-wheel-drive system with a rear mechanical self-locking differential for improved handling. The power for the electric motor is stored in a

. The supercapacitor unit is integrated with the electric motor into the gearbox for a better weight distribution. A supercapacitor was chosen as it provides three times the power of a conventional lithium-ion battery of the same weight. The unit installed in the car is an evolution of the Aventador's starter motor and can store ten times more power than the unit it is based on. A regenerative braking system helps generate enough energy to recharge the supercapacitors. The electric motor counters the effect of deceleration and provides a power boost to the driver at speeds up to . The motor supports low-speed manoeuvres such as parking and reversing. The improvements made to the car help accelerate it from 0 to in 2.8 seconds and a top speed of 355 km/h as stated


Design

The exterior design incorporates a wedge shape, a trademark of famed automobile designer
Marcello Gandini Marcello Gandini (26 August 1938 – 13 March 2024) was an Italian Automotive design, car designer widely known for his work with the Italian car design house Gruppo Bertone, Bertone, where his work included designing the Alfa Romeo Carabo and A ...
and mixes that with the design of the Terzo Millennio concept introduced two years prior. The Y-shaped daytime running headlights are inspired by the Terzo Millennio while at the rear an active fixed rear wing with the number "63" embossed on its winglets to honour the company's year of incorporation creates downforce. Downforce is maximised by the model's prominent side air intakes and large carbon-fibre front splitter. A transparent "Peroscopio" glass panel runs from the centre of the roof and rolls back into the slatted engine cover adds light and visibility for the occupants, and the six hexagonal taillights are an inspiration from the Countach. Along with the wing, active cooling vanes at the rear are used which are activated by a smart material that reacts to heat. When a certain temperature is reached, the vanes rotate for extra airflow. The interior is based heavily on the Aventador's interior, but the centre console has been tidied up and a portrait touchscreen first seen in the Huracán Evo is one of the key differences. The leather upholstery is from Poltrona Frau, an Italian furniture company and 3D printed parts are used on the interior for the first time.


Production

Production of the Sián FKP 37 was limited to 63 units for the coupe and 19 for the roadster and all have already been sold. Lamborghini's Ad Personam division will be responsible for the manufacture of the Sián.

Sián Roadster

In July 2020, Lamborghini unveiled the convertible roadster version of the Sián FKP 37 simply called the Sián Roadster. The car was launched in a new colour called Uranus Blue and is limited to 19 units, all of which have been already sold. Mechanically, the Roadster is similar to the coupe retaining the same engine and the supercapacitor hybrid system. At the rear, the car features 3D printed carbon fibre air vents on which the buyers can add their initials making each car unique.
