Lamborghini Sián FKP 37
Lamborghini Sián FKP 37 is a mid-engined hybrid sports car manufactured by the Italian automaker Lamborghini. Unveiled online on September 3, 2019, the Sián is the brand’s first production hybrid vehicle.
Nomenclature
The name Sián comes from a Bolognese word that means lightning flash. The name was chosen to emphasize the fact that the car is the first production car produced by the company to include a hybrid supercharger component.
FKP 37 is the initials of the late chairman of the board of directors of the Volkswagen Group, Ferdinand Carl Pieha.
Specifications and performance
Based on the Lamborghini Aventador, the Sián FKP 37 shares an engine with the SVJ variant of the Aventador, but an electric motor integrated into the gearbox adds another 25 kW to the power output. Other changes to the engine include the addition of titanium intake valves, a retuned ECU and a new exhaust system that boosts power to 785 PS. The total power is 819 PS, which makes the Sián the most powerful production Lamborghini.
The engine is connected to a 7-speed automated manual transmission, and to improve handling, the car uses an all-wheel drive system with electronic control and a rear mechanical self-locking differential.
Energy for the electric motor is stored in a block of supercapacitors instead of conventional lithium-ion batteries. The supercapacitor block is integrated with the electric motor in the gearbox for better weight distribution. Supercapacitors were chosen because of their ability to provide three times more power than conventional lithium-ion batteries at the same weight. The unit installed in the car is an evolution of the Aventador starter motor and can store ten times more energy than the unit on which it is based. The regenerative braking system helps generate enough energy to charge the supercapacitors.
The electric motor compensates the effect of deceleration and provides the driver with a surge of power at a speed of up to 130 km/h. The engine supports low-speed maneuvers such as parking and reversing.
Improvements made to the car help it accelerate from 0 to 100 km/h in 2.8 seconds and reach an electronically limited top speed of 350 km/h, but the official top speed has not yet been confirmed.
Design
The exterior design incorporates the wedge shape, a trademark of renowned automotive designer Marcello Gandini, and combines with the design of the Terzo Millennio concept presented two years earlier. The Y-shaped daytime running lights are inspired by the Terzo Millennio, and at the rear, an active fixed rear wing with the number “63” emblazoned on the wings in honor of the company’s founding year creates downforce. Downforce is maximized thanks to prominent side air intakes and a large carbon fiber front splitter.
A clear glass “Peroscopio” panel running from the center of the roof to the engine bay cover adds light and visibility to the passengers, while the six hexagonal taillights are Countach-inspired.
Active cooling blades are used in the rear along with the wing, which are activated by a smart material that reacts to heat. When a certain temperature is reached, the blades turn for additional air flow.
The interior is largely based on that of the Aventador, but the center console has been tweaked and the portrait touchscreen, which first appeared on the Huracán Evo, is one of the key highlights. The leather upholstery was made by the Italian furniture company Poltrona Frau, and 3D-printed details were used for the first time in the interior.
Production
Production of the Sián FKP 37 will be limited to 63 coupe units and 19 roadster units, all of which have already been sold. Sián will be produced by Lamborghini’s Ad Personam division. The car was officially presented to the public at the 2019 Frankfurt Motor Show in a unique “electric gold” color. It was also renamed Sián FKP 37 in honor of the late chairman of the Volkswagen Group, Ferdinand Piech.
“FKP” are the initials of his name, and “37” are the last two digits of his year of birth (i.e. 1937).
Sián FKP 37 Roadster
In July 2020, Lamborghini introduced a convertible version of the Sián roadster. The car was released in a new color called Uranus Blue and is limited to 19 units, all of which have already been sold. Mechanically, the roadster is similar to the coupe, retaining the same engine and supercapacitor hybrid system.
The rear of the car features 3D printed carbon fiber air vents that customers can add their initials to, making each car unique.
