Lamborghini Sián FKP 37

The name Sián comes from the Bolognese dialect of Emilian language siån,{{Cite book|last1=Lepri|first1=Luigi|url=https://books.google.com/books?id=OQ17cAOsXbUC&q=si%C3%A5n|title=Dizionario bolognese-italiano, italiano bolognese|last2=Vitali|first2=Daniele|date=2007|publisher=Edizioni Pendragon|isbn=978-88-8342-594-3|language=it}} which means a flash of lightning (shine). The name was selected to highlight the fact that the car is the first production vehicle produced by the company to include a hybrid supercapacitator component. The suffix FKP 37 is related to the initials and birth year of the late Volkswagen Group chairman Ferdinand Karl Piëch.{{cite news|url=https://www.carmagazine.co.uk/car-news/first-official-pictures/lamborghini/sian/|title=New Lamborghini, Sian: Sant'Agata's first-ever hybrid revealed|date=3 September 2019|work=Car|quote='It augments the potential for Lamborghini as a super sports car brand for tomorrow and for decades to come, even as hybridization becomes more desirable and inevitably essential,' said Lambo boss, Stefano Domenicali. Maurizio Reggiani, Lamborghini's chief technical officer, added: 'Lamborghini is, inherently, a rule breaker. With the Sián, we set ourselves the challenge of creating the best hybrid solution for a Lamborghini to provide the first step in our electrification strategy.'|access-date=3 September 2019}}

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 {{cvt|34|hp|kW PS hp|0|order=out}} 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 {{cvt|773|hp|kW PS hp|0|order=out}}. The total power output is {{cvt|807|hp|kW PS hp|0|order=out}}, making the Sián the most powerful production Lamborghini when it was launched. The engine is connected to a 7-speed automated manual transmission{{cite web|url=https://www.caranddriver.com/news/a28898213/lamborghini-sian-hybrid-photos-info/|title=Lamborghini Sián Kicks Off Lambo's Hybrid Era with 807 HP and a 218-MPH Top Speed|date=3 September 2019|first=Clifford|last=Atiyeh|publisher=Car and Driver|access-date=23 May 2020}} and the car employs an electronically controlled all-wheel-drive system with a rear mechanical self-locking differential for improved handling.{{cite news|url=https://www.autoexpress.co.uk/lamborghini/107798/new-808bhp-lamborghini-sian-is-brand-s-first-hybrid|title=New 808bhp Lamborghini Sian is brand's first hybrid|date=3 September 2019|first=Luke|last=Wilkinson|publisher=Auto Express|access-date=3 September 2019}}

The power for the electric motor is stored in a supercapacitor unit instead of conventional lithium-ion batteries. 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 {{cvt|130|km/h|0}}. The motor supports low-speed manoeuvres such as parking and reversing.{{cite news|url=https://www.autocar.co.uk/car-news/motor-shows-frankfurt-motor-show/lamborghini-uncovers-808bhp-sian-first-hybrid-model|title=Lamborghini uncovers 808bhp Sian as first hybrid model|date=3 September 2019|first=Felix|last=Page|publisher=Autocar|access-date=3 September 2019}}{{cite news|url=https://www.caranddriver.com/news/a28898213/lamborghini-sian-hybrid-photos-info/|title=The Lamborghini Sián FKP 37 starts Lamborghini's hybridisation with 602 kW and 350 km/h|date=3 September 2019|first=Clifford|last=Atiyeh|publisher=Car & Driver|access-date=3 September 2019}}

The exterior design incorporates a wedge shape, a trademark of famed automobile designer Marcello Gandini 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 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. The car was officially unveiled to the public at the 2019 Frankfurt Motor Show configured in a unique "electric gold" paint. It was also renamed to be known as the Sián FKP 37 honouring late Volkswagen Group chairman Ferdinand Piëch. "FKP" are the initials of his name and "37" are the last two numbers of his birth year (i.e. 1937).{{cite web|url=https://www.cnet.com/roadshow/news/lamborghini-sian-fkp-37-ferdinand-piech/|title=Lamborghini Sian adopts FKP 37 surname in honor of the late VW Group chairman|date=10 September 2019|first=Sean|last=Szymkowski|publisher=CNET|access-date=11 September 2019}}

In July 2020, Lamborghini unveiled the convertible roadster version of the Sián FKP 37 simply called the Sián Roadster.{{Cite web |title=Lamborghini Sián Roadster |url=https://www.lamborghini.com/ |access-date=2023-03-29 |website=Lamborghini |language=en}} 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.{{cite web|url=https://www.caranddriver.com/news/a33250882/807-hp-lamborghini-sian-roadster-revealed/|title=807-HP Lamborghini Sián Roadster Revealed, but It's Already Sold Out|date=8 July 2020|first=Mike|last=Duff|publisher=Car and Driver|access-date=11 July 2020}} At the rear, the car features 3D printed carbon fibre air vents on which the buyers can add their initials making each car unique.{{cite web|url=https://www.engadget.com/sian-hybrid-roadster-3d-printing-092005424.html|title=Lamborghini Sian Roadster drops the top, adds custom 3D printed vents|date=9 July 2020|first=Richard|last=Lawler|publisher=En Gadget|access-date=11 July 2020}}

A replica of this model, made from construction bricks, was presented by Lego at the 2022 Paris Motor Show, although Lamborghini was not present at the event.{{Cite web|date=October 20, 2022|title=Le stand Lego et sa Lamborghini Sian au Mondial de Paris 2022|url=https://www.largus.fr/mondial/le-stand-lego-et-sa-lamborghini-sian-au-mondial-de-paris-2022-11065393.html|website=L'argus}}
