Lamborghini Sián Roadster 2020

The 2020 Lamborghini Sián Roadster brings the Sián concept into an open-top format, without a fixed roof. Unveiled in July 2020, it keeps the same hybrid layout as the coupé, combining a naturally aspirated 6.5-liter V12, a 48-volt electric system, and a supercapacitor instead of a conventional lithium-ion battery. Lamborghini quotes a total output of 819 hp, with 785 hp coming from the combustion engine and 34 hp from the electric side. Built in extremely limited numbers, the Roadster is more than a styling exercise: it is the convertible expression of a Few-Off Lamborghini created to test exclusive technical and design ideas.

History

The Sián began as a Lamborghini Few-Off project meant to push the brand’s technical and stylistic direction further. The FKP 37 coupé was revealed in 2019, and the open-top version followed in 2020. The name “Sián” refers to lightning in the Bolognese dialect, while FKP 37 pays tribute to Ferdinand Karl Piëch, born in 1937. Within that framework, the 2020 Roadster extends the same concept without changing its core identity. It retains the hybrid mechanical package built around a 6.5-liter V12 and an electric motor integrated into the transmission, using a supercapacitor rather than a conventional battery.

Anecdotes

The Sián name links the idea of “lightning” to Lamborghini’s identity, while the FKP 37 designation preserves the reference to Ferdinand Karl Piëch. For the Roadster, another notable point is the use of a supercapacitor, an unusual choice compared with a conventional lithium-ion battery. The dossier also notes that materials and visual details can vary widely from one car to another because of the extensive personalization process.

Production

The Lamborghini Sián Roadster was unveiled in 2020, and production is limited to 19 units. The dossier presents it as a strictly limited offshoot of the Sián concept, without any fundamental mechanical change over the coupé. Each example could be personalized with help from Centro Stile and the Ad Personam program, making the series even more exclusive. The Roadster belongs to the model’s brief Few-Off production window, alongside the FKP 37 coupé.

Evolution

The 2020 Roadster represents the Sián in its most open form. Compared with the coupé, the key difference is the absence of a fixed roof, while the mechanical philosophy remains the same according to the dossier. Lamborghini quotes the same combined output of 819 hp, the same lightweight hybrid layout, and the same all-wheel-drive system. As a result, the car follows an experimental path in which the changes are focused more on body style and driving experience than on mechanical redesign. It also keeps hallmark Sián features such as rear-wheel steering and the Y-shaped lighting signature.

Variants

Within the Sián range, the 2020 Roadster differs from the Sián FKP 37 coupé through its open bodywork and an even smaller production run limited to 19 units. Both versions share the naturally aspirated 6.5-liter V12, the 48-volt electric motor, the supercapacitor, and the quoted total output of 819 hp. The distinction therefore lies mainly in body architecture and exclusivity. The dossier also notes that each car could be configured individually with Lamborghini Centro Stile and Ad Personam, which makes direct visual comparisons between examples difficult.
