The Lamborghini Sian is the first hybrid supercar from Sant'Agata Bolognese, and it marks a defining moment in the brand's history. Named after the Bolognese dialect word for lightning, the Sian announces Lamborghini's entry into electrification not with a quiet footnote but with 819 combined horsepower and a sold-out production run of 63 coupes, all gone within 63 seconds of announcement.
What Powers the Lamborghini Sian?
The Sian shares its beating heart with the Aventador SVJ: a naturally aspirated 6.5-liter V12 producing 774 hp at 8,500 rpm, the highest output ever from a Lamborghini engine at the time of its launch. To that, a 48-volt mild hybrid system adds a further 34 hp via a compact electric motor integrated into the gearbox. Total combined output is 819 hp, making it the most powerful production Lamborghini built to that point.
The hybrid system uses a supercapacitor rather than a conventional lithium battery, a choice Lamborghini made because a supercapacitor is three times more powerful than a battery of equivalent weight and delivers instantaneous torque without delay. The technology provides enhanced response at low speeds, smoother gear shifts, and immediate torque vectoring to the rear wheels.
How Fast Is the Lamborghini Sian?
The Sian covers 0-100 km/h in under 2.8 seconds and is electronically limited to 350 km/h (217 mph). Those figures place it comfortably among the fastest production supercars ever made. The combination of the V12's high-revving character with the supercapacitor's instant torque fill creates a driving experience that Lamborghini describes as entirely new, even by Aventador standards.
Design: A 21st Century Countach
Lamborghini's design team drew on the Terzo Millennio concept while also referencing the sharp, theatrical lines of the brand's iconic 1980s supercars. The result reads as a contemporary interpretation of the Countach: forward-looking rather than retrospective, but unmistakably rooted in Lamborghini's visual language. The number 63 appears near the rear of the car, referencing both the number of units produced and Lamborghini's founding year of 1963. At $3.6 million per car, the Sian is one of the brand's most expensive offerings and one of its rarest.
