Lamborghini has unveiled the Sián Roadster. The limited-edition, open-top hybrid super sports car combines the firm’s iconic V12 engine with unique hybrid technologies for unsurpassed performance.
The roofless design puts an exclusive group of drivers in one of the most spectacular cockpits ever. Because it is always open, the V12 sound from the most powerful Lamborghini engine to date is certain to resonate in the cabin.
The aerial view of the Lamborghini Sián Roadster is evocative of the iconic periscopio line inspired by the first Countach, running diagonally from the cockpit to the rear and culminating in the aerodynamic airstreamers behind driver and passenger.
The car’s low front and integrated carbon fibre splitter directs airflow through the side air intakes and outlets and over the rear spoiler. Lamborghini says there is no loss of aerodynamic efficiency despite the roofless design.
The rear of the car meanwhile, incorporates Lamborghini’s evocative hexagon design into the taillights, also inspired by the Countach. The rear wing is integrated within the profile and extends out only during driving to enhance performance.
The Lamborghini Sián Roadster also sports the carmaker’s innovative supercapacitor. It is capable of storing 10 times the power of a lithium-ion battery. For perfect weight distribution, it is located in the bulkhead between cockpit and engine.
The electric system with the supercapacitor and e-motor weighs only 34kg, delivering a remarkable weight-to-power ratio of 1.0kg/bhp).
This advanced technology combines with the V12 engine, which incorporates titanium intake valves and is uprated to 774bhp at 8500rpm.
Combined with the additional 34bhp from the hybrid system, the Lamborghini Sián Roadster delivers a total of 808bhp and reaches a top speed of over 350km/h.
The innovative system delivers instant acceleration in low gears, allowing the car to accelerate from zero to 100km/h in less than 2.9 seconds.
