EXTERIOR

The futuristic Lamborghini design features long, sculptured contours and distinctive aero wings to define a commanding and powerful profile, a shape that is pure and purposeful. The very low front, enhanced by an integrated carbon fiber splitter and the iconic Lamborghini Y-shaped headlights, optimizes aerodynamic efficiency, for a sensation perceptible from within the open-air cabin.

INTERIOR

Lamborghini elevates the design of its hybrid cars with sophisticated aluminum details painted in Oro Electrum (gold), the color Lamborghini has chosen to identify it’s hybrid cars. The purposeful interior of the Sián Roadster embraces this elegant effect with Y-shaped features and distinctive hexagonal accents harkening back to the first Lamborghini Miura. Every touch reflects meticulous attention to detail, from the driver controls to the newly designed air vents produced by special 3D printing, a technology that allows a customer’s initials to be incorporated into the vent design.

Driving Dynamics

MOTOR/IC ENGINE

The Sián Roadster sports Lamborghini’s innovative supercapacitor application: a world-first technology storing ten times the power of a lithium-ion battery.

Driving Dynamics

SMART MATERIALS

Active cooling vanes on the rear are made with unique materials-science technology patented by Lamborghini.

Driving Dynamics

4-WHEEL STEERING

The Sián Roadster offers a unique combination of the active steering system (Lamborghini Dynamic Steering) and the rear-steering system (Lamborghini Rear-wheel Steering), delivering maximum dynamic performance.

Driving Dynamics

4-WHEEL DRIVE

The 4-wheel-drive system on the Sián Roadster is optimized to work specifically with the new active systems, in particular rear-wheel steering.

Driving Dynamics

4 ACTIVE SUSPENSION

The Sián Roadster features magneto-rheological front and rear shock absorbers with pushrod systems, which constantly modify suspension behavior according to the road conditions and the selected driving mode.

MOTOR/IC ENGINE

The Sián Roadster sports Lamborghini’s innovative supercapacitor application: a world-first technology storing ten times the power of a lithium-ion battery. Three times more powerful than a battery of the same weight and three times lighter than a battery producing the same power, the electric system with the supercapacitor and 34 CV e-motor weighs only 34 kg, thus delivering a remarkable weight-to-power ratio of 1.0 kg/CV. The indomitable V12 engine of the Sián Roadster incorporates titanium intake valves and is uprated to 785 CV (577 kW) at 8,500 rpm, thus becoming the most powerful Lamborghini engine ever made, delivering a total of 819 CV (602 kW) and reaching a top speed of over 350 km/h.
 

SMART MATERIALS

Active cooling vanes on the rear are made with unique materials-science technology patented by Lamborghini. Operation of the vanes is triggered by the reaction of smart-material elements to the temperature generated by the exhaust system, causing them to rotate and providing an elegant and lightweight cooling solution.

 

4-WHEEL STEERING

The Sián Roadster offers a unique combination of the active steering system (Lamborghini Dynamic Steering) and the rear-steering system (Lamborghini Rear-wheel Steering), delivering maximum dynamic performance. The LDS system adapts to the speed and the selected driving mode, moving between direct steering and a more indirect mode, while the LRS system manages the rear-steering axle through two electromechanical actuators. This system improves agility at low speeds, while providing optimum vehicle control and greater stability at highway speeds.

4-WHEEL DRIVE

The 4-wheel-drive system on the Sián Roadster is optimized to work specifically with the new active systems, in particular rear-wheel steering. This system is able to maximize performance and driving pleasure in poor grip situations. Here, torque distribution between the front and rear axles is varied dynamically in real time depending on the selected driving mode and the driving conditions. Additionally, the Sián Roadster makes use of a brand-new Pirelli P Zero Corsa tire design, specifically developed to further enhance the vehicle’s active driver-assistance systems.

4 ACTIVE SUSPENSION

The Sián Roadster features magneto-rheological front and rear shock absorbers with pushrod systems, which constantly modify suspension behavior according to the road conditions and the selected driving mode. In addition to compensating for roll and undesired movements of the vehicle body, the system is specifically designed to work in concert with the rear-wheel steering system, thus ensuring an ideal response under all conditions.
