Lamborghini Sián Roadster | Lamborghini Montreal

OVERVIEW

The first open-top hybrid Lamborghini super sports car to feature a supercapacitor, the Sián Roadster roars with electrified intensity, resonating with the inimitable V12 sound from the most powerful Lamborghini engine to date. Limited to only 19 examples, the Sián Roadster advances hybrid technology with the world’s first use of a supercapacitor in a materials-science application unique to the industry.

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.

Electric Engine/Internal Combustion Engine

DRIVING DYNAMICS

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

DRIVING DYNAMICS

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

DRIVING DYNAMICS

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.
4-Wheel Drive System

DRIVING DYNAMICS

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

DRIVING DYNAMICS

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.
