The Lamborghini Sián Roadster asserts the futuristic design of the coupé, but as a true roadster adds a new purity with the open-air cabin. The aerial view of the 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 Sián’s long sculptured contours and characteristic aero wings give the Sián Roadster an unmistakably powerful profile. The car’s very low front, with integrated carbon fiber splitter, houses the iconic Lamborghini Y-shape headlights.
The pure and uncluttered Sián design is a clear statement of the car’s optimized aerodynamic efficiency and technological prowess: airflow is directed through the front splitters and through the front bonnet, through the side air intakes and outlets and over the rear spoiler, with no loss of aerodynamic efficiency from the roadster’s roofless design. Active cooling vanes on the rear use 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.
