Nearly two years after Lamborghini introduced the Aventador LP700-4 at the 2011 Geneva Motor Show, its topless counterpart has now been revealed. The Aventador LP700-4 Roadster, "the most exciting series production Lamborghini ever built and the new benchmark in the world of open-top luxury super sports cars."
The difference between the hardtop Aventador and the roadster can immediately be seen in the unique profile of its upper area, which extends along newly designed geometric lines from the removable roof to the engine hood.
The two-piece roof is made entirely from carbon fiber using various technologies that guarantee maximum aesthetic performance and stiffness, with each component weighing less than 6kg. Lightweight, removable, easy to handle, and simple to attach, the two parts can be stored in the front luggage compartment.
The rear pillar, meanwhile, has been redesigned to offer total support for the removable roof, accommodate an automatic protection system for passengers, and provide the engine compartment with ample ventilation.
Another item that differentiates the Aventador Roadster from the coupe is that the engine hood of the former has a central "spinal column" with two pairs of hexagonal windows connected at the sides, which cool the engine, drain off rainwater properly and "allow the beauty of the V12 power unit to be admired."
For its cabin, the Aventador Roadster has a powered rear windshield that not only influences the flow of air in the vehicle but also controls the experience of the sound from the 12-cylinder engine. A wind deflector, meanwhile, delivers almost complete calm inside the car even at high speed. Its door windows also have chamfered edges to ensure a perfect fit into the hardtop seal.
Powering the Aventador Roadster is the same 6.5-liter V12 engine in the coupe. Together with its seven-speed semi-automatic transmission and push-rod suspension, it can run the 0-to-100kph sprint in three seconds before reaching a maximum speed in the vicinity of 350kph.
The Aventador Roadster also features the Italian carmaker's new fuel-efficiency systems that were only announced last September, including a cylinder deactivation system that functions when the engine is only working at partial load, and a start/stop system that powers up the engine in just 180 milliseconds.
