At the heart of the Lamborghini Aventador Roadster is the same V12 6.5-liter normally-aspirated engine that features a stop/start system, cylinder deactivation, and is connected to a 7-speed automatic transmission – all of which allows for 0-62 mph (0-100 km/h) capabilities in three seconds on its way to a top speed of 217 mph (349 km/h). In addition, the engine cover now features a “spinal column” with two lines of hexagonal windows – while the scissor doors have a chamfered edge for the frameless windows. Unlike its Murcielago Roadster predecessor which featured a fabric roof, the Aventador features a carbon fiber version that uses Forged Composite technology and can be easily removed in but a few seconds. Some of the Roadster-exclusive amenities include 20 and 21-inch (front/rear) alloys that lower the vehicle’s weight by 10 kg (22 pounds) – along with a bespoke two-tone finish. The 2013 Lamborghini Aventador Roadster will go on sale next summer at a starting price of €300,000 EUR (approximately $382,000 USD).
