The Lamborghini Aventador Roadster for 2013 makes for welcoming news with 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) at the core of the car. Additionally, the “spinal column” engine comes with two lines of hexagonal windows – while aesthetically the scissor doors have a chamfered edge for the frameless windows and features a carbon fiber version that uses Forged Composite technology.
