Ahead of its official 2013 Geneva Motor Show debut, images have leaked of Lamborghini’s latest supercar. The Veneno Roadster is obviously a topless version of the Veneno coupe, which is itself mostly based on the Aventador and its firebreathing 6.5-litre V12 engine. Tuned to generate a blurry-eyed 740 horsepower, the Veneno Roadster’s open-top design is the only thing that separates it from its AWD coupe brethren — that and the fact that 9 will be built, as opposed to only 3 of the coupe (all of which are already claimed). The version above features a Rosso Veneno paintjob created specifically for the Roadster, which is heavily outfitted with carbon fiber parts. Its futuristic razorblade front end and rear diffuser are obviously purpose-driven, lending the car an incredible downforce to keep all its four wheels on the asphalt. Which is necessary, given Lambo’s claimed 0-62 mph time of 2.9 seconds and top speed of 221mph. The Roadster supercar also features carbon-ceramic disc brakes, a seven-speed “ISR” transmission, AWD, a re-configurated racing chassis and bespoke alloy wheels. Exactly how much for all this madness? Oh, just about $4.5 million (3.3 million Euros) — making it the most expensive “production” car in the world.
