The stunning new Lamborghini Aventador J Roadster, recently revealed at the Geneva Motor Show, is not just a concept car but now a real one-off production vehicle.

It’s one thing to create a convertible version of the gorgeous Lamborghini Aventador LP700-4, it’s another thing entirely to take off the roof and the windscreen, fitting two small wind deflectors in front of the driver and passenger compartments as well as removing climate control and navigation. What you do get, however, is what Lamborghini calls “an utterly indescribable experience of power and dynamics.”

In order to save eight, the auto manufacturer has used a new carbon fibre fabric called “Carbonskin” that is apparently soft and supple enough to be used on the seats and interior trim.

Sold for the price of 2.1 million Euros, the Aventador uses the same 700-horsepower, 6.5-litre V12 as its hardtop kin” and Lamborghini states that the open-air J will reach speeds as high as 186 miles per hour.”

Stephan Winkelmann, President and CEO of Automobili Lamborghini said “The new Lamborghini Aventador J is the most radical open supersports car of Lamborghini’s history. Its name comes from our tradition and combines an unconventional design with technology innovation.”
