Lamborghini Aventador J Revealed - Bring Your Helmets

Something only this bonkers could come from Lamborghini.

There's only one important fact that you need to take with you after reading this: Lamborghini will, in fact, sell the Aventador J. The latest bull to come through the gates of the Italian automaker's Sant'Agata Bolognese factory is making its official debut today at the Geneva Motor Show. And we have no doubt that it's already an instant classic. Yes, it's based off the Aventador which premiered last year at Geneva.

However, Lamborghini describes the Aventador J as an example of molding their DNA into its most definitive form to-date. According to CEO Stephan Winkelmann, the Aventador J is as "extreme and as uncompromising as only a Lamborghini can be. It is the most radical open super sports car of Lamborghini's history." Power still comes from that wonderful 6.5-liter V12 with 700hp that's mated to an ISR transmission sending power to all four wheels. So where does the name "J" come from? According to Lamborghini, the letter J is derived from the sporting rules of the FIA world motorsport organization.

Its "Appendix J" defines the technical specification of race cars in various classes. Clearly, the J is based on the Aventador, but it's a significantly different interpretation. For starters, the already advanced monocoque has a new design, including the two safety bars behind the seats. With the absence of a roof, windshield, air conditioning and navigation systems, weight has been further decreased from that of the coupe. However, thanks to the J's new "Carbonskin", weight is cut even further. Being used for the first time, this unique "skin" is made of woven carbon fibers soaked with a very special epoxy resin that stabilizes the fiber structure.

In turn, this keeps the material soft, allowing it to mold perfectly to every shape. For the Aventador J, the entire cockpit and parts of the seats are clad in this material, paving the way for future applications of this latest technology. In terms of exterior design, every part of the Aventador's outer chassis has been redesigned. The front is a bit narrower than that of the standard Aventador and it has a distinctive carbon fiber air scoop with central fixing braces and upward tilting winglets on the outer edges. Lamborghini claims that from a side view, the Aventador J looks like a Formula 1 racing car.

The rear end is also unique, consisting of only three elements: the carbon fiber diffuser, the four tail pipes and the rear lights. The rest of the surface are is for heat dissipation and is enclosed with a black metal mesh. The large racing inspired rear spoiler is mounted onto the bodyshell by two arms. In addition, the Aventador J has special front and rear bumpers supplemented with carbon fiber fins with the purpose to achieve a significant increase in downforce. It rides on five-spoke aluminum 20-inch rims up front and 21-inchers out back.

Even the trademark scissor doors are considerably thinner compared to the standard Aventador's and are fitted with a tiny, fixed side window.

The minimalist interior has none of the creature comforts from the standard Aventador, as this car's sole purpose is to provide an extreme driving experience. As expected, the engine cover is also made of carbon fiber and has two large openings that proudly display that wonderful V12. The periscope-like rear view mirror sits in between two small wind deflectors as occupants are meant to have the experience of a super bike rider. Lamborghini suggests proper attire is a prerequisite for every trip, considering its top speed is more than 186 mph.

The automaker hasn't given any specific time frame as to when the Aventador J will go on sale (not to mention pricing), but word is that this is going to be a one-off. So is this the most insane Lamborghini ever built? Quite possibly and the automaker claims that this is only the beginning of the Aventador success story.
