After two images were released two days ahead of the 2012 Geneva Motor Show, Lamborghini has officially debuted the Aventador J, but not in concept form as previously suggested. The J is a fully functional sports car ready for road use. The bad news is that this will just be a one-off model that will ride off into the sunset with its new owner at the end of the Geneva Auto Show. "There is only one of them, no prototypes and no others for the Lamborghini Museum. The buyer can look forward to a truly unique, street-legal work of art."

The Aventador J is not the first one-off model offered by Lamborghini. This tradition began back in the 1970s with the unveiling of the one-off Jota - a Lamborghini Miura with improved performance and virtually redesigned in every detail. The car takes its "J" letter from the sporting rules of the FIA world motorsport organization: "Appendix J" defines the technical specification of race cars in the various classes.

The Aventador J’s exterior and interior meld into each other in an attempt to obtain a two-seat sport-bike effect. Elements like the climate control and nav systems have been removed in order to make the car faster. High quality materials also help in the speed department. Carbon fiber has been used for the car’s bumpers, the front air scoop, the winglets, and for that huge rear diffuser. Inside, the sports car boasts of seats covered in a new carbon fiber fabric called "Carbonskin."

Just like the standard Aventador, the one-off J version will be powered by a 6.5-liter V12 engine that is capable of delivering a total of 700 HP. Top speed goes up to an impressive 186 mph - a little less than the standard Aventador, but the J has to take into account it’s missing roof.

UPDATE 03/15/2012: There’s no doubt that the Aventador J had an impressive presence at the 2012 Geneva Motor Show, but how long did it took to create such a masterpiece? A year, half a year, a month, a few months? In an interview with Top Gear, designer Filippo Perini admitted that the Lamborghini team only needed six weeks: "It was the 14th of January that Mr Winkelmann asked us to do something for Geneva," says Perini. "A blank sheet. Do what you want. I drew up this car in a weekend..." Absolutely amazing!

UPDATE 04/22/12: For a car that was built for one customer, Lamborghini really spared no expense in the Aventador J. So much so that they even made a promo film for it. Check it out by clicking on the photo above.

Despite the fact that this one-off model carries the Aventador name, it is very different from the coupe version. The most obvious difference is the fact that there’s no roof, but the monocoque also has a new design, with a large windshield and two safety bars behind the seats. The decision of dropping elements like the air conditioning system and the navigation system make the car even faster.

Every part of the car has been redesigned in order to make every mile the owner spends behind the wheel an entertaining experience. The car measures 4890 mm long, 2030 mm wide, and 1110 mm tall. The classic front windshield has been replaced by two small wind deflectors and the rear view mirror is perched on an arm like a periscope.

Compared to a standard Aventador, the J’s front is somewhat narrower and is dominated by a highly distinctive carbon fiber air scoop, with central fixing braces and upward tilting winglets on the outer edges. At the rear, the vehicle gets a carbon-fiber rear diffuser, four huge tail pipes, rear lights with the typical Lamborghini light signature in the form of a Y, and an enormous fixed spoiler mounted on the bodyshell by two arms. There are also special, new front and rear bumpers that have been supplemented with carbon fiber fins that act as flow deviators. Their purpose is to achieve a significant increase in the vehicle’s downforce at both the front and the rear.

The Aventador J is painted in a very cool red developed specifically for this Aventador. That paint is combined with black carbon fiber parts and a new set of aluminum wheels - 20" at the front and 21" at the rears - with an additional carbon fiber insert that functions like a small fan for optimum brake ventilation. The doors also open upward and are considerably thinner than on the Aventador.

The Aventador J was designed in such a manner that the exterior and the interior give the impressive of being just one unit: a red stripe runs from the front hood, between the two wind deflectors, over the dashboard, down the console to the center tunnel, and back up between the seat backs. From there, it goes out again to the engine cover panel.

Lamborghini has dropped elements like the navigation system and the audio system so that the only elements remaining are a small control panel housing the starter button and the switches for lights and transmission. The seats and the cockpit are made from a carbon fiber fabric called "Carbonskin" - an element made of woven carbon fibers soaked with a very special epoxy resin that stabilizes the fiber structure and keeps the material soft. All of these features, or lack thereof, contribute to the speed of the Aventador J.

The Lamborghini Aventador J is powered by the same 6.5-liter V12 engine found in the standard Aventador. This engine is capable of delivering a mind-boggling 700 HP. However, despite it being a lighter model, Lamborghini has decided to drop the top speed from 217 to 186 mph to keep those safety standards at a quality high.

No prices have been announced for the Lamborghini Aventador J, but considering it is a one-off model, the one lucky owner should expect to pay more that $1 million for it.

When it comes to competition, it will be a little difficult to find a model as impressive suitable of taking the reigns from a car like the Aventador J. There are plenty of other open top two-seaters out there, but none come close to the power of Lamborghini’s special one-off J. The closest we found is the Ariel Atom V8 500, which delivers 500 HP - 200 HP less than the new J model. That being said, the Atom only costs $225,000 - making it more affordable than the new Lamborghini model. Then there’s the fact that it is not a one-off.

I can’t enjoy this as much if this gets common.

  (402) posted on 06.29.2012

I might be the only selfish person to actually like its exclusivity.

  (415) posted on 06.28.2012

Choosing Lamborghini Aventador J is a must. You’re such a lucky guy if that happens since that this Aventador is exclusively marketed in the market, and at the same time this will gain success to company since it has an expensive price tag.

This one is my favorite, along with Ferrari’s Berlinetta. They’re both stylish and powerful.

It’s highly respectable. I’m sure they’re going to love this too. It has unconventional design that car seekers won’t find any more reason to find other luxury+sports+compact car. 

  (502) posted on 05.29.2012

I’d want to be unique too, if ever I’d have this car. The exclusivity, however, is already quite a large number though.

  (428) posted on 05.18.2012

Upon its announcement, I just knew that I would love this supercar; the own belief has been strengthened once I’ve seen how dangerously edgy its exterior appearance is.

  (474) posted on 05.15.2012

It’s too bad that there’s still something more powerful and speedier than this, but it doesn’t mean that it’s not a great supercar anymore; its specifications remain astonishing, even its unbeatable unique and fierce appearance.

  (434) posted on 05.14.2012

Maybe the drop of its top is the main reason why its speed has decreased in figures; the resistance of Aventador J’s rate probably declined because of that. It has affected that aspect, but in return, its look became fierce further.

  (427) posted on 04.24.2012

This is second best to me. Even so, it’s undeniable that it is immensely dynamic. From its external design, you can already tell that its style is vicious.

  (427) posted on 04.19.2012

Its fierce beauty lies on its contours and edges. It’s even more stunning as you see it perform smoothly.

  (445) posted on 04.17.2012

I love this car to bits; I can’t find a single flaw, except maybe when they release its price.

  (570) posted on 04.16.2012

The price is beyond reasonable for its specifications. If I were to judge it, the accentuated edges are its attraction.

  (444) posted on 04.13.2012

One particular feature of this has captured my interest, and it is the jagged outline.

  (296) posted on 04.12.2012

It doesn’t matter if the changes are barely noticeable; it still looks as stunning as ever. You’d be more astounded if you’d see it on the run.

  (595) posted on 04.12.2012

As soon as I saw this, I didn’t feel the need to look on other supercars anymore. I’m contented on everything it has.

  (580) posted on 03.30.2012

I want to see this one personally. I’m deeply attached to its edgy appearance and breakthrough performance.

  (428) posted on 03.28.2012

Even if a lot of critics speculate that Enraged is more advantageous, I prefer this supercar more. Its aggressive appearance makes it unique and appealing to me. Its performance isn’t so bad either, yet it’s candidate for the best.

  (306) posted on 03.28.2012

The rough, jagged edges created a strong vibe of aggressiveness to this convertible. I don’t mind the minimal change in speed; I’m more thrilled of its enhanced dynamic performance.

  (401) posted on 03.22.2012

I have a love-hate relationship with this car. I like everything about it, but I’ll most likely loath its price tag.
