Currently reading: Geneva motor show 2012: Lambo Aventador J
The Lamborghini Aventador is a road-legal roadster which pushes the limits of design

This is the Lamborghini Aventador J, a one-off, road-legal roadster that company boss Stephan Winkelmann says is a testament to his firm’s commitment to pushing the limits of design, despite increasingly rigid road car regulations.

As such, it takes its name from the world motorsport governing body’s ‘Appendix J’ regulations, which define racing car class specifications. The J also invokes Lamborghini’s history, referencing the one-off 1970 Lamborghini Jota, which was a high-performance version of the legendary Miura.

The roofless roadster took centre stage on the firm’s Geneva motor show stand and has already been sold off at an undisclosed price as “the most extreme expression of Lamborghini DNA in existence”. It is priced at €2.1million, or about £1.75m.

Lamborghini has pledged that no other prototypes or museum pieces will be made in the same vein — although insiders have confirmed that a more widely available but less extreme Aventador roadster will be launched later this year.

Modifications are restricted to the J’s extreme styling; it’s powered by the same 690bhp 6.5-litre V12 as that of the fixed-head car. It also has the same four-wheel drive system and uses a modified version of the same pushrod suspension.

The J is based on the Aventador’s carbonfibre monocoque, although it has been extensively modified to accommodate the roofless structure, as well as being stripped out in the interests of saving weight. The bodywork has also been substantially reworked to boost aerodynamic grip.

The loss of the roof, windscreen, air-con, stereo system and sat-nav mean the Aventador J is significantly lighter than the coupé; Lamborghini says the interior has been stripped out, as any gadgets would detract from the “raison d’etre of this car: to provide an extreme driving experience”. It also features upward-opening doors that are substantially thinner and lighter than the coupe’s. Lamborghini has not released its weight, however.

At 4900mm in length, 2030mm wide and 1110mm high, it is 120mm longer and 26mm lower than the Aventador coupé; the width is the same, but Lamborghini says this is the lowest car it has ever built. Despite the absence of a windscreen, the height difference isn’t as great as you might expect due to the protruding rear-view mirror, which sits on a periscope-like arm, and the two rollover bars that sit behind the seats.

The front end is also narrower than that of the fixed-head Aventador and features a dramatic air scoop with central fixing braces and upward-tilting winglets on the outer edges. Lamborghini claims these, plus the substantial rear spoiler, have been designed to give the Aventador J the look of a Formula 1 racing car.

At a preview to the new car at the Volkswagen Group night ahead of the Geneva motor show, Lamborghini boss Stephan Winkelmann said, "at Lamborgini we make dreams come true and we want to continue doing this in the future".

Re: Geneva 2012: Lambo Aventador J

there's some speculation as to why Lamborghini are producing only one of these, and why it's not being retained by them as a musem piece.

IMO the only reason can be that it's been commissioned by an individual for their own collection / use. Could there be any other significance of the "J" nomenclature? a certain Mr J Leno for example?

It's being reported elsewhere that the Aventador J is already sold. This makes me wonder whether it was built to order, hence why there's only one and Lamborghini aren't keeping it.

A lesson for Aston Martin, this is how you do 'exclusive'.
Ha, ha, quite. And if this goes for £2m for a one-off as spectacular as this it makes the £1.4m for one of 77 look even more silly than it already does. Poor Aston Martin - they really didn't judge that one well, did they. Do you think they'll upset as many people as Jaguar did with the XJ220 when the bottom fell out and it was exposed for the cynical bandwagoning that it was?

From our lowly perspective (I make the assumption that none of us here are in the market for cars of this price) it does seem the Aston Marton is not offering very good 'value for money' in terms of $ or £ per horsepower, but that misses the point.

In this market it's all about rarity and the fact that if you buy 10 of these (as I believe one arabian customer has done), you are in a class of one, any idea of 'value for money' simply has no meaning. if the customer doesn't spend his £1.4m on this he'll spend it on a yacht, or another house, or presents for his wives.

It's all about keeping one ahead of the Joneses (or the Al Maktoums, depending where you hail from), and getting something that they simply cannot have, no matter how much they spend (hence if you buy 10 you're effectively sticking 2 x 2 fingers up at them as i) "I bought 10, you didn't"; ii) "I bought 10 therefore there are fewer chances of you being able to acquire one")

In its defence Lesia, One-77 is infinitely better engineered than XJ220 ever could have been, given that the latter was really a super-kit-car dreamed up by a bunch of petrol heads on their Saturday mornings off and with no real budget.

For what it's worth, from my lowly perspective I wouldn't buy one either if I was spending my own money to that level, but that matters not two hoots to Aston Martin!
