18th March, 2012
At Switzerland's 2012 Geneva Motor Show, Lamborghini presented its most
uncompromising open super sports car ever.
The Lamborghini Aventador J is a force of nature on wheels – supremely powerful and supremely open. The Aventador J
offers its driver and passenger an experience that is said to be utterly indescribable. At the same time, the 515 kW (700
hp) two-seater is a first class technology showcase, combining innovative solutions and brand new materials and
demonstrating Automobili Lamborghini’s enormous expertise in carbon fibre technology.
The Lamborghini Aventador J is a radically open automobile – exterior and interior meld into each other. The designers
and engineers in Sant’Agata Bolognese (Italy) have not only dispensed entirely with the roof, but also with the front
windshield. This requires that drivers of the Aventador J must have the right equipment for driving at high speeds.
This kind of driving at the limit is a highly exclusive experience – the Lamborghini Aventador J is fully functional
for road use. It is an absolute one-off.
“With the Lamborghini Aventador J, we have moulded our brand 'DNA' into its most definitive form to date. This
automobile is as extreme and as uncompromising as only a Lamborghini can be,” says Stephan Winkelmann, President and
CEO of Automobili Lamborghini. “The new Lamborghini Aventador J is the most radical open super sports car of
Lamborghini’s history. Its name comes from our tradition and combines an unconventional design with technology
innovation. Nowadays we are confronted with several regulations that we face in the spirit of challenge. The Aventador J
is the proof that, despite the rules, Lamborghini will always make people dream, even in the future.”
Continuation of a glorious tradition
With the Aventador J, technically based on the Aventador, Automobili Lamborghini is carrying on its glorious brand
tradition. The 1970 Jota, for instance, was the stuff of legends – a Lamborghini Miura with improved performance and
virtually redesigned in every detail. It remained a one-off; although some owners subsequently had their Miuras modified
to look like the Jota.
The letter J is derived from the sporting rules of the FIA world motor sport organisation. Its “Appendix J” defines the
technical specification of race cars in the various classes.

The Aventador: Extremely open, overwhelming power
The Lamborghini Aventador J is a super sports car of positively dramatic single-mindedness and openness. It combines
the overwhelming performance of the Lamborghini Aventador with the most intense experience of power and dynamics
imaginable in an automobile.
The technical basis for the Aventador J is the Aventador LP 700-4, Lamborghini’s new twelve-cylinder model. Presented
in 2011, the Aventador has been acclaimed by customers. The Lamborghini Aventador LP 700-4’s technology package is unique
– its structure is based on an innovative monocoque made from carbon fibre reinforced polymers that combines systematic
lightweight design with optimum stiffness and safety. The new twelve-cylinder with a displacement of 6.5 litres and 515
kW (700 hp) combines the best in high-revving thrills with mighty pulling power. Its super-fast ISR transmission,
permanent all-wheel drive and push-rod suspension combine this potent power with the utmost handling precision.
Systematic lightweight design – considerable weight reduction
Naturally, the Aventador J benefits enormously from this unique technology package. Yet the Aventador J has a
significantly different interpretation to the Aventador coupé. In this open version, the monocoque has a largely new
design, including the two safety bars behind the seats. The absence of a roof, of the large windshield, of the air
conditioning system and of the navigation system obviously takes it to an even lower weight. With a dry weight of 1,575
kilogrammes, the series production Aventador LP 700-4 is already extremely light for its performance class thanks to its
carbon fibre construction.
Carbonskin, a brand new carbon fibre material
The unique expertise of Automobili Lamborghini in the field of carbon fibre reinforced polymers is evident not only in
the hi-tech monocoque, but also in the research into further innovative solutions. Unlike traditional seats, in the
Aventador J seats are made of Forged COMPOSITE®, with inserts of flexible carbon fibre fabrics: a result of an innovative
Lamborghini have developed an even more amazing version of carbon fibre material for the Aventador J. In its first
automotive application, this carbon fibre fabric called “Carbonskin” is made of woven carbon fibres soaked with a very
special epoxy resin that stabilises the fibre structure and keeps the material soft. Like a hi-tech fabric, the carbon
fibre mats fit perfectly to every shape. In the Aventador J, the complete cabin and parts of the seats are clad in this
material and shimmer in matt carbon fibre black. It’s conceivable that in future there will be many potential
applications for this freshly patented and extremely fine-looking material, even very high-end clothing.
The Design: uncompromisingly Lamborghini
An extreme Aventador obviously needs an equally single-minded design, which goes without saying at the Centro Stile
Lamborghini. Every single model from Sant’Agata Bolognese bears the unique design of the brand. Clear, precise surfaces,
as well as sharp, often broken lines are among the unmistakable styling tools. They consistently emphasise the power and
enormous presence of these Italian super sports cars. Not one line is ever accidental – the defining principle is always
‘form follows function’.
This function is very clearly defined for the Aventador J – explosive dynamics, extreme driving fun, a unique
experience. Every kilometre with the Aventador J is extreme fun: something plainly evident from the very first glance.
Rear view mirror like a periscope
Virtually every part of the outer chassis was redesigned for the Aventador J, yet it shows the spirit of Lamborghini
in its most concentrated form. The car’s dimensions are extreme: the overall length is 4,890 mm, the overall width
(excluding mirrors) is 2,030 mm while the height is 1,110 mm.
The highest points are marked by the rear view mirror, which is perched on an arm like a periscope, and by the two
safety bars behind the seats. In place of the classic front windshield there are two small wind deflectors. The occupants
of the Aventador J are confronted by the element of the wind in much the same way as a super bike rider – therefore the
right clothing is prerequisite for every trip.
Front scoop with winglets
The front of the Aventador J is somewhat narrower than that of the Aventador. The front end is dominated by a highly
distinctive carbon fibre air scoop, with central fixing braces and upward tilting winglets on the outer edges. Viewed
from the side, the front end of the Aventador J looks, in a way, similar to a Formula 1 racing car.
Red with chrome effect, wheels with CFRP fan
The black of the carbon fibre parts is visibly evident throughout the car – the significantly wider sill elements and
the mighty rear diffuser form a perfect contrast to the rich red body paintwork. The special red colour was developed
specifically for this Aventador - a highly intensive red with a slight chrome effect.
The wheels, of course, were also developed specifically for this car, with 20-inch rims at the front and 21-inch at
the rear. The five-spoke aluminium wheels have a central lock system and an additional carbon fibre insert that functions
like a small fan for optimum brake ventilation.
Naturally, the doors on the Aventador J also open upward. They are considerably thinner than on the Aventador and are
fitted with a tiny, fixed side window. The 'muscular' flanks around the rear wheels are hallmark Lamborghini styling
Rear end purely for aerodynamics and ventilation
Because of its ample dimensions, the eye is drawn inexorably to the rear end. It consists in principle of just three
elements – the carbon-fibre rear diffuser, the four huge tail pipes and the rear lights with their typical Lamborghini
light signature in the form of a Y. The remaining surface area is for heat dissipation and is enclosed only by a black
metal mesh. The rear end is crowned by an enormous fixed spoiler mounted on the body shell by two arms. ‘Form follows
function’ to the nth degree. The spoiler is supported by two pillars connected by the diffuser: clearly inspired by
In comparison with the Aventador LP 700-4, the exclusive Aventador J has special bumpers at the front and rear. Both
bumpers have been supplemented with carbon fibre 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 outside comes inside
The Aventador J’s exterior and interior forms flow seamlessly into each other. This super sports car turns its inside
outward and is as open as it can possibly be. Conversely, the exterior ‘flows’ through the interior – a red stripe runs
from the front bonnet, between the two wind deflectors, over the dashboard, down the console to the centre tunnel and
back up between the seat backs, before leaving the interior and heading for the engine cover panel.
Interior is minimalist and single-minded
This band of colour connects the front and the rear of the car, provides a visual separation between the driver and
passenger space and is interrupted only by a small control panel housing the starter button and the switches for lights
and transmission. The Aventador J is equipped neither with a navigation nor car audio system, nor does it have the
associated screen or air conditioning controls – these would simply detract from its one and only raison d’être as an
extreme driving experience. What remains, of course, are two programmable TFT displays behind the steering wheel.
The engine cover also brings the inside to the outside. To be more precise, it is not so much a cover but more a
framework. This part has a new geometry (X shape) and is made of carbon fibre. Two large openings lay bare both cylinder
banks of the mighty V12 power unit with its 6.5 litres of displacement – a truly stunning sight for every automobile
A unique work of art licensed for the road
However, following the Geneva Motor Show, this sight will be the preserve of just one – the future owner of the
Lamborghini Aventador J. 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. He/she will possess the most extreme expression of Lamborghini
DNA in existence and a real masterpiece of high technology. But other enthusiasts of the super sports cars from Sant’
Agata Bolognese can rest assured - the Aventador success story has only just begun.
