Meet a new Aventador

GENEVA: Lamborghini has turned the Aventador into a roadster.

It's off with the top and the front windshield for the Aventador J. This requires that drivers of the one-off car must have the right equipment for driving at speeds higher than 300kph.

The letter J is derived from the sporting rules of the FIA world motorsport organisation. Its “Appendix J” defines the technical specification of race cars in the various classes.


The technical basis for the Aventador J is the Aventador LP 700-4, Lamborghini’s new twelve-cylinder model.

The Lamborghini Aventador LP 700-4’s technology package is unique – its structure is based on an innovative monocoque made from carbon fiber reinforced polymers that combines systematic lightweight design with optimum stiffness and safety.

The new twelve-cylinder with a displacement of 6.5 litres and 700 hp combines the best in high-revving thrills with mighty pulling power. It uses a super-fast ISR transmission, permanent all-wheel drive and push-rod suspension.

Virtually every part of the Aventador JAventador J outer chassis was redesigned. The car’s overall length is 4890 mm, the width (excluding mirrors) is 2030 mm while the height is 1110 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 superbike rider – therefore the right clothing is prerequisite for every trip.

A carbon fiber fabric called “Carbonskin” is used for the first time in this car. It's made of woven carbon fibers soaked with a special epoxy resin that stabilizes the fiber structure and keeps the material soft.


Like a hi-tech fabric, the carbon fiber mats fit neatly to every shape. In the Aventador J, the complete cockpit and parts of the seats are clad in this material and shimmer in matt carbon fiber 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 front of the Aventador J is somewhat narrower than that of the Aventador. The front end is dominated by a highly distinctive carbon fiber 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 like a Formula 1 racing car.

The wheels were also developed specifically for this car, with 20-inch rims at the front and 21-inch at the rear. The five-spoke aluminum wheels have a central lock system and an additional carbon fiber insert that functions like a small fan for optimum brake ventilation.

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.

Because of its ample dimensions, the eye is drawn inexorably to the rear end. It consists in principle of just three elements – the carbon-fiber 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 bodyshell by two arms.

Only one person in the world will get to own this car following the end of the Geneva Motor Show.
