Representing the pure expression of the brand’s DNA, the Aventador J is an extreme and uncompromising concept-esque roadster and a technology showcase, demonstrating the use of new materials and the company’s expertise in carbon fiber technology.
The technical basis for the Aventador J is the Aventador LP 700-4 with its structure based on a monocoque made from carbon fiber reinforced polymers.
The car is powered by the same engine of the base model, a 6.5 liters twelve-cylinder unit with 515 kW / 700 hp, coupled with ISR transmission, permanent all-wheel drive and pushrod suspension.
The Aventador J was built as a one-off which has already been sold for 2.1 million Euros.
The radical exterior has no roof nor windshield – replaced by two small wind deflectors – so both the driver and the passenger need to wear a helmet on every trip.
The letter J is derived from the sporting rules of the FIA world motorsport organization – the Appendix J defines the technical specification of race cars in the various classes.
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.
The front end is narrower than that of the Aventador, and features a distinctive carbon fiber air scoop, with central fixing braces and upward tilting winglets on the outer edges, which reminds of a Formula one car when seen from the side.
The doors open upward – as on the Aventador 700-4 – are thinner and integrated tiny, fixed side windows.
The rear end consists of three main elements: the carbon-fiber rear diffuser, the four huge tail pipes and the rear lights with their typical Y-shaped signature.
The remaining surface area is for heat dissipation and is enclosed only by a black metal mesh.
The massive spoiler is mounted on the bodyshell by two arms, which are also directly connected with the diffuser, another racing-inspired element.
In comparison with the Aventador LP 700-4, the exclusive Aventador J has specific front and rear bumpers, which integrate carbon fiber fins that act as flow deviators, which allow to achieve increased downforce at both the front and the rear.
The five-spoke aluminum wheels, developed specifically for this car, are 20-inch in size at the front and 21-inch at the rear.
They have a central lock system and an additional carbon fiber insert that functions like a small fan for optimum brake ventilation.
The Aventador J’s exterior and interior forms flow seamlessly into each other, as underlined by the red stripe that 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, before leaving the interior and heading for the engine cover panel.
This band of color connects the front and the rear of the car, creates 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 interior is essential and focused on the driving experience. There are no navigation, car audio system, associated screen or air conditioning controls.
The seats are made of Forged COMPOSITE, with inserts of flexible carbon fiber fabrics, a technology patented by Lamborghini.
The company has also developed a new carbon fiber fabric called Carbonskin, made of woven carbon fibers soaked with a very special epoxy resin that stabilizes the fiber structure and keeps the material soft.
On the Aventador J, this material is used on the complete cockpit and parts of the seats, and there are many potential uses in the future.
