Lamborghini have officially taken the covers off their Lamborghini Aventador J Concept at the Geneva Motor Show 2012. As expected, it is a speedster version of the Lamborghini Aventador and not the Lamborghini Aventador Roadster that had been rumoured previously.
The Lamborghini Aventador J gets its name, rather bizarrely, from the sporting rules of the FIA world motorsport organization. Its “Appendix J” defines the technical specification of race cars in the various classes. The Lamborghini Aventador J gets the 6.5 liter V12 more commonly found in the Lamborghini Aventador LP700-4 with a 700hp power rating.
Weight for the Lamborghini Aventador J is just 1,575 kilograms, the same weight as the Aventador on which it is based. Whilst the design and the engine are hardly groundbreaking. The Aventador J uses a new type of carbon fibre construction. This carbon fiber fabric called “Carbonskin” is made of woven carbon fibers soaked with a very special epoxy resin that stabilizes the fiber structure and keeps the material soft. It is fitted to various aspects of the cockpit, including the seats.
One unique aspect of the design is the rear-view mirror, floating in the drivers eyeline in the absence of any windshield. The front of the Aventador J is thinner than the Aventador and features a different design. The red colour was designed specifically for this car.
The Lamborghini Aventador J uses 20 inch rims at the front and 21 inch at the rear. They are five spoke, aluminium designs with center locks and carbon fiber inserts. Lamborghini have retained the trademark vertical-rise doors. The X shaped strut across the engine bay is structural to provide this extreme concept with more stability.
