The hand-built Lamborghini Aventador J features a 6.5-liter V12 engine good for 700hp. The engine is mated to an ISR transmission delivering power to all four wheels. The Aventador J showcases Aventador styling, though it is characterized by the absence of a roof, windshield, air conditioning and navigation system. Thanks to these amputations, weight has been further decreased from that of the coupe. The aforementioned, ultra-light "Carbonskin" guarantees that weight is cut even further. Being used for the first time, this unique "skin" is made of woven carbon fibers.
