Well, here’s a very unique Lamborghini, truly a one-of-a-kind example. It’s called the Aventador J, and the folk at Sant’ Agata Bolognese are calling it the most uncompromising open super sports car in the company’s entire history.

The two-seater, technically based on the Aventador LP 700-4, dispenses entirely with the roof as well as the front windshield, not to mention air-conditioning and the navigation system, but the 700 hp machine is fully-functional for road use.

Created by Centro Stile Lamborghini, the car was conceived as a “barchetta,” so in place of the classic front windshield there are two small wind deflectors, which effectively makes it the lowest car ever made by the company. It also requires that the occupants must have the right equipment for driving the car at speed, if one values one’s face, that is.

The J suffix for this one 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, though the chosen alphabet is also an indirect homage to the one-off Jota of old.

The monocoque has a largely new design, including the incorporation of two safety bars behind the seats. While the doors on the J also open upward, they are considerably thinner than on the Aventador and are fitted with a tiny, fixed side window.

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

The car also features special front and rear bumpers; both have been supplemented with carbon fibre fins that act as flow deviators and help increase downforce. The front of the J is somewhat narrower than that of the Aventador, and 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.

Meanwhile, the interior is minimalist – there’s a small control panel housing the starter button and the switches for lights and transmission, as well as two programmable TFT displays behind the steering wheel.

Features include the use of Forged Composite parts, like on the bucket seats – Forged Composite is an innovative carbon fibre material which was used for the first time by Lambo in the Sesto Elemento monocoque. The seats are clad in a special, new carbon fibre-based textile called CarbonSkin, and represents the first application in a car.

The car, which is finished in a special, highly intensive red with a slight chrome effect, wears the same 6.5 litre 12-cylinder mill as found in the base car. After Geneva, where the car makes its premiere, the Aventador J is set to be the preserve of just one – its future owner. It’ll be the only one ever made, so the one who eventually bags it will always feel special.
