We have barely gotten used to Lamborghini’s Aventador supercar, and the now the company has released its most radical car, the Aventador J.
It is not a prototype, it is not a concept car, but a one-off model manufactured to show Lamborghini’s expertise in using carbon-fibre technology, among other things.
Lamborghini used the Aventador LP700-4 as a starting point for the J. Since both the roof and front windshield have been removed, the engineers have changed the carbon-fibre monocoque significantly, for instance the two new safety bars behind the seats. This Aventador J is said to be lighter than the LP700-4, since the air-conditioning, audio and navigation systems have been removed. This means that all the buttons – and the screen – associated with these systems have been binned, too. The result is a minimalistic interior that is focused around the driver to make the driving experience as visceral as possible.
Although the doors still open in the traditional upward way, the tiny side window strips are fixed, again contributing to a lower weight. To assist with downforce, especially since the windscreen and roof are gone, the J features different front and rear bumpers. These bumpers have what Lamborghini calls carbon-fibre fins, which deviate air in such a way that downforce is increased on both the front and rear parts of the car.
Also gone is the engine cover, replaced by a frame. The X-shape carbon-fibre geometry allows two openings for easy visibility of the two banks of cylinders. As with the LP700-4, the 6,5-litre V12 engine develops 515 kW while the sprint to 100 km/h should be done and dusted in less than 3,0 seconds.
Lamborghini claims that the J will be able to achieve a top speed of more than 300 km/h. No wonder the driver in the press pictures wore a full-face helmet.
Finally, the “J” refers to the FIA’s Appendix J that gives the technical specifications for the various racing classes.
Lamborghini confirmed that there wouldn’t be any other Aventador J models. This is a strictly one-off car as the original 1970 Jota. The latter was based on a Lamborghini Miura that featured improved performance and which was also redesigned in several ways.
For sale?
What’s more, the J will be sold, and it will be interesting to see if the future owner will store it in his private collection or will actually drive it. Nevertheless, this is just the start of the Aventador story.
