Earlier this month, Lamborghini unveiled the Aventador J speedster during the opening of this year’s Geneva auto show. As predicted, the Aventador J is just a concept at the moment. It is fully functional and it is a one-off vehicle.
The Aventador J is powered by a 6.5-liter V12 engine, which develops 515 kW / 700 hp and 690 Nm of torque. This is the same engine as the one used in the regular Aventador. Interestingly enough, even though it has not roof or windshield, the Aventador J has the same weight (1575 kg) as the regular model. This means that it should offer the same performance (0-62 mph in 2.9 seconds, 350 km/h top speed).
In case you’re wondering where is the “J” coming from, we’ll have to tell you that it’s from “Appendix J” of FIA’s rules, which define the technical specifications of various racecars. The Lamborghini Aventador J measures 4890 mm in length, 2030 mm in width and just 1110 mm in height. It features two small wind deflectors instead of a windshield, and a special periscope-like rear view mirror. One of the distinctive features of the Aventador J is its front air scoop with winglets, which give it a Formula 1 racing car profile. The rear of the Aventador J is dominated by a huge diffuser, four tailpipes and a large wing. The supercar comes with 20- and 21-inch wheels, special bumpers, which create downforce on each axle.
The Lamborghini Aventador J features a new carbon monocoque chassis, with two safety bars behind the seats. It features the same ISR transmission, permanent all-wheel drive and push-rod suspension as the regular Aventador, but it has no air conditioning or navigation system. The Aventador J also features a special set of seats, made from Forged COMPOSITE with flexible carbon fiber inserts. The Aventador J also features a new type of material, called Carbonskin, which is basically a flexible, soft type of carbon fiber.
Don’t expect to get navigation or air conditioning in the Aventador J. The only thing Lambo equipped it with are two programmable TFDT screen behind the steering wheel.
Lamborghini did not put a price on the Aventador J, which probably means it’s not for sale.
