Just the Facts:
  • Lamborghini describes the Aventador J as "the most uncompromising open super sports car" in its history.
  • Based on the production Aventador LP700-4, the Aventador J is a one-off reinterpretation of Lamborghini's two-passenger coupe, sans roof and windshield.
  • Lamborghini says it plans to build and sell just the one example — "no prototypes and no others for the Lamborghini Museum."

GENEVA — Lamborghini has unveiled the exotic Aventador J, which it describes as "the most uncompromising open super sports car" in its history."

Based on the production Aventador LP700-4, the Aventador J is a one-off reinterpretation of Lamborghini's two-passenger coupe, sans roof and windshield. With generous applications of carbon fiber and some unusual styling elements, the Aventador J is "the most extreme expression of Lamborghini DNA in existence," the company says.

To reinforce that notion, Lamborghini adds that it plans to build and sell just the one example — "no prototypes and no others for the Lamborghini Museum."

According to Lamborghini, the letter J is derived from FIA's Appendix J, which defines the technical specification of racecars in various classes. It is also a subtle reference to the 1970 Lamborghini Jota, a one-off version of the classic Miura that reportedly was built to conform to the Appendix J regs.

The two-passenger Aventador J shares the coupe's 691-horsepower 6.5-liter V12 and permanent all-wheel drive. The showcar's interior and exterior designs, however, mark a radical departure from the production model.

For starters, the chrome-red Aventador J stands only 43.7 inches tall, an inch and a half lower than the coupe.

Lamborghini eliminated the roof, replaced the windshield with a pair of small wind deflectors, installed tiny fixed side windows in the scissors-style doors, fitted an oversize carbon-fiber air scoop with "winglets" in front, then added a carbon-fiber rear diffuser and a massive rear wing. In addition, the redesigned front and rear bumpers incorporate carbon-fiber fins that act as "flow deviators" to increase downforce at both ends.

The Aventador J rides on custom five-spoke alloy wheels — 20-inch diameter in front, 21s in the rear — with carbon-fiber inserts that function like small fans to enhance brake ventilation.

The minimalist cockpit sports rollover bars behind the seats, a periscope-like rearview mirror, a small control panel housing the starter button and the switches for lights and transmission, plus a pair of programmable TFT displays behind the steering wheel.

Lamborghini put its expertise in carbon fiber to good use here, designing composite seats with inserts made of a new flexible carbon-fiber fabric it calls Carbonskin — woven carbon fibers soaked with a special epoxy resin to stabilize the material and keep it soft. Lamborghini has clad much of the cabin in the same matte-black material.

To accent the whole package, the designers added a red stripe that runs down the center of the car, including between the wind deflectors and through the cockpit.

Edmunds.com says: In Spanish, the letter J is pronounced jota (with a soft H).
