The new Aventador SVJ Roadster two-seater will be produced in a limited run of 800 units, and Lamborghini boss Stefano Domenicali said it would be “as fundamentally exciting to drive as the Aventador SVJ but with an added exclusivity: the option of the open air”.
The car is being shown at Geneva alongside the new Huracán Evo Spyder.
It is fitted with a removable carbonfibre roof that is detached by quick-release levers in the cabin, and can be stored in a special compartment under the front hood. The mechanism weighs 50kg, meaning the machine weighs 1575kg, compared with 1525kg for the coupé.
The V12 engine, the most powerful series production unit in Lamborghini history, has an unchanged output of 759bhp at a maximum of 8500rpm, and 531lb ft of torque at 6750rpm, driving all four wheels. The 0-62mph time of 2.9sec is 0.1sec slower than that quoted for the coupé, but both have the same claimed top speed of 217mph. Lamborghini says the car’s performance and stiffness are unaffected by whether the roof is fitted or not.
As with the coupé, the Aventador SVJ Roadster features the latest version of Lamborghini’s ALA active aerodynamics system, which uses automatically operated motors to alter aero flaps on the carbonfibre rear wing to vary aero loads to achieve high downforce or low drag.
The machine also has the same side air intakes and fins as the coupé, which both aid cooling and reduce drag. The firm claims the machine offers 40% more downforce than the Aventador SV Roadster.
