Lamborghini has just revealed its latest convertible in Geneva. The Aventador SVJ Roadster takes the ultrafast SVJ coupe and drops the top.
Making its first debut on a Lambo way back in 1971 on the Miura, the J in SVJ stands for jota, which is Spanish for the letter "j." Here, it refers to the FIA Appendix J racing rules, The SV is for Super Veloce which means fast.
The SVJ starts with a version of Lambo's naturally aspirated V12 that puts out 770 hp and 509 lb-ft of torque. That's 19 more ponies than the SV for those keep track at home.
It uses Lamborghini's ALA active aerodynamics system, along with the Lamborghini Dinamica Veicolo Attiva 2.0 computer. Aero flaps can be adjusted in 500 milliseconds to tweak handling and grip in real-time. The computer can adjust the balance left or right as well as providing more and less downforce, which the company says makes it quicker around corners.

The automaker says that stiffness is not compromised, even with the roof removed. The magnetic suspension has been tuned for "maximum body and wheel control." Anti-roll bar stiffness is up 50 percent compared to the SV roadster.
But the real trick here is the downright practical - for a hypercar - removable roof. It's made from carbon fibre, and Lamborghini says once you pop the quick-release levers to remove it you can store the panel under the front hood. The roof weighs less than 6 kg, and the roadster conversion adds just 50 kg to the coupe putting it at 1,575 kg.
It will hit 100 km/h from a standstill in 2.9 seconds and has a top speed of more than 350 km/h. Tromping on the big carbon fibre rotor brakes will bring it to a stop from 100 km/h in a mere 31 metres.
Lamborghini is making just 800 SVJ Roadsters, arriving at dealers later this year.
