Geneva LIVE: Lamborghini Aventador SVJ Roadster

The roadster is only around 110 pounds  heavier than the hardtop SVJ.

Lamborghini's Aventador SVJ Roadster has made its global debut at the Geneva Motor Show, joining the hardtop SVJ that was revealed last year in Pebble Beach.

The roadster is only around 110 pounds heavier than the coupe, thanks to a carbon-fiber roof that is manually attached and stows inside the front hood.

With 770 horsepower and 531 horsepower, the SVJ's V12 is capable of bringing the open-top car to 62 mph in just 2.9 seconds and eventually reaching over 217mph. As an added bonus, upgraded brakes can bring the roadster to a halt from 62 mph in just 31 meters.

The SVJ Roadster carries over the hardtop's aggressive styling, next-generation vehicle dynamics control system and active aerodynamic elements. Airflow is said to be uninterrupted over an open roof, maintaining a 40-percent improvement in total downforce compared to the SV Roadster.

The SVJ Roadster is scheduled to arrive this summer with a starting price of nearly $574,000 and availability limited to just 800 units globally.
