In his first drive review for Autoblog, contributing writer Jason Harper described the sound of the Lamborghini Aventador SVJ as a "GT3 race car married to a Learjet crossed with a Valkyrie warrior screaming at her husband. At full flog it's loud enough to make you wince and eradicate all conversation. It is the sound of a non-turbo V12 doing exactly what it's made for."

Now, imagine hearing all that without a pesky roof in the way. That's what you'll get with the Lamborghini Aventador SVJ Roadster unveiled at the Geneva Motor Show. It is the convertible version of the SVJ, which replaces the coupe's fixed roof with a carbon fiber panel that must be physically removed and stored under the hood. There is a not-insignificant weight penalty of 110 pounds for going topless, which certainly stands in contrast to the SVJ's various weight-saving measures.

Otherwise, the Roadster is business as usual for the SVJ. As a refresher, this Aventador would be the latest-and-greatest version with a track focus. Besides weighing less than the 730-horsepower Aventador S Roadster, it boasts 759 horsepower and 531 pound-feet of torque from its naturally aspirated V12. Lamborghini says the SVJ Roadster will accelerate from 0 to 60 mph in 2.9 seconds, which is 0.1 second slower than the coupe. It has a seven-speed automated manual transmission and all-wheel drive.

The SVJ features the second-generation Aerodynamica Lamborghini Attiva system (ATA), which basically adds an abundance of active aero elements designed to reduce drag and dramatically increase downforce. Those elements manage to selectively channel air away from the prominent rear wing to reduce drag (and therefore increase speed) on a straightaway, while allowing the wing to do its job and increase downforce when braking. It also effectively "stalls" air away from one half of the wing during cornering to provide extra downforce on the inside wheels during cornering and therefore increase grip.
For the roadster, airflow is uninterrupted regardless of whether the roof is in place or removed, and Lamborghini says the SVJ sees a 40 percent improvement in downforce compared to the old SV Roadster.

Other SVJ elements include a special rear-wheel steering system, while the Haldex fourth-generation all-wheel-drive system and magnetically controlled adaptive suspension have been specially tuned. For the latter, anti-roll stiffness has been improved by 50 percent compared to the SV Roadster.

Pricing for the SVJ Roadster starts at $574,966, not including the gas guzzler tax. Production will be limited to 800 units, and deliveries are set to begin this summer. Among the car's many "Ad Personam" customization options are 350 exterior colors, including the new bronzo zenas matte paint introduced along with the SVJ Roadster at Geneva.
