Lamborghini is bringing its “most reactive car" to the Geneva Motor Show this week, a car almost certain to be the hardcore Aventador SuperVeloce spied recently during a photo shoot in southern Europe.

Now we have our first look at what’s likely to be an open-top version of the car. This photo, sourced from the Teamspeed forums, shows a prototype for what’s likely to be an Aventador SuperVeloce Roadster.

Giving away the car’s identity are the aggressive rear diffuser, extra vents in the rear bumper, and the quad-pipe exhaust tips. While the rollover protection looks similar to that on the stock Aventador Roadster, the engine cover appears unique, signaling some differences here.

Lamborghini only applies the SuperVeloce title (SV for short) on its most extreme models, and this Aventador SV Roadster already appears much more extreme than the stock Aventador Roadster. If previous SV models like those based on the Miura, Diablo and Murcielago are any indication of what to expect, look for less weight and more power.

Lamborghini’s 6.5-liter V-12 fitted to the Aventador LP 700-4 develops 691 horsepower, but more potent versions of the engine exist. In the Aventador LP 720-4 50° Anniversario power was dialed up to 710 hp, and in the Veneno the same engine produces as much as 740 hp. The Aventador SV could pack the most potent version of the engine we’ve seen yet.

Stay tuned for an update.
