This is the Lamborghini Aventador SuperVeloce, an upcoming more hardcore version of the Lamborghini Aventador. The 'SV' title is only applied to hardcore Lamborghinis, so you can probably expect this to be lighter and more powerful - perhaps the 720 PS tune from the limited edition LP 720-4 or even more?

This appears to be a production car undergoing a professional photo shoot of sorts, as one of the photos sent by our spy photographers show an SUV with a photography rig tailing it. There's also a sticker with the letter 'SV' on the car if there was ever any doubt this was an SV car.

The changes we can observe are a different front bumper, rear diffuser and a big wing. The exhaust output is now four tail pipes instead of just one on the regular Aventador. The tail pipes don't really look finished so we guess this can't be a photoshoot for the official unveiling?
