A few weeks ago we spotted what's clearly a hardcore version of the Pagani Huayra. It's about damn time. We've reached out to our sources at Pagani for some indication as to its specs, name, etc. We'll let you know once an answer arrives. But until then, that very same hardcore Huayra has been caught once again testing, only this time it's getting its tires dirty at the track. It's impossible to miss that large carbon fiber rear wing and rear diffuser. Best of all? It sounds absolutely sick.

We're guessing that can be the work of a modified twin-turbo V12 and a different exhaust system. Rumor has it this Huayra will deliver more than 800 hp. We also know a Huayra roadster is on the way very soon, and it could be entirely possible both that and the hardcore coupe version will arrive this March at Geneva. Enjoy the music for now.
