Last week, the most technologically advanced Pagani ever, the Huayra BC. This week, we get to hear and see the Huayra BC in action for the very first time. Well, this is the first time we've seen it in action without camouflage on. In a video, which looks to be created by SpeedHunters, the Huayra BC starts up and accelerated down a road on Mount Etna, letting us hear its twin-turbo V12 engine that was exclusively developed for Pagani by Mercedes-AMG. Behind that sound is over 750 hp and 737 lb-ft of torque. Could this be the best sounding Huayra out there? Let us know your thoughts on the BC in the comments below.
