V12 in a tunnel, 'nuff said.
Lamborghini hasn't exactly put out a lot of cars which don't sound incredible, but it never hurts to be reminded of this from time to time. The Murcielago LP670 SuperVeloce you'll see in this video has a bit of extra help from a Reiter exhaust. The rear wing is also from Reiter, which is all fine and good, although it doesn't make the car sound any better. And it does sound glorious, with the driver hitting the downshifts for the tunnels and underpasses.
If you're wondering where this, but don't recognize the scenery and can't make out the license plates as they fly by, it's in the Netherlands.
