I know I've seen it, but its well worth hearing that sound again.
Anyone here ever physically operate a car on a dyno? I'm wondering what its like. I'm a little curious about the speeding down portion of the process actually. I'm not sure if this video is real, but I am surprised to see the downshifting happening at the end. I would think you would just coast to a stop rather than apply reverse forces on the system. Of course this video is for dramatic effect and not simple measurement so it's not that surprising.
I'm just wondering about the characteristics of the dyno machine itself, if that makes any sense...
super impressive. I can honestly say two things: 1, I'd never thought "I want an R8" until I saw(heard) this. And 2, I confess to watching it twice before switching to the good noise cancelling headphones and watching it like 3 more times. That turns into the shortest minute ever.

Sure Kreso, after the catalisers and mufflers are added back its not going to be as raw, but its the principle, you have to applaud that ad 
The industry is killing the sportars with their green political correcteness when sportcars do nothing for the atmosphere compared to polluting cars in the third world, not to mention the industry there, its pure hipocracy. So ridiculous that it has even reached Formula One, making what were supposed to be the fastest and sportiest race cars in the planet sound like pathetic 30 year old trucks.

So you will not be a customer for the 2016 Hybrid 4cyl Turbo PDK 991 that can also park and steer itself? Maybe it will even perfume itself like a new Mercedes! 
In a lot of ways new sportscars are killing themselves off. Too big, not agile and chock full of technology they are just becoming hi speed zombie machines.

To the car, the dyno feels just like any other road. So during coasting down, especially in Sports mode or something, the ECU automatically downshifts to match road speed with gearing/engine speed. All dual clutch gearboxes do that, in my Turbo S, 12C and the Speciale.
There are a surprisingly high amount of tech involved even in last generation's sports car, almost like current gen. The computer doesn't do what humans do on coasting down, i.e. disengage the clutch and let the car coast/brake down by itself until stop. It keeps the transmission in control in case power is needed all of a sudden.
