The 40-second video shows a group of engineers with various testing equipment at a racetrack (our guess would be the Nürburgring). A prototype is then seen on the track while engineers keep a close eye on the vehicle's sound, which includes snaps, crackles, pops, and other noises you would expect in a sports car.
We know that the first N vehicle, the i30 N will feature a new 2.0L turbo-four and a manual transmission (most likely a six-speed). The i30 N will launch in 2017.
