The N’Fera AU7 was specially designed with the aim of reducing running noise in the car interior. Two approaches to this were pursued: on the one hand, noise-absorbing material has been used, successfully reducing noise level by 15 per cent; on the other hand, the profile structure was adjusted. Five adjacent profile blocks ensure smoother running and enhanced distribution of frequencies, resulting in a more pleasant running sound.
