His name is Nissan Acoustic Meta Material. Studies on this technology had already started as far back as 2008. The structure of this material is very interesting.
Nissan has made this insulation material combining a reticular structure with a plastic film. In this way it was possible to limit the transmission of sounds with frequencies of 500-1200 hertz, such as road and engine noise.
In addition to allowing better soundproofing of the passenger compartment, this material offers a another very important advantage which is lightness. According to the manufacturer, the weight is even a quarter of that of the classic rubber insulating panels used today on cars.
Furthermore, thanks to its very simple structure, i production costs are identical if not lower than those of today’s panels.
An insulating material that can therefore be applied to cars, improving not only ride comfort but also fuel consumption by virtue of weight savings.
A very interesting technical solution especially for the electric cars where every gram saved translates into an increase in autonomy.
As already announced in late December, the Japanese company brought the American fair to the Nissan Ariya concept, a particular “self-driving” golf ball and an electric ice cream van.
The Japanese manufacturer has used the Nissan Ariya (car that was the basis for this editorial) to demonstrate the goodness of its new soundproofing material.
At CES 2020, Nissan also brought the All-Wheel Control technology called e-4ORCE which allows you to offer a independent control on each wheel on electric cars with dual engine and all-wheel drive, already previewed at the Tokyo Motor Show.
This technology provides instant torque to all four wheels to offer power and handling in a balanced way on a par with many premium sports cars.
The end result is a high ride comfort thanks to a new energy recovery system that limits pitching and an increase in safety in all driving conditions.
E-4ORCE technology is always present within the Nissan Ariya concept.
