Volkswagen Opens Wind Tunnel Efficiency Centre

Volkswagen brand opened a new Wind Tunnel Efficiency Centre in Wolfsburg, which it says is 'one of the most modern and efficient in the industry'. Here, vehicles can be tested at wind speeds of up to 250 kmph, simulating real traffic conditions with a view to reducing drag, fuel consumption and emissions. In addition, driving simulations under all the climatic and environmental conditions normally experienced throughout the world can be conducted - at temperatures between -30 and +60 degree Celsius.

Dr. Herbert Diess, CEO of the Volkswagen brand said, "By 2020, we will renew our entire product portfolio as well as expanding it in key segments. All in all, our development teams are working on more than 50 vehicle projects."

As regards aerodynamic testing, Board Member for Technical Development Dr. Frank Welsch emphasizes: "These tests are a key factor in improving efficiency and reducing emissions. Thanks to the new center, we are also outstandingly well positioned for the future with respect to other development areas such as aeroacoustics and electric vehicle range."

The flat belt balance ensures that real-world driving operation can be simulated

In the aerodynamics and acoustics wind tunnel, especially the flat belt balance ensures that real-world driving operation can be simulated. Each individual wheel of the vehicle is positioned on its own flat belt. This allows turning motions of the wheels in a way, which is similar to driving on the road. The balance, with integrated camera system, aligns each model tested fully automatically in less than five minutes. The previous system required about 30 minutes. And the acoustic insulation of the tunnel makes it one of the quietest automotive wind tunnels in the world. At a wind speed of 160 km/h, the tunnel only reaches a sound pressure level of 65 decibels, comparable with TV operated at a reasonable volume or normal speech.

With the new centre, the Volkswagen brand will significantly reduce the cost of tests previously carried out in remote areas. In addition, cooperation between development areas such as vehicle safety, design, acoustics and comfort will be facilitated as a result of the shorter distances involved.
