Audi in the wind tunnel


The primary task of the Wind Tunnel Centre is the development of Audi’s production vehicles. The range stretches from compact premium models, dynamic SUVs and luxury sedans all the way through to high-performance sports cars.

In line with Audi’s guiding principle “Vorsprung durch Technik”, the wind tunnel tests not only optimise economy and noise levels but also ensure a functional form. Two current examples: the dynamic design and exclusive standard of comfort offered by the Audi A8 were developed and tested using the Wind Tunnel Centre. With the aim in mind of bringing the DTM feeling to the street, the Audi A4 DTM was also a frequent visitor to the aeroacoustic wind tunnel.

 

A tradition of aerodynamic research

By its focus on aerodynamics, Audi is simply carrying on a tradition: the Audi 100 produced in 1982, with a drag coefficient of 0.29, was considered for many years as the yardstick and entered the company’s history books with its world-beating drag coefficient. This breakthrough meant that aerodynamics had finally found its place in automobile technology. Since then, no passenger vehicle has been launched without the use of flow technology to determine its shape. Audi set another record with the Audi A2: the Audi A2 was the first production car with a drag coefficient of 0.25.

 

Aerodynamic tests in Audi motor sport

The shape of long-distance sports cars was also optimised at the Wind Tunnel Centre. As a result, the Audi works team gained a place on the podium at the first attempt in 1999 with the Audi R8R at the 24 Hours of Le Mans. In 2006, the first victory for a diesel-powered sports car in the legendary race wrote headlines worldwide. In 2009, Audi will be on the starting grid at Le Mans for the eleventh time, now with its new R15 TDI. The brand’s record to date: ten races, eight wins.
