Mercedes Benz on Monday said that has inaugurated two new climatic wind tunnels at its Sindelfingen site, designed to bring extreme weather conditions indoors.
These two new wind tunnels can bring temperatures from minus 40 to plus 60 degrees Celsius, hurricanes with wind speeds of up to 265 km/h, tropical rainfall and heavy snowstorms. If needs be, they can even provide a realistic simulation of a mercilessly hot sun.
One of these two tunnels is designed as a cold tunnel, with a temperature range of minus 40 to plus 40 degrees Celsius. The new hot tunnel, on the other hand, offers a temperature range of minus 10 to plus 60 degrees. Each tunnel is equipped with an integrated twin-axle roller dynamometer that allows speeds of up to 265 km/h – and thus with sufficient reserves for even sports cars to be tested on the rig here.
The new climatic wind tunnels replace the cold tunnel that has been used until now, in which temperatures down to minus 20 degrees Celsius and speeds of up to 64 km/h are possible, as well as a hot tunnel in which the maximum limits are plus 40 degrees Celsius and a top speed of 100 km/h.
A further advantage of the new climatic wind tunnels: they are designed to accommodate the use of hydrogen and therefore eminently suitable for all alternative drive systems of the future.
Special sensors and an effective air extraction system mean that fuel-cell powered vehicles can also be subjected to exacting test programmes here.
