Extreme temperatures are among the greatest stresses a vehicle can experience in real-world operation. That is why automakers and component suppliers are increasingly testing vehicles under conditions that simulate Arctic cold, tropical heat, and rapid temperature changes when moving between different climate zones. The goal is clear: to ensure vehicles operate reliably wherever they are used around the world. And this is exactly what AUREL Proving Ground makes possible thanks to its state-of-the-art climate chamber and its direct connection to real test tracks.<\/span><\/p>\n

Climate Chamber and ADAS Track in One Location<\/span><\/h2>\n

AUREL Proving Ground<\/span><\/a> offers a comprehensive testing environment for vehicle development and validation of both complete vehicles and individual components under extreme conditions. <\/span>The two-bay climate chamber<\/b> allows simulation of temperatures ranging <\/span>from +60 \u00b0C to \u221240 \u00b0C<\/b>. At the same time, it precisely controls <\/span>relative humidity from<\/b> 10% to 99% RH<\/b> \u2013 from extremely dry conditions to almost saturated air. This makes it ideal for accelerated durability testing, where several years of environmental exposure can be simulated in a short time, allowing engineers to verify the long-term resistance of tested components.<\/span><\/p>\n

\"\"<\/p>\n

One key advantage<\/b> of the Proving Ground is that the <\/span>climate chamber is located directly next to the <\/b>ADAS test track<\/b><\/a>. Vehicles can leave the chamber and immediately enter real test areas. This enables experts to seamlessly combine chamber testing with real operational loads and unpredictable scenarios, such as low-speed manoeuvres, intensive braking, repeated starts, or long-term endurance cycles. Results from laboratory measurements can thus be verified in practice immediately, without relocating to another facility.<\/span><\/p>\n

From Frost to Heat: Faithful Simulation of Extreme Conditions<\/span><\/h2>\n

The climate chamber provides precise and repeatable simulation of conditions vehicles encounter in the Sahara, the Norwegian mountains, or during sudden summer storms. Thanks to accurate <\/span>temperature and humidity<\/b> control, both complete vehicles and individual components can be tested.<\/span><\/p>\n

Imagine <\/span>temperatures<\/b> ranging from deep frost to tropical heat. Vehicles can be cooled down to <\/span>\u221240 \u00b0C<\/b>, corresponding to winter conditions in northern Scandinavia, Canada, or Siberia. At the opposite end of the spectrum, <\/span>+60 \u00b0C<\/b> can be applied \u2013 temperatures typical for summer operation in desert or subtropical regions, or for extremely overheated road surfaces. <\/span>Temperature has a major impact<\/b> not only on cabin comfort, but also on brake efficiency and brake lining performance, tire grip and deformation, chassis dynamics during heating and cooling, as well as the behaviour of lubricants and hydraulic fluids.<\/span><\/p>\n

At the same time<\/span>, the resistance of the bodywork and surface components<\/b> can be verified under long-term exposure to various weather and temperature conditions. <\/span>Humidity<\/b> is also closely monitored, with precise settings for testing condensation, corrosion, and electronic behaviour.<\/span><\/p>\n
