Overview
Driving confidently in any environment!
Our wind tunnel test facility pits cars against 200km winds created by ultra-large propellers measuring 8.4m. The KRW45 billion facility is the largest of its kind in Asia. Vehicles are put through a wide range of punishing tests that recreate diverse environmental conditions such as extreme temperatures, heavy rains and snow to ensure that they are able to deliver optimal levels of safety and durability under any circumstance, anywhere.
- Wind tunnel test facility
- The wind tunnel test evaluates the aerodynamics and aero acoustics of a vehicle. Tests are conducted to reduce wind resistance for improved fuel economy and reduced wind noise which is a major cause of noise when driving at high speeds.
- Key facilities include the main fan measuring 8.4m in diameter and capable of generating winds at speeds of up to 200km.
- In addition, an automotive electric scale can measure various forms of wind resistance encountered by vehicles during high speed driving.
- The sound-absorbing wall of the facility minimizes reflective noise and enables accurate measurements of noises created by the vehicle.
Environmental testing wing
- Cold chamber
- The temperature range of the cold chamber is -40℃-20℃ This is where various low temperature functional tests of various parts are conducted that assist in the development of systems to remove frost and humidity from windows to enable safe driving.
- The heater performance test helps to create a comfortable indoor environment even during the coldest winter days.
- Hot chamber
- Temperatures inside the hot chamber can be raised to 20-60℃. The facility is used to help develop the engine’s cooling and A/C systems. Additionally, electronic, rubber and plastic parts are put through the heat test.
- Heavy snow/rain chamber
- This facility is capable of generating 70mm of snow and 150mm of rain per hour,
- Thereby allowing researchers to assess the freezing of wiper systems and motor troubles due to frozen cooling fans. Various electric and electronic sensors and parts, as well as car interior and engine intake devices, are subjected to the test to locate any flaws resulting from exposure to snow or water.
- Road simulator
- The road simulator tests performance and safety when navigating rough roads as well as endurance for long-distance hauls.
- EMC test chamber
- The electromagnetic compatibility (EMC) chamber assesses the possibility of disturbances in electromagnetic waves, induction and audio reception while driving.
