- Mercedes-Benz India becomes the first automaker in India to receive AIS 175 wind tunnel facility certification.
- The approval enables indoor road load determination using wind tunnel and dynamometer testing methods.
Mercedes Benz India Private Limited has received official certification from the Automotive Research Association of India (ARAI) for its wind tunnel testing facility, allowing the company to determine road load data for M1 category passenger vehicles. The approval authorizes the manufacturer to use a combination of an aerodynamic wind tunnel and a flat belt dynamometer to establish baseline road resistance forces. This certification marks an important development in the adoption of advanced vehicle testing technologies within the automotive sector and supports compliance with evolving regulatory requirements.
ARAI Approves Advanced Road Load Testing Facility
The certification recognizes the facility's capability to perform specialized testing in accordance with the AIS 175 regulatory standard. Through the integration of aerodynamic wind tunnel systems and dynamometer equipment, the facility can generate road load data in a controlled laboratory environment. The methodology is intended to achieve a strong correlation between indoor simulation results and measurements traditionally obtained through physical testing on dedicated tracks, helping manufacturers improve testing efficiency while maintaining technical accuracy.
AIS 175 Standard and Regulatory Requirements
The AIS 175 standard forms part of the Worldwide Harmonized Light Vehicles Test Procedure used for automotive exhaust emission measurement. The framework was mandated by the Ministry of Road Transport and Highways through a government notification issued on February 4, 2026. Under the implementation roadmap, the testing procedure will become mandatory across the automotive industry in India from April 1, 2027. The regulation establishes uniform testing requirements and provides manufacturers with approved methodologies for determining vehicle performance parameters.
Indoor Testing Alternative Under Harmonized Procedure
The harmonized regulatory framework permits vehicle manufacturers to determine road load values using an indoor testing approach instead of conventional outdoor coast down testing. By utilizing integrated wind tunnel and dynamometer facilities, automakers can establish vehicle road resistance characteristics within a controlled environment. This option offers greater consistency in testing conditions while supporting compliance with regulatory standards associated with emissions and vehicle certification activities.
