- Maruti Suzuki Wind Tunnel Facility Approval enables certified vehicle testing.
- Advanced validation method accelerates future emission testing processes.
India-based Maruti Suzuki India Limited has received official approval from the Automotive Research Association of India (ARAI) for its wind tunnel facility to carry out vehicle road-load determination for M1-category passenger vehicles in accordance with the AIS-175 standard. The approval, announced on July 16, allows the company to perform certified road-load determination by using its wind tunnel together with its chassis dynamometer facility, provided the measured results demonstrate good correlation with vehicle test track data.
ARAI Approves Wind Tunnel-Based Road-Load Determination
The certification enables Maruti Suzuki to use a combination of wind tunnel and chassis dynamometer testing for determining vehicle road load under the AIS-175 framework. The approval is applicable to M1-category vehicles and requires that laboratory-generated results closely match those obtained through conventional track testing. This approach provides manufacturers with an additional validated testing methodology while maintaining compliance with established technical requirements.
Scope of the AIS-175 Certification
AIS-175 is the automotive standard governing Worldwide Harmonised Light Vehicles Test Procedure (WLTP)-based vehicle exhaust emission testing. According to ARAI, the approved wind-tunnel-based road-load determination method establishes a new benchmark for faster and more advanced vehicle testing and validation. The certification supports more efficient testing activities without changing the technical requirements or validation standards defined under the regulation.
