What is ARAI?
ARAI (Automotive Research Association of India) is an autonomous body under the Ministry of Heavy Industries, Government of India, headquartered in Pune. Established in 1966, ARAI is India's premier automotive R&D and testing agency, responsible for:
- Type approval certification, mandatory testing before any new vehicle model can be sold in India
- Fuel efficiency certification, the mileage figures manufacturers publish in advertising
- Emissions testing, compliance with Bharat Stage (BS) norms (currently BS6 Phase 2)
- Safety testing, crash tests and component safety standards
Key Things to Know
- ARAI figures are for comparison, not prediction. Use them to compare two models, not to predict your monthly fuel bill.
- Measure your own mileage using the full-tank method and the Bike Average Calculator.
- BS6 Phase 2 (OBD2) from 2023 requires real driving emissions (RDE) monitoring, a step toward bridging the lab-to-road gap.

Frequently Asked Questions
Why is ARAI mileage always higher than what I actually get?
ARAI mileage is measured under controlled laboratory conditions: constant speed on a chassis dynamometer, no traffic, ideal 25°C temperature, new engine with fresh oil, and optimal tyre pressure. Real-world riding introduces traffic stops, varying speeds, engine warm-up periods, and load, all of which reduce efficiency. A 10–20% gap from ARAI figures is completely normal. Measure your own mileage using the [Bike Average Calculator](/in/bike-average-calculator/) for accurate budgeting.
Is ARAI certification mandatory for all vehicles sold in India?
Yes. All motor vehicles sold in India, two-wheelers, cars, commercial vehicles, must obtain ARAI type approval (or equivalent from ICAT, another authorised testing agency) before they can be sold. This includes safety testing, emissions compliance (BS6 norms currently), and fuel efficiency certification. Manufacturers cannot legally sell a vehicle without this certification.
What is the difference between ARAI and ICAT?
ARAI (Automotive Research Association of India, Pune) and ICAT (International Centre for Automotive Technology, Manesar) are both government-authorised vehicle testing agencies. Both can issue type approval certificates. ARAI is older and more established, associated primarily with SIAM (Society of Indian Automobile Manufacturers) members. Many manufacturers use either agency, both produce valid certifications that must be displayed in advertising.
