NATRAX Testing & Homologation in India — Proving Ground & CMVR Type Approval

Home › Services › NATRAX Testing

What is NATRAX in India?

National Automotive Test Tracks (NATRAX) is a state-of-the-art automotive testing and certification centre developed under the National Automotive Testing and R&D Infrastructure Project (NATRiP), a flagship programme of the Ministry of Heavy Industries, Government of India. It occupies approximately 3,000 acres at Pithampur in Dhar district, Madhya Pradesh, roughly 50 km from Indore on the NH-52 bypass.

NATRAX was included as a notified test agency under Rule 126 of the Central Motor Vehicles Rules by MoRTH gazette notification G.S.R. 511(E) in 2019. Its dedicated high-speed, dynamic platform, braking, noise and gradient tracks are used for vehicle type approval testing alongside development and validation work.

The centre's defining asset is an 11.3 km high-speed track — the longest in Asia and among the largest proving grounds in the world — capable of supporting maximum-speed runs of up to 375 km/h. In total NATRAX operates 14 test tracks and 5 laboratories, and holds NABL accreditation under certificate no. TC-10609 with effect from 14 May 2022.

⚖️ Statutory basis: Rule 126 of the Central Motor Vehicles Rules, 1989 (framed under Section 110 of the Motor Vehicles Act, 1988) requires that a prototype of every motor vehicle manufactured in or imported into India be submitted to a notified test agency for testing. Rule 126A governs Conformity of Production (COP). A vehicle without a valid Type Approval Certificate cannot be issued Form 22 and cannot be registered with an RTO; imported consignments are liable to be held at customs.

How to Book & Complete NATRAX Testing

PCN Global India manages the full NATRAX engagement — test plan definition, booking through the proving ground management system, vehicle logistics to Pithampur, instrumentation coordination, test witnessing and report closure.

Test Requirement Definition

Identification of exactly which regulatory tests and which tracks or laboratories are required, mapped to the applicable CMVR rules and AIS standards.

Registration & Slot Booking

Customer registration on the NATRAX proving ground management system, test plan submission, slot reservation and fee payment.

Technical Documentation Submission

Preparation of vehicle technical data, test-condition declarations, instrumentation plans and safety documentation.

Vehicle Logistics & Preparation

Transport of prototypes to Pithampur, running-in, tyre and load condition setup, and pre-test inspection.

Instrumentation & Dry Runs

Fitment of measurement instrumentation, calibration checks and dry runs to validate the setup before certification runs.

Certification & Development Runs

Execution of regulatory and development test runs across high-speed, braking, noise, gradient and dynamics tracks with our engineer present.

Report Review & Issuance

Review of raw data and draft reports, resolution of anomalies, re-run planning and issuance of the final NATRAX test report.

Onward Certification Support

Use of NATRAX reports within the wider homologation file and coordination with the certifying agency through to Type Approval and COP.

⏱ Typical Timeline

Planning & Slot Booking2–4 weeks
Track & Lab Testing1–8 weeks
Report Issuance2–4 weeks
Total End-to-End5–16 weeks

Timelines assume complete documentation at submission and no major re-test. Delays are almost always caused by incomplete technical files or a failed test requiring design change.

Documents Required for NATRAX Testing

NATRAX requires vehicle technical data and test-condition declarations rather than a full certification dossier, though homologation programmes carry the standard CMVR documentation alongside. We provide a customised checklist for your test plan.

Frequently Asked Questions (FAQs)

Common questions about NATRAX testing, the high-speed track, homologation and proving ground services.

What is NATRAX?

NATRAX (National Automotive Test Tracks) is a government automotive testing and certification centre at Pithampur near Indore, Madhya Pradesh, developed under the NATRiP programme of the Ministry of Heavy Industries. It spans approximately 3,000 acres and operates 14 test tracks and 5 laboratories.

Is NATRAX a notified CMVR test agency?

Yes. NATRAX was included as a test agency under Rule 126 of the CMVR by MoRTH gazette notification G.S.R. 511(E) in 2019. Its tracks are used for type approval testing within its notified scope, alongside development and validation work.

How long is the NATRAX high-speed track?

The high-speed track is 11.3 km long, making it the longest in Asia and among the largest proving grounds in the world. It supports maximum-speed testing at speeds of up to 375 km/h.

What tests can be done at NATRAX?

Maximum speed, high-speed durability, constant-speed fuel consumption, brake and ABS performance across multiple friction surfaces, pass-by noise, gradeability and hill start, vehicle dynamics and ESC evaluation, ride comfort, fatigue durability, off-road performance, wet grip, and battery and powertrain laboratory testing.

Is NATRAX NABL accredited?

Yes. NATRAX holds NABL accreditation under certificate number TC-10609, effective from 14 May 2022.

How is NATRAX different from ARAI, ICAT and GARC?

NATRAX is primarily a proving ground — its strength is track-based performance, dynamics and durability testing at a scale no other Indian facility matches. ARAI, ICAT and GARC offer broader end-to-end certification laboratory coverage including crash, emission and component testing. Many programmes use NATRAX for track work and another agency for the balance of the homologation file.

Where exactly is NATRAX located?

NATRAX is on the Agra–Mumbai Highway (NH-52) next to the Pithampur flyover, Post Khandwa, near Pithampur, Dhar district, Madhya Pradesh 454774 — about 50 km from Indore and centrally placed relative to most Indian OEM plants.

Can NATRAX test electric vehicles?

Yes. NATRAX runs battery test systems, a powertrain laboratory and vehicle instrumentation facilities, and its tracks are used to validate EV range, thermal behaviour, high-speed performance and dynamics under real driving conditions.

What is NATRAX's role in the PLI-Auto scheme?

NATRAX provides testing services to evaluate Advanced Automotive Technology vehicles and components under the Production Linked Incentive scheme for Automobiles and Auto Components, which manufacturers need in order to claim incentives.

How far ahead do I need to book a slot?

Realistically 4–8 weeks for high-speed track work, and longer during peak seasons. Programmes needing multiple tracks or specific ambient conditions need more planning. We handle booking, sequencing and logistics so the vehicle and the slot arrive together.

Ready to Plan Your NATRAX Test Programme?

A wasted track slot costs weeks and a prototype. Our consultants define the test plan, book the right tracks in the right order, manage vehicle logistics and instrumentation to Pithampur, witness the runs and close the report — then carry the results through to Type Approval.
