INTA-FFII Agreement 2026: What Changes in Vehicle Homologation

Key data

Vehicle manufacturers and homologators in Spain have had a new institutional collaboration framework at their disposal since July 20, 2026. The Resolution 420/38343/2026 publishes the renewed agreement between INTA and FFII, two organizations that have already been collaborating since 1985 and that now formally structure that relationship to respond to the growing regulatory complexity of the sector, driven by electric vehicles and advanced driving systems.

The renewal is not a mere administrative formality: it represents an explicit coordination of complementary technical capabilities that, in practice, expands manufacturers' options to complete their homologation processes in Spain with greater agility and under a recognized institutional umbrella.

What does this regulation establish?

The agreement defines a structured collaboration between two entities with complementary roles within the Spanish vehicle homologation system. Each party contributes distinct capabilities:

Both entities share the status of Homologation Technical Services, designated by the Ministry of Industry and accredited by ENAC (National Accreditation Entity). This guarantees that tests and certifications carried out under the agreement framework have full legal and regulatory validity.

The scope of collaboration covers the following types of procedures:

• Individual homologations
• Partial homologations
• Type homologations
• Vehicle modifications
• Market surveillance
• In-service conformity

A relevant aspect for companies working with both entities: each party operates its facilities under its own responsibility, without transfer of management or ownership. No joint entity is created nor are structures merged: it is a functional collaboration that maintains the operational independence of each organization.

Economic and operational impact

The agreement does not establish direct fees or prices for manufacturers, so there is no new regulatory cost resulting from its publication. The impact is mainly operational and strategic:

• Greater technical coverage in a single ecosystem: manufacturers can access driving tracks (INTA) and laboratories specialized in EMC, noise, photometry and ADAS (FFII) within a recognized collaboration framework, reducing the need to coordinate multiple independent providers.
• Response to the complexity of electric vehicles and ADAS: homologation of electric vehicles and advanced driving systems requires tests in areas such as electromagnetic compatibility and photometry, precisely the specialties provided by FFII. The agreement facilitates joint access to these capabilities.
• Legal certainty: as these are two Homologation Technical Services designated and accredited by ENAC, the results of the tests have full validity before the Ministry of Industry, eliminating uncertainties about the recognition of the tests performed.
• No change in responsibilities: each entity maintains its independent responsibility for its facilities, which means that contracts and commercial relationships with each one remain separate.

Who does it affect?

• Vehicle manufacturers that need type, individual or partial homologations in Spain, especially those developing electric vehicles or with ADAS systems.
• Homologation companies that manage certification processes for third-party manufacturers.
• Technical laboratories in the automotive sector that compete or collaborate with INTA or FFII in the market for testing and certification services.
• Companies that carry out vehicle modifications subject to homologation.
• Component manufacturers that must pass market surveillance or in-service conformity tests.

Practical example

An electric vehicle manufacturer that wants to obtain type homologation in Spain needs, among others, electromagnetic compatibility (EMC) tests —to verify that the electrical system does not interfere with other devices— and driving track tests to validate the dynamic behavior of the vehicle.

Before the renewed agreement, this manufacturer had to coordinate independently with FFII (for EMC laboratories) and with INTA (for the tracks). With the new collaboration framework, both entities act in a coordinated manner within the same homologation process, which reduces coordination times and offers a clearer point of contact. The manufacturer continues to contract with each entity separately —given that there is no transfer of management— but the joint work is now formally structured and recognized by the Ministry of Industry.

What should companies do now?

1. Review homologation processes underway: if you have active or planned homologation projects for 2026-2027, verify whether the required tests (EMC, noise, photometry, ADAS, tracks) fit with the joint capabilities of INTA and FFII.
2. Contact INTA and/or FFII to explore the new framework: given that the agreement has been in force since July 20, 2026, both entities can guide you on how to access their services in a coordinated manner.
3. Verify ENAC accreditation of the tests: ensure that the tests you contract are covered by the current accreditation of each entity, especially if the process includes type homologations before the Ministry of Industry.
4. Update homologation plans for electric vehicles and ADAS: if your roadmap includes these segments, incorporate FFII capabilities (EMC, photometry, ADAS) and INTA (tracks) as a reference in your technical planning.
5. Maintain separate contracts with each entity: remember that the agreement does not create a joint entity. Each commercial relationship remains independent with INTA and FFII.
