What Are the GSR II Regulations? What Changes Are Being Made in Which Vehicles?

As of July 7, 2024, the publication date of this article, the new regulations have become mandatory. We explore what GSR II Regulations are and which systems are becoming mandatory in which vehicles.

What Are the GSR II Regulations?

Known as the second level of general safety regulations, GSR II encompasses a set of systems that must be mandatorily applied to vehicles. These regulations, defined by EU 2019/2144 in 2019, set mandatory standards for new vehicle production.

What Systems Are Changing in Vehicles with GSR II?

As of July 7, 2024, the GSR II regulations impact the following vehicle categories: M1 category cars, M2 and M3 category buses, N1 category vans, N2 and N3 category trucks, and O3 and O4 category trailers. There are no regulations affecting O1 and O2 category vehicles as of this date.

  1. Frontal Full-Width Impact – ECE R137
    • Mandatory for M1 category vehicles and N1 category vans with a maximum loaded weight not exceeding 3500 kg.
  2. Pole Side Impact – ECE R135
    • Mandatory for M1 category vehicles and certain N1 category vehicles with a maximum loaded weight not exceeding 3500 kg. Optional for other N and M category vehicle manufacturers.
  3. Rear Impact – ECE R153
    • Applicable to M1 and N1 category vehicles. Previous approvals under ECE R34 Series 3 will be considered equivalent.

  7. Emergency Lane Keeping System – (EU) 2021/646
    • Applies to M1 and N1 category vehicles. Vehicles with hydraulic power-assisted steering systems have until July 7, 2026, to comply. However, these vehicles must have a lane departure warning system (ECE R130).
  8. Advanced Emergency Braking on Light-Duty Vehicles – ECE R152
    • Applicable to M1 and N1 category vehicles, with a compliance deadline for pedestrian collision requirements extended to July 7, 2026.

    • The system became mandatory for M1 category vehicles on July 6, 2022, and will be required for N1, N2, M2, M3, O3, and O4 category vehicles starting July 7, 2024.
  10. Protection of Vehicles Against Cyberattacks – ECE R155
    • Mandatory during type approval processes for M1, M2, M3, N1, N2, and N3 category vehicles.
  11. Intelligent Speed Assistance – (EU) 2021/1958

  19. Platooning
    • If equipped, N2, N3, M2, and M3 category vehicles must obtain mandatory approval from July 7, 2024. However, the regulation has not yet been published, so approval is not required.
  20. Systems to Provide Safety Information to Other Road Users
    • Applicable to autonomous M1, M2, M3, N1, N2, and N3 category vehicles. The regulation has not yet been published, so approval is not required.

What Should Manufacturers Do?

Complete vehicle manufacturers must have obtained approvals for the mandatory systems according to vehicle categories and ensure that vehicles produced (with a Certificate of Conformity date) after July 7 are equipped with these systems. Body-builders must obtain necessary approvals for mandatory systems not present in the base vehicle. For example, if the base vehicle is in a different category and the system is not mandatory for that category, the body-builder must obtain approval for the necessary systems. Additionally, regardless of the base vehicle, they must complete processes related to ECE R155 cybersecurity management systems.

What Will Happen to Existing Vehicles During the GSR II Transition?

Depending on the country, vehicles in stock that do not meet GSR II requirements may be sold for a limited time with end-of-series approval. Vehicles that do not receive approval within the limits cannot be registered. For example, a vehicle without end-of-series approval cannot be registered as of July 7. This situation has caused a crisis for car dealerships in many countries.

I have been acquainted with homologation in the automotive sector for over 10 years now. We have accomplished great things in many projects within various teams. Adapting to the recently updated homologation processes has been particularly exciting. Integrating past experiences with new procedures fosters a fertile ground for innovation and productivity. Having a special interest and expertise in both automotive and technology,

I am thrilled by the prospect of these fields converging in the future. It is a privilege to be a part of the journey in automotive and technology!

For this reason, I have decided to launch a blog project that I have long envisioned, where I can share my experiences and assess developments in the industry.

Previously, in the early years of my career, I managed a well-loved project named Homologasyon.xyz, which offered content in Turkish. I had decided to discontinue this project for various reasons.

Now, I am excited to engage with an international audience through a new blog project, sharing knowledge and insights. I hope my efforts will contribute positively to the industry.

Please feel free to contact me with your views and suggestions.
