How Euro NCAP tests a car, on paper: crash tests, dummies, vehicle selection and the 2026 protocol changes

Euro NCAP's five-star safety rating, in the organization's own words, helps consumers and businesses compare vehicles more easily and identify the safest car for their needs. Its explanation of its testing describes a framework in which vehicles are put through a wide range of safety tests and assessments, and where, for each star rating, a car must meet strict minimum safety requirements. Those requirements are updated every three years, so new cars are encouraged to include the latest safety features and technologies. According to Euro NCAP, around 90 percent of new cars sold have a valid Euro NCAP star rating.

This explainer walks through the framework as Euro NCAP itself describes it: who picks the cars, what the crash tests cover, how children and pedestrians enter the assessment, what the active-safety and post-crash evaluations add, and what changed for 2026.

Who picks the cars, and where they come from

Euro NCAP says it is not possible to test every car on the market. Each year, a selection of new and popular models is chosen; these are usually new releases, though sometimes cars already on sale are included. Each Euro NCAP member organization sponsors at least one vehicle test per year, typically selecting a model that is important in their market, and manufacturers often request their own models be rated - but Euro NCAP says the testing process is identical for all vehicles, regardless of who sponsors the test.

Crucially, the test car is meant to be the car a buyer can actually purchase. Euro NCAP says it works with manufacturers to identify the best-selling version of each car in Europe, and the test car is typically fitted with all the safety equipment offered as standard across the EU. Sometimes a second rating is given for cars fitted with an optional safety pack, to show how extra features can enhance safety. Vehicles can be obtained anonymously from dealerships, directly from manufacturing plants, or through random selection from production, and only type-approved, road-legal production cars are tested. Car makers have access to the protocols, but the way cars are selected is Euro NCAP's, and testing happens at independent laboratories.

Crash protection, children and people outside the car

The physical crash tests remain the core. Euro NCAP describes destructive laboratory crash tests designed to mirror everyday road accidents: frontal impacts designed to push a car's structure and restraint systems to their limits, side impacts simulating car-to-car impacts and cars skidding slideways into lampposts or trees, and crashes involving vulnerable road users. Sensors in advanced crash test dummies show how well adults and children would be protected. Computer simulations, rigorously validated against physical testing, are used to extend and broaden the evaluation of a car's true safety, although Euro NCAP says the emphasis will remain on physical tests.

Child occupant protection is assessed with its own dummies and a practical element. Euro NCAP uses advanced crash test dummies representing six- and ten-year-olds to assess protection in frontal and side collisions, and also verifies practical safety by examining how easily and securely a full range of child seats - from rear-facing infant carriers to forward-facing boosters - can be installed.

For people outside the car, the front-end design itself is examined. Euro NCAP evaluates a vehicle's front-end design to understand how it would physically interact with a pedestrian or cyclist during a collision, looking at the likely severity of injuries to critical body regions such as the head, pelvis and legs by analysing measured impact forces and decelerations. The body's position is that modern crash avoidance systems try to avoid or mitigate a collision, but it is imperative that cars have, by design, a high level of protection in case an accident should happen.

Active safety and what changed for 2026

Alongside crash protection, Euro NCAP tests the systems meant to prevent or lessen crashes. On a test track, it assesses the presence and effectiveness of crash avoidance technologies intended to avert or lessen critical crashes involving other vehicles, obstacles and vulnerable road users. Among the technologies evaluated are Autonomous Emergency Braking (AEB), Lane Support (LSS) and Automatic Emergency Steering (AES), as well as back-over and cyclist dooring prevention systems. Driver monitoring, speed assistance, adaptive cruise control and seat belt reminders are also part of the assessment of driving during normal conditions.

For driver monitoring specifically, Euro NCAP says that from 2026 its tests focus on improved system reliability and user acceptance, with points awarded for advanced systems that monitor driver behaviour in real time. Euro NCAP publishes the underlying protocols for manufacturers and automotive safety engineers: car safety protocols for 2026-2028 and for 2025, plus truck and van safety protocols, per its protocols section.

After the crash: rescue, eCall and the battery

A rating also covers what happens once the collision is over. Euro NCAP's post-crash assessment focuses on enabling rescuers to execute a rapid and safe rescue. Advanced eCall systems can get the emergency services to the scene of an accident as swiftly as possible, and those first on the scene can be put at risk if they are not aware of the location of high voltage batteries, fuel tanks, airbag inflators and seatbelt pre-tensioners. The manufacturer's rescue information for each vehicle is checked for completeness and compiled in the Euro Rescue app. Additional evaluations include post-crash door-opening performance, high-voltage battery safety, and vehicle behaviour in case of submergence.

Reading a rating today

• As read on Euro NCAP's latest-ratings page on 25 September 2026, the list included models rated under the 2026 protocol - for example GEELY E2, AION UT, CUPRA Raval and BMW iX3 - and 2025-protocol cars such as the Kia K4, Toyota C-HR and Hyundai NEXO, with some cars rated in both a Standard and a Safety Pack configuration.
• Assisted Driving gradings are published separately from the star ratings; the same 25 September 2026 reading showed recent 2025-protocol gradings from Moderate to Very good, including Tesla's Autopilot and Kia's Highway Driving Assist 2.
• Euro NCAP's next results release is 12 October 2026, per its ratings page, so results are added over time rather than all at once.
• Because requirements are updated every three years, per Euro NCAP, a star rating earned under an older protocol is not directly comparable with one earned under a newer one.

To check any of this yourself, look up the specific model on Euro NCAP's ratings pages, where each result states the protocol year it was rated under and the equipment specification tested, and read the exact test and assessment procedures Euro NCAP publishes in its protocols section. Per Euro NCAP's ratings and protocols pages, as read on 25 September 2026, the ratings list and the 2026-2028, 2025 and truck and van protocols are the current published versions - both change as Euro NCAP updates them.
