Not All Five Stars Are Equal: The Truth About C-NCAP vs Euro NCAP Car Safety Ratings

Picture the scene. You are looking at a Chinese car in a showroom in Germany, the Netherlands, or Australia. Somewhere near the front of the brochure, prominently displayed, is a five-star safety rating. Five stars. Maximum score. The implication is clear: this car is as safe as it gets.

What the brochure may not tell you, and what the salesperson may not volunteer, is that the five-star rating in question was awarded by C-NCAP, China’s own car safety assessment programme, under a test protocol designed for the Chinese market. It is not a Euro NCAP rating. It is not the same standard. And in several meaningful ways, it is not comparable.

This is not about Chinese cars being unsafe. The evidence, which we will examine in detail, shows that the best Chinese export models are now genuinely competitive in Euro NCAP’s demanding assessment framework, with several achieving results that embarrass their European rivals. It’s more nuanced than that, and more important. It is about what a safety rating actually means, who awards it, under what conditions, and why buyers in European and other Western markets need to understand the difference before they treat a C-NCAP five-star sticker as a guarantee of protection.

What Is C-NCAP and Who Runs It?

C-NCAP, the China New Car Assessment Programme, was officially launched in March 2006 by the China Automotive Technology and Research Center (CATARC). CATARC is a government-affiliated comprehensive science and technology enterprise group, established in 1985, with a stated positioning of providing ‘independent, impartial and third-party’ services to the automotive industry. It is not a consumer body like Euro NCAP, and the distinction matters.

The programme was modelled on Euro NCAP and follows a broadly similar structure: vehicles are subjected to a series of crash tests, and the results are expressed as a star rating on a scale of 1 to 5. Since its launch, C-NCAP has been updated every 3 years, with revisions in 2009, 2012, 2015, 2018, 2021, and 2024. Each revision has generally raised the bar, adding new test scenarios and tightening scoring criteria.

The 2021 protocol update, as described by CATARC itself, was ‘the largest revision in C-NCAP history’, incorporating more independent evaluation, more advanced test scenarios, and a stronger focus on active safety. The 2024 revision went further still, making active safety, including advanced driver assistance systems, driver monitoring, and road feature recognition, a central element of the scoring framework.

However, a structural issue has persisted throughout C-NCAP’s history that no protocol update has fully resolved: manufacturers submit their own vehicles for testing and bear the cost of the assessment. This creates an incentive structure that is fundamentally different from Euro NCAP’s, and its implications run through everything that follows.

What Is Euro NCAP and Who Runs It?

Euro NCAP, the European New Car Assessment Programme, presented its first results in February 1997. It is based in Leuven, Belgium, and is, in its own words, ‘established in 1997 and backed by several European Governments, motoring, consumer and insurance organizations.’ Its founding principle, and the one that gives its ratings their credibility, is independence.

When Euro NCAP tests a car, it does not wait for the manufacturer to submit a vehicle. It purchases cars from dealerships anonymously, exactly as a consumer would. The manufacturer has no advance warning of which vehicle will be tested, no opportunity to optimise a specific car for the assessment, and no control over the process. This is not a trivial distinction. It means that what Euro NCAP tests is what you can actually buy, not a factory-prepared showcase specimen.

The Euro NCAP five-star rating system evaluates vehicles across four categories: Adult Occupant protection, Child Occupant protection, Vulnerable Road Users (pedestrians and cyclists), and Safety Assist (driver assistance and active safety systems). Each category carries a percentage score, and the overall star rating reflects performance across all four. In recent years, Euro NCAP has deliberately raised its standards to ensure that five stars remain a meaningful achievement. As Euro NCAP’s Vision 2030 roadmap makes clear, the organisation is committed to continuously raising the bar as vehicle technology advances.

Euro NCAP also operates a policy of rating expiry. A five-star rating awarded in 2018 reflects 2018 standards, which were less demanding than those applied from 2022 onwards, particularly in the Safety Assist category. The organisation is explicit about this: older ratings should not be treated as equivalent to newer ones. This is a point that is frequently overlooked in automotive marketing materials.

Where the Tests Actually Differ

The technical differences between C-NCAP and Euro NCAP are more nuanced than a simple speed comparison suggests. The two programmes have converged in several areas while remaining meaningfully different in others.

Frontal Impact Testing

C-NCAP’s primary frontal test is a full-width perpendicular impact against a non-deformable solid barrier at 55 km/h. C-NCAP also includes a 50 percent overlap frontal impact against a wheeled deformable barrier, in which both the test vehicle and a 1,400 kg barrier platform travel at 50 km/h toward each other, a test that, according to CATARC’s own documentation, is identical to the equivalent Euro NCAP procedure. 

The key difference lies in Euro NCAP’s Mobile Progressive Deformable Barrier test, introduced in its current form in 2020, which creates a combined closing speed of 100 km/h and is designed to replicate real-world car-to-car collisions with particular severity. This is a more demanding scenario than any frontal test in C-NCAP’s current framework.

Side Impact Testing

C-NCAP’s side barrier test uses a 1,700 kg deformable barrier impacting the vehicle at 60 km/h, notably heavier than most international equivalents. Its pole test is conducted at 32 km/h with the vehicle loaded onto a sled at a 75-degree angle, with the cylinder aligned with the test dummy’s head. 

According to CATARC’s protocol documentation, this test is comparable to the Euro NCAP and NHTSA procedures. In this specific area, the two programmes are broadly aligned.

Active Safety and Driver Assistance Systems

This is the area of greatest divergence in recent years. Euro NCAP has placed increasing emphasis on active safety technologies, including autonomous emergency braking, lane-keeping assistance, speed assistance systems, and driver monitoring. The Safety Assist category now accounts for a substantial portion of the overall score, meaning that a car with weak active safety technology cannot achieve five stars regardless of its crash-test performance. 

The 2023 protocol update alone introduced over 100 new active safety scenarios, including Car-to-Motorcycle, Car-to-Car Crossing, Car-to-Car Head-on, Dooring, and Driver State Monitoring. C-NCAP’s 2024 revision has moved in this direction, but the weighting and the specific criteria differ, and a vehicle that scores well on C-NCAP’s active safety assessment may not score equivalently under Euro NCAP’s framework.

Pedestrian and Vulnerable Road User Protection

Euro NCAP’s pedestrian testing is extensive, covering head impact zones across the bonnet and windscreen, upper- and lower-leg impacts, and AEB pedestrian detection across multiple scenarios, including night-time testing and cyclist detection. The Vulnerable Road Users category carries significant weight in the overall score. 

C-NCAP has improved its pedestrian testing in successive protocol updates, and its 2024 revision introduces VRU-AEB tests and passive impact evaluations. But the breadth and weighting of Euro NCAP’s assessment in this area remain more comprehensive.

Rear Occupant Protection

Euro NCAP has placed increasing emphasis on rear occupant protection in its recent protocols, assessing the risk to passengers in rear seats in both frontal and side-impact scenarios. This reflects real-world accident data about where occupant injuries occur. 

C-NCAP has been slower to weigh rear occupant protection as heavily in its scoring, though this gap is narrowing with successive protocol updates.

Test Area	C-NCAP	Euro NCAP
Governance	CATARC (government-affiliated)	Independent, government & consumer-backed
Vehicle sourcing	Manufacturer-submitted & funded	Anonymously purchased from dealers
Frontal wall impact	55 km/h (full width)	50 km/h (full width)
Mobile barrier test	50 km/h per vehicle (identical to Euro NCAP)	100 km/h closing speed (MPDB)
Side barrier weight	1,700 kg at 60 km/h	Comparable speed, lighter barrier
Pole test	32 km/h (comparable)	32 km/h (comparable)
Active safety weighting	Growing — central in 2024 revision	Major component since 2019+
Pedestrian / VRU testing	Improving — expanded in 2024	Extensive, heavily weighted
Rear occupant focus	Increasing	Significant and growing
Rating expiry	Not formally applied	Explicitly acknowledged

The Structural Problem — Who Pays for the Test?

The independence of the testing process is not merely a procedural nicety; it is the foundation on which the credibility of any safety rating rests. Euro NCAP’s practice of anonymously purchasing vehicles from dealerships eliminates the possibility of a manufacturer optimising a specific test car. When a Euro NCAP result is published, you know it reflects the car as it exists in the real market.

C-NCAP’s model, in which manufacturers submit vehicles and fund the testing, creates a different incentive structure. It does not mean that C-NCAP results are fabricated or meaningless. 

Most manufacturers submit genuine production vehicles, and CATARC has protocols designed to ensure test integrity. But the structural incentive to present the best possible vehicle for assessment remains, and its consequences show up in aggregate data.

The statistical picture is telling. The proportion of vehicles achieving five stars under C-NCAP has historically been very high,  consistently higher than the proportion achieving five stars under Euro NCAP in equivalent testing cycles. Several possible explanations exist, including that manufacturers may choose to submit only models they are confident will score well, thereby avoiding the reputational damage of a poor result. Euro NCAP, by contrast, tests what it chooses, and it sometimes chooses to test models that perform poorly, publishing those results as a public warning.

CATARC is aware of this credibility gap. The language in its 2021 protocol announcement, describing the update as offering ‘more independent evaluation’, implicitly acknowledges the issue. The trajectory is positive. But the structural difference in how vehicles are sourced for testing remains, and buyers should understand what it means for the integrity of any C-NCAP result they encounter in marketing materials.

The Rating Inflation Problem

Walk through the C-NCAP results database, and a pattern emerges quickly: an unusually high proportion of tested vehicles achieve the maximum five-star rating. This is not unique to C-NCAP as rating inflation has been a challenge for NCAP programmes globally, and Euro NCAP has responded by repeatedly raising its standards to ensure five stars retains meaning. Its 2022 and 2024 protocol updates made the five-star bar significantly harder to clear, with stronger requirements around active safety technology in particular.

The inflation problem matters most when C-NCAP ratings are used in marketing materials aimed at buyers in markets where Euro NCAP is the relevant benchmark. A consumer in the UK or Germany who sees a five-star safety rating on a brochure will almost certainly interpret it through the lens of Euro NCAP, the rating system they are familiar with and trust. 

If the rating is actually a C-NCAP result, achieved under different structural conditions and different standards, that consumer is being given a misleading impression, even if no individual claim in the brochure is technically false.

Euro NCAP itself is explicit that its ratings strictly apply to vehicles of the specifications offered in Europe. There is a reasonable argument that regulators in European markets should require that imported vehicles carry safety ratings from the assessment programme of the market in which they are sold. For now, the responsibility falls on buyers to ask the right question: which rating system awarded these stars, and when?

Is the Gap Closing?

Here is where the story becomes genuinely interesting, and where the picture for Chinese car brands is considerably more positive than the structural critique above might suggest.

The most ambitious Chinese export brands have not relied on C-NCAP ratings in their push into European markets. They have sought Euro NCAP assessments proactively, submitting their export-specification vehicles to the world’s most demanding independent safety testing programme. And the results have been striking.

In July 2023, Nio became the first manufacturer to achieve five stars under Euro NCAP’s significantly updated 2023 protocol, with both the ET5 sedan and EL7 SUV clearing a protocol that had introduced more than 100 new active safety scenarios. The ET5 scored 96 percent in Adult Occupant protection, the highest of any vehicle tested by Euro NCAP in 2023, as confirmed by both Autocar and InsideEVs.

By the end of 2023, every Chinese car tested by Euro NCAP that year had achieved five stars, nine models across four brands: BYD Dolphin, BYD Seal, BYD Seal-U, BYD Tang, Xpeng G9, Xpeng P7, Nio EL7, Nio ET5, and the Geely-built Smart #3. As Euro NCAP’s own press release noted, these manufacturers were ‘keen to demonstrate that their cars are a match for better-established brands, and the cars released today show that safety is one of the areas where they compete, to the benefit of car-buyers.’

In December 2024, Euro NCAP confirmed five-star ratings for two further Chinese arrivals: the Deepal S07 and the Leapmotor C10, alongside the Maxus eTerron 9 electric pickup. Across the full 2024 testing year, Euro NCAP noted that eight of the 41 cars tested were from leading Chinese brands, including Zeekr, Maxus, Nio, Xpeng, Deepal, and Leapmotor, and that ‘new market entrants swiftly adjusted to the new five-star requirements and provided excellent levels of safety.’

This is not a minor footnote. It represents a fundamental shift in what Chinese cars are capable of, and how seriously the leading Chinese export brands take safety as a competitive credential in Western markets. The gap between C-NCAP and Euro NCAP standards is real, but the best Chinese export models are not relying on C-NCAP to make their case. They are clearing the Euro NCAP bar with a genuine margin.

What Should a Buyer Actually Do?

Given everything above, here is the practical guidance that matters if you are buying a Chinese car in Europe, Australia, or any market where Euro NCAP is the established safety benchmark.

Always look for the Euro NCAP rating

If a car is sold in Europe and has been assessed by Euro NCAP, that is the rating you should look at. Euro NCAP’s full ratings database is publicly available and searchable by make and model. If a vehicle does not appear in the database, that is meaningful information in itself. It may mean the model is too new to have been tested, or that the manufacturer has not sought a Euro NCAP assessment.

Check the year of the rating

Euro NCAP’s standards have increased significantly over time. A five-star rating in 2018 was earned under criteria less demanding than those applied from 2022 onwards, particularly in the Safety Assist category. When comparing vehicles, check that the ratings you are comparing were earned under the same or similar protocol generation.

Do not dismiss C-NCAP entirely

A strong C-NCAP result, particularly under the 2021 or 2024 protocols, is not meaningless. It tells you that the car has passed a real set of crash tests conducted by a legitimate testing organisation. The criticism is not that C-NCAP is fraudulent; it is that it operates under different structural conditions and different standards than Euro NCAP, and should not be presented as equivalent to a Euro NCAP result in markets where Euro NCAP is the relevant benchmark.

Look at the standard safety equipment

Independent of star ratings, check whether the specific variant you are buying includes autonomous emergency braking, lane keeping assistance, blind spot monitoring, and rear cross-traffic alert as standard. 

These technologies have proven real-world safety benefits. Their presence or absence tells you something important about how a manufacturer has prioritised safety across its range, not just the variant submitted for testing.

What Next?

The star rating on a car’s brochure is only as useful as your understanding of what it actually measures. C-NCAP and Euro NCAP are not the same programme, do not operate under the same structural conditions, and do not apply identical standards. For buyers in European or other Western markets, a C-NCAP five-star rating should be treated as background information rather than the primary safety credential.

The good news is that the leading Chinese brands selling into European markets have largely stopped relying on C-NCAP to make their safety case. They are seeking Euro NCAP assessments, clearing the bar with strong scores, and in several cases setting new benchmarks for adult occupant protection. The Nio ET5, the BYD Seal, the BYD Dolphin, and the Deepal S07 are not just safe cars by Chinese standards. They are demonstrably safe cars by any standard.

Manufacturers’ responsibility is to be transparent about which rating applies to which market and model year. Buyers’ responsibility is to ask the question. And the responsibility of publications covering this industry, including this one, is to make the distinction clear every time it matters. Which is every time a C-NCAP rating appears in a brochure aimed at a European buyer.

Editor’s Take

A number of Chinese cars carry both C-NCAP and Euro NCAP ratings, and the honest verdict is this: the structural gap between the two programmes is real, but the narrative that Chinese cars are inherently unsafe is no longer defensible. It was never really the right frame, even when it had more supporting evidence than it does today.

What concerns me more than the differences in test protocols is the marketing behaviour. I have seen Chinese cars sold in European markets with C-NCAP five-star ratings displayed in a way that is clearly designed to be mistaken for Euro NCAP results. 

That is a choice. And it is a choice that undermines trust in Chinese brands at exactly the moment when the product quality justifies building it. The brands doing this are making a short-term calculation that damages the segment’s long-term reputation.

The brands that have gone out and earned their five stars from Euro NCAP,  BYD, Nio, Xpeng, Leapmotor, and Deepal deserve credit for doing it the hard way. The Nio ET5, topping Euro NCAP’s adult occupant protection rankings in 2023, was no fluke. These companies took the testing seriously, built the product to pass it, and have the receipts to prove it. That is the standard every Chinese brand should be held to in export markets. And consumers should demand nothing less.
