Mazda CX-8 vs CX-9 & CX-90: Comparison of Alternative Models

Introduction

The Mazda CX-8 is a car I think would have done better had it been sold in North America, but it never made it there. Built primarily for markets outside the U.S., the three-row crossover offered a useful middle ground between the smaller CX-5 and larger CX-9. For American buyers, however, getting one means looking beyond the standard new-car market, so the more practical alternatives are the CX-9 or its successor, the CX-90.

The same “CX” naming helps explain Mazda’s lineup: “CX” identifies Mazda’s crossover and SUV range, with the number generally indicating where each model sits in the range, even though the global lineup isn’t perfectly consistent.

That leaves an interesting question. Is the CX-8 worth pursuing as an import, or does the CX-9 or CX-90 make more sense? This comparison looks at those alternatives from a buyer’s perspective, including size, engines, fuel use, practicality, and the compromises involved with choosing a model Mazda never sold in North America.

What is CX-8?

The Mazda CX-8 is a three-row crossover designed to give families more passenger space without becoming a full-size SUV. Unveiled in Japan in 2017, it shares much of its DNA with the CX-5, but its long wheelbase enables it to accommodate up to six or seven occupants, depending on the seating layout.

What allures most CX-8 admirers is its relatively manageable footprint. It is easier to manoeuvre on narrow roads and in tight parking spaces than a full-size three-row SUV, yet still gives passengers useful interior space. Higher trims can also offer features such as leather upholstery, heated and power-adjustable seats, a power tailgate and advanced driver-assistance systems.

Available engines vary by market and model year. Depending on specification, buyers can choose between a naturally aspirated or turbocharged petrol engine. Mazda’s 2.2L Skyactiv-D diesel engine is particularly interesting to buyers who value low-speed torque and long-distance fuel economy.

In December 2023, Mazda discontinued production of the CX-8, but its combination of three-row practicality, relatively compact dimensions, and premium-leaning interior remains appealing to enthusiasts, especially as a used import.

Why US Never Got the CX-8: CX-8 vs CX-9 vs CX-90

Even though the Mazda CX-8 was never sold in the US, Mazda had a plan, whereby they offered the CX-9 as an alternative. The CX-9 was built for North America as Mazda’s larger three-row crossover, while the CX-8 was created mainly for markets such as Japan where buyers wanted three rows without the CX-9’s size.

That left the two models with a similar job but different priorities. The CX-8 was a narrower, more manageable alternative for markets where vehicle size matters more, while the CX-9 was better suited to North American market as a large family crossover. Bringing both to the same market would have created unnecessary overlap.

The arrival of the CX-90 changed the picture again. It replaced the CX-9 in Mazda’s North American lineup, but it isn’t simply a CX-9 with a new badge. Its platform, powertrains and positioning are different.

So if you like the CX-8 but live in the U.S., the practical alternatives are a used CX-9 or newer CX-90. The CX-8 remains the interesting import option for buyers willing to accept the extra complications.

What’s the difference with CX?

The “CX” in Mazda’s CX-5, CX-8, CX-9 and CX-90 is Mazda’s nomenclature that identifies the vehicle as part of Mazda’s crossover and SUV range. The number generally indicates the model’s position in the lineup, with a higher number usually meaning a larger or more upscale vehicle. However, Mazda’s numbering is not a strict size scale, so the numbers shouldn’t be viewed as direct measurements.

The CX-8 and CX-80 are a good example. Both are three-row SUVs, but they come from different generations of Mazda’s design and engineering approach. The CX-8 belongs to the same era as the CX-5/CX-9, but was built for markets outside North America. The newer CX-80 belongs to Mazda’s large-vehicle design language and sits alongside models such as the CX-60 and CX-90.

The CX-9 and CX-90 show the change even more clearly. The CX-9 was Mazda’s large three-row SUV for North America, while the CX-90 replaced it. Despite the similar purpose, the CX-90 is based on a newer platform and uses a different drivetrain layout and engine range.

So, the number gives you a rough idea of where a Mazda sits in the range, but the CX-8 is not simply an older version of the CX-80, nor is the CX-9 simply the previous CX-90. The numbering reflects Mazda’s evolving model lineup rather than a direct one-to-one size comparison.

Buying Used: What Goes Wrong and What to Check

A used Mazda CX-8 as a family SUV can be a good idea, but its three-row configuration and optional engines require conducting due diligence.

Start with the engine and service history. On the 2.2L Skyactiv-D diesel, look for evidence of regular oil changes and correct oil specification. Check for excessive smoke, rough running, unusual turbo noise, and signs of oil consumption. The diesel’s DPF and emissions system also deserve attention, particularly on cars that have spent most of their lives doing short trips.

On petrol versions, check for uneven idling, warning lights, cooling-system problems and evidence of poor servicing. A proper diagnostic scan is worthwhile on any CX-8 rather than relying only on the dashboard.

The automatic transmission should shift smoothly when cold and hot. Hesitation, harsh engagement, or unusual noises are reasons to investigate further.

Because the CX-8 is often equipped with i-Activ AWD, test the system rather than assuming it works. Check the AWD warning lights, listen for drivetrain noises, and inspect underneath for leaks or damage.

Finally, test the electronic equipment. Power seats, electric tailgate, cameras, parking sensors, infotainment, climate control, and driver-assistance features can be expensive to repair. Check the third-row seats and folding mechanisms too. A thorough inspection is much cheaper than discovering these problems after purchase.

Writer’s Perspective

If I were in the market for a used three-row Mazda, I would not automatically pick the newest or largest model. The CX-8 makes a lot of sense in countries where it was officially sold or where parts and servicing are readily available. Its rather small footprint compared to the CX-9 and CX-90 is a genuine advantage on crowded streets and narrower roads.

For buyers in East Africa, I would be particularly interested in a well-maintained CX-8 diesel. The 2.2L Skyactiv-D has useful torque and can make sense for someone covering long distances, provided the vehicle has a convincing service history. I would be much more cautious with a neglected diesel than with a higher-mileage petrol car that has been properly maintained.

If you are in the United States, the CX-8 is a harder recommendation simply because it was never officially sold there. A CX-9 is easier to own, while the CX-90 is the better choice if your budget allows.

In a nutshell: buy the CX-8 for its practicality, not otherwise. A clean, well-maintained example is worth considering; a cheap one with an unclear history is not.

Final Verdict

The Mazda CX-8 is an interesting choice for buyers who want three rows without the size of a full-size SUV. Its relatively compact footprint, comfortable cabin and choice of petrol and diesel engines make it particularly appealing in markets where it was officially sold.

The CX-8 also makes sense as a used import, but only when you understand what you are buying. The diesel version can be a good option for long-distance driving, although its DPF, turbo and service history deserve careful inspection. A petrol model may be the safer choice when the vehicle’s previous use is uncertain.

The CX-9 is the more straightforward alternative for buyers in North America, while the newer CX-90 brings a completely different platform and powertrain approach.

The most informed decision would be to choose the best-maintained CX-8 rather than the cheapest one. For the right buyer and market, it remains a practical three-row Mazda thats worth the attention.
