Mazda Could Be Building a New Crossover Between the CX-30 and CX-50

Mazda’s crossover family is already a tongue twister of numbers, and the brand looks ready to add one more. A fresh paperwork move with the U.S. Patent and Trademark Office suggests another small SUV could be on the way, tucked neatly between two of the company’s most popular models.

• Mazda registered the CX-40 nameplate with the USPTO on February 27, 2026
• The model would likely sit between the subcompact CX-30 and the larger CX-50
• Separate trademarks for CX-10 and CX-20 hint at even smaller crossovers

What the Trademark Actually Tells Us

Mazda has filed a U.S. trademark for a new model called the CX-40, and the name would slot between the existing CX-30 and the larger CX-50. The filing was registered on February 27, 2026. That’s the easy part. The harder question is whether a real vehicle ever shows up in dealer showrooms, or if Mazda is simply parking the name on a shelf for safekeeping.

Automakers do this all the time. The CX-40 name has actually been trademarked in Australia since 2019, and neither filing confirms a production vehicle, since automakers commonly protect names that never reach showrooms. Still, the timing is interesting given how aggressively Mazda has been expanding its SUV roster.

A Crowded Crossover Family Tree

In the US, Mazda already sells the CX-30, CX-5, CX-50, CX-70, and CX-90, while in other markets it also offers the CX-3, CX-6e, CX-60, and CX-80. Most of them look very similar, and it can be tough to tell one from the other. Adding a CX-40 to that mix risks more confusion at the showroom, but Mazda clearly thinks there’s white space worth claiming.

A CX-40 could lean stylish rather than rugged. One possibility would be for it to adopt a lower profile and roofline, similar to the old CX-4 that Mazda introduced in 2016 exclusively for the Chinese market, which looked like an interesting cross between an SUV and an estate. That kind of coupe-flavored shape would set it apart from the more upright CX-30 and the outdoorsy CX-50.

Why Bother With Another Compact?

Sales numbers tell part of the story. Mazda introduced the subcompact CX-30 in 2019, and according to data from gcbc.net, sales of the model in the United States are currently falling, with first quarter 2026 dealer sales of 7,898 units, which was 62.4% lower than in the same period last year. Meanwhile, Mazda sold 29,034 examples of the CX-50 in the United States in the first quarter of this year, a 24.6% increase compared with the first three months of last year. A new mid-size compact could help Mazda recapture buyers slipping away from the CX-30 without eating into CX-50 sales.

It would also drop Mazda into one of the most cutthroat parts of the market. That puts it up against the Toyota Corolla Cross, Chevy Trax, and, if it ends up a tad larger, the Toyota RAV4 and Honda CR-V. Shoppers typing “Hyundai Tucson for sale near me” into a search bar are exactly the crowd Mazda would want to pull, since the Tucson sits right in that sweet-spot compact zone where buyers cross-shop relentlessly on price, features, and warranty.

Smaller Siblings Could Be Coming Too

The CX-40 isn’t the only fresh name on file. The brand has also filed to trademark the CX-10 nameplate, which could conceivably be used by a pint-sized model, perhaps similar in scale to the Hyundai Casper Electric, also known as the Inster in some markets. Curiously, there was also a trademark for CX-20, though it was filed way back in 2020.

The CX-10 could become Mazda’s smallest SUV, possibly inspired by the Mazda Vision X Compact Concept shown in 2025. Mazda recently invested heavily in its facility in Thailand to build more compact hybrids, and the car that could be called CX-10 or CX-20 could be made there. Put it all together and Mazda’s product map could soon look more crowded than ever.

What to Watch For Next

For now, none of this is confirmed. Mazda has not announced a CX-40 for Canada, the U.S., or any other market, and key product details, including platform, powertrain, production location, dimensions, and launch timing, remain up in the air. If the CX-40 does graduate from paperwork to production, expect hybrid power, a sleeker silhouette than the CX-50, and pricing that nudges right up against Toyota, Honda, Hyundai, and Kia rivals. Mazda has been on a roll with premium-feeling interiors, and a coupe-style compact would give the brand a stylish answer in a segment that often plays it safe.

Buyers shopping the compact SUV space should keep an eye on Mazda dealer announcements in the next year or two. Whether the CX-40 turns into a real product or stays a placeholder, the trademark itself shows the brand isn’t done growing its crossover lineup.
