Shopping for a compact SUV means asking a lot of questions — and some of the most important ones are about size. Will it park easily in Racine? Does it have enough cargo room for a Costco run? Is the back seat actually usable for adults? If you’re looking at the 2026 Mazda CX-30, you’re already on the right track. Our team at Frank Boucher Mazda of Racine gets these questions every week, and the good news is the answers are pretty satisfying. Here’s a full breakdown of the Mazda CX-30 dimensions, weight, and performance specs — all in one place.
Key Takeaways
- The 2026 CX-30 measures 173.0 inches long, 70.7 inches wide, and 61.4 inches tall — compact enough to park easily, substantial enough to feel planted on the highway.
- Curb weight runs from 3,395 lbs (non-turbo) to 3,527 lbs (turbo) — a well-balanced number that contributes to its solid, confidence-inspiring feel behind the wheel.
- Interior dimensions are genuinely usable: 41.7 inches of front legroom, 36.3 inches in the rear, and up to 45.2 cubic feet of cargo space with the rear seats folded.
- Both engine options — the 186 hp base and the 227–250 hp turbo — come paired with i-ACTIV AWD and a 6-speed automatic as standard.
- The CX-30 earns a 5-Star NHTSA Overall Safety Rating and a Car and Driver Editors’ Choice Award for 2026.
What Are the Exterior Dimensions of the 2026 Mazda CX-30?
The 2026 Mazda CX-30 has a CX-30 length of 173.0 inches, a Mazda CX-30 width of 70.7 inches, and a Mazda CX-30 height of 61.4 inches. It rides on a 104.4-inch wheelbase with 8 inches of ground clearance — more than most city cars, and enough to handle snowy Wisconsin back roads with confidence.
The CX-30’s length of 173 inches puts it firmly in subcompact crossover territory, which is exactly the sweet spot for drivers who want SUV capability without the headache of parallel parking a full-size vehicle. In a city like Racine — where downtown parking and neighborhood streets keep things tight — that compact footprint genuinely matters. The 70.7-inch width gives the CX-30 a wide, stable stance without encroaching on the next lane, and the 61.4-inch height strikes a nice balance between a low, sporty roofline and practical interior headroom. The 8 inches of ground clearance is a standout for the class. That’s enough to handle gravel lots, light trails, and the kind of unplowed winter streets that are a fact of life in southeastern Wisconsin.

How Much Does the 2026 Mazda CX-30 Weigh, and What Are the Interior Dimensions?
The Mazda CX-30’s weight comes in at 3,395 lbs for the base non-turbo trim and 3,527 lbs for the turbocharged models. That extra CX-30 weight with the turbo is barely noticeable to drivers — but the engine more than makes up for it with up to 250 hp and 320 lb-ft of torque on premium fuel.
Inside, the Mazda CX-30 specs hold up well for a subcompact. Front passengers get 41.7 inches of legroom and 38.1 inches of headroom. The rear seat offers 36.3 inches of legroom and 38.3 inches of headroom. On the cargo side, 20.2 cubic feet behind the rear seat handles a week’s worth of groceries or a couple of overnight bags. Fold those rear seats flat, and you’ve got 45.2 cubic feet — enough for furniture runs, gear-heavy road trips, or anything else life in Wisconsin throws at you.

What Engine and Performance Specs Does the 2026 CX-30 Offer?
The Mazda CX-30 specs include two engine options, both paired with a 6-speed automatic transmission and standard i-ACTIV AWD. The base SKYACTIV-G 2.5L four-cylinder makes 186 hp and 186 lb-ft of torque. Step up to the turbocharged 2.5L and you get 227 hp on regular fuel, or 250 hp and 320 lb-ft of torque on premium, which makes it one of the more spirited options in the subcompact SUV segment.
What makes Mazda’s approach to these engines stand out isn’t just the numbers — it’s the delivery. The CX-30 uses a Dynamic Pressure Turbocharger that builds boost almost immediately, so there’s no lag while the power comes in. For 2026, Mazda added a standard limited-slip differential across the lineup, which improves low-speed handling and traction in slippery conditions — a welcome upgrade for Wisconsin winters.
