Mazda CX-3 vs Mazda CX-5: Complete 2025 Model Comparison Guide

The Mazda CX-3 and Mazda CX-5 are two of Mazda’s best-selling SUVs, but line them up side by side and the differences go well beyond size.

From performance to packaging, tech to towing, there’s a real decision to make here — and price is just the start of it.

In this guide, we’ll compare the two head-to-head to help you figure out which one makes the most sense for you.

Design & size: Urban agility vs refined space

The CX-3 is Mazda’s smallest SUV, and it wears that title with intent. At 4,275mm long and 1,765mm wide, it’s compact, low-slung, and easy to manoeuvre (perfect if your daily grind involves tight streets, tight car parks, or just a preference for something more nimble). The design still holds up in 2025 with its sculpted lines, short overhangs, and just enough SUV cladding to look tough without going overboard. Inside, it’s neat and focused, but space is tight in the second row and boot.

The CX-5 plays in a different league. It’s 300mm longer and 80mm wider than the CX-3, and that extra size goes exactly where you want it—more legroom, more boot space, and a cabin that feels properly midsize. There’s more road presence, too: broader shoulders, deeper curves, and a confident stance that looks at home in the city or out on the highway. Inside, you’ll find better materials as you step up the range, and enough space in the back row for adults or child seats without compromise.

So, which works better? If you’re after something compact, stylish, and city-ready, the CX-3 nails the brief. But if you’ve got passengers, gear, or plans that stretch beyond the daily commute, the CX-5’s extra size makes a big difference, especially if you’re thinking long-term.

Performance & fuel economy: Efficient daily driver or powerful all-rounder?

Under the bonnet of every CX-3 is a 2.0-litre petrol four-cylinder, driving the front wheels through a six-speed auto. Outputs sit at 110kW and 195Nm, which is modest, but more than enough for the car’s size and weight. The CX-3 weighs in under 1,300kg, so it feels light on its feet around town, with responsive steering and a comfortable ride at low speeds. Fuel use is rated at 6.3L/100km combined, and in the real world, it stays pretty close, especially if most of your driving is urban.

The CX-5 steps things up with more engine options. There’s a 2.0L entry model, but most buyers end up in the 2.5L (140kW/252Nm) or the 2.5L turbo (170kW/420Nm), both available with all-wheel drive. The added grunt is noticeable, especially with the turbo, which pulls strongly with minimal effort. It’s a heavier car, so fuel economy depends on your engine choice: between 6.9L/100km for the base engine and up to 8.2L/100km for the turbo AWD. Not bad for a midsize SUV with real performance chops.

If you mostly stick to the suburbs and want low running costs, the CX-3’s single engine setup keeps things simple and affordable. But if you tow, road-trip, or value a bit of punch underfoot, the CX-5’s powertrain range makes it the more flexible, future-proof pick.

Interior & tech: Everyday essentials vs high-end features

The CX-3’s interior is simple, tidy, and doesn’t try too hard. You get an 8-inch infotainment screen with Mazda’s MZD Connect system, Apple CarPlay and Android Auto, and a decent six-speaker sound system. The dash layout is clean, with physical controls for climate and media, and finishes that punch above the price point (especially in higher trims such as the GT SP and Akari, where you’ll find suede and leather touches). That said, it’s a narrow cabin, the rear seats are tight for adults, and there’s not much in the way of rear charging or air vents.

Step into the CX-5 and things feel much different straight away. You’re looking at a 10.25-inch widescreen display across the range, with built-in satellite navigation, wireless CarPlay and Android Auto, plus an upgraded Bose audio system in higher trims. The materials are a cut above, especially in the Akera with its Nappa leather, LED ambient lighting and heated front and rear seats. It’s a more mature, comfortable space, with proper rear-seat amenities like vents, USB ports and a centre armrest that doesn’t feel like an afterthought.

If you just want a well-built, easy-to-use interior, the CX-3 delivers without fuss. But if you’re after a tech-rich, more refined space for longer drives and passengers, the CX-5 starts to earn its asking price very quickly.

Boot space & flexibility: City errands or family road trips?

Boot space in the CX-3 is modest. With the rear seats up, you get 264 litres, which is enough for a couple of bags, a week’s groceries, or a folded-up pram if you pack carefully. Fold the seats down and that expands to 1,174 litres, but the load height is a touch high and the space itself is fairly shallow. It works fine for light urban use, but we’d say it’s not the car you want to overpack.

The CX-5, on the other hand, offers 438 litres with all seats in place, expanding to 1,340 litres when folded flat. That’s a proper family-size boot, easily swallowing a few suitcases, a pram, or gear for a weekend away. There’s a powered tailgate on higher trims, and a clever two-position cargo floor that adds flexibility. The boot opening is wider too, making it easier to load bulky items without fuss.

If your load consists of shopping bags, gym gear or the odd overnight bag, the CX-3 gets the job done. But if you’ve got school runs, family road trips, or bulky cargo in your routine, the CX-5’s extra boot space (and easier access) will make itself known fast.

In the CX-3, you’ll find essentials like autonomous emergency braking, blind spot monitoring, rear cross-traffic alert, lane departure warning, and driver attention alert standard across the range. Higher trims add front parking sensors and a 360° view monitor, but there’s no adaptive cruise or lane-keep assist.

In contrast, the CX-5 comes loaded with Mazda’s full i-Activsense safety suite, even in entry-level grades. You get adaptive cruise control with stop & go, lane-keep assist, traffic sign recognition, and smart brake support front and rear. GT SP and Akera models also pick up front cross-traffic alert, driver monitoring, and adaptive LED headlights.

If you're a confident driver who wants the essentials, the CX-3 holds its own. But if you’re regularly doing highway kays, hauling kids, or just want maximum tech watching your back, the CX-5 pulls ahead.

Price & value: Entry point or step up?

The CX-3 starts at $32,990 drive-away for the G20 Pure, making it one of the most affordable ways into a new Mazda SUV. For that money, you’re getting LED headlights, radar cruise control, a reverse camera, Apple CarPlay and Android Auto, and a full suite of basic safety tech—all in a neat, city-sized package.

Step up to the CX-5 and the entry-level G20 Maxx comes in at $37,990 drive-away. That extra five grand gets you a larger vehicle with a 10.25-inch infotainment screen, wireless phone mirroring, better interior materials, more space in every direction, and stronger resale demand. The CX-5 also unlocks future flexibility, such as towing, AWD, and turbo options.

In pure numbers, the CX-3 wins on affordability. But in terms of value for space, features, and long-term versatility, the CX-5 makes a solid case for spending the extra, especially if you’re planning to hold onto it for a few years.
