Mazda CX-3 sizes and dimensions guide

Mazda is the latest brand to make an entrance in the mini-crossover segment, in the shape of the CX-3. This sharply-styled alternative to the Nissan Juke and Ford EcoSport has been commended in reviews, but how well will it fit into your life?

We’ve closely studied all the vital statistics to see how big it is on the outside, and how much space there is inside for people and things.

Exterior Dimensions

Compared to its closest rivals, the CX-3 is generally lower and longer, lending the Mazda a sleeker look. Specifically, it’s 14cm longer and 3.5cm lower than the Nissan Juke, while its width is pretty much identical.

If you frequently park in tight spaces, the length might be the only thing to consider, but it’s still a small car overall. Combined with the slightly raised driving position compared to a regular supermini makes the CX-3 easy to drive in towns and cities.

Length 4,275mm
Width 1,765mm
Height 1,535mm

Interior dimensions

Although Mazda hasn’t yet revealed official measurements for the CX-3’s cabin, testers have suggested that, like most cars in the class, the interior can just about cater for four adults.

Taller occupants might complain about rear legroom – particularly if sitting behind someone similarly sized in the front – but this is to be expected from a mini SUV. The interior quality is a cut above many rivals, too.

Boot space

The CX-3’s boot is very similar to that of the Nissan Juke – its 350-litre capacity falls just four litres short of the current class-leader. The Skoda Yeti is the most spacious in the segment at 416 litres, but it’s also a much larger car on the outside, so won’t be as easy to navigate around town.

The opening is wide and square and, although it’s quite high off the ground, there’s no real lip into the boot. It’s worth bearing in mind that the four-wheel-drive system eats into cargo space, reducing it to 287 litres. The fact it costs more, adds weight, blunts performance and decreases fuel economy means only buyers that absolutely need four-wheel drive should tick that box.

Seats down 1,260 litres (4WD 1,197 litres)

Turning circle and fuel tank capacity

Both the CX-3’s turning circle and fuel tank capacity are competitive for the small crossover class. The Suzuki Vitara is able to turn marginally tighter, but it’s hardly a deal breaker.

The 44-litre fuel tank allows a potential range of 683 miles, if you can match the diesel’s official fuel economy of 70.6mpg.

If you want a car to perform at its best, keeping the weight as low as possible will benefit it in almost every way. Less weight means stronger performance, better fuel economy and more responsive handling.

As with many of the CX-3’s measurements, weights across the range fall within those of the Nissan Juke, though the chunkier, simpler Suzuki Vitara is lighter overall.
