Kia Stonic VS Mazda CX-3

SUVs should be practical regardless of how small they might be. So along with enough room to seat five people, the Stonic and Venue have to be functional, versatile and have a reasonably sized boot.

Well, let’s start with the boots - both have impressively large cargo capacity for SUVs this small. The Stonic’s boot volume is 332 litres, while the Venue’s is 355 litres. 

In the video of this comparison, we show how only the Venue’s boot can fit all the CarsGuide luggage and have its tailgate closed. We had to remove the Stonic’s cargo shelf to fit the same amount of luggage.

That leaves you with a cargo cover you have to either keep in the second row or leave behind.

The Venue has an ingenious solution to that cargo cover problem - a sidling rail which will accommodate the cover flat against the second row seat backs. 

As for cabin storage, only the Venue gets a shelf above the glove box opening, but both SUVs have two cupholders up front and bottle holders in the doors.

The Venue is better for power and charging outlets with two USB ports, a 12V point, and a wireless phone charger up front and two USB ports in the second row. 

The Stonic doesn’t have a wireless phone charger, and along with a 12V outlet, has just one USB port in the front and one in the back.

The Venue also just beats the Stonic for rear headroom and legroom, but I have to say that even at 189cm tall, I can just fit behind my driving position in both and that’s pretty amazing given the tiny size of these SUVs. 

At just under 4.3m long, less than 1.8m wide and a little over 1.5m tall the CX-3’s footprint is squarely city-sized, and no surprise it shares the Mazda2’s 2570mm wheelbase because it’s underpinned by the same platform as the small hatch.

But there’s more than enough breathing room up front and storage options are creative.

Rather than the ubiquitous single storage box between the front seats the CX-3 offers up an adjustable multi-compartment arrangement, with cupholders and bottle retainers ready to flick into position in multiple locations. 

It’s still covered with a padded lid which doubles as an armrest, and there’s also a generous glove box and bins in the doors with space for large bottles, even an overhead drop-down glasses holder.

Move to the back and there’s a surprising amount of head, leg and shoulder room for an SUV of this size. Sure, it’s no limo, but sitting behind the driver’s seat set to my 183cm position, I was pretty comfortable.

Best for two full-size adults in the rear, although a third can squeeze in for short, relatively uncomfortable journeys. Three up to mid-teenage kids will be fine.  

Rear storage includes bottle shaped cavities in the doors, a map pocket on the back of the front passenger seat only (a weird Mazda habit) and dual pop-out cupholders in the fold-down centre armrest.

No adjustable ventilation outlets in the rear, but in a car this compact, their absence isn’t as big an issue as it might be elsewhere.

For power and connectivity, there are two USB-A sockets in the front (one media, one power-only) as well an SD card slot, an ‘aux in’ jack and a 12V outlet. No power options in the rear, which won’t play well with the kids.

With the back seat upright, boot capacity is an okay 264 litres. Enough to accommodate either the largest 124L or the smaller 95L and 36L suitcases from out three-piece set. But not all of them together.

With a bit of not so gentle persuasion, the large CarsGuide pram just squeaked in, but lower the 60/40 split-folding rear backrest and available space expands to 1174L.

Tie-down anchors to help secure loose loads is a plus and a speed-limited space-saver spare sits under the boot floor.

And if you need to hook up a small boat or other lightweight trailer, the CX-3 Evolve is rated to 1200kg (braked) and 640kg (unbraked).
