Mini Cooper VS Kia Rio

This is a Mini. But it’s the roomiest one ever without back doors.

Drop yourself inside one and you’ll be struck by the sheer change going on. Retro familiarity dominated by brash innovation.

Yes, it still has comparatively upright pillars, a centrally-sited circular display and a row of toggle switches within an otherwise sparse fascia, but that’s where the similarities between classic-old and brand-new cease.

All eyes are drawn to the modest 240mm (9.4-inch) central OLED display, which seems overwhelmingly busy at first glance, but becomes clear in design, intuitive in layout and functional to use in no time. BMW’s experience here is industry-leading.

The Mini deploys bright colours and fun symbols to further help operators know what does what, where and why, making this playful and sophisticated in execution. If only all screen-based multimedia and vehicle settings were this logical. So much so, in fact, that even a limited number of toggle switches, alongside the welcome volume knob and gear selector, are enough. You won’t miss them.

Now, the driving position is first class as you might expect, with that sitting-upright-in-a-box-with-plenty-of-glass-all-round-you sensation that’s been part of the Mini experience for decades. And, in Favoured guise, the JCW buckets are superb.

The small, low-placed wheel feels right, forward vision is excellent, nothing is too much of a stretch away, storage is generous for a car this size (with a largish glove box included) and ventilation proved to be reassuringly effective in the Baltic-esque conditions we tested the car in.

Of course, being a Mini, the Cooper boasts personalisation and customisation galore, including for some compelling screen backgrounds (one reminiscent of the Morris era) and the inevitable ambient lighting, while the standard, synthetic trim and textures are amongst the most interesting in any car. And it’s all really well put together in terms of aesthetics and build quality.

What’s not to like?

Well, for starters, the glass roof lacks a cover and that’s daft in Australia. Even on a freezing Melbourne day, the sun’s glare can be too much. The side pillars are a blind spot hazard, making those standard lane-support driver-assist safety alerts essential, so don’t disable them. The between-seat cubby feels flimsy and has a lid facing the wrong way from the driver - that’s just plain lazy, BMW. And we’re glad the head-up display directly ahead of the driver is included because the digital speedo in the centre screen strays too far from some drivers’ comfortable sight lines.

Now, there’s no point complaining about the four-person Cooper 3dr’s rear seat packaging, as there’s a massive hint in this car’s name.

But while there’s sufficient room for two larger people, the two fixed positions are best for kids only. Their backrests are a tad too upright for adult comfort. There are basically no amenities present and the side windows do not crack open. Have carmakers forgotten how? Bare and basic sums it up back there. Oh, and entry/egress is impeded by painfully slow-moving electric front seats and narrow apertures to squeeze through.

Finally, there’s the cargo area, which mirrors the previous versions with a volume of just 210 litres (VDA), rising to about 800L with the 60/40 twin backrests folded. You don’t buy a Mini for practicality. And while there’s hidden storage, no spare wheel exists, remember. Just a fiddly tyre repair kit.

Still, the Cooper’s overall cabin execution is ultra-fresh yet still reassuringly on-brand, with enough interesting new details and technologies to justify updating from an older model. An inside job well done.

I'd argue the key reason to buy the Rio at this end of the market is that it has the most space and largest cabin relative to its rivals, bar maybe the Suzuki Baleno.

All-round practicality is great, with front passengers scoring a low, sporty seating position with a high roof, and so much width in the cabin it almost feels like the Rio belongs in the next segment up.

Storage options up front include a large bottle holder and bin in each of the doors, dual cupholders next to the handbrake up front, and a large storage tray underneath the climate unit. Unlike the Yaris or Mazda2, the Rio features a small armrest console box, which gives a small lift to the ambiance of the cabin.

Back seat passengers are treated to great space for this segment, which feels nice and open courtesy of the large rear windows. At 182cm tall, I have airspace for my knees behind my own driving position, as well as relatively healthy headroom and ample width, which is again more like a car in the next segment up.

Rear passengers don’t get adjustable air vents, but there is a single USB port, a single pocket on the back of the passenger seat, and small bottle holders in each of the doors.

Perhaps the Rio’s biggest drawcard is its boot capacity, which at 325 litres is one of the largest in the city car class. Unlike the Yaris, Mazda2, or Suzuki Swift, the Rio will actually accept the CarsGuide three-piece luggage set with the rear seats up, although the rear view was obscured by the medium case.

Thanks to the boxy roofline, the Rio offers a cavernous 980L with the rear seats folded down, and despite its abundance of room, maintains a space saver spare wheel under the floor.
