Mazda CX-30 VS Renault Koleos

At just under 4.4m long, close to 1.8m wide and little over 1.5m tall (with a 2655mm wheelbase) the CX-30 is in the middle of the pack it competes with in terms of key dimensions.

And space up front is more than adequate, with an impressive feeling of roominess for a relatively small SUV.

For storage, there’s a large lidded box (which doubles as an armrest) between the front seats as well as a pair of cupholders in front of the gear-shifter with a bay for wireless device charging ahead of that.

The glove box is big, there are bins in the doors with room for decent size bottles and a drop-down tray for sunglasses sits overhead.

Move to the rear and the amount of space on offer is surprisingly generous. Sitting behind the driver’s seat, set for my 183cm position, I have plenty of head and legroom, although three full-size adults across the back seat will be an uncomfortable proposition for anything other than short trips. A trio of up to mid-teenage kids will be fine.

Adjustable air vents at the back of the front centre console are a welcome inclusion for back-seaters and storage runs to a map pocket (weirdly, on the back of the front seat only), a pair of cupholders in the fold-down centre armrest and bins in the doors with room for smaller bottles.

In-cabin power and connectivity includes two USB-C outlets and a 12-volt socket in the front centre storage box. No USBs specifically for those in the rear, which is a miss for road trips and no 12V in the boot which can be handy when camping or picnicking.  

Speaking of the boot, cargo volume with the rear seat upright is okay for the class at 317 litres, which expands to a healthy 1479L with the 60/40 split-folding backrest lowered. For comparison the Kia Seltos coughs up 433L with the rear seat upright.

The space is illuminated, there are tie-down anchors to help secure loose loads and there’s a space-saver spare sitting under the floor.

And if you’re keen on towing a tinnie or similar you’re good to go for a 1200kg braked trailer (600kg unbraked).

It might lack the up-to-date styling of those rivals, but the Koleos is practical and spacious inside and great for family duties.

As with the outgoing fourth-generation Nissan X-Trail, the Koleos is one of the larger offerings in the medium SUV segment, and it’s evident when sitting in the front or rear seating row.

Rearward visibility could be better, with a small rear screen and thick C- and D-pillars impeding vision and creating a blind spot.

The front seats are well supported and comfortable and while the driver’s side is power adjustable, the front passenger seat is manually adjustable.

It has a deep central storage bin with a hidden shelf for coins and more. The Koleos features a sizeable glovebox and good bottle storage in the doors, with room for other items.

There’s a weird fixed cup holder in the centre console. It’s not adjustable and there’s room for two very narrow cups and two larger, but not wide, cups. It’s strange. Interior designers could have used that space better.

The CVT's position indicators are located to the left of the shifter and are thus obscured, so you have to rely on the instrument cluster display to confirm what gear you want. 

The steering wheel looks and feels good, but the controls aren’t super logical. There are old school switches in the console to activate the cruise control and speed limiter, but then to adjust and reset the speed you have to hit buttons on the wheel that are not clearly marked. 

The audio controls are housed on a panel-like stalk to the right side of the steering column, which isn’t ideal. These make more sense if they’re housed on the wheel itself. 

Along with a number of cars we have sampled recently, the Koleos has split analogue and digital controls for the air conditioning. Just integrate it in the screen or have traditional controls - not both!

It has a part-digital instrument cluster which is fine, but there’s no head-up display.

Renault’s 'R-Link' multimedia set-up in the Koleos is old, with dated graphics and a small screen, but the menu layout is clear and logical. 

The Koleos lacks wireless phone charging and it makes do with wired Apple CarPlay and Android Auto. The quality of the Bluetooth and CarPlay phone audio is poor and sounds tinny. 

The proximity key that locks and unlocks the vehicle remotely when you walk towards or away from it works every single time. Many of these systems from other brands are patchy at best but the Renault system is faultless. 

The rear seats recline and fold manually 60/40. They’re also surprisingly comfortable. There’s enough bucketing to sink in a bit, and the seats are set high up so kids can easily see out windows.

Space is ample in the second row, with loads of head, leg, toe and knee room, even behind my six-foot (183cm) driving position.

The rear pew has ISOFIX points on the outboard seats, lower air vents, a 12-volt outlet, map pockets, a centre folding armrest with two cupholders, but no USB ports. You have to make do with the two ports at the front.

Open the power tailgate and you’ll find a decent 458-litre boot with all seats in place (maximum 1690L), which is off the pace of its cousin, the Nissan X-Trail (565L), as well as the Toyota RAV4 (580L) and Hyundai Tucson (539L).

A 17-inch steel spare wheel is housed under the boot floor which might explain the lower boot capacity, and there are handy tie-down hooks, a couple of smaller storage nooks and a solid cargo blind.
