Mazda CX-8 VS Mercedes-Benz GLB-Class

The CX-8 is a very practical family hauler because there's ample room in all three rows. Yes, even adults will be able to squeeze into that third row without too many complaints!

All rows enjoy well-cushioned seats and up front they are electrically adjustable, but unfortunately, only the driver's side has lumbar support.

The middle row can slide forward manually or by using the electric button found on the side of the seats... but doing it yourself is way faster.

They do slide far enough forward that you won't embarrass yourself too much when you have to clamber into the third row. Where the seats have a 50/50 split-fold and manual adjustments (accessed via the boot).

In the first two rows there are lots of individual storage options but the front enjoys the most. The middle console is deep enough to be useful and I like the dual opening lid. Each row gets a couple of cupholders and drink bottle holders, too.

The charging options are great, with each row getting two USB-C ports and the front getting a wireless charging pad and 12-volt socket.

All of the controls and dials feel within easy reach and the 10.25-inch touchscreen multimedia system graphics are clear.

You can use it as a touchscreen or opt for the rotary dial but switching between the two was awkward for me. Especially, since the touchscreen function is disabled when you are using the wireless Apple CarPlay. This also has wired Android Auto, for those users. 

The amenities are practical throughout with a dark headliner, three-zone climate control and heated outboard seats and retractable sun-blinds in the middle row.

Good news for families because there are five top-tether points across the back rows and ISOFIX child seat mounts on the outboard seats in middle row, in case you need them.

You can fit a 0-4 rearward facing child seat and it shouldn’t impact on front passenger comfort. 

My six-year old found it super easy to get in and out of this car because of the 205mm ground clearance and wide door apertures. He enjoyed the high seating position, too, but was disappointed he couldn’t see out of the sunroof!

The boot space is a bit cramped with all three rows are in use at 209L but folding the third row opens up a more respectable 775L - perfect for the average family and its stuff!

The loading space is level, with the temporary spare tyre and clever storage compartments housed underneath. There is a retractable cargo blind and net, luggage anchor points and a 12-volt port, too. 

And, as always, I love a powered tailgate, which this has!

The GLB's thematic purpose in the Benz family is to be the practical option to the upcoming GLA's 'sportiness' and larger GLC's luxury. Although it's not that much smaller than the GLC, the GLB is packaged in a radically different way.

For one, it can be had as a seven-seater, and at this size there's not much that can compete in the luxury space. Again, that makes its closest rival the Land Rover Discovery Sport which is dimensionally similar and also offered with seven seats.

The next closest seven-seat competitors come in the form of the VW Tiguan Allspace and perhaps Skoda Kodiaq.

Audi and BMW don't quite have anything like it (despite fielding a Q2 and Q3 or X1 and X2 respectively... ), and that could well be the GLB's master stroke. It almost fills its own niche. Mercedes is heavy on the idea that this will be the perfect SUV in its line-up for growing families.

Like those VW group rivals, the GLB is a bit of a practicality wizard, too, able to make use of a huge 500-litre boot with the rear seats stowed, or 570 litres as a five-seater.

The second row is on rails, so you can either max legroom or max boot space respectively. I was genuinely surprised with how spacious the third row is.

The packaging is brilliant, I can fit in there, not only with my head completely upright (just touching the roof), but also with actual knee room! The second row seats are also designed as such that your feet can tuck under them, so you don't feel squashed.

Even with another adult in the rear row it's wide enough to not cause problems.

Keep in mind though, with all three rows deployed you'll almost be sacrificing 100 per cent of that massive boot. I couldn't even fit a basic duffel bag in the shelf of space left over.

The second row offers simply heaps of legroom for passengers, even with adults in the third row, and it's surprisingly wide and deep. I found the panoramic sunroof, fitted to some launch cars, ate into the headroom, although it was still more than enough.

Up front is upright, but comfortable in all grades, with the GLA 35 having the most comfortable seats, by far. There are a few trenches strewn about the place, decent cupholders and a centre console box which hosts USB ports.

Trim quality was a notch above the A- and B-Class across the dash, mainly thanks the the choice of materials in the GLB's design.

I do have a few minor issues with visibility though. The A-pillar is upright and, at times, takes up too much of your line-of-sight, especially when approaching corners.

In my seating position, the top of the steering wheel obscures bits of the digital dash, and vision out the back was okay but not stellar thanks to the GLB's almost flat rear window.

Benz' digital dash suite is capable of almost everything that Audi's benchmark 'Virtual Cockpit' does, although using it is a bit awkward, with many sub menus and odd touchpads for flicking through them on the steering wheel.
