Mercedes-Benz GLB-Class VS Hyundai Santa Fe

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.

Not all SUVs are created with equal practicality and even though the Santa Fe and Sorento are much the same in many ways one of these vehicles is more spacious, has better storage and a bigger boot. Oh, and it has two wireless phone chargers, not one.

Yes, it’s the Santa Fe. Not just the more practical one because it’s shaped like a box, although that does have something to do with it. What makes the Santa Fe so much more practical is the interior design with storage more of a priority.

Look at the area under the centre console - there’s a tray big enough for a backpack or handbag. And above it are the two wireless phone chargers, USB ports and cupholders.

There’s the glove box, of course, but above that is a shelf with a grippy surface for keys or wallets and purses. And above that is one of the weirdest contraptions I’ve seen not just in a car, but anywhere - a sterilisation compartment.

It looks like another glove box but it’s actually a space to put anything you want decontaminated - freed from bacteria and germs using UV-C radiation. Stop looking at me like that, I’m serious.

You put your phone in, shut the door, press the UV-C button on the dashboard and 10 minutes later - bing! - your phone is sanitised. Have a look at the video we've made if you still don’t believe me.

The second row of the Santa Fe has excellent legroom, even for me at 189cm tall, and good headroom, too.

For storage, I love the way the centre console box between the driver and front passenger can also be opened from the back by the second row passengers. And below that is a long, deep drawer.

The second row also has door pockets, cupholders and directional air vents, plus USB ports in the sides of the front seats.

Third row seats in SUVs are never the most accommodating for someone my height, but the Santa Fe’s offer good leg and headroom for children. There’s also a USB port on either side along with air vents with fan control and cupholders.

Worth noting the Santa Fe’s large and tall rear doors made putting our toddler into her car seat easier than in the Sorento with its more angular aperture.

The Santa Fe and Sorento have dark-tinted privacy glass for the rear windows and pull-up sunshades.

The six-seat option for the Santa Fe reduces this SUV’s practicality in a couple of ways. Obviously, you lose the capability of carrying seven people, but not being able to have a middle section to slide across to the other side or even just place items on is a problem.

A hire car company might prefer the six-seat option, but if you have a family the seven-seater is the way to go. Not only does it cost less, it's more practical. 

The Sorento is by no means impractical, but compared to the Santa Fe there are fewer storage areas in what feels a more compact cabin.

Up front in the Sorento there’s a wireless phone charger forward of the shifter but it’s in a small hidey hole which makes retrieving the phone tricky.

There are USB ports there, too, as well as cupholders and big door pockets. You won’t find a floating centre console with storage underneath as in the Santa Fe, or shelves and there's no sign of a sterilisation compartment.  

In the second row the Sorento has little buckets in the doors, bottle holders and more cupholders in the centre folding armrest. USB ports are in the sides of the front seats along with power adjustment controls.

There’s good legroom and headroom in the second row,  and directional air vents in the rear of the centre console.

The third row is on the cramped side for me, but most third rows are and they’re really for kids. My eight-year old son wanted me to let you know the windows for back seats in the Sorento are tiny, while the Santa Fe has much larger windows. There are still storage wells, USB ports and fan controls with air vents, though.

The Santa Fe and Sorento both have small cargo capacities when the third row is in place but there's enough space for one carry-on luggage-sized suitcase. With the third-row seats folded flat the Sorento has a volume of 608 litres while the Santa Fe is slightly larger at 628 litres.
