Mercedes-Benz GLB-Class vs Hyundai Santa Fe

What's the difference?

It’s easy to say the GLB35 doesn’t deserve to be called an AMG when looking at its credentials on paper, but get behind the wheel and it’s evident Affalterbach played a key role in making it feel as special to drive as it should be.

The GLB35 has all of the great qualities of the GLB250 and other GLB variants, but successfully adds a performance focus to make for an even more compelling package.

Indeed, the GLB35 proves you can pretty much have it all.

So I asked at the beginning if the Hyundai Santa Fe FWD petrol offered enough for families looking for a large seven-seat SUV and the answer is: YES!

It's practical, has people-mover space and storage and is downright comfortable to drive. There's so much to like here.

With the boxy and therefore rugged-looking GLB laying some great foundations, it’s no surprise the GLB35 looks pretty damn good – to these eyes, at least.

Being an AMG model, it stands out from the crowd with an aggressive body kit, with the chunky bumpers, aerodynamic roof spoiler and racy rear diffuser all unique alongside the now-signature Panamericana grille insert.

A set of 20-inch alloy wheels with 255/40 tyres ups the ante at the side, where the carryover black plastic wheel-arch and skirt cladding serves as an obligatory reminder that this is an SUV.

Also of note are the nicely designed LED headlights and tail-lights, which literally light the way, but there’s no getting past the bespoke diffuser element, which integrates the sports exhaust system’s dual 90mm tailpipes.

Inside, the GLB35 is a technological tour de force, with a pair of 10.25-inch high-resolution displays proudly sitting side by side atop the dashboard, with one the central touchscreen and the other the digital instrument cluster.

Both are powered by Mercedes-Benz’s MBUX multimedia system, which arguably remains the best there is today thanks its speed and breadth of functionality and input methods.

The GLB35 is also properly premium. Lugano leather upholstery covers the seats and armrests, while Nappa trims the sports steering wheel. Even the door shoulders and inserts get ‘cow hide’, although theirs is of the artificial variety.

Soft-touch materials are used for the upper dashboard, leaving hard plastics to the lower sections, which is what you’d expect for the price.

While the black headliner makes for a dark cabin, brightness comes from the metallic trim used throughout, notably on the steering wheel, dashboard, doors and centre console. And let’s not forget the pop of colour provided by the addictive ambient lighting.

And mercifully, scratch- and fingerprint-hungry gloss-black accents are limited to the surrounds of the turbine-style front air vents, dual-zone climate controls and centre console.

Unique to the GLB35 are Carbon Structure trim and stainless-steel sports pedals, just in case you forgot you weren’t driving a regular GLB.

It's boxy and bold and you certainly won't mistake it for anything else on the road. That's both good and bad.

The front works beautifully; pairing a chunky and square aesthetic with cool H-shaped LED headlights (a running motif throughout the car). The front and sides look like the chiseled face of a Greek hero or the latest Romantasy crush, but the rear is just awkward. It's essentially just a big blank body panel and the only interesting thing about the back are the H-shaped tail lights.

Head inside and the interior is exactly the same as the base FWD hybrid variant - you get an interesting black and grey tartan fabric upholstery across the seats, and enough soft touchpoints scattered throughout to stop you looking too hard at the heavy use of plastics.

The dashboard shares similar chunky proportions with the exterior and you can see lots of H shapes in the air vents and panelling, so it flows pretty well inside.

The highlight is 100 per cent the large curved panel on the dash that houses the dual 12.3-inch displays. They look high-end and instantly lift the cabin from feeling 'basic'.

Joinery is flush, nothing rattles and there's an overwhelming sense of high-build quality inside. It's a cabin you'll be able to spend a lot of time in.

Measuring 4650mm long (with a 2829mm wheelbase), 1845mm wide and 1660mm tall, the GLB35 is more like the GLC43 in size than the GLA35, making it a mid-size SUV despite its small underpinnings. And that is good news for practicality.

Cargo capacity with the 50/50 split-fold third row stowed is more than solid, at 565 litres (VDA), but it can be increased to a cavernous 1800L with the 40/20/40 split-fold middle bench also not in use. If six or seven passengers are onboard, though, there’s very little room to move.

Nonetheless, the boot is still well packaged, featuring a huge aperture, no load lip, and a flat floor, which make loading and unloading bulkier items a hell of a lot easier. And even the load cover can be stored underfloor when out of action. How good.

There are also four tie-down points, two bag hooks, a side storage net and a 12V power outlet on hand to make matters even easier, while the rear seats can be stowed from the boot.

While we’re on the topic, Mercedes-Benz says the third row can accommodate passengers up to 168cm tall, with the middle bench able to slide fore and aft by up to 140mm.

Yes, I'm too tall, at 184cm, but I can still sit in the very back, although not in total comfort. All in all, about a centimetre of legroom and negligible headroom and toe-room are on offer there for me.

That said, getting in and out in the first place is the real challenge here, with the middle bench unable to tumble forward for easy ingress and egress. Yep, you’re not going to look smooth either way. Children can deal with it, but adults won’t be thrilled.

Therefore, the middle bench is the place to be, even when it’s slid all the way forward. Behind my driving position, it offers about a centimetre of legroom, but this can be increased to several inches by sliding it all the way back.

Either way, plenty of toe-room is available alongside more than an inch of headroom. The latter is more impressive when you consider that’s what you get with the standard dual-pane panoramic sunroof fitted.

Even better, the second row can seat three adults at a pinch, partly thanks to the low transmission tunnel, which means there’s the right amount of space for six fully grown feet across the two footwells. It goes without saying children will again be fine.

Speaking of which, four ISOFIX and five top-tether anchorage points are on hand for fitting up to four child seats across the second and third rows, which makes the GLB35 a serious option for families that like to be sporty.

There are plenty of in-cabin storage options, with the large central storage bin featuring a pair of USB-C ports, while the glovebox is also quite useful, even if it is oddly shaped. And there’s also a sunglasses holder in front of the rearview mirror.

The centre console’s cubby isn’t really designed for storage, with it basically taken up by two cupholders, another USB-C port and a wireless smartphone charger.

The front door bins can accommodate one small and two regular bottles each, which is great, while their rear counterparts can take one small and one regular apiece.

Second-row occupants also have access to a fold-down armrest with another pair of cupholders, but being of the retractable variety, they’re flimsy.

These passengers also have two USB-C ports, with the pair folding out below a small cubby and air vents, which are found at the back of the centre console. Storage nets are also fitted on the front seat backrests.

And don’t worry; the third row gets in on the action, with two cupholders (one regular, the other small) splitting the seats, which have individual USB-C ports and device straps to the sides.
 

I've said it before but I'll say it again. The cabin offers similar, if not the same, level of practicality of a people mover with passenger space and storage solutions.

In fact, Hyundai may have shot their other three-row SUV, the Palisade, in the foot here because I'm not sure why you'd now bother forking out an extra $13,800 on the base Elite grade over out test model. Not when each row will be comfortable for an adult and feature decent amenities.

With seats that don't sit too high and a 177mm ground clearance, the Santa Fe is an easy SUV to get in and out of, even for kids.

The front- and middle-row seats are the most comfortable when it comes to padding and under-thigh support. The powered drivers seat also offers adjustable lumbar support on top of the heat functions that both front seats get.

Storage is top-notch with lots of cubbies to choose from up front with dual gloveboxes, one that can fit a manual and one that will hold smaller items like a wallet, wet wipes etc.

The middle console is huge and has a removable shelf but is also shared with the middle row as the bottom pulls out into a storage drawer for them. This means you can cut out the middle man (AKA the parent) and have a handy place to put any roadie snacks.

The centre console features two phone cradles and a large shelf underneath that easily holds a handbag or Saturday night's takeaway.

There are a total of 12 cupholders (2/6/4) and four drink holders (one in each door storage bin) plus a sunglasses holder and map pockets on the back of the front seats. So, definitely spoiled for choice when it comes to individual storage.

The technology is easy to use and high-quality with display screens that feature crisp graphics and a responsive multimedia touchscreen. The system features wireless phone mirroring for Apple CarPlay and Android Auto, as well as Bluetooth connectivity.

Charging options are good throughout the car with six USB-C ports (2/2/2), and a 12-volt socket and wireless charging pad up front.

Rounding out the cabin is the large boot which offers 642L when the third row is stowed, and up to 1963L when just the front seats are in use.

The loading space is level but you still get a handy under-floor compartment for small items. And the full-size spare tyre and powered tailgate are always practical to have!

The Hyundai Santa Fe is offered in three grades, with the base- and mid-spec options now having the option of having a turbo-petrol engine or a self-charging hybrid powertrain.

Our test model is the front-wheel-drive base-petrol grade, which is priced from $53,000 before on-road costs. That makes it the most affordable variant in the Santa Fe line-up, being $2500 more affordable than the base FWD hybrid model.

This positions it in between its three-row large SUV rivals, the Kia Sorento S ($50,680) and even larger Nissan Pathfinder ST-L ($60,220). But the Sorento is still offered with a choice between V6 petrol engine and a four-cylinder turbo-diesel engine, which will entice some.

Our test model is incredibly well-equipped for a base variant and includes features like heated front seats, a powered driver's seat (with adjustable lumbar support), rear privacy glass and LED external lights.

There are great practical items like a full-size spare wheel, a powered tailgate, keyless entry/start, a 360-degree camera system, dual-zone climate control and tyre pressure monitoring.

Technology is also a standout with dual 12.3-inch displays taking centre stage, FM/AM and digital radio, wireless Apple CarPlay/ Android Auto, Hyundai 'Bluelink' app, over-the-air updates, Bluetooth connectivity, a wireless charging pad, six USB-C ports and two 12-volt sockets.

Bluelink connected car services brings features like ‘Automatic Collision Notification’ an emergency call (SOS) function, geo-fencing, valet, speed and time alerts and more.

The GLB35 is powered by an uprated version of the GLB250’s 2.0-litre turbo-petrol four-cylinder petrol engine, with the AMG-fettled version producing a more substantial 225kW of power from 5800-6100rpm and 400Nm of torque from 3000-4000rpm (up from 165kW/350Nm).

This version is also matched to an eight-speed dual-clutch automatic transmission as well as Mercedes-AMG’s front-biased but fully variable 4Matic all-wheel-drive system.

Thanks to this combination, the GLB35 can sprint from 0-100km/h in just 5.2 seconds with launch control enabled, while its electronically limited top speed is 250km/h.

Our Santa Fe is the front-wheel-drive base variant, which features an eight-speed dual-clutch auto transmission and a 2.5-litre four-cylinder turbo-petrol engine that produces up to 206kW of power and 422Nm of torque.

Our model has a braked towing capacity of 2000kg, which is up from its hybrid siblings which can only tow up to 1650kg.

The GLB35’s fuel consumption on the combined-cycle test (ADR 81/02) is 8.3L per 100km, while its carbon dioxide emissions are 186 grams per km. All things considered, both claims are pretty decent.

In our real-world testing, though, we averaged a high 14.1L/100km over 75km of driving split between highways and country roads, so not your typical mix, then. A heavy right foot also played into that result, so expect a better return after a regular run.

For reference, the GLB35’s 60L fuel tank can be filled up with 98RON petrol at minimum.

The base petrol Santa Fe has an official combined fuel cycle usage of 9.3L/100km and 67L fuel tank, giving it a theoretical driving range of 740km, which isn’t as good as its hybrid siblings but still sufficient for the odd road trip.

After doing lots of open-roading this week and a good three days of city dwelling, my real-world usage has popped out at 8.7L/100km, which is a solid result for such a large SUV.

Don’t let the GLB35’s family friendliness fool you, this is an SUV that can get up and go.

The engine’s extra power and torque over the GLB250 are immediately felt behind the wheel, with the GLB35 accelerating with the vigour of an all-wheel-drive hot hatch, which makes sense given their similar claims.

And if you have one of the sportier drive modes engaged, the booming noise generated is also special – even if a lot of it is of the artificial variety, pumped into the cabin to make occupants feel like things are getting serious.

What is genuine, though, is the well-rounded transmission, which is characteristically quick with its upshifts. At the same time, it’s also relatively smooth, even at low speed, which has proven to be a challenge for dual-clutch units over time, but not here.

To earn the AMG badge, the GLB35 goes even further with other mechanical upgrades, including sports tunes for the suspension and steering.

Specifically, the GLB35’s independent suspension set-up not only consists of MacPherson-strut front and trailing-link rear axles with adaptive dampers, but also introduces new steering knuckles, transverse control arms on the front axle, and a stiffened subframe.

The resulting ride is actually quite good. Yes, the extra firmness over the GLB250 is noticeable – particularly in the sportier drive modes that stiffen the adaptive dampers all the way – but it’s by no means a deal-breaker.

That said, it’s worth noting our test vehicle was fitted with the optional 21-inch alloy wheels ($1990), so the GLB35’s like to ride even better on its standard package.

This is remarkable considering the handling improvements made, with the GLB35 managing body roll and pitch better than the GLB250 when pushing hard into and around corners, coming out of which grip is plentiful thanks to the all-wheel-drive system.

Thankfully, the standard-fit high-performance braking package consisting of 350mm front and 330mm rear discs with four- and one-piston callipers respectively helped it wash speed away with ease when attacking the twisty stuff with intent, even with 1857kg (kerb) to deal with.

Also on hand is electric power steering, which is speed-sensitive and has a variable ratio in the GLB35. Basically, it’s quicker when you want it to be, remaining on the lighter side in hand until you engage one of the sportier drive modes and weight is increased markedly.

The petrol engine definitely has more pep to it than the hybrid variants I've sampled. The power is responsive and you still feel like there’s heaps leftover when you have to overtake or get up a hill without any annoying engine whines.

The steering isn’t too heavy, despite the size of this car but turning off the lane-keeping aid will keep the on-road experience feeling smooth. Otherwise, you sort of ping-pong in your lane as the aid readjusts strongly.

All Santa Fes feel way more nimble than they have any right to in corners. You do get some roll, but our test model is sure-footed, even in heavy wet weather. 

The eight-speed dual-clutch auto transmission is smooth enough and you don’t get any annoying lags when you accelerate from a full stop, which is unusual for such a unit.

Ride comfort is pretty high as well, with suspension that feels forgiving over the worst of the bumps and a cabin that remains quiet, even at higher speeds. 

You have really great visibility in this model because of how big the windows are and the taller driving position helps as well. None of the pillars hindered my vision either from my driving position.

The Santa Fe well and truly fills out a car space and it was easy to see it in a car park because the butt hangs out a bit, but it’s still easy to park with its very clear 360-degree camera system and parking sensors at the front, side and rear. So while it is big, it doesn't feel big to park.

Overall, the petrol Santa Fe is an simple SUV to drive and will be a forgiving choice for lots of different driving styles.

All hybrid Hyundai Santa Fe variants are covered by a maximum five-star ANCAP safety rating from testing done in 2024, but the petrol variants are not, so our test model is currently unrated. It does feature 10 airbags, though, which is excellent for a family SUV and the curtain airbags extend to the third row.

The standard safety equipment includes blind-spot monitoring, LED daytime running lights, driver attention alert, leading vehicle departure alert, safe exit assist, rear occupant alert (first two rows only), rear collision warning, forward collision warning, rear cross-traffic alert, lane departure alert and a lane-keeping aid.

There's also lane following assist, traffic sign recognition, an intelligent seatbelt warning (first two rows only), adaptive cruise control (with start/stop), the 360-degree camera system and front, side, and rear parking sensors.

It's also nice to see the blind-spot monitor on the base model, which is a system that pops a video feed of your blind spot onto your dashboard.

However, some of the safety features, like the driver attention monitor and traffic sign recognition, can be intrusive to daily driving. If you could permanently disable the sound alert, it would be a lot more enjoyable to drive long term.

As with all Mercedes-AMG models, the GLB35 comes with a five-year/unlimited-kilometre warranty, which currently sets the standard for the premium market. It also comes with five years of roadside assistance.

The GLB35’s service intervals are long, at every 12 months or 25,000km (whichever comes first). Better yet, it’s available with a three-year/75,000km capped-price servicing plan, but it costs $2750, with the third visit alone incurring a $1300 charge.

The Santa Fe comes with a five-year/unlimited-kilometre warranty, which isn’t as good as some of its rivals, especially with Nissan now offering a 10-year warranty on its models, albeit conditional.

The pre-paid servicing plans are competitive, though, and the five-year plan averages just $481 per service.

Servicing intervals could get a bit annoying if you do a lot of kays every year as they're at every 12 months or 10,000km, whichever occurs first.

The Santa Fe petrol is a simple gal and enjoys 91RON unleaded petrol and is even E10 suitable.
