Mercedes-Benz GLB-Class vs BMW X1

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.

This new BMW X1 feels like it's been built by a team of parents because it’s one of the most practical and easy to use small SUVs my family and I have ever lived with and, trust me, they’ve seen a lot of test cars come through the Berry garage.

We loved the roomy interior with high ceilings, the clever storage everywhere from the giant door pockets to the floating centre armrest up front and big boot for our pram.

Entry and exit is easy through the tall and wide doors, something my back was thankful for every time I had to put our baby into her car seat.

Driving is easy, with great visibility and the engine that comes in the xDrive20i M Sport makes this X1 sporty and fun to pilot, too.  

The only drawback is the price, it's a bit expensive but at the same time you are getting a high-quality feeling SUV.

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.

This current generation of X1 arrived in late 2022 and finally looked more like part of the BMW SUV family with tall and boxy styling rather than the sleek, but raised hatchback it seemed to be before.

My test car had 'M Portimao Blue' metallic paint - a flattering hue that showed off the X1’s lines as you can see in the images.

I like the X1’s oversized grille which suits the angry looking front bumper that comes with the M Sport inclusions, but balanced by pretty headlights.

Inside, the X1 xDrive20i M Sport is modern and minimalist in design. I like the floating centre armrest in between the driver and front passenger and the way it creates a feeling of more space and adds more storage.

The double screens are nice, but we’re seeing this same design and tech now in budget cars such as the Chery Omoda 5 and Haval H6. BMW needs to be even slicker and more stylish if it wants to maintain its edge.  

If you like your SUVs sporty looking then check out the BMW X2, X4 and X6. These are coupe style SUVs (but with four doors).

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.
 

My family found the X1 xDrive20i to be one of the most practical small SUVs we’ve lived with thanks to its spacious interior, clever cabin storage and plenty of convenient features.

I need to point out the door pockets - they’re the biggest I’ve ever seen. They’re more door buckets than pockets and super helpful over the week not just for bottles but for everything else that I needed to dump out of my own pockets and into them.

The floating centre armrest up front looks like an ironing board and has a tonne of storage underneath.

The wireless charging is handy but the holster is a bit un-user friendly in terms of access, but it held the phone tight and stopped it becoming a projectile when driving, which is what you want.

There are power outlets galore, too, proximity unlocking, and a gesture tailgate.

Legroom in the back is excellent and there’s so much headroom throughout. 

The X1’s 540-litre boot capacity is excellent for the class and meant we could fit our baby’s big pram and the seven-year old’s scooter and still have room for the grocery shopping.

In the space of driving this SUV and writing this review the list price of the X1 xDrive20i M Sport has risen from $68,900 to $73,400. 

That price hike was part of an increase across the model range and all grades now cost more, even the entry-level sDrive18i which is now 13K less than the xDrive20i M Sport.

But you’re paying for the more powerful, athletic and only all-wheel drive one in the X1 range. 

You’re also getting loads of standard features in the xDrive20i M Sport. 

There’s the 10.25-inch instrument display with three different styles for your speedo and other gauges, while flowing into that is the 10.7-inch media screen with sat nav, wireless Apple CarPlay and Android Auto, and digital radio. 

There are LED headlights, plus proximity unlocking, a head-up display, dual-zone climate control, a power tailgate, sports seats (the front ones are heated and power adjustable) and adaptive cruise control.

As the name suggests the xDrive20i M Sport is fitted with BMW M Sport goodies as standard. These include adaptive M Suspension, M leather steering wheel, M roof rails, M headliner and M interior trim. 

My test car also had $8900 worth of options fitted including the sunroof, Harman Kardon stereo, the ‘Vernasca Black’ leather seats and 20-inch M light alloy multi-spoke wheels.

Is it good value? Well, you do get a lot of nice things here but at a $13,000 premium over the entry grade, plus the $3500 price jump in the past few weeks, I’d say the value isn’t great.

If you’re trying to keep the cost down, the sDrive18i is the budget pick. 

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.

The X1 xDrive20i M Sport has a more powerful engine than the grades below it in the range - it’s a 2.0-litre, turbo-petrol, four-cylinder making 150kW and 300Nm.

A seven-speed dual-clutch automatic transmission does the shifting for you.   

This is also the only all-wheel drive X1 currently in the range.

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.

BMW says that after a combination of open and urban roads the X1 xDrive20i M Sport will use 7.4L/100km.

In my own testing my driving was mainly city and suburban, which uses quite a lot of fuel. We did dashes to birthday parties, the grocery shopping, school drop offs and all of it in busy traffic.  

I recorded 8.9L/100km, but that’s not overly thirsty considering I was carrying two car seats with children, and all the gear that goes with them. 

A small 45 litre tank means the xDrive 20i M Sport has a range of about 608km, which is on the shorter side.

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.

Only a week before testing the X1 xDrive20i M Sport I’d been reviewing a BMW 330e and going from the 3 Series to the SUV was like changing my seating position from being in a bathtub to sitting on a bar stool. 

Actually, the X1’s seat is far more comfortable than a stool and the refined quality is what you’d expect from BMW.

But compared to the low slung 330e the visibility and the upright driving angle of the X1 is very different.

It’s something you want in an SUV that puts practicality before performance.

As much as I liked the sporty sedan, as a dad I preferred being able to see better when parking in the X1, and this made life a lot easier.

Easy is a good word to describe what the X1 xDrive20i M Sport is like to drive - from that visibility to the light steering, comfortable ride and that great engine with all-wheel drive.

That 2.0-litre four-cylinder has more than enough grunt to run up the steep hills in my neighbourhood without struggling, the transmission is smooth and the all-wheel drive system adds a bit more reassurance in the wet weather.

All of this makes for an easy, enjoyable drive. 

The X1xDrive20i M Sport like all X1s scored the maximum five-star ANCAP rating in 2022.

A score of 88 per cent was given to child protection and the ANCAP report found that a 10-year old and six-year old in the second row had adequate to good protection in a front offset collision and a side impact. 

For child seats there are two ISOFIX points and three top tether anchor mounts across the second row.

As you would expect from a model that’s hasn’t even been around a year yet, the X1 xDrive20i M Sport has the very latest in advanced safety tech.

There’s AEB which is operational from 5.0km/h to 210km/h and also works at road junctions. There’s lane keeping assistance, blind-spot warning and rear cross-traffic alert. 

There are curtain airbags for front and rear passengers, a centre airbag for the driver and co-pilot along with frontal airbags plus side chest and side pelvis airbags.

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 X1 xDrive20i M Sport is covered by BMW’s five-year/unlimited kilometre warranty.

A five-year/80,000km service plan through BMW will cost $2150. You’ll be looking to pay an average of $430 per service every 12 months.
