BMW 550I vs Mercedes-Benz GLB

What's the difference?

Not all superheroes wear capes, and we're proud to report the 530e does its bit for green motoring without feeling the need to shout about it. And with no price or specification penalty, it's easier being green than ever before, and the pricing of this BMW really puts the cat amongst the canaries.

The Mercedes-Benz GLB is an oddball. While it isn’t my definition of beauty, it's a surprisingly capable and spacious small-to-medium SUV.

The entry-level GLB200, while comfortable, feels a bit underdone in the engine department. Therefore the mid-spec GLB250 with the more-powerful 2.0-litre turbo and mild-hybrid assistance plus all-wheel drive grip is the better pick.

Crucially, there's nothing weird about the way the 530e looks. While some green cars look like they've been designed by one of the kids from 3rd Rock from the Sun, the 530e looks much the same as the rest of the range, save a few tiny but telltale giveaways - like the e-drive badging outside, and what looks like a bonus fuel flap tucked in behind a front wheel that houses the whole plug-in bit.

And we really, really like it. It's elegant and statesman-like from every angle, and looked especially important in the deep-blue colour of our test vehicle. It's not over-designed, with body creases used sparingly, and the occasional glint of polished silver that rings the windows and the grille adds a final sense of shininess to an understated design. 

Inside, there's more going on than you might normally find in a BMW. The hugely complicated digital display screen now includes everything from battery charge, power usage to the usual assortment of speedometers and petrol readouts. 

It doesn't feel overdone or crazily festooned, but there's more at play here than in your usual BMW.

The dash is busy, too, with a wide screen emerging from a centre stack that also houses a CD player and a digital aircon setup, which in turn sits above a complex centre console from which you can alter driving settings, control the multimedia or cycle through electric modes. It doesn't feel overdone or crazily festooned, but there's more at play here than in your usual BMW.

Elsewhere inside, the seats are beautifully designed, with a quilted leather highlight through the middle, while the gloss-black strip that lines the dash hides a dual strip of ambient interior lights that also runs across all four doors.

This isn’t the prettiest car ever. It has the Mazda CX-8 or CX-80 effect where you can tell a smaller car has been stretched and extended to create more interior space. It just looks a little awkward as a result.

The rear section of the GLB in particular is much higher and boxier than the GLA which makes it look rather back-heavy. Thankfully roof rails are standard which toughens the look somewhat.

The facelift that was introduced in 2023 brought an updated front bumper, as well as tweaked LED headlight and tail-light signatures. The changes aren’t wildly different from the original car that launched in 2019 but it’s still fresh enough.

Inside is where this car is starting to look its age. While Mercedes-Benz was one of the first to introduce a wraparound screen set-up combining the digital instrument cluster and touchscreen multimedia system into a single unit, many have copied this and it no longer looks unique.

It doesn’t help that the dual 10.25-inch screens are small now in comparison to newer rivals. It’s standard for a digital instrument cluster to be closer to 12.3-inches in diameter now.

A main interior change with this facelift included the removal of the touchpad controller on the centre console. In its place is now a shallow storage area which doesn’t really serve a purpose.

There’s also a new AMG-style steering wheel as standard which has fiddly gloss black touch sliders that get grimy upon use.

While the changes are welcome, the ageing roots are still present. You can’t escape the blingy touches that just end up looking cheap and tacky.

A key example of this are the air vents which have obnoxious interior ambient lighting in them to try and make the cabin look cool.

I’m also not a huge fan of the star pattern trim on the dashboard and the swathes of stainless steel-looking inlays.

As the world's motoring tastes shrink faster than a lap-banded Clive Palmer, it's easy to forget the joys of the full-size sedan, but the space for passengers and luggage in the 5 Series will have you questioning your downsizing ways.

Upfront, there's plenty of room between front-seat riders, who will also share two smallish cup holders, along with room in each front door for bottles. There's also a dedicated wireless charge pad (which, because of its tight design, is crazy difficult to actually remove your phone from), but you'll also get two USB points and a power outlet that's hidden in the sizeable centre storage bin as standard fit.

Backseat riders get heaps of space, both in width and in leg room behind the front seats. And there's twin air-con temp controls and twin power outlets, too. But middle-seat passengers will be forced to sit with their legs on either side of the raised tunnel, which will definitely impact on comfort.

The boot's still sizeable, despite shrinking slightly to house the battery/fuel tank setup

Best to ditch the fifth passenger, then, and deploy the pull-down seat divider, which also houses two cup holders. Finally, there are three ISOFIX attachment points, one for each seat in the back.

The boot's still sizeable, despite shrinking slightly to house the battery/fuel tank setup (the tank has been moved further back to accomodate the batteries), and can be adjusted to be a flat load area if you'd like, offering up to 410 litres with the rear seats in place.

Up front the driver’s seat is comfortable, offering electric adjustability and lumbar support, extendable thigh support and heating. Some extra bolstering on the seat base would be nice though as it’s a little flat for my liking.

While the glossy piano black touch sliders on the steering wheel aren’t the most intuitive, I love holding this leather-wrapped wheel as it straddles the line of being thick enough but not too thick. BMW should take note…

The thin stalks behind the steering wheel are a joy to use and have a nice thwack to them. I appreciate the column-mounted gear selector as this frees up more space on the centre console, though it could be utilised better. More on this in a bit.

The digital instrument cluster offers a range of different themes to select from, though the standard version looks the nicest and offers the most customisation. It’s nice being able to put a full-width map display on the instrument cluster.

The touchscreen multimedia system offers a clean and intuitive interface that’s hard to get lost in. For the most part, however, I ended up using smartphone mirroring. Thankfully this update brought wireless Apple CarPlay and Android Auto.

It’s nice having the row of physical climate control switchgear within easy reach especially as carmakers are now integrating these into the touchscreen interface. Even Mercedes-Benz is guilty of this in its newer cars.

There isn’t a tonne of general storage on the centre console beyond the deep central box which has a split-opening lid. The wireless charger barely fits my iPhone 15 Pro Max, the cupholders are on the small side and the aforementioned storage section where the touch slider once was is useless from a storage standpoint.

Moving to the second row, it’s rather spacious for a small-ish SUV. At a leggy 182cm tall, I have plenty of leg and headroom behind my own driving position.

You’re able to slide and recline each individual seat in the second row to prioritise second-row comfort or allow more space for third-row passengers. It’s needed because third-row space is tight!

Second-row amenities include air vents mounted on the back of the centre console, various storage spaces, two USB-C ports, as well as a fold-down armrest with cupholders. Also if you stare at the back of the centre console it looks very much like a screaming face.

As already mentioned, the third row isn’t the most spacious ever, although this is a small-ish SUV so best not to expect palatial levels of room. It’s likely more for occasional use by children and it’s good to note there is airbag coverage back there.

Amenities are few and far between in the third row, limited to just a few storage spots and a USB-C port on both sides. Unfortunately there are no air vents.

At the back there’s a handsfree power tailgate which is handy if you’ve got your hands full. It opens swiftly, though with all three rows of seating upright there isn’t much room at all. Mercedes-Benz doesn’t even quote a boot capacity figure, but it’s only enough for a bag or two.

Thankfully if you’re not using the third row the benefit of this car is there’s much more boot space than the GLA. Mercedes-Benz claims there’s a generous 565L of boot space, which can further expand to 1800L with the second row folded.

Unfortunately there is no spare wheel in the GLB200 as it has run-flat tyres as standard, though regular tyres with a tyre repair kit is a no-cost option.

The Mercedes-Benz GLB200 is currently priced at $67,600 before on-road costs.

There aren’t many premium seven-seat SUVs that are this compact out there. The closest rivals would be the mid-size Volkswagen Tayron and related Skoda Kodiaq.

But for this price you can easily get something larger like a Kia Sorento, Hyundai Santa Fe or Mazda CX-80. You do have to ditch the premo badge though.

For your money you do get a generous amount of standard equipment. This includes 19-inch alloy wheels, LED headlights, dual 10.25-inch screens, wireless Apple CarPlay and Android Auto, interior ambient lighting, as well as heated front seats with electric adjustment.

However our tester was optioned with a panoramic glass sunroof ($1900) and black leather upholstery ($1539), bringing the as-tested price to $71,039 before on-road costs. This is still around $18,000 off the cheapest GLC.

A nifty reason for opting for this car over the GLA is because there’s a third row of seating. It's not the most spacious row, but when folded there is more boot space. More on this later.

Drift around in pure EV mode and you'll be relying on the 530e's 83kW and 250Nm electric motor, which will provide what BMW refers to as "between 28 and 32 real-world kilometres".

Run out of range, or simply use too much throttle, and the 2.0-litre petrol engine comes into play, adding 135kW and 320Nm to the mix. All up, that's 185kW and 420Nm - respectable numbers by any measure, and enough to match the petrol-powered 530i's zero to 100km/h sprint of 6.2 seconds.

That power is fed through an eight-speed automatic transmission before being sent exclusively to the rear wheels, where it belongs.

The Mercedes-Benz GLB200 is powered by a 1.3-litre turbocharged four-cylinder petrol engine which produces 120kW and 270Nm.

This engine also features in ‘200’ versions of the A-Class, CLA and GLA, plus versions of it also feature in the Renault Arkana, Captur, Duster, and Kangoo, as well as the Nissan Qashqai and now the new Mitsubishi ASX.

It’s mated to a seven-speed dual-clutch automatic transmission with drive sent to the front wheels only.

Unlike the more powerful GLB250 and AMG GLB35 all-wheel drive trims, the GLB200 is the only model to go without 48V mild-hybrid assistance in Australia. It was originally promised when this facelifted model was announced in 2023.

Mercedes-Benz claims the GLB200 can do the 0-100km/h sprint in 9.3 seconds and top speed is 207km/h.

Like a Facebook relationship status, it's complicated. The 530e will sip a claimed combined 2.3 litres per hundred kilometres on the claimed/combined cycle, which is amazing for a car this size. Better still, it seems genuinely achievable - at the vehicle's launch, our own Richard Berry recorded a stunning 2.0 litres per hundred kilometres on a short test route.

But that's with a full load of battery charge on board. For our week with the 530e we were unable to actually plug it in (living in Sydney, I can't afford a garage), so once the initial battery charge had been used we were back to mostly petrol power. Unlike some other plug-in hybrids we've driven, we found it very difficult to recharge the battery to any meaningful level using regenerative braking, so once we were flat we stayed flat. If we had plugged it in, it would have been a two-hour recharge using a specialised wall unit, or about four hours using a normal plug.

As a result, though, our fuel use was closer to 7.0 litres per hundred kilometres after some considerable real-world testing.

Mercedes-Benz claims the GLB200 has a combined fuel consumption of 7.5L/100km.

During our urban and metropolitan-based testing, however, we saw an average of 9.0L/100km according to the trip computer which isn’t great but also not the worst I’ve seen. Expect this figure to balloon out further if you load more people onboard as the engine will have to work harder.

There is a 52L fuel tank which requires a minimum of 95 RON premium unleaded petrol.

Using my as-tested fuel consumption figure, this means the GLB200 has a theoretical range of up to 578km.

There's so much to like about the way the 530e sets about saving the world, and that's mostly because it doesn't shout about it, either to the driver or the outside world.

It's very much an underpants inside its pants superhero, which makes us like it even more. Set off in EV mode, and the 530e will drift silently away from the curb, burning battery power over fuel for as many as 30(ish) kilometres. But equally important, the shift from green to gas is largely imperceptible, with the petrol engine joining in willingly when you ask it to - usual via a prod of your right foot.

It is so effortlessly smooth that you need to really pay attention to notice the eight-speed 'box changing gears at city speeds, and it's commendably quiet, whichever drive mode you're in.

Downsides? Well, it doesn't feel quite as sharp as it's conventional-engined siblings. The batteries add around 230kg in weight, which never helps, and it all feels a little softer and a little less dynamic, even with Sport mode engaged. BMW assures us the adaptive suspension setup and tune is identical, but the 530e feels noticeably softer when you tackle a twisting back road. And that encourages you to use your right foot a little more, which in turn negates the whole electric thing in the first place.

One of the great joys of BMWs has always been their ability to transform from cosseting comfort to rear-drive rocket when you want them to, and you can't help but notice the 530e isn't quite up to that challenge. But if your intentions are mostly city- and freeway-based, then this plug-in BMW is almost indiscernible from its petrol-powered sibling.

While this 1.3-litre turbo engine may be sufficient in the smaller A-Class and GLA, it barely scrapes by in the GLB200.

Even with one person onboard the engine has to rev out the first few gears to around 3000rpm to keep up with traffic from the lights. It doesn't have the nicest engine note either.

It doesn’t help that the dual-clutch automatic can be a little vague from a standstill, taking a beat to kick into action. This is most noticeable when doing low-speed manoeuvres or reversing.

Although initial acceleration can be on the thrashy side, rolling acceleration while at speed is a lot more linear and calm thanks to peak torque coming on tap from 2000rpm. This means the car will only downshift when it needs to.

There are a few different drive modes you can select from, but the default ‘Comfort’ mode feels the most natural. ‘Eco’ does quell some of the rev flares during initial acceleration, though the engine feels much more tardy in general.

Linked with these drive modes are the adaptive dampers. This is a very comfortable car, especially on the standard smaller 19-inch alloy wheels as there’s plenty of tyre sidewall to absorb bigger bumps.

Coupled with this is sporty steering that’s direct and makes the car feel nimble despite its 1.7-tonne kerb weight.

It really is the best of both worlds because you get the fun and sporty characteristics from the steering, plus the comfort and supple feeling from the suspension. It’s hard to fault this set-up.

In terms of noise, vibration and harshness (NVH), if you look beyond the sometimes shouty engine, this car is quiet and refined. There’s some tyre roar at higher speeds, but many European vehicles have this trait.

It’s also a benefit that this car is a little older as there aren’t many safety system-related bings and bongs that distract from the cabin ambience.

The Mercedes-Benz GLB received a five-star ANCAP safety rating based on Euro NCAP testing conducted in 2019.

It received 92 per cent in Adult Occupant Protection, 88 per cent in Child Occupant Protection, 78 per cent in Vulnerable Road User Protection and 76 per cent in Safety Assist.

As standard there are nine airbags, autonomous emergency braking (AEB), blind-spot monitoring, rear cross-traffic alert, lane-keep assist, adaptive cruise control, front and rear parking sensors, as well as a surround-view camera.

A nifty safety feature is the Pre-Safe system which tightens the seatbelts and plays a tone when it detects an imminent crash.

There are ISOFIX child seat anchor points on the outboard second-row seats, as well as on the two third-row seats. All three second-row seats, plus the two third-row seats also have top-tether points.

Like the rest of the 5 Series range, the 530e falls under BMW's three-year, unlimited-kilometre warranty. There are no set service intervals, either, with BMW using what it calls 'condition-based' servicing. In other words, the car will tell you when it requires a trip to the service centre.

The batteries are covered by a separate warranty covering six years or 100,000km.

The GLB200 is covered by a five-year, unlimited-kilometre warranty, like the rest of the Mercedes-Benz line-up.

Logbook servicing is every 12 months or 25,000km, whichever comes first, which is good if you do a lot of driving.

You can purchase a three-, four- or five-year service package which costs $3495, $4650 and $6185, respectively. With the latter this equals $1237 per service, which is expensive, although it is cheaper than the slightly larger GLC.
