Mercedes-Benz Glb250 vs MG MG4

What's the difference?

Well, Mercedes-Benz has done it again, finding (or creating, depending on your position) a niche and filling it. But unlike some others that preceded it, this example is a good one.

Despite its safety and handling shortcomings, the GLB 250 looks the part, is undeniably practical and serves up surprising performance, which means it's a winner in our books.

The MG4 was a game changing electric car, resetting the price benchmark while also being a very good small car in its own right. But as we discovered when we tested the rest of the range, the MG4 is a car that gets more compelling the cheaper it is. The $38,990 MG4 Excite 51 is arguably the pick of the range given its value equation.

But that’s not to say the MG4 XPower isn’t a good car. It’s a very quick car that will play the role of daily driver and weekend fun machine well. Just not quite as well as its petrol-powered rivals.

These days, so many SUVs try to toe the coupe line by incorporating a sloped-back roofline –and yes, the same is predominantly true of those that call themselves traditional wagons.

That said, prepare yourself for a bit of a throwback, because the GLB 250 is about as faithful to the classic two-box design as it gets in 2020, which we absolutely love.

Up front, it's undoubtedly a Mercedes-Benz SUV, albeit with a much squarer appearance. Simply put, the GLB 250 looks butch.

We particularly love its simple LED headlights, classic grille and strong bumper, which make it look smart but capable.

Around the side, the GLB 250 is a typical small SUV with black plastic cladding covering its wheelarch extensions and connecting skirts.

The otherwise plain design is spiced up by a sporty set of alloy wheels (our test vehicle was fitted with 18-inch items with 235/55 runflat tyres) and an unusual kink in the glasshouse, around the C-pillar.

The GLB 250 is at its best at the rear, where it exudes presence, with the tough look punctuated by the droopy LED tail-lights and a prominent bumper, which houses a diffuser element flanked by dual exhaust tailpipes.

Inside, the GLB 250 quickly reveals itself to be a technological tour de force. And yes, if its cabin looks familiar, it's because its mechanical relatives (A-Class, B-Class, CLA and GLA) more or less have the same cockpit.

As expected, a pair of 10.25-inch high-resolution displays sit side by side proudly atop the dashboard, with one the central touchscreen and the other the digital instrument cluster.

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

The GLB 250 is properly premium where it counts. Sure, trainspotters will notice the black 'Artico leather' upholstery covering the steering wheel, seats, armrests and door shoulders is of the artificial variety, but it's inoffensive, unlike in some of its SUV siblings.

Soft-touch materials are used for the upper dashboard, leaving hard plastics for the lower sections, which is exactly what you'd hope for at this price.

While a black headliner lends itself to a dark cabin, brighter highlights come by way of the metallic trim used throughout, notably on the steering wheel, dashboard, doors and centre console. And let's not forget the sensational ambient lighting. It's very, very cool.

And mercifully, gloss-black accents are limited to the surrounds of the steering wheel, turbine-style front air vents, dual-zone climate controls and centre console. The less scratches and fingerprints the better, we say.

What really stands out about the design is… that not much stands out about the design. At least in differentiating the XPower from the rest of the MG4 line-up.

There are no pumped out wheel arches or a bigger, sportier spoiler that makes it look different in the same way a GR Corolla won’t be mistaken for a regular Corolla hatch.

Instead, the XPower has the same 'Energetic Agile' silhouette and includes the same ‘Active Intake spoiler’ at the front and the ‘Twin-Aero’ rear spoiler that’s the same as the Essence models.

There are some differences though, including more pronounced styling on the sides of the doors. It doesn’t add any performance benefit but creates a slight visual difference between the models in the range.

Surprisingly, there is very little to signify that this is the sportiest XPower model, with a distinct lack of badging - inside and out. In fact, the only visual clue that this is the XPower is on the bright orange brake calipers. Or, to be more accurate, brake caliper covers.

These are just lightweight metal covers that make the MG4 braking hardware look bigger than it really is, so it’s a bit of visual trickery from the MG designers.

Measuring 4638mm long (with a 2829mm wheelbase), 1834mm wide and 1659mm tall, the GLB250 is closer in size to the GLC than the GLA, making it a small SUV on paper only. And that only means good things when it comes to practicality.

For example, cargo capacity with the 50/50 split-fold third row stowed is strong, at 565L, but it can be increased to a massive 1780L with the 40/20/40 split-fold middle bench also out of action. If six or seven seats are in use, though, there's limited space to play with.

That said, the boot is still very well thought out, as evidenced by its massive aperture, lack of a load lip, and flat floor, which make loading bulkier items a lot easier. And yes, its load cover can actually be stored underfloor when not in use!

There are also four tie-down points, two bag hooks, a side storage net and a 12V power outlet to make things that little bit easier, while the rear seats can be operated from behind.

Speaking of which, let's cut straight to the point: Mercedes-Benz claims the third row can accommodate occupants that are up to 168cm tall thanks to the middle bench's ability to slide fore and aft by up to 140mm.

Therefore, my 184cm (6.0ft) frame is a little too tall, but I was still able to sit in the back, albeit not in complete comfort, with about a centimetre of legroom and negligible headroom and toe-room on offer.

The biggest challenge for any occupant is getting in and out in the first place, as the middle bench doesn't tumble forward for easy access. Needless to say, you're not going to look graceful here. Children can learn to deal with it, but adults won't be excited by the prospect.

So, the middle bench is where it's at, even when slid all the way forward. Behind my driving position, it provides about a centimetre of legroom, but this can be increased to a generous 8.0cm by sliding it all the way back.

Either way, plenty of toe-room is available alongside more than an 2.0cm of headroom – and that's with a dual-pane panoramic sunroof fitted.

The second row can accommodate three adults at a pinch, partly thanks to the short transmission tunnel that ensure there's just enough space for three pairs of fully grown feet across the two footwells. Children will be fine.

While we're on the topic, four ISOFIX and five top-tether anchorage points are on hand for fitting up to four child seats across the second and third rows, making the GLB250 a genuine option for families.

In-cabin storage options are numerous, with the central storage bin on the larger side despite housing a pair of USB-C ports, and the glove box is also pretty handy, even if it does have an odd shape. There's also a sunglasses holder in front of the rearview mirror.

The centre console's cubby doesn't lend itself to storage, though, as it's more or less taken up by two cupholders, another USB-C port and a wireless smartphone charger.

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

Second-row occupants are further treated to a fold-down armrest with another pair of cupholders, although they're of the retractable (flimsy) variety.

These passengers also have access to two USB-C ports, which fold out below a small cubby and a pair of air vents, which are located at the rear of the front centre console. There are also storage nets on the front seat backrests.

And don't make the mistake of thinking the third row misses out on the action, as two cupholders (one regular, the other small) divide the seats, which have their own USB-C ports and device straps to the sides.

As with the exterior, there’s not a lot to differentiate the XPower from the rest of the line-up. No bright red Civic Type R style interior treatment here. MG has opted to carry over the minimalist design that no doubt contributes to the sharp pricing.

Probably the only notable difference is the seat trim, with the XPower model getting a combination of synthetic leather and suede for a sportier look and feel. But the rest is largely the same, which detracts slightly from its hot hatch credentials.

On the plus side, the MG4 cabin is generally a well-designed interior space, which is a positive for the XPower’s hot hatch argument, as the idea behind the ‘hot hatch’ is that it can be a practical car during the week and fun on the weekends. 

There’s good room for passengers and luggage, in large part thanks to the relatively slim battery design that frees up more cabin space. Front seat occupants will enjoy the space and good visibility on offer.

Small item storage is very good in the MG4, with a pair of cupholders, a large, flat lidded tray (with one USB-C and one USB-A outlet just above) and the centre console box all fitting between the front seats.

There’s also a wireless smartphone charging pad that sits halfway up the centre fascia, next to the rotary gear selector, but it’s a shallow space so your phone will almost certainly fly out as soon as you begin cornering vigorously.

However, once again highlighting the ways MG has saved money to keep costs down, the back seat accommodation isn’t anywhere near as well appointed.

While the space is adequate for a small hatch, there are no cupholders, no air-conditioning vents and no fold down armrest for those in the back. All they have access to are some pockets on the back of the front seats, including a pair of small ones high on the seat, seemingly designed to accommodate your smartphone.

In another positive for its hot hatch practicality, there are ISOFIX points on the outer rear seats, neatly covered by leather pieces for a cleaner look when you don’t have kids.

As for the boot, the XPower measures the same 363 litres with the seats up which is unchanged from the rest of the MG4 line-up.

Disappointingly, there’s no obvious place to stow the charging cable, even though it comes in a small, neat bag. This is a worryingly common trend with these early generation EVs that shows a lack of practical thinking from the designers.

The MG4 has no under-bonnet storage either, so it feels like a few wasted opportunities for what is a bespoke EV design.

While we’ll dive into performance and the headline figures of the XPower soon, there’s another number that’s arguably more impressive - the price.

The MG4 XPower is priced from $59,990 (plus on-road costs), making it only $4000 more expensive than the range-topping MG4 Essence 77.

More importantly, when compared to the likes of the $72,600 Honda Civic Type R, $68,990 Volkswagen Golf R, $64,190 Toyota GR Corolla and $57,990 Subaru WRX tS Sport the XPower is arguably one of the first EVs to achieve true price parity with its internal combustion engine rivals (although the Cupra Born starts at $59,990 so it can argue the same).

Beyond the performance upgrades we’ll detail below, that price brings a well-equipped car.

The XPower comes with 18-inch alloy wheels, LED headlights and tail-lights as well as vehicle-to-load (V2L) functionality.

It also comes with a six-speaker sound system, Bluetooth, navigation, Apple CarPlay and Android Auto, a wireless smartphone charging pad and synthetic leather and Alcantara trim. 

There’s the 'MG Pilot' safety package included as standard as well, but we’ll detail that below.

The 'Hunter Green' hero paint colour is exclusive to the XPower in the MG4 range, and is reportedly inspired by an MG land speed record car the legendary Sir Stirling Moss drove in the 1950s.

The GLB 250 is motivated by a peppy 2.0-litre turbo-petrol four-cylinder engine that produces 165kW of power from 5500-6100rpm and 350Nm of torque from 1800-4000rpm.

This unit is mated to an eight-speed dual-clutch automatic transmission that's solid on debut, while Mercedes-Benz's 4Matic all-wheel-drive system is also in tow.

Thanks to this combination, the GLB250 can sprint from a standstill to 100km/h in a brisk 6.9 seconds while on the way to its top speed of 236km/h. It also enables a maximum braked towing capacity of 2000kg.

This is arguably the biggest single difference between the XPower and the rest of the MG4 line-up. Unlike the others that have a single, rear-mounted electric motor, the XPower adds a second motor on the front axle.

This has an obvious impact on the performance, boosting it from the previous best of 180kW to an impressive 320kW/600Nm.

Having motors on each axle also means the XPower is all-wheel drive, so it has little trouble transferring all that grunt to the road.

So much so that the MG4 XPower is the equal quickest hot hatch on the market (at the time of publication), taking just 3.8 seconds to run 0-100km/h; matching the Audi RS3, with its turbocharged five-cylinder engine.

The GLB250's fuel consumption on the combined-cycle test (ADR 81/02) is 7.7 litres per 100 kilometres, while its carbon dioxide emissions are 173 grams per kilometre. Both claims are pretty solid.

In our real-world testing, though, we averaged 8.9L/100km over 180km of driving skewed towards country roads over highways. As such, it's a strong result, especially when you consider my lead foot.

For reference, the GLB 250's 60L fuel tank takes 95RON petrol at minimum.

Interestingly, the XPower is not fitted with the biggest battery in the MG4 range, forgoing the 77kWh version in favour of the 64kWh option.

In the ‘standard’ rear-wheel drive MG4 Excite 64 model this battery can provide up to 450km of range (on the WLTP cycle) but in the XPower that figure is reduced to 400km.

While that’s well short of the 530km offered by the long-range Essence 77 model, it’s still a respectable amount of driving range and should suit your typical hot hatch buyer, who knows performance typically comes at the expense of efficiency.

Our test drive was limited to just two days, so we didn't have the chance to live with the XPower for an extended period, but it managed to make it this reviewer’s preferred hot hatch playground on the edge of the city and back again to home with more than 50 per cent of the battery charge remaining.

This was a trip that included a lot of urban driving, some highway and then some ‘spirited’ running on the twisty road, so there’s enough range from the XPower to meet most buyers' needs.

Across almost seven hours of driving, the MG’s trip computer was claiming an average energy use of 18.6kWh/100km. To replenish the batteries, a 140kW DC charger will take just 30 minutes to take them from 10 to 80 per cent.

The V2L is another nice addition, which allows you to draw power from the battery, if needed, to run small electrical appliances.

The XPower is hardly a car for camping but, for example, if you decided to take it to a track day and want to plug in a kettle to make a hot drink, you can literally plug it into the car. Handy!

Families are sure to be pleased by the way the GLB 250 drives, because it can be summed up in one word - comfortable.

A lot of the credit has to go to the GLB 250's independent suspension set-up, which consists of MacPherson-strut front and trailing-link rear axles with adaptive dampers.

The ride is sensational, with the GLB just wafting along on the highway. Take it onto a coarse-chip road and this quality does suffer, but not much. That said, road noise does become more of a factor on lower-quality tarmac.

It's worth reiterating that our test vehicle was fitted with 18-inch alloy wheels, which are an inch smaller than the GLB 250's standard set that come with lower-profile tyres (235/50), so the chances are our glowing review doesn't apply across the board.

There were also some noticeable underbody creaks when navigating speed bumps and the like, but hopefully they're just specific to our test vehicle.

What will be more consistent, though, is the wind noise generated by the side mirrors at highway speeds. It penetrates the cabin and disturbs its serenity more than any underbody creak ever could, so turn up the sound system.

Handling-wise, the GLB 250 performs just as well as any other non-performance SUV with seven seats and a high centre of gravity, with body roll prominent when cornering with intent.

Put the aforementioned adaptive dampers into their sportiest setting and body control improves somewhat, but you'll still be conscious of the GLB 250's 1721kg kerb weight.

Either way, grip is quite good due to the all-wheel drive system, which works hard to keep things on track. Its front bias is apparent, though, with the GLB 250 running wide of its line at times.

While it's not the sharpest handler, the GLB 250 is far from awful, partly thanks to the electric power steering's variable ratio set-up.

This system goes from lock-to-lock with ease at low speed, making parking manoeuvres much easier to perform, while it's far more stable at high speed.

However, it's not the first word in feel despite being well-weighted… until you make the mistake of engaging the GLB 250's Sport drive mode, which adds too much artificial weight.

Speaking of sporty, the GLB 250 is surprisingly fun in a straight line thanks to its strong engine and transmission combination.

I particularly enjoyed the 2.0-litre turbo-petrol four-cylinder engine's mid-range, headlined by a useful 350Nm of max torque from 1800-4000rpm.

Once it comes and goes, though, it's a 'long' wait until 165kW of peak power kicks in from 5500-6100rpm, so best to up-shift early.

Doing so is very easy due to the new eight-speed dual-clutch automatic transmission, which serves up gear changes that are only smooth, but quick.

Engage Sport drive mode and the engine and transmission become that little bit sharper, with the former's throttle response improved, while the latter adopts more aggressive shift patterns.

That said, it's best to resist that temptation, as the GLB 250 is at its best when driven calmly, while it exudes family-friendly comfort.

The real question about the XPower is not if it’s quick, because all EVs and especially those with dual motors tend to be very rapid in a straight line, but how it handles itself on a twisty road.

That’s what separates a good hot hatch from a great one, but it’s also an area EVs have struggled in, because the combination of silence, weight and just the fact they’re new and different tends to mean they lack the driving engagement of more established competition.

Hot hatches also need to play a dual role, as daily transport and weekend fun machine, so that’s another factor to consider.

So, how does the MG4 XPower stack up? Well, the unsurprising news is it’s very, very quick. The acceleration is ferocious and really shoves you back in your seat, leaving you in no doubt that it will leave most of its hot hatch rivals (with the exception of the Audi RS3) in its dust.

When the going gets twisty though the XPower feels like it lets its rivals catch back up. There are different driving modes and switching to ‘Sport’ and reducing the regenerative braking makes a notable difference to the way the XPower handles.

The steering gets heavier and it will roll and coast into corners more like a petrol-powered hatch. It makes for a very competent car, with direct steering and good road holding… but not a great hot hatch.

It lacks the engagement and excitement that the best hot hatches offer. For example, the steering gets heavier in Sport mode, but doesn’t provide any more feedback to the driver. The Bridgestone Turanza tyres do a fine job but they lack the grip of a Michelin Pilot Sport. 

The lasting impression on the driver is a car that feels quick but doesn’t leave you wanting more. The best hot hatches make you want to keep on driving and driving, that’s not the case in the XPower.

As a daily driver it’s arguably better than its rivals, though, with quiet, effortless commuting potential thanks to its electric powertrain.

There’s the usual passive safety features, including six airbags as well as the required stability controls, anti-lock brakes and the like, however the XPower also comes equipped with the MG Pilot suite of active safety features as standard.

MG Pilot includes autonomous emergency braking, lane keeping assist, lane departure warning, adaptive cruise control, blind-spot monitoring and rear cross-traffic alert.

Thanks to all of this safety gear, the MG4 range was awarded a maximum five-star ANCAP assessment, when it was tested in 2022.

As with all Mercedes-Benz models, the GLB 250 comes with a five-year/unlimited-kilometre warranty, which is the gold standard for the premium market. It also comes with five years of roadside assistance.

The GLB 250's service intervals are every 12 months or 25,000km, whichever comes first. It is available with a three-year capped-price servicing plan for $2650, but its pricing can be reduced by $500 if paid upfront alongside the vehicle.

Like every MG sold in Australia, the MG4 XPower is covered by the brand’s seven-year, unlimited kilometre warranty, which is industry standard for high-volume brands these days.

As for servicing, the intervals are also the same as the rest of the MG4 range, which means a lengthy two years or 40,000km, whichever comes first, between visits to the dealership.

That’s much longer than your typical petrol-powered hot hatch, which has more moving parts that need servicing. 

In terms of costs, the XPower is ever-so-slightly more expensive compared to the rest of the MG4 line-up.

A minor service is the same $296 but a major service (which comes every second service) will cost you $962.

But even so, for the first six years you’ll only be up for $1554 in servicing costs, which is comparatively cheap amongst its hot hatch rivals, and only $76 more than you’ll pay for any other MG4.
