Mercedes-Benz GLB-Class vs MG Mg4 Urban

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.

The MG4 Urban is not only the right car at the right time, perfectly catering to buyers looking to avoid rising petrol prices, it’s also a welcome return-to-form for MG as a brand.

MG is seemingly at its best when it sticks to small cars. It has traditionally excelled with the MG3 and ZS, smaller, more affordable products that keep expectations in check and can win over customers looking for the best bang-for-their-buck rather than simply the best car.

That’s not to say the MG4 Urban isn’t a good car. It offers tremendous value for money, excellent interior space and drives nicely, so anyone who has been considering making the switch to an EV should seriously consider this new arrival.

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.

MG says the design inspiration for the MG4 Urban came from the $100,000 Cyberster. While there are certainly a lot of differences between that roadster and this hatchback, the air-intakes and wheel design are indeed very similar. And I guess the badge is the same too, so there’s that…

But, comparing it to the Cyberster misses the point. What makes the MG4 Urban’s design more interesting is the bits you can’t see. While it shares the same name as the MG4 Hatch, this car has almost nothing in common with it. That’s because this new MG4 Urban is based on the brand’s newer EV underpinnings that debuted on the MGS5 EV.

That means the MG4 Urban is front-wheel drive, whereas the hatch is rear-wheel drive, and because of the way the battery is integrated into the chassis, it creates not only a bigger hatchback but also one with a different shape.

The Urban is more ‘cab forward’ (to use design parlance) meaning a shorter bonnet, which creates more cabin room. It also means there is more boot space because the powertrain is located up front.

MG does a good job with cabin presentation too. It’s another step forward for the brand, improving the overall level of fit and finish from its earlier models, to create a cabin that looks modern and doesn’t feel like it has been built to a price.

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.
 

As I just mentioned, the cabin is bigger than the other MG4, which creates good space in both seating rows. 

Up front they’ve placed the gear selector on the steering column to create space for more storage in the centre of the car. That means there’s plenty of shelves, cubbies and cup holders to take care of your small (and not so small) items, spread across the cabin.

As for the boot, the switch to a front motor and a smaller rear suspension means a 382-litre boot with all seats up and 1266L if you drop the back seats. Plus there’s a 98L underfloor storage spot, in place of a spare wheel (with a puncture repair kit included instead).

The design of the key controls are simple and easy to use, with a digital display for the instruments ahead of the driver and a 12.8-inch multimedia screen in the centre of the dashboard.

Navigating the menus is relatively straightforward but in a victory for user-friendliness, MG has listened to feedback (and incoming Chinese government regulations) and added some physical controls. There are buttons and a dial for the air-conditioning system and a volume knob for the sound system.

MG made its reputation in Australia by selling some of the most-affordable models on the market, filling the hole left by mainstream brands like Toyota, Hyundai and Mazda as they increased the entry-level prices in their respective line-ups. Something MG itself tried with the HS, QS and U9, as it expanded beyond the once-popular MG3, MG5 and ZS.

The MG4 Urban is a return to form in that sense for MG, with this new small car starting at just $31,990 drive-away. For context, the MG4 Hatch starts at $37,990 drive-away, so this is a much cheaper proposition. That starting price is for the MG4 Urban Standard Range, the Extended Range variant is priced from $34,990 drive-away.

That pricing does not feel accidental from MG Australia, despite what they may suggest when pressed. That’s because the new BYD Atto 2, the direct rival to the Urban, starts at $31,990 plus on-road costs. Even so, BYD has the last laugh, because it offers both the BYD Atto 1, which starts at $23,990, and the Dolphin, which is priced from $29,990 - to undercut the MG4 Urban, even if neither are considered direct competitors.

In terms of specification, both the Standard Range and Extended Range have the same equipment with the exception of the obvious - a bigger battery, and more power from the motor.

Standard equipment highlights include 17-inch alloy wheels, LED headlights and tail-lights, a leather-wrapped steering wheel, PVC seat upholstery, heated front seats, Bluetooth connectivity with wireless Apple CarPlay and Android Auto, in-built navigation and a six-speaker stereo.

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 MG4 Urban Standard Range is powered by a 110kW/250Nm electric motor that drives the front-wheels via a single-speed transmission. The Extended Range has slightly more performance, 118kW and 250Nm, but aside from that they are the same motor.

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 biggest difference between the two MG4 Urban variants is the battery. The Standard Range has a 43kWh battery good for 316km of driving between charging, while the Extended Range gets a bigger 54kWh battery to make it capable of up to 405km.

We didn’t drive the car long enough to get a clear indication of real-world efficiency and range, but it performed well during our drive in suburban Sydney. The steady stop-start traffic gave the battery its best chance to perform well and the early indications are its range is close to claim, at least under the right circumstances. We’ll have to reserve definitive judgement until we’ve had a longer test drive.

What MG was very keen to highlight are the cost savings of buying an EV at a time of sky-high petrol prices. The company made a point that using off-peak electricity, which can be had for just 6c per kW from certain providers, means you can replenish the battery of the MG4 Urban Standard for just $3.44. 

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.

What really stood out about the MG4 Hatch is its rear-motor, rear-wheel-drive layout, which made it a very dynamic and almost sporty car. In my 2023 review I called it “a genuinely enjoyable small car to drive".

The MG4 Urban doesn’t quite leave the same impression. Again, we had only a brief and (appropriately) urban test drive around Sydney’s beachside suburbs, but the MG4 Urban proved competent rather than commendable.

But, let’s be honest, unless you’re looking for driving thrills in the wrong place (affordable, city-focused hatchbacks) the MG4 Urban does the job it is required to do. It’s as nice as any other mainstream hatch to drive from Point A to Point B.

The ride could be a little softer and more compliant, with the suspension feeling too firm at times, but with its electric motor it’s a quiet and relaxed driving experience. The electric motor provides adequate performance too, certainly more torque in less time than you’ll get in a petrol-powered hatch.

Curiously, MG Australia executives said the MG4 Urban was locally evaluated and tuned but could only offer a vague mention of ‘holistic’ changes to better suit it to local conditions, rather than pointing to any specific Australia-developed changes to the suspension, steering or powertrain.

It may be small and cheap, but that doesn’t mean MG has cut corners on safety. The MG4 Urban comes equipped with the MG Pilot and a suite of active safety features, including adaptive cruise control, autonomous emergency braking, lane keep assist, blind spot monitoring, driver attention monitoring and speed limit notification.

The latter two are the most evident, as they provide a steady soundtrack of beeps as you drive along. Take your eyes off the road for more than a few seconds as the driver attention system fires up, while the speed sign recognition gets busy in Australia’s ever-changing speed limits.

While MG has undoubtedly improved the sensitivity of some of these systems compared to other models, they are still more active than rival products. Perhaps more concerning, the speed limit recognition repeatedly beeped to tell me I was in a ‘25km/h’ zone, which is simply not a recognised speed limit on Sydney roads.

Like so many other brands, MG needs to further refine these active safety systems in order to make the driving experience more relaxed and less distracting.

MG says the MG4 Urban has secured a five-star rating from Euro NCAP, which is expected to be carried over by ANCAP. 

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 MG4 Urban is covered by the brand’s 10-year/250,000km warranty, as long as you service it at an official MG service centre. If you don’t get your car serviced with the company directly, your warranty reverts to seven-year/unlimited km coverage.

Servicing intervals are every 12 months or 25,000km and will cost you $1366 over the first five years. The cheapest visit is just $149 but the major service, after four years, is a pricey $472, which does push against the idea that EVs are cheaper to service due to less moving parts.
