MG Mg4 Urban vs Mercedes-AMG GLC63

What's the difference?

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.

Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.

Obviously, I had nothing to worry about. The GLC 63 S is the same boisterous, silly car I drove 18 months ago, just with a few new bits to improve the package. As ever, the GLC 63 S is all about the experience - big noise, huge grip but all in comfort with plenty of gadgets.

The only real issues are price, service pricing and the length of the warranty. The first two probably won't bother most owners and one hopes the third won't be problem, but it would be nice if the length was reflected in the price.

If you care about badge, it has impeccable credentials, the AMG stripes and that plate on the engine with the builder's name. They're good credentials. The GLC 63 S has some very determined and capable competition, but none of them blend the speed, overall comfort and sheer sensory silliness of the AMG.

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.

As before, the GLC 63 S comes in wagon and couple bodystyles. Little has changed, with just the usual tweaked front and rear bumpers and mildly redesigned headlights.

All the good bits have remained, like the 'Panamericana' grille from the AMG GT monsters, the jet wing-inspired front bumper and plenty of open space to feed the radiators and intercoolers.

Neither the wagon nor coupe is a pretty machine, but no mid-size SUV is much of an oil painting, with the exception of the Jaguar F-Pace.

The 'Night Package' is still a standard inclusion, blacking out various bits and pieces and looking good when allied with the dark alloys. They both look tough, though, which is classic AMG DNA.

Inside is pretty much the same as before, with just two obvious changes. The new Alcantara-trimmed steering wheel, again from the AMG GT, and also on the C 63 S, joins the party with a more expensive look and feel.

And the new MBUX screen is wider and looks much more at home in a $165,000-plus car. It's still a bit old-feeling, but the digital dash adds a bit of techno-style while the garish speaker covers don't.

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.

A family of four will love any GLC. The wagon's extra headroom over the coupe is useful if not life-changing, while the knee, leg and foot room are generous. Front seat passengers enjoy comfortable seating as long as you're not too keen on pudding.

Underneath, the upward sweep of the centre console is a pair of cupholders and a wireless charging Qi pad that will fit larger phones. Under the split armrest is a small but handy console bin, inside which you'll find USB-C ports.

Two more USB-C ports in the rear join a 12-volt socket and there are also climate controls for the rear seat passengers. The centre armrest pops open with a shallow, carpet-lined tray and two cupholders pop out the front. Each of the four doors has a bottle holder, too.

The boot space is unchanged for each bodystyle - 550/1600 litres for the wagon and 500/1400 litres for the coupe. Both have high loading lips, which is something to consider if you're hauling heavy things about or have trouble lifting items to a reasonable height.

As before, we get two bodystyles and the high(er) performance version, the GLC 63 S (a 'base' GLC 63 is available in other markets). Mercedes followed everyone else's lead and realised nobody would buy the skim milk version.

Unfortunately, that translates to the highest sticker price of the three, with the wagon coming in at $164,900, and the coupe at $171,900, before on-road costs.

That doesn't seem to hurt Mercedes too much with other cars in the range, but it's a significant difference. Incidentally, both prices are up by about $3000.

It's loaded, though - 21-inch wheels, multi-zone climate control, air suspension with dynamic dampers, electric and heated front seats, active cruise control, head-up display, reversing camera, around-view cameras, sat nav, front and rear parking sensors, keyless entry and start, electric tailgate, Nappa leather and wood trim, active LED headlights, auto wipers, auto parking, roof rails, sunroof, DVD player, and TV tuner, but no spare tyre, just a repair kit.

A Burmester-branded 13-speaker sound system is powered by Mercedes' spangly MBUX system on a new 10-inch touchscreen, which is much nicer than the old software and hardware combo.

MBUX offers deeper integration with the car's systems. The 'Themes' function is like a series of shortcuts to set the car up for a particular mood, but let's face it, most GLC 63 S drivers are just going to find the 'Race' function and go for it.

MBUX also has Apple CarPlay and Android Auto, but via USB only.

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.

An AMG 4.0-litre twin-turbo V8 brings the thunder, with a massive 375kW and 700Nm of torque. That's plugged into a nine-speed MCT (multi-clutch as opposed to twin-clutch) transmission and Merc's '4Matic+' all-wheel drive system.

With all that power and grip, you'll crack the ton in a supercar-baiting 3.8 seconds. One little point to note is the engine has active mounts.

Should you fancy turning your tinny into a landspeedboat, you can tow up to 2000kg for a braked trailer, and 750kg unbraked.

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. 

Mercedes reckons you'll get 12.2L/100km on the combined cycle which seems laughable at first and then you see what it actually does. To be fair, the car I drove on the launch copped a hammering and was hovering around the 17.0L/100km, with the start-stop and coasting functions playing only cameo roles.

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.

Like any V8-powered AMG, the twin-turbo engine absolutely dominates the GLC 63 S. Even at walking speeds you can feel the serious firepower on offer, just a flex of your ankle away.

The figures are colossal - 375kW (over 500 horsepower) and 700Nm pushing around two tonnes of mid-sized SUV. Its famed bark is bettered only by Jaguar's completely unhinged, and surely borderline illegal, 5.0-litre supercharged V8.

You need to know you've got plenty of tech underneath you to make this stick to the road. The 21-inch alloys are wrapped in 265/40s at the front and 295/30s at the back, Continental Cross Contacts if you're interested.

They should - and would - ruin the ride, but the standard fitment of air suspension means that in normal driving, the GLC 63 S is firm but comfortable. A BMW X3 M is much harder, especially at the rear, going without the complex and heavier air set-up.

The air suspension is probably the pivotal piece of chassis tech that makes this car so versatile. While it's got driving modes up the wazoo - including the new 'Slippery' mode - it's a perfectly agreeable daily driver.

Leave it in comfort, accept that it has a firm ride and you're in good shape for the school run or the commute. You just sail along on a light throttle because there is virtually no turbo lag.

Whack it in Race and you can attack your favourite empty, bendy road with all the grip you could ever need.

The steering is remarkably light and direct for such a chunker and the optional carbon ceramic brakes were never bothered by what I could throw at them.

The V8 roars and spits and crackles, the gearbox shifting seamlessly up and down through the ratios. It's blissfully silly.

In a way, it's a velvet fist in an iron glove - comfortable inside but happy to headbutt the horizon with little provocation.

I'd prefer it if the transmission was a bit more decisive on slow speed shifts and you'll have to prepare yourself for a lot of wearying road noise on long trips. The latter is the price you pay for a ton of grip.

All GLCs have nine airbags, ABS, stability and traction controls, traffic sign recognition, around-view cameras, reversing camera, rear cross traffic alert, blind spot monitor, forward AEB, forward collision warning and tyre pressure monitoring.

There are also three top-tether mounts and two ISOFIX points.

The GLC scored a maximum five ANCAP stars in January 2016.

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.

Mercedes Benz offers a three year/unlimited kilometre warranty with roadside assist which is not really up to scratch for a premium brand. Yes, the cars are complex but they're also expensive, so the investment should come with a commensurate warranty.

Service intervals are generous at 12 months/20,000km (as opposed to the 25,000km of other GLCs) and the capped price servicing means you'll know what you're paying.

Mercedes offers you the choice of an up-front payment or pay-as-you-go. Upfront ranges from $4050 for three services, $6100 for four, and $6850 for five.

If you go with PAYG, three services is a hefty $5000. Basically, each service is at least a grand when averaged out over time and that's pricey.

Service inclusions differ between your chosen method, but only slightly. The pricing includes filters, oil and, unusually, spark plugs and brake fluid, but that's small comfort.
