Mercedes-Benz GLC-Class vs MG ZS

What's the difference?

Like I said right from the start, this new, hybrid version of the AMG GLC63 is technically superior to the model it replaces in every meaningful way. It is faster, more powerful and more fuel efficient and therefore a better performance SUV than the model it replaces.

Is it a better model than the one it replaces? Ultimately that will come down to how much stock you put into the soundtrack and your feelings on an AMG not powered by a V8 engine.

Because if you can see past that, then the AMG GLC63 is an absolutely fantastic performance SUV. Not only does the new powertrain make it faster in a straight line, but the chassis is very well-balanced, making for an engaging driving experience.

For those who can look past the smaller engine they will be rewarded with an incredibly fast and rewarding-to-drive member of the AMG family.

The MG ZS Essence Turbo has a lot going for it. It’s keenly priced, well equipped, spacious and comfortable with good performance, refinement and safety. On the downside, it’s thirstier than it should be, despite a stonking 10-year warranty servicing is relatively pricey and there are some low-level quality concerns. But should it be on your $30-35K small SUV shopping list. One hundred per cent, yes.

The GLC63 is unmistakably an AMG from the moment you first lay eyes on it. That’s thanks to the AMG-specific elements, starting with the grille with vertical strikes and the AMG crest on the bonnet; which is now a signature item for the performance sub-brand.

The GLC63 is also fitted with the Night Package II design kit; this adds a darkened grille and black chrome badging to further enhance its visual appeal.

The AMG-specific alloy wheels and more aggressive stance do mean the GLC63 stands out from the rest of the GLC range, helping it look fast even when it’s standing still.

From its narrow, acutely angled headlights to the deep gill-like inlets sitting either side of its large grille, the MG ZS conforms to the currently popular 'make it look a bit like a shark’ school of front-end car design.

From the nose back, this five-seater’s overall proportions follow a familiar small SUV template, without any significant pulse-quickening deviations.

And by the time you get to the back, the rear door and tail-light treatment is borderline generic. Replace the MG octagon with any number of other mass market automotive logos and you wouldn’t look twice.

That said, the shape is well balanced, the standard 18-inch rims fill the wheel arches nicely and our test car’s rich and lustrous ‘Diamond Red Metallic’ paint finish drew multiple compliments during our time behind the wheel.

The interior is simple with some cool touches thrown in, like the aero-style geometric vents with a bright, brushed finish around their leading edge, a neatly integrated 12.3-inch media touchscreen in the centre of the dash and another of the same size in front of the driver for instrumentation.

There’s a sensible mix of physical and digital controls for major functions and the steering wheel is flat on the bottom and the top. It adjusts for height, but disappointingly, not reach.

Materials around the dash and doors are soft-touch, which is nice, and the synthetic leather seat trim, with lighter contrast stitching and perforated centre panels looks and feels good.

Inside the GLC63 is clearly a derivative of the rest of the range, with its C-Class-inspired design and layout, but there’s enough AMG-specific elements to ensure it looks and feels special. This starts with the AMG steering wheel, which comes not only with a thick rim wrapped in Alcantara, but also some AMG special dials to adjust the various performance settings for the powertrain, suspension and transmission.

Then there are the AMG-specific seats, which look good and offer good support for the driver and front seat passenger. The rear seats offer decent space for what is a mid-size SUV, with room enough for two adults or teenagers or three smaller kids.

Those in the back aren’t particularly well looked after though, with only rear air-con vents and small door pockets but no USB charging ports or other small item storage.

The boot is 590 litres, down from 620L in the rest of the range, thanks to the addition of the rear-mounted electric motor. There’s also no room for the temporary spare the rest of the GLC range gets and instead you have to make do with a puncture repair kit.

At just over 4.4m long, a fraction more than 1.8m wide and a little over 1.6m tall the MG ZS is a little larger than the small SUV norm, but conversely its 2610mm wheelbase is shorter than average.

That doesn’t appear to impact interior packaging, however, with plenty of room up front and more than adequate breathing space between driver and co-pilot.

For storage, there’s a medium-size lidded box (which doubles as an armrest) between the front seats as well as a pair of cupholders in the broad centre console, with a bay for wireless device charging near the gear-shift.

The glove box is generous, there are bins in the doors with room for decent size bottles and a drop-down sunglasses holder sits overhead.

In the back there’s heaps of head and legroom for me (at 183cm) sitting behind the driver’s seat set to my position.

Three full-size adults will be getting a little too up close and personal for anything other than short-ish trips, although a trio of up to mid-teenage kids will be right at home.

Big tick for adjustable air vents at the back of the front centre console and storage options include map pockets on the front seatbacks and bins in the doors with room for up to medium-size bottles.

No fold-down centre armrest in the back is a miss given one would typically feature a pair of cupholders.

Power and connectivity options in the front console include a USB-A plug (for power and media connectivity), a USB-C socket (power only) and a 12-volt outlet. Points, too, for a USB-A near the rear view mirror for a dashcam and another for back seaters. But no 12V in the boot (which can be handy when camping or picnicking).

What the boot does have, however, is a class-competitive volume of 443 litres with the 60/40 split-folding rear seat upright. Enough to swallow the large (124L) and medium (95L) suitcases from our three-piece set.

Remove the cargo tray and the smallest (36L) case will find a home, too. Boot space expands to 1457L with the rear backrest lowered.

The space is well lit, there are tie-down anchors to help secure loose loads and handy wells behind the rear wheel tubs on both sides. A space-saver spare sits under the floor.

And if you’re keen on towing, you might want to think twice about the ZS as it’s limited to a 500kg trailer (braked or not).

Cost of entry for the MG ZS Essence Turbo is $31,990, drive-away, which is a pretty sharp price in one of the most hotly contested segments in the Australian market. Worth noting the sizeable gap to its Essence Hybrid+ stablemate at $40,217, drive-away.   

That low-$30K positioning puts the Essence Turbo up against a swag of well-credentialled rivals including the GWM Haval Jolion Premium Hybrid 2WD ($32,990, drive-away), Hyundai Kona 2WD ($32,500), Kia Seltos Sport FWD ($33,050), Mazda CX-30 G20 Pure FWD ($33,940), Mitsubishi ASX LS ($30,490), Nissan Qashqai ST FWD ($34,665), Subaru Crosstrek 2.0L ($34,990) and Toyota Corolla Cross GX 2WD ($33,980). All prices before on-road costs unless otherwise noted.

To grab a value-for-money edge against this challenging field the MG needs more than just an attractive price tag. And the ZS Essence Turbo boasts an impressive standard features list.

Over and above the safety and performance tech we’ll get to shortly, included are 18-inch alloy wheels, climate control air, multiple drive modes, a 12.3-inch multimedia screen and 12.3-inch digital instrument cluster, keyless entry and start, a panoramic sunroof, synthetic leather trim, six-way power adjustment for the driver’s seat, six-speaker audio, rain-sensing wipers, Android Auto, Apple CarPlay and Bluetooth connectivity as well as digital radio.

There’s also auto LED headlights (as well as LED DRLs and tail-lights), a leather-trimmed steering wheel, built-in sat nav, adaptive cruise control, a hi-def 360-degree camera view, a reversing camera and auto-fold exterior mirrors. 

At the MG’s price point - drive-away, remember - that’s a strong basket of standard fruit.

This is what lies at the heart of the AMG GLC63’s success or failure. As I mentioned at the beginning, the previous generation’s 4.0-litre twin-turbo V8 has been replaced by an F1-inspired plug-in hybrid powertrain.

But don’t think that means AMG is suddenly focused on efficiency over performance. When AMG says the powertrain is inspired by the brand’s success in Formula 1 racing, what it means is the battery and electric motor provides a significant performance boost to support the internal combustion engine, not just save fuel.

To that end the combination of the turbocharged 2.0-litre four-cylinder petrol engine and the rear-mounted electric motor produces an impressive 500kW and 1020Nm. That’s a massive jump over the 375kW/700Nm made by the outgoing V8.

As its name implies, the ZS Essence Turbo is powered by a 1.5-litre, turbo-petrol, four-cylinder engine sending 125kW (at 6000rpm) and 275Nm (at 4500rpm) to the front wheels via a continuously variable auto transmission (CVT). 

It’s an all-alloy unit, featuring direct fuel-injection as well as variable valve timing on the intake and exhaust side which helps optimise engine response.

Mercedes makes no secret that the battery is designed for performance, not saving fuel. It only has a 14km EV range but can recharge quickly on the move to provide a power boost when needed.

But despite all that, the GLC63 is actually significantly more fuel efficient than the old V8, using a claimed 7.3L/100km, which is a massive 4.9L/100km improvement over the old model. Although, on our day-long test drive we didn’t manage to come close to that claimed figure and instead saw returns around 11L/100km, albeit after a lot of spirited open-road driving.

The ZS Essence Turbo’s official fuel consumption figure on the combined (urban/extra-urban) cycle is 6.9L/100km, the 1.5-litre turbo four-cylinder engine emitting 161g/km of C02 in the process.

Over a combination of city, suburban and some freeway running we saw an average of 9.6L/100km, which is getting up there for a small SUV. And bear in mind you’re looking at a minimum fuel requirement of 95 RON premium unleaded.

Worth noting its roughly 25 per cent more expensive ($40,217, drive-away) ZS Essence Hybrid+ sibling is not only far more powerful, but significantly more frugal, with an official combined cycle figure of 4.7L/100km. Mind you, it would take a while for that economy to make up for the more than $8K purchase price difference.

Based on the car’s 55-litre fuel tank, theoretical range between refills is close to 800km, which drops to just over 570km using our real-world test consumption number.

Anyone who still believes in the adage ‘there’s no replacement for displacement’ hasn’t driven a modern turbocharged and hybridised engine. The GLC63 is a demonstration of the metaphorical and literal power of modern technology, combining an extremely efficient and potent internal combustion engine with an electric motor to make enormous real-world performance.

To be blunt, the GLC63 feels like a rocketship out of corners, launching with a ferocity and relentlessness the old V8 simply can’t match. It shouldn’t come as a surprise, a mid-size SUV with 1020Nm was always going to have plenty of performance, but even so it’s a shock to the system every time you give the GLC63 full throttle. Officially AMG claims it takes just 3.5 seconds to run 0-100km/h and has an electronically limited top speed of 275km/h - mighty impressive figures for a five-seat mid-size SUV.

To help get all that torque to the road, AMG deploys torque distribution technology that allows for it to be split an even 50/50 front/rear all the way to 100 per cent to the rear tyres.

Other technologies deployed to enhance its handling include AMG Ride Control suspension with adaptive damping and rear-axle steering. There’s also eight AMG Dynamic Select driving modes and four AMG Dynamics settings (Basic, Advanced, Pro and Master), so it’s a complex vehicle that is designed for the enthusiast.

While it’s easy to drive around town, once you get out on the open road you can really get a sense of the GLC63’s performance potential. Beyond just its powertrain the suspension offers good body control and the rear-axle steering helps it feel agile and responsive. 

It’s not perfect though. At times the complexity of the system does lead to some hesitation when you put your foot down. It certainly lacks the linear power delivery of the old V8 and makes for a slightly trickier driving experience at times.

As for the sound, which is one of the biggest elements missing from the V8, Mercedes has added AMG Real Performance Sound, which features a pressure sensor in the exhaust that picks up on the engine note and plays it through the speaker system. It certainly helps make for a louder, more noticeable engine noise, but it still sounds more like an A45 than the previous GLC63 and for many would-be buyers, that’s a major turn-off.

Stand-out qualities once behind the wheel of the ZS Essence Turbo are its comfy ride, responsive throttle and low noise levels.

Although MG doesn’t quote a 0-100km/h acceleration time, you can expect triple figures to come up in around eight seconds, which is rapid enough for the cut and thrust of city traffic.

And power delivery is satisfyingly linear. There are no laggy clues that a turbo engine resides under the bonnet, although maximum pulling power doesn’t arrive until 4500rpm, which is unusually high for a forced induction engine.

But there’s still plenty of oomph low down and the CVT auto is one of the better examples, keeping the engine on the boil nicely without any engine droning drama. Freeway cruising is a breeze.

That said, a pair of steering wheel paddles for stepped manual ‘gear’ changes would be a nice addition to take maximum advantage of the engine’s willing nature.

But you have to be realistic in terms of standard mechanical spec at a low-$30K price point. If you're in the mood, the switch to ‘Sport’ mode revs things up, though.

Suspension is by struts at the front and torsion beam at the rear, the car remaining well balanced during quick lane changes or through sharp corners.

Tyres are 225/50 Giti ‘GitiComfort’ on 18-inch alloy rims and despite that sizeable wheel diameter (for the class), a relatively cushy tyre sidewall height also helps with overall refinement.

The front seats are comfortable and supportive enough, although the small gap between the headrest and my noggin meant I was constantly bumping against it. Kind of annoying but it may have more to do with my XXXL melon than the restraint design.

The electrically assisted steering is accurate and road feel is fair, although the squared-off wheel design takes a bit of getting used to and its adjustment is stuck in 1994, shifting for height but not reach.

Braking is by discs all around (ventilated front) and they wash off speed effectively with a progressive pedal action.

An 11.2m turning circle isn’t exactly tiny, although all around vision is clear, and parking, assisted by the 360-degree camera view, reversing camera and rear parking sensors, is straight forward.

Niggles? The handbrake has to be applied manually, which may sound like a classic first-world problem, but the majority of new cars now apply it automatically when parked.

A ‘bing-bong’ overspeed warning, related to the traffic sign recognition function, is infuriating, as is the need to shuffle through multiple menus every time you drive the car to turn it off. Hyundai and Kia have recently minimised this issue with a short-cut button, which we suggest MG takes a close look at.

And one misty morning I noticed the bottom four rows of the rear screen demister had gone out on strike, which doesn’t feel great from a quality point-of-view.

In a similar vein, I recently spent time in the ZS Hybrid+ and thought one of the suspending cords on the rear parcel shelf hadn’t been properly fixed. Turns out the small plastic fitting holding the string had pulled out of the tailgate door and wouldn’t stay put when pushed back in. Awkward.

ANCAP has assessed the MG ZS but only hybrid variants. So, even though that resulted in a maximum five-star score, this turbo model is technically untested.

No surprise then that the car is equipped with a full suite of active (crash-avoidance) tech including auto emergency braking (AEB), adaptive cruise control, lane change and lane keeping assist, blind-spot monitoring, driver attention alert, forward and rear collision alert, rear cross-traffic alert, tyre pressure monitoring, a 360-degree camera view and more.

And it’s important to note these systems are well calibrated in that any micro corrections they make are only sporadic and relatively subtle, even in adaptive cruise mode where less refined systems are often found out.

Then, if despite all that, a crash is unavoidable there are six airbags onboard - dual front, front side and full-length curtain. Would be nice to see the increasingly common front centre bag but it’s MIA for the time being.

There are three top tether points for child seats across the second row with ISOFIX anchors on the two outer positions.

The GLC63 is covered by Mercedes Australia’s usual five-year/unlimited kilometres warranty.

As for maintenance, Mercedes offers service plans, spanning three to five years. Three years will cost you $5025, $6455 for four years and five years is priced from $7180. Servicing intervals are 12 months or 20,000km, whichever comes first.

MG covers the ZS with a 10-year/250,000 km warranty which is way ahead of the mainstream market norm of five years/unlimited km. 

Roadside assistance is complimentary for the first 12 months and automatically extended for an additional year after each annual service at an authorised MG dealer, for the duration of the warranty. Nice.

Scheduled servicing is every 12 months/10,000km, the latter measure a little short of the more common 15,000km distance.

MG’s ‘Precise Price’ program sets out maintenance pricing for the duration of the warranty, the lowest cost over that 10-year period being $302 and the highest $1463, for an annual average of $686.60. 

Pricey when you consider a similarly specified Toyota Corolla Cross averages $398.68 per service over the same period.
