Mercedes-AMG GLE53 vs MG HS

What's the difference?

The GLE Coupe isn't going to click with a traditional enthusiast but will appeal to a new age of mainstream performance buyers. It's a total tech showcase and you can feel all of those 48-volt benefits from behind the wheel.

Love it or hate its shape, then, you have to appreciate how Mercedes has gone to the nth degree on the details on an SUV it probably could have sold on looks alone.

There are a few niggles with the latest MG HS, for example the annoying driver-attention monitoring and expensive maintenance costs. We’ve not had a full sample of its open-road performance yet either, which may prove more telling.

Yet the HS is shaping up to be one of the most successful product updates of recent years, second only to, I don’t know, the MG3? The family SUV is also backed by a 10-year warranty and, despite the drastic improvements, doesn’t cost a whole lot more than before.

The entry-level Vibe is our pick, there's no need to spend more. It features all manner of safety equipment and a quiet drive but with cloth upholstery that doesn't get all sticky and sweaty in the Australian climate.

The end of 2024 is the tipping point where MG goes from cheap and cheerful to a real headache for established players. Perhaps not for the strongest in the segment like the RAV4 and Nissan X-Trail, but the HS is now an easy car to recommend for a family looking for a spacious SUV that drives their dollar further. The hybrid will boost appeal further when it arrives next year.

Hate the very concept of a large SUV coupe or not, you have to at least agree this second-generation GLE Coupe looks infinitely better than the model preceding it.

This time the Coupe version was front of mind from the outset of the GLEs development and is significantly different from the wagon version in more ways than just a sloping roofline.

The wheelbase has been cropped in 60mm compared to the wagon, and the GLE Coupe is a full 7.0mm wider and 39mm longer than its predecessor.

All this adds up to an imposing and more resolved SUV Coupe. I especially like the way its bootlid flicks up into a spoiler, and how the tail-lights round out the profile nicely.

Still, there's always going to be something a little off about the proportions when it comes to a coupe SUV this big, and it's certainly a re-imagining of what a sporty vehicle should look like.

This car's cabin is almost as confronting as its exterior. Up front you're met with an assault of chrome, a ventilation overload and a totally dominant expanse of screens.

This all hints at the advanced tech which lies beneath, but the real wood and leather trims also elevate the cabin to something you might expect at the tall asking price.

It may appeal to a particular taste and makes the BMW X6's cabin look almost conventional.

Though the previous HS had shapely bodywork, the wheels sat too far in-board and the rear end looked awkward. It’s not the same story with the new model which is designed as a family SUV first, rather than a converted hatchback platform.

Part of the improved looks are better proportions. The new HS is 81mm longer, 14mm wider and rides on a 45mm longer wheelbase yet sits 21mm lower for a sleeker appearance.

The front end takes cues from the new MG3 and ZS design language with a broad grille and thin LED headlights. At the back, MG’s design team references the UK’s capital with ‘Shard’ lighting signatures that also appear in the alloy wheels.

It is still fairly anonymous, though perhaps that comes from a lack of familiarity with the brand. The painted wheel arch cladding and metallic-only paint give it a premium boost.

The biggest improvement is inside, where the HS takes plenty of inspiration from the excellent MG4 electric car with the hexagonal steering wheel (though here with perforated leather finishing), high-set controls and confident lines. It’s a welcome, modern change after the old car’s bloated cabin design.

There are soft-touch rubbery materials in all sorts of prominent places, including on the dash top, front and rear door cards as well as where the driver’s knees rest on the doors and transmission tunnel.

In some ways, the GLE Coupe makes the most of its extra dimensions, but in other more obvious ways, it's quite compromised.

Benz tells us there's now 40 litres of combined cabin storage, and with the large door bins, centre console box, convertible cupholders, and glove box, I'm inclined to believe them.

The brand also told us much of the extra 39mm of body length has gone into the rear passenger space, and this seems true when it comes to legroom.

You definitely notice the decline of the C-Pillar, though, making an otherwise large space feel slightly claustrophobic, particularly with the 53's dark headlining and heavily tinted rear windows.

The almost absurd ride height does make peering over the bonnet a chore at times, although I enjoyed the adjustability and comfort afforded by the front two seats.

In terms of connectivity, front passengers get a plethora of USB-C jacks, a wireless charging bay, and a 12V power outlet. There's no USB-A connectivity, so you'll want to stock up on converters.

Rear passengers benefit from dual USB-C ports in a fold out tray, and also score dual adjustable air vents. Two extra climate control zones can be optioned for rear passengers ($1450), and there's also an exorbitant option package to include two screens and wireless headsets for the full business-class experience in the back seats ('Entertainment Package' - $6000!).

You might be surprised given this SUV's shape, but a lot of thought was also poured into the design of the boot area. Thanks to a large footprint, the GLE 53 Coupe's boot is large at 655 litres, five litres up on its predecessor. It's still a whopping 170-litres down on the wagon version, though.

The boot lip has been lowered significantly to increase ease of use, too.

Our test car did not have a spare wheel, with only an inflator kit or run-flat tyres to be working with. This is despite a large area under the boot floor which, to my eyes at least, could easily have fit a space-saver spare.

There is nothing especially ground-breaking about the MG HS’s front cabin. The cupholders are medium-sized and the door bins have enough storage for a one-litre bottle, so this is no Skoda Karoq when it comes to clever cabin solutions.

Telling a tale of the HS’s Roewe RX5 base car’s earlier 2022 launch (and the staggering development speed of personal technology) the lack of USB-C charging ports is now frustrating with all USB ports regular old-school items. Apple CarPlay or Android Auto phone mirroring requires a cabled connection.

The centre multimedia screen is high resolution with day selectable light and dark modes. It was a little laggy to use MG’s software, however, especially when swiping across menu screens. 

There are four hard shortcut buttons beneath it that can jump to the home screen, activate the HS’s front and rear demister and turn the ventilation on and off.

To adjust the temperature you need to go into the touchscreen, though there is a persistent shortcut on the main menu.

A 12.3-inch digital cluster has several selectable info displays and can show navigation mapping and directions in Excite and Essence trims. 

The seats are comfortable and supportive and it's easy to find a good driving position thanks to power-adjust driver's seat and tilting/telescoping wheel adjustment. The front passenger does not get height adjust, though, and is set too high.

Where the extra size pays dividends is in the back seat which has ample room for passengers beyond 185cm, especially when it comes to leg space. The fold-out armrest is sturdy, too, with twin cupholders. Rear air vents are fitted to only the top-spec Essence.

For baby capsules or child seats the HS has ISOFIX anchors fitted to all three rear seats matched with a trio of top tether points.

The MG HS’s boot is about average for the class measuring 507 litres. It grows to 1484L with the 60:40 backrest folded. For reference, class leaders include the Toyota RAV4 (580L), Nissan X-Trail (585L) and Volkswagen Tiguan (up to 615L with rear seats slid forward). 

There are few amenities, with no 12-volt socket, only one (dim) boot light and no shopping bag hooks. The carpet isn’t bargain basement and the luggage cover is sturdy with additional separated storage compartments below the floor and netted cubbies off to the side. 

MG has also been smart in packaging a space saver spare tyre beneath the boot floor (and a cumbersome Styrofoam piece).

Shock horror, the new HS is 10 per cent more expensive than before… but that still makes it $33,990, drive-away, for the basic Vibe — easily undercutting established rivals from Honda, Mazda, Toyota and others. 

You get a lot for that extra $4000, too, right down to basic presentation. There’s no fridge-like solid white paint with all six hues either metallic or pearlescent for no extra cost. MG even offers the upper trims with the option of an eye-catching tan upholstery colour. 

The three-strong trim line-up starts with the Vibe: dusk-sensing LED headlights, 18-inch alloy wheels, adaptive cruise control, auto wipers, tyre pressure monitoring, a six-speaker sound system, nice cloth upholstery and six-way power adjust driver’s seat are standard.

The Excite sprinkles in 19-inch alloy wheels, perforated synthetic leather upholstery, navigation, fog lights and MG’s 'iSmart' connectivity system for a smart $36,990, drive-away.

The range-topping Essence gains a panoramic sunroof, rear privacy class, a power tailgate, front parking sensors, wireless phone charging, eight-speaker audio, 10-way power adjustable driver’s seat with memory, seat heating, dual-zone climate control, rear air vents and wireless phone charging for $40,990, on-the road. 

The short of it is that, although MG’s prices are up, even the basic Vibe is a more enticing proposition on price than the new Chery Tiggo 7 Pro Urban ($39,990, drive-away) and established Mazda CX-5 Maxx (currently on offer for $37,990, drive-away).

It also is much closer to the popular GWM Haval H6 ($31,990-$37,990, drive-away) — if only MG had brought ventilated seats to the flagship Essence then this mid-sizer would be (almost) sold on paper alone.

Here's where this car gets particularly interesting. It's a hybrid. But not your gran's Prius. It's hybrid in a way which will make you re-think the technology.

Residing under the bonnet is a 3.0-litre, twin-turbo, straight-six engine mated to a very complex looking nine-speed (torque converter) automatic transmission.

One of those two turbochargers is driven by an electric motor rather than the exhaust (in order to provide its peak benefits at the lowest possible rpm), and there's also an electric motor inside the transmission which takes the load off the engine at low speeds and between gears.

This isn't where the 48-volt tech ends, with the GLE 53 also sporting active anti-roll bars and dampers, which significantly adjust the ride and body-roll on-the-fly.

All four wheels are driven via Benz's 4MATIC+ all-wheel drive system.

The new HS petrol has a 1.5-litre, turbo-petrol, four-cylinder engine that develops 125kW at 5000rpm and 275Nm from 3000-4000rpm, with those outputs up 6.0kW and 25Nm on the old car.

MG claims new engine features, including the variable geometry turbocharger, centre-mount variable valve timing and a lighter dual-mass flywheel, add up to a 30 per cent improvement in engine response.

More importantly, the insulation is excellent. You barely hear any unpleasant engine noises out on the road and although the four cylinder’s tone isn’t sexy at full-throttle, it is warm and pleasant enough.

The HS petrol is front-wheel drive only which may rule it out for some buyers, but there is a saving grace. The new seven-speed type dual-clutch transmission behaved itself impeccably on a brief first encounter taking in awkward hill starts and reverse manoeuvres. It’s a huge improvement over prior efforts and more refined than even a Hyundai or Kia dual-clutch.

MG claims a 0-100km/h acceleration time of 9.6 seconds, which is about right for entry-level versions of the HS’s typical rivals.

MG no longer offers a more powerful 2.0-litre turbo but a plug-in hybrid with a punchy 223kW and an all-new full-hybrid option will join the line-up in the first quarter of 2025, details of which are yet to be confirmed.

It's a performance car, so fuel consumption is probably not going to be front of mind for potential buyers. That said, the hybrid tech delivers a surprisingly good number.

The official combined cycle consumption number is ambitiously under 10L/100km at 9.3L/100km.

After three days of (roughly) combined testing and about 300km of distance travelled, our car was showing a dash-reported 14.1L/100km. Not near the claim, but is it really bad for a performance SUV weighing 2447kg? I would argue, not.

The GLE 53 requires the top-shelf 98 RON hydrocarbons to fill its 85-litre tank, giving it a maximum theoretical range of 726km between fills.

In the ADR combined (urban-extra urban) fuel efficiency cycle, the MG HS petrol is rated at 6.9L/100km, emitting 156 grams of CO2 per kilometre in the process. A 55-litre fuel tank gives the HS a theoretical driving range of around 800km.

We weren’t able to get a true read on the fuel consumption but the trip computer showed 8.1L/100km after an hour-long run. It lacks an idle start-stop system and requires 95 RON premium unleaded petrol.

This Benz feels about as imposing from behind the wheel as it is to look at. Straight away, you'll notice you tower over the road. I felt as though I was sitting high enough to be on the roof of passing hatchbacks, so there's nothing traditionally 'sporty' about it from the get-go.

I know you're probably thinking visibility is average with that roofline, and you'd be right. You just can't see much, full-stop, out the back.

Thankfully, an array of sensors and very wide-angle mirrors help with overall visibility, so you won't have to be too paranoid about unseen vehicles in your blind spots.

I'm pleased to report all the technology which goes under this SUV's skin is evident when it comes to the drive experience.

The hybrid tech is ultra-slick and impressive in every department, from trawling in traffic to the curvy stuff and the open road.

The responsiveness of this powertrain is something to be experienced (with the pre-spooled turbo) and the way the hybrid motor in the transmission smooths out shifts removes all the worst characteristics of a traditional torque converter automatic.

One thing to note about the GLE 53 – while it's quick, it's not quite a fire breather. There's no getting around this car's almost two and a half tonne weight, and while I love the smooth feel and note of the 3.0-litre straight six, it's simply not as thunderous or full of theatre as I imagine the 63 S will be.

Despite its height and weight, the altered steering ratios and 48-volt driven suspension and anti-roll systems cause a suspense in belief when it comes to the corners.

And grip levels are certifiably absurd with those gigantic rear tyres also pitching in to do their part to help something this large deny gravity and physics.

It's not all amazing though. You really feel every millimetre of this SUVs width, and at the end of the day there's no getting around it. It just doesn't feel anything like a sports machine in the traditional sense.

When it comes to ride quality, the GLE impresses, but has its limits. Sure there's air suspension at work, but it offers up nowhere near the ride quality of the more comfort-tuned GLC 300e I recently tested.

Seems as though there's an inevitable cost to keeping the GLE feeling well and truly planted at all times.

On the freeway the GLE Coupe is ridiculous in the way it can basically drive itself, so this offers up a real plus for those looking for a balance of performance and sensibility for longer trips.

MG’s launch drive program was too brief to really get under the skin of the HS, which is a shame because the initial signs are extremely positive.

Compared to the old ZS, in which a gumnut hitting the roof was loud enough to distract you from your thoughts, the new car is packed with sound deadening for a vastly more premium experience.

The electronic power steering system has a natural ratio (2.6 turns lock-to-lock) and weighting in 'Comfort' and 'Sport' modes, which cannot be said for rivals such as the Chery Tiggo 7 and Haval H6.

This new HS rides nicely, too, with enough compliance from the suspension without sacrificing body control — at least around town. It has struts up from with a multi-link rear end which is not a given, even in this segment.

There were a few sharp-edged bumps that sent a shock through the body but that is to be expected on Sydney's awful roads. The new HS rides about as well as a Mazda CX-5 and believe us, that is a dramatic improvement.

Visibility out the front and sides are good as is the comfortable driving position, however I wasn’t able to move the driver’s side mirror far enough out for my liking. That’s a small blip in an otherwise strong first showing.

The MG HS has not yet been evaluated by an independent safety testing body such as ANCAP or Euro NCAP.

MG has fitted the new HS with seven airbags, including driver and passenger, front side, side curtain and a centre airbag.

The HS has a long list of active safety and driver assistance features, such as front and rear auto emergency braking with junction detection, lane-keep assist, blind-spot monitoring, adaptive cruise control with stop and go and driver-attention monitoring.

I can’t say all the aids are perfect but the adaptive cruise control and lane-keep assist systems were less intrusive than those in Chery and Haval products.

The regularly-beeping driver-attention monitoring remains a constant frustration as it does across almost every brand at the moment.

Mercedes has recently made a jump to the front of the luxury segment, offering an industry-wide standard of a five-year/unlimited kilometre warranty. Here it is only rivalled by Korean newcomer, Genesis.

Service intervals occur once every 12 months or 25,000km and prices can be pre-packaged at a discount.

A three-year service plan can be had for $2800 ($3500 if you choose to 'fix' the price), four years can be had at $3800, while a full five-year plan will set you back $5200. Not cheap, but then, neither is the car itself...

MG has recently moved to a 10-year/250,000km new car warranty in Australia which covers the HS and is the longest non-conditional offer in the market.

GWM/Haval, Kia and SsangYong remain at seven years while Mitsubishi requires you to service the car at a main dealer for its 10-year guarantee.

This long warranty period should help allay concerns for new MG buyers that the brand stands behind its products.

Less impressive is the cost of maintenance, which adds up to $2354 over five years/75,000km with a particularly steep $936 service at the four-year mark. There’s a big $1647 service at 120,000km, too.
