MG HS vs Porsche Cayenne

What's the difference?

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.

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

Of all the super SUVs I've piloted, the Porsche Cayenne Turbo GT is the best all-rounder in terms of performance, comfort, cabin technology and style.

As a family car it's roomy, practical and easy to use and drive daily.

As a performance car the Turbo GT is stupidly quick, with the agility of a sports car. Sure, a 911 would leave it behind on a twisty race track, but this SUV is close to having that sportscar experience and keeping your family, as well.

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.

This might be a personal thing but to me nearly all Porsches look better from the back than the front.

It's the wide stance and powerful haunches, the hunkered down suction-capped-to-the-road look that does it for me and the Cayenne Turbo GT, despite being an SUV, passes this important Porsche checklist item.

The GT aero kit only serves to make this SUV look more of a beast, and the gold-bronze looking satin Neodyne wheels are a Porsche theme that I've not always been a fan of, but I get the historic connection.

If only the Turbo GT could look a little less like other Cayennes from the front. This is the king of the SUV range and despite the apron and bumper already being exclusive to this model, there should be more.

Vents in the wheel arches, carbon bonnet with nostrils GT3-style perhaps? Or is that going too far? If you do want something more lairy then there's always the Urus.

The Cayenne Turbo GT's cabin is stunning in its plushness and modern surprises such as the passenger display, the hoodless instrument digital cluster, the lashings of Race-Tex upholstery everywhere. It's perfectly Porsche. High-performance meets high-end.

It's also highly practical. Let's talk about that.

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).

The Porsche Cayenne Turbo GT only makes one compromise on practicality and that's the removal of the middle seat in the back, which, with just two kids isn't used all the time but on average we might need it once a week for school mates and cousins.

Instead of a middle seat there is a shallow tray, which will fit a phone or in our case leaves and rocks found at the park.

So, yes, the Turbo GT is a four-seater only, but this is a spacious, large SUV with good head and legroom, wide-opening doors for easy entry and exit, and air suspension which can raise and lower the height for easy access.

Storage is excellent with enormous door pockets in the front and back and there are four cupholders.

There's a wireless phone charger in the front and two USB-C ports as well, plus two USB-C sockets in the back.

Four-zone climate control means the kids in the back can set their own temperatures. They also have heated seats.

I was disappointed to see there aren't sunshades for the rear windows - pretty vital in Australia where it feels like we're only about 50 metres away from the sun.

The Turbo GT's 576-litre boot just managed to fit our pram and a week's shopping, which is our minimum standard for living. Any more space is a bonus.

The Turbo GT is the king of Cayennes, so it shouldn't surprise anybody that it's also the most expensive with its list price of $364,700.

Lamborghini's Urus lists for $409,744  and is the Cayenne Turbo GT's not-so-subtle Italian cousin, sharing the same platform and engine.

Both are in my mind the best performance SUVs on the planet. It just depends how conspicuous you want to be.

Then there's Bentley's V8 Bentayga which isn't blessed with the Porsche's good looks but would still be all over the Cayenne if the two happened to meet at a race track.

So, why is the GT Turbo the king of the Cayennes? What makes it better? For all the reasons you'd think - it's the fastest, most powerful, most luxurious and most equipped Cayenne in the range.

We'll get into mind-bending engine and performance specs soon, but first let me take you through the standard features on a car that's anything but standard.

Coming standard and exclusively to the Turbo GT are 22-inch 'GT Design' wheels in satin 'Neodyne' with full-colour Porsche centre caps, an active rear spoiler, Turbo GT front apron, dual titanium exhaust, rear apron with diffuser, 'SportDesign' side skirts, wheel arch extensions, a lightweight carbon roof and tinted LED HD-matrix headlights.

Inside, and also exclusive to this grade, is the 'GT Interior Package' with 'Race-Tex' upholstery throughout with 'Deep Sea Blue' stitching on the front seats and centre console and the armrests and dashboard.

There's also the 'Carbon Interior Package' which includes dashboard and door trim elements.

Race-Tex trim is applied to the 'GT Sports' steering wheel, roof lining and gearshift, too.

The adaptive active air suspension, which can lower the car by 15mm, is standard and only available on the Turbo GT, too.

The soft-close doors are standard (a cost option on lower grades), as are the stainless steel pedal covers.

The rest of the features are also found on lower grades and include the 12.65-inch digital instrument cluster, head-up display, proximity unlocking, 12.3-inch multimedia touchscreen with sat nav, wireless Apple CarPlay and Android Auto, digital radio, a 10-speaker Bose sound system, heated front seats, rear privacy glass and an auto tailgate.

Four-zone climate control is standard on the GT Turbo, too, and so are heated rear seats.

Our car had several options fitted such as the front passenger display ($2860) and the Deep Sea Blue Accent Package.

The passenger display is a crowd pleaser, but as a family car my kids felt like they were missing screens in the back seats, too. Well, in my day...

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.

As a middle-aged parent with two children, a Porsche that I don't have to crawl into and out of like a cubby house is a great thing.

What's even better is that this ‘easy access' Porsche is every bit as brutally powerful and fast as the quintessentially ‘pure' Porsche, the 911. Actually, it's more powerful and faster.

The Turbo GT's twin-turbo 4.0-litre V8 petrol engine makes 485kW and 850Nm with drive going through an eight-speed transmission to all four wheels.

In comparison, a Porsche 911 GT3 RS, arguably the most brutal and anti-social 911, has 386kW/485Nm.

I haven't made a mistake. Those are the real numbers. And it's only when you step on the accelerator in the Cayenne Turbo GT, and it feels like somebody's sat down on your chest, that you realise what a big deal this is.

That is such a colossal amount of oomph that this 2.2-tonne family SUV can accelerate from 0-100km/h in 3.3 seconds.

The 911 GT3 RS can do it in 3.2 and it has a roll cage and a fixed rear wing the size of a bedroom door.

And yes, we're now coming into a digital age where Teslas and other electric SUVs are quick, too, but can they go around corners like a Porsche Cayenne Turbo GT?

Do they have the same rumble and roar as a twin-turbo V8 that's terrifying and enticing at the same time.

The correct answer is, absolutely not.

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.

Seriously? This is a 2.0-tonne twin-turbo petrol V8 with a 90-litre fuel tank. Even the Porsche specs sheet doesn't understand the question because in the column for fuel efficiency there are three letters - tbc.

My own testing saw me record 22.5 L/100km at the fuel pump, which means I enjoyed driving the car very much.

A little digging around reveals Porsche globally claims the Turbo GT will use 12.6L/100km, over a combination of open and urban roads.

You might not have as much fun as I did but easing back a little might get you closer to the 700km of range this more frugal consumption figure appears to offer.

While efficient it isn't, I'm not going to mark the Turbo GT too much here because compared to its petrol rivals the fuel consumption is what I'd expect from such a high-output heavy SUV.

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.

Never have I met a car this powerful and superbly athletic that is as pleasurable to drive alone on great, fast roads as it is to pilot at 50km/h in the suburbs with a family on board.

It exceeds my understanding of engineering that something this large can move so quickly. That in an instant can turn and tip into a corner with such precision and effortlessness.

Yet it can switch seamlessly and happily to coping with speed bumps and potholes, delivering a ride so comfortable it'll send babies off to sleep. And it did.

The only issue, and this is such a tiny thing, is the dash-mounted gearshift, which means having to reach up and select Drive or Reverse or Park, which, when executing a three-point turn, is necessarily frustrating.

Still, I'm giving the Turbo GT a 10 out of 10 for driving under all conditions, and we didn't even go off-road, which of course you can do, as long as it's not too wild.

The Porsche Cayenne Turbo GT hasn't been locally crash tested and so doesn't have an ANCAP rating.

That's quite normal for super high-end cars. But, when this third-generation model first arrived in 2017 it was tested by ANCAP's European equivalent, Euro NCAP, and was awarded the maximum five stars.

There's AEB which operates at city, urban and highway speeds, and lane keeping assistance, and lane change assistance which is a form of blind-spot warning, and adaptive cruise control. You can option rear cross-traffic alert, as well.

A space saver spare wheel is under the boot floor.

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.

The Cayenne Turbo GT is covered by Porsche's three-year, unlimited kilometre warranty, which is lagging behind in terms of duration even compared to other luxury brands such as Mercedes-Benz, which offers five years.

Servicing is recommended annually or every 15,000km, although there isn't a capped price maintenance plan with final costs determined at the dealer level (in line with variable labour rates by state or territory).
