Porsche 911 vs MG MG4

What's the difference?

The more things change, the more they stay the same. The t-hybrid might be an entirely new propulsion system for the 911, but the net result is unchanged – power, poise and performance on tap.

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

The MG4 was a game changing electric car, resetting the price benchmark while also being a very good small car in its own right. But as we discovered when we tested the rest of the range, the MG4 is a car that gets more compelling the cheaper it is. The $38,990 MG4 Excite 51 is arguably the pick of the range given its value equation.

But that’s not to say the MG4 XPower isn’t a good car. It’s a very quick car that will play the role of daily driver and weekend fun machine well. Just not quite as well as its petrol-powered rivals.

This facelift debuts a revolutionary exterior design that has completely reshaped the 911.

Just kidding. If it ain’t broke and all that. The front air vents and exhaust have changed, the former now an active intake system that deploys via vertical flaps, but elsewhere it’s largely evolution over revolution.

Instead, Porsche has focused most of the updates in then cabin. In here, you’ll find a new digital instrument panel, they’ve changed some of the levers and the steering wheel.

In true Porsche fashion, though, this new 911 mimics the older versions in that it's one of the more intuitive cabins you’ll ever sit in. Everything feels as though it’s exactly where it should be, and all feels entirely centred on the driver.

What really stands out about the design is… that not much stands out about the design. At least in differentiating the XPower from the rest of the MG4 line-up.

There are no pumped out wheel arches or a bigger, sportier spoiler that makes it look different in the same way a GR Corolla won’t be mistaken for a regular Corolla hatch.

Instead, the XPower has the same 'Energetic Agile' silhouette and includes the same ‘Active Intake spoiler’ at the front and the ‘Twin-Aero’ rear spoiler that’s the same as the Essence models.

There are some differences though, including more pronounced styling on the sides of the doors. It doesn’t add any performance benefit but creates a slight visual difference between the models in the range.

Surprisingly, there is very little to signify that this is the sportiest XPower model, with a distinct lack of badging - inside and out. In fact, the only visual clue that this is the XPower is on the bright orange brake calipers. Or, to be more accurate, brake caliper covers.

These are just lightweight metal covers that make the MG4 braking hardware look bigger than it really is, so it’s a bit of visual trickery from the MG designers.

This probably falls under the ‘next question, please’ umbrella, given that, while the Porsche 911 is known for a lot of things, vast acres of space with loads of practicality perks just ain’t a part of its portfolio.

The new 911 measures a not-insubstantial 4533mm in length, 1852mm width and around 1294mm in height, and it rides on a 2450mm wheelbase. Luggage space is a paltry 135 litres under the bonnet, plus whatever else you can fit in your pockets.

There’s seating for four, should you not like the people you’re squeezing back there very much, but really the 911 is best enjoyed as a two-seat proposition – which is why you can also delete the backseat, should you wish.

It also weighs a minimum 1595kg, or up to 1745kg, but Porsche says the hybrid tech only adds about 50kg to the total kerb weight.

As with the exterior, there’s not a lot to differentiate the XPower from the rest of the line-up. No bright red Civic Type R style interior treatment here. MG has opted to carry over the minimalist design that no doubt contributes to the sharp pricing.

Probably the only notable difference is the seat trim, with the XPower model getting a combination of synthetic leather and suede for a sportier look and feel. But the rest is largely the same, which detracts slightly from its hot hatch credentials.

On the plus side, the MG4 cabin is generally a well-designed interior space, which is a positive for the XPower’s hot hatch argument, as the idea behind the ‘hot hatch’ is that it can be a practical car during the week and fun on the weekends. 

There’s good room for passengers and luggage, in large part thanks to the relatively slim battery design that frees up more cabin space. Front seat occupants will enjoy the space and good visibility on offer.

Small item storage is very good in the MG4, with a pair of cupholders, a large, flat lidded tray (with one USB-C and one USB-A outlet just above) and the centre console box all fitting between the front seats.

There’s also a wireless smartphone charging pad that sits halfway up the centre fascia, next to the rotary gear selector, but it’s a shallow space so your phone will almost certainly fly out as soon as you begin cornering vigorously.

However, once again highlighting the ways MG has saved money to keep costs down, the back seat accommodation isn’t anywhere near as well appointed.

While the space is adequate for a small hatch, there are no cupholders, no air-conditioning vents and no fold down armrest for those in the back. All they have access to are some pockets on the back of the front seats, including a pair of small ones high on the seat, seemingly designed to accommodate your smartphone.

In another positive for its hot hatch practicality, there are ISOFIX points on the outer rear seats, neatly covered by leather pieces for a cleaner look when you don’t have kids.

As for the boot, the XPower measures the same 363 litres with the seats up which is unchanged from the rest of the MG4 line-up.

Disappointingly, there’s no obvious place to stow the charging cable, even though it comes in a small, neat bag. This is a worryingly common trend with these early generation EVs that shows a lack of practical thinking from the designers.

The MG4 has no under-bonnet storage either, so it feels like a few wasted opportunities for what is a bespoke EV design.

While we’ll dive into performance and the headline figures of the XPower soon, there’s another number that’s arguably more impressive - the price.

The MG4 XPower is priced from $59,990 (plus on-road costs), making it only $4000 more expensive than the range-topping MG4 Essence 77.

More importantly, when compared to the likes of the $72,600 Honda Civic Type R, $68,990 Volkswagen Golf R, $64,190 Toyota GR Corolla and $57,990 Subaru WRX tS Sport the XPower is arguably one of the first EVs to achieve true price parity with its internal combustion engine rivals (although the Cupra Born starts at $59,990 so it can argue the same).

Beyond the performance upgrades we’ll detail below, that price brings a well-equipped car.

The XPower comes with 18-inch alloy wheels, LED headlights and tail-lights as well as vehicle-to-load (V2L) functionality.

It also comes with a six-speaker sound system, Bluetooth, navigation, Apple CarPlay and Android Auto, a wireless smartphone charging pad and synthetic leather and Alcantara trim. 

There’s the 'MG Pilot' safety package included as standard as well, but we’ll detail that below.

The 'Hunter Green' hero paint colour is exclusive to the XPower in the MG4 range, and is reportedly inspired by an MG land speed record car the legendary Sir Stirling Moss drove in the 1950s.

A new (or at least, massively altered) 3.6-litre petrol engine has been developed for this T-Hybrid, which combines with two electric motors to produce a total 398kW and 610Nm. It’s only available with Porsche’s very good eight-speed Porsche Doppelkupplung (PDK) automatic, largely because the brand admits it would be… well… unpleasant to drive as a manual.

Now, there is lots of magic at work here, and I don’t want to bore you, but the Porsche setup sees a lightweight 1.9kWh battery placed basically in the middle of the front axle, and a 12-volt battery now behind the front seat. Then, a tiny e-motor lives as part of the gearbox (it’s just 55mm long) and delivers up to 150Nm at low speeds to supplement the petrol engine.

It’s joined by what Porsche calls an “electric exhaust gas turbocharger”, which essentially removes the spooling time from the turbo, delivering instant power.

The aim of the game here is excitement, not efficiency, and the launch-control-aided spring to 100km/h takes just 3.0 seconds. And it somehow feels, and sounds, faster.

The latter being important, with Porsche aware that if the new powertrain didn’t sound good, "nobody would like it”.

This is arguably the biggest single difference between the XPower and the rest of the MG4 line-up. Unlike the others that have a single, rear-mounted electric motor, the XPower adds a second motor on the front axle.

This has an obvious impact on the performance, boosting it from the previous best of 180kW to an impressive 320kW/600Nm.

Having motors on each axle also means the XPower is all-wheel drive, so it has little trouble transferring all that grunt to the road.

So much so that the MG4 XPower is the equal quickest hot hatch on the market (at the time of publication), taking just 3.8 seconds to run 0-100km/h; matching the Audi RS3, with its turbocharged five-cylinder engine.

Porsche in Australia is yet to lock in local fuel use for the Carrera GTS T-Hybrid, but international testing has it at 10.5-10.7L/100km, C02 emissions of between 239-244g/km. 

Those aren’t exactly Toyota Prius numbers. But again, that was never Porsche’s intention. The electric power on offer here is intended to improve acceleration, not fuel use.

It’s fitted with a 63-litre fuel tank, which should deliver a driving range of around 600km per tank.

Interestingly, the XPower is not fitted with the biggest battery in the MG4 range, forgoing the 77kWh version in favour of the 64kWh option.

In the ‘standard’ rear-wheel drive MG4 Excite 64 model this battery can provide up to 450km of range (on the WLTP cycle) but in the XPower that figure is reduced to 400km.

While that’s well short of the 530km offered by the long-range Essence 77 model, it’s still a respectable amount of driving range and should suit your typical hot hatch buyer, who knows performance typically comes at the expense of efficiency.

Our test drive was limited to just two days, so we didn't have the chance to live with the XPower for an extended period, but it managed to make it this reviewer’s preferred hot hatch playground on the edge of the city and back again to home with more than 50 per cent of the battery charge remaining.

This was a trip that included a lot of urban driving, some highway and then some ‘spirited’ running on the twisty road, so there’s enough range from the XPower to meet most buyers' needs.

Across almost seven hours of driving, the MG’s trip computer was claiming an average energy use of 18.6kWh/100km. To replenish the batteries, a 140kW DC charger will take just 30 minutes to take them from 10 to 80 per cent.

The V2L is another nice addition, which allows you to draw power from the battery, if needed, to run small electrical appliances.

The XPower is hardly a car for camping but, for example, if you decided to take it to a track day and want to plug in a kettle to make a hot drink, you can literally plug it into the car. Handy!

Porsche did just about the Porschiest thing to ever Porsche in launching the 911 Carrera GTS T-Hybrid, in that we piled into cars in Melbourne, drove the many, many hours (well, it feels that long, at least) to the Phillip Island race circuit, beat the hell out of the cars on track and on the drag strip for several hours, then trundled back out on the road and drove them back to Melbourne.

The subliminal messaging here is pretty clear. This new 911 might have a new powertrain, but it can still deliver the road-track-road experience without breaking a sweat — or, more importantly, without breaking any expensive bits.

So let’s do this in order, shall we? On the road, this new 911 is every bit as sweet as it has ever been. Comfortable, quiet enough when you want it to be, and — save some road noise from those big wheels – quiet enough to let you forget you're driving something with one of Peter Dutton’s nuclear reactors hidden beneath its svelte metal work.

Mind you, that T-Hybrid powertrain will happily remind you of its presence every time you press the accelerator in anger, the exhaust erupting into life and the 911 genuinely rocketing into the future, but stay gentle with your inputs and this hybrid 911 is a genuinely comfortable, genuinely liveable daily driver.

Its split personality appears when you rumble out onto a race track though, where you quickly discover the electrified, and electrifying, Porsche is properly, properly rapid, both in a straight line or around Phillip Island’s fast and flowing circuit.

It’s so rapid, in fact, that it feels most closely related to a performance EV, like the Taycan. Of course it is louder and more engaging, but that’s the best way I can think of to describe the instant power on offer here. There’s no ICE-like lags or lumps in the way that 398kW and 610Nm finds its way to the tyres and into the tarmac. Instead it’s just this constant, savage flow of power that never seems to let up.

Porsche says this new powertrain is about 50kg heavier, but you’d need to be plugged into the race track like its the Matrix to ever feel it, with the T-Hybrid feeling lithe, grippy and athletic, aided by near-perfect steering, the best automatic gearbox in existence, and exactly zero roll through the body. In fact, the only thing that really moves when cornering hard in this new 911 is the driver, and I genuinely got out after several laps with a sore neck from trying to stay vertical.

Downsides? Well, it’s faster in a straight line (it will be some 7.0m further down the road after 2.5sec when compared to the older GTS) and faster around corners (8.7sec faster around the Nurburgring than its predecessor), but there’s something delightfully analogue about the outgoing car, which also manages to feel more aggressive under heavy acceleration, too, owing to the little ebbs and flows of power, and after driving both back-to-back, I still can’t decide which one I like more.

The real question about the XPower is not if it’s quick, because all EVs and especially those with dual motors tend to be very rapid in a straight line, but how it handles itself on a twisty road.

That’s what separates a good hot hatch from a great one, but it’s also an area EVs have struggled in, because the combination of silence, weight and just the fact they’re new and different tends to mean they lack the driving engagement of more established competition.

Hot hatches also need to play a dual role, as daily transport and weekend fun machine, so that’s another factor to consider.

So, how does the MG4 XPower stack up? Well, the unsurprising news is it’s very, very quick. The acceleration is ferocious and really shoves you back in your seat, leaving you in no doubt that it will leave most of its hot hatch rivals (with the exception of the Audi RS3) in its dust.

When the going gets twisty though the XPower feels like it lets its rivals catch back up. There are different driving modes and switching to ‘Sport’ and reducing the regenerative braking makes a notable difference to the way the XPower handles.

The steering gets heavier and it will roll and coast into corners more like a petrol-powered hatch. It makes for a very competent car, with direct steering and good road holding… but not a great hot hatch.

It lacks the engagement and excitement that the best hot hatches offer. For example, the steering gets heavier in Sport mode, but doesn’t provide any more feedback to the driver. The Bridgestone Turanza tyres do a fine job but they lack the grip of a Michelin Pilot Sport. 

The lasting impression on the driver is a car that feels quick but doesn’t leave you wanting more. The best hot hatches make you want to keep on driving and driving, that’s not the case in the XPower.

As a daily driver it’s arguably better than its rivals, though, with quiet, effortless commuting potential thanks to its electric powertrain.

There’s the usual passive safety features, including six airbags as well as the required stability controls, anti-lock brakes and the like, however the XPower also comes equipped with the MG Pilot suite of active safety features as standard.

MG Pilot includes autonomous emergency braking, lane keeping assist, lane departure warning, adaptive cruise control, blind-spot monitoring and rear cross-traffic alert.

Thanks to all of this safety gear, the MG4 range was awarded a maximum five-star ANCAP assessment, when it was tested in 2022.

The 911 Carrera GTS is covered by a pretty underwhelming three-year, unlimited-kilometre warranty, with servicing required every 12 months or 15,000kms. We don’t have the hybrid service pricing yet, but as guide, the last 911 split the services into minor and major, and charged either $785 or $1285 for each.

Like every MG sold in Australia, the MG4 XPower is covered by the brand’s seven-year, unlimited kilometre warranty, which is industry standard for high-volume brands these days.

As for servicing, the intervals are also the same as the rest of the MG4 range, which means a lengthy two years or 40,000km, whichever comes first, between visits to the dealership.

That’s much longer than your typical petrol-powered hot hatch, which has more moving parts that need servicing. 

In terms of costs, the XPower is ever-so-slightly more expensive compared to the rest of the MG4 line-up.

A minor service is the same $296 but a major service (which comes every second service) will cost you $962.

But even so, for the first six years you’ll only be up for $1554 in servicing costs, which is comparatively cheap amongst its hot hatch rivals, and only $76 more than you’ll pay for any other MG4.
