BMW 120i vs MG MG4

What's the difference?

I’m the first to say the 1 Series is kind of the ugly duckling of the BMW family, but those looks grow on you, especially when you consider that this is exactly what a BMW hatch should look like. That this is one of the only rear-wheel-drive hatches left on the planet makes it even more special – and of course engaging to pilot. The downside is the price and the lack of value from a features perspective, plus safety could be bolstered with more technology. Still, anybody who likes to drive will commend you on your choice of a BMW.  

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.

The 1 Series looks exactly how a BMW hatchback should. I know that sounds silly but what I mean is BMW could easily have designed something that was proportioned more like other hatches; that popular sort of bubble on wheels.

Instead, what you have is a hatch that retains BMW’s traditional attributes – there’s the long nose, the cabin set back, the high sides and the wheels placed almost at the very corners.

Seriously, look at the image of the orange 1 Series side on, now hold your out your hand and use it to cover just the windows – see, it looks just like a BMW 2 Series convertible. Does it look good? To me it does, right up until you get to the hatchback, and then it looks a bit awkward. But I do admire BMW’s designers for creating something unique looking.

That orange 120i ('Sunset Orange' is the official colour) is the most recent 1 Series I’ve tested. Those wheels aren’t standard, they’re 18-inch M ones and they are part of the optional 'M Sport Package', which also includes the body kit, complete with side skirts and the lower grille in gloss black.

The 1 Series is as affordable as BMWs get, but it’s still a real BMW. The cabin, for example, looks much like  every BMW, only smaller.

There’s the large, slab-like dash with the display sitting atop, below are the air vents and below that is the radio and then the climate-control dials. It’s a stack that’s kept its familiar order and shape on nearly all BMWs for what seems like forever.

The centre console has a similar layout as the one in a 3 Series or 5 Series or any Series, with the shifter and rotating media controller. Even the doors have the same design as those cars higher up in the BMW family, with the big moulded pockets and large pull handles.

The cabin isn’t as ‘blingy’ as the new Mercedes-Benz A-Class, but it’s not as plain as the Audi A3.

That steering wheel is part of the M-Package too, but the leather upholstery is a separate option.

The signs that this isn’t a more expensive BMW are the manual handbrake, the compact instrument cluster with analogue dials, the small dash-top display and the fact that  there’s a lot less real estate to be covered by trim pieces and material, which doesn’t have the same high-quality feel as those fancier models.

The cabin isn’t as ‘blingy’ as the new Mercedes-Benz A-Class, but it’s not as plain as the cockpit of an Audi A3 – it’s somewhere in between; refined and well designed.

At 4.3m end to end, the 1 Series is 16mm shorter that the A3 Sportback and 20mm narrower, at just over 1.7m across.

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.

The 1 Series’ boot has a cargo capacity of 360 litres, which is more than the boot space of the Audi A3 Sportback (340 litres) but less than the new Mercedes-Benz A-Class’s 370 litres of luggage room.

What does that mean in real-world terms? It’s not a lot of space, and you might struggle to get a pram in, so check that  beforehand if you have small ones. That said, there was enough room for two carry-on sized bags, a computer bag and a scooter when my wife and I went on a weekend away with our four year old.

Space in the second row is also limited. Headroom isn’t too bad, but at 191cm tall I can’t sit behind my driving position without my knees digging into the seatback. I can just fit back there in the A3 and I have even more room for my knees in the A-Class.

Room up front is good with plenty of shoulder, head and elbow room for somebody my size.

Storage could be better: you’ll only find cup holders up front (two of them), the centre-console storage bin is small and so are the door pockets in the rear, but all is not lost because the door bottle holders in the front are massive, the glove box is a decent size and there are nets on the backs of the front seats.

It’s good to see directional air vents in the second row and a 12V power outlet, but there aren’t any USB ports back there – if you want to plug in a device there’s only one and it’s up front, along with another 12-volt outlet.

The rear doors appear large from the outside but the aperture to get in and out isn’t huge – again look at the images to see what I’m on about.

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.

As you step up through the grades the engines become more powerful. The entry-grade 118i has a 1.5-litre three-cylinder turbo-petrol making 100kW of power and 220Nm of torque, while its diesel twin has a 2.0-litre turbo-four making 110kW and much more torque at 320Nm.

The 120i has a 2.0-litre turbo-petrol four-cylinder and an output of 135kW and 270Nm. Then above that is the 125i, which is getting into performance territory with its 2.0-litre turbo four petrol making 165kW and 310Nm.

But all hail the M140i and its beautiful 3.0-litre six-cylinder turbo-petrol, with 250kW and 500Nm that it wants to share with you.

All cars are rear-wheel drive and all have an eight – hang on, that’s important: all cars are rear-wheel drive. Do you know how many other hatchbacks are rear-wheel drive? Try next to none – not the A-Class, not the A3, not the Golf. Rear-wheel drive is favoured for performance cars because it offers better balance and better acceleration thanks to the weight shift to the rear of the car. BMW has long claimed that RWD is one of the keys to its "sheer driving pleasure".

Now let me finish the sentence... all have an eight-speed automatic, and it’s a beauty – a little slow, but smoother for driving than a dual clutch, and way more fun than a CVT.

But wait, because there’s a manual gearbox, too. It’s a no-cost option and you can get it on any variant apart from the 125i.

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.

BMW says its most efficient petrol engine in the 1 Series range is the three-cylinder in the 118i, which uses just 5.2L/100km after a combination of urban and open roads.

The diesel unit in the 118d will use 4.2L/100km. Let that sink in for a moment – petrol engines are becoming so fuel efficient that they’re rivalling diesels, which have long been lauded for their frugality.

So don't just buy the diesel just because it’s more efficient, because you may never recoup the extra money you paid over the 118i.

Thirstier but still super-efficient is the 2.0-litre in the 120i. BMW’s claim is 5.9L/100km. During my week with the 120i I put 413km on the clock and used 15.57 litres doing so (measured at the pump), which comes to 7.7L/100km. The car’s computer said 7.8L/100km.

That’s great fuel economy, even if it is higher than the claimed figures. The 125i’s official fuel consumption is also 5.9L/100km.

It’s not surprising that the M140i, with its 3.0-litre six-cylinder turbo-petrol engine, is the least fuel efficient but its official figure of 7.1L/100km is still low.

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!

If I could run into a showroom and take whichever 1 Series I wanted it’d be the M140i – and not just because it would give me the best chance of outrunning the police after they discovered the break-in, but because the thing is so much fun to drive.

It’s also the most expensive, of course, but it’s worth it for that screaming straight six and for its agility.

You’ll have fun, though, in every grade of the line-up – they’re all engaging to pilot with great driving positions, good pedal feel and that eight-speed auto is smooth in traffic yet will shift hard when you have your race face on.

You might find the 118i, with its three-cylinder, a little under powered, especially with five people and their bags on board. If you’re keen on this grade, then consider the diesel, which will give you more torque. Our 120i test car proved to have enough oomph for overtaking and moving quickly when needed.

The 125i is less tame, with its throatier exhaust note, firmer ride and better handling thanks to the M suspension.

If you plan on choosing the M Sport Package for, say, the 120i keep in mind that you’ll lose the comfortable ride these cars have on their standard tyres.

Our 120i had the pack and while the body kit looks tough, the 18-inch alloy wheels shod in low-profile rubber (225/40 R18 Bridgestone Potenza 5001s front and 245/35 R18 at the rear) meant the ride was overly jarring on bad roads.

Given that Sydney was my test bed for the 120i and its roads are shocking, the ride was less than comfy. The M-sport suspension will only make the ride less comfortable, but in return you’ll have a 120i with better handling.

Run-flat tyres are common on BMWs and you may have heard of a few issues surrounding noise and a harsher ride. While that can be true, it's the price you pay for having a tyre you won’t immediately have to change if you get a puncture. Only the 120i and the M140i don’t have run-flats as standard.

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 1 Series is covered by BMW’s three-year/unlimited kilometre warranty. Servicing is condition-based – the car will let you know when it needs a check-up.

BMW offers two service packages, which cover the car for five years/80,000km: the Basic is $1340 and the Plus costs $3550.

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.
