MG Mg7 vs Mercedes-Benz A250

What's the difference?

In a world obsessed with SUVs and electric powertrains, a mid-size petrol sedan almost feels rebellious. But the MG7 kind of is. A sleek fastback with a turbocharged engine, a sporty edge and a price that makes you look twice - it’s a compelling combination. There are some drawbacks for families in efficiency and back-seat practicality but it's not a bad offering for those wanting something a bit more fun than an SUV.

The A 250 e is a really interesting option in an evolving electrified landscape.

Not only is it a demonstration Mercedes is going to have a real go at plug-in hybrid cars in Australia, it also offers those who may be curious about an electrified vehicle a way of experiencing it on their terms.

The compromises are clear-cut, though. You can drive the A 250 e in any way you're comfortable with, but it's never going to be quite as good as a purpose-built EV, hybrid, or combustion car.

The MG7 is genuinely good looking. The fastback roofline gives it a sleek silhouette, and there’s a confidence to the way it carries itself.

The blacked-out badging, quad exhaust outlets, 19-inch Michelin tyres and red brake calipers all lean into that sporty brief. It looks fast standing still. The frameless doors are a nice touch, and the retractable rear spoiler adds a bit of theatre and fun.

Inside, the cabin follows through on that upmarket intent. Deep burgundy leather and synthetic suede are used generously throughout, giving it a sumptuous feel. Although, my husband joked that he wouldn't be able to drive it during State of Origin... sorry, Queenslanders!

There’s less reliance on piano black trim, which I appreciate as it scuffs easily, and most surfaces look well-finished. The integrated headrests up front give the illusion of proper sports seats but I do wonder if the interior would pop half as well if it was finished in the optional black.

The dashboard is dominated by a wide digital display incorporating a 10.25-inch instrument cluster and a 12.3-inch media screen. The panoramic sunroof helps keep things light and airy, and while there aren’t many physical buttons or dials, which is usually a gripe of mine, the overall execution feels cohesive and premium for the price point.

Similar to its GLC 300 e bigger sibling, you'd be hard-pressed to tell the A 250 e is a PHEV at all. There's very little about it which screams ‘eco' until you look a little closer. Only keen Mercedes enthusiasts will pick the eco-look wheels, with the only other two give aways being the lack of an exhaust and fuel flaps on both sides.

Other than those items, the A 250 e's exterior is the normal A-Class fare of slick but conservative Mercedes styling, gently accented with elements of chrome and black.

Inside is the same deal. It has all the same elements which make Mercedes' small car range unique and flashy to be behind the wheel of.

Our car had a controversial contrasting crème interior, but I have to say I much prefer the piano black trim items to the in-your-face chrome ones which usually come in these Benz small cars.

Obviously, there's a healthy options list to help you customise it further, but I'm a fan of the soft dash elements, and how the ‘Artico' trim is generously placed throughout to remind you this is a premium badged car.

I do like how Mercedes stands out from the crowd when it comes to its signature vent layout, dual-screens and everything from the lavish front seats to the wheel.

I especially like the blue colour our hatch came in, as you usually only see Benz cars in white, grey, silver, or black. Buy colours!

The 'MBUX' multimedia suite is also lightening fast and very customisable when it comes to its layout and look. I'd say its one of the best suites on the market, although interacting with it via the touch elements on the wheel and centre pad can be a bit fiddly.

Up front is where the MG7 feels most generous. The electrically adjustable front seats are comfortable and supportive for daily driving, although extendable under-thigh support would help reduce fatigue on longer trips. You do get heating for both the seats and the steering wheel but having to dive into the media menu to activate them is annoying.

In the second row, legroom is respectable for a mid-size sedan. Headroom, however, is tighter thanks to the fastback roofline and panoramic sunroof. Tall teenagers won't feel like they can sprawl out but younger kids will be fine. The second row features two ISOFIX child seat mounts and three top-tether anchor points but two child seats will fit best. Bending down to buckle in a child will remind your back why SUVs became all the rage, but it's certainly doable.

The seats in the second row are thickly padded and comfortable, and the fold-down armrest sits at a good height to lean on. Amenities aren’t especially extensive given there’s only one grade available, but you do get a couple of cupholders, map pockets, directional air vents and two USB-C ports.

Storage in the front row is about what you’d expect for a car of this size. There’s a decent glove box, a shallow middle console, large door bins and some handy little nooks near your knee. A sunglasses holder and a dedicated phone cradle with wireless charging round things out nicely. The wireless charger can lag a little in topping up your battery, and it's quick to overheat your phone - added ventilation would be a big help here. However, there’s also a 12-volt socket and two USB-C ports if you prefer a cable.

The media system itself is responsive and largely intuitive, although the touchpad-style controls on the dash feel slightly back-to-front in use. On the plus side, it’s very easy to flick into Sport mode and open up the exhaust using the cluster controls, which adds a bit of fun to the daily drive.

The boot offers 375 litres of capacity, which is on the smaller side for the segment. Comparatively, the Sonata N Line offers 480L, the Skoda Sportline 600L and the Camry 524L. That said, it’s been perfectly usable for grocery runs and the odd road trip this week. You do need to load bulkier items further back toward the seats to work around the sloping fastback design. A powered tailgate adds convenience, and there’s a temporary spare tyre underneath, which I always prefer to a repair kit.

Like all A-Class hatchbacks, this Benz is centred pretty much solely around the front two passengers. Both get lavish seat trims and lovely touchpoints, easily a cut above mass market rivals. 

Space perhaps isn't this car's forte, with the A- and B-pillars cascading inwards for a low roofline and a comfortable but not spacious interior width. 

Raised console elements and elbow resting points add to the primo feel, but visibility is limited from the tiny wing mirrors and small rear window.

Front passengers get some large binnacles in the door trims, cupholders in the front, a decently sized centre console box housing two USB ports, a surprisingly large glove box, and a shallow bay for wireless phone charging up front.

All three USB ports available to front passengers are USB-C type so you'll also need to be ready with some adapters.

Rear passengers get the same lovely sculpted seat trims, but it is limited back there for someone my 182cm (6'0") height and the large front passenger seats, low roofline, and smallish window apertures make for a tight-feeling space. 

There are nettings on the back of the front seats, small binnacles in the doors and a tiny shelf on the back of the centre console.

There are no amenities like adjustable air vents or charging ports for rear passengers, although the two USB-C jacks located in the centre console box should be within reach.

Boot space is an interesting story. Mercedes has packaged the electric elements in this car to consume the least amount of space possible. So, despite a relatively large and water-cooed lithium-ion battery under the boot floor, and 35-litre fuel tank in front of the rear axle, the hatchback as tested here only loses 45-litres compared to its non-hybrid version. No mean feat.

This makes total space available a decent 310 litres (VDA). You'll get a little more in the sedan version of this car, and it is larger than the Audi A3 40 TFSI e which offers 280L.

The A 250 e is not wildly expensive when you consider its plug-in hybrid credentials and premium market position, but then, $63,400 (MSRP) is asking a lot for any non-performance hatchback this size.

Value is also lost in the fact there's no all-wheel drive like the A 250  4Matic which sits below it in the A-Class range. This car isn't quite the same value proposition as its larger plug-in GLC 300 e sibling.

At least in terms of interior features and multimedia this car feels as premium as it is priced. Interior features include ‘Artico' faux-leather seats, premium soft-touch materials throughout the cabin, and Benz's now signature dual 10.25-inch screens it uses for a fully digital dash cluster and multimedia screen.

This car has Apple CarPlay and Android Auto connectivity, voice recognition and controls, built-in nav with live traffic and the ability to search for nearby charging points, and it also gets LED headlights and some unique 18-inch alloy wheels to sweeten the deal.

To read about how different this car is under the skin from a regular A-Class hatch when it comes to drivetrain, check out the ‘engine and transmission' part of this review, and there are also some caveats when it comes to this car's safety suite, so check that section out, too.

The biggest challenge for the A 250 e will be in the fact there are a lot of compelling rivals. A Corolla hybrid, for instance, can offer similar efficiency gains, depending on how you drive it, and a much lower ownership cost for half the upfront price.

The A 250 e is a bit of a step beyond in terms of electrification and we fully understand many buyers will be willing to take the plunge just because it's a Mercedes product. However, there is a compelling direct rival on the way in the form of the Audi A3 40 TFSI e. Watch this space.

The MG7 has a 2.0L, four-cylinder turbo-petrol engine producing up to 170kW of power and 380Nm of torque. That’s pretty gusty compared to its nearest rivals, although the Sonata N Line still beats it with its 213kW/422Nm outputs. The Hyundai is more of a dedicated sports model. Still, with these outputs the MG7 manages a 0 -100km/h sprint in a swift 6.5-seconds!

Power is delivered to the front wheels and the nine-speed auto transmission punches through its gears relatively smoothly. You can also flip it into Sport mode, where gear changes become more pronounced.

Overall, the whole setup creates an engaging on-road experience without lulling you into any false pretences. The MG7 is not a racer, even though it looks like one, but it holds its own.

This is where most of your money goes. Up front, the A 250 e gets a familiar 1.3-litre four-cylinder petrol engine, used elsewhere in Mercedes range.

This engine produces 118kW/250Nm and drives the front-wheels via an eight-speed dual-clutch automatic transmission.

This transmission also houses the electric motor, which is powerful for a hybrid this size, offering 75kW/300Nm for a healthy amount of cruising power without engine assistance.

These two combine for a massive output of 160kW/450Nm, with the electric motor and petrol engine working in tandem under heavy acceleration for a 0-100km/h sprint time of 6.6 seconds.

The A 250 e houses a 15.6kWh water-cooled lithium-ion battery under the boot floor to power said motor. This is, again, large for a hybrid this size, and grants an electric-only range of 73 kilometres (ADR) despite weighing in at just 150kg.

As the battery and fuel tank have moved in the way of where the exhaust port normally is, Mercedes has placed the entire exhaust system in the transmission tunnel which normally houses the 4Matic all-wheel drive system on the A 250 variant. Interesting stuff.

The MG7 has a claimed combined fuel consumption figure of 8.0L/100km. With its 65-litre fuel tank, that equates to a theoretical driving range of up to 812km.

That places it broadly in line with the Hyundai Sonata N Line, which claims 8.1L/100km, although the Hyundai delivers stronger engine outputs. The Skoda Octavia Sportline is notably more frugal at 6.1L/100km, while the Toyota Camry SL continues to dominate the efficiency conversation with its 4.0L/100km hybrid figure.

In real-world driving, expect that 8.0L/100km claim to creep up. Even after a week consisting mostly of longer highway stretches, my trip computer was sitting at 8.6L/100km. That’s not wildly unexpected for a turbo-petrol engine, and it’s hardly alarming, but efficiency is a major consideration for families. Against hybrid rivals, it doesn’t win that particular argument.

Combined CO2 (ADR 81/02) emissions sit at 183g/km, which is comparative to the Hyundai Sonata N Line but not as low as its other rivals.

MG recommends a minimum 95 RON unleaded petrol to be used.

All this jiggery-pokery makes for all sorts of very impressive fuel consumption numbers. This car's official one is just 1.6L/100km, although this is going to vary wildly by how you drive it (more on this in the driving section).

Fuel consumption is just one element of this car's drivetrain though. You'll also need to consider energy consumption which is officially rated at 14.8kWh/100km.

You can think of these two consumption elements as a sliding scale. The more you can use the electric motor and regeneration features, the lower your fuel consumption will be, conversely if you drive under primarily petrol or hybrid power, you'll be able to lower your energy consumption.

Read the driving section for more on how this particular car gives you unprecedented control over this.

We had the A 250 e for just three days and managed to cover roughly 250km, I was thoroughly testing each drive mode as much as possible, and my final consumption figures came out 6.9L/100km of fuel consumption, and 5.9Kwh/100km of energy consumption.

If I had more time to charge, it was evident these numbers would have been altered drastically. Hopefully we'll be able to bring you a longer and more comprehensive Urban Guide test of this vehicle in the future.

Somehow, there is still more to the story, with this Mercedes offering a fascinating option pack which makes it even more flexible when it comes to charging.

The DC charging pack comes in at $1490 and lets you charge not just at regular public Type 2 ports, but also at ultra-fast DC locations. It also doubles the amount of power this car can pull from public outlets or a wallbox.

Keep in mind this car only comes with a regular wall socket to Type2 charger. This means to make use of fast charging at home (up to 7.2kW) you'll need to add the Mercedes-Benz Wallbox ($1200 not including installation by JetCharge) and to make the most of it when you're out and about (or if you don't have a garage) you'll need the public (Type2 to Type2) charging cable ($565.16).

See below for Mercedes' estimate of charging time for each of the charging options.

The A 250 e has a 35-litre fuel tank and a thirst for mid-grade 95 RON unleaded petrol. Oh, and if it's emissions you're conscious of, the A 250 e officially emits just 34g/km of CO2, far lower than the roughly 140g/km industry targets.

Power delivery in the MG7 is smooth and responsive, and it doesn’t take long to feel confident with the turbo-petrol engine. For a bit of extra fun, flick it into Sport mode and open the exhaust; gear changes become more pronounced, and the engine note gets noticeably throatier. It’s not a performance sedan, but it’s definitely engaging on the road.

Handling is another highlight. The steering is responsive and firms up depending on your selected drive mode, and the low-slung stance helps the car feel surprisingly nimble in corners. That said, it’s not always surefooted when accelerating out of tight bends, which reminds you that the MG7 is sporty but not track-focused.

Visibility is adequate but not perfect. The thicker pillars, lower roofline, and relatively small windows do make the cabin feel a touch enclosed, and there’s some road noise, which is enough to remind you it’s not a luxury saloon, but it never becomes intrusive.

The MG7 feels agile in tighter spaces, and the 360-degree camera system is high-quality. Parking is straightforward, which frazzled parents will appreciate.

The A 250 e is as interesting behind the wheel as it is on paper. To really explore it though, you'll need to delve into its complex drive modes.

It's more than just your usual comfort, eco, and sport. Each mode transforms the way you'll think about and drive this car.

The default is comfort, where the A 250 e behaves like you might expect from a plug-in. This means it will prefer to use electric drive unless you push the accelerator very hard. It makes for smooth and quiet motoring, although you'll find it chews through the electric range quite quickly, especially if you venture to the open road.

Sport mode prefers instead to primarily rely on the 1.3-litre four-cylinder engine. It's notably less refined, with this engine having a loud, gruff tone, and the introduction of vibrations and jerkiness from the dual-clutch automatic becomes immediately apparent.

It also firms up the steering, changes the transmission characteristics, and offers faster engine response from the accelerator pedal. As a side note, sport mode becomes a good tool for charging the battery quickly when you don't have access to a charging port.

The more interesting modes are electric, eco, and battery level. Battery level attempts to maintain the level the battery is currently at, while still using the car's hybrid features. This is so you can save the lion's share of charge for when it's most useful, like trawling in traffic.

Electric does what it says on the tin. Operates the car as an EV, not using its combustion engine at all. It also changes the car's paddle shifters from operating the transmission to altering the regenerative braking.

It offers modes varying from D+ which uses electric drive but coasts like a combustion car, to D-- which makes the car drive like a ‘single pedal' vehicle. This means it ups the regen braking to the point where the car will come to a full stop as you let your foot off the accelerator. It's the most efficient electric motoring mode.

Finally, eco mode lets you drive the A 250 e more like a conventional hybrid, limiting the electric motor to just taking off and cruising, preferring to switch to combustion more rapidly on acceleration.

While this car offers you unparalleled choice when it comes to electric motoring, it's worth noting it comes with its fair share of compromise.

This is far from the most refined car to drive in combustion mode, and it lacks the polish of, say, a Toyota hybrid when operating as a more traditional hybrid car.

I find it particularly interesting this car's best traits are found when it's operating as a purely electric vehicle. It's quieter, more refined, and the overpowered electric motor helps it feel just as good as a pure EV in terms of acceleration.

This car's downfalls as a combustion vehicle will be a real challenge for it. Again, it's a trade-off. The A 250 e doesn't feeel any heavier or more cumbersome than a 'normal' A-Class despite the extra battery size. But the ride is a bit harsh, and the dual-clutch leaves a lot to be desired in terms of refinement.

Asking more than $60 grand still seems tall when it's not as slick as a VW combustion car, and not as polished as a Toyota hybrid, either of which are half the price.

The A 250 e comes with the standard compliment of A-Class safety features, but there's one big-ticket item missing

On the active front the A 250 e scores auto emergency braking (freeway speed detects pedestrians and cyclists), blind spot monitoring, lane keep assist with lane departure warning, active high-beam assist, and traffic sign assist.

Notably, the excellent adaptive cruise suite which appears elsewhere in Benz's range is missing. The brand tells us this is because the A 250 e does not have the higher-end radar or 3D camera suite available elsewhere in the range.

The A 250 e also has an impressive complement of nine airbags as well as the usual stability, brake, and traction controls. Petrol variants of the A-Class were awarded a maximum five-star ANCAP safety rating in August 2018 scoring well across all categories.

MG backs the MG7 with a seven-year, unlimited-kilometre warranty. If you service exclusively through MG service centres, that coverage can be extended to 10 years or up to 250,000km, which makes it one of the more generous warranty offerings currently available.

At the time of this review, servicing intervals and service prices haven't been set for the MG7. It's fairly easy to secure servicing for an MG, as they have around 90 service centres nationwide at the moment.

Mercedes has caught up with most of the mainstream pack, now offering a five-year and unlimited kilometre warranty across its whole passenger car range. It's ahead of many of its rivals in the luxury segment, but matched by Korean newcomer, Genesis.

The A 250 e needs to be serviced once a year or every 25,000km, and pricing is no different from a non-electrified A 250. Pre-packaged service pricing for three years is $2050, four years is $2950, and five years is $3500.

Not ‘cheap' in the grander scheme, but there's no downside for picking this particular variant despite all of its extra equipment.
