BMW 120i vs Mercedes-Benz A250

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 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 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.

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.

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.

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.

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 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.

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.

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.

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 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.

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.

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.
