Mercedes-Benz A250 vs BYD Atto 2

What's the difference?

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 BYD Atto 2 isn't just the cheapest electric SUV in Australia, it's also one that doesn't feel all that cheap, which is a hell of a magic trick. If it's easy, comfortable city motoring you're after, the Atto 2 delivers in spades. But if your blood type is high octane, there are better driving EVs out there.

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.

I think it’s a sharp-looking thing, this Atto 2. Kudos to BYD for not making the design look like it’s trying too hard, or like the Atto 2 is something it isn’t. It’s just smooth, sensible small SUV with styling that looks like it will age gracefully.

I like the chunky black moulding which makes it look a bit tougher than it is, plus the LED DRLs and swept back (and spoiler-equipped) roofline add a bit of visual drama.

Inside, BYD has made two pretty good choices. The first is that the cabin feels toned down from the one in the Atto 3 (which is all chunky wheel-style controls and vents). 

This one feels far more sedate and conventional in its design, which I think is a win.

The other good decision is to equip the Atto 2 with soft plastics, rather than hard scratchy ones, in places like the door panels. In some cheaper cars, you feel your elbows constantly rubbing against cheap-feeling plastics, but that’s not the case here.

Too much stuff is still controlled through that central screen, and BYD has an awkward way of shortcutting functions. They call it a three-finger swipe, meaning that if you run three fingers across the screen horizontally you can adjust the climate-control’s fan speed, while swiping horizontally adjusts temp, but it feels like a weird movement.

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 Atto 2 measures 4310mm in length, 1830mm in width and 1675mm in height and it rides on a 2620mm wheelbase. It also sits on BYD’s fully-flat EV platform, which helps to maximise space in the back seat.

I’m 175cm tall and could get comfortable behind my own driving position, with enough knee and headroom to ensure I didn’t feel cramped.

There are two ISOFIX attachment points, one in each window seat in the back as well as USB-A and -C connection points.

Boot space is a not cavernous, but also not tiny, 380L with the rear seats in place, growing to 1320L with the rear pews folded flat. Both models also offer a V2L (Vehicle to Load) connection, too, so you can power up household devices.

This thing really is cheap. The BYD Atto 2 arrives with a two-model range kicking off with the Dynamic, at $31,990, before on-road costs, before stepping up to the Premium at $35,990 BOC. They both get the same motor and battery, by the way, so the extra money comes down to extra kit.

The Dynamic rides on 16-inch alloys wrapped in cheaper Westlake rubber, scores LED headlights and DRLs and gets rain-sensing wipers and heated wing mirrors. Inside, there’s a 10.1-inch central touchscreen, an 8.8-inch driver display, synthetic leather seats with manual adjustment up front and wireless Apple CarPlay and Android Auto linked to a four-speaker stereo.

The Premium rides on 17-inch alloys wearing better Hankook rubber, and there’s a panoramic glass roof with a shade and roof racks. Inside, the central screen grows to 12.8 inches, and there’s an eight-speaker stereo and a wireless charge pad. Your seats are now electronically adjusted and heated and cooled. Plus there’s some extra safety stuff, but we’ll cover that off in a second.

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.

Both Atto 2 models share the same powertrain - a front-mounted electric motor producing 130kW/290Nm which is sent to the front tyres. It feels fairly sedate, even under flat-footed acceleration, though BYD reckons you can knock off the sprint to 100km/h in 7.9 seconds.

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.

Both models also share the same battery, a 51.1kWh LFP unit, which should unlock a WLTP driving range of 345km. AC charging is pegged at 7.0kW, so a good match for a standard home wallbox, while DC fast charging is 82kW. Using the latter, BYD says you should go from 10 to 80 per cent charged in 38 minutes.

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.

Your drive experience in the Atto 2 very much depends on what you ask of it.

Or to put it another way, the first half of my drive route was a breezy run through the city and suburbs, then onto the freeway, before arriving at our destination. 

It was probably 60 kays or so, and across it all the Atto 2 felt quiet and comfortable, with enough power at its disposal to easily get up to speed and stay there. 

In the second half, though, I hunted down some twisting roads and cracks started to appear. The ride is pretty solid and there isn't huge amounts of body roll during more enthusiastic cornering. 

But the steering is vague and there's plenty of slack – you can turn the wheel a fair bit without eliciting much response from the tyres.

Interestingly, turning the wheel with a bit of aggression also produced a weird sound up front, like you could hear the mechanicals shifting the tyres.

The tyres make a difference, too, with the Premium's more expensive Hankook rubber far happier to hang on without squealing than the Dynamic's Westlake tyres. 

But context is key here. The Atto 2 is an accessible, affordable city-focused EV, and it performs those duties admirably. But if you're sold on a car-driver connection, there isn't much of that on offer here.

The Atto 2 is yet to be assessed by ANCAP but there’s no shortage of stuff. The entry-level car gets six airbags, rear parking sensors and all the usual traction tech. Then there’s active cruise, lane departure warning, blind spot monitoring, cross-traffic alert in both directions - the list goes on. In fact, the only things the Premium adds on top are a 360-degree camera and front parking sensors. 

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.

BYD’s warranty is an okay six years but just 150,000km, which is underwhelming compared to the best in the business. The battery is covered for eight years or 160,000km.

BYD vehicles typically have 12 month, 20,000km service intervals with capped price servicing, but the details are yet to be confirmed for the Atto 2.
