Mercedes-Benz A180 vs BYD Atto 2

What's the difference?

Mercedes-Benz knows its way around a sedan, and this A-Class is a well-equipped, comfortable and efficient city-sized four-door.

But more than that, to my eyes anyway, it’s a perfect example of restrained form matching aero function with beautiful results.

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.

A global carmaker can’t hold its head up in public without a formal design strategy, and Mercedes-Benz uses ‘Sensual Purity’ as a guiding principle in developing the look and feel of its current models. It may sound airy-fairy, but I for one reckon it’s accurate in describing the A-Class sedan.

The overall form is flowing and minimalist, the major exception being a hard character line running down the side of the car from the trailing edge of the angular LED headlights and along the top of the doors to link with the tail-lights.

A rear-biased glasshouse emphasises the length of the bonnet, at the same time delivering a broad, muscular stance with short overhangs front and rear.

Ultra-fine panel gaps, careful sealing around the headlights and curved strakes either side of the bonnet keep the look clean and simple, not to mention super-slippery.

The interior has been styled to within an inch of its life, the dash dominated by the slick twin 10.25-inch widescreen ‘MBUX’ display covering instruments, ventilation, media and vehicle settings.

Five signature, turbine-style air vents (three in the centre, and one at each edge) lift the dash’s visual interest, and the quality of fit and finish is top-shelf.

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.

At a bit over 4.5m long, a fraction under 1.8m wide, and close to 1.5m tall the A-Class sedan is 130mm longer and 6.0mm higher than the hatch version.

The A-Class sedan driver is presented with the same sleek widescreen display as found in the hatch, and storage runs to two cupholders in the centre console, a lidded bin/armrest between the seats (including twin USB ports), decent door pockets with room for bottles and a medium-size glove box.

In a swap to the rear, sitting behind the driver’s seat set to my (183cm) position, I enjoyed adequate knee and headroom, although stretching up a to a straight-back position led to a scalp to headlining interface.

In the A 200 a centre fold-down armrest incorporates two cupholders, again there are generous pockets in the doors with room for bottles, and adjustable ventilation outlets are set into the back of the front centre console. Always a plus.

There are three belted positions across the rear, but the adults using them for anything other than short journeys will have to be good friends and flexible. Best for two grown-ups, and three kids will be fine.

One snag is the size of the rear door aperture. Okay for taller people on the way in, but a limb-unfolding gymnastic exercise on exit.

But of course the reason we’re all here is the boot, and the sedan’s extra length translates to an additional 60 litres of luggage space for a total cargo volume of 430 litres (VDA).

Extra space is one thing, but usability is another. The benefit of a hatch is a large opening that allows bulky stuff to find a home, and Merc has pushed the sedan’s boot aperture to just under a metre across and there’s half a metre between the base of the rear window and the lower edge of the boot lid.

That’s made a big difference and access is good, with the rear seats folding 40/20/40 to add extra flexibility and volume. There are also tie-down hooks at each corner of the floor (a luggage net is included) and a netted pocket behind the passenger side wheel tub (with 12-volt outlet).

At the time of writing Mercedes-Benz wasn’t quoting towing specifications, and don’t bother looking for a spare wheel, the tyres are run-flats.

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.

Both models are powered by the same 1.3-litre (M282) direct-injection four-cylinder turbo-petrol engine as the hatch, the A180 tuned to deliver 100kW (at 5500rpm) and 200Nm (at 1460rpm), with the A 200 bumping that up to 120kW (at 5500rpm) and 250Nm (at 1620rpm).

Drive goes to the front wheels only via a seven-speed dual-clutch automatic transmission.

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.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 5.7L/100km for both models, with a CO2 emissions figure of 130g/km.

Over roughly 250km of open highway driving on the launch program the A 200’s on-board computer coughed up a figure of 6.3L/100km. So, the real-world highway cycle figure is higher than the claimed combined number. Which is a miss, but not a massive one, and fuel-efficiency is still pretty impressive.

Minimum fuel requirement is 95 RON premium unleaded, and you’ll need 43 litres of it (plus a 5.0-litre reserve) to fill the tank.

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.

Three things stand out on first meeting with the A-Class sedan – ride comfort, steering feel, and road noise, or rather the lack of it.

The ‘biggest’ compliment you can pay a small car is that it rides like a bigger one, and behind the A 200’s wheel you’d swear the wheelbase was appreciably longer than the 2.7 metres it actually measures.

Over long undulations, even higher frequency bumps and ruts, the A-Class remains stable and composed thanks to a thoroughly sorted (strut front, torsion beam rear) suspension, with beautifully progressive damping a particular highlight.

Electromechanically-assisted steering points accurately and delivers good road feel without any undue vibration. And despite the A-Class launch drive loop covering typically coarse-chip bitumen roads through rural Victoria, overall noise levels remained impressively low.

Acceleration is brisk rather than properly sharp, but in the A 200 there’s more than enough oomph to keep things on the boil for easy highway cruising and overtaking.

With maximum torque available from just above 1600rpm, and a seven-speed dual-clutch auto transmission keeping revs in the sweet spot, the A 200 breezes through the cut and thrust of city traffic, too.

Auto shifts are smooth and quick, with manual changes via the wheel-mounted paddles adding even more direct access to your ratio of choice. And the bonus is no sign of the slow-speed shuntiness sometimes exhibited by dual-clutch autos, especially in twisting, three-point parking manoeuvres.

Special call-out for the cruise control which responds to adjustments quickly (including 10km/h jumps up or down with a firm press of the thumb) and rapidly retards downhill speeds.

Several unbroken hours in the front seat couldn’t generate a twinge of discomfort, the brakes are strong, and over-shoulder visibility is marginally better than in the hatch (not that it’s a weakness in the latter).

Add the sleek and intuitive multimedia system, high-quality audio, plus excellent ergonomics and you have a neatly resolved compact sedan that’s easy to use in the city and suburbs, keeping solid road-tripping ability up its sleeve as well.

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-Benz covers its passenger car range with a three year/unlimited km warranty, like the other two members of the German ‘Big Three’ (Audi and BMW) .

That lags behind the mainstream market where the majority of players are now at five years/unlimited km, with some at seven years.

On the upside, Mercedes-Benz Road Care assistance is included in the deal for three years.

Service is scheduled for 12 months/25,000km (whichever comes first) with pricing available on an ‘Up-front’ or ‘Pay-as-you-go’ basis.

Pre-payment delivers a $500 saving with the first three A-Class services set at a total of $2050, compared to $2550 PAYG. Fourth and fifth services are also available for pre-purchase.

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.
