Mercedes-Benz A200 vs BMW 320d

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.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel and meals provided.

Despite BMW's wholehearted embrace of the SUV its 3 Series is still a critically important model for the brand in Australia. And this new version certainly has the spec and tech to take the fight up to Merc's C-Class. And if you're in the happy position of making that choice, it's now a whole lot harder. For our money the 330i marks the sweet spot with extra performance, safety tech and standard features for only a fraction more than $3k over the 320d entry-point.

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.

At just over 4.7m nose-to-tail the new 3 Series has crept 76mm in overall length but that dimension is still more than 200mm shy of its next-size-up 5 Series sibling.

Changes to the exterior design are more evolutionary than revolutionary. You're never going to mistake this car for anything other than a BMW 3 Series.

But even if the face is familiar, aerodynamic efficiency is outstanding. BMW admits its claimed Cd of 0.23 was achieved with a base model running on 17-inch wheels (not offered here), but even if bigger rims knock a few fractions off that number it's still an amazing result for a conventional four door sedan.

Big contributors are a full width front spoiler, 'air curtains' managing flow around each corner of the nose, almost complete sealing of the largest areas underneath the car, and a functional rear diffuser section.

The signature kidney grille has grown and is delivered as a single piece, with active shutters incorporated to manage cooling air flow through to the engine. Twin adaptive LED headlights (standard on all models) feature a sharp notch on their lower edge, a big clue for new model spotters.

Broad, carefully managed surfaces characterise the bonnet and flanks of the car, with a distinct character line just above door handle height enhancing its confident stance.

The slightly smoked L-shaped LED tail-lights sit proud of the body, and 18-inch alloys are standard on the 320d, stepping up to 19s on the 330i.

The interior has been redesigned with revised controls and new materials, including slick 'aluminium teragon' finish on the console and dash in the M Sport.

As you can see in our interior images, it's been tidied up and simplified considerably, although it will still be instantly recognised by current BMW drivers.

Highlights are a 12.3-inch configurable digital 'Live Cockpit Professional' instrument display (lifted directly from the X5), a new 10.25-inch media touchscreen and a standard (larger) head-up display.

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.

A longer wheelbase (+41mm) has helped increase overall cabin space and rear room specifically.

There's plenty of storage provided with a large lidded box between the front seats as well as two large size cupholders in a recessed section in front of the gear shift (which can be closed off with a roll-top style cover).

The glove box is large and there are big bins in the doors with separate holders for full-size bottles.

Rear legroom is generous. At 183cm, sitting behind my own driving position, there was plenty of fresh air between knees and seatback, with lots of foot room to boot.

Headroom was more marginal with a straight back leading to a bonce/roof interface. But there are adjustable rear vents, twin cupholders in a fold-down centre armrest, and big bottle holders in the doors. Multiple USB ports (Type A and Type C) and a 12-volt power outlet are provided front and rear.

The boot space offers up a 480-litre luggage capacity with a 40/20/40 split-folding rear seat increasing cargo flexibility. Local towing capacity is yet to be confirmed, but indicative (European) ratings for both models are 750kg for an unbraked trailer and 1600kg braked.

Standard rubber is run-flat so there's no spare of any description.

Pricing for the two-model launch line-up starts at just under $67,900 before on-road costs for the 320d, rising to $70,990 for the 330i.

That means it remains head-to-head with comparable Merc C-Class models, and other premium mid-size competitors like the Audi A4, Jaguar XE and Lexus IS.

Given many previous Australia-bound 3 Series models have been built in South Africa it's fair to ask where is the BMW 3 Series built, and the answer this time around is Germany.

And the standard features list is long, including 'Adaptive LED headlights' (with 'High-Beam Assistant'), LED fog lights and tail-lights, electrically adjustable and heated exterior mirrors (with electric fold-in function), rain-sensing wipers, three-zone climate control, electrically-adjustable sports front seats (with memory function for driver and front passenger), wireless smartphone charging, 'Aluminium Tetragon' interior trim finishers, 12.3-inch 'BMW Live Cockpit Professional' digital instrument display, 'Navigation System Professional' with 10.25-inch digital touchscreen display also managing a 10-speaker, 205-watt sound system, including a 20GB hard drive and DAB+ digital radio. Apple CarPlay is included.

Also included are 'BMW TeleServices' taking in 'ConnectedDrive'(free use of vehicle apps via 'BMW Online'), real-time traffic info and 'Concierge Services'. The 'BMW Intelligent Personal Assistant' responds to a "Hey BMW' voice command with a range of hands-free functions like nav, calls and texts. We had mixed success in challenging this friendly PA.

The default M Sport trim includes 18-inch 'M Double-spoke' light alloy wheels, BMW Individual high-gloss 'Shadow Line' black treatment on the window frame and air breather surround, the 'M Aerodynamics package' (aero front and rear bumper trims, and side sills), Alcantara/Sensatec (vinyl) upholstery (black with contrast blue stitching), Anthracite BMW Individual headliner, and an M leather steering wheel (with multifunction buttons).

The no-cost 'Luxury Line' treatment swaps in 'Vernasca' leather seats, ash grey-brown interior wood trim, a sport leather steering wheel, the instrument panel trimmed in Sensatec and standard level sport seats for the driver and front passenger.

Step up to the 330i and you can add 19-inch alloys, 'Vernasca' leather upholstery, 'Comfort Access' (keyless entry to all doors), adaptive suspension, M Sport brakes, 'Driving Assistant Professional' (active cruise control with 'Stop&Go' function, front and rear cross-traffic warning, steering and lane control assist, lane keeping assistant with side collision warning, crossroads warning and 'Evasion Aid'), and 'Parking Assistant Plus' ('Parking Assistant' with 'Active Park Distance Control' rear, 'Reversing Assistant', 'Surround View', 'Panorama View', and '3D View').

In terms of colours, 'Alpine White' and black are no-cost, wihle metallic shades - 'Black Saphire', 'Melbourne Red', 'Glacier Silver', 'Mineral White', 'Mineral Grey', 'Mediterranean Blue', 'Sunset Orange', 'Velmont Bronze' (brown), and 'Portimao Blue' add $2000 (rrp). And the 'BMW Individual' metallic shade of 'Dravit Grey' adds $2350. 

Lots and lots of fruit without any change to the price. Clearly BMW is determined to bring the 3 Series back to prominence.

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.

The 320d is powered by a 2.0-litre four-cylinder twin-turbo-diesel, featuring common-rail direct-injection and variable inlet timing. It produces 140kW at 4000rpm and 400Nm between 1750-2500rpm.

The turbo's multi-stage design incorporates a small, high-pressure, fixed-vane turbocharger as well as a larger, low-pressure, variable-vane turbo to maximise response, performance and efficiency.

A 2.0-litre single turbo-petrol four-cylinder engine sits under the 330i's bonnet incorporating direct-injection, as well as variable valve and cam timing. Peak outputs are 190kW from 5000-6500rpm and 400Nm between 1550-4400rpm.

Mark the date because this is the first time the BMW 3 Series has been offered in Australia without a manual gearbox option. Both launch models send drive to the rear wheels via an eight-speed automatic (with wheel-mounted shift paddles) only.

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.

Despite each car's performance potential claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is commendably low.

BMW says the 320d delivers excellent diesel fuel economy, consuming a miserly 4.5L/100km, emitting 119g/km of CO2 in the process, with the 330i's fuel consumption figure coming in at 6.4L/100km and 147g/km.

You'll need minimum 95 RON premium unleaded in the 330i, with both petrol and diesel requiring 59 litres to fill the tank to full capacity.

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.

First, the performance figures. BMW claims the 320d will accelerate from 0-100km/h in 6.8sec, which is agreeably quick, while the 330i knocks that down to 5.8sec, which is properly fast.

Both engines deliver the same 400Nm of maximum torque at low rpm; 1750-2500rpm for the 320d, and a broader 1550-4400rpm spread for the 330i. Mid-range acceleration is strong and satisfyingly linear in each, the 330i that bit more urgent at the top end.

The eight-speed auto is velvety smooth, with the wheel-mounted shift paddles on hand for rapid 'manual' changes. Engine noise is muted at low revs but nice and rorty under pressure.

A stated aim in the development of this 3 Series was "dynamic engagement", and the standard strut front, multi-link rear suspension has been tuned to reinforce the driving part of the brand's long-standing 'ultimate driving machine' promise.

The standard suspension includes tricky two-stage dampers front and rear, but with all cars at the local launch fitted with the optional active damper system we'll have to wait to report on its quality (or otherwise).

This car's centre-of-gravity is 10mm lower than the model it replaces, which may not sound like much, but in engineering terms, absolutely is. In concert with a perfect 50:50 front-to-rear weight distribution, and wider tracks front and rear, it helps deliver an overall planted feel and predictable cornering balance.

The electro-mechanically assisted steering is accurate and linear with good road feel, which is not always the case in recent Beamers.

The launch fleet was also rolling on 19-inch rims (standard on 330i, optional on 320d) shod with Bridgestone Turanza run-flat rubber (225/40f - 255/35r) and despite that type of tyre's reputation for harsh characteristics and a moderate level of road noise, ride comfort on the typically coarse rural roads we covered in the Victorian high country was impressive.

Braking on both models is by ventilated disc front and rear, and even in spirited cornering maintained their power and efficiency. The M Sport brake package fitted to the 330i dials things up with four-piston alloy calipers (sourced from Brembo) up front.

The standard sports steering wheel is fat and grippy, the sports front seats combine firm location with long-distance comfort and overall noise levels are low. Overall, this is a super-impressive touring car.

The new 3's active safety package is exactly where it needs to be, with all the 'cost-of-entry' items like ASC, DSC, ABS, 'Braking Assist', and traction control included. But additional tech includes everything from all-speed AEB, 'Lane Departure Warning', 'Lane Change Warning', head-up display and 'Front Collision Warning' (with brake intervention), to 'Cornering Brake Control', 'Rear Cross-Traffic Warning', 'Rear Collision Prevention', 'Speed Limit Information', 'Parking Assist' (with 'Reversing Assistant') and 'Dynamic Braking Lights'.

Step up to the 330i and you can add 'Steering and Lane Control Assist', 'Emergency Stop Assistant', 'Auto Speed Limit Assist', 'Lane Keeping Assist', 'Front Cross-Traffic Warning', 'Evasion Aid', 'Crossroads Warning' (with 'City Braking' function), 'Wrong Way Warning', as well as 'Parking Assistant Plus' (with 'Surround View Camera' and 'Remote 3D View').

On the passive side, the airbag count runs to eight (front and side airbags for driver and front passenger, and head airbags for all four outer seats). 'Intelligent Emergency Call' is also included.

There three top tether anchors for child seats/baby restraints across the back seat, with ISOFIX anchors on the two outer positions.

This seventh-generation 3 Series is yet to be assessed by ANCAP or EuroNCAP, but it's a safe bet it will pick up a maximum five-star safety rating.  

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.

BMW offers a three year/unlimited km warranty, which is drifting off the pace now with the majority of mainstream brands stepping up to five-year cover, with some at seven.

On the upside, bodywork is covered for 12 years, the paint for three, and 24-hour roadside assistance is complimentary for three years.

Servicing is condition based, so the car tells you when maintenance is required, and BMW offers a range of service packages in 'Basic' and 'Plus' grades up to 10 years/200,000km.
