BMW 320d vs Mercedes-Benz CLA200

What's the difference?

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.

The Mercedes-Benz CLA 200 is sleek, well-equipped, and beautifully engineered. That said, it’s pricey. You can get a car that’s 80 percent as good for 50 per cent of the price. But getting that extra 20 percent in terms of refinement, dynamic ability and design sophistication is what you’re paying for. If you’ve got the extra dough, top dollar buys you a spot on the top shelf.

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

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.

While the way a car looks is a subjective call, and as always, your thoughts are welcome in the comments below, I’m putting it out there… this is a beautiful machine. And Gordon Wagener’s not pulling any punches, either. He thinks it has the potential to become, “a modern design icon.”

The long bonnet, cab-rear, wide-track proportions sit within a slightly larger footprint. The new CLA is marginally longer, wider, lower overall, and has a lengthier wheelbase than the model it replaces. And the car’s intricate mix of gently curved surfaces and hard lines is expertly managed, with a standard AMG body kit, complete with 18-inch rims, adding just a hint of macho intent.

The angle of the shoulder runs from this character line, virtually unchanged up to the roof, and the inward slope of the side glass (car designers call it tumblehome) is quite pronounced. And the sweeping curve at the top of the front guards is defined by hard strakes on the outer edges of the bonnet.

The rear view is arguably the CLA’s most appealing angle with the intersection of the sloping turret, boot, and rear guards neatly resolved.

It’s super slick aerodynamically, as well, boasting a Cd of 0.23, running a close second to it’s A-Class sedan sibling (0.22) which Merc claims as the world’s most aero-efficient series production four-door.

But what about the inside? Well, the biggest visual feature is the customisable MBUX media and data interface, expressed dramatically through a pair of 10.25-inch widescreens.

The info available and number of configurations offered is mind-blowing. It’s very 2019 and spot-on target for the digital generation.

Piano black surfaces around the dash and console lift the tone (but pick up the fingerprints) while the signature turbine-style vents add another flash of visual interest without compromising function.

Other highlights include front seats with racy one-piece backs (reflected on the top of the outer rear seats, as well), frameless doors enhancing the coupe feel, and neatly detailed stitching around the dash and doors.

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.

Despite a two mm drop in overall height, the CLA’s front headroom has been extended by 17mm, and there’s lots of room up front, with storage running to two cupholders in the centre console, a lidded bin/armrest between the seats (including twin USB ports), an overhead sunglass holder, decent door pockets with room for bottles and a medium-size glove box.

There’s also a mat for wireless device charging at the front of the centre console, complete with another USB input (just in case).

But what does that sexy, sloping roofline do for space in the rear?

Sitting behind the driver's seat set to my (183cm) position, there’s adequate legroom, but despite Merc claiming an extra 3.0mm of headroom, my noggin made firm contact with the headliner.

It’s worth remembering this is a coupe-style four-door, with the packaging compromises a swoopy roof brings. You could call it a ‘2+3’, with a couple of doors added to make access to the back seats easier.

A centre fold-down armrest incorporates two cupholders, again there are generous pockets in the doors with room for bottles, map pockets on the front seatbacks, and adjustable ventilation outlets set into the back of the front centre console are a welcome inclusion.

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. Kids will be fine.

Boot volume is a healthy 460 litres (VDA), which is down 10 litres on the first-gen car, but the aperture has been widened by no less than 262mm, and a 40/20/40 split-folding rear seat opens up extra space. There are tie-down hooks, a 12-volt outlet and elasticised storage pockets either side of the load space to further enhance useability, plus a cargo net is included.

No news on towing capacity at this stage, and don’t bother looking for a spare, the tyres are run flats.

In Australia the CLA 200 weighs in at $59,500, before on-road costs, which is plenty, but the all-wheel drive CLA 250 ($68,800) will join it early in 2020, so the range will line up against the likes of BMW’s 4 Series Gran Coupe, even the Audi A5 Sportback.

The Mercedes-AMG CLA 35 ($83,400) arrives before the of 2019, with the full-fat CLA 45 S scheduled for Q1 2020 (estimated circa $95,000).

For that $60K price tag the CLA 200’s standard features list includes, dual-zone climate control air, sports seats, ambient (interior) lighting, ‘Artico’ and ‘Dinamica’ trim (faux leather and suede, respectively), the twin 10.25-inch digital media and instrument screens (running the ‘MBUX’ interface), an AMG styling pack (including 18-inch alloy wheels), active cruise control, auto headlights, keyless entry and start, LED headlights, DRLs and tail-lights, a leather multi-function, flat-bottom sports steering wheel, sat nav, park assist (including a reversing camera), rain-sensing wipers, wireless phone charging, ‘Hey Mercedes’ voice control, and nine-speaker audio including digital radio as well as Apple CarPlay and Android Auto.

All CLAs can also be hooked up (via a smartphone app) to the ‘Mercedes me Connect’ remote connectivity system, allowing access to locking/unlocking the doors, tracking and locating the vehicle, retrieving maintenance and service information, and more.

For the record, our test example was loaded with five option packages, adding no less than $13,630 to the price tag for a total of $73,130. Specifically, the ‘AMG Exclusive Package’ ($3190) – Heated and cooled front seats, ‘Lugano’ two-tone leather upholstery (with contrast top-stitching), adaptive damping, and ‘Energising Comfort Control’, the ‘Communications Package’ ($2490) - Head-up display and  Burmester 590W, 12-speaker ‘surround sound’ audio, ‘Driver Assistance Package’ ($1790) – ‘Active Distance Assist’ (including ‘Cross-Traffic Assist’), ‘Driving Assistance package Plus’, ‘Lane Change Assist’, ‘Extended automatic Re-start’ (in traffic), and ‘Route Based Speed Adaptation’, and ‘Seat Comfort Package’ ($1290) - Electrically adjustable front seats, memory function for driver’s seat, exterior mirrors and head-up display (if fitted), heated front seats, and passenger mirror with reverse parking position, and ‘Vision Package’ ($2490) – ‘Adaptive Highbeam Assist PLUS’, ‘Multibeam’ LED headlights, panoramic electric sunroof, ‘Parking package HIGH’ (featuring 360-degree camera).

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.

The CLA 200 is powered by Merc’s 1.3-litre (M 282), direct-injection four-cylinder turbo-petrol engine driving the front wheels through a seven-speed dual-clutch auto transmission (with paddle shifters on the wheel).

It’s the product of a joint development with Renault, and outputs are 120kW at 5500rpm and 250Nm at 1620rpm, which is pretty impressive for such a small capacity unit.

The single turbo features an electronically controlled wastegate and flexible charge pressure control to optimise boost across the entire rev range (rev ceiling is 6300rpm), with an equal focus on power, step-off throttle response and fuel efficiency.

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.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 5.7L/100km, the CLA emitting 130g/km of CO2 in the process.

At just over 1.4 tonnes it’s fairly hefty for its size, but at partial load between 1250-3800rpm two of the engine’s four cylinders shut down to improve economy. ‘ECO’ mode dampens performance in the name of improved economy, plus stop-start is standard.

And over roughly 200km of freeway, city and suburban running we saw an average of 7.5L/100km courtesy of the on-board read-out.

Minimum fuel requirement is 95 RON premium unleaded, and you’ll need 43 litres of it to fill the tank, which at our real-world average delivers a range of approximately 575km.

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.

So, despite the engine’s small capacity the addition of a turbo means peak torque (250Nm) arrives at just 1620rpm. Power delivery is linear and mid-range acceleration is healthy. Claimed 0-100km/h acceleration is 8.2sec, which is neither sluggish nor particularly fast, but performance is more than adequate around town and on the highway.

The seven-speed dual-clutch auto shifts smoothly, but not particularly rapidly, although a switch to manual mode and use of the wheel-mounted paddles means you can be more selective about which ratio you’re in and for how long.

Standard suspension set-up is strut front, multi-link rear, with many of the components made from aluminium to reduce unsprung weight, and the CLA feels nimble through twisting backroad bends.

Our test car was optioned with the AMG Exclusive Package, which includes adaptive dampers. And no surprise ‘Sport’ mode is severe, and the fillings in your teeth (unless you’re one of those strange people that don’t have any) will be in danger of rattling loose over anything other than a billiard table smooth surface.

By contrast, ‘Comfort’ lives up to its name with a supremely compliant ride without any sacrifice in terms of balance and (taut) body control. The standard 18-inch rims, shod with 225/45 rubber, don’t put a disenable dent in proceedings, either.

The electro-mechanical steering points accurately and delivers a good connection with what’s happening at the front wheels. Assistance is subtle.

Brakes are vented discs up front, with solid rotors at the rear. Purely in the interests of a full and well-rounded review we enthusiastically pushed through some lengthy B-road sections, and the pedal remained firm and consistent.

In short the CLA is a refined city coupe that doubles as a comfortable touring car.

It’s hard to fault Mercedes-Benz when it comes to safety, and the new CLA is loaded with standard active and passive tech.

Active safety tech includes ABS, BA, EBD, stability and traction controls, a reversing camera (with dynamic guidelines), 'Active Brake Assist' (Merc-speak for AEB), 'Adaptive Brake', 'Attention Assist', 'Blind Spot Assist' (with exit warning assistant), 'Cross-wind Assist', 'Lane Keep Assist', a tyre pressure warning system, a reversing camera plus ‘Parking Distance Control’ (front and rear), 'Traffic Sign Assist', a wet weather brake drying function, and ‘Active High Beam Control’.

If all that fails to prevent an impact you'll be protected by the 'Pre-Safe' accident anticipatory system, plus nine airbags (front, pelvis and window for driver and front passenger, side airbags for rear seat occupants and a driver's knee bag), and the 'Active Bonnet' automatically tilts to minimise pedestrian injuries.

There’s also an impact-sensing auto door unlock system, an auto emergency call function and crash responsive emergency lighting, plus a first-aid kit, warning triangle and (five) hi-vis vests in the boot are thoughtful additions.

The A-Class (which encompasses the CLA) was awarded a maximum five ANCAP stars in 2018, and for smaller occupants there are three child restraint/baby capsule top tether points across the back seat, with ISOFIX anchors on the two outer positions.

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.

The Mercedes-Benz range is covered by a three year/unlimited km warranty, which, like Audi and BMW continues to lag 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’ roadside 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.

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