Mercedes-Benz CLA-Class vs BMW 2 Series

What's the difference?

The new AMG C 43 may lack the drama and excitement we’ve come to expect from the German performance brand, but that doesn’t mean it’s a bad car. Yes, it could be more extroverted and the ride could be improved, but this is still a sharp-looking sports sedan with loads of punch.

This is a car that speaks to its times, with ever-stricter emissions regulations making it harder and harder for car companies to produce loud, wild and charismatic cars. So Mercedes-AMG has worked within those boundaries and come up with a car that retains at least some of those core elements that has made the brand so desirable over the years.

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

It may be expensive for a small coupe. And EVs have reframed performance standards to the detriment of most internal combustion engine sports cars like this – at least for acceleration times. But the M240i xDrive Coupe is far more than just about numbers, imbuing the soul and spirit of what makes this brand’s vehicles so enjoyable and memorable to drive.

A unique and most-welcome survivor today, the MY25 makeover takes all that, and improves the interior, to be at the heart of what BMW has traditionally done best (styling aside). We found parting with it at the end of our term very difficult.

Mercedes has created something of a problem for itself with its decision to introduce AMG styling packages for the majority of its range, including the C-Class.

It means the C 43 has to walk a fine line between looking like a unique AMG model, rather than just a C300 with a bodykit and not out-doing the C63.

To that end it has AMG’s now familiar grille with vertical bars, the unique and complex-looking 20-inch alloy rims and a small lip spoiler on the boot. But otherwise it is surprisingly understated for an AMG, lacking the more obvious and muscular stance of previous AMG offerings.

Inside, there’s a similar theme, with the typical Mercedes-Benz luxury appointments but with a sportier, AMG twist. The steering wheel is chunky and comes with AMG branding, metallic shift paddles and a pair of rotary dials/buttons that allow you to alter the various drive modes and settings.

The one on the right allows you to switch between the pre-set Comfort, Sport, Sport+ and Individual modes, while the one on the left can scroll between the various individual aspects to tailor the settings to the conditions.

In typical modern fashion the design is tech-laden, with a digital display for the instrument panel (that can be switched between various graphics) and a large, tablet-style central multimedia touchscreen that controls the majority of the car’s non-driving functions.

BMW has iconic form when it comes to coupe, err, form.

Consider the timeless E9 Coupe of 1968, its elegant E24 6 Series successor of 1976 and the chiselled E31 8 Series of 1990.

Even the sinewy E82 1 Series Coupe of 2007 still resonates.

But, despite boasting long-nose/short-tail proportions, today’s G42 looks awkward from some angles, like a Lego version of the preceding F22 of 2014, complete with cartoonishly aggressive detailing that don’t sit happily on the car.

Not Munich’s finest moment. Still, as one of the last surviving small coupes, we’re still very glad it exists. And, in a rare case of more being more, this M240i’s body kit disguises some of the heavy-handedness.

So, what’s new here? Barely earning the facelift tag outside, the MY25 2 Series Coupe gains extra colours, restyled alloys and revised exterior trim, with more body paint in the lower parts and rear apron, as well as high-gloss black for the M240i’s mirror caps.

Inside, the modifications are more profound, updating to BMW’s 'Operating System 8.5', offering improved functionality and all housed within a fetching, single-piece rectangular display screen that also takes in the instrumentation.

Along with a flat-bottomed steering wheel, redesigned air vent knobs, fewer buttons, revised trim and different ambient lighting, they refresh what was a dated-looking cabin.

The new C-Class has grown slightly in size compared to the model it replaces, most notably with a 26mm increase in the wheelbase which you can feel in the cabin.

The front seat space is good, with excellent adjustability for the power-adjustable seats and steering column. I had no trouble finding my ideal seating position which makes for a more enjoyable and uncompromised driving experience.

Rear space is a bit tighter (which is typical for this segment/size of vehicle), but thankfully the standard seats do have very deep sculpting in the backs which allow for more knee space and foot room.

However, at approximately 180cm (six-foot), I wouldn’t like to sit behind my seating position for long periods as my knees were touching the seat back, and headroom is compromised with the panoramic glass roof.

In terms of small item storage there’s a lidded console box in between the front seats as well as a pair of cupholders and a small tray where you can place your mobile phone.

It’s worth noting, though, that early examples of the C 43 in Australia do not have a wireless smartphone charging pad, with that reportedly being introduced from February production.

While that’s good news, it’s not really competitive in this day and age to offer a car costing six-figures without such technology.

There’s also only a single USB-C power outlet in the front, which is another disappointment, but there is a pair in the back.

Mercedes does win some points back for a respectable 455-litre boot, which has a nice wide load opening that will make packing luggage easier.

You could be forgiven for thinking you’ve stepped into a mid-sized rather than small coupe, with today’s G42 being larger in every area except wheelbase than an E46 3 Series Coupe of about 25 years ago.

Length, width, height and wheelbase dimensions are 4548mm, 1838mm, 1404mm and 2741mm, respectively, which make for a surprisingly easy-to-access and spacious cabin – at least for adults up front.

In fact, if nobody is sat behind, even a 200cm-plus individual can stretch out. German cars are great at accommodating the 99-percentile people. And head room’s not bad either, even with the standard sunroof.

BMW’s are about driving, so no shocks to learn that the M240i’s driving position is first class. Sat low and snug, this is a suitably sporty yet incredibly comfortable and high-quality environment, aided by nicely bolstered M Sport seats, a lovely steering wheel and a beautifully presented dashboard. Everything fits like a glove.

If the notion of reducing the number of buttons in the newly-extended electronic interface raises red flags (how many times have we moaned about this in most software-based Chinese vehicles?), rest assured: the M240i’s ergonomics are spot-on.

There are still plenty of switches alongside the iDrive controller and gearshifter for all major vehicle functions, Porsche-style, as well as big old physical buttons for the (soaring) audio, to back up the screen shortcuts for more-detailed functions. It only takes a few moments to learn how easy and intuitive the whole set-up is. BMW leads the way here.

Crisp, clear and colourful digital graphics almost make up for the fact that the gorgeous old analogue dials of old are extinct. Instead, the company serves up unremarkable angular instrument displays and electronic readouts. Very comprehensive and informative, they do the job, but are utterly bereft of character or style. It’s as if Munich’s designers have forgotten how to make things look pretty nowadays. Hang on, do we see a pattern emerging here?

More solid Teutonic sensibility – this time far-more artfully served up – can be found in the excellent ventilation system, ample console-sited storage and pleasingly deep door pockets, highlighting how easy the M240i is to live with.

Crash regulations demand central posts, so no pillarless sides unfortunately in this modern coupe, but frameless door glass is nice (and assists in entry/egress when retracted), enhancing that sporty sensation.

The flipside is poor side and rear vision for the driver, but – frankly – it is otherwise difficult to fault the M240i’s interior layout and presentation.

Even the back-seat area tries hard.

The seats whirr forward and back (slowly) to increase/decrease the narrow aperture as required (using a shoulder-height lever within easy reach), though you’ll need to be pretty flexible accessing the two-person buckets that await. Once ensconced there, there’s sufficient space, padding and support for most folk of up to about 180cm to travel in reasonable comfort, as long as the front-seat occupants aren’t in maximum chaise longue mode and journeys aren’t too long. The quite-upright backrest angle can’t be adjusted.

Just ensure the climate control is on. Things can become pretty stuffy, quickly. And be thankful for the air vents, extended glass area, middle armrest with cupholders and reading lights.

Further back, there is a large-ish, 390-litre boot with a low, wide and flat floor, that can be extended by tugging on a handle to drop the 40/20/40 split/fold backrests as required.

The usual tie-down hooks, lighting and power outlets are present, but you’ll search in vain for a space-saver wheel. Just the dreaded 'tyre mobility kit' that – once deployed – will likely ruin your tyre and cost hundreds to replace. No thanks.

A gashed tyre. No phone coverage. What a way to ruin a great drive day out on your favourite rural roads and in such an immensely enjoyable car. Australia demands a spare tyre.

The good news is, the G42 in 230i and flagship M2 retain the traditional longitudinal-engined/rear-wheel drive set-up, though the M240i has all-wheel drive (xDrive in BMW-speak) to help keep things under control.

All the other existing 2 Series models (basically, those with more than two doors) are transverse/FWD-derived.

Now, the bad news is that, from $102,100 (all prices are before on-road costs), the M240i is considerably more expensive than before. You can no-longer buy a traditional six-cylinder BMW coupe for under six figures. The continuing 230i Coupe, from just under $80K, uses a (albeit lovely) four-pot turbo.

At least the Mexican-made M240i isn’t short of equipment.

You’ll find an 'M Aerodynamics' package, 'M Sport' package that includes drive modes, M suspension with adaptive dampers, M brakes, M differential, M variable steering and M… more.

Additional items include adaptive LED headlights, leather upholstery, electric and heated sports front seats with driver’s side memory, climate control, sunroof, adaptive cruise control, paddle shifters, a 12.3-inch instrument cluster, a 14.9-inch multimedia display, 'Hey, BMW' voice control, a heated steering wheel, a head-up display, auto parking, a surround-view camera, 14-speaker Harman Kardon audio, digital radio, wireless charging, Apple CarPlay/Android Auto, emergency services access as part of a three-year subscription, electric heated/folding M exterior mirrors, ambient lighting, 19-inch alloy wheels and a tyre-repair kit ­– in lieu of a spare wheel.

Our car as-tested also included 'Brooklyn Grey' metallic paint ($1700), 19-inch M light alloy wheels with performance tyres ($2800) and the M Sport Package Pro material/trim package ($1900), helping to bump up the price to $108,500. No reversing nearside mirror-dip is a bit stingy, though.

Still, there’s also a decent wad of advanced driver-assist systems, including AEB front and rear, lane-support tech and various monitors. Read more about that and more in the safety section below.

The near-$20K price jump since 2022 also means the M240i is now more expensive than the Z Nismo and Mustang Dark Horse and is now rubbing shoulders with the (BMW-based and built) Toyota Supra Track Edition and even the MG Cyberster Dual Motor.

And, speaking of electric vehicles, as before, the now-$81K Tesla Model 3 Performance’s astounding 3.1-second acceleration is in another league.

No, the M240i is about traditional BMW values harking back to 'The Ultimate Driving Machine' era. Premium, driver-focused German grand touring sports luxury coupe, cabriolet or convertible.

From that perspective, the two-door 2 Series is the cheapest by a fair margin and in a league of its own.

The biggest talking point about this new car is the engine, with AMG downsizing from the old C 43’s six-cylinder to a 2.0-litre four-cylinder turbocharged petrol engine.

But it’s not just any turbocharged four-pot, because it is fitted with technology that Mercedes claims has been inspired directly from its Formula One team.

While the F1 team engine facility is based in England, this engine was designed and developed by the Mercedes-AMG team at its Affalterbach headquarters, but the concept of the electric turbocharger reportedly comes from the engine that powered Lewis Hamilton to multiple world championships.

The electric exhaust gas turbocharger - to give it its official name - uses a small electric motor on the turbocharger shaft to spin up the blades without having to wait for any exhaust gases to pass through it first.

To power the electric turbo the C 43 is equipped with a mild-hybrid 48-volt electrical system.

Mercedes claims this means reduced lag and improved throttle response for a sportier driving experience. 

It also helps make this small engine produce big amounts of performance, with AMG extracting 300kW of power and 500Nm of torque from this 2.0-litre, which is more power than the previous six-cylinder C 43 managed.

The engine is paired to a nine-speed multi-clutch transmission, which isn’t a dual-clutch with a pair of clutches operating on every second gear ratio, but instead uses a “wet start-off clutch” for better take-offs and smoother shifting on the move (at least in theory).

Power is sent to the road via all four wheels thanks to Mercedes’ 4Matic all-wheel drive system.

As before, the M240i employs a 3.0-litre direct-injection turbo-charged in-line six-cylinder petrol engine, making a heady 285kW of power at 6500rpm and 500Nm of torque between 1900rpm and 5000rpm.

A ZF-supplied eight-speed torque-converter automatic transmission is fitted (and, sadly, no manual is available), driving all four wheels via an AWD system with an M Sport-tuned differential.

Despite the smaller engine you can hardly call the C 43 miserly, with a claimed combined urban/highway cycle rating of 9.1-litres per 100km. That’s only a 0.2L/100km improvement over the old six-cylinder.

On test, which included a return trip from Sydney to Bathurst via motorways and some dynamic back road driving, we saw a return of 11.8L/100km on the car's onboard computer.

While hardly hybrid-worrying, it’s impressive to think that driven modestly, such a potent engine can return a single-digit fuel figure.

Rated as a Euro 6d-compliant vehicle, the M240i’s average combined fuel consumption figure is 8.0 litres per 100km, for a carbon dioxide emissions average of 185 grams/km.

With a 52-litre tank brimmed with premium unleaded petrol (98 RON minimum is recommended), that should result in about 650km between refills on average.

Over a mix of urban and highway driving, we managed 8.9L/100km, which is better than the pre-facelift version’s 9.6L/100km. That’s impressive stuff for a performance-orientated sports coupe.

Let’s start with the good news. The new Mercedes-AMG C 43 is a quick car. The engine may be small in size but the electric turbocharger does its thing and provides plenty of punch.

You can get a performance boost, too, thanks to the belt-driven starter generator, which acts as a mild hybrid and gives you a surge of 10kW for a brief period if you need a sudden burst of extra speed.

The chassis is well-sorted, too, at least from a dynamic point-of-view. The rear-wheel steering can provide up to 2.5 degrees of turning, which improves handling at speed and manoeuvrability when parking.

However, there are some less-impressive elements to the C 43, too. The obvious one is the drama, or rather the lack thereof.

As I said at the beginning, the C 43 has never been as wild or raucous as the V8-powered C 63, but when you buy an AMG there’s a rightful expectation that it will provide some thrills.

The C 43 simply doesn’t have that character about it. Yes, it’s fast, but it produces that speed with efficiency rather than excitement.

And it’s not an engine size problem, because even the 2.0-litre four-cylinder A 35 and CLA 35 offer more ‘wow factor’ than the C 43.

Yes, the engine makes noise under acceleration (and it can be altered between discreet and sporty) but even at its best it sounds muted and lacks the evocative tone of a V8 or six-cylinder engine. 

Another disappointment is the transmission calibration, with the gearbox awkwardly shifting out of first gear on multiple occasions during our test drive.

In the taller gears it felt smooth enough cruising along, but given its low speed shifts we’d like to spend more time in the urban environment before passing final judgement. 

The other notable element of the driving experience we struggled with was the ride quality. While fine on the smoother motorways, our test drive included time on some patchy country back roads and the C 43, even in the ‘Comfort’ suspension setting, was simply too firm.

Riding on low profile tyres, the adaptive dampers struggled to isolate the cabin from the imperfections in the road, leading to a fussy ride at times.

Overall the C 43 is a good car, but it feels like there are still some areas where Mercedes could improve it to make it really live up to the AMG badge.

The M240i xDrive’s specification reads like it’s straight out of BMW fan fiction.

Nestled within a shrunken 3 Series-derived 'CLAR' platform brandishing near-50:50 weight distribution, stuffed between beefed-up struts up front, is a strident in-line six, driving the rear or all four wheels via an M Sport differential and held up by a multi-link rear axle.

The promise here is an athletic driving machine on one hand and a cosseting grand tourer on the other, but whether the M240i can walk that fickle red line as effortlessly four years on… well, that’s what we’re here to find out. As we said earlier, sub-3.5s Teslas and the like have really messed with the bang-for-your-buck playbook since 2021.

Luckily, the reality only reiterates the 2 Series Coupe’s place in the sun. Rather than the anodyne (or artificial) whine of an electric motor, here instead is one of the greatest modern engines in the world, mated to arguably the best auto transmission ever in existence.

That’s a terrific start. And, once the button is pressed, the M240i’s performance bandwidth is deeply moving and immensely satisfying.

With a kerb weight of 1690kg, the M240i’s power to weight ratio is an impressive 168.6kW/tonne, helping it to scoot from standstill to 100km/h in 4.3 seconds, on the way to an electronically-limited top speed of 250km/h. Note that the M2 flagship is just 0.3s quicker to 100.

Pottering about town in its most benign ('Eco Pro') setting, the B58-hearted Bimmer slinks about gingerly, purring like a content tabby while skimming along over all sorts of urban roads like a luxury car costing a lot more should, taking everything in its stride. Given this is what driving is like for most people most of the time, the BMW nails it.

More throttle unleashes a surging snarl as the BMW’s speed steps up, with varying degrees of urgency according to the driver’s will and desire. Racing up through the gears, the German straight six feels like it has barely stirred; like things are just warming up.

In conjunction with Sport mode, here is where the M240i really starts to take off, leaping into action, engine roaring as speeds soar as if every road is a stretch of derestricted autobahn. The pace of this coupe is quite remarkable. Planted yet precise, the steering firms up as the chassis hunkers down, and you’re left in awe of how calm and composed the car constantly feels. Even in pouring rain.

As the roads start to snake and twist, the BMW glides through the chosen line with startling grip and confidence, without ever feeling nervous or twitchy in standard traction settings, regardless of surface or weather conditions. That’s the AWD doing its thing.

The M240i is all about nuance and control, whether you’re talking steering, handling, roadholding, braking or electronic intervention. It is refreshing to feel so connected to the driving experience so intimately.

As we said back in 2022, plonking for Sport Plus mode, with the stability and traction nannies neutered, is an easy street to big old oversteer spills and thrills, if so desired.

And then, you’re back in Eco Pro, crawling along in cocooned comfort and relying on the ADAS tech to waft you along, before being back in 'Individual' mode as the road ahead clears, with powertrain in 'Sport' but the suspension in 'Comfort'; just right for times when you just want to streak ahead of slower traffic without pummelling your spine. It’s all there for you. The M240i can do it all.

Inevitably, in Sport mode the ride’s firmness can be fatiguing on bad urban roads. Likewise, the tyre noise over coarse bitumen is tiring over longer drives. And it is all too easy to exceed the speed limit.

Earlier, we said we prefer this over the extroverted, track-focused M2, despite the latter’s astounding speed, thunderous soundtrack and tremendous dynamic capabilities, and that’s because of the M240i’s ability to deliver pleasure with everyday user-friendliness. Plus, the performance flagship is only 0.3s quicker to 100.

Maybe the latest base manual M2 might change our minds.

As it stands, on the move, the M240i is BMW in full flight, staying true to brand values but without frying your nerves or depleting your bank account too much. We love it and you should too.

No ANCAP rating exists for the G42 M240i Coupe in Australia.

However, a 220d diesel coupe (not available here) tested by Euro NCAP back in 2022 managed a four- out of five star result, with pedestrians/vulnerable road user protection and emergency lane keeping recommended for improvement.

The MY25 M240i comes with a raft of advanced driver-assist systems, including AEB (operational from 5.0km/h to at least 210km/h and with cyclist and night-time operation), forward collision warning, front-cross and rear-cross traffic alert, 'Rear Collision Prevention', 'Speed Limit Information', lane departure warning with passive steer assist (operational from 70km/h), lane keep with active assist, blind spot monitor and driver attention monitor.

It also comes fitted with 360-degree view cameras, parking sensors, anti-lock brakes with electronic brake-force distribution and brake assist, stability control, traction control, corner braking and six airbags, made up of dual frontal, side chest and head-protecting airbags for the first row and side chest protecting airbags for the second row.

Speaking of the back seat, a pair of ISOFIX points as well as two top tethers for securing child seats are present.

The C 43 is covered by Mercedes’ five-year, unlimited kilometre warranty, which has become the new standard for the luxury car market.

Service intervals for the car are at 12 months/25,000km, which is on par with industry standard.

Mercedes-Benz Australia will offer a service plan for the C 43, prices were yet to be confirmed at the time of publication but the company has indicated it will be similar to the C300. 

That means $550 for year one, $900 for year two, the third service costs $1000 and the fourth year service costs $2450 - for a total of $4900 for the first four years of ownership.

BMW offers a five-year/unlimited kilometre warranty, matching all of its German rivals, as well as three years of roadside assistance.

As always, servicing frequency is condition-based, depending on how they’re driven, amongst other factors, with an indicator on the instrument panel to alert the driver/owner. That said, our advice is to always visit your BMW dealer annually or at every 10,000km, just to be certain.

Capped-price servicing is not offered.

However, the ‘BMW Service Inclusive Basic package’ is available at extra cost, covering scheduled servicing for five years/80,000km, as long as the scheme is subscribed to before the end of the first 12 months of first registration. A 2 Series should cost from $2380.
