BMW M2 vs Mercedes-Benz CLA-Class

What's the difference?

As the ultimate form of the current M2, the CS distils the best aspects of what everyone loves about BMW into one tidy little package.

The driving experience is nothing short of divine, even if the manual gearbox shifts could be better, while the firecracker engine kicks things up to a whole new level.

If only BMW offered more equipment and safety to round out the $140,000 pricetag, or maybe they should have leaned harder into the lightweight aspect and ditched the rear seats to make the M2 CS even more special.

At the end of the day though, the M2 CS is still an unbelievably appealing driver’s car, and I can’t wait to see what BMW has in store for the next one.

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.

We’re already big fans of the way the M2 looks, it’s just the right size and has the perfect proportions for a sporty coupe, and the CS just takes things to another level.

From the outside, the M2 CS scores a noticeably bigger bonnet bulge, as well as a vented hood to improve airflow.

The front splitter, side mirrors, skirts, bootlid spoiler and rear diffuser are also finished in carbon, and add to the car’s aggressive demeanour.

Filling the wheelarches are 19-inch wheels finished in black, but tucked behind those are massive drilled brake rotors and large calipers painted in red.

To call the M2 CS exterior design sporty would be an understatement, but we do have to point out that the Alpine White of our test car did look a little boring, despite the extra bling.

If we were buying one? We’d option the stunning Misano Blue hero colour with gold-coloured wheels to really turn heads around town and at the racetrack, although they will add another $1700 and $1000 respectively to the already dizzying price.

Inside, the M2 CS is let down a little by a spartan interior, which looks like it’s been lifted from the cheapest 2 Series coupe, due to the lack of climate-control screen.

However, BMW does try its best to spice things up with very tight-fitting bucket seats, an Alcantara steering wheel, CS-branded dashboard and that carbon-fibre transmission tunnel.

It’s definitely a case of function over form , but the lack of interior flare means you focus more on the road ahead than anything else, which is no bad thing when you have 331kW and 550Nm being sent to the rear wheels.

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.

Measuring 4461mm long, 1871mm wide, 1414mm tall and with a 2698mm wheelbase, and just two doors, the M2 CS isn’t exactly the last word in practicality.

Of course, front passengers are afforded plenty of space, and the electronically adjustable bucket seats allow you to get into the right position to row through the gears and eat up the road.

Storage is limited, however, with average-sized door bins, two cupholders, a small wallet/phone tray, and that’s it.

BMW is generous enough to include a single USB port to charge your device, but its location, where the armrest should be, means you’ll have to get creative with cable management to make it really work if you want to keep your phone in the tray under the climate controls.

Predictably, the two rear seats are less than ideal for anyone tall, but there is plenty of leg and shoulder-room.

A small centre-storage tray is fitted back there, as well as Isofix points for the seats, but there isn’t a whole lot to keep rear occupants entertained. They'll probably be too frightened to care.

Opening the boot reveals a small aperture that will swallow 390 litres, and is shaped in such a way that a set of golf clubs or some overnight bags will fit in nicely.

There are some luggage tie-down points and netting to keep your belongings from rolling around, and the rear seats fold down to accommodate longer items.

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.

We’ll get to the major change under the bonnet shortly, but another significant alteration for this latest C 43 is the price.

It now starts at $134,900 (plus on-road costs), which pushes it well above its market rivals, the BMW M340i xDrive and Audi S4, which start at $104,900 and $106,200, respectively.

However, Mercedes has added more technology under the bonnet and loaded the C 43 up with standard equipment, including its '4Matic' all-wheel drive system, adaptive damping, rear-wheel steering and 20-inch alloy wheels.

In terms of creature comforts, the C 43 is well-appointed, with leather upholstery, a head-up display, augmented reality navigation, a panoramic sliding sunroof, and a Burmester 3D surround sound system.

There are two option packages for the C 43. The 'Digital Light Package' costs $2400 and adds Multibeam LED headlights with 'Ultra Range' highbeam, 'Adaptive Highbeam Assist Plus' as well as active light function and cornering light function.

The 'Performance Ergonomics Package' includes AMG Performance front seats, an AMG Performance steering wheel in Nappa leather and microfibre and the 'AMG Track Pace' system for an additional $5200.

Powering the BMW M2 CS is a 3.0-litre twin-turbo ‘S55’ six-cylinder engine, developing 331kW/550Nm.

With drive sent to the rear wheels via a six-speed manual or seven-speed dual-clutch automatic transmission, the M2 CS can accelerate from zero to 100km/h in 4.2 or 4.0 seconds respectively.

Peak power is available at a heady 6250rpm, while maximum torque comes on stream from 2350-5500rpm.

The M2 CS actually put out as much grunt as the outgoing M3/M4 Competition, because it uses the same engine, and to say the amount of performance on tap is explosive would be to talk up explosions. This is a serious amount of bang for your buck.

The M2 CS easily outclasses the likes of the 280kW/460Nm Jaguar F-Type V6, 306kW/410Nm Lotus Evora GT410 and 294kW/420Nm Porsche Cayman GTS 4.0.

I do have to draw attention to the manual gearbox of our test car, though, which was great, but not excellent.

With such engaging shifters fitted to the Honda Civic Type R, Toyota 86 and Mazda MX-5, I expected rowing through the gears would be nirvana, but it was merely OK.

The throws are a little too long for my liking, and it takes just a bit too much effort to slot it into the right ratio. Still, we should all be glad to see a manual offered here, and I'm betting it is still a better option for purists than the auto.

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.

Official fuel-consumption figures for the M2 CS are pegged at 10.3 litres per 100km, while our week with the car yielded a more realistic figure of 11.8L/100km.

Engine start/stop technology is included to keep fuel consumption down, but our week with the car was spent mainly in Melbourne’s inner-city streets, with three trips out of town looking for some winding country roads.

No doubt if we were more restrained with our throttle application, we could have kept that fuel consumption figure down, but a sub-12L/100km result is still great for a performance car.

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.

Let me be clear; driving the M2 CS is a simply sublime experience.

The M2 was always close to the top of the best modern M cars, and the CS simply cements its position as the king.

Step inside and the bucket seats and Alcantara steering wheel make sure you know you are in something special.

Push the red starter button and the engine comes to life, with a racy growl from the new exhaust system that immediately brings a smile to your face.

Out on the open road, the adaptive dampers fitted to the M2 CS do a good job at soaking up bumps and road imperfections, but don’t expect it to suddenly become a comfortable and cosseting cruiser.

The ride is firm in all settings, but dial it up to ‘Sport Plus’ and comfort really takes a hit, especially on the uneven inner-city roads of Melbourne, with its criss-crossing tram tracks.

Escape the unkempt roads of the city for the smooth blacktop of the country, though, and the M2 CS really flexes its handling prowess.

The Michelin Pilot Sport Cup 2 tyres fitted as standard also help in this regard, and while the rear end will step out with 331kW pushed through them, if you want to stick to the racing line and clip that apex, the M2 CS is a more than willing participant.

The suspension isn’t the only thing that can be changed, however, with steering and engine adjustments also available.

We found the best setting to be maximum-attack mode for the engine and suspension, while keeping the steering in its lightest setting, and even with the steering weight turned way down, the feedback and feel from the road is enough to communicate exactly what the M2 CS wants to do.

BMW has definitely nailed the feel of the M2 CS, which almost eggs you on to go faster and faster.

When things get a bit too furious, it is also comforting to know that the massive 400mm front discs and 380mm rear discs with six- and four-piston callipers respectively are more than up to the task of scrubbing speed.

I only wish I could have explored the capabilities of the M2 CS in the more controlled environment of a racetrack, because out on the open road, the M2 CS definitely still feels like it has so much more to give. And everything about this car just screams Race Track Time. Loudly.

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 C43 gets a comprehensive list of safety equipment that leaves little out. Obviously there are the usual passive safety items, like 10 airbags, including dual-front combined pelvic/thorax airbags and a front centre bag that drops between the front seat passengers to minimise the chances of a head clash.

Also included as standard is autonomous emergency braking front and rear (covering speeds between 7.0-200km/h), adaptive cruise control with active stop/go, a 360-degree parking camera, 'Active Parking Assist', 'Active Lane Keeping Assist', 'Blind Spot Assist' and, of course, anti-lock brakes with 'Brake Assist' and 'Adaptive Brakes' with Hold function and electronic stability control.

Also included are dusk-sensing LED lights, rain-sensing wipers and run-flat tyres with tyre pressure warning.

The C43 also comes equipped with Mercedes’ 'Driving Assistance Package Plus', which adds even more safety gear. This includes 'Active Blind Spot Assist', 'Active Brake Assist with Cross-Traffic Function', 'Active Emergency Stop Assist', 'Active Lane Change Assist', 'Active Lane Keeping Assist', 'Active Steering Assist', and 'Active Stop-and-Go Assist'.

While the C43 hasn’t been specifically crash-tested, the latest C-Class was rated by ANCAP with a five-star score for all models except the upcoming C 63 S E Performance.

Like all new BMWs, the M2 CS comes with a three-year/unlimited-kilometre warranty, which falls short of Mercedes’ benchmark five-year/unlimited-kilometre offering.

Scheduled service intervals are every 12 months or 16,000 kilometres, whichever comes first.

Buyers can opt for a ‘Basic’ or ‘Plus’ service plan that covers the car’s first five years, priced at $2995 and $8805 respectively.

The ‘Basic’ plan covers oil changes, air filters, brake fluids and spark plugs, while the ‘Plus’ service adds replacement brake pads and discs, wiper blades and clutch.

With an annual cost of $599 or $1761 for maintenance, the M2 CS is actually pretty affordable to service.

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.
