BMW M2 vs Mercedes-Benz C300

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.

Over five decades, the Mercedes-Benz C-Class has pivoted between mastery and mediocrity, and all-too-often relied on that three-pointed star up front to win over buyers.

Thankfully, the W206 is one is one of the better generations. It's easier on the eye, comfier to travel in, more intuitive to use, safer across the board and a huge improvement to drive. On the evidence of the C200 and C300 launch grades, there's newfound depth and consistency to savour.

Sure, prices have gone up, the C200 could use a bit more power, the steering could benefit from a bit more feel, the odd build-quality glitch made itself heard and there's a fair bit of road noise at times, but overall, the C-Class now deserves to be at the top of your luxury medium sedan shopping list.

Particularly if you can afford to stretch to the rorty C300.

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.

If you're checking out the new C-Class for the first time from the front, you'll probably think… hmm, it looks just like the old one, and that's largely true.

But a side view reveals proportions that have changed significantly, thanks to the more raked windscreen, shorter overhangs and cleaner lines, which give it a slightly smaller S-Class look.

Which is more in fitting with where Mercedes wants to place this car against its 3 Series and A4 competitors.

Additionally, the taillights are split for the first time, allowing for a wider boot aperture since the lid now contains some of the lighting elements.

The shrunken limo looks aren't just the whim of some designer or Mercedes-Benz marketing department copywriter, either.

Underneath is an albeit highly modified version of the latest S-Class' MRA2 platform, which results in the longest (at 4755mm) and widest (at 1820mm) C-Class in the series' 40-year existence, as well as the first with this level of electrification capability.

Height and wheelbase dimensions also see a stretch, by 8mm and 25mm to 1450mm and 2865mm over the previous model respectively, and to the benefit of passenger accommodation.

Speaking of which, get used to this new interior aesthetic and general layout – it's a look that's probably going to filter through to most coming non-EQ-branded Mercedes models over the next few years.

From S to C to future E and A classes and beyond. It's a rare instance of trickle-down economics actually working!

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.

One of the best things about the new C-Class is that it's larger and therefore roomier than before. It's also higher quality, easier to use, more comfortable to sit in and - overall - more of a delight to behold.

In contrast, the old C-Class dash looked and felt like it was designed for a much cheaper car, especially compared to Audi's efforts.

Obviously related to the S-Class this time around, it's clear Tesla provided the inspiration for the twin floating screen look and layout, which are just right in their driver orientation and ease of functionality.

There's never really been anything wrong with Mercedes' old front seats, but these AMG Line items are both sumptuous and bracing, keeping their occupants well located ahead of the clever and thoughtfully laid out dashboard.

The brilliantly high-resolution MBUX multimedia and voice-recognition system now works as it should - intuitively and logically, with the screen menus simple to recognise and easy to use, and most without the need to get lost in confusing sub-menus. Just like BMW has managed for years.

If you want to change the instrumentation design, it's now a couple of clearly marked steps, using handily placed switchgear. The same goes for the superb climate control and audio systems. And the wireless Apple CarPlay/Android Auto connected faultlessly and worked a treat. Effortless see-and-push operation all round, backed by concise and classy graphics.

No more degree in Earth-to-Mercedes comm skills required to master this C-Class interior.

Yet there's just enough old-school Benz features to appeal to brand diehards, from the eternal door-card mounted electric seat controls and column-mounted gear shifter, to the deep centre console and turbine face-level air vents. They meld together beautifully with the advanced tech also on offer, like the optional augmented-reality head-up display with 3D-graphics.

Annoyingly, on one of our test cars, that tradition also extended to a couple of squeaks and rattles, proving that maybe Mercedes hasn't quite conquered all its past quality gremlins. And, like most luxury cars nowadays, endless ambient lighting choices are available of dubious taste.

Never mind. This is the finest C-Class front-seat environment since, well, probably the original W210 190E's of the 1980s.

And all those extra dimensions pay dividends in terms of interior space in the back seat.

There's plenty of knee room even with the tester sat behind their 178cm frame; head room is adequate even with the optional sunroof fitted, and there's ample shoulder space. So, it's more comfortable than any C-Class ever has been in terms of sheer dimensions.

Additionally, the rear backrest is well angled, while the cushion is deep enough to provide sufficient thigh support. But the centre perch is a bit of a squeeze for all concerned. Best avoided.

There's also added practicality to be found with the large and deep door pockets, front seat-back map pockets and folding centre armrest, that not only has a tablet holder, but when pressed in twice, also reveals sliding cupholders as well. Clever.

The C-Class rear seat is really lacking for nothing, with face-level air vents, overhead lighting, grab handles and coat hooks all highlighting the level of thought that went into making this a practical compact family sedan.

Plus, the C-Class comes with this folding ski port, which along with the folding rear seats, increases boot volume from 455L to, well, a lot more. While that's not quite as good as others like the BMW 3 Series, it's big enough for this car.

Note that there is no spare wheel, as the tyres are of the limited-distance runflat variety.

Initially, there are two sedan versions of the new W206 series C-Class on offer – the base C200 from $78,900 before on-road costs, and the more-powerful C300 grade from just over $90,400 before ORC.

There's no sugar coating this. These prices represent a shocking $12,000 and $15,100 jump, respectively, over the outgoing W205 equivalents. Which means that, now, even the cheapest C-Class costs significantly more than any of its corresponding direct rivals.

For example, the Audi A4 35TFSI kicks off from $59,900, Volvo S60 B5 Inscription AWD from $62,490, Genesis G70 2.0T from $63,000, Alfa Romeo Giulia Sport from $63,950 and BMW 320i Sport Collection from $69,900 (drive-away). And even the Tesla Model 3 Standard Range (SR) Plus RWD and Polestar 2 SR EVs slip in at under $60K apiece. All before ORCs, BMW-aside.

But the news isn't all bad, because even though prices have jumped, Mercedes reckons it gives you more, as well as the very latest in technology, design and engineering, since the W206 is the newest kid on the block by some margin.

Let's begin with equipment levels.

On top of the front electric seats, satellite navigation, automatic parking, dual-zone climate control, artificial leather Mercedes brands ARTICO, digital radio, remote boot lid closing and 18-inch alloys that the base C200 all came with previously, the new one now adds an AMG Line body kit and interior trim, adaptive cruise control, Lane Keep assist, a 360º camera, auto high-beam headlights and keyless entry/start. These go a long way to offset that $12,000 price hike.

Plus, for the first time, you'll also score a centre airbag between the front seats, fingerprint scanner ID tech for the new 11.9-inch media display and a 48V mild-hybrid system to help cut fuel consumption and emissions. Most of these items are segment-firsts. Note, too, that the engine's been downsized from 2.0 litres to 1.5L. More on that later.

Meanwhile, the C300 gains all of the gear above, as well as a new 2.0L mild-hybrid engine, leather trim, privacy glass and a Driver Assistance Package Plus – a very worthwhile addition since it brings Active Blind Spot Assist, Active Brake Assist with Cross-Traffic Function, Active Emergency Stop Assist and Active Lane Keeping Assist, among heaps more driver-assist safety features.

More details follow in the Safety section below.

Of course, these are just the start of a wave of fresh C-Class models. Soon they'll be joined by the AMG 43 and thunderous AMG 63 sports sedans, as well as plug-in hybrid versions.

So, from a pricing perspective, yes, the new C-Class sedan does come at a premium compared to its direct competitors. But all that kit – including the advanced hybridised and safety technologies that are now either standard or available – presents a compelling value proposition.

Especially as the W206 sedan is measurably larger and thus roomier than before.

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.

Probably the biggest departure compared to any previous C-Class is this generation's switch to direct-injection four-cylinder-only powertrains – including the coming Mercedes-AMG high-performance versions. Now that should be interesting.

As mentioned earlier, the C200's four-cylinder turbo engine is now about 25 per cent smaller in capacity, down from 2.0L to a 1496cc 1.5L twin-cam 16-valve turbo engine. Dubbed the M254, it pumps out 150kW of power at a high 6100rpm and 300Nm of torque between 1800-4000rpm.

That's not to say it's lacking in muscle, though, since it can sprint from zero to 100km/h in 7.3 seconds, on the way to a 245km/h top speed. These outputs are at least a match for the bigger-engined 3 Series and A4 equivalents, by the way.

If it's more you want, then the C300 features a 1999cc 2.0L turbo version of the M254, delivering 190kW at 5800rpm and 400Nm between 2000-3200rpm. This slashes that 0-100km/h time to a speedy six seconds flat. There's also an extra 20kW of overboost available for short periods if you're really in a hurry, while - where legal - it's possible to hit 250km/h.

Both send drive to the rear wheels via a nine-speed torque-converter automatic transmission, while the 48V mild-hybrid system, dubbed EQ Boost, employs an integrated starter-generator and lithium-ion battery that provides an additional 15kW and 200Nm of electric boost at low engine speeds.

So, while it doesn't ever run purely on electricity, the electrification tech certainly either brings more punch or takes the load off the petrol engine, depending on how you're driving it.

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.

Remember when I said that the C-Class moved to an all-four-cylinder engine range? Well, that's primarily to help it better meet fuel consumption, efficiency and lower emission targets.

On the Australian combined fuel consumption cycle, the C200 manages 6.9 litres per 100km – and that's extremely impressive for a medium-sized sedan weighing almost 1.8 tonnes. So is the fact that the larger-engined C300 returns only 0.4L/100km more at 7.3L/100km. Fitted with a 66-litre tank, these numbers suggest that the former can average nearly 960km between refills while the latter can manage just over 900km.

These figures translate to averages of 157 and 164 grams per kilometre of carbon dioxide emissions respectively. On the flipside, both these Euro-6 emissions rated engines require 98 RON premium unleaded petrol to deliver their best.

So much for lab tests. Out in the real world, we drove both cars for several hundred kilometres on a hot summer's day, from inner Melbourne during peak-hour traffic, to some great curvy rounds out in central Victoria, featuring some tight corners and ample opportunity to really stretch both cars' legs.

Over these routes, we averaged an indicated 8.4L/100km in the C200 and – astonishingly – 7.4L/100km in the C300. Yes, the larger and more powerful engine proved more economical.

Clearly, along with the advanced aerodynamics, engine stop/start system and 48V mild-hybrid tech, all that downsizing works. No wonder Mercedes deemed it unnecessary to bother with diesel engines for this generation C-Class.

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.

There has been a philosophical shift in how the C-Class is presented.

Even with their standard-in-Australia AMG Line package, the regular grades like the C200 and C300 are now leaning into the brand's luxury heritage, while the BMW-baiting sports sedan versions will be left to the coming AMG versions.

And this in turn profoundly informs how the W206 drives.

Even with the optional Sports Pack on 19-inch wheels, the C200 as tested finally feels like a premium midsized sedan experience. Muted at start up, the 150kW/300Nm 1.5L turbo steps off the line smartly and smoothly, its nine-speed auto shifting effortlessly through the gears to keep the engine feeling lively and lusty.

Around town it's easy to mistake the engine as a larger-capacity unit, since throttle response is instantaneous, with little to no lag detectable. It's a strong start for a base powertrain, especially as the C200 settles into a relaxed cruise at freeway speeds. Cycling through the driving settings also reveals how feisty the 'Sport' mode is.

But the 1.5L's lack of size becomes obvious the moment you need to overtake quickly, or when a quick squirt of acceleration up a hill is required, because the engine needs plenty of revs to approach that 6100rpm power peak. While still pretty brisk in these situations, it's also fairly vocal too, with a sense of having to work hard to maintain momentum.

Switching to the C300 highlights how much better suited the 190kW/400Nm 2.0L turbo is to highway driving, leaping forward with much more force and conviction, across the entire performance spectrum. In every metric, this is a better choice – throttle response, mechanical refinement, cruising ease. And the fact that the onboard computer showed less fuel consumption cements our preference for the larger-hearted C-Class.

In fact, both models possess a chassis that feels like it could do with a whole lot more power. Light and tight around town, the steering weighs up nicely at higher speeds, with a linear and reassuringly planted feel. The same also applies to how confident and controlled the Mercedes feels through fast, tight turns, yet settles into a relaxed and comfortable tourer along long, straight stretches of road.

It's a pity, then, that such dynamic agility and prowess doesn't really involve the driver, since the steering feels quite isolated from what's going on underneath; for the vast majority of C-Class buyers, that's fine. But, as a quick spin in any latest BMW 3 Series or Jaguar XE will reveal, there isn't an intimate, two-way connection going on here. That's probably going to be reserved for the AMG models.

Our C200 rode on bigger wheels and steel springs, while the C300 was fitted with optional adaptive dampers. In the previous-generation C-Class, the differences would be stark: a busy and jittery ride in the former, compared to soft yet still unsettled suspension in the latter.

That's all ancient history now, as even the 'passively' suspended C200 now isolates its occupants from the rough and tumble of our inconsistent roads. Still firmish, but no longer harsh.

And the C300 with adaptive dampers seems downright plush by comparison, while offering the driver personalisation options within the aforementioned driving models to tailor the steering, performance and engine sound settings that best suit the prevailing mood.

Too bad there's some road and tyre noise intrusion heard inside when driving over coarse bitumen roads. This is a common pitfall amongst German vehicles in Australia.

Still, it doesn't detract from the fact that the whole chassis set-up can at-last cushion and cosset occupants like, well, a mini S-Class.

Which is the whole point of the W206 C-Class. It now majors on comfort and reassurance like the better Mercedes-Benz models used to, while still being suave and sprightly enough to be a memorable – if not over-exciting – drive.

As a result, the C300 especially is a much-more likeable car than past iterations. Just remember to tick the adaptive damper option for the most optimal experience. Job well done, Mercedes.

The W206 C-Class has not been crash-tested yet by ANCAP or European affiliate EuroNCAP, so does not have a star rating. However, Mercedes-Benz claims it has striven to create one of the safety vehicles on the planet.

To that end, there are now 10 airbags fitted, including dual-front combined pelvic/thorax airbags, front centre airbag, rear side airbags, window airbags and driver's knee airbag.

Plus, you'll find Autonomous Emergency Braking front and rear (including for cyclists and pedestrians, at speeds from 7km/h to over 200km/h), adaptive cruise control with active stop/go, a 360 degree camera, Active Parking Assist, drowsy driver monitor, Active Lane Keeping Assist, Blind Spot Assist, ABS anti-lock brakes with Brake Assist, Adaptive Brakes with Hold function, brake drying and Hill Start Assist, electronic stability control, traction control, dusk-sensing LED lights, rain-sensing wipers and runflat tyres with tyre pressure warning.

The C300, meanwhile, adds Driving Assistance Package Plus, with features such as 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… basically, this is where the car actually intervenes to help avoid accidents and impacts. There's also the PRE-SAFE side accident anticipation and protection system.

Both models also feature two ISOFIX child seat restraints as well as three top tethers for straps.

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.

Kudos to Mercedes-Benz for being the first luxury manufacturer in Australia to offer a five-year/unlimited kilometre warranty – matching most other mainstream makers. Lexus and Audi have only recently followed suit.

A five-year roadside assistance subscription is also included. Service intervals are 12-monthly or at every 25,000km, whichever occur first.

Additionally, a four-year capped price service plan is available, at $550 for the first year, $900 for the second, $1000 for the third and $2450 for the fourth, totalling $4900.

Alternatively, buyers can also choose three pre-purchase service plans to save a bit of money, but these must be bought prior to the first service.
