Mercedes-Benz C300 vs Subaru Crosstrek

What's the difference?

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.

It’s not perfect, in fact, the Crosstrek has a few factors that would probably turn off groups of buyers at a time, but Subaru knows its audience isn’t ‘everyone’.

Subaru customers aren’t trying to get their fuel efficiency below 4.5L/100km, nor find the car with the most luxurious interior. They’re looking for a practical Jack or Jill of all trades, which the Crosstrek does rather well for its segment.

Few small SUVs are as agreeable on rough and unsealed roads without sacrificing suburban comfort, while its features list is practical and provides plenty for the money.

Unfortunately, the hybrid system is a little underwhelming, and if it’s the main draw of the Crosstrek for you, it could be worth considering the less expensive ($38,590) Hybrid L or even a hybrid rival like the Toyota Corolla Cross or Mitsubishi Eclipse Cross.

If the all-round ability of the Crosstrek is the draw, however, the non-hybrid L is still an excellent offering and doesn’t use a lot more fuel than the Hybrid - plus it’s several grand cheaper at $41,490.

The Crosstrek is great for active people who need a bit of flexibility in one car but for the vast majority, the hybrid probably isn’t the sweet spot in the range. However, that won’t hinder the Crosstrek as an overall model, its popularity is already proven, and the option of a Hybrid puts Subaru a little closer to the eventual necessity of electrification.

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!

Perhaps unsurprisingly, the new Crosstrek looks an awful lot like its a development of the Subaru XV.

Which, given the latter’s popularity, is a very good thing.

While there are a lot of similarities, especially when it comes to some of the more rugged elements, the Crosstrek still manages to look quite new.

It’s rugged without having too many ‘busy’ design elements and it even looks at home in inner-city suburbs. 

Of course, its raised body and cladding are mostly for practical reasons, but it gives the small SUV an adventurous aesthetic that separates it from city-focused rivals.

As essentially a high-riding development of the Impreza hatch, its size and proportions also make it look more like a ‘big car’ than a small SUV.

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.

Practicality is pretty much a staple of Subaru as a brand, so it should be a huge surprise that it feels that way from the driver’s seat.

The interior doesn’t look futuristic, but it does look functional. 

For example, even though the centre of the dash is all screen - and we love buttons for climate controls around here - the controls for air conditioning and temperature are at least always present on the screen, no sub-menus needed.

The phone charger is large enough for even very tall phones (looking at you, Samsung Galaxy S20 Ultra, pictured), and it’s out of the way to minimise extra digital distraction.

The steering wheel’s buttons, while many, are all clear and simple, as is the iPad-like icon layout on the multimedia screen.

Storage in the front is miles ahead of the rear seats, a large central bin with two cupholders, a big glove box, and decent space for water bottles in the door cards. In the rear, two central cupholders in the armrest and a small space in the door.

But there is a decent amount of space for an adult to sit in the rear, even if the sides of the roof are a little close to the head. It’s a little like the front, where the seats are supportive and easy to adjust to a comfortable position.

Further back, the boot space is a relatively small 315 litres, though its slightly larger than the 291L the petrol versions come with - that extra space likely swallowed by a spare tyre in the petrol versions, as opposed to the smaller batteries taking up some space in the hybrids.

When you’re wearing a hybrid badge and you’re up against veterans in the field like Toyota with the Corolla Cross, you want to make sure you’re offering up something substantial.

At $45,090, before on-road costs, the Hybrid S tops the range and comes with a features list that screams it from the rooftops. Or the mountaintops. Or at least as far as the gravel tracks will take you towards the mountaintop.

From the outside, 18-inch wheels are the first indicator for the ‘S’ grade - note that hybrids don’t come with spare wheels, just repair kits - as well as body coloured door handles and black plastic trim and cladding, aside from the gloss mirror caps.

The door mirrors are heated and fold away when parked, while up top there’s a sunroof flanked by roof rails, with a styled spoiler at the rear.

Interestingly, there’s no power tailgate.

LED DRLs and headlights are automatic and are aided by steering responsive active cornering lamps, while the wipers are auto rain-sensing.

Inside, dual-zone climate control and heated front seats (the driver’s is eight-way power adjustable) for the cold - all seats are leather accented - while the steering wheel and shifter are also leather-wrapped.

Tech is covered off by the usual 11.6-inch portrait touchscreen centrepiece, with sat-nav, AM/FM and digital radio, wireless Android Auto and Apple CarPlay, USB-A and USB-C plugs (in the rear, too), a wireless phone charger, and a 10-speaker Harman Kardon sound system over the usual six-speaker set-up. There’s even an auxiliary audio input.

The driver display is a small 4.2-inch unit flanked by physical dials.

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.

This is perhaps the part of the review you’re most interested in - as well as the following sections on efficiency and maybe driving - if the ‘Hybrid’ part of the Crosstrek Hybrid S’ name brought you here.

Like its design and interior, the engine will be familiar to anyone who has owned or driven a relatively recent Subaru - a 2.0-litre flat-four petrol engine good for 110kW/196Nm - which means it makes a little less than the standard petrol variant’s 115kW.

However, the electric motor is capable of its own 12kW/66Nm outputs, though Subaru doesn’t supply a claimed total maximum for the whole powertrain.

Drive is transferred to all four wheels - it is a Subaru after all - via a seven-step continuously variable transmission (CVT).

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.

Subaru claims the Crosstrek Hybrid will sip 6.5L/100km on the combined cycle, which isn’t enough to blow anyone away, even when you take into account the extra fuel needed for permanent all-wheel drive. The AWD Corolla Cross Hybrid comes with a claimed 4.4L/100km.

Compare this to the 8.5L/100km reading the Crosstrek returned after our time with the car, mostly with a (somewhat unkind) mix of inner-city and semi-rural backroad driving, and it’s clear the Crosstrek isn’t one of the most frugal cars in its class.

More highway driving would certainly have lowered the figure - we’ve achieved 8.0-litres on previous testing with a non-hybrid Crosstrek - but perhaps being top of the charts for efficiency isn’t necessarily what Subaru buyers are looking for.

Of course, the Crosstrek Hybrid S employs a couple of features to avoid using fuel where it can be avoided, such as auto stop-start and its (relatively mild) electric system taking over when mostly coasting or the engine isn’t required.

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.

Two things stand out after a short stint behind the wheel of the Crosstrek Hybrid, and both become more cemented over time.

The first is that the ‘Hybrid’ part of the ‘Crosstrek Hybrid S’ isn’t quite as prominent in its real-world impact as it is in its name.

The 110kW engine doesn’t feel like it’s being massively helped along by any electric assistance, and the electric motor is very rarely doing the work by itself, as you’d find in any hybrid from Toyota or Honda.

That’s a shame, because the Crosstrek could do with a little extra oomph, if not for getting up to speed then for avoiding thrashy engine sounds under acceleration.

The CVT, while not necessarily detrimental to its performance, doesn’t help with that.

But balancing that out is a chassis and platform that’s engaging and predictable - and that’s predictable as a good thing - making the Crosstrek pleasant to pilot.

Its controls like steering and braking are nicely weighted for low speeds, commuting, and for more spirited driving, while the suspension and chassis handles surfaces from smooth suburban roads, to city tram tracks, to unsealed roads with ease, soaking up bumps and shakes nicely.

If you’re noticing a theme in this review, it’s that Subaru doesn’t seem to be chasing any ‘best at’ metrics in favour of giving the Crosstrek the ability to do a range of different driving and being at least satisfactory in any given area.

As the range-topper, the Subaru Hybrid S comes with the lot in terms of safety. 

And even though it hasn’t been tested by ANCAP yet, it’d be a shock if its score was anything less than the maximum five stars.

It’s what the XV scored in 2017, and the brand hasn’t missed out on full marks since the Impreza and Foresters of the early 2000s.

Nine airbags include dual front, dual front side, dual curtain, driver's knee, far side, and front passenger seat cushion airbags, plus Subaru’s 'EyeSight' safety suite does the work in crash prevention.

On top of the standard safety features you’d expect from any new car like electronic stability control and ABS, there’s a ‘Pedestrian alert system’, emergency lane keep assist with departure warning and prevention, a ‘Driver Monitoring System’ that includes drowsiness and distraction warnings, sensors and monitors for blind spots and rear cross-traffic, and of course parking sensors.

Some less common features of EyeSight include ‘Lead Vehicle Start Alert’, ‘Pre-Collision Braking System’, ‘Pre-Collision Throttle Management’, ‘Intelligent Speed Limiter’ as well as ‘Speed Sign Recognition’ and ‘Brake Light Recognition’.

Specific to the S, is a surround-view parking camera, high beam assist, plus front- and side-view monitors to help avoid kerbing wheels or bumping towbars.

It’s all fairly well implemented in the Crosstrek, though some of its chimes can be a bit much - the driver distraction alert can mistake a quick climate control change at the lights for a proper lapse of focus, while an alert for approaching speed and red light cameras comes without any indication of what the noise is for.

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.

The Crosstrek is covered by Subaru’s five-year/unlimited kilometre warranty, with servicing intervals coming up every 12 months or 15,000km under Subaru’s five-year capped-price servicing.

Subaru also adds 12 months of free roadside assistance.

This is all fairly standard in the industry, though some brands like Kia and MG offer seven-year warranties, or there’s Mitsubishi with a 10-year warranty (even if it requires certain conditions to be met during the decade).
