Mercedes-Benz C300 vs Subaru Outback

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.

Over 30 years and seven generations of Outback in Australia, the latest might just be the best.

It's great to drive, even better to sit in, very easy to live and willing to go further than most equivalent large SUVs at its price point.

The styling is definitely divisive, with purists unhappy that the long, crossover wagon silhouette is now gone, but what we have instead is a family-friendly vehicle that pleases on so many fronts.

We’d go as far as saying the latest Outback might be the most-rounded Subaru currently available, and great value to boot. And the base AWD is all the SUV most people will ever need.

That’s not bad for something this square!

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!

Historically, Subarus have majored on quirky. Kooky even.

Think buggy ‘60s 360, offbeat ‘70s 1400, spacey ‘80s Vortex, futuristic ‘90s SVX, Alfa-esque ‘00s pre-facelift Tribeca, dorky ‘10s Exiga. We’d go as far as saying that, in over 50 years, only a handful of Subarus have looked normal. And they’ve all been boring. The beautiful ones, like the original Impreza and ’03 Liberty, remain stunning.

But quirkifying such an important family car in such a mainstream segment… that's risky. And we’re here for Subaru’s boldness. We just wish the details weren’t so heavy handed.

Longer, larger and wider than any prior version, the 2026 Outback shares its stretched platform architecture fundamentals with the latest Forester. That’s a sound basis. Just Xeroxed up by about 15 per cent. Boxy shape. Deep glass. Wide doors. Form over function. This is designed to make life easier.

What you make of the Wilderness’ visual features, including the dramatic grille mask, SUBARU wording, painted trim surrounds and cladding-on-cladding (behold the Kia Tasman-like squared-off wheel arches if you dare) is down to personal taste. Eyes be damned! But it is so far-removed from the elegant grace of the previous model that some might argue a name change would at least have silenced the critics.

On the other hand, besides fugly being in Subaru’s DNA, a large, lofty SUV is probably truer to the term ‘outback’ than on any elegant and gracefully-silhouetted crossover wagon.

Meanwhile, the polar opposite is true inside. It’s as if the interior designers strove for class and calm, with none of the exterior styling’s visual noise, or shouting in the Wilderness’ case. And there is the luxury of space, vision and scope, further enhancing the Outback’s usefulness. That you can’t see the body, just the beautiful cabin’s detailing, elevates this Subaru. Unlike in the previous model, which was a bit of an aesthetic and functional mess inside.

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.

Like all Subarus, Outback boasts an interior of very high-quality craftsmanship, being built beautifully, without rattles or noises or jarring trim.

The difference here is just how pleasingly practical and easy yet attractive this environment is, from the moment that wide-opening door opens and shuts with reassuring solidity.

The horizontal dash layout departs from the Tesla-aping portrait screen domination of the previous generation, banishing the confusing and annoying virtual controls for real, live buttons.

But is it original? The layered presentation is attractive and distinctively Toyota… err Subaru. Yes, it is very much like the bZ4X-based Solterra EV’s look inside.

That’s no bad thing from an ergonomic point of view. The driving position is flawless, the seat/wheel/controls relationship considered and the placement of the climate controls, audio system, armrest and storage just right. We’re also happy to see the instrumentation display incorporate various visual choices, including digital analogue-style dials.

A particular callout goes to the slick and speedy tactility of the brand’s latest touchscreen, as well as the (again suspiciously Toyota-like) interface and graphics layout. It’s all good.

But wait, there’s more. The Outback’s front seats are claimed to be particularly supportive, and after hours in them on and off road, they seem to exceed Subaru’s claims.

If you’re expecting regular mid-sized SUV levels of interior space, be prepared to be impressed, because the Outback’s extra sizing outside seems to be multiplied inside. There’s ample room for long legs, big hats, broad shoulders and buxom hips. It all works so well. This is probably one of the best modern SUV interiors, period. Nothing seems to have been overlooked.

The rear seat is presented to please, too. It can seem a bit drab in the lower-line models, but the same virtues of effortless entry/egress, seat comfort, convenience (including air vents, USB ports, cupholders and armrest placement) apply. We noted the lack of road/tyre noise intrusion at speed, too.

Behind the very sixties Jeep Wagoneer-looking rear is a vast luggage area, complete with a low floor, remote rear-seat folding handles, 12V outlet and quality trim. And that space-saver spare lives underneath.

Subaru seems to have designed this car from the inside out and it shows. A rare 10/10 from us.

Bad news first. Model-for-model, each Outback grade is now up around 10 per cent compared to the preceding, more petite and prettier version.

This means the cheapest of the five grades available, known simply as AWD (for all-wheel drive – this seems almost redundant for a non-BRZ Subaru), now kicks off from $48,990. All prices here are before on-road costs.

This includes a proper off-road mode, climate control, synthetic leather trim, a 12.1-inch multimedia touchscreen, 12.3-inch electronic driver display, wireless Apple CarPlay and Android Auto, a powered tailgate, heated front seats with powered driver’s side, chunky roof rails, 18-inch alloy wheels (with a space-saver spare – thank you, Subaru), nine airbags and comprehensive Advanced Driver Assist Systems (ADAS). Check out the safety section further down for more details.

Notes for the facelift, Subaru: Why can’t the base grade come with cloth, rather than clammy vinyl seats?

Next is the AWD Premium. From $53,490, that’s a reasonable ask given its 360-degree-view monitor, sunroof, heated steering wheel, powered front passenger seat and 12-speaker Harman Kardon audio upgrade.

The $56,990 AWD Touring includes Nappa leather, ventilated front seats, heated outboard rear seats, a wireless charger, active lane change, auto-fold mirrors with self-dipping in reverse (c’mon, this should be standard) and glossier alloys.

From here, we’re in new Wilderness territory. Two grades, AWD Wilderness from $59,690, adding more cladding upon cladding, a turbo engine, electronic dampers, 20mm extra ride height, broader 'X-Mode' off-road functionality, a wireless charger, claimed water-repellent seat trim, different fog lights, black-finish alloys and more.

But, strangely, you lose the sunroof, sat-nav, 360-degree view monitor and premium audio. Subaru demand another $3.0K to restore these in the flagship AWD Wilderness Apex from $62,690.

Still no cloth option, though. We’d like a new base AWD grade with the Wilderness mechanical gear and stance but not the extraneous cladding and visuals, and with coarse fabric upholstery, manual option and steel wheels. Maybe call it Leonie for fun.

Anyway, does new Outback represent value for money? One of its main rivals in the sparsely-populated five-seater large SUV class (most have three rows) is the Mazda CX-60. The AWD slots nicely between the slightly cheaper but very basic four-cylinder RWD Pure yet undercuts the much-sweeter six-cylinder AWD version, so we’d answer that with a yes.

Furthermore, when you tally up all that extra stuff, size and space, today’s out-stretched Outback offers comfortably more over the old model than that modest 10 per cent price hike suggests. That’s a win for buyers.

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.

Don’t worry, Subaru traditionalists. The Outback again offers a pair of horizontally-opposed 'boxer' four-cylinder engines.

The regular Outback versions are powered by a 2.5-litre twin-cam petrol unit making 137kW of power at 5800rpm and 254Nm of torque at 3700rpm.

Choosing the Wilderness switches things up to a 2.4-litre turbo version delivering 194kW at 5600rpm and 382Nm between 2000rpm and 3600rpm.

Both use a continuously variable transmission (CVT) with eight artificial ‘steps’ for a more torque-converter-like experience. Sadly, no manual gearbox is available.

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.

Where the Outback regresses compared to its predecessor is efficiency.

Despite a modest 50kg weight rise, the substantially boxier shape is probably behind the jump in petrol consumption, rising nearly one litre per 100km compared to before in the Outback, and nearly 2.5L/100km, in the heavier Wilderness.

The combined average consumption figure for the 2.5-litre naturally aspirated engine is 8.1L/100km, for a carbon dioxide emissions rating of 183 grams per kilometre, while the 2.4-litre turbo manages 9.7L/100km and 228g/km.

Filling the 63L tank, expect an average range of about 777km in the former and just 648km in the latter. Surely, the coming hybrid version can’t arrive soon enough for some buyers.

At least both engines can drink from the standard 91 RON petrol bowser.

So much for the theory. Out in the real world, over a solid day's testing on- and off-road, we found there was a difference of about 1.5L/100km between the regular Outback and the Wilderness.

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.

Confession time. The way the previous Outback drove was profoundly disappointing. The steering felt numb, the ride was too stiff and the car seemed wilfully dull, even in the turbo version.

The contemporary Forester ran rings around it for driving pleasure and refinement.

But Outback number seven is completely different and maybe the best-driving non-WRX Subaru right now.

From the moment you climb on board this vast SUV from Japan, everything feels right – from the driving position and relationship with the controls, to the sumptuously comfy seats and commanding vision all around the vehicle. That’s a promising start.

Push the ignition and press the accelerator down, and the regular Outback 2.5 quietly, gently and smoothly moves off the line. With modest power outputs and a CVT, you might expect it to also sound revvy and droney, but instead the acceleration is strong and throttle responses determined.

We drove this for hundreds of kilometres and never found the performance lacking, even with three adults and their luggage on board, over hilly and even mountainous terrain. Yes, it is possible to have the CVT whining at higher revs, but not within normal driving scenarios. And the quietness and lack of road noise is terrific.

Moving to the Wilderness and its 2.4-litre turbo powertrain, the same applies, except of course mid-range response is significantly faster and with a slicker, more refined delivery. Press and squirt, this is deceptively quick, because the car does a great job in masking the noises and vibrations that working an SUV hard often elicit.

We only wish there was a manual option. With steel wheels, cloth seats and without the Wilderness' add-on gargoyles.

Now, it also seems that Subaru listened and learned from previous criticisms like ours, because the Outback’s newly-redesigned steering is a delight, with a natural, fluent sweetness and ease that’s combined with a pleasing connection with the driver.

The result is balanced, controlled and enjoyable handling, backed up by reassuringly stable road holding. We drove through a sudden, heavy thunderstorm near Bathurst on the first, hot summer afternoon’s test session, and found the Outback to feel impervious through such slippery conditions.

And this all largely applies to the Wilderness as well, though its 20mm-higher ground clearance (to 240mm) makes it feel a little less composed than the glued-down regular model. Both feature a stiffened body and multi-link rear suspension, by the way.

More progress has been made in the Subaru’s ride quality. Gone is the hard suspension feel, for a far-less firm set-up, providing a comfortable and queasy-free ride. Even in the loftier Wilderness. This is the model’s greatest advance over its predecessor and we’re extremely happy with the outcome.

Finally, other than the at-times over-eager driver-attention monitor, the ADAS tech provides subtle, nuanced back-up, with quiet lane-keep intervention, a measured adaptive cruise-control functionality and no jarring buzzes and warnings.

We also enjoyed a session taking both grades off road, to show off their 4WD prowess. The clearances are ample, the hill-descent tech effective and the ability to scramble over wet rocks impressive. The Wilderness especially may even live up to its name!

This is a difficult SUV to fault. The Outback’s breadth of capability on and off the beaten track give it an unusually wide bandwidth for what is a monocoque bodied family convenience. That there is so much sophistication and fun to be had as well make this so much better to drive and live with than the disappointing old version.

We can’t wait to get to know the latest Subaru better on more familiar roads.

There is no ANCAP crash-test rating at the time of publishing, but anything less than the full five stars will come as a scandalous shock from Subaru.

The Outback’s aforementioned ADAS tech runs to AEB front and rear, rear cross-traffic alert, blind-spot monitoring, emergency lane-keep assist, lane-departure warning/prevention, a pre-collision braking system, adaptive cruise control with full stop/go functionality across all grades. Also present are traffic-sign recognition and new acceleration override tech to help prevent collision. Nine airbags are fitted, while a front-centre airbag is new to the series.

No AEB performance parameter information has been released as yet for Australian models.

Finally, there are two outboard rear-seat ISOFIX child restraint points and two top tethers available.

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.

Subaru offers a five-year/unlimited kilometre warranty, and that also comes with 12 months of roadside assistance.

Now, that's pretty average nowadays, so nothing special, particularly when other SUV companies like Mitsubishi, Nissan and MG offer conditional 10-year warranties.

Service intervals are at 12 months or 15,000km for both engines. There is a capped-price servicing offer covering this timeframe. They are currently listed at approximately $350, $530, $405, $705 and $370 for an average of $472 per workshop visit.

There are 128 dealers or authorised Subaru service centres across Australia as of January 1, 2026.
