Mercedes-Benz C300 vs Subaru Forester

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.

To many people, this review won’t matter. There’s a large part of Subaru’s customer base that come back knowing they’ll get a practical, capable car regardless of refinement - something the brand’s rivals can’t quite match.

But even those people will be pleased to find the new Forester is a huge step-up over the last one in many areas. Sure, it’s a little late for Subaru to be joining the hybrid game in 2025, but it’s not the only brand from Japan that’s been slow on that front, and the brand’s philosophy hasn’t always been focused on efficiency anyway.

In a vacuum, the new Forester is a great adventure companion, but anyone considering a mid-size family SUV and not requiring the AWD and clearance the Forester has on offer could do better elsewhere.

For anyone else, there’s still only one option that really ticks all the boxes - and now it’s much better than before.

Just get the petrol if you’re going anywhere that could damage a tyre.

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!

The new Forester is a slight departure from the characterful previous generation, and to this writer’s eye that’s to its detriment. It’s not unpleasant to look at, but it doesn’t look so much like a Forester anymore.

I wouldn’t be the first to say it looks like it had at least one pass through the North American Ford design centre, but even putting that aside, the rounded front is a less interesting design treatment than we’re used to seeing from Subaru.

Its side profile shows off its boxy, practical nature, however, and from the rear it looks much more Subaru-like than from the front.

In Sport guise, particularly, the Forester’s bronze trim and wheels are a decent give-away that the brand was going for a more premium look.

Inside, the Forester doesn’t look enormously different from the last generation, especially when it comes to buttons, shifters, and the big vertical 11.6-inch touchscreen, the latter right out of other Subaru models that have been around a while.

But perhaps that was deliberate, because some of the new Forester’s best features are those that follow the notion of ‘if it ain’t broke, don’t fix it’.

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.

Perhaps the best selling point for the new Forester is that it hasn’t changed a whole lot inside. It’s spacious for its class and has physical buttons for a lot of things, while making sure the key controls like climate are always accessible on the touchscreen without needing to navigate through menus.

The steering wheel and gearshift look familiar and the general layout of the Forester seems to follow the brand’s established pattern of convenience over anything that could be annoying or complicated.

The software on the big screen is the same as any recent Subaru SUV with big buttons and a simple menu structure that means you rarely get lost. It’s not cutting-edge, but it works, much like a lot of the elements of this car.

The seats are comfortable and the seating position and steering wheel adjustment work well regardless of grade.

One element of the interior that works particularly well is visibility. Subaru made the headrest a little narrower to assist with shoulder checks and make looking over to the back seat easier. The result is a clear view, not only of the interior but also through those annoying side angles your wing mirrors might miss.

The back seat is also plenty spacious, with ample knee, foot and hip room in the second row’s outboard seats. Head and shoulder space is also fab. There’s little risk of feeling cramped in the back, even for a proper adult, especially if there’s a sunroof for that extra light.

Behind the second row, there’s 496 litres of boot space in non-hybrids, and 484L in hybrid variants, plus a switch in the boot to drop the second row from the tailgate.

That allows for 1174L and 1162L in petrol and hybrid models, respectively, though a big downside for the hybrid models is the lack of spare wheel, just a repair kit.

No spare tyre in a car you expect to be able to take off-road isn’t good enough, and it’s the key reason the Forester doesn’t score a full 10 for interior practicality. A shame, because the rest of the cabin is built for ease.

Pricing for the petrol-only Subaru Forester kicks off from $43,490, before on-road costs, putting it north of entry-level variants from rivals like the Mazda CX-5 and Toyota RAV4. It's even a little more expensive than its rivals' cheapest all-wheel drive variants.

The most affordable Nissan X-Trail AWD is $41,065 and the Mitsubishi Outlander AWD is $42,490. Even the cheapest Mazda CX-5, which isn’t an entry trim level, is $42,960.

But what the new Subie has going for it is that even from the base variant it's well-equipped. New 18-inch wheels, auto LED headlights with self-leveling, cornering lamps, roof rails and a front windscreen de-icer make the Forester AWD (its entry variant’s name) ready for a bit of adventuring.

Inside there are cloth seats and it’s got fairly standard trim, but things like dual-zone climate control, heated front seats and electric folding rear seats are all great for comfort and convenience. And a wireless phone charger and big 11.6-inch multimedia touchscreen (with wireless Android Auto and Apple CarPlay) make for an up-to-date list of features for a car in 2025.

There’s also plenty of tech in terms of running gear and safety, which I’ll get to later in the review.

The Forester AWD Hybrid has pretty much the same features, as well as paddles behind the steering wheel to adjust regenerative braking and costs $46,490.

Stepping up a grade, the $46,490 Forester AWD Premium (this grade isn’t available as a hybrid) adds auto-dipping and folding door mirrors and auto door-mirror adjustment to the driver monitoring system, plus there’s a sensor for a hands-free tailgate as well as electrically-adjustable front seats and sat-nav.

The Forester AWD Sport comes in at $48,490, or in AWD Hybrid Sport guise for $54,990, and adds a sunroof, water-repellent seat trim, a digital driver display, green stitching for the steering wheel and a dark metallic set of 18-inch wheels.

Finally, the top-spec AWD Touring costs $50,990 in petrol and $55,990 as a hybrid, with low-profile roof rails, leather-accented seats, a leather gearshifter, ventilated front seats and a 10-speaker Harman Kardon sound system with subwoofer and amplifier.

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.

Both Forester drivetrains use the brand’s existing all-wheel drive tech and a continuously-variable transmission, but the hybrid does something Subaru is keen to point out its rivals’ don’t.

The petrol version is powered by a (136kW/247Nm) 2.5-litre naturally aspirated flat-four ‘boxer’ engine that's largely unchanged.

The hybrid consists of the same type of engine with different valve controls and lower outputs of 121kW/212Nm. 

The key part is it’s assisted by a 90kW electric motor that, rather than being mounted to the rear axle and engaging when traction is needed, is placed before the transmission and sends electric power to all four wheels. Total outputs for the Hybrid variants are 145kW and 276Nm.

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 Forester drinks 7.9L of petrol (minimum 91 RON) per 100km or 6.2L/100km in hybrid guise.

The latter's a bit of a let-down given Toyota’s RAV4 hybrid in AWD guise comes with a 4.8L/100km claim and that system's been around for ages.

Both Foresters have a 63-litre fuel tank, so could theoretically travel a maximum 797km (petrol) or 1016km (hybrid). 

Don’t expect to manage that in real-world driving, though. The trip computer reading for the last car I drove on test (a hybrid) was 7.8L/100km after a mix of highway and off-road running.

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.

On paper, the new Forester hasn’t changed to a great degree. With that engine and the late-ish introduction of a proper hybrid system, you might expect the Forester to be undercooked. 

Sure, Subaru is playing catch-up and it would be a fair to say adding a hybrid grade to its mid-size SUV in 2025 puts it behind the curve, but Subaru is leaning into its niche.

Subaru’s very happy about being able to claim the Forester is the only hybrid mid-size SUV on sale where the one hybrid motor drives all four wheels mechanically thanks to its 'symmetrical' all-wheel drive system. Then there’s the "class-leading" 220mm of ground clearance.

But as well as being capable off the road, the Forester needs to be a decent day-to-day companion. Fortunately, it’s both.

The new Forester’s road manners are a surprising step-up over the previous generation’s, which felt soft and agricultural at times.

Subaru touted the new car's incremental improvements, but behind the wheel it feels like they add up to a far superior experience. The Forester is still a little noisy - mainly wind and road noise - but many of the elements that were once a let-down are much more refined.

The CVT doesn't complain so much when called upon to pick up the pace, and the steering feels much sharper. The former could be down to a huge increase in sound-shielding, the latter likely due to Subaru’s use of the dual-pinion steering system borrowed from the WRX.

Subaru says it “reduces mechanical resistance and eliminates unwanted feedback from the motor”. It seems to have done exactly that.

Perhaps most noticeable is the suspension, which feels more tied-down and stable than before, without sharpening up too much and becoming uncomfortable. Subaru says revised spring rates, better under-body aero and a more rigid chassis all contribute.

The hybrid and petrol have different suspension set-ups, the latter feeling softer in terms of damper response but still far more confidence-inspiring than the previous-gen Forester.

It all comes together to create a driving experience that’s easy and comfortable at traffic speeds and fun and engaging at high speeds on, for example, the smooth winding back-roads of New Zealand’s South Island.

The problem for Subaru is that despite having introduced a new hybrid system, the petrol-only Forester is just as good from behind the wheel. The advantages the hybrid brings in terms of efficiency will be a draw for some, but in terms of driving dynamics the extra power and torque on offer is probably not worth the extra outlay.

Then there’s the lack of a spare wheel… which should be a requirement when you’re off sealed roads. The gravel and mud of the Canterbury region didn’t faze the Forester, though, and we put the mid-size SUV through its paces harder than most owners realistically would.

Deep mud ruts, creek crossings and jagged rocky trails were all traversed easily and comfortably, especially considering the standard road tyres fitted. 

None of the test cars were stuck due to either negligent road testers or lack of mechanical ability on the Subaru’s part, though two cars on test did succumb to an excess of water in the engine bay and went into a safety shut-down mode once we arrived back at the end of the off-road trail.

We asked Subaru for an explanation and we were told it’s a feature that saves components like the cooling fan from water damage.

“Two vehicles experienced this due to the nose being submerged from entering the water crossing at the incorrect speed and/or entry line… if water enters the engine bay at a sufficient level, a protective fuse is designed to engage to safeguard the radiator fan motor.

“This system functioned exactly as designed. Despite this, the vehicle continued to perform as intended, enabling the driver to complete the off-road course and return safely to the Homestead. 

“After cycling the ignition, a warning light alerted the driver, and the engine shut down automatically to prevent any potential damage. This sequence is outlined in the Owner’s Manual. This is a built-in protection protocol and not a fault.”

A replacement fuse meant one of the vehicles “resumed full operation,” a Subaru spokesperson added.

A maximum five-star ANCAP rating and nine airbags (dual front, dual front side, dual curtain, driver’s knee, far side and front passenger seat cushion) should all mean peace-of mind in case of the worst, but Subaru also has a long list of safety features to avoid that being necessary.

The brand’s 'EyeSight' safety suite features adaptive cruise, emergency lane-keep and centering with departure warnings, pre-collision braking and auto emergency steering, brake light recognition as well as speed and sign recognition, plus there’s a driver monitoring system and a series of radar and cameras that allow for a surround-view of the car.

The Forester also has a feature Subaru is very proud of, which detects a lack of response from the driver via inputs, and gradually tries to wake or alert the driver through sounds and gentle jolts via braking before eventually coming to a safe stop and unlocking the doors to allow assistance.

To Subaru’s credit, this all features on every variant.

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‘s five-year, unlimited kilometre warranty is behind the curve for mainstream brands with many offering between seven and 10 years, but its eight-year/160,000 kilometre hybrid high-voltage battery warranty is par for the course.

Servicing intervals are every 15,000km or 12 months, with servicing pricing locked in for the first 75,000km or 60 months of ownership. Total cost over this time is $2299 for either drivetrain, with the cheapest service being $347.95 and the most expensive $679.30 (at 60,000km or 48 months).

Subaru also offers 12-months complimentary roadside assistance.
