Mercedes-Benz C300 vs Volkswagen Passat

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.

I so enjoyed driving the Volkswagen Passat 206TSI R-Line. It's a roomy wagon that should fit a lot of different types of families. It still has sporty performance that will entice even the most reluctant family car buyer, so don't be turned off by its large proportions! I really like the comfort, convenience and handling of this one, so it gets an easy 8.0/10 from me.

My kid thought the blue colour was cool and loved having so many things to play with in the back seat. His only complaint was about the heavier doors but he still managed. He gives it an 8.0/10, too.

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 Passat is a large car and stands at 4708mm long, 1832mm wide and 1504mm high. The boxier rear and long nose make these proportions feel even larger.

The 2023 model doesn't see much change, if any, to the previous iteration. The exterior features the classic VW sharp pleat that runs the length of the body, slim-line LED lights and pronounce grille with lots of chrome accents found throughout.

It looks shiny, new and stylish, but not garish. You'd be proud to be seen in this.

The interior is also classically VW – sharp, a little pared back and hosting easy to see buttons and dials. The adjustable ambient lighting elevates the cabin space, as does the black headliner (R-Line exclusive).

An interesting feature is the directional air vents, the slatted design is carried the entire length of the dash which accentuates the width of the car. It all looks seamless and well thought out.

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.

A very practical family wagon with all passengers enjoying ample head and legroom.

The amenities in both rows are very good. The seats are fairly comfortable but the lumbar support isn't awesome. The massage function on the driver's side is a nice novelty but not strong enough to be called a massage. Think of it as gently stretching.

For storage, you get a decently sized middle console, dedicated phone tray, cooled glove box, drink bottle holders in each door and two cupholders.

There are plenty of charging options available for the front with two USB-C ports and a 12-volt socket. Bonus having the wireless Apple CarPlay (and Android Auto), as it's one less cable you have to worry about.

In general, I like how easy the tech is to use. The 9.2-inch touchscreen multimedia system looks great and is responsive.

It's easy to get all the connections going and you can pull the built-in satellite navigation directions through to the 10.25-inch digital instrument panel. I did miss having a head-up display this week but the info on the instrument panel is displayed clearly.

The back seat gets a couple of cupholders in the fold-down armrest and drink bottle holders in each door. It also has directional air vents with climate control, reading lights and one USB-C port for charging. However, I would have liked to have seen another charging port, to limit sibling squabbles.

There are ISOFIX child seat mounts on the outboard seats plus three top tether anchor points.

The backseat is wide enough to fit three child seats side by side if needed, and there's plenty of room for front passengers when a 0-4 rearward facing child seat is installed.

The windows are wide and offer good visibility but I really like the 142mm ground clearance. It was super easy for my six-year old to climb in and out.

The only thing he mentioned he didn't like was how heavy the doors were to operate. I don't mind this because they feel solid but they do swing wide, so be wary of letting any wild kids just hop out themselves in a crowded car park. You may get (or inflict) some dings.

The boot is a great size at 650L, with all seats in use, but if you pop down the backseats, that jumps up to 1780L.

The back seat also split-folds 40/20/40, which opens up your storage options. I enjoyed using the powered tailgate with kick function, it's handy on the grocery run.

The 206 TSI R-Line is top of a (small) two-model line-up. Our example has been finished in 'Lapiz Blue', a colour exclusive to the R-Line. Otherwise, expect a sea of monochromatic colour options.

We say top model but it's not necessarily a massive jump up in specifications from the 162 TSI Elegance, you're paying for the engine performance on this one.

This R-Line will cost you $67,790, before on-road costs. That's a $4K price hike from the 2022 model with no discernible upgrades.

And that price tag still puts it well above its closest rivals, with the Octavia RS 180 TSI being $53,090 and the Mazda6 Atenza at $52,140 (all before on-road costs).

However, you won't be disappointed with the features list with Nappa leather-appointed seat trim, R-Line stitched detailing on the floor mats and seats, electric and heated front seats, massage function on the driver's seat, a panoramic sunroof as well as wireless Apple CarPlay and Android Auto all coming as standard.

The R-Line also enjoys 19-inch alloy wheels, a full-sized spare, heat insulating tinted glass, 65 per cent light reducing rear privacy glass and 30-way adjustable ambient lighting in the cabin.

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.

The R-Line has a 2.0-litre, four-cylinder turbo-petrol powertrain with a maximum output of 206kW/350Nm.

That puts its engine specs 44kW up on the Elegance model and you feel that difference when you put your foot down.

The six-speed auto transmission provides surprisingly smooth shifting in most settings. The grunty engine combined with the all-wheel drive creates a sporty and purposeful driving experience.

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.

That powerful engine does cost you a little bit with efficiency. The official combined fuel figure is 8.1L/100km and real-world testing saw my figure at 8.6L.

Not too bad for the type of driving I did this week, which was a combo of open-road and urban. I wasn't scared of putting my foot down but I would expect to see a double-digit figure in an urban setting.

This has a 66L fuel tank and based on the official combined figure, you should be able to get around 815km driving range, which is great.

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 performance of this is to be commended. Powerful but poised, there's a sense of performance in reserve when you put your foot down and while still fun, it's not unbridled power.

It inspires confidence, the lower centre of gravity and firm steering meaning you tackle corners with minimum roll. You can accelerate out of a corner a little earlier than you might normally in this.

The cabin is nice and quiet with some road noise at higher speeds but not enough to intrude on chatting.

Despite suspension that feels sporty, aka stiff, the ride comfort is very good, with back seat passengers also feeling the comfort. There's not a lot of jostling in this.

Let's talk parking. It is a large car but you don't feel those dimensions when you park it.

It's very forgiving to manoeuvre with the front and rear parking sensors, crisp 360-degree view camera and tight 11.7m turning circle!

And if you're not confident it has a self-parking feature.

This has a good list of safety features with the following being standard: LED daytime running lights, lane departure alert, lane keeping aid, blind-spot monitoring, rear cross-traffic alert, 360-degree view reversing camera with dynamic guidelines, front and rear parking sensors, driver fatigue alert, and adaptive cruise control (with stop/go function).

I like the Emergency Assist feature which will provide multiple visual and sound alerts if there's no steering wheel activity detected. If there's still no driver input, the car will slow down and ultimately come to a complete stop.

The Passat's maximum five-star ANCAP safety rating has just expired and at the time of writing was yet to be retested.

The 2023 Passat has nine airbags, including side airbags for the rear outboard seats, as well as curtain airbags covering both rows.

There are three top tethers across the rear row and ISOFIX child seat mounts on the outboard positions.

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 Passat comes with a market standard five-year/unlimited km warranty, and roadside assistance is included for one year (through Allianz Insurance) if you get your car serviced at a VW centre.

There is a three- or five-year capped price servicing plan that can be pre-purchased and will save you money compared to the pay-as-you go option. Servicing averages $620 though, which is expensive for the class.

Servicing intervals are reasonable at every 12 months or 16,500km – whichever occurs first.
