Mercedes-Benz C300 vs Aston Martin Vantage

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 either a comfortable race car or a bonkers grand tourer, but it’s that best-of-both worlds positioning that makes this new Vantage so appealing. Think of it as like a supercar for proper grown-ups, and one you don’t need to grunt and groan to extract yourself from.

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!

Ok, so the first thing you notice is this massive grille, which I now know is exactly 38 per cent bigger than before. That’s mostly for cooling, sucking in great lung-fulls of air – and any stray pets unlucky enough to wander into its path, I’d imagine — to keep that engine humming.

That air has to go somewhere, and the new bonnet vents complete the engine-cooling.picture.

Then there are 21-inch alloys are wrapped in performance rubber, and I love the swollen haunches at the rear tyres, giving the Vantage a mean and menacing vibe. At the rear, a very new and very loud quad-exhaust completes the picture.

In the cabin you'll find nothing in the way of hand-me-down Mercedes switchgear, which makes for change. This is all Aston Martin, and actually it all feels really nice.

The twin-screen setup looks tech-savvy and premium, the materials are all nicer than you'd find in something more track-obsessed, and even the optional race seats managed to be both snug-fitting and comfortable.

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.

You’ll be shocked to hear that Aston Martin didn’t dedicate too much of its limited track time to extolling the practicality perks of its new Vantage, mostly because there simply aren’t that many of them.

But the most obvious one, I think, is that most of the people in the market for a $400k-plus vehicle in this category are likely to be, well, of a certain vintage, and it’s for these people that the more traditional layout of the Vantage will no doubt appeal.

See, the engine is up front, and the doors open in the usual fashion, making getting in and out of the cabin easy, and free of the human-origami antics sometimes required to climb in and out of a scissor-door supercar.

But there have been practical improvements made to performance here, too. There’s 30 per cent more power, 15 per cent more torque, new cooling, better aerodynamics, retuned suspension and anti-roll tech, new brake booster tuning, improvements to the ESP system, more body stiffness. And it goes on.

Let’s start with the big number, and that is the $410,000 you’ll need to park the new Vantage on your driveway. Interestingly, I was also on the launch of the previous Vantage, back in 2018, and that one was just under $300k. That’s quite the jump.

Anyway, for that spend you get a whole bunch of improved performance, obviously, but also quite a bit in terms of cabin tech and comfort. This isn’t a stripped-back supercar, and that’s a good thing, I reckon.

It starts outside with 21-inch five-spoke forged wheels wrapped in Michelin Pilot Sport rubber, matrix LED headlights and LED tail-lights, while in the cabin, there’s a 10.25-inch central screen with Apple CarPlay, a second 10.25-inch screen in front of the driver, an 11-speaker stereo, and wireless phone charging.

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 4.0-litre twin-turbo V8 is still borrowed from Mercedes-AMG, but this is the new-generation unit, making 489kW and 800Nm. It gets modified cylinder heads and bigger turbos, helping generate the extra grunt.

That’s fed through an eight-speed ZF automatic and channeled through to the rear tyres. The race to 100km/h? That 3.5 seconds. Meanwhile, the flying top speed is around 325km/h.

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.

There’s the official figure, which is 12.1L/100km on the combined cycle, and then there’s the real-world figure. It’s not really fare to judge fuel use when you’ve just stepped off a racetrack, but rest assured it was a large number, which is to be expected really.

The Aston’s 73-litre fuel tank prefers 98RON fuel, too.

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.

It's funny, I never felt like the old Vantage wanted for power, but now I suddenly wonder how we ever made do with it. This feels like the engine and the outputs that should have always been, such is the way it suits the nature of Aston’s most performance-focused model.

Everything is about the driver here. From the suspension tune to the gearbox mapping and the increase in stiffness everywhere. You’re supposed to feel like the main character, and you do.

Aston Martin have come under fire in the past for delivering cars that are a treat to look at, but didn't quite deliver the drive experience to match the appearance, and it's something the brand says it is actively rectifying with with the Vantage, and the Astons that will follow it.

The mission, it says, is to be spoken of in the same sentence as the Italian supercar makers when it comes to delivering driver engagement, and this 2024 Vantage is a considerable leap in that direction.

It is, above all else, fun. From the multi-stage ESP settings that you can pair to your bravery, to the retuned and raucous exhaust and the blistering acceleration.

More than that, it feels light and lithe on a racetrack, and super communicative, the front wheels talking through your wrists, and the back tyres through, well, the bit of you that hits the bottom half of the racing seat...

It is plenty fun, right across the park. The power is immense, but somehow it doesn't feel terrifying, partly because you're so dialled-in to the drive experience, and partly because the carbon brakes fitted to our test car were able to slow the Vantage so savagely it's as though we'd dropped anchor out the back window.

The Vantage does have a split personality, though, and it's one that really shows itself once you venture out onto the road. It's quiet, comfortable even, at suburban speeds, leaning more into grand tourer than bonkers track-day special.

The only downside being that, should you sit behind the wheel long enough, it becomes easy to forget you're driving something "super" at all. Well, until your right foot finds its way back to the accelerator, that is...

You’ll never see a Vantage crash-tested by ANCAP, but it does arrive with a solid safety package.

There are front and side airbags, plus a heap of active safety stuff like AEB, forward collision warning, adaptive cruise, lane keep assist, lane departure warning, lane change assist with centring and front and rear cross-traffic alert.

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.

Aston Martins in Australia are covered by a three-year/unlimited-kilometre warranty, but you can extend that for one or two years, at a price.  You’ll be visiting the service centre annually, too.
