Mercedes-Benz C300 vs Honda Odyssey

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.

The Honda Odyssey isn’t a bad choice for those looking to ferry around a large gaggle of people, but its far from the best option.

The first two rows are great and are supremely comfortable for those four occupants, but third-row usage will depend on how much those passengers are susceptible to motion sickness.

However, the Odyssey’s biggest weakness might be its sluggish engine and mundane CVT, with rivals like the new Kia Carnival and even Toyota Prius V offering better performance and better economy, respectively.

Still, the Honda Odyssey, and people movers in general, remain a solid option for those that don’t want another SUV or value the practicality and space afforded.

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!

Gone are the days where people movers could be considered daggy or uncool. No, please, don’t click away, we’re serious!

The 2021 Honda Odyssey features a new front grille, bumper and headlights that combine for a much more imposing and aggressive front fascia.

The chrome highlights look especially good against the 'Obsidian Blue' paintwork of our test car, at least to our eyes, and between this and the new Kia Carnival, people movers might just be cool again.

In profile, the 17-inch wheels do look a little small next to the massive doors and huge panels, but they do feature a funky two-tone look.

The chrome touches also follow along the Odyssey’s flanks and are found in the door handles and window surrounds to break things up a bit.

From the rear, the Odyssey’s large dimensions are hard to hide, but Honda has tried to jazz things up with a roof-mounted rear spoiler and more chrome around the tail-lights and rear fog light surrounds.

Overall, the Odyssey looks handsome and confident without straying into the ‘trying too hard’ or ‘over the top’ territory, and if anything, at least it’s not another high-riding SUV, which are quickly overtaking streets and car parks the world over.

Step inside and the Odyssey’s layout is nothing special, but gets the job done.

The first- and second-row seats are plush and comfortable, while the dashboard also features woodgrain touches to lift the interior ambience.

The 8.0-inch multimedia screen sit proudly in the centre stack, while the shifter is on the dashboard to maximum interior space.

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.

Measuring 4855mm long, 1820mm wide, 1710mm tall and with a 2900mm wheelbase, the Honda Odyssey is not just an imposing behemoth on the outside, but also a spacious and practical people mover on the inside.

Up front, occupants are treated to plush and comfortable seats with electronic adjustment and individual fold-down armrests.

Storage options abound, with deep door pockets, a dual-chamber glove box, and a tricked-out centre storage console that can retract into the centre stack and features two hidden cupholders.

Because of the compact engine and transmission package, and the fact the centre console tucks away, there is actually just empty space between the two front occupants, which is a missed opportunity.

Maybe Honda could have put another storage bin there, or even a cooled box for chilled drinks on long road trips. Either way it’s a notable, unexploited cavity.

The second-row seats are probably the place to be in the Odyssey, though, with its two captain’s chairs offering supreme comfort.

Adjustability is also plentiful, with forward/backwards, recline and even left/right positioning available.

However, while there are cupholders and roof-mounted climate controls present, there really isn’t much else to keep second-row occupants, well, occupied.

Would be nice to see some charging ports or even entertainment screens to keep kids and adults placated on long journeys, but at least the head, shoulder, and legroom is generous.

In the third row, it’s a tighter squeeze, but I managed to get my 183cm (6'0") frame comfortable.

The three-row bench is the least comfy place to be, but there is a charging outlet and cupholders back there.

Those with child seats also take note, the second-row captain’s chairs top-tether anchor point is very low down on the seat back, meaning you might have to max out the strap length to get it there.

Also, because of the captain’s chairs, the top tether strap can be knocked off quite easily, as the inner shoulders of the seats are smooth offering nothing for the strap to catch onto if pushed towards the middle of the car.

And you can’t even install the car seat in the third row because the bench seat doesn’t feature any ISOFIX points. 

With all seats in place, the boot will happily swallow 322 litres (VDA) of volume, more than enough for groceries, school bags or even the stroller.

However, the boot floor is quite deep, making the retrieval of bulkier and heavy items a little cumbersome.

With the third-row folded, though, that cavity is filled in and the Odyssey features a completely flat floor then able to take on 1725L of volume.

Honda has even found a place for the space saver spare wheel, though it’s not underneath the car or tucked into the boot floor as you'd expect.

The spare is under the two front seats, and requires the removal of some interior carpets and trim to access. 

It’s not in the most convenient of places, but props to Honda for getting one in there when other seven-seaters just opt for a puncture repair kit. 

The 2021 Honda Odyssey range kicks off at $44,250, before on-road costs for the base Vi L7, and extends to $51,150 for the top-spec Vi LX7, which we have here.

Compared with the likes of the Kia Carnival (from $46,880) and van-based Toyota Granvia (from $64,090), the Honda Odyssey is more affordable, but doesn’t skimp on equipment to bring its price down.

As standard, the 2021 Odyssey is fitted with 17-inch alloys, keyless entry, push-button start, second- and third-row air vents, and a powered rear passenger door, while new for this year’s update is a 7.0-inch customisable tachometer, fresh leather-wrapped steering wheel and LED headlights. 

Handling multimedia duties is a new 8.0-inch touchscreen with Apple CarPlay and Android Auto functionality, as well as Bluetooth connectivity and a USB input.

Stepping up to the top-spec Vi LX7 nets buyers tri-zone climate control with second-row controls, powered tailgate, gesture controls to open/close both rear doors, heated front seats, a sunroof and satellite navigation.

It’s a good list of equipment, but there are some notable omissions such as a wireless smartphone charger and rain-sensing wipers, while the handbrake is one of those old-school foot-operated ones, which is a shame to see in 2021.

Nevertheless, even the top-spec Vi LX7 we have on test here is still relative affordable compared to rivals, and offers plenty of space for the price.

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.

All 2021 Honda Odysseys are powered by a 129kW/225Nm 2.4-litre ‘K24W’ four-cylinder petrol engine, which drives the front wheels via a continuously variable automatic transmission (CVT).

Peak power is available at 6200rpm, while maximum torque is on stream from 4000rpm.

Honda diehards might note the K24 engine designation and be reminded of the rev-hungry 2.4-litre unit of the Accord Euro from the early 2000s, but this Odyssey’s powerplant is built for efficiency rather than performance.

Compared to the likes of the Kia Carnival (which is available with a 216kW/355Nm 3.5-litre V6 or 148kW/440Nm 2.2-litre turbo-diesel) the Odyssey is noticeably down on power.

The Australian Odyssey also doesn’t feature any form of electrification, such as the Toyota Prius V, which would excuse the lower outputs and push the Honda people mover more into green territory.

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.

The 2021 Honda Odyssey, regardless of grade, will return a fuel consumption figure of 8.0 litres per 100km, according to official figures.

This betters the fuel economy of the petrol-powered Kia Carnival (9.6L/100km), as well as the Mazda CX-8 (8.1L/100km) and soon-to-be-replaced Toyota Kluger (9.1-9.5L/100km).

In our week with the Odyssey Vi LX7, we managed an average of 9.4L/100km in a mix of inner-city and freeway driving, which isn’t too far off the official figure.

Though the fuel consumption isn’t too bad for a naturally aspirated petrol engine, those who want to save costs at the bowser should look to the petrol-electric Toyota Prius V hybrid, which sips just 4.4L/100km.

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.

Though the Honda Odyssey looks like a bus on the outside, it doesn’t feel like one behind the wheel.

The Odyssey drives differently to an SUV, which is a good thing, feeling more hunkered down and connected to the road compared to the wallowy and bouncy nature of some high-riders.

Don’t get me wrong, this isn’t Honda’s best handling model, but there is certainly enough feedback in the steering wheel to know exactly what’s happening underneath, and the Odyssey always feels predictable, regardless of road condition.

And because visibility is excellent all around, the Honda Odyssey is just an easy, no-fuss car to drive.

The second-row is also great while on the move, and might actually be the better place to be.

The seats do a great job at soaking up little bumps and road imperfections, and there is plenty of room to stretch out and relax while someone else handles driving duties.

It’s a shame, then, that there isn’t more going on in the second row to keep passengers happy.

The third-row seats, though, are nowhere near as comfortable.

Maybe it’s the fact they are positioned right over the rear axle, or it’s the thick and vision-obscuring C- and D-pillars – or a combination of both – but time in seats five, six and seven, aren't ideal for those prone to motion sickness.

Maybe kids, or those with stronger stomachs can get comfortable in the third row, but for us, it was not a pleasant experience.

The 2021 Honda Odyssey wears a maximum five-star ANCAP safety rating from its test in 2014, as the current model is a heavily revised version of the fifth-generation car that launched seven years ago.

While back then the Odyssey did not come with advanced safety features, a key part the model’s 2021 update is the inclusion of Honda’s 'Sensing Suite' comprising, forward collision warning, autonomous emergency braking, lane-departure warning, lane-keep assist and adaptive cruise control.

On top of that, the Odyssey also comes standard with blind-spot monitoring, hill-start assist, a reversing camera and rear cross-traffic alert.

The long list of safety is a huge boon for the Odyssey, and with it featuring a third-row of seats, also comes with curtain airbags that extend to seats in the rear.

There are some omissions to the safety list though, with a surround-view monitor not available and the third-row seats missing out on ISOFIX anchoring points.
 

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.

Like all new Hondas sold in 2021, the Odyssey comes with a five-year/unlimited kilometre warranty, with six-years of rust protection assurance.

Scheduled service intervals are every six months or 10,000km, whichever occurs first, but this is much sooner than the industry standard of 12 months/15,000km.

According to Honda’s 'Tailored Service' price guide, the first five years of ownership will cost buyers $3351 in servicing fees, averaging out to around $670 per year.

The Kia Carnival petrol meanwhile, is about $2435 to service over five years, averaging out to be about $487 per year.

The Toyota Prius V also needs to be serviced every six months/10,000km, but the cost of the first five years of ownership totals just $2314.71 – more than $1000 less than the Odyssey.
