Mercedes-Benz C300 vs MG HS +EV

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 MG HS +EV Essence is a nicely specified medium SUV that should suit a lot of people. It looks really nice and I love that it's fairly practical with its features and size but would like some of the tech to improve. It’s not always seamless to use and in this market, tech is very important. The price tag and the on-going costs are hard to beat and if you’re looking for a greener option that will happily cruise in the city or on the open-road, this isn’t a bad option.

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!

It has an inoffensive exterior design that you won’t be embarrassed to be seen in. Curvy in all of the right places, it still manages to look sharp with its tapered LEDs and chrome accents.

It sits firmly within the medium SUV specs at 4574mm long, 1876mm wide and 1685mm high, so navigating your local shopping centre car park will be manageable.

The interior looks polished with the Bader leather sports seats and their suede-like inserts. The air vents are cute and add some personality to the robust dashboard.

There’s a plethora of soft touchpoints throughout that enhance the overall comfort and refinement, too.

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.

The cabin space is very practical with its size. Each row has a decent amount of head and legroom. The big sunroof also makes the cabin feel airy and light-filled, which adds to that roomy feeling.

The leather-accented sports seats are quite comfortable and both are electric but the passenger side misses out on additional lumbar support.

I did have a few comments this week about the front seats, though, mainly that it feels like you’re perched forward in them. It would have been nice to be able to dip the bottom of the seats back.

The individual storage options are solid for this sized SUV with a glove box, two cupholders, drink bottle holders in the doors for front occupants and an air-cooled middle console box.

I missed having a utility tray next to the two USB-A ports and 12-volt outlet, as the Essence features wired Apple CarPlay and Android Auto, but there is a dedicated phone holder next to the cupholders.

Back seat passengers enjoy two cupholders in the fold-down armrest, map pockets and drink bottle holders in the doors.

The seats in the back are well padded but you feel like your knees are propped up a bit because of the shallow footwell. Taller passengers may feel like they’re folding in on themselves.

The technology looks good but isn’t always easy to use. The 10.1-inch touchscreen multimedia system is simple to understand but regularly feels laggy.

It has built-in satellite navigation but a lot of the controls are found via accessing the touchscreen – like the climate control and heating function for the front seats.

The 12.3-inch digital instrument panel is very easy to read but not really customisable.

Charging options are okay and I like the two USB-A ports in both rows but there’s no wireless charging pad or USB-C port which would provide faster charging speed.

The boot is a decent size for the class at 451L and you can bump that up to 1275L if you fold the back seats down. The rear seats have a 60/40 split for added practicality.

There’s a cargo blind and some underfloor storage for the charger and a tyre puncture repair kit. I liked using the powered tailgate but found it a bit glitchy, it sometimes stopping mid-action.

There are only two models in the HS +EV line-up and the Essence is the top dog.

It will cost you $51,990 drive-away and that positions it as one of the most affordable options relative to its rivals. Only the Haval H6 is more affordable at $41,990 (drive-away) but admittedly, it’s by a fair chunk of change - almost $10K!

The Essence is well-specified with Bader leather-accented trims, heated front seats, electric front seats with four-way adjustment for the passenger seats and six-way for the driver, a powered tailgate, as well as a massive panoramic sunroof. The middle console is even cooled with air-control for added convenience.

The exterior hosts full LEDs with its daytime running lights, headlights and tail-lights, as well as, a heated rear window with timed cut off.

It also sports dual-zone climate control up front and directional air vents in both rows, plus multiple charging options add to interior practicality.

Its technology feels up to category standard with the sizing but the usability isn’t as great as its rivals. More on that later. 

And an added bonus. All the paintwork colours are included in 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.

Both HS +EV models share a 1.5-litre, four-cylinder petrol engine and electric motor hybrid combination. Maximum outputs are 189kW of power and 370Nm of torque.

It’s very responsive with its power output and you definitely will be surprised by how much grunt this thing has.

Drive goes to the front wheels via a 10-speed auto transmission but it’s clunky and a bit too slow to shift out of the lower gears. This can make it feel like the engine is pulling back even when you’re accelerating, which I didn’t like.

On the electric motor side of things – the lithium-ion battery has a 16.6kW capacity and 63km (NEDC) driving range.

It has a Type 2 AC charging port but it can’t be hooked onto a fast charger as it lacks the CCS enhanced port. On a 7.0kW system you should see a full charge be completed in around five hours.

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.

With the electric motor being used, the official combined cycle fuel figure is 1.7L/100km and the urban figure comes out at 5.8L/100km.

My real-world usage came to 6.6L. That’s not bad at all, but I have done a lot of open-road driving this week. 

Based on the urban figure and the 55L fuel tank, you should see an approximate driving range of 948km.

MG recommends a minimum 95RON petrol be used. 

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.

I’ve been pleasantly surprised by the overall driving experience. Besides the slower gear shifting, it’s generally smooth to handle. The power is there and makes it easy to keep up with traffic or overtake if you need to.

The suspension handles bumps very well and the steering is responsive. You can tackle corners or a winding road with confidence and without too much roll!

The cabin is quiet, even at higher speeds but you will note the whining of the engine at lower speeds as those gears shift.

On a windy day at higher speeds, the car moves about in the lane more than I like but otherwise, is firmly placed.

The regen braking isn’t customisable but it’s firm enough that you’ll feel it when you pull off the accelerator.

Going down a mountain let me gain five per cent charge on the battery and despite driving over 500km this week I only popped it on charge once (with 15 per cent left) - just to give you an indication of its performance.

I kept the EV mode on default but you can switch it over to a full EV if you want to wring out the most from the electric range.

This is not a difficult car to park and you’ll love its size in a small car park. However, the 360-degree camera view, while pretty clear, is jumpy.

At first, I thought it was laggy but the image just shudders, like a bad connection. I's prefer to see front parking sensors, too, as this MG only has them at the rear.

The safety features are good on the HS and I like the 360-degree camera view but don't like the way the image shudders while in use.

It has a blind-spot monitoring system but the interior ‘alert’ light is in a blink-and-you’ll-miss-it position.

Other features that come standard, are LED daytime running lights, forward collision warning, rear cross-traffic alert, lane keeping aids, lane departure warning, intelligent seat belt reminders, rear parking sensors, traffic sign recognition, a driver fatigue monitor and adaptive cruise control.

It has autonomous emergency braking with car, pedestrian and cyclist detection which is operational from 0-80km/h.

The HS +EV hasn’t been assessed by ANCAP but its fuel-based sibling achieved a maximum five-star rating in 2019.

It only has six airbags, which is pretty low for an SUV, but the curtain airbags cover the back row.

There are ISOFIX child-seat mounts on the outboard seats and three top-tether anchor points but two seats will fit best.

Front passenger space may be compromised a little when a 0-4 rear-facing child seat is installed but overall, it was very easy to install my booster seat this week.

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 ongoing costs are great on this! It comes with a seven-year/unlimited km warranty, which includes the hybrid battery.

It also has a seven-year capped-price servicing plan, which is above average for the class, and services average $426 which is competitive.

Servicing intervals are every 12 months or 10,000km, whichever occurs first, which is fine if you don’t clock a lot of kays every year.
