Mercedes-Benz E300 vs Mazda CX-80

What's the difference?

The E-Class is stacked with kit, looks great, and is an effective and comfortable way to get around in built-up areas or across the countryside.

While it’s not the most dynamically engaging - it’s pipped by its Bavarian rival there - it offers more comfort-oriented features than most, and the cabin is a pleasant place to spend a day driving.

If you're disposed towards stumping up the asking price, the extra outlay for the 'Plus Package' will probably be most relevant to you if you’re covering long distances due to the Airmatic suspension.

Otherwise, even a simple-spec E300 provides a step up from what you might expect from an executive sedan.

The Mazda CX-80 Touring G40e will do everything you ask of it and outside of pricey ongoing costs, there’s not much to annoy. It’s too large for my small family of three and if it’s kid stowage that you’re looking for, a people mover might offer better practicality and comfort than what this does. Would it be a model that you jump through hoops to get? Maybe not, but it still has a place as family hauler and is easy to drive.

Evolution rather than revolution is obvious when it comes to the E-Class’ styling, but that’s in Mercedes’ best interests, because it’s still a good-looking thing, and being a bit subtle is warranted in the executive sedan game.

The biggest changes come in the headlights and tail-lights. Up-front there are now more than one million pixels in the LED headlights, which have adaptive high beam as standard and are more connected to the grille via black trim, as has been seen in EQ electric models.

Underneath, the bumper now features an AMG-style 'A-wing' apron as part of the 'AMG Line' exterior package as standard. A set of 20-inch AMG alloys are also included.

To the rear, and the digital tail-lights feature a Mercedes-Benz star motif, making its lighting signature now more recognisable from behind.

The German Rainbow is well-represented with mostly shades of grey, black, or white available, though 'Verde Silver Metallic' is a slightly retro green, and 'Nautic Blue Metallic' is a subtle and classy tone.

The daring ‘Manufaktur’ shade of 'Patagonia Red Metallic' is a $2500 option, as is 'Opalite White Bright' while 'Alpine Grey Solid' is $2900.

I've said it before but Mazda SUVs all look like scaled versions of each other to me and the CX-80 looks ridiculously similar to every other larger SUV model in the Mazda stable with the long pronounced nose that features sharp LED lighting and its general robust size.

The rear is where it differs with the proportions becoming a little bulbous but it’s practically shaped and overall is a nice-looking family SUV at the kerb side.

Head inside and the interior is pleasant with its high-quality trims and heavy-handed styling that matches the exterior dimensions with big panelling and air-vents up front to balance out the long width of this dashboard.

However, the whole car tends to lack personality for a model that’s a part of Mazda’s ‘premium SUV’ range. It's nice but doesn't add anything new.

Inside, the E-Class should feel familiar to anyone who’s spent time in a recent Benz, though the Superscreen might be the main point of difference. It’s an immediately comfortable place, though, with a relatively visually busy cabin.

The seats and their adjustability mean most drivers and passengers, regardless of height and size, should feel supported (and ideally relaxed), while touch-points are mostly either leather upholstery or digital screens.

The steering wheel, also seen in plenty of other Mercedes models, is a bit of a let-down, however, with its haptic touch pads on a slightly busy two-tier layout. This millennial found it irritating, surely too will the usually older E-Class buyer.

There are a few other small annoyances, one being that the MBUX Assistant sometimes won’t hear a command, or that not everything seems to be able to be controlled by it. The climate control vent positions are electrically adjustable to certain pre-sets through the menu, but the MBUX Assistant isn’t able to do this for you.

And while the driver display and central multimedia screen are fairly user-friendly, it’s not always immediately apparent what the quickest way to find some information or a setting is.

Our test car was fitted with the 'Plus Package', which means four-zone climate control available to the rear seats, which my 180cm-tall self found spacious with plenty of headroom, kneeroom, and even a fair bit of room under the driver’s seat.

Behind the rear seats, there’s a generous 540 litres of boot space, exactly the same capacity as the previous generation E-Class.

Seven-seat SUVs tend to really be a 5+2 combo, where the rear two seats are for kid- or emergency-use only. You'll be pleased to find that all passengers enjoy a decent amount of space in each row in the CX-80. The third row is still a little cosy for an adult but my 6ft2 brother managed to get back there without too many grumbles. However, we all giggled as he sort of fell in due to the lack of handholds (sorry, Mack).

Otherwise, the 170mm ground clearance and wide door apertures make it an easy SUV to get in and out of. The doors are heavy and sometimes miss their 'hold' position if you open them too quickly, making them swing back. My eight-year-old got whacked a few times because of it!

Amenities and storage are best in the first and second rows with front occupants enjoying those heated seats, two USB-C ports, a 12-volt socket and wireless charging pad. You also get dual-zone climate control, and powered seats with adjustable lumbar support. The seats are well-padded but fairly narrow and short in the base, making it easy to fatigue on longer journeys.

Storage includes a large glovebox that can hold a manual and a fair bit more, a shallow but handy middle console because of its dual-opening lid and a total of four drink holders. There's a sunglasses holder but not much else for smaller loose items.

In the second row you get two map pockets, a small storage bin in each door and a total of six drink holders. There's also individual reading lights, two USB-C ports, climate control, directional air vents, a fold-down armrest and retractable sunblinds (always a winning feature in my house).

The third row gets four drink holders, two USB-C ports and two directional air vents.

Feedback from my passengers (kids and adults alike) hasn't been great for the air-conditioning system with all complaining how long it took for the rear two rows to cool down. The low and awkward positioning of the air vents also prevents direct air flow to passengers. The third row is impacted by this as the passenger's legs cover them.

The rest of the technology is solid with the multimedia system offering a rotary dial operation. The system hasn't seen any recent updates, so if you're familiar with the Mazda system, you'll get along just fine.

The built-in satellite navigation is simple enough to use and the wireless Apple CarPlay is easy to connect to. There's also wireless Android Auto. Call connections remained consistent but feedback was that there seemed to be a fair bit of background noise on my end during calls.

Rounding out the interior is the boot space which offers a level loading space, retractable cargo blind and underfloor storage which houses the tyre repair kit. There's also a 12-volt socket and 220-volt/150W AC socket housed on a side panel.

With all three rows up, you get 258L of capacity and that figure jumps up to 566L when the third row is stowed. The CX-8 offered more boot space but the CX-80 is still respectable for the annual family road trip. Plus you get a powered tailgate function in the Touring model, which is always appreciated.

Mazda offers a choice of five CX-80 grades and for almost all of them, you get the option of a new mild hybrid petrol or diesel, or a plug-in hybrid powertrain.

The Touring G40e model on test for this review is second-from-the-bottom and has a petrol mild-hybrid powertrain. It is priced from $61,950 before on-road costs and the Artisan Red Metallic paintwork our test model has adds $995 to the price tag.

The Touring is more affordable than some of its rivals, including the Toyota Kluger GXL at $70,440 MSRP and Hyundai Santa Fe Elite at $62,500 MSRP. However, these two models are full hybrids and the Santa Fe has a slightly longer features list for only a little bit more money which makes it better value overall.

The great thing about Mazda is once you move up from the entry grade, you often benefit from a host of great standard features that would usually come as part of a package or cost extra with other brands. For example the Touring gets leather upholstery, heated and powered front seats and a wireless charging pad, which isn't too bad for a grade that sits towards the start of the range.

There are some solid practical features like the keyless entry and start, rain-sensing wipers, dusk-sensing headlights, powered tailgate, three-zone climate control, retractable sunblinds (second row) and 360-degree view camera system.

Tech feels well-rounded with a 10.25-inch multimedia system, six USB-C ports, two 12-volt sockets, a 220-volt/150W AC socket, satellite navigation and wireless/wired Apple CarPlay and Android Auto.

In terms of value within the CX-80 range, the Touring G40e is the pick of the litter.

This lone E-Class variant is powered by a turbocharged 2.0-litre engine pumping out 190kW and 400Nm, assisted by a 48-volt battery system. Under EQ boost, an extra 17kW and 205Nm is available for a short time.

It’s hooked up to a nine-speed auto that drives the rear wheels, and it’s all pretty traditional… for 2024, that is.

Mercedes says the E300 is able to hit 100km/h in a respectable 6.3 seconds.

 The CX-80 Touring G40e model has an eight-speed auto transmission and all-wheel drive via a 3.3L turbo-petrol in-line six-cylinder engine coupled with a 48-volt mild hybrid system that produces up to 209kW of power and 450Nm of torque.

It’s not ridiculously powerful but pick up is great and there's more than enough to move the CX-80's big body around and support a 2500kg braked towing capacity.

Mercedes claims the E-Class drinks 7.2L/100km on the combined cycle, and though we weren’t able to test that properly at the pump on the launch program, the trip computer showed up to 9.4L/100km after some quite spirited driving, which gradually averaged out to about 8.6L/100km in the afternoon once some more calm, E-Class-appropriate distance had been covered.

With its 50L fuel tank, the E-Class should theoretically be able to cover 694km on a single tank if the 7.2L/100km is achieved, though realistically it would be much less, 550-600km depending on driving style.

The Touring G40e model has a 74-litre fuel tank and an official combined fuel cycle usage of 8.4L/100km, which gives you a theoretical driving range of up to 880km.

The mild-hybrid system works well enough that I didn’t hit double digits for fuel usage despite not being shy on using the power while hauling cargo and people on a mix of open road and urban trips.

My real-world use popped out at 9.3L/100km and while the diesel variant has much more efficient outputs and range, this result is pretty good for such a massive SUV.

While the E-Class has taken fairly sizeable steps in terms of its tech, it remains a fairly traditional car from behind the wheel, save for a few small changes like its mild-hybrid system and rear-wheel steering.

It’s still a petrol-powered rear-drive sedan, and it feels built more for eating up highway kilometres than it does tackling twisty turns. But that’s okay, because it will still do the latter.

Comfort is the main focus, clearly, for the E300, and the big Merc does it well. We weren’t offered a car without Airmatic air suspension on the launch, but the E-Class doesn’t seem like it would be particularly rough without it.

With it, however, large bumps and minor road annoyances only make their way into the cabin in the sense that you’re aware of them, but not bothered by them.

That slight dulling of feedback does extend to the steering wheel however, where, despite the rear-wheel steering making the car more nimble, the feedback to the driver is less encouraging of eager driving. 

While 190kW on paper doesn’t seem like enough, the E-Class makes do with its meagre engine quite well - and even though it can seem like it’s working a bit too hard at times, the E-Class’ natural state isn’t responding to a planted foot, so it’s unlikely to be a daily bother.

Engine noise, as well as wind and road noise are suitably dulled by the E300’s NVH fitout, too.

The tuning of its drive modes, in particular Comfort and Sport, seemed well-judged on our drive loop, with the option to set the 'Individual' mode to a custom configuration, most elements in Comfort while the drivetrain is set to Sport is particularly helpful when on gentle, high-speed country roads.

If you do start to approach the limits of the big sedan’s capability, it’ll let you know fairly early on. The heavy E-Class isn’t prone to sudden lurching or poor handling, and isn’t much phased by mid-corner bumps.

It’s not as dynamically engaging as some rivals, particularly the 5 Series, but it does appear to be a better provider of cross-country comfort.

The Touring G40e model is pleasant, if a little boring, to bum around in. Boring may be too strong a word but there's not much that gets you excited about the driving experience. The Touring performs and has decent power through most situations but it lacks a certain edge. It's not particularly sporty, nor does it sound mean when you put your foot down.

It's nice and does what you expect it to do.

The ride comfort is good with cushioned suspension with enough road feedback but people in the back will jostle a bit over the worst of the bumps.

Road noise can creep in at higher speeds and third rowers will struggle to be a part of the conversation but overall the cabin is refined for longer journeys.  

Visibility is mostly good because of the big windows but the wider pillars mean I check my blind spots very carefully, as the side mirrors seem a tad too small for the bulk of the car.

The CX-80 has a small turning circle of 11.6m and most of the time it never feels like it lumbers, but when you’re manoeuvring it in a tight car park the steering can feel heavy and a three-point turn starts to feel clumsy.

A saving grace is the excellent quality of the 360-degree camera system which takes out some of the puff from parking it. The CX-80 fills a space and it’s one you'd be careful to park so you don't get crowded.

At the time of this review the new Mazda CX-80 hasn’t been tested with ANCAP and is thus unrated but it has 10 airbags which is great for a big family SUV and includes side-chest airbags for the second row and curtain airbags that extend to the third row.

The Touring G40e model features a robust list of standard safety features including auto emergency braking (AEB), safe exit assist, front and rear cross-traffic alerts, blind-spot monitoring, driver attention alert and monitoring, forward collision warning, lane keeping aid/departure, front and rear parking sensors, a 360-degree camera system, traffic sign recognition, intelligent seatbelt warning and a tyre pressure monitoring system.

The adaptive cruise control is one of the most user-friendly I’ve sampled recently and other than a sensitive lane keeping aid, all systems follow that user-friendly vibe.

There are a total of five top-tether points and two ISOFIX child seat mounts. The width of the middle seat means you should be good to fit three child seats side by side if they're not too large.

The E-Class comes with Mercedes’ fairly industry standard five-year, unlimited kilometre warranty, though Mercedes-Benz Australia was unable to confirm exact servicing pricing on the launch. 

It does however list pricing for the E-Class on its website for a three-service pack at $3325, four at $4535, and five at $6800, the latter averaging out to $1360 each.

This could increase with the new generation car, and Mercedes doesn’t list estimated serving pricing for new E-Classes yet in its booking system (I checked with one of the test cars).

Servicing intervals are every 12 months or 25,000km, whichever comes first.

The CX-80 is let down a bit by its ongoing costs.

Mazda offers the CX-80 with a five-year/unlimited kilometre warranty which is fairly standard. A number of its rivals are offered with up to seven-year terms these days.

You get a five-year servicing program with services averaging $694, which makes it on the more expensive side, but servicing intervals are reasonable at every 12 months or 15,000km, whichever occurs first.
