Mazda CX-60 vs Mercedes-Benz E300

What's the difference?

The Mazda CX-60 GT P50e will suit those families that don’t need the extra seats of its bigger siblings but still want some luxury and comfort. I like the features and the hybrid efficiency but don't like how it handles in the city. I got used to it but it’s not my favourite plug-in hybrid to drive and for the higher price tag, I did expect a smoother experience.

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.

Note: CarsGuide attended this event as a guest of the manufacturer, with accommodation and meals provided.

For me, Mazda SUVs are a bit too similar to get me excited. It’s a case of ‘same same but different’ when they’re on the road.

Each one looks like a scaled version of the other but the GT’s body colour extends to the lower cladding and wheel arches, which makes it appear larger than the CX-5 at least.

The GT model is also set apart from the base Evolve model with the heavier use of black accents – like the gloss black side mirrors, 20-inch alloy wheels and honeycomb grille. It’s 'PHEV' and 'In-line 6' side badges are also blacked out for added sportiness.

Full LED exterior lights in Mazda’s classic slim-line look plus some added ‘in-take’ vents at the front complete the overall package.

In the cabin, there’s a strangely wide panel on the dashboard that separates the centre console from the media system and it doesn’t look right compared to the skinny air-vents and button panel that sits below it.

The interior does sport black leather-accented trims and enough soft touchpoints that there is a sense of quality throughout but I was hoping for a more luxuriously-appointed interior, given the price tag. Especially considering the top-spec CX-5 model is a good $25K more affordable.

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.

The cabin is practical with its great sense of space in both rows, which is not always the case for a mid-sized SUV. Taller families will love how much legroom there is to be had.

The front passenger can get comfortable with the eight-way power adjustments on their seat but the driver enjoys the most perks with 10-way adjustments, lumbar support and two-position memory function.

Both seats have heat function (up to three levels) and are well-cushioned for a longer trip.

The rear seats are well-padded and feature a handy 40/20/40 split-fold for internal storage. The outboard seats also have a heat function for added comfort.

My six-year old found this car to be super easy to get in and out of because of the 175mm ground clearance. He also enjoyed a good view from the wide windows and liked the amenities, like the directional air vents and reading lights.

Individual storage is decent in both rows but the front passengers get the best options with two cupholders, extra-large storage bins in each door, a glove box and a middle console, which is on the shallow side.

Back seaters get two cupholders in the fold-down armrest, small storage bins in each door and a couple of map pockets.

The technology looks upmarket with the dashboard being headlined by two separate 12.3-inch digital screens.

The multimedia system is easy enough to use but I wish Mazda enabled touchscreen access on this as it’s a pain to use the rotary selector dial while on the go.

That said, it’s fab that you get wireless Apple CarPlay and wired Android Auto, plus built-in satellite navigation.

The premium Bose sound system with its 12 speakers makes for a concert-like experience and the charging options are good throughout the car.

Up front you get two of the faster USB-C ports, a 12-volt socket and a wireless charging pad to choose from.

In the back seat you get another two USB-C ports plus a handy 220-volt (150W) port for bigger items. In the boot you get another 220-volt port but this one has 1500W capacity, so larger appliances can be hooked up.

The boot rounds out the cabin practicality with a decent 477L of capacity but you can bump it to 1726L if you fold down the rear seats. There are manual levers in the boot to do this.

The level load space makes it easy to slide things in and out and I always enjoy having a powered tailgate. A flipside to all of this room though is that you only get a tyre puncture repair kit rather than a physical spare.

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.

While cross-shopping the E-Class and a BMW 5 Series would normally be relatively easy, the Merc’s $131,500 starting price, before on-road costs, puts it plenty north of the base 520i, the only petrol one available, at $114,900. The electric i5 eDrive40 starts from $155,900, more than $20K over the Mercedes.

But the E-Class is stacked with features as standard, and while there are a couple of option packs, Mercedes Australia has tried to streamline the most popular features and specifications into the E300.

Its $131,500 price gets you a tech-heavy sedan with Merc’s latest 'MBUX' system housed in a visually impressive, if perhaps unnecessary, 'Superscreen' dash.

The dual-screen set-up incorporates a main 14.4-inch central multimedia touchscreen and a 12.3-inch display for the passenger, allowing the driver to keep, for example, a map visible while a passenger sorts out media or comfort settings.

The system is also designed to avoid taking users through sub-menus, though can be bypassed by wireless Android Auto or Apple CarPlay.

It also features a selfie camera mounted to the dash, which is disabled for the Australian market at present. Mercedes-Benz Australia hopes to change this soon.

Mercedes also plans to allow the MBUX system to learn what settings and functions will be most useful to the driver under certain conditions, but currently users are able to manually create so-called ‘Routines’ such as setting the climate control and seats to warm up if it’s below a certain temperature, and can even adjust the ambient lighting to a warmer colour.

More automation comes in the brand’s MBUX ‘Hey Mercedes’ system, which can now respond to commands without the driver needing to say “Hey Mercedes”. 

Heated and vented front seats, leather upholstery, wireless phone charging, and a 17-speaker Burmester sound system with Dolby Atmos 4D sound are also standard - the latter being a clever feature that positions different elements of the audio, usually music, to give a 360-degree feeling, as well as turning bassier tones into a physical vibration via “tactile transducers” in each front seat’s backrest. Good for bassline junkies, then (apologies to Mr. Rascal).

With the $9400 'Plus Package', the E-Class also comes with 'Airmatic' suspension and rear-axle steering (which I’ll touch more on later), power-closing doors, 'Urban Guard' to monitor your vehicle while it’s parked, an illuminated grille up front, a more capable version of the MBUX 'Interior Assistant', four-zone climate control and Mercedes’ 'Digital Light' function, which uses the more-than one-million pixels in the headlights to project onto the road or surface in front of you when turning the car off or in driving situations to alert road users of potential danger.

A $6200 'Energising Package' adds multicontour front seats with comfort headrests, upgraded climate controls with 'Air-Balance' and fragrances, upgraded seat heating with armrest heating for the front occupants and heated seats for the rear.

The GT P50e has a 2.5-litre, four-cylinder petrol plug-in hybrid powertrain with a maximum power output of 241kW and 500Nm of torque.

This is an all-wheel drive and has an eight-speed auto transmission.

Overall, it’s fairly gutsy and you’ll be pleased with that power when you hit the open road.

On the electric motor side of things, this also has a lithium-ion battery with a relatively small 17.8kWh capacity which gives you a driving range of up to 76km when in pure EV mode. 

It has a Type 2 AC charging port but it can’t be hooked onto a fast charger as it lacks the CCS DC connector.

On a 7.0kW system you should be able to get from 20 to 80 per cent in as little as 90 minutes. The household plug charging time is more like seven or eight hours, so best to leave overnight when at home.

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 official combined cycle fuel figure is 2.1L/100km but after an almost 600km roadie and charging it twice, my real-world usage came to 6.4L.

That's a good result considering this car's power and size but you will get the best efficiency if you charge the battery regularly. 

Based on my usage and the 50L tank, I’d be able to get a rough driving range of 781km.

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.

Well .. let’s unpack that shall we? Yes, this thing certainly has power but the biggest surprise for me was how the electric motor and combustion engine talk to one another because it doesn’t make for the smoothest driving experience in the city.

Therein lies the rub, for me. At this price point I was hoping for a smoother drive experience. In fact, it performs in the strangest of ways - when you’re accelerating, it feels like you’re in a much lower gear than you ought to be.

Almost like you’re stuck in 4WD. There is a sensation of the engine being held back and fighting you when you drive this in built up areas.

The ride comfort in the city was affected by this because it has a tendency to bunny hop/lurch when you hit corners at lower speeds. However, it has beautiful manners on the open road and that is where this model shines for comfort and handling. 

In this environment the steering feels concise and you can handle winding roads at speed without much roll. It can get a little noisy in the cabin as the electric motor wheezes a lot but otherwise, it’s alright for highway driving.

Overall, it's pretty good to park and I like the tight 10.8m turning circle. The 360-degree camera system is clear, too, but coupled with the front and rear parking sensors, you won’t have any issues.

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.

ANCAP hasn’t had a go at crash-testing the E-Class yet, and it might not given the relatively small number that will be sold here compared to volume models, but Mercedes’ track record with safety is pretty stellar, and it’s extremely rare for a Mercedes to not cop the maximum five stars.

In the new E300 there are 11 airbags - plenty for a sedan. Mercedes lists front airbags, knee bags and pelvic/thorax airbags for the driver and front passenger, side bags for the rear and a front centre airbag.

It also comes with a fairly extensive suite of safety tech, including the usual ABS, lane-keep assist, blind spot monitoring and surround-view parking cameras.

But on top of that, there’s also ‘Evasive Steering Assist’, semi-automated cruise control with sign recognition, distance assist for following leading vehicles and can even project light arrows onto the road if leaving your lane, when 'Digital Lights' are optioned.

The E-Class also has a function if an imminent collision is detected in which it can, depending on the type of collision, take occupant protection measures. In the case of a side-on collision, the E-Class can “move an affected front occupant towards the centre of the car” before impact.

The ongoing costs are pretty reasonable. It comes with a five-year/unlimited km warranty which is usual for the class. It also has capped-price servicing for five-years or up to 75,000km, whichever occurs first.

Services cost an average of $518, which is a little expensive for this class but servicing intervals are fine at every 12 months or 15,000km, whichever occurs first.

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.
