Mercedes-Benz GLC-Class vs Mazda CX-60

What's the difference?

The GLC300 Coupe isn't quite as great when it comes to being a family car as the regular SUV version of the GLC, and that's purely down to the sloping roofline which not only makes access more difficult to the second row but reduces boot capacity.

That said, the GLC300 Coupe makes a much better family car than a Mercedes-Benz C-Class sedan, or any sedan.

Easy and enjoyable to drive, packed with great features and still practical, the GLC300 Coupe would still cut it as a good family car.

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.

Coupe SUVs aren’t for everybody… they’re not even for lots of people. But the design of an SUV with its roof cut down so that it meets the tailgate at an almost sportscar-like angle appeals to more than a few fans. The thing is they don’t just like the look, they love it, and they also probably enjoy how much the styling makes other people cranky.

To my eyes the GLC300 Coupe is the best execution of the bodystyle compared to those of BMW and Audi. There’s an elegance to the GLC300 Coupe and the AMG-line adds a tough look that only enhances the solid, powerful but pretty look.

The GLC Coupe is a mid-sized SUV and this new generation model is a bit bigger the previous one and now measures 31mm longer at 4763mm end to end, it’s 1890mm wide, 1605mm tall and has a wheelbase of 2888mm.

It’s also more aerodynamic than ever. No seriously, it’s drag coefficient is now 0.27 and it looks like a bar of soap - and it's about as slippery as one, too.

More curved surfaces await inside with a dashboard that pours down into the large centre console and it's adorned with a sloping and large portrait-style media screen. 

At night or in tunnels the ambient lighting glows through the air vents and skirts the edges of the door trims, console and dashboard.

It’s a minimalist and high-tech cockpit with modern sports seats up front and a Nappa leather wrapped steering wheel with its twin blade design.  

So, how does the coupe design work for family practicality? Let’s take a look.

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.

SUVs are the most practical cars for families because of the better access to the cabin thanks to their large doors and slightly elevated ride height, their big boots with wide and tall hatch openings and their high flat rooflines. They’re essentially raised station wagons.

A coupe-style SUV still has four doors but they are less boxy due to the sloping roofline which falls away quickly to meet the tailgate at a lower point. The effect is a sporty-looking shape but practicality is lost in this exercise of form over function.

The second row doorways aren’t as large as those on the regular SUV. I did a side-by-side test and felt like I had to duck under the sloping roof when getting out of the back seat.

The smaller opening also made it trickier to lift my toddler daughter into her baby seat.

The sidesteps are also surprisingly handy for bigger kids and my eight-year-old used them every time when climbing into the car.

Cabin storage is outstanding with huge door pockets and cupholders in both rows, and while the 545-litre boot in the GLC300 Coupe is 80 litres smaller than the cargo capacity of the regular GLC SUV, it's bigger than the previous version of the Coupe.

As for people space, there’s enough headroom for me at 189cm tall in the back seat and heaps of legroom, even behind my driving position.

I’ve mentioned the lack of climate control in the second row, but also should point out that there are no USB ports back there either.

There are USB ports in the big centre console box upfront and a long cord should be able to make it to the second row. 

There’s a wireless phone charger but it's housed in the bowels of the centre console too, and you’ll need to weave your hand while clasping the phone under the shiny black trapdoor, past the cupholders possibly with drinks in them and almost under the dashboard.

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.

There are three models for the CX-60 and ours is the mid-spec model, which will cost you $80,300, before on-road costs.

You get a decent number of features in this grade, so it feels well-positioned against its rivals.

The Lexus NX350h F Sport Hybrid AWD beats it by a smidge at $80,500 (MSRP) and the Volvo XC60 Recharge Plus sits well above at $92,990 (MSRP).

As you’d expect there are some luxury items to be found, like the panoramic sunroof, heated front seats, heated leather steering wheel, and heated rear outboard seats.

You also enjoy the following as standard - dual-zone climate control, electric front seats, leather-accented trim, electric steering wheel adjustment, satellite navigation, keyless entry, a hands-free powered tailgate and a 360-degree view camera system plus a bunch of upmarket technology which we’ll touch on later. 

The GLC300 Coupe has a 2.0-litre four-cylinder turbo-petrol engine making 190kW of power and 400Nm of torque.

There’s also an overboost function which allows the engine to make an extra 17kW and 200Nm just for a brief moment, but that extra dollop of grunt combined with the regular output provides impressive acceleration (0-100km/h in about 6.3 seconds) for overtaking or moving quickly when you need to.

A smooth nine-speed automatic transmission sends the drive to all-four wheels.

The GLC300 Coupe is all-wheel drive and while there’s a setting for rougher terrain, along with one for comfort, eco and sport, but I’d make sure that it doesn’t get any more adventurous than tame gravel and dirt roads.

Mercedes-Benz refers to the GLC300 Coupe as a mild hybrid and this is because it has a 48-volt system and an integrated starter-generator.

This type of hybrid doesn’t use electric motors, doesn’t drive the wheels and won’t save much fuel, but it will provide efficiencies by supporting the engine and when coasting, plus will reduce petrol consumption to a small degree.

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.

As we mentioned above the GLC300 Coupe's 48-volt mild hybrid system is not the kind of hybrid that will allow you to drive miles on electric power, nor will it dramatically reduce fuel consumption in the way a parallel, series or plug-in hybrid will. But every bit of efficiency helps.

Mercedes-Benz says the GLC300 Coupe will use 7.7L/100km after a combination of open and urban roads. 

We had the GLC300 Coupe for just two days, but in that time my family covered 176km of regular daily usage which took in motorways but mainly suburban duties such as the school run, supermarket dashes, that sort of thing.

In our fuel test we measured 14.48 litres at the fuel pump which works out to be an on-test fuel use figure of 8.2L/100km and not far off the manufacturer’s claim. 

While this fuel consumption isn’t overly high, a plug-in hybrid or even a parallel or series hybrid could return about 5.0L/100km or less.

Mercedes-Benz has dropped plug-in hybrids from its Australian range which is a shame because it would be good to see more efficient options in the GLC range. Of course if you want more efficiency from a Benz of the same size, there is always the fully electric EQB or EQC.

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.

There’s a lot to like here but the short version is the GLC300 Coupe has a comfortable ride, but good handling, with a responsive engine, although rear visibility through the small back window is poor.

If we drill down a bit further I can tell you that excellent cameras around the car will help you check to make sure kids aren’t running around behind you and that forward and side visibility through the window is good.

An important takeaway is that the GLC300 Coupe is easy to drive with light steering and an engine that’s mild and controlled in its power delivery.

The gear shifter is mounted on the steering column, in the same way an indicator lever is. So putting the car into Drive, Reverse and Park is so easy and means you don’t have to take your hands off the steering wheel. 

As a family car I liked the good body control and composed ride. We have a small toddler that we can sometimes only get to sleep by taking her for a drive and we found that she could nod off and not be woken by potholes and speed bumps or too much leaning in the corners. 

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.

The CX-60 has a lot of safety features I like to see on a family car and a highlight is the intelligent blind-spot monitoring system which shows the vehicles around you in a dynamic display on the instrument panel.

Other standard safety features include LED daytime running lights, lane departure alert, lane keeping aids, rear cross-traffic alert, forward collision warning, intelligent seat belt reminders, a driver fatigue monitor, front and rear parking sensors and a 360-degree view camera system.

It also has adaptive cruise control but it was a bit hit or miss. It’s quite sensitive and sometimes registers a larger vehicle, like a truck, as still being in your lane despite overtaking.

It has autonomous emergency braking with car, pedestrian, cyclist and junction assist detection that’s operational from 10–80km/h (although the car detection is operational from 4.0–160km/h).

I’m happy to say this system works well – a ‘roo jumped out in front of me this week and the car performed an emergency stop with plenty of room to spare.

It achieved a maximum five-star ANCAP safety rating from testing done in 2022 and it has eight airbags, including a driver’s knee- and a front centre airbag.

There are ISOFIX child seat mounts on the outboard seats and three top tethers and while two seats will fit best, you might get lucky with three skinny booster seats. There’s also plenty of room when a 0-4 rearward facing child seat is installed.

The GLC300 is covered by Mercedes-Benz's five-year, unlimited-kilometre warranty. 

Services are annually or every 25,000km. And you can buy a three-year service plan for about $3000.

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.
