Volvo XC90 vs Mercedes-Benz GLC-Class

What's the difference?

The XC90 Recharge makes a lot of sense for a family with a couple of kids, who live and spend most of their time in the city and surrounding suburbs.

You’ll need access to a power point for charging and you’ll have to do it regularly to get the best out of this SUV, but in return you’ll get effortless and efficient driving, along with the practicality and prestige which comes with any XC90. 

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.

Cars are like dogs in that a year for them ages them more than one for us. So, this current-generation XC90 which came out in 2015 is getting on in age. Still, the XC90 is a design lesson in how to defy the aging process because the styling even now it appears modern and beautiful. It’s also big, tough, and prestigious looking which is how the flagship SUV in a premium brand should be.

The Thunder Grey paint my test car wore (see the images) is an optional hue, and it suited the battleship size and personality of the XC90. The enormous 22-inch five -spoke Black Diamond Cut alloy wheels were standard and filled up those giant arches nicely.

Maybe it’s the minimalist styling which has kept the XC90 looking cutting edge, because even the interior looks like the inside of a very expensive psychiatrist’s office with those leather seats and the brushed aluminium trim.

The vertical display is still impressive even in 2021, and while fully digital instrument clusters are in everything these days the XC90’s has a prestigious look and matches the rest of the cabin in its colours and fonts.

As for the XC90’s dimensions, it’s 4953mm long, 2008mm wide with the mirrors folded and 1776mm tall to the top of its shark fin antenna.

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.

Clever interior packaging means the XC90 Recharge is more practical than many large SUVs. There are flashes of utilitarian brilliance everywhere from the children’s booster seat which pops out of the centre of the second row (see the images) to the way the XC90 can crouch down like an elephant to make it easier to load stuff into the boot.

The XC90 Recharge is a seven-seater, and like all SUVs with third rows those seats in the very back only offer enough room for kids. The second row is spacious even for me at 191cm tall with plenty of leg- and headroom. Up front as you’d expect has good head-, elbow- and shoulder room.

Cabin storage is good with two cup holders in each row (the third also has containers under the armrests) and there are large door pockets, a decent sized centre console box and a net pocket in the front passenger footwell.

The cargo capacity with all seats being used is 291 litres and with the third row folded flat you’ll have 651 litres of boot space.

Storage for the charging cable could be better. The cable comes in a stylish canvas bag that sits in the boot, but other plug-in hybrids I’ve driven do a better job of providing a storage box for the cable that’s out of the way of your regular cargo.  

The gesture control tailgate works with a foot swish under the rear of the car and the proximity key means you can lock and unlock the vehicle by touching the door handle.

The cargo area is filled with hooks for bags and a lift-up divider to hold items in place.

Four-zone climate control, four USB ports (two in the front and two in the second row) dark tinted rear windows and sun blinds top off what is a very practical, family SUV.

My family is small – there’s just three of us – and so the XC90 was more than what we needed. That said, we found a way to fill it with holiday gear, shopping, even a mini trampoline.

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.

Mercedes-Benz is offering Australia just the GLC300 grade in both the SUV and Coupe body styles.

High-performance AMG variants are out overseas now and will arrive in Australia soon, too.

You can expect to pay more for these AMG beasts - a lot more than the $113,900 list price of the GLC300 Coupe.

Still the GLC300 Coupe does come standard with an AMG Line body kit and 20-inch AMG alloy wheels. LED headlights are also standard, so is the panoramic glass roof, tinted rear glass, proximity unlocking and a power tailgate.

Inside there’s synthetic leather Artico upholstery, sports heated front seats, Nappa leather steering wheel, an 11.9-inch media display with Apple CarPlay and Android Auto, a 12.3-inch digital instrument cluster and a head-up display. There’s also dual-zone climate control and wireless phone charging.

The value is good in terms of features, although the price is slightly higher compared to the rivals such as the BMW X4 xDrive30i ($106,400) and Audi Q5 Sportback 55TFSI ($110,200).

It’s worth pointing out, too, that the GLC300 Coupe is about $10K more than the GLC300 SUV version. Why? The coupe versions of prestige SUVs always tend to be pricier than their regular more boxy SUV siblings. Somebody in marketing will be able to explain why.

Having lived with the GLC300 Coupe with my family over the past few days I can say the proximity unlocking which works by touching even the back door handles is excellent, the tinted windows are dark and cut out much of the sun's glare, but there’s no climate control in the second row. There are air vents back there, which is good.

I found that on hot days the semi-transparent shade on the glass roof couldn’t stop the cabin from heating up quickly.

The XC90 Recharge (Volvo calls it this, so for simplicity let's do it, too) is an all-wheel drive SUV with a 2.0-litre four-cylinder supercharged and turbo-charged engine, producing 246kW and 440Nm, plus an electric motor which adds 65kW and 240Nm.

Shifting gears is an eight-speed automatic and acceleration is rapid at 5.5 seconds for the 0-100km/h sprint.

All XC90s have a 2400kg braked towing capacity.

The 11.6kWh lithium ion battery is located under the floor in a tunnel which runs down the centre of the car covered by the centre console and hump in the footwell of the second row.

If you didn’t realise, this is the type of hybrid you need to plug into a power source to charge the batteries. A power point is fine but a wall unit is faster.  If you don’t plug in, the battery will only get tiny whiff of charge from the regenerative braking and that won’t be enough to put a tiny dent in your fuel consumption.

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.

Volvo says that after a combination of urban and open roads the XC 90 Recharge should use 2.1L/100km. That’s incredible - we’re talking about a five-metre long, 2.2-tonne, seven-seat SUV here.

In my testing the fuel economy varied greatly depending on how and where I drove the XC90.

There was a week where I only drove up to 15km a day doing the day care drop-offs, the shopping, popping into work in the CBD, but all within 10km of my home. With 35km of electric range I found that I only had to charge the XC90 every second day to keep it topped up to full and, according to the trip computer, after 55km of travel I was using 1.9L/100km.

I recharged using the outdoor power point in my driveway and using this method would take just less than five hours to fully charge the battery from empty. A wall unit or fast charger will top the battery up much quicker.

The charging cable is long at more than 3m, and the flap on the XC90 is located on the front left wheel guard.

If you don’t have a way of charging the XC90 regularly then fuel consumption will go up, obviously.

This happened when our family took a break down the coast and the holiday house we stayed at didn’t have a power point within reach. So, while we had been charging the car regularly in the week beforehand with a few long trips thrown in on motorways, for the four days we were away I didn’t plug it in at all.

After 598.4km I filled it back to full at the petrol pump with 46.13 litres of premium unleaded. That comes to 7.7L/100km, which is still great fuel economy given that the last 200km would have been without charging.

The lesson is the XC90 Recharge is most fuel efficient on short suburban and city trips with daily or every second-day charging.  

A larger capacity battery would add more range and make this plug-in hybrid SUV better suited to people who live further out of the city and do more motorway miles.

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.

We put more than 700km on the clock of the XC90 Recharge during the three weeks it stayed with my family, covering a lot of motorway miles, country roads and a stack of urban usage, too.

Now without sounding like one of the haters who hated on me the last time I test-drove a Volvo hybrid, you will need to charge the XC90 Recharge all the time if you want to get not only the best fuel economy, but also the best performance from the SUV, too.

There’s the extra oomph from the motor, when you have enough charge in the ‘tank’ but also the serene and smooth pleasure of driving in electric mode on city and urban trips.

That tranquil electric driving experience feels kind of at odds with a large SUV at first, but having now tested a few big family plug-in hybrids and EVs I can tell you it’s a more enjoyable one.

Movement is not only smooth, but the electric grunt provides a feeling of control with an instant response which I found reassuring in traffic and at intersections.

The transition from electric motor to petrol engine is almost seamless. Volvo and Toyota are only a couple of the few brands which seemed to have achieved this.

The XC90 is large and that presented a challenge when trying to pilot it into my narrow driveaway and in car parks, but light, accurate steering and excellent visibility with large windows and cameras galore helped there.

The auto parking feature works well even on the higgledy-piggledy streets in my neighbourhood.

Topping off an effortless driving experience is air suspension which provides a cushioned and composed ride, with great body control all while wearing those 22-inch wheels and low-profile rubber.

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. 

The GLC was given the maximum five star ANCAP rating in 2022. There’s AEB, active lane keeping assistance and active blind spot warning and nine airbags including a centre airbag.

As mentioned above I especially liked the surround-view camera systems - which let you look right around the car - good for driveway safety and kids.

For child seats you’ll find two ISOFIX mounts and three top tether anchor points in the second row.

I was also impressed to see a space-saver spare wheel under the boot floor and not just a puncture repair kit. 

The XC90 is covered by a five-year, unlimited kilometre warranty. Two service plans are offered: three years for $1500 and five years for $2500.

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.
