Mercedes-Benz GLE-Class vs Volvo XC90

What's the difference?

There’s little wonder the GLE63 S is back for a second go around, after  clearly putting the frighteners on the Audi RS Q8 and BMW’s X5 M Competition and X6 M Competition.

After all, it’s a large SUV that sacrifices little in the way of practicality (especially the wagon) in its pursuit of high performance.

And for that reason, we’re itching to go for another drive – with or without the family.

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

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. 

First things first, the new GLE63 S is available in two body-styles, with the wagon appealing to the traditionalists out there, while the coupe targets the style-conscious.

Either way, few large SUVs are as imposing as the GLE63 S, which is a good thing considering it wants to be taken seriously.

Up front, it’s immediately identifiable as a Mercedes-AMG model thanks to its distinctive Panamericana grille insert.

The angry look is punctuated by the angular daytime running lights integrated into the Multibeam LED headlights, while the chunky front bumper has large air intakes.

Around the side, the GLE63 S stands out with its aggressive wheelarch extensions and side skirts, with the wagon getting 21-inch alloy wheels as standard, while the coupe gets 22-inch items.

From the A-pillars onwards, the differences between the wagon and coupe body-styles start to become apparent, with the latter’s roofline much more steeply raked.

At the rear, the wagon and coupe differentiate themselves even more clearly with their unique tailgates, LED tail-lights and diffusers. That said, they do have a sports exhaust system with squared-off quad tailpipes in common.

It’s worth mentioning that the difference in body-style also means a difference in dimensions, with the coupe 7mm longer (4961mm) than the wagon, despite having a 60mm-shorter wheelbase (2935mm). It’s also 1mm narrower (2014mm) and 66mm shorter (1716mm).

Inside, the GLE63 S separates itself with its flat-bottom steering wheel with Dinamica microfibre accents, and multi-contour front seats, which are upholstered in Nappa leather alongside the armrests, dashboard and door shoulders and inserts.

The door bins are of the hard plastic variety. That’s underwhelming in a vehicle that costs this much, as you would hope cow hide – or at least a soft-touch material – would be applied to them.

The black headliner acts as another reminder of its performance focus, and while it makes for a darker cabin, metallic accents feature throughout, while the trim (our test vehicle had open-pore wood) adds some variety alongside the ambient lighting.

That said, the GLE63 S is still filled to the brim with cutting-edge technology, including two 12.3-inch displays, with one the central touchscreen and the other a digital instrument cluster.

Both use Mercedes’ MBUX multimedia system and feature Apple CarPlay and Android Auto support. This set-up is still the benchmark, thanks to its speed and breadth of functionality and input methods, including always-on voice control and a touchpad.

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.

Being a large SUV, you’d expect the GLE63 S to be quite practical, and it is, but what you wouldn’t expect is the coupe to have 25L more cargo capacity than the wagon, at a generous 655L, due to its higher window line.

That said, when you stow the 40/20/40 split-fold rear bench via the second row’s release latches, the wagon has a significant 220L advantage over the coupe, at a cavernous 2010L, thanks to its boxier design.

Either way, there’s a small load lip to contend with, making loading bulkier items a little more difficult, although that task can be made easier with the flick of a switch, as the air springs are able to lower the load height by a handy 50mm.

Better yet, four tie-down points are on hand to help secure loose items,  alongside a couple of bag hooks, while a space-saver spare resides under the flat floor.

In the second row, things are even better, with the wagon offering a crazy amount of legroom behind our 184cm driving position, as well as two inches of headroom for me.

With its 60mm-shorter wheelbase, the coupe naturally sacrifices some legroom, but it still provides three inches of legroom, while its sloping roofline trims headroom to an inch.

No matter the body-style, the five-seat GLE63 S is wide enough to seat three adults abreast with few complaints, with the transmission tunnel on the smaller side, meaning there’s plenty of room for feet.

There’s also plenty of room for child seats, with two ISOFIX and three top-tether anchorage points on hand for fitting them.

Amenities-wise, rear occupants are treated to map pockets on the front-seat backrests, as well as a fold-down armrest with two cupholders, while the door bins can accommodate a couple of regular bottles each.

A  fold-out cubby is positioned below the air vents at the rear of the centre console, containing two slots for smartphones as well as a pair of USB-C ports.

In the first row, occupants have access to the centre console’s cubby, which features two temperature-controlled cupholders, in front of which are a wireless smartphone charger, two USB-C ports and a 12V power outlet.

The central storage bin is pleasingly large and contains another USB-C port, while the glovebox is also on the larger side, and you get an overhead sunglasses holder too. Stunningly, the front door bins can take three regular bottles apiece. Not bad.

While the wagon has a large, square rear window, the coupe’s is a letterbox in comparison, so rearward visibility isn’t one of its strong suits.

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.

The XC90 Recharge lists for $114,990 making it the most expensive grade in the XC90 range.

Still, the value is excellent considering the number of features which come standard.

The 12.3-inch digital instrument cluster standard, so is the nine-inch vertical centre display for media and climate control, there’s also sat nav, a Bowers and Wilkins 19-speaker stereo, wireless phone-charging, four-zone climate control, power-adjustable front seats, proximity key with auto tailgate and LED headlights.

My test car was fitted with options such as the Nappa Leather perforated and ventilated seats in Charcoal ($2950), the Climate pack which adds heated rear seats and a heated steering wheel ($600), power folding headrests in the rear ($275) and Thunder Grey metallic paint ($1900).

Even at a grand total (before on-road costs) of $120,715 I think this is still good value.

The GLE63 S is powered by Mercedes-AMG’s ubiquitous 4.0-litre twin-turbo V8 petrol engine, with this version pumping out a hard-hitting 450kW of power at 5750rpm and 850Nm of torque from 2250-5000rpm.

But that’s not all, because the GLE63 S also has a 48V mild-hybrid system called EQ Boost.

As its name suggests, it has an integrated starter-generator (ISG) that can provide up to 16kW and 250Nm of electric boost in short bursts, which means it can also reduce the sensation of turbo lag.

Mated to a nine-speed torque-converter automatic transmission with paddle-shifters, and Mercedes-AMG’s fully variable 4Matic+ all-wheel-drive system, the GLE63 S sprints from a standstill to 100km/h in just 3.8 seconds, in either body-style.

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 GLE63 S’s fuel consumption on the combined-cycle test (ADR 81/02) varies, with the wagon achieving 12.4L/100km, while the coupe needs 0.2L more. Carbon dioxide (CO2) emissions are 282g/km and 286g/km respectively.

When you consider the high level of performance on offer, all of these claims are fairly reasonable. And they’re made possible by the engine’s cylinder-deactivation technology and the 48V EQ Boost mild-hybrid system, which has coasting and extended idle-stop functionality.

That said, in our real-world testing with the wagon, we averaged 12.7L/100km over 149km. While that’s a surprisingly good result, its launch drive route mainly consisted of high-speed roads, so expect a much higher number in metropolitan areas.

And in the coupe, we averaged a higher but still respectable 14.4L/100km over 68km, although its launch  route purely involved high-speed country roads, and you know what that means.

For reference, the wagon has an 80L fuel tank, while the coupe has an 85L unit. Either way, the GLE63 S only takes more expensive 98RON premium petrol.

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.

Make no mistake, the GLE63 S is a big beast, but it certainly doesn’t act its size.

Firstly, the GLE63 S’s engine is an absolute monster, helping it to hunker down off the line and then charge on towards the horizon with serious vigour.

While there’s so much initial torque to begin with, you still get the added benefit of the ISG, which helps to eliminate lag as the new twin-scroll turbos spool up.

That said, acceleration isn’t always brutal, as the electronic stability control (ESC) is often quick to cut power when under full throttle in  first gear. Thankfully, engaging the ESC system’s Sport mode solves this issue.

This behaviour is somewhat ironic as the 4Matic+ system is seemingly never short of grip, with it's working hard to find the axle with the most traction, while torque vectoring and a rear limited-slip differential proportion torque from wheel to wheel.

Regardless, the transmission provides predictably smooth and predominantly timely gear changes, although they’re definitely not dual-clutch quick.

What’s more memorable, though, is the sports exhaust system, which keeps your neighbours relatively sane in the Comfort and Sport drive modes, but will drive them mad in Sport+, with hilarious crackles and pops heard loud and clear on the overrun.

It’s worth noting that while the sports exhaust system can be manually engaged in the Comfort and Sport drive modes via a switch on the centre console, it only makes the V8 rumble grow stronger, with the full effect only unlocked in Sport+.

Of course, there’s more to the GLE63 S experience, like the fact that  it somehow rides like a large SUV yet handles like a sports car.

The suspension’s air springs and adaptive dampers offer up a luxurious ride in the Comfort drive mode, with the GLE63 S wafting along with confidence. Not even its large-diameter alloy wheels pose too much of a threat to this quality on poorer country roads.

The ride is still more than liveable in the Sport drive mode, although the adaptive dampers become a  too firm in Sport+, with the ride becoming a little too jittery to be bearable.

Of course, the whole point of the adaptive dampers becoming progressively firmer is to help the GLE63 S handle even better, but the real revelations here are the active anti-roll bars and engine mounts, which effectively limit body roll to such a level that it’s almost imperceptible.

In fact, overall body control is impressive, with the GLE63 S not feeling like the 2.5-tonne-plus behemoth it is. It really has no right to attack corners the way it does, with the coupe feeling a touch tighter than the wagon, thanks to its 60mm-shorter wheelbase.

Further confidence is afforded by the sports brakes, which include 400mm discs with six-piston calipers up front. Yep, they wash away speed with ease, which is exactly what you’d hope for.

Also key to the handling is the electric power steering, which is speed-sensitive and has a variable ratio. It’s really quick in the wagon, and even more so in the coupe, thanks to its more direct tune.

Either way, this set-up is well-weighted in the Comfort drive mode, with plenty of feel and just the right amount of heft. That said, Sport and Sport+ make it gradually heavier, but neither make the driving experience better, so stick with the default setting.

Meanwhile, Noise, Vibration and Harshness (NVH) levels are pretty good, although tyre roar is consistent at highway speeds, while wind whistle is prominent over the side mirrors when travelling above 110km/h.

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.

Volvo has for decades been a pioneer of safety systems to such an extreme that people used to make fun of the brand for being overly cautious. Well, take it from this helicopter parent: there’s no such thing as being overly cautious! Besides, these days all car brands are striving to offer advanced safety systems which the XC90 has had for years. Yep, safety is cool now. Which makes Volvo the Kanye of car brands.

Coming standard on the XC90 Recharge is AEB which works at city speeds to brake for pedestrians, cyclists, vehicles and even large animals.

There’s also lane keeping assistance, blind spot warning, cross traffic alert with braking (front and rear).

Steering support provides assistance during at evasive manoeuvre at speeds between 50 and 100km/h.

Curtain airbags cover all three rows and for child seats there are two ISOFIX mounts and three top tether anchor points in the second row. Note, there are no mounts or points for child seats in the third row.

A space-saver spare is under the boot floor.

The XC90 was given the maximum five-star ANCAP rating when it tested in 2015.  

As with all Mercedes-AMG models, the GLE63 S comes with a five-year/unlimited-kilometre warranty, which currently sets the standard for the premium market. It also comes with five years of roadside assistance.

Better yet, the GLE63 S’s service intervals are relatively long, at every year or 20,000km – whichever comes first.

It’s also available with a five-year/100,000km capped-price-servicing plan, but it costs $4450 in total, or an average of $890 per visit. Yep, the GLE63 S isn’t exactly cheap to maintain, but you expected that.

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.
