Mercedes-Benz GLC-Class vs Toyota Kluger

What's the difference?

Like I said right from the start, this new, hybrid version of the AMG GLC63 is technically superior to the model it replaces in every meaningful way. It is faster, more powerful and more fuel efficient and therefore a better performance SUV than the model it replaces.

Is it a better model than the one it replaces? Ultimately that will come down to how much stock you put into the soundtrack and your feelings on an AMG not powered by a V8 engine.

Because if you can see past that, then the AMG GLC63 is an absolutely fantastic performance SUV. Not only does the new powertrain make it faster in a straight line, but the chassis is very well-balanced, making for an engaging driving experience.

For those who can look past the smaller engine they will be rewarded with an incredibly fast and rewarding-to-drive member of the AMG family.

The Toyota Kluger GXL Hybrid has been the ultimate SUV this week, as it fits my gear and family in comfort, the on-road handling is excellent and the fuel usage makes owning this long term actually feasible.

This is a great example of a mid-spec seven-seater that is both functional and comfortable. There’s lots to satisfy here and even though it hasn’t been updated, it may be a case of ‘if it aint broke, don’t fix it’.

The GLC63 is unmistakably an AMG from the moment you first lay eyes on it. That’s thanks to the AMG-specific elements, starting with the grille with vertical strikes and the AMG crest on the bonnet; which is now a signature item for the performance sub-brand.

The GLC63 is also fitted with the Night Package II design kit; this adds a darkened grille and black chrome badging to further enhance its visual appeal.

The AMG-specific alloy wheels and more aggressive stance do mean the GLC63 stands out from the rest of the GLC range, helping it look fast even when it’s standing still.

The Kluger epitomes what a large SUV was originally meant to look like. A big body and with enough ground clearance to earn the tag, but the shape is all long lines and gently curving panelling and that makes it look sleek rather than rugged.

Make no mistake, the Kluger is large at 4966mm long, 1930mm wide and 1755mm tall. It's only only 24mm shorter in its length than its big 4WD Toyota Prado cousin. It's size and road presence assures you that it's capable, but it's not trying to convince you it's a 4WD.

Despite not seeing any design updates, the Kluger still feels relevant and more than holds its own when it comes to kerbside handsomeness.

On the inside, the black synthetic leather trims, softly padded touchpoints and interesting dashboard make the cabin both pleasant to look at and spend time in.

The 12.3-inch multimedia display looks lovely with its clear graphics, but it’s still nice to see some traditional elements - like the gear selector, analogue instrument cluster (with a 7.0-inch digital display) and lots of buttons and dials to play with.

Interestingly, there isn’t a traditional transmission tunnel, which means you get a practical flat floor in the middle row and, thus, more legroom for middle seaters. 

It's a forgiving cabin that lots of different drivers will find something to like in.

Inside the GLC63 is clearly a derivative of the rest of the range, with its C-Class-inspired design and layout, but there’s enough AMG-specific elements to ensure it looks and feels special. This starts with the AMG steering wheel, which comes not only with a thick rim wrapped in Alcantara, but also some AMG special dials to adjust the various performance settings for the powertrain, suspension and transmission.

Then there are the AMG-specific seats, which look good and offer good support for the driver and front seat passenger. The rear seats offer decent space for what is a mid-size SUV, with room enough for two adults or teenagers or three smaller kids.

Those in the back aren’t particularly well looked after though, with only rear air-con vents and small door pockets but no USB charging ports or other small item storage.

The boot is 590 litres, down from 620L in the rest of the range, thanks to the addition of the rear-mounted electric motor. There’s also no room for the temporary spare the rest of the GLC range gets and instead you have to make do with a puncture repair kit.

The Kluger is both practical and comfortable for passengers as each row gets a great amount of head- and legroom – yes, even third-rowers, but the low level of amenities in that row will render it a 'sometimes seat' for adults or older kids.

The 208mm ground clearance, wide door apertures and low-sitting seats makes it a very easy SUV to get in and out of, even for kids. The access to the third row is also good as the 60/40 split middle bench seat can be slid forward.

The electric front seats offer lots of adjustments, including lumbar support on the drivers side, but both seats get heating. They’re also well-padded and quite comfortable on a longer journey.

The outboard seats on the middle row offer the most comfort as they have longer under-thigh support, but the entire row benefits from heavy padding and the seat backs can recline.

The third row offers a curious 60/40 split and is wide enough for two adults to not be squished like sardines.

Although the Kluger is a seven-seater, families will be bummed that there are no child seat anchor points in the third row. But the middle row has two ISOFIX child seat mounts and three top-tether anchor points. It is more than wide enough to accommodate three seats side by side and you’ll have enough room for the front passenger when a rearward facing child seat is installed, too.

Individual storage is above average for the class, but the front row gets the best of it. There are two handy shelves built-into the dash, a glove box, a deep middle console (that swallows my arm) and cubbies in the centre console that include a phone cradle and two cupholders. There's also a sunglasses holder and little cubby beside the driver's knee.

In the middle row, you get two map pockets, two cupholders in a fold down armrest, and a drink holder in each door. While the third row gets a couple of cupholders.

Amenities are well-rounded for the most part, with the three-zone climate control and well-positioned directional air vents in the roof for the back two rows. Middle-rowers also get reading lights and two USB-C ports.

Technology is easy to use and looks great as the 12.3-inch display uses the same multimedia system as Lexus. The built-in satellite navigation is simple to set up and shows clear directions with lots of route customisations available.

There is wired Android Auto and wireless Apple CarPlay, but you do have to initially connect the CarPlay via a cable.

Rounding out the cabin is the great-size boot that offers 241L with all seats in use, but that can jump up to 552L when the third row is stored.

The level loading space makes it easy to slide larger items in and out of, and there’s a handy underfloor storage compartments for smaller items. You get a full-size spare tyre underneath the car and a powered tailgate in this model.

You have to love a simple three-grade line up with variant names that aren't hard to say! The Kluger starts with the base GX, mid-spec GXL and then the flagship Grande model.

All Kluger models share the same all-wheel-drive hybrid powertrain, and our test model is the mid-spec GXL, which is priced from $70,440 before on-road costs.

Its price positions it in the middle of its seven-seat hybrid rivals; the Hyundai Santa Fe Elite ($65,000 MSRP) and the Kia Sorento GT-Line AWD ($73,330 MSRP), but it should be noted that the Sorento hybrid is only offered in one high-spec grade level and the Kluger can’t always match the Sorento’s plush features.

The GXL is still fairly well-specified and includes eight-way powered front seats with heating, adjustable lumbar support (driver's seat), black synthetic leather upholstery, a powered tailgate, rain-sensing wipers, dusk-sensing LED headlights, keyless entry/start and a full-sized spare tyre.

There is also 12 months of complimentary access to Toyota Connected Services, which allows you remote access, via the myToyota Connect app, to safety and security features, multimedia connect and driving insights.

The other technology is well showcased in the 12.3-inch multimedia display that has touchscreen functionality, in-built satellite navigation, wired Android Auto, wireless Apple CarPlay, Bluetooth and digital radio. You also get a single USB-A port, three USB-C ports, two 12-volt sockets and three-zone climate control.

This is what lies at the heart of the AMG GLC63’s success or failure. As I mentioned at the beginning, the previous generation’s 4.0-litre twin-turbo V8 has been replaced by an F1-inspired plug-in hybrid powertrain.

But don’t think that means AMG is suddenly focused on efficiency over performance. When AMG says the powertrain is inspired by the brand’s success in Formula 1 racing, what it means is the battery and electric motor provides a significant performance boost to support the internal combustion engine, not just save fuel.

To that end the combination of the turbocharged 2.0-litre four-cylinder petrol engine and the rear-mounted electric motor produces an impressive 500kW and 1020Nm. That’s a massive jump over the 375kW/700Nm made by the outgoing V8.

All Kluger grades are all-wheel-drives with a smooth continuously variable transmission. They share the same 2.5-litre four-cylinder hybrid powertrain that produces up to 184kW of power. Toyota does not quote a combined torque output.

At first look, these outputs may look underwhelming, but the on-road experience has shown that it’s more than enough to move the Klugers big body around without it feeling underpowered.

The Kluger has a braked towing capacity of up to 2000kg, which means you can hook up most of your weekend adventure toys!

Mercedes makes no secret that the battery is designed for performance, not saving fuel. It only has a 14km EV range but can recharge quickly on the move to provide a power boost when needed.

But despite all that, the GLC63 is actually significantly more fuel efficient than the old V8, using a claimed 7.3L/100km, which is a massive 4.9L/100km improvement over the old model. Although, on our day-long test drive we didn’t manage to come close to that claimed figure and instead saw returns around 11L/100km, albeit after a lot of spirited open-road driving.

The Kluger may be massive but it has an excellent combined fuel cycle usage of just 5.6L/100km because of its hybrid powertrain.

Combined with its large 65L fuel tank, you should see a theoretical driving range of up to 1160km, which is really good for a family SUV and rivals diesel models of the same size.

I’ve been super pleased with the fuel usage of our test model because despite doing quite a few long distance trips, which is where hybrids are usually the most inefficient, I’ve managed a real world usage of only 5.8L/100km! That is a great result.

The Kluger only accepts a minimum 95RON unleaded premium petrol.

Anyone who still believes in the adage ‘there’s no replacement for displacement’ hasn’t driven a modern turbocharged and hybridised engine. The GLC63 is a demonstration of the metaphorical and literal power of modern technology, combining an extremely efficient and potent internal combustion engine with an electric motor to make enormous real-world performance.

To be blunt, the GLC63 feels like a rocketship out of corners, launching with a ferocity and relentlessness the old V8 simply can’t match. It shouldn’t come as a surprise, a mid-size SUV with 1020Nm was always going to have plenty of performance, but even so it’s a shock to the system every time you give the GLC63 full throttle. Officially AMG claims it takes just 3.5 seconds to run 0-100km/h and has an electronically limited top speed of 275km/h - mighty impressive figures for a five-seat mid-size SUV.

To help get all that torque to the road, AMG deploys torque distribution technology that allows for it to be split an even 50/50 front/rear all the way to 100 per cent to the rear tyres.

Other technologies deployed to enhance its handling include AMG Ride Control suspension with adaptive damping and rear-axle steering. There’s also eight AMG Dynamic Select driving modes and four AMG Dynamics settings (Basic, Advanced, Pro and Master), so it’s a complex vehicle that is designed for the enthusiast.

While it’s easy to drive around town, once you get out on the open road you can really get a sense of the GLC63’s performance potential. Beyond just its powertrain the suspension offers good body control and the rear-axle steering helps it feel agile and responsive. 

It’s not perfect though. At times the complexity of the system does lead to some hesitation when you put your foot down. It certainly lacks the linear power delivery of the old V8 and makes for a slightly trickier driving experience at times.

As for the sound, which is one of the biggest elements missing from the V8, Mercedes has added AMG Real Performance Sound, which features a pressure sensor in the exhaust that picks up on the engine note and plays it through the speaker system. It certainly helps make for a louder, more noticeable engine noise, but it still sounds more like an A45 than the previous GLC63 and for many would-be buyers, that’s a major turn-off.

The engine can sound like it’s under pressure, but that doesn’t translate to underwhelming power delivery. The GXL has enough grunt to make it a comfortable open-roader that’s confident on hills and overtaking.

The steering is light for such a big SUV, but with its 11.4m turning circle, it’s every parents dream when doing the school run or navigating small lanes or parks for after-school activities. It’s almost stupidly easy to drive and feels much smaller than what it is, even in the city.

Visibility is mostly good because of the large windows, but the B-pillar is larger than I’d like and I found myself checking my blind spots carefully. 

The ride comfort is really good and suspension is forgiving on the worst of the bumps without feeling like it floats on the road. Road noise is low, even at higher speeds, but occasionally you get a weird wind whistle through the air vents. 

Even those usually put off by a large SUV, should find this comfortable to get around in. Parking it is the only time you really notice its bulk. While the reversing camera is great quality, a 360-degree view system would have been much better.

The Toyota Kluger has a maximum five-star ANCAP safety rating from testing done in 2021 and scored highly across its individual assessment scores. However, it only features seven airbags, which is a bit low for a car of this size, but the curtain airbags extend to the third row, which is good. 

The Kluger has lots of safety equipment, including daytime running lights, hill-start assist, seatbelt warning (all seats), lane departure alert, lane-keeping aid, traffic sign recognition, rear cross-traffic alert, blind-spot monitoring, a reversing camera (with guidelines) and front and rear parking sensors.

The Kluger does miss out on family friendly safety items, like child-presence alert and side exit assist. The adaptive cruise control isn’t as well tuned as I’d like as it doesn't hold it's speed all that well, slows down too soon behind a vehicle, and sometimes can be sluggish to return to a normal speed once a vehicle has left its 'radar'.

The GXL has AEB with car, pedestrian, cyclist and junction turning assist and is operational from 10-80km/h (up to 180km/h for car), but it is usual to see that starting point sit closer to 5.0km/h.

The GLC63 is covered by Mercedes Australia’s usual five-year/unlimited kilometres warranty.

As for maintenance, Mercedes offers service plans, spanning three to five years. Three years will cost you $5025, $6455 for four years and five years is priced from $7180. Servicing intervals are 12 months or 20,000km, whichever comes first.

The Kluger is offered with Toyota’s five-year/unlimited-kilometre warranty, but that can be extended to seven years if you service on time and with a Toyota service centre, which makes it competitive against some rivals.

There’s a five-year capped-price servicing program available, with services costing just $285, which is cheap for the class. Servicing intervals are reasonable at every 12 months or 15,000km, whichever occurs first.
