Range Rover vs Mercedes-Benz GLC-Class

What's the difference?

The Range Rover Autobiography long wheelbase is an outstanding SUV that is not just beautiful to drive but makes family practicality a priority, too, 

The price is reasonable relative to the competition, the features list is long and complementary servicing offers peace of mind.

If you don’t need the third row, I’d consider the standard wheelbase Autobiography even if it does reduce legroom, there’s still plenty of space.

My son stopped short of giving the Range Rover Autobiography full marks "because there are no massaging seats in the second row".     

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.

This fifth-generation Range Rover debuted in 2021 and despite its smooth, modern styling this SUV retains the familiar traditional Range Rover look with the short squared bonnet, flat roofline and tall windows.  

Let’s talk about the wheelbase, because it has a huge impact on passenger space.

We had the long wheelbase which is 3197mm between the front and rear wheels - that’s 200mm more than the standard wheelbase. 

Just look at those stretched rear doors in the photos - this is a go-anywhere limousine, or go-anywhere daycare centre in my case.

The overall length of the long wheelbase Range Rover is 5252mm. That’s big, but the design of this SUV doesn’t make it appear enormous.

What I don't like are the retractable door handles. They take a while to pop out and they look and feel cheap. Land Rover has used these on its other SUVs and if I had time I’d pen a letter asking the company to please stop. I’m sincerely hoping this review will do the same thing. I await your response JLR.

I think the tail-lights are pure genius. The pencil thin design is such a brave move away from the norm where brands are going over the top with LED lighting, and the simplicity is refreshing.

Inside, a traditional-looking Range Rover cabin awaits you with the flat dashboard, the low window sills contrasted by super modern touches like the displays and fully digital dials.

It’s sumptuous, luxurious, but not over the top. Again some people are looking for bling and gimmicks, but you won’t find them here - and I like that. This interior feels solid and substantial, but plush. 

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.

Range Rovers have been a family favourite for decades and they’ve been doing school runs and trips away long before other brands even thought about producing SUVs for families.

So what you’re buying is Land Rover’s decades of knowing how to make a family SUV and you can tell by little things such as, how wide the doors open, how easy it is to get in and out of (even for little kids), the flat floor, the good visibility (thanks to low window sills), and then there’s the space and cabin storage. Stuff other brands seem to be still working out.

The second row seats in the Autobiography have electric sun shades, dual-zone climate control and the window seats are power adjustable and heated.

My eight-year old couldn’t resist playing with his electric sunshade and the seat adjustment, but fortunately the driver has an override switch which let me turn off his 'seat privileges’ as he called it. 

Being the long wheelbase means the rear doors are long and heavy. So while the eight-year old could open them, he had trouble closing them. 

The long wheelbase offers unrivalled legroom in the back and that meant my wife and I could put our own seats back further for our own comfort -even with a baby seat behind us.

Enormous door pockets, a giant centre console storage area, cupholders in all three rows, USB ports, wireless phone charging and in our case an optional domestic power outlet ($130) made this a comfortable, roomy, well equipped cabin.

Sure, the third row isn’t exactly spacious, but I’ve never met one that is. 

The intelligent seat folding system is remarkable. From the boot or side doors you can electronically adjust the second and third rows - either to raise them or lower them so they are flat for storage.

With all seats in place there is 229 litres of cargo space still left in the boot, but with those back seats folded flat you have 713 litres of capacity - and that’s just up to the cargo cover. 

The Range Rover Autobiography has air suspension and this means the SUV can lower itself to an 'Access' height to make it even easier to get in and out.

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 power and torque figures aren’t the only numbers that have risen sharply, with the GLC63 clearly impacted by a double whammy of inflation and the usual new-car price rise.

The GLC63 now starts at more than $191,814 for the SUV and $198,415 for the Coupe, which represents a nearly $30k increase over the old V8-powered model, which was priced at $164,600 just two years ago. Even for luxury car buyers that’s a big jump, especially when you’re trying to convince people of the merits of the four-cylinder powertrain. 

That also means it's more expensive than all of its key competitors, including the BMW X3 M Competition, Maserati’s Grecale and the outgoing, petrol-powered Porsche Macan GTS.

To help explain some of this price increase Mercedes-Benz Australia has opted for a high level of standard specification for local cars. Standard equipment includes 21-inch alloys, AMG composite braking, a panoramic sliding sunroof, a unique AMG steering wheel, power-adjustable sports seats in Nappa leather, a head-up display, dual-zone climate control, wireless smartphone charging and a Burmester 3D Sound system.

Also included is the AMG Track Pace suite, for those who want to unleash their GLC on the racetrack.

There’s also a limited run, AMG Edition 1 Package available too, for an additional $12,900. On the outside you get Manufaktur graphite grey magno paint, foiling with colour gradation and large AMG logo on the sides, an AMG Aerodynamics Package, unique alloy wheels with Edition 1 and AMG branding, yellow brake calipers and an AMG fuel filler cap in silver chrome with AMG lettering. 

Inside there’s AMG Performance seats, AMG Nappa leather in black with yellow contrasting stitching, AMG illuminated door sills,  carbon-fibre AMG trim highlights, yellow seat belts and a unique AMG Performance steering wheel wrapped in carbon-fibre and microfibre.

The 4.4-litre twin-turbo petrol V8 is a perfect match for the Range Rover Autobiography.

There’s enormous power at 390kW and a colossal 750Nm of torque, but it’s delivered so smoothly and without sounding like Armageddon is beginning.

You might here the engine referred to as the P530. That signifies it’s petrol and makes about 530 horsepower. 

All that grunt means that despite weighing more than 2.7 tonnes, this SUV can hurl itself from a stand still to 100km/h in 4.8 seconds. 

An eight-speed automatic sends the drive to all four wheels. And making this SUV incredibly capable off-road is an excellent four-wheel drive system with a low range gear, plus a maximum ground clearance (thanks to the adjustable air suspension) of 283mm and a wading depth of up to 900mm.

There is a six-cylinder diesel, but if you decide on that instead of the V8 then it's all over between you and me. That’s how good this V8 is.

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.

Now, you’re going to use a lot of fuel. But that’s okay because this will probably be your last petrol car and the next one will be electric so let’s go out with a bang - last drinks at the petrol bar! Land Rover says you’ll use 11.8L/100km.

After a week of punishing my Range Rover with school drop offs, shopping centre car parks, hilly suburbs, motorways and rural roads the petrol pump told me we’d used 19.8L/100km.

I’m not shocked by that consumption. This is a 2.7 tonne all-wheel drive twin-turbo V8 SUV that was almost always ferrying around four people with a pram, garden supplies and shopping in bumper to bumper traffic. A real world fuel test. 

There is that six-cylinder diesel and a hybrid version of the Range Rover, but this V8 engine suits the character of the SUV perfectly - anything else and it’s like eating reduced fat ice cream.

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.

Driving the V8-powered, long-wheelbase, 2.7-tonne, Range Rover Autobiography is a lot easier than it sounds. Really, it’s the Range Rover’s height above sea level which will strike you first.

You’ll lord it over other cars. The length doesn’t come into it - even for parking because the visibility is so good, the steering is so light and the engine is civilised and smooth.  

This is truly an easy and enjoyable SUV to drive, with power and performance whenever you need it. 

There are several drive modes from a 'Dynamic' sporty one, which makes the engine more responsive and suspension firmer, to off-road settings.

Most of the time I left the Range Rover in 'Comfort' mode for the softest ride, but with 530 horsepower lurking in the background ready to jump out and eat up hills and overtaking.

The front seats are wide, comfortable and supportive even after hours of driving. 

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 GLC63 comes standard with a comprehensive suite of safety features including 'Distronic' (Mercedes’ name for adaptive cruise control), 'Active Lane Keeping Assist', 'Blind Spot Assist', 'Traffic Light Assist' and 'Adaptive Highbeam Assist'. It also includes Mercedes’ 'Pre-Safe' accident anticipation system - which pre-tensions the seat belts and will even play a white noise to protect your ears if it senses a crash is imminent.

A parking system that includes a 360-degree camera and active parking assist is also included.

The GLC range was awarded a five-star ANCAP rating in 2022, which pre-dates the latest testing protocols, so doesn’t provide a like-to-like comparison for vehicles tested after that date.

The warranty is good with five-years and unlimited kilometre coverage.

There’s also five years roadside assistance and a complimentary five-year/130,000km service plan.

Yep, that's complimentary, as in free servicing for five years. I didn’t believe it myself and called Land Rover to check and was told that it does indeed mean free-of-charge.

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.
