Mercedes-Benz GLC-Class vs Mini Countryman

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 new Mini Countryman John Cooper Works in Favoured trim offers everything you’d expect it to - the iconic Mini styling, a powerful driving performance and a well-equipped cabin. It’s a wonderfully quick urban dweller that you can park anywhere but is just as happy on the open-road. For me, this is pure fun and offers more personality than a lot of its rivals.

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.

It's a case of the 'not-so-mini' when it comes to the new Countryman because it now stands at 4447mm in length, 1843mm in width and 1645mm in height. That's 170mm longer and 21mm wider than the previous generation!

But the Countryman still has all of the fun styling you’d expect in a Mini and it’s that iconic styling that sets this car apart from its rivals. It knows its fun and isn't afraid to show it.

Our Mini Countryman gets JCW badging across the body of the car, including its wheels but it's the chequered flag motif across the grille that reminds you what’s under the bonnet.

Unfortunately, our test model is finished in the rather boring 'Midnight Black II' but the range of colours and customisations available on the Countryman will help make it feel like your own.

Head inside and there's a hefty mix of materials in the cabin space. You’ve got a thick and rough-textured weave/knit across the dash, doors and tops of the sports seats but that’s then mixed with a black synthetic upholstery and plastics everywhere else.

The red stitching and accents won’t land with everyone but it certainly creates a fun atmosphere.

There are some lovely design highlights with rose gold metal accents in the door handles and air vents. A panoramic sunroof adds some much needed airiness and I adore the way you still get a ‘turn-key’ experience despite having keyless start with the starter knob.

The round media screen isn't as well-integrated as before but it looks gorgeous and the different drive modes give you a range of colours to further customise the cabin.

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 cabin of the Mini Countryman doesn't feel like it belongs in a small SUV. The legroom is still best up front but the second row offers more than enough space for taller adults. It will be most comfortable for four rather than five adults, though.

The electric front seats have large side bolstering and decent padding but they are on the firmer side. You get a little bit of fatigue on a longer trip but around town they’re great and the massage function on the driver's seat is strong.

The rear seat is even firmer than the front and set like a stadium seat, so it won't be as comfy for adults on a longer trip. The fold-down armrest adds some bolstering.

While the storage looks a little odd at first, all of the cubbies are quite functional. There's a lot of them, too, and the dual shelves underneath the starter-knob are particularly handy for your larger 'small' items, like phones and sunnies case. This is where the wireless charging pad is, too.

The glove box can fit a manual and the little centre console is kind of adorable but still fit all of my keys and wallet.

The sliding armrest is a nice touch and there's a couple of USB-C ports underneath it. There are two large cupholders, two drink holders and small storage bins in the doors.

In the rear you get a drink bottle holder in each door, two map pockets, two USB-C ports and two cupholders.

The circular multimedia screen looks great and once you get used to how the menus are accessed and the little shortcuts, it’s a fairly simple system to use while on the go.

The touchscreen is fairly responsive but you'll need to do wide swipes across to switch the menu screens.

I’m not a massive fan of having to access a screen for most of your functions but do like the way climate control remains on the screen at all times and it's just the fan function that needs a couple of extra toggles.

The multimedia system is run by Android Automotive and has wired and wireless phone mirroring. The Apple CarPlay maintained a steady connection this week with my iPhone 15 Pro Max and the built-in sat nav is easy to use.

Rounding out the interior is the large 505L boot and if you want more storage options, the back row has a 40/20/40 split-fold.

The loading space has a small lip, and a handy storage compartment underneath the floor which holds the tyre repair kit and other items you don’t want rolling around. JCWs get a hands-free powered tailgate, which is always handy after a big shopping trip.

There are five versions of the new Mini Countryman, which includes a line-up of petrol and fully-electric powertrains.

For the petrol John Cooper Works (JCW), there are two trim levels available and our test model is the flagship Favoured variant.  It's priced from $73,990, before on road costs, making it an affordable high-performance small SUV compared to its Euro rivals.

The third-gen Mini Countryman JCW is built alongside the BMW X1 and because they share the same platform and engine, it directly competes against the X1 M35i xDrive which is priced from $92,300 MSRP.

So, if its the impressive engine outputs you’re after our JCW Favoured is the better pick. The Audi RS Q3 2.5 TFSI quattro is even more expensive at $101,215 but it does have better engine outputs.

Surprisingly, the John Cooper Works Favoured doesn’t add all that much to the ‘base’ Classic trim but the additions include 20-inch alloy wheels with performance brakes (including red calipers) and six extra paintwork options. You also get electric front seats, with memory and massage functions for the driver.

JCW models come with keyless entry and start, heated front seats, a panoramic sunroof, adaptive cornering LED headlights, dual climate control, powered tailgate with kick-function, heated steering wheel and velour floor mats.

The technology includes a round 9.4-inch OLED multimedia screen, dash cam recorder, a premium Harman Kardon sound system, digital radio, a head-up display, 'Spike' Mini Assistant, an interior camera (you can take selfies!), augmented satellite navigation, wireless Apple CarPlay/Android Auto, a wireless charging pad, four USB-C ports and two 12-volt sockets.

While it's impressively more affordable than its peers, the JCW in Favoured trim misses out on a few top-grade features you'd expect at this level. Features like front seat ventilation and heated rear outboard seats or even a massage function on the front passenger seat.

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.

The JCW Countryman is an all-wheel-drive with a seven-speed dual-clutch auto transmission. It has a 2.0-litre, four-cylinder, turbo-petrol engine that produces up to 233kW of power and 400Nm of torque. This model has a 0-100km/h sprint time of just 5.4-seconds!

There are eight drive 'experience' modes you can choose from, comprising 'Core', 'Green', 'Go Kart' (very fun), 'Personal', 'Timeless', 'Vivid', 'Balance' and 'Trail'.

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.

For a performance SUV, the JCW Favoured has a lowish official combined (urban/extra-urban) fuel cycle figure of just 7.7L/100km and a large 54L fuel tank, giving you a theoretical driving range of up to 701km, which isn’t bad for such a little go-getter.

After doing a few bigger road trips this week, plus a long weekend in the city, my real-world usage has popped out at 7.9L/100km, which is excellent but expect it to be higher if you only do city 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.

Even if you don’t love the design, the power and performance of the turbo-petrol engine will win you over. It’s just pure unadulterated fun on the open road and in the city. You get a total hot-hatch experience, despite the Countryman being an SUV. 

The adaptive suspension feels a little stiff when you’re going over uneven road surfaces at higher speeds and road noise also creeps in, but around town this is a comfortable ride. 

Visibility is great, even in heavy rain with a child's car seat installed in the rear (we had a mix of weather on test). Thanks in no small part to the all-wheel drive system it felt sure-footed in the wet and I felt confident this car would do everything I asked of it.

The firm steering makes for a nimble on-road experience no matter the situation and you have gear-shifting paddles on the steering wheel.

There’s also a 'Boost' mode that wrangles the top performance out of the suspension, steering and engine for when you want more control.

You can park the Countryman just about anywhere and the 360-degree camera view system is excellent quality. It’s easy to park, even in small, tight car parks.

The new Mini Countryman hasn’t been assessed by ANCAP but features a healthy list of crash-avoidance safety features and has nine airbags, including a front centre bag.

Standard safety equipment includes driver monitoring, rear cross-traffic alert, AEB, 'Cornering Brake Control', blind-spot monitoring, emergency e-call, lane keeping aid, lane departure warning, side exit assist, a dash cam recorder, tyre pressure monitoring, 360-degree view camera system plus front and rear parking sensors.

The adaptive cruise control is also well-tuned and one of the better systems I’ve sampled recently.

The rear seat has two ISOFIX child seat mounts and three top tether anchor points but two seats will fit best.

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 Countryman is offered with a five-year/unlimited km warranty which is pretty standard fare for a Euro model. You can pre-purchase a five year or up to 80,000km servicing plan for $2250, which is very competitive for the class.

Servicing intervals are condition based, so your Mini will tell you when it needs to visit the workshop.
