Mercedes-Benz GLS-Class vs Mini 3D Hatch

What's the difference?

The GLS63 is an intimidating beast from afar, but it rewards its occupants in almost every way. Yep, there really isn’t a box it doesn’t tick without serious compromise, such is its breadth of capability.

If there was ever a Swiss Army Knife of cars, the GLS63 is definitely a contender for the title, one that makes it very hard to wipe the smile off your face. Just make sure you can fit it in your garage first…

The Mini 60 Years is another classic special edition Mini and its definitely one for the fans. I'm not at all fussed by it and would quite happily save my money for a standard Cooper S. The Mini is still one of the most playful, interesting cars from a mainstream car maker and while it doesn't please everyone with its size and weight, it's tremendous fun to drive.

It's the kind of car I could own and I always feel comfortable in - it's the perfect size for urban environments but is just as much at home belting down a freeway on a long trip or scooting down a B-road just because.

If the GLS63 was a Marvel superhero, it would undoubtedly be the Hulk. Simply put, it has road presence like few others. In fact, it’s frankly menacing.

Of course, the GLS is already pretty intimidating due to its sheer size and blocky design, but the GLS63’s full-fat AMG treatment takes it to another level.

Naturally, the GLS63 gets an aggressive body kit, with its purposeful bumpers, side skirts and rear spoiler serving as instant reminders of what you’re dealing with, but it’s AMG’s signature Panamericana grille insert that really hammers home the point.

Around the side, the GLS63’s 22-inch alloy wheels with staggered tyres (front: 275/50, rear: 315/45) make their presence known, positioned below the wheelarch extensions.

That said, some fun’s also had at the rear end, where the GLS63’s diffuser element integrates the foreboding sports exhaust system with quad tailpipes very neatly.

The focused Multibeam LED headlights also look the part, while the opposing LED tail-lights tie everything together outside quite nicely.

Inside, the GLS63 stands out from the GLS crowd with its sports steering wheel with Dinamica microfibre accents, and multi-contour front seats, which are covered in Nappa leather alongside the armrests, dashboard and door shoulders and inserts.

Of note, the doors bins are unfortunately of the hard plastic variety, which is very disappointing in a vehicle that costs this much. You would expect that cow hide would also been applied to them, but alas it isn’t.

The GLS63’s black headliner serves as an obligatory reminder of its sporting intent, and while it makes for a dark cabin, metallic accents are prominent throughout, while the optional trim (our test vehicle had carbon-fibre) mixes things up, alongside the ambient lighting.

And let’s not forget the GLS63 is still loaded with plenty of cutting-edge technology, including a pair of 12.3-inch displays, with one the central touchscreen and the other the digital instrument cluster.

Both are powered by Mercedes’ class-leading MBUX multimedia system and feature Apple CarPlay and Android Auto support. This set-up arguably remains the best there is today thanks to its speed and breadth of functionality and input methods.

Always readily identifiable, Mini updates always add detail without touching the main game. I quite like the indicators, which are big LED rings surrounding the headlights, but then again I'm a sucker for lighting. I think the Mini looks terrific in three-door form and the Union Jack rear lights have grown on me. They're a bit silly but in a good way, which kind of sums up the car. The British Racing Green looks pretty good, too. Amusingly, the puddle lamp even has a 60 Years flavour.

You can spot the Cooper S by the centre exhaust and the 60 Years has its own set of 17-inch alloys.

The cabin is pretty much the same apart from the particularly warm hue of the leather. It's a classic colour for British cars but works nicely. In the Cooper S, the panoramic sunroof is split in two, but the front section opens. It does make the car feel a bit bigger, which is handy given it's pretty tight in there. The piping is a nice touch, too, although the Piano Black on the dash was so last decade rather than so last century but at least there isn't a slab of tacky wood. The fact the interior is otherwise unchanged means there are other cheap touches that somehow fail to ruin the ambience.

Mini calls its version of iDrive 'Visual Boost' for some reason, and it's displayed via a 6.5-inch screen set in a big round dial ringed by changeable LED lights.

Measuring 5243mm, 2030mm wide and 1782mm tall with a 3135mm wheelbase, the GLS63 is an upper-large SUV in every sense of the term, which means it’s also very practical.

For example, cargo capacity below the load cover is decent, at 355L, but stow the 50/50 power-split-folding third row via the boot and it’s very good, at 890L, or drop the 40/20/40 power-split-folding middle bench, too, and it becomes a cavernous 2400L.

Better yet, the boot’s aperture is almost square, and its floor’s flat, while there’s no load lip to contend with, making loading bulkier items even easier. Up to four tie-down points are also on hand (depending on seating configuration) to secure loose cargo.

Under the false floor is the space-saver spare, which is to be expected, but what isn’t expected necessarily is the fact there’s also enough room there for the cargo cover when it’s not in use, which would be the case if six or more passengers are regularly onboard.

Moving into the power-sliding second row, the GLS63’s practicality is once again brought to the fore, with up to six-plus inches of legroom available behind my 184cm driving position.

There’s also two inches of headroom with the panoramic sunroof in situ, not to mention just enough toe-room. The GLS63’s small transmission tunnel and sheer width also mean three adults can be seated on the middle bench with few complaints.

Amenities-wise, the second row has map pockets on the front-seat backrest and a small fold-down cubby below the rear climate controls, with it containing two slots for smartphones and a pair of strategically placed USB-C ports.

The rear door bins can take one large bottle each, while a fold-down central armrest is also on hand, featuring a shallow tray and retractable (and flimsy) cupholders.

Alternatively, the $2800 Rear Seat Comfort Package fitted to our test vehicle subs in a tablet that can control the multimedia system, a wireless smartphone charger and a small cubby into the former, as well as a heated/cooled cupholder atop the rear of the centre console.

In the third row, it’s not quite as roomy if you’re an adult. With the middle bench in its most accommodating position, my knees still brush up against its backrest, which is to be expected given it’s primarily designed for children. I also have an inch of headroom there.

Nonetheless, getting in and out of the third row is relatively easy as the power-operated middle bench tumbles forward and provides just enough space to make entry and exit somewhat graceful.

When seated, rear occupants are treated to two USB-C ports and one small cupholder each, so they’re arguably taken better care of than those in the middle.

Child seats are well and truly accommodated, with four ISOFIX and five top-tether anchorage points fitted across the second and third rows, although the latter will inevitably prove to be a much tighter fit.

The driver and front passenger are still taken care of, with a front cubby taken up by two heated/cooled cupholders, a wireless smartphone charger, two USB-C ports and a 12V power outlet, while their door bins take one large and one small bottle each.

In-cabin storage options include the large central storage bin, which hides another USB-C port, while the glovebox is on the smaller side, with about a third of it taken up by the fragrance, which is pumped into the cabin to ensure the interior always smells its best.

Yep, it's a small car so expect things to be reasonably cosy. I fit in there fine but I am neither particularly tall nor broad. Taller folks will fit just fine in the front (but not too tall, don't be greedy) while larger people might find themselves uncomfortably close to their passengers.

The rear seat is bearable for children and patient adults on short trips. At least they'll be well hydrated because as well as the pair of cupholders up front there are a further three in the back for a total of five. The Mini joins the NC Mazda MX-5 as a car with a greater cup capacity than passenger capacity. Front seat passengers can keep the water topped up as there are also small bottle holders in the doors.

There are two USB ports in the front seat and a wireless charging pad that doesn't fit bigger phones under the armrest. If your iPhone is the smaller size, the combination of wireless CarPlay and charging pad is excellent.

The boot is surprisingly big for such a small car, beating many of its cheaper rivals with 211 litres with the seats in place and 731L with them folded down.

There are four ways you can have your 60th Anniversary Mini. If you're happy with 1.5-litres of power, there is the three or five-door Cooper for $33,900 and $35,150 respectively. If you want a bit more grunt, you can step up to the Cooper S three-door (the car I had) for $43,900 and the five-door for $45,150. Eagle-eyed readers who know their Mini pricing will see a price rise of $4000, and Mini Australia says you get $8500 of value. All of those prices are before on-road costs. 

The standard Cooper S package brings dual-zone climate control, keyless entry and start, driving mode selection, leather interior, reversing camera, sat nav, auto LED headlights and wipers, wireless Apple CarPlay, run-flat tyres and you can add all the 60 Years stuff on top of that.

Without putting too fine a point on it, the Mini isn't cheap to begin with, so whacking four grand on top of the already stiff pricing obviously doesn't improve matters. You do get more stuff, obviously, as suggested by the claimed $8500 figure.

That means British Racing Green IV metallic paint with Pepper White mirrors and roof or Midnight Black Lapis Luxury Blue with black mirrors and roof. Inside you get a choice of Dark Cacao with the green paint or Carbon Black with the blue paint. If you choose the latter you miss out on the special piping and details.

Cooper S buyers pick up wireless phone charging, Comfort Access pack, heated front seats and LED headlights while the Cooper S adds a panoramic sunroof, Harmon Kardon-branded system and head-up display.

The GLS63 is powered by a familiar 4.0-litre twin-turbo V8 petrol engine, with its version producing a thumping 450kW of power at 5750rpm and 850Nm of torque from 2250-5000rpm.

This unit is mated to a nine-speed torque-converter automatic transmission and AMG’s fully variable 4Matic+ all-wheel-drive system with torque vectoring and a rear limited-slip differential.

This set-up also features Mercedes’ EQ Boost 48V mild-hybrid system, which actually gives a 16kW/250Nm electric boost in short bursts, such as when accelerating off the line.

Speaking of which, the GLS63 sprints from a standstill to 100km/h in just 4.2 seconds, while its top speed is electronically limited to 250km/h.
 

The Cooper S has the usual 2.0-litre turbocharged four (the Cooper has a 1.5-litre turbo three-cylinder), serving up 141kW and 280Nm. Power finds its way to the front wheels via a seven-speed twin-clutch transmission and will push the 1265kg Cooper S to 100km/h in 6.8 seconds.

The GLS63’s fuel consumption on the combined-cycle test (ADR 81/02) is 13.0L per 100km, while its carbon dioxide emissions are 296 grams per km. All things considered, both claims are unsurprisingly high.

In our real-world testing, we averaged a fearsome 18.5L/100km over 65km of driving, split between highways and country roads, so not your usual mix. A very heavy right foot definitely influenced that result, but don’t expect to do too much better in a normal run.

For reference, the GLS63’s 90L fuel tank can be filled up with 98RON petrol at a minimum.

Mini reckons you'll get 5.6L/100km on the combined cycle. Maybe you could if you don't drive it like I did (I got an indicated figure of 9.4L/100km).

The Mini has stop-start to help cut fuel use around town and launch control to ruin those efforts.

Frankly, the GLS63 has absolutely no right being as capable as it is. It’s a really big bus that’s legitimately convinced it’s a sports car half its size.

Being a GLS variant, the GLS63 has independent suspension consisting of four-link front and multi-link rear axles with air springs and adaptive dampers, but its party trick is the addition of active anti-roll bars.

In what feels like magic, the GLS63 is simply not intimidated by corners, despite having massive dimensions and a considerable 2555kg (kerb weight) to deal with.

The active anti-roll bars make the GLS63 so much easier to drive fast through the twisty stuff, almost eliminating body roll, taking one key variable out of the equation for the driver. Active engine mounts are also fitted, helping to settle things even further.

The electric power steering on hand is also good. It is speed-sensitive and has a variable ratio, which basically makes the set-up more direct when it needs to be. It’s typically light in hand, too, until one of the sportier drive modes is engaged and extra heft is added.

So, handling is scarcely believable, which means the ride must be compromised, right? Yes and no. With the adaptive dampers in their softest setting, the GLS63 is very compliant. In fact, we’d say it feels luxurious when compared to other high-performance SUVs.

That said, our test vehicle was fitted with the optional 23-inch alloy wheels ($3900), which look the part but expose sharp edges and other road imperfections, not to mention generate noise easily heard inside. Naturally, feedback is exacerbated in the sportier drive modes.

Anyway, there’s more performance, and the GLS63 has the rest in spades. Its engine is a powerhouse in every sense of the word. It’s so powerful, in fact, that it hilariously hunkers down off the line or when suddenly accelerating at low speed.

Thanks to the mild-hybrid system, wads of torque is available from the get-go, making for a highly responsive driving experience, even in those rare moments when the engine isn’t on song.

While not as characterful as some of the other members in the 63 series, the GLS63 still makes some thoroughly entertaining noises, with its sports exhaust system popping like mad while on the overrun.

All of this ability is very well and good, but you need to be able to pull up quickly, and the high-performance braking package (400mm front and 370mm rear discs with six-piston fixed callipers and single-pot floating stoppers respectively) mercifully does exactly that.

Driving a Mini is a unique experience. Almost no other car on sale today has the combination of that far-away, near-vertical windscreen and an A-pillar that is almost slim by today's standards. The side of the car is almost fifty percent glass, so vision is terrific. 

It had been a little while since I drove a Mini Cooper S so I was looking forward to the Mini bounce that I've always loved and my wife despised. Somewhere along the way, that bounce has faded somewhat, to the point where my wife says she doesn't mind it anymore. That must be a good thing, because while the ride is more refined, it's still a blast to drive, even if you're just getting around in traffic.

The Mini just loves point and squirt driving. The quick, well-weighted steering helps you swing the nose in and out of gaps and the handy slab of torque from the 2.0-litre ensures you stay out of trouble while doing it. The Mini also loves haring down a country road, the more secure-feeling ride belying its short wheelbase. The weight of the car probably helps keep things on the straight and narrow. It's pretty clever to make the car feel grown-up while also maintaining its sense of playfulness.

The driving mode switch doesn't make a huge amount of difference, with Sport mode adding a few apologetic pops from the exhaust.

Complaints are few, but there are too many buttons on the steering wheel and to my mind are all in the wrong place. By necessity, the controller for the media screen is practically on the floor and is crowded in by the cupholders and huge handbrake lever. But that doesn't mean Mini should take away the handbrake.

I have my reasons.

Like the rest of the range, the 60 Years has six airbags, ABS, stability and traction controls, forward collision warning, AEB (auto emergency braking), a reversing camera, speed sign recognition, and tyre pressure monitoring (it also has run-flat tyres and no spare, so that's an important consideration).

There are two top tether and ISOFIX points for the kiddies.

The Mini scored four out of a possible five ANCAP stars in April 2015. This was before AEB became standard earlier in 2019.

As with all Mercedes-AMG models, the GLS63 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.

The GLS63’s service intervals are relatively long, at every 12 months or 20,000km (whichever comes first). Better yet, it’s available with a five-year/100,000km capped-price servicing plan, but it costs $4450.

As with parent company BMW, Mini only offers a three-year/unlimited kilometre warranty with roadside assist for the duration. You can buy an extension to five or hold your breath during negotiations with a dealer.

Servicing is condition-based - the car will tell you when it needs one. You can buy a servicing package that covers the basics for five years for about $1400 or step up to the near-$4000 option which throws in consumables like brake pads and wiper blades.
