Summary
BMW X6
First launched in 2008, the BMW X6 created history (and a new car category) with its coupe styling on an SUV framework.
It was a polarising effort but one that opened up the SUV market for those wanting the size and presence of an SUV without compromising on the sporty styling of a smaller car.
The 2024 X6 has had a facelift and that brings a more athletic and robust kerb-side appeal that might swing a few fence sitters onto the side of liking it.

The already pleasant interior has been polished with extra customisations available on trims and accents. The technology has seen the biggest upgrade and it now features a more streamlined mild-hybrid component to the engine. It all positions the X6 well and truly within the rank of luxury.
For the last week I’ve been driving the mid-spec xDrive40i M Sport variant to see how the facelifted model holds its own against rivals, the Audi Q8 55 TFSI Dynamic Black and Mercedes-Benz GLE450 4Matic Coupe.

Mercedes-Benz G-Class
Just like smoking, base jumping and shooting rounds off in a firing range the Mercedes-AMG G63 really shouldn’t be allowed… but dammit it’s fun. Super capable over tough terrain and a bullet on the road this top-ranking G-Wagon is the rock star of the AMG line-up.
Now, you may think this new-generation G63 looks just like the old one, but it’s completely new and fun and expensive and ridiculous.
We piloted the G63 for the first time on Australian roads at its launch. So, what’s this tall, imposing SUV like to drive? Is the cabin as spacious as it may appear from the outside? And yes, it’s fast in a straight line, but what happens when you get to a corner?

Verdict
BMW X68.3/10
I was not expecting to like the BMW X6 xDrive 40i M Sport as much as I do. The styling is still polarising but the facelift will throw more people towards the liking rather than disliking side of the fence. The cabin and boot are super practical and the X6 nails all the premium elements you expect at this level. It’s driving and handling are what win me over, though.
My son loves this one and doesn’t want to hand it back. My husband also noted how nice he thought the X6 was… and that’s saying something for a born and raised 'country boy'!
Mercedes-Benz G-Class8.3/10
The Mercedes-AMG G63 shouldn't exist, but I'm glad it does. The previous generation was loud and fast, but had its flaws with poor ride and handling. This new gen G63 now rides comfortably and handles like a hero, while staying fast, loud and fun.
Is the G63 the ultimate SUV? Tell us what you think in the comments below.
Design
BMW X6
SUV coupe styling with its raised platform and pinched bum just doesn’t do it for me usually but I like it on the new X6 model. The facelift helps the X6 appear more athletic and just plain meaner than the previous version.
The front end sees the most change with new adaptive LED headlights and a bigger 'kidney' grille. The kidneys are illuminated, which adds to its night-time presence and the extended blacked-out intake vents at the front and around the car make it look sharp as hell.
The weird prong on the side mirrors has been dropped in favour of a more seamless design (hurrah) and the 22-inch alloy wheels give total va-va-vroom sport-vibes.
On the interior, the dashboard has been revamped with a more pronounced shape and a curved display panel that houses the 12.3-inch digital instrument cluster and 14.8-inch multimedia system.
The air-vents now blend more into the dash but the little knobs for them might not be everyone’s cup of tea.
The ambient lighting is customisable and the quilted seats look beautiful but purists will wince on learning it’s synthetic leather, especially at this price point, but it feels and looks very nice.
Mercedes-Benz G-Class9/10
You know something looks interesting when people can't agree on whether it’s attractive or not. The CarsGuide office is divided on the new G63’s appearance with most saying it’s hot, but with a couple violently opposed to its looks.
Not that the new G63 looks different from the previous model, but that’s intentional. Mercedes-AMG knew the boxy personnel carrier-like shape was a massive part of this SUV’s appeal. The look has barely changed in 40 years. You could go back to the year 1979, push somebody into a time machine and when they fell out in the present day the first thing they’d say is: “Oh look, a G-Class”.
Despite the appearance that nothing has changed, almost everything has. The new G63 is longer, wider and taller than before at 4873mm end-to-end, 1984mm across, and 1966mm in height.
I’m 191cm tall and there aren’t many cars that I can’t stand beside and see over. Fortunately, if I even needed to wash the roof, I could hand off the side steps, which come standard and are as functional as they are good looking.
Also coming standard are the LED running lights which ring the outside of the headlight like a futuristic lining on an old-school design, so too are the LED tail-lights. The 'Panamericana' grille with its hat-tip to racing Benzes from the 1950s is also new part of standard kit. So is the tough looking side exhaust with two pipes poking out under the pronounced running boards on either side.
Our test car was fitted with the 'Night Package' which darkens the brake lights and adds the black treatment to the spare wheel cover, the bumper and mirrors. The pack also swaps the standard 21-inch wheels for 22 AMG cross-spoke matt black rims.
The G63’s interior has also been completely overhauled and updated with a dash featuring two 12.3-inch screens, which almost look like one giant widescreen display for nav and instrument cluster. The 'Exclusive Interior Plus' package box had been ticked on our test car and that brings diamond quilted nappa leather upholstery (ours was red) everywhere.
While it’s a sumptuous, luxurious, decadent cabin it’s impossible to ignore how vertical and upright the structure of the interior is – the windscreen, the dashboard, the doors - and then you spot the giant grab hold handle mounted on the glove box and you’re reminded that you’re actually in a hardcore off-roader.
The G63 is built on a ladder-frame chassis. Again, intentional. Yes, it’s the same as the Flintstones used in their car, but it adds immense rigidity, making it a mountain-eating monster on tough terrain.
Practicality
BMW X6
You know you’re in a large SUV when you slide into the X6 because the cabin has a lot of space in both rows.
But also because of the higher centre console design, you feel tucked into the car despite the higher seating position. It makes it feel far sportier than your typical SUV.
Even back rowers enjoy decent legroom and headroom, despite the panoramic sunroof and sloping roof design. Six-footers should be relatively comfortable in both rows but it's best to reserve the middle seat as a sometimes position for adults. The raised floor won’t allow true comfort for a longer trip.
Let’s chat luxury because there’s plenty to be had with the electric front seats and their cloud-like comfort.
The electrically-adjustable side bolsters and adjustable lumbar support makes it feel like you’re being cuddled by the seat and also hold you in place in a turn. The extendable under-thigh supports minimise leg fatigue on a longer trip.
However, the back seat is almost as comfortable as the fronts in terms of cushioning. You also sit in, rather than on top of the seats which is a nice change for an SUV.
Individual storage is great in both rows and up front you get a dual-opening middle console, glove box and a handy utility area that houses the cupholders and two phone pockets.
There is also a storage nook on the driver’s side that will comfortably hold a wallet.
In the rear you enjoy two map pockets on the front seat backs and retractable cupholders in the fold-down armrest.
The armrest houses a shallow device holder and sits at a good height. Both rows enjoy deep storage bins in each door and a large drink bottle holder.
Happily, the holder is tilted towards the user, rather than away which is what you usually see.
The boot is a great size at 580L with all seats in use. There’s a little lip that has practical metal scuff plates but otherwise the loading space is level.
The hands-free powered tailgate is welcome and the handy 40/20/40 split on the back row opens up your storage options.
You get a temporary spare tyre underneath the floor and it’s cool how the floor has a gas strut, which makes the area much easier to access.
The concertina-style cargo cover is a bit dicky to use but I like how solid it is. It could easily double as a shelf by itself.
Charging options are abundant with a total of two 12-volt ports, a USB-A port, three USB-C ports and a wireless charging pad to choose from throughout the car. But it is annoying to use the pad when the front cupholders are in use.
I like having hardened kickplates on the backs of the front seats because my seven-year old loves putting his feet on everything.
The higher ground clearance makes this an easy car to get in and out of but it also makes for a great view for my son. He finds the doors a little heavy to close but the massive door grab handles help!
Amenities in the rear row make it a pleasant space to be in for kids and adults alike. You have reading lights, map pockets, two storage shelves and directional air vents.
There is manual climate control in this row, too, but it feels at odds with the rest of the high tech in the car.
On that note, the updated technology looks gorgeous.
The head-up display is clear and the digital instrument panel offers plenty of customisation. It's a super handy feature to access your recent call log via the steering wheel controls and see it pop up on the instrument cluster.
The touchscreen multimedia system is responsive but you can also use the rotary dial to get around it. There is a stack of information in it, though, which will take a bit to get your head around. Can’t fault its graphics, it looks hot, but some users may feel flustered at first.
The system has built-in satellite navigation that features an augmented reality feature, which overlays dynamic instructions on the video feed. What makes it practical is how it can be viewed on your instrument cluster, which means more on-road focus for the driver.
There is wired Android Auto and wireless Apple CarPlay, with the latter being simple to connect to. You don’t have the important climate control buttons/dials up front and I find it annoying to access the multimedia screen to change climate and fan speed settings.
What you lack in controls there is more than made up for in the centre console. There are a lot of buttons, from the push-button starter, rotary control wheel and everything in between.
Even after a week, my mind still has a mini freeze looking at them while on the go.
Mercedes-Benz G-Class7/10
The G63 may not be as spacious as you think it is. While the ceiling is high, legroom can feel a bit restricted in the front and the back.
Riding shotgun I needed to have my front seat brought back almost to its limit so my legs didn’t feel cramped in the footwell. And while, at 191cm tall, I can sit behind my driving position with room to spare – it’s really thanks to the carved-out driver’s seat back.
Cargo capacity is far from enormous at 454 litres, but that boot space is more usable than most SUVs because of the square dimensions.
There’s a 12-volt power outlet in the front, second row and cargo area, while there are two USB ports in the centre console bin and a charging USB port in the second row.
That centre console bin is enormous and the rest of the storage places are great through the cabin with large door pockets and cupholders in the front and second rows.
Price and features
BMW X6
There are three variants for the X6 before you jump up to the performance M grade. Our test vehicle is the mid-spec xDrive40i M Sport model and will cost you $144,900 before on road costs.
That places it in the middle of its rivals and you get a well-specified model for the price tag but our test vehicle has also been fitted with a few extras, like the 'M Sport Package Pro' which adds a darkened grille and accents throughout the car, an M Sport exhaust system, red M Sport brake calipers and the M Sport signature colour stitching in the seat belts. All of that adds $2308.
Our test model also has the 'Enhancement Package' which tacks on $4616 but you get some great items like the crystal glass accents on the rotary dial and push-start button and a premium Harman Kardon surround sound system.
It also adds big 22-inch alloy wheels, a tyre pressure monitoring system and a temporary spare tyre which replaces the standard run-flat tyres on the base model.
Oh, and the 'M Brooklyn Grey Metallic' paintwork adds $1539. Just sayin’ it will cost you a pretty penny but it’s not outrageous for a luxury SUV.
Other standard equipment includes synthetic leather trims, electric front seats with heat function, electrically adjustable steering wheel, sports paddle shifters, M Sport styled scuff plates and badging, exterior puddle lamps and a full suite of LED lights including adaptive headlights.
You also enjoy a panoramic sunroof, adjustable lumbar support on both front seats, as well as extendable under-thigh support.
The drivers seat features two memory positions and comfort entry/exit functions (the seat and steering wheel slide back for you to get in and out of car).
For practicality, there is a hands-free powered tailgate, pre-entry climate control with programable entry time and a boot floor that features a gas strut for easy access.
We’ll touch on the tech later but the highlight is a new curved display panel that houses the 12.3-inch digital instrument screen and 14.8-inch touchscreen multimedia system.
Mercedes-Benz G-Class8/10
The new G63 lists for $247,700, before on road costs, which is about $12K more than the previous model, but you’re gaining a completely new SUV with improvements in the form of two 12.3-inch screens for your instrument cluster and media, there’s the Burmester 590w 15-speaker stereo, automatic parking, AMG sports exhaust, proximity key, nappa leather interior, sat nav, TV tuner, Apple CarPlay and Android Auto, three-zone climate control, heated front seats and 21-inch alloy wheels.
The Edition 1 G63 will costs you another $19,500 on top of the list price but includes the 'Night Package' which brings the black elements along with the 'Exclusive Interior Plus' package and an interior which adds carbon-fibre trim.
Under the bonnet
BMW X6
The xDrive40i M Sport has a 3.0-litre, inline six-cylinder turbo-petrol engine with maximum outputs of 280kW and 540Nm. That’s 30kW and 90Nm up from the previous model.
It has a smooth eight-speed auto transmission and is all-wheel-drive.
The facelift sees the addition of a new mild-hybrid system which makes for almost imperceptible stop/start functionality when idling and a smidge better on-road fuel economy.
With a 0-100kmh sprint time of 5.4-seconds, it’s obvious that it has plenty of power to have fun with.
Mercedes-Benz G-Class10/10
New engine, more grunt. Gone is the old 5.5-litre V8 turbo and in is the new twin-turbo 4.0-litre V8 (the same engine used in the Mercedes-AMG GT) with stacks more torque and the same power, at a whopping 430kW and colossal 850Nm.
How fast is the new G63? First, can I point out it weighs 2.5 tonnes, so take that into consideration. Second, it can nail 0-100km/h in 4.5 seconds. That is incredible.
Shifting gears seamlessly is a nine-speed automatic transmission.
The G63 is four-wheel drive and has three 100 per cent differential locks and low-range gearing.
Efficiency
BMW X6
Expectations for a thirsty engine were high, considering the hefty power available, but this version of the X6 has proved to be quite economical.
The xDrive40i M Sport variant has an official combined cycle fuel economy figure of 9.3L/100km but my real-world usage averaged 8.8L/100km.
That’s after mostly open-road driving with only a little ‘city’ thrown in but I didn't hesitate to use the power, so I'm happy with the result.
The X6 has a big 83-litre fuel tank and based on my usage, you’d see a driving range of around 943km, which is great.
BMW only recommends a minimum 95 RON petrol to be used.
Mercedes-Benz G-Class7/10
Oh, come on, you don’t want to know this… skip to the next section.
You’re still here. Okay then, it’s 13.1L/100km over a combination of urban and open roads. That’s under ideal conditions, too. Our car was going through premium unleaded at about 16.0L/100km. Good thing is you have a 100-litre fuel tank.
Driving
BMW X6
The X6 is a thoroughbred on the road. It’s wide stance and massive wheels provide a well-balanced and grippy on-road ride experience.
Seriously, the tyres feel glued to the road even in the wet. Confidence is high with this one.
There is plenty of power to enjoy and you don’t feel like you’re digging deep for it, either, when you have to get up to speed or overtake.
It has the handling and power of a much smaller and sportier car but at no point does it feel wild or reckless to drive. It’s got a certain elegance and maturity to its handling.
Despite those massive wheels, the ride comfort is fantastic with the adaptive suspension. You still feel the road but you’re not knocked about by it. It’s very much a driver’s car in that sense but passengers still feel well-cushioned.
The cabin is insulated and you get basically no road noise or wind noise but occasionally you get some feedback from the tyres depending on the road surface. Longer journeys are comfortable and quiet.
The steering is light enough that you don’t feel like you’re hauling a massive SUV around but is still responsive. Meaning you can tackle a winding road or urban traffic easily.
When it comes time to park it, you’ll love having the 360-degree view camera system. It’s the best and clearest system I’ve sampled.
Add the front and rear parking sensors and no car space is an issue. But if you’re unsure, you can use the Park Assist feature to help out.
Mercedes-Benz G-Class9/10
Have you ever driven a G-Class before? Nope, well then have you ever ridden an elephant, then? Passed time hanging out on the roof of your house just drinking beer? Sat on somebody shoulder’s in a game of swimming pool volleyball?
Okay, well you feel very high up and the bonnet stretches out before you like the hood of Mack truck, and that’s when you realise those weird-looking indicators on the guards double as signposts letting you know where the edges are.
But even then, it doesn’t feel big to drive, even the cabin feels a bit tight up front.
What it does feel is fast. Very fast. Dab the accelerator and the nose rises up and you better be pointing in the direction you want to go, because hold the pedal down and the G63 will yank you down the road at warp speed.
Acceleration isn’t supercar brutal by any means, but how it gets there is roaring through that side exhaust like a Viking running into battle, after waking up on the wrong side of the bed. With the windows down its deafening, but in good way.
Complaints about the old G63 centred around steering, ride and handling or more specifically the absence of those three things. In this new generation G63 those pain points have been addressed by replacing articulating ball steering with electric power steer, swapping the live front axle for independent front suspension and revising the chassis rails.
Now, the G63 can go around corners – incredibly well. Our test track was Victoria's Great Ocean Road, and if we were in any other large SUV, they would have been fishing us out of Bass Strait.
Steering is now accurate and progressive; the front end feels pointable and light.
Comfort drive mode is too comfortable for me, giving the ride a wafty bounce. Sport mode firms the dampers for good handling but keeps the ride comfortable, which adding weight to the steering. Sport Plus firms the adaptive dampers further and combines great cornering without an unbearable ride.
The G63 isn’t a vicious animal unlike some big grunt sports cars, but you have to keep reminding yourself you can’t drive it like one. Not because it will bite you, but because it’s 2.0-metre tall, 2.5-tonne metal box. A hilariously fun one.
Safety
BMW X6
The X6 has an extensive safety list and I like the SOS emergency call button and front cross-traffic alert. Both are great to have but the latter is particularly useful on a large SUV like this, especially in the city or driveways.
Other standard safety equipment includes blind-spot monitoring, autonomous emergency braking, LED daytime running lights, forward collision warning, side collision warning, rear cross-traffic alert, lane keeping aids, lane departure warning, intelligent seat belt reminders, front and rear parking sensors, 360-degree view reversing camera, traffic sign recognition, driver fatigue monitor, and adaptive cruise control with stop and go functionality. As well as an SOS emergency call button and stolen vehicle tracking.
The X6 hasn’t been tested by ANCAP, so it’s unrated but it is based on the X5, which achieved a five-star rating in 2018. However, it only features six airbags which is low for a family car.
There are ISOFIX child seat mounts on the outboard seats and three top tethers in this row. Two seats will fit best but I reckon you could squeeze a third in if you had to.
There’s plenty of room for front passengers when you install a 0-4 rearward facing child seat, too, which is good.
Mercedes-Benz G-Class9/10
The G63 has the maximum five-star ANCAP rating and along with nine airbags comes with AEB, lane keeping assistance, blind spot warning, traffic sign recognition and adaptive cruise control.
For child seats you’ll find three top tether points and two ISOFIX mounts across the second row.
Obviously, there’s a full-sized spare wheel. Don’t make me point it out.
Ownership
BMW X6
The ongoing costs are surprisingly reasonable for a large luxury SUV! Like its rivals the X6 enjoys a five-year/unlimited km warranty.
However, you can pre-purchase a servicing plan for up to five years or 80,000km, whichever occurs first, for a flat $2400. Or an average of $480 per service which is inexpensive for this class.
Service intervals are also good at every 12 months or 15,000km, whichever occurs first.
Mercedes-Benz G-Class7/10
The G63 is covered by Mercedes-Benz’s three-year/unlimited kilometre warranty. The pricing plan for servicing will cost you about $4000 over three years.
