Summary
BMW X5
The BMW X5 is a leading contender in the ‘Over $70K Large SUV’ division of Australia’s new car market, which is a hotly-contested segment boasting 15 marques and 25 models.
The X5 has hit an enduring sweet spot with Aussie buyers in terms of size, performance and price. BMW prefers to call it a Sports Activity Vehicle (SAV) as distinct from its Sports Utility Vehicle (SUV) rivals.
Clearly, any word association with a utility is something BMW Group Australia wants to avoid after recently launching its latest X5 range, which brings numerous enhancements including design revisions, increased standard equipment, refreshed powertrains and more.

We were entrusted with the digital ‘Comfort Access’ key to one of the latest X5s, to understand from a family car perspective why this model range enjoys such enduring popularity with prestige SUV (sorry, SAV) buyers.

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 X58.3/10
This is a luxurious prestige five-seater brimming with BMW’s latest design and technology that’s not only practical for weekly family duties but can also embrace spirited driving with the push of a button. A great all-rounder for families that like a sporty edge.
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 X5
The latest front-end design features subtle revisions to BMW’s signature 'kidney' grille theme, highlighted by slimmer matrix LED headlights with chevron-shaped DRLs that incorporate the turn indicators.
There’s also an ‘iconic glow’ function, which illuminates the twin-grilles at night in-sync with the external courtesy lights when approaching and departing the vehicle. Lower front air-intake and tail-light treatments have also been revised.
The dash features a new curved instrument panel. Based on BMW’s latest generation 'iDrive' operating system, it consists of a 12.3-inch driver’s info display and 14.9-inch control display presented across the same seamless glass surface.
The control display’s touchscreen functionality has allowed dash buttons and switches to be minimised.
This new design dash has a blend of synthetic leather trim and dark brown/high-gloss woodgrain surfaces, along with new LED ambient lighting and gear-selector design.
The rear seat is sumptuous and spacious, even for someone my height (186cm). There’s ample knee and headroom and it can seat three kids in comfort, but for adult passengers wanting that 'business class' feel it would be ideal for two.
My only criticism of the new instrument display is that with more than 30 applications displayed on the expansive control screen, it can be distracting at times trying to visually locate and operate these functions while driving.
And, depending on sun angle, there were also complaints from different front seat passengers on different days about blinding glare caused by the dash’s high-gloss woodgrain inserts. Fortunately, the driver is unaffected by these reflections.
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 X5
With its 2165kg kerb weight and maximum allowable weight of 2885kg, our test vehicle can legally carry up to 720kg.
That should be ample for five adults (even better for kids) and their luggage, of which up to 100kg can be carried on the roof rails using a rack or roof box (both in BMW's accessory range).
Powered upper and lower tailgates provide good access to the luggage area, which is carpeted and equipped with a roll-out privacy screen, load securing hooks, a 12-volt accessory outlet and a first-aid kit stored behind a removable side panel.
The space-saver spare and tools are stored below the hinged load floor, so all luggage must be removed to access them.
Internal luggage space with the rear seat upright is 650 litres (0.65 cubic metres) which expands to 1870 litres (1.87 cubic metres) with the rear seat folded flat.
A useful load-carrying feature when the rear seat’s backrest is upright is a hinged centre section that folds forward and flat to carry long and narrow items.
These can stretch all the way from the tailgate to the dash if need be, which could be handy for carting anything from skis to home hardware purchases (firmly secured, of course).
It’s also rated to tow up to an impressive 3500kg of braked trailer, which matches the class benchmark for one-tonne utes.
However, given that tow-ball download (TBD) is usually around 10 per cent of trailer weight, the X5’s maximum TBD rating of only 140kg could be a challenge if 3500kg towing is required.
Front of cabin storage includes a big bottle-holder and bin in each front door, a glove box and on the right-hand side of the dash a pull-out driver’s bin, both of which are felt-lined.
The centre console, in addition to its wireless phone-charging pad, USB-A port and 12-volt outlet, has two small-bottle/cupholders up front and a large box at the rear, housing a USB-C port and topped by a padded dual 'brochure fold' lid that double as an elbow-rest for driver and front passenger.
Rear seat storage includes a large-bottle holder and bin in each door and pockets on each front seat backrest. The rear of the centre console has two storage nooks for small items in addition to its air-vents, two USB-C ports and a 12-volt outlet. There’s also a handy tablet-mount and USB-C port on each front seat backrest, which is great for long trips.
Folding down the rear seat’s centre armrest reveals two pop-out small-bottle/cupholders. And under its hinged lid is a hidden felt-lined compartment that’s ideal for storing slim screened devices away from prying eyes.
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 X5
Our test vehicle, to use its full name, is the X5 xDrive 40i M Sport. That breaks down to xDrive (intelligent all-wheel drive) and 40i (3.0L turbo in-line petrol six) with eight-speed automatic transmission.
M Sport denotes a package that's included as standard equipment which contains desirable goodies like enormous multi-piston M Sport brakes/adaptive suspension/aerodynamics, M leather-rimmed steering wheel, high-gloss black roof-rails and more.
All up, the list price is $138,900. However, our example has an optional ‘Enhancement Package’ which for another $6000 adds your choice of selected 22-inch alloy wheels (fitted with 275/35 R22 Continental tyres on ours), a tyre pressure monitoring system, metallic paint ('Skyscraper Grey' on ours), Harman Kardon 16-speaker surround-sound audio and 'Crafted Clarity' glass application (glass-handled shifter).
And this is on top of many standard features including three-zone climate control, automatic two-piece tailgate, digital radio, a head-up driver display, adaptive LED headlights with high beam assist, a panoramic full-length sunroof, wireless Apple/Android integration, 'Verino' quilted synthetic leather upholstery, numerous USB ports/12v outlets and more. However, there’s only a space-saver spare.
Numerous options include self-levelling air suspension, 'Merino' leather upholstery, active seat ventilation and massage functions, thermo-adjustable cupholders, LED-illuminated ‘sky lounge’ panoramic glass sunroof and Bowers & Wilkins premium surround sound to name a few.
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 X5
The X5 xDrive40i is powered by BMW’s legendary 3.0-litre DOHC 24-valve in-line six with state-of-the-art technology.
This includes twin-scroll turbocharging, variable valve/camshaft timing and 48-volt mild hybrid technology (delivering up to 9.0kW and 200Nm) using an electric motor integrated with the transmission.
The combined effect is optimised power and throttle response (0-100km/h in 5.4 secs) with minimal fuel consumption and Euro 6d emissions.
It produces 280kW between 5200-6250rpm and 520Nm of torque (this can reach 540Nm with hybrid input) across a remarkably wide and flat peak torque band between 1850-5000rpm, which showcases its flexibility. There’s also auto start-stop and selectable drive modes.
This is paired with BMW’s smooth and sharp-shifting eight-speed torque converter automatic, which combines the best characteristics of a dual-clutch and traditional torque converter transmission.
There’s overdrive on the seventh and eighth gears to optimise fuel economy and the choice of rapid manual-shifting using the steering wheel paddles.
Power reaches its wide tyres through the xDrive intelligent all-wheel drive system, which actively varies the engine’s torque distribution between the front and rear wheels to optimise traction at all times.
BMW’s ‘Efficient Dynamics’ also includes brake energy regeneration with recuperation display and many other standard features to enhance driving safety and efficiency.
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 X5
BMW claims combined average (WLTP) fuel consumption of 9.9-8.5L/100km. Our 415km test comprised a mix of suburban and highway driving and when we stopped to refuel the dash display was showing 10.2L/100km which was line-ball with our own 10.6L/100km figure, calculated from fuel bowser and tripmeter readings.
So, based on our figures, you could expect a realistic driving range of around 780km from its 83-litre tank using standard 91-octane petrol.
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 X5
It’s supremely comfortable, with front bucket seats that offer powered-adjustment of height, reach and backrest angle along with side bolsters that can tighten their grip of your upper torso.
There’s also two-way lumbar support, that adjusts not only how far it pushes your spine forward but also allows that pressure point to be raised or lowered.
Combined with its power-adjustable leather-rimmed steering wheel, it would be hard not to find a comfortable driving position.
Eyelines to all mirrors are good and over-shoulder blind-spots are minimal. Front and rear occupants can talk without raised voices thanks to low engine, wind and tyre noise at highway speeds.
As you’d expect, it has high build quality and a tangibly solid feel as though it was machined from a single block of steel, from the satisfying thuds of its closing doors to the absence of shudders or rattles on a variety of roads.
It also has two personalities, which can be switched in an instant. In 'Comfort' mode it will happily cruise around city and suburbs as a mild-mannered family car, fulfilling daily duties like work commutes, school drop-offs and pick-ups, supermarket shopping and the like.
However, flick the drive mode to 'Sport Plus' and you awaken, well, if not ‘the ultimate driving machine’ then something close.
Its optimised drivetrain and handling settings feel more like a sports sedan than a family car, which can turn any winding mountain road into an engaging experience.
It has impressive reserves of cornering grip and braking force, combined with sparkling engine response and fast sequential manual-shifting at your fingertips.
It feels impressively agile, with all-round response that belies its 2.0-tonne-plus kerb weight, backed by a symphony of sounds from its sublime in-line six.
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 X5
Five-star ANCAP (awarded in 2018) includes front and side airbags for driver and front passenger, plus head airbags for front and rear seats.
The comprehensive 'Driver Assistant Professional' active safety menu includes AEB (city, interurban and vulnerable road user) and a multitude of others.
It also has 'Parking Assist Professional' and for young families there are ISOFIX child seat anchorages on the two outer rear seating positions and top-tethers for all three.
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 X5
BMW covers the X5 with a five year/unlimited km warranty and offers several service plans to suit different budgets and requirements.
For example, the 'Service Inclusive Basic' package covers all scheduled services over five years/80,000km for a total of $3450, or an average of $690 per year.
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.
