Summary
BMW X4
Look, personally I found it amusingly weird when German car companies started sloping the roofs on sedans and calling them “coupes”, despite the fact that they had four doors. Their ability to imagine segments, and find buyers in them, that have no reason to exist is almost something to admire.
But turning SUVs, like the already very capable X3, into coupes? Frankly, it’s like turning an ass into an elbow. Lower the roof to reduce headroom and shrink the boot? Why? Because it will look so sexy people won’t be able to resist it. That’s BMW’s approach with the X4 and, somehow, it seems to work.
And, to be fair, sporty SUVs are not a BMW thing: the Range Rover Evoque, Audi Q5 Sportback, and Mercedes-AMG’s range of GLC Coupé models have all taken off, each contributing toward an unlikely trend that doesn’t seem to be going away any time soon.

We’re having a steer of the 3.0 version to see what it’s like to have the somewhat bulky body of a mid-size SUV while shortchanging yourself on cabin space thanks to the lowered roof.

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 X47.5/10
Okay, so the BMW X4 xDrive30i is neither an ass nor an elbow, to be fair, it's more of a bulky shoulder muscle, or two.
I can't say I'll ever love the X4, the idea of it is a bit too weird for me, but I can't help admiring the way it looks and the way it drives.
It's a bit like a sedan on steroids - or an SUV on a diet, depending on your perspective - but that doesn’t take away from the fact that it’s fun to drive, comfortable and retains just enough coolness, and just enough practicality, to make it worthwhile.
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 X49/10
So here's the thing. Obviously I have a personal beef with the existence of vehicles like this, but my eyes cannot deny the facts - the X4 looks fantastic. It's muscular, imposing and smooth all at once. Unlike the X6, a bigger and less visually successful attempt to play the same styling tricks with an X5, it doesn't have a ridiculous rear view that looks like it shoulders and buttocks have been fused (although it's hard to miss just how small the rear window is).
Even more impressively, there's no denying it looks better than the X3 that gave birth to it, so I can easily see why someone in a BMW showroom could be drawn to it. At least until they sit inside.
If the exterior style and eye-catching Sophisto Grey metallic paint don’t make an immediate impression then your eyes will surely widen at the interior, resplendent with bold Tacora Red seats, Aluminium Rhombicle trim finisher and the kind of sleek, classy styling that BMW excels in.
Both the adjustable ambient lighting on the doors (we were partial to lilac) and door projectors that shot out what looked like robot wings onto the ground every time we hopped out of the X4 at night walked a fine line between futuristic cool and “parked out the front of a nightclub entrance” chintz, but over time the scales tipped more to the former.
The big differentiator between the X4 and X3, of course, is the sloped coupé roof, a design feature that may make the X4 look a little cooler, but at the expense of cabin space, but more of that in a moment.
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 X47/10
For a car that is very much a mid-sized SUV on the outside, the interior can feel a bit too snug, like you’re driving a compact car that’s tried on a suit a few sizes too big (for reference, I’m 175cm tall - above-average height drivers may find the snugness soon turns to claustrophobia).
While comfortable - it is BMW we’re talking about, after all - there’s not an overly abundant amount of headroom available, a feeling that becomes more pronounced should you shut the big moon roof.
My two children felt slightly too close to “you’re annoying me” distance from one another, which is to say this isn’t really the kind of car you should be getting if you plan on regularly ferrying about passengers in the rear who are bigger than a child. But I really don't think many people with kids would choose the X4 over the X3.
Boot space also takes a hit when compared to the X3 (550 litres versus 525-litres in the X4 - I was surprised the difference wasn't larger - although that expands to 1430-litres with the rear seats folded down.
The boot opening is also mouth-shaped, which makes packing in wide-load items more of an issue.
Cupholders are plentiful - two in the front, two in the rear, and bottle holders in each door - and there’s a decent-sized storage cubby in between the front two seats.
The sloped roof, and big fat A pillars, also result in the X4 being a bit more pinched at the rear, which is not especially great for visibility, with the vehicle’s blind spots taking some getting used to.
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 X47/10
Cost-wise, the X4 is roughly in the same ballpark as the other cars in this strange sub-segment, but when you add in optional extras - metallic paint, panorama glass sunroof and BMW Laserlight headlights among them - the base price of $95,900 plus on-road costs sneaks up to $101,800, which is is no small figure.
It’s also a considerable $8000 more than the SUV-shaped X3, meaning you’re essentially getting the same car, but with less cabin and boot space, for more money. To be fair, this is just part of a long tradition of the style-conscious buyer being willing to pay more for less, one that the invention of the coupe pretty much invented.
That kind of money also makes exclusions like adaptive cruise control, heated seats and wireless charging a bit of a head-scratcher.
Still, there’s plenty to love, including an M Sport kit that comes standard with the X4 (a suspension/brake package and various styling embellishments), butter-soft Tacora Red Vernasca leather seats (Sport adjustable for the driver and front passenger), 20-inch M light alloy double-spoked wheels, a head-up display, adaptive LED headlights, and an automatic tailgate.
There’s also a generous high-resolution 12.3-inch control display and digital 12.3-inch instrument display, the former operated by touch or via the rotary iDrive Touch Controller.
Cable-free Apple CarPlay and Android Auto are also available, but BMW allows you the option to use its iDrive system instead, just in case you're some kind of mad Munich fanboy - or you hate Apple.
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 X48/10
Now, prepare to be confused. In the past, the 3.0 in the xDrive3.0i nomenclature might have led you to believe you'd bought a BMW with a 3.0-litre straight six engine. But in this case, you have not, the 3.0 just means you have a more exciting version of the 2.0; a TwinPower turbo 2.0-litre inline four-cylinder engine, making 179kW and 353Nm that the xDrive system delivers to all four wheels.
The claimed zero to 100km/h time of 4.9 seconds feels completely realistic as this engine has plenty of poke. Put it in the Sport setting and you'll get some serious shove. Indeed, the switch between Comfort and Sport is very noticeable and changes the character of the car entirely.
The transmission is an eight-speed conventional torque converter automatic gearbox that’s both smooth and responsive.
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 X47/10
The X4’s 65-litre tank needs to be 95-octane at a minimum, and BMW’s claimed combined fuel consumption is 7.9 litres per 100km. The temptation to use its rorty little engine is going to push you higher, though - you chose the one with the 3.0 badge on it after all - and we averaged 10.9 litres per 100km in our week together, which was mainly city driving, to be fair.
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 X48/10
The impressive trick that BMW continually pulls off with its SUVs is giving them the same sensual, muscular steering as its sedans, and an impressively similar ride and handling balance.
The steering is the highlight here, but it's also noticeable how planted to the road it feels.
The X4 speaks to its looks, in fact, by feeling sportier and more alive to drive than you'd expect an X3 to be.
This is less an SUV for soccer mums and dads, and more a bastard love-child that’s into loud leather and bright neon - a CEO who dressed punk rock-lite on weekends, if you will.
If those weekends are bereft of child taxiing and loading up the boot with several tons of kid stuff, then you’ll have a blast in the X4.
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 X48/10
A 2018 test gave the X4 a five-star ANCAP safety rating, and an easily located button on the dash brings up the vehicle’s safety suite if you’re the kind of driver who likes to make a few adjustments.
A 360-degree camera offers multiple viewpoints and is a godsend when parking the X4, since the cabin makes the car feel smaller than it actually is on the outside, and the range of safety features on offer are more than adequate.
Those include autonomous emergency braking, dynamic braking lights, dynamic stability and traction control, rear-cross traffic alert, speed limit information and hill descent control.
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 X46/10
Despite all the brouhaha about other car manufacturers offering more generous warranty periods - seven years for Kia, for example - BMW has not shifted its stance, still offering its standard three-year unlimited-kilometre warranty. Frankly, it's just not good enough.
BMW also offer a Service Inclusive package for $2010 that covers owners for five years, or 80,000km.
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.
