Summary
Lexus RX
For those of us unlucky enough to remember the first Lexus RX to launch in Australia, the memories aren’t the fondest.
If you can’t remember it, just picture the stodgiest-looking SUV you can - make it so bland a mere picture of one could cure insomnia - dragging a glass-walled cube behind the rear wheels.
All of which makes the current-generation RX so incredible. I mean, just look at it; those big rims, the 3D-effect grille, the outrageous lines and creases. It’s about as far removed from its snooze-worthy predecessors as it is possible to get.
Little wonder, then, it has emerged as the second-strongest performer in the Lexus line-up. And with the RX recently refreshed (and with a seven-seat RX L model added for the first time) its high time we took a closer look at the Japanese premium brand’s large SUV.

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
Lexus RX7.9/10
A comfortable and ferociously well-equipped offering (even from the cheapest trim level) - and with a very good ownership package to boot - the RX has earned its place high in the Lexus pecking order.
There are faster, more pulse-quickening SUVs available, of course, but as a sedate suburban warrior, the RX is hard to fault. For ours, we'd be opting for the bang-for-bucks sweet spot of the Luxury trim, paired with the punchy-but-efficient hybrid powertrain.
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
Lexus RX
This current RX is like the butterfly that’s emerged from the caterpillar-cocoon of the older models, looking plenty premium and serving up road presence by the bagful.
No matter which model you go for, you’ll find the angry 'Spindle Grille' up front (which, for ours, is reminiscent of the Predator’s toothy grin, while 20-inch alloys are an impressive size, and a very un-Lexus body kit wraps from the front end all the way around to the rear spoiler.
The interior (check out the interior photos for a closer look) is premium-feeling, if a little busy, with the doors and dash covered in a combination of soft-touch materials and padded leather.
The brushed aluminium-look central tunnel that separates the front seats is super wide, as it houses the cupholders, drive-mode selector and the strange mousepad that controls the entertainment system, but feels nice under the touch and becomes a kind of focal point in the cabin.
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
Lexus RX
With dimensions stretching 4890mm long and 1895mm wide, the RX sits squarely in the large SUV category, and there’s plenty of space for riders in both the first and second row.
Up front, there is a cup holder for both driver and passenger and extendable pockets in each of the front doors, and the deep cubby that separates the front seats adds plenty of storage space, and is home to two USB connections, a power outlet and and aux connection, but there is no sunglass holder.
The interior dimensions ensure there’s plenty of space in the back seat, although the central stack that houses the air vents and another power outlet does jut out into the rear legroom of the middle-seat passenger. There are two bonus cupholders hidden in a pulldown divider that drops from the middle seat, and two ISOFIX attachment points along the backseat.
Open the automatic tailgate (by waving your hand in front of the Lexus badge) and you’ll find 453 litres of luggage capacity, with boot space increasing to 942 litres by folding the backseat down. Theres’s a sliding cargo cover (the SUV version of a tonneau cover), too.
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
Lexus RX
The Lexus RX arrives in plenty of trim and engine combinations, so exactly how much yours will cost is largely up to you.
The minimum RRP, though, is $74,251, which will buy you an RX300 Luxury. A little further up the price list lives the RX350 Luxury, at $81,421, which makes use of a bigger engine, while the hybrid RX450h Luxury will set you back $90,160.
The range then steps up to the second of three trim levels, the F Sport, for which you’ll be paying $86,551 for the RX300, $93,721 for the RX350 and $102,460 for the RX450h.
Finally, the range tops out with the Sport Luxury trim, which will push the budget to $92,701 for the RX300, $99,871 for the RX350 and $108,610 for the RX450h.
Okay, so that’s what you’ll be paying. But take a deep breath now, we’re dive into the model comparison.
Even the Luxury-badged cars are a premium package, arriving with 20-inch alloy wheels, tinted windows, a powered tailgate, LED headlights and fog lights (with daytime running lights) , a smart key with keyless entry, roof rails and rain-sensing wipers. Inside, expect a laundry list of standard features, including dual-zone climate control, sat nav (which, as far as GPS navigation systems go, is a breeze to operate), push-button start and leather trim.
Your 8.0-inch screen (it’s not a touch screen) pairs with digital radio and 12 speakers, there’s Bluetooth for your MP3s, as well as wireless charging (though iPhones require a special case), and you get heated and cooled front seats, too. Be warned; there is no Apple CarPlay or Android Auto anywhere in the range.
Step up to the F Sport - a pseudo sport edition - and you’ll add a bigger, 12.3-inch infotainment screen that adds a CD player and DVD player and pairs with a better Mark Levinson sound system complete with 15 speakers (including a subwoofer). You get a new colour head-up display (HUD), too, and a whole heap of sport-flavoured styling flourishes.
Compare that to the Sport Luxury, which adds with soft leather trim elements, heated seats in the second row (vs just the front seats on the F Sport trim) and a power folding function for the backseat. There’s no heated steering wheel here, but then, who needs one in Australia? The adaptive front lighting system cn be switched off, too, should you prefer the traditional approach.
Colours include 'Titanium' (metallic grey), 'Sonic Quartz' (white), 'Premium Silver', 'Onyx' (a kind of black), 'Graphite Black', 'Vermilion' (red), 'Metallic Silk' (rose gold), 'Deep Metallic Bronze' (a fancy brown) and 'Deep Blue'.
How many seats? That would be five. If you want a third row seat, then you’re shopping for the RX L, as the standard RX is strictly a five-seat affair.
A thick accessories catalogue includes specialty floor mats, roof rack and boot liner options, bull bar, nudge bar and rear seat entertainment system options, as well as a panoramic sunroof, which will set you back $3675. You won't find Homelink though (which automatically opens your garage door), as it's yet to be made available in Australia.
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
Lexus RX
There are three (petrol) engine size options on offer; a turbocharged 2.0-litre in the RX300, a punchy V6 in the RX350 and a hybrid set-up in the RX450.
First up, the four-cylinder turbo engine serves up 175kW/350Nm (decent specs for a smaller engine), channelling it through a six-speed automatic gearbox and sending it on to the front wheels.
The six-cylinder petrol engine is good for 221kW/370Nm, sending that power to all four wheels via an eight-speed automatic transmission.
The hybrid (it’s not a plug-in hybrid) option uses the exact same engine, but paired with an electric motor that lifts the total output to 230kW/335Nm. That combination pairs with a CVT auto, sending its horsepower to all four wheels.
All are petrol powered (there are no diesel or LPG options, and no manual transmission, for that matter), and for ours, the combined engine specs of the hybrid powertrain make the most - and most expensive - sense.
While the Luxury, F-Sport and Sport Luxury models all have adjustable drive modes (including Eco mode), tweaking throttle response and gearing, only the Sport Luxury serves up true variable suspension.
The F Sport and Sport Luxury also make use of the Lexus AWD system (though 4WD aficionados will notice the lack of low range that prevents it being a true 4x4). The RX300 is front-wheel drive, with no rear-wheel drive options anywhere in the range.
Expect a braked towing capacity of at least 1000kg (provided you’ve picked a tow bar/tow hitch receiver from the accessories catalogue) with a gross vehicle weight that starts from 2500kg.
For reported problems and maintenance, including transmission problems, battery and oil type, and changing your timing belt or chain, see our owner’s page.
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
Lexus RX
For the smaller, turbocharged engine, Lexus claims fuel economy of 8.1 litres per 100km on the combined cycle, with emissions pegged at 189g/km of CO2. Stepping up to the RX350 increases fuel consumption numbers to 9.6L/100km and 223g/km, while the hybrid gets by with impressive mileage of just 5.7L/100km and 131g/km.
Expect a 72-litre fuel tank that requires 95RON fuel in the 300 and 350, while the hybrid’s fuel tank capacity is 65 litres.
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
Lexus RX
If BMW serves up the 'ultimate driving machine' and Mercedes delivers 'the best or nothing', then surely the review tag line for the RX SUV range should be 'easy like a Sunday morning'.
Sure, there are sportier-feeling SUVs - and faster ones, too - but there is an easy comfort to the way the RX goes about its business that you’ll undoubtedly appreciate more frequently than you would harder suspension, more in-touch steering and the endless pursuit of speed and 0-100 performance figures.
For the record, though, the hybrid cars will sprint from 0-100km/h in a brisk 7.7sec, a smidge quicker than the 8.0sec of the regular V6. The RX300 records a far more leisurely 9.2sec.
Probably most impressive, the RX doesn't feel overly large and cumbersome, and nor does its turning radius, and it’s equally at home in the cramped inner city as it is eating up kays on the freeway. The six- or eight-speed transmission is silky-smooth seamless, switching between cogs without you even noticing, and the cabin is commendably quiet - especially when you're coasting though the ‘burbs - locking the worst road noise outside out of the cabin.
You can inject a little excitement by selecting 'Sport' or 'Sport +' via the central dial, tweaking the accelerator and steering settings, and in Sport Luxury cars, firming up the suspension, removing some of the lolling about in corners, though there’s no air suspension.
While the F-Sport and Sport Luxury cars are AWD-equipped, the off road capability is hampered somewhat by its ground clearance, big chrome-look wheels and skirtings. This is an SUV built for the city over the bush, but you likely don’t need us to tell you that.
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
Lexus RX
Even the cheapest RX (which, admittedly, isn’t all that cheap) arrives with a long list of standard safety features, including a reversing camera, blind spot monitor with rear cross-traffic alert, AEB, lane assist and parking sensors (but no park assist).
You’ll also find 10 airbags, and twin ISOFIX mountings for you baby car seat, as well as cruise control and the usual suite of braking and traction control systems.
The Lexus RX received a five-star ANCAP safety rating, the best possible ratings outcome, when tested in 2015. The Lexus RX is built in Japan.
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
Lexus RX
Expect a four-year/100,000km warranty (that's 12 months longer than BMW or Mercedes-Benz, so think of it as a kind of extended warranty), and the RX will require a trip to the service centre every 12 months or 15,000km.
Your first service cost is gratis, and the total maintenance cost for each service is available online - so there are no surprises at the dealership.
For common problems, complaints, issues and the like, visit our Lexus RX owner’s page. But your owner’s manual should be required reading, too. Traditionally, Lexus product ranks well in reliability ratings, resale value and initial value rating charts.
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.
