Lexus RX VS BMW X6
- Bonkers performance
- High-end interior
- (Somewhat) affordable pricetag
- Questionable rear styling
- Limited rear-seat headroom
- Firm suspension
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.

|Fuel Type||Premium Unleaded Petrol|
The BMW X6 has long been the ugly duckling of the Bavarian brand’s SUV family, often cited as the genesis of the swoopy, coupe crossover trend.
But look back at its 12-year history, and it's clear that the X6 has resonated with buyers around the world with more than 400,000 units produced.
Now in its third-generation form, the X6 has shed the awkward and even sometimes dorky image of its progenitor and evolved into a much more mature and confident model.
Crowing the new line-up, however, is the flagship M Competition grade that shoehorns a sporty V8 petrol engine to match the bulky and brawny exterior.
Is this a recipe for success, or should BMW go back to the drawing board?
|Engine Type||4.4L turbo|
|Fuel Type||Premium Unleaded Petrol|
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.
SUVs are so hot right now, and BMW’s X6 M Competition is the hottest high-riding coupe you can get until its German rivals bring in their high-powered equivalents.
In a lot of ways, the X6 M Competition is one of the most BMW-iest models available today; it's covered head to toe in luxurious features, its performance puts most sports cars to shame and it oozes a don’t-care-what-you-think swagger.
What more could you want from a modern BMW? Maybe high safety standards and a practical interior space? The X6 M Competition has those too.
Sure, you could go for the slightly cheaper and more conventionally styled X5 M Competition, but if you are spending more than $200,000 on a performance SUV, don’t you want to stand out from the crowd? And stand out the X6 M Competition certainly does.
Note: CarsGuide attended this event as a guest of the manufacturer, with travel and meals provided.
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.
The X6 has long been a love-it-or-hate-it model for BMW, and in it’s latest third-generation form, the styling is as polarising as ever.
Maybe it’s the fact that more coupe-like SUVs have hit the market since the original X6's debut, or that we’ve had time to get used to the idea, but the latest X6 looks … good?
OK, we’re as surprised as anyone, but, especially in this top-spec M Competition form, the athletic proportions, heavily sloped roofline and chunky bodywork don’t look all that awkward or unattractive.
What also helps set the X6 M Competition apart, is its sports body kit, fender vents, aerodynamically optimised side mirrors, arch-filling wheels and black highlights befitting the performance-honed flagship variant.
It certainly stands out from the usual SUV crowd and, with a volcano of an engine tucked underneath the sculpted bonnet, the X6 M Competition is not a case of all show and no go.
You could argue that the X6 M Competition’s exterior styling is a bit ostentatious and over the top, but what would you expect a large, luxury, performance SUV to look like?
Step inside the cabin and the interior balances the sporty and luxury elements almost perfectly.
The front sports seats are clad in soft Marino leather with hexagonal quilting, carbon-fibre detailing is peppered throughout the dashboard and centre console, and small touches, such as the red start button and M toggles, elevate the X6 M competition from its more standard siblings.
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.
Measuring 4941mm long, 2019mm wide, 1692mm tall and with a 2972mm wheelbase, the X6 M Competition offers plenty of interior space occupants.
There is front-seat space aplenty for passengers, despite sports seats that hug and support in all the right places, while the rear seats are also surprisingly functional.
Even with my six-foot-tall frame positioned behind the driver’s seat set for my height, I still comfortably fit and had enough leg- and shoulder-room.
The sloping roofline however, doesn’t help the headroom situation with my head just grazing the Alcantara headliner.
It’s a different story for the middle seat though, which will only fit children due to the raised floor and seating positioning.
All in all, I'm actually surprised at how usable the rear-seat room is in the X6 M Competition – it's definitely more practical than the stylish exterior would suggest.
Storage options abound throughout the cabin as well, with a huge storage bin found in each door that is easily able to accommodate large drink bottles.
The central storage bin is also deep and cavernous, but it can be a bit difficult to retrieve your phone from the wireless phone charger there as it's tucked away under the shutter.
The 580-litre boot can expand to 1539L with the rear seats folded.
While that figure doesn’t quite match the 650L/1870L figure of its X5 twin, it's still more than enough space to take care of the weekly shopping and family stroller.
Price and features
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.
The BMW X6 Competition wears a $213,900 before on-road costs pricetag, just $4000 more expensive than its more conventionally styled X5 twin.
While a $200,000-plus pricetag is certainly not chump change, things start to look a bit better when stacking up the X6 M Competition against other models that share the same engine and platform.
Also, consider that the X6 is an SUV, making it more appealing to those looking for a higher ride height and more practical storage options.
As standard, the X6 M Compettition is fitted with four-zone climate control, soft-close doors, automatic tailgate, electric front seat adjustment, heated front seats, Harman Kardon sound system, panoramic glass sunroof, adjustable exhaust, keyless entry and push-button start.
For the instrument panel, BMW has fitted its 12.3-inch screen, while the multimedia system is a 12.3-inch touchscreen unit with support for Apple CarPlay, gesture controls, digital radio and wireless smartphone charging.
However, it’s the attention to detail that we appreciate in a luxury SUV like this.
Take, for example, the spare tyre, which is stored under the floor of the boot. In any other car where this happens, you would just have to lift up the floor and then struggle to take the tyre out as you fight to prop up the floor. Not in the X6 – the floor panel has a gas strut to keep it from dropping when it's lifted. Clever!
The front cupholders are also fitted with heating and cooling functionality, both of which have two settings.
Befitting an M model, the X6 M Competition also scores an active differential, sports exhaust, adaptive suspension, uprated brakes to go with its potent engine.
Of note, there is no cooling option for the seats and the steering wheel misses out on a heating element.
However, the metallic paintwork and carbon-fibre interior flourishes as seen on our test car are no-cost options.
Engine & trans
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.
Drive is sent to the road via a rear-biased xDrive all-wheel-drive system, which enables a zero-to-100km/h acceleration time of 3.8 seconds. The X6 tips the scales at 2295kg, so this level of acceleration almost defies the laws of physics.
The engine is shared with the X5 M Competition, M5 Competition and M8 Competition.
The X6 M Competition also outpowers its Mercedes-AMG GLE 63 S Coupe rival by 30kW, though the Affalaterbach SUV produces 10Nm more torque.
However, it is important to note that the current Mercedes uses the older 5.5-litre twin-turbo V8 engine, and is due to be replaced with a new GLE 63 S model that switches to AMG’s ubiquitous 4.0-litre twin-turbo V8 for 450kW/850Nm.
Audi’s RS Q8 is also incoming later this year, and packs a 441kW/800Nm punch thanks to a 4.0-litre twin-turbo petrol V8.
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.
Official fuel consumption figures in the X6 M Competition are pegged at 12.5 litres per 100km, however, we managed 14.6L/100km in a morning drive covering almost 200km.
No doubt the hefty weight and big petrol V8 engine contribute to the higher fuel bill, but the start/stop engine technology helps keep the figure down.
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.
With such a large footprint, you just don’t expect the X6 M Competition to drive as well as it does, but it’s great to have your expectations checked every now and again.
The seating position is spot-on thanks to heaps of adjustability in the driver’s chair and the steering wheel, while visibility (even out the small rear window) is excellent.
All the controls fall easily in hand, and if you just left the X6 to its own devices, the sporty elements almost fade away into the background.
Dive into the drive settings, however, and you will notice Sport and Sport Plus options for the engine and chassis, while the steering, brake and M xDrive settings can also be dialled up a notch.
There isn’t a ‘set-and-forget’ drive mode switch though, as each of the aforementioned elements can be adjusted individually to dial in the exact response you want from the car.
Even the transmission has its own independent setting, with shifts in manual or automatic mode able to be tweaked to three levels of intensity each, while the exhaust also has an option for loud or less loud.
We love the flexibility this affords, and opens up the possibility of having the engine on full attack mode while the suspension and transmission are on the comfort settings, but it does require some time sitting in the driver’s seat and tweaking this and that to get things right.
Once you work it out though, you can store these settings in M1 or M2 modes, which can be switched on with the push of a button on the steering wheel.
With everything switched to the sportiest options, the X6 M Competition is much more akin to a rapid hot hatch attacking corners and devouring the open road than its high-riding SUV body style would suggest.
Credit where it’s due, BMW’s M boffins know a thing or two about building a big barnstorming bruiser.
Fitted with gigantic 315/30 rear and 295/35 front Michelin Pilot Sport 4S tyres, the X6 M Competition benefits from superglue-like levels of grip in most situations, but a stab of throttle can still overwhelm the rear axle mid-corner.
Pulling up is a non-issue in the two-tonne-plus SUV, thanks to M Compound Brakes with six-piston fronts grabbing 395mm discs, and single-piston rears biting 380mm discs.
When you're not putting the boot in, the X6 M Competition also doubles as a convincing luxury runabout, but even in the chassis’ most comfort-orientated setting, road imperfections and high-speed bumps transmit directly through to the occupants.
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.
The BMW X6 has not been tested by ANCAP or Euro NCAP and does not have a crash rating.
However, the mechanically related X5 large SUV scored a maximum five stars when tested in 2018, notching 89 and 87 per cent for the adult- and child-occupant protection tests respectively.
Safety equipment fitted to the X6 M Competition includes a surround-view monitor, tyre pressure and temperature monitor, autonomous emergency braking (AEB), adaptive cruise control, lane-keep assist, lane-departure warning, reversion camera, rear cross-traffic alert, front and rear parking sensors, and built-in dash cam.
In terms of safety gear, there really isn’t much left on the table for the X6 M Competition to pack in, though it does lose a point for not having a crash-safety rating.
In its favour though is the fact its onboard technology works unobtrusively and the adaptive cruise control is one of the smoothest and easy-to-use systems I've experienced.
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.
Scheduled service intervals are pegged at every 12 months or 15,000km, whichever comes first.
BMW offers two five-year/80,000km service plans with the X6 M Competition, a basic option for $4134 and a Plus for $11,188, with the later including the replacement of brake pads, clutch and wiper blades.
Though pricey to maintain, it’s not unexpected for a vehicle at this price point.
What we like to see though, is BMW match Mercedes’ pledge for a five-year warranty across its range, including high-performance AMG models.
