BMW X5 VS Bentley Bentayga
- Aggressive styling
- Genuine practicality
- Ferocious performance
- Half-baked exhaust system
- Far from fuel-efficient
- Substandard warranty
- Magnificent twin-turbo petrol V8
- Superbly comfortable
- Surprisingly dynamic for its size
- A little awkward looking
- Low on standard advanced safety equipment
- Boot is smaller compared to rivals
Way back in 2009, the X5 was the first SUV to get the go-fast treatment from BMW’s high-performance M division. At the time, it was a crazy thought, but in 2020, it’s easy to see why Munich went down the (then) road less travelled.
But just exactly how good is the X5 M Competition? We had the unenviable task of putting it to test to find out.
|Engine Type||4.4L turbo|
|Fuel Type||Premium Unleaded Petrol|
When Bentley revealed its Bentayga in 2015 the British brand called it “the fastest, most powerful, most luxurious, and most exclusive SUV in the world."
See, that first Bentayga packed a W12 engine, but the SUV we have here was introduced in 2018 with a twin-turbo petrol V8 and a reduced price tag.
So how does this more affordable and less powerful Bentayga stack up to Bentley's lofty ambitions?
Well you’ve come to the right place, because along with speed, power, luxury and exclusivity I can also talk about the Bentayga V8’s other attributes, such as what it’s like to park, drop children off at school in, do the shopping in and even go through a 'drive thru' in.
Yes, the Bentley Bentayga V8 came to live with my family for a week and as with any house guest you quickly find out what’s great about them… and then there are those times you walk in on them not looking their best.

After spending a day with the BMW X5 M Competition, we can’t help but wonder if it’s the ultimate vehicle for families.
On one hand, it nails the practicality brief and is loaded with standard equipment, including the key advanced driver-assist systems. On the other, its performance in a straight line and around corners is otherworldly. Oh, and it looks sporty and feels luxurious, too.
That said, we could absolutely live with the high fuel bill if this was our daily driver, but there’s only one problem: does anyone have a spare $250,000?
Is the new BMW X5 M Competition the ultimate family vehicle? Tell us what you think in the comments below.
Note: CarsGuide attended this event as a guest of the manufacturer, with travel and meals provided.
The Bentayga is Bentley’s first attempt at an SUV and the Bentayga V8 is a more recent addition to the line-up that provides an alternative to the W12, hybrid and diesel models.
There’s no doubt the Bentayga V8 delivers an exceptionally good driving experience from its power and athleticism to the serene cabin and comfortable ride.
Where the Bentley Bentayga V8 appears to be lacking is in cabin technology which compared to other luxury SUVs is becoming outdated, and in standard advanced safety equipment. We’d expect this to be addressed in future revisions of the SUV.
Does the Bentayga fit the ultra-luxury SUV bill? Tell us what you think in the comments section below.
In our humble opinion, the X5 is one of the best-looking SUVs on the market today, so it’s no surprise the X5 M Competition is a knockout in its own right.
Up front, it cuts an imposing figure thanks to its version of BMW’s signature kidney grille, which has a double-slat insert and is finished in gloss-black like most of the exterior trim.
That said, it’s the front bumper that sucks you in with its large air dam and side air intakes, all of which have honeycomb inserts.
Even Laserlight headlights add a touch of menace thanks to their integrated dual-hockey-stick LED daytime running lights, which look plain angry.
Around the side, the X5 M Competition is a little more restrained, with the 21- (front) and 22-inch (rear) alloy wheels the obvious giveaway, while the more aggressive side mirrors and air breathers are a lesson in subtlety.
At the rear, the visual aggro is most apparent thanks to the sculpted bumper, which incorporates a chunky diffuser that plays host to the bi-modal exhaust system’s black chrome 100mm tailpipes. Utterly delicious, we say.
Inside, BMW M has put its best foot forward to make the X5 M Competition feel that little bit more special than the X5.
The eyes are immediately drawn to the multifunction front sports seats, which manage to be super supportive and super comfortable at the same time.
Like the middle and lower dashboard, door inserts, armrests, knee rests and door bins, they’re covered in supple Merino leather (Silverstone grey and black in our test vehicle), which even has honeycomb insert stitching in some sections.
Black Walknappa leather trims the upper dashboard, door shoulders, steering wheel and gear selector, with the latter two unique to the X5 M Competition, alongside the red start-stop button and M-specific seat belts, scuff plates and floor mats.
A black Alcantara headliner adds some more luxury to the equation, while our test vehicle’s gloss carbon-fibre trim ensures there’s some sport in it, too.
Technology-wise, there’s the 12.3-inch touchscreen, which is powered by the now-familiar BMW Operating System 7.0, although this version gets M-specific content. That said, it still has gesture and always-on voice control, but both fall short of the rotary dial’s greatness.
The 12.3-inch digital instrument cluster and windshield-projected head-up display get the biggest M makeovers, though, with the new M Mode giving them a focused theme (and turning off the advanced driver-assist system) for spirited driving.
The Bentayga is unmistakably a Bentley, but I have my doubts whether this first attempt by the British brand to build an SUV has been a design success.
To me, the rear three-quarter view is its best angle with those trademark rear haunches, but front-on reveals an overbite I can’t ‘unsee’.
But then again perhaps I’m the one with bad taste, I mean I think Lamborghini's Urus SUV, which uses the same MLB Evo platform, is a work of art in its design, staying faithful to the sports cars in the family, while acquiring a brave look of its own.
I also found the interior of the Bentayga V8 disappointing. Not in terms of overall craftsmanship but rather its outdated technology and plain styling.
The 8.0-inch screen is almost identical to the one used in the Volkswagen Golf in 2016. But the Golf received its Mk 7.5 update in 2017 and with it a stunning touchscreen which hasn't made it into the Bentayga yet.
The steering wheel, too, has identical switchgear to the $42K Audi A3 I reviewed two weeks ago and you can add the indicator and wiper stalks into that mix as well.
While the fit and finish of the upholstery was outstanding, there was a lack of interior refinement in some places. For example, the cupholders, had rough and sharp plastic edges, the gear shifter was also plastic and felt flimsy, while the fold-down armrest in the back seats also lacked refinement in the way it was constructed and lowered without damping.
At just over 5.1m long, 2.2m wide (including the wing mirrors) and a little over 1.7m tall the Bentayga is big but it’s the same length and width as the Urus, and a bit taller. The Bentayga’s wheelbase is only 7.0mm shorter than the Urus’s at 2995mm.
The Bentayga isn’t the longest of the Bentleys, that’s for sure. The Mulsanne is 5.6m end-to- end and the Flying Spur is 5.3m in length. So, the Bentayga V8 is almost ‘fun-size’ in Bentley terms, even though it’s large.
The Bentayga is made in the United Kingdom at Bentley’s home (since 1946) in Crewe.
Measuring 4938mm long, 2015mm wide and 1747mm tall, the X5 M Competition is well and truly a large SUV, and that means good things for its practicality.
Cargo capacity is generous, at 650L, but can be increased to a truly massive 1870L with the 40/60 split-fold rear bench stowed – an action that can be done via the boot’s manual-release latches.
The boot has six tie-down points for securing loads, as well as two bag hooks and two side storage nets. There’s also a 12V power outlet, but the best part is the power-operated parcel shelf, which stows itself underfloor when not in use. Awesome!
There are plenty of genuine in-cabin storage options, too, with both the glovebox and central bin of the large variety, while the front door bins can carry an astounding four regular bottles. The rear door bins can fit three apiece.
The two cupholders at the front of the centre console actually have heating and cooling, which is pretty hot/cool (bad pun intended).
The second row’s fold-down armrest has a pair of basic cupholder as well as a shallow tray, which joins the small driver-side cubby as the two most random storage spaces on hand, while map pockets are attached to front seat backrests.
Given the size on offer, it’s no surprise the second row is nice place to sit in. Behind my 184cm driving position, more than four inches of legroom is on offer, while headroom is also generous, at two inches, despite the standard fitment of a panoramic sunroof.
Better yet, the transmission tunnel is quite short, meaning there’s plenty of footwell to go around, which will come in handy given the rear bench can accommodate three adults abreast with relative ease.
Child seats are also a cinch thanks to the outboard seats’ top-tether and ISOFIX anchorage points – and the generous aperture of the rear doors.
Connectivity-wise, there’s a wireless smartphone charger, a USB-A port and a 12V power outlet ahead of the aforementioned front cupholders, while a USB-C port is found in the central bin.
Rear occupants only get access to a 12V power outlet, which is below their central air vents. Yep, the kids won’t be happy with the lack of USB ports to recharge their devices with.
The Bentayga V8 may be an SUV, but that doesn’t immediately make it a god of practicality. While roomy up front for the driver and co-pilot, the rear seating is not exactly limo-like, although at 191cm tall I can sit with about 100mm of space. Headroom is slightly limited by the edges of the panoramic sunroof for rear riders, too.
Storage in the cabin is adequate with two cupholders and small door pockets in the back, and another two cupholders and larger door pockets in the front. There’s also a shallow centre console storage bin and two wells for loose items in front of it.
The Bentayga V8’s boot with the rear seats in place has a cargo capacity of 484 litres – that’s measured to the cargo cover, but to the roof its 589 litres.
That boot space is still smaller than the Lamborghini Urus’s 616 litres and there’s much less boot space than the Audi Q7 and Cayenne which both have 770 litres measured to the roof, too.
Making life easier is the load-height lowering system which is operated with a button located in the boot.
The tailgate is powered, but the kick-open function (standard on say an Audi Q5) is an option you’ll have to pay for on the Bentayga.
As for power outlets and charging, the Bentayga’s falling out-of-date here, too. There is no wireless charger for phones, but there are two USB ports up front and three 12-volt outlets (one in the front and two in the rear row) on-board.
Price and features
Priced from $209,900 plus on-road costs, the new X5 M Competition is $21,171 dearer than its non-Competition predecessor and commands a $58,000 premium over the M50i, although buyers are compensated for the extra spend.
Standard equipment not already mentioned includes dusk-sensing lights, rain-sensing wipers, auto-folding side mirrors with heating, soft-close doors, roof rails, a hands-free power-operated split tailgate and LED tail-lights.
Inside, satellite navigation with live traffic, wireless Apple CarPlay support, DAB+ digital radio, a 16-speaker Harman/Kardon surround-sound system, keyless entry and start, power-adjustable front seats with heating, a power-adjustable steering column, four-zone climate control, an auto-dimming rearview mirror and ambient lighting feature.
Our test vehicle is finished in stunning Marina Bay Blue metallic paintwork, which is one of several no-cost options.
Speaking of which, the options list is surprisingly short, but a highlight is the $7500 Indulgence Package, which bundles in some features that should be standard at this price point, such as cooled front seats, a heated steering and heated rear seats.
The X5 M Competition’s main rivals are the wagon versions of the yet-to-be-released second-generation Mercedes-AMG GLE63 S and Porsche Cayenne Turbo ($241,600), which has been kicking around for a couple of years now.
That’s the question those who can’t afford a Bentley Bentayga V8 want to know the answer to, and the one that those who can don’t ask.
I’m in the first group, so I can tell you the Bentley Bentayga V8 has a list price of $334,700. Our car had $87,412 in options which we’ll take a look at, but all up including the on-road costs, our test car had a price of $454,918.
Standard features inside include leather upholstery in a choice of five colours, 'Dark Fiddleback Eucalyptus' veneer trim, a three-spoke leather clad steering wheel, ‘B’ foot pedals, Bentley embossed treadplates, an 8.0-inch touchscreen with Apple CarPlay and Android Auto, sat nav, a 10-speaker stereo, CD player, digital radio, four-zone climate control and shifting paddles.
Exterior standard features include 21-inch wheels, black painted brake calipers, air suspension with four height settings, a choice of seven paint colours, gloss black radiator grille, black lower bumper grille, LED headlights and LED tail-lights, twin quad-exhaust and a panoramic sun roof.
Our car was fitted with options galore which is common in vehicles loaned to the media. Car companies often use these cars to showcase available options rather than represent a typical customer specification.
There’s the 'Artica White' paint from the bespoke Mulliner range costing $14,536; 'our' car's 22-inch wheels weigh in at $9999, as do the fixed side steps; the tow bar and brake controller (with Audi Q7 badging, see the images) is $6989; body coloured lower bodywork is $2781 and LED puddle lights are $2116.
Then there’s the acoustic glazing for $2667, front seats with the 'Comfort Specification' for $7422 and then $8080 for the 'Hot Spur' main hide and 'Beluga' secondary hide leather upholstery, the $3825 piano black veneer trim and if you want the Bentley logo embroidered into the headrests (as per our car) it costs $1387.
Does it represent good value for the price? Not by regular standards, but Bentleys are anything but regular cars, and those that buy them tend not to look at prices.
But, as I do with every car I review (whether it costs $30,000 or $300,000), I ask the manufacturer for a list of options fitted to the test car and the as-tested pricing, and I always include those options and their costs in my review.
Engine & trans
The X5 M Competition is motivated by a monstrous 4.4-litre twin-turbo V8 petrol engine, which punches out a formidable 460kW of power at 6000rpm and 750Nm of torque from 1800-5800rpm, with the former up 37kW, while the latter is unchanged.
Once again, a near-perfect eight-speed torque-converter automatic transmission (with paddle-shifters) is responsible for swapping gears here.
This combination helps the X5 M Competition sprint from a standstill to 100km/h in a supercar-scaring 3.8 seconds. And, no, that is not a typo.
The scores I’ve awarded to the Bentayga V8 so far haven’t been impressive, but now we come to the twin-turbo 4.0-litre V8.
Derived from the same unit found in the Audi RS6 this turbo-petrol V8 makes 404kW/770Nm. That’s enough grunt to get this 2.4 tonne beast from parked in your garage to 100km/h in 4.5 seconds, provided your driveway is at least 163.04m long, which for some owners would be entirely possible.
That’s not as quick as the Urus which can do it in 3.6 seconds, but while the Lamborghini shares the same engine it’s tuned to make 478kW/850Nm and that SUV is about 200 kilos lighter.
Shifting gears wonderfully in the Bentayga V8 is an eight-speed automatic which suits the Bentley better with its seamless but not-in-a-huge-hurry gear swaps than the same unit in the Urus.
While there are those who think a W12, as found in the first Bentayga, is more in line with Bentley’s ethos, I think this V8 is superb in its power delivery and sounds subtle but magnificent.
The braked towing capacity of the Bentley Bentayga is 3500kg.
The X5 M Competition’s fuel consumption on the combined-cycle test (ADR 81/02) is 12.5 litres per kilometre, while its claimed carbon dioxide (CO2) emissions are 286 grams per kilometre. Both are a little keen considering the level of performance on offer.
In reality, though, the X5 M Competition really likes a drink – a very large drink. We averaged 18.2L/100km over 330km of driving, which predominately took place on country roads, while the rest was an even split between highways city and traffic.
Yes, there was plenty of spirited driving, so a more balanced real-world figure would be lower – but not by much. Indeed, this is a vehicle you buy if you don’t care how much it costs to fill up.
Speaking of which, the X5 M Competition’s 86L fuel tank takes 95RON petrol at minimum.
A 4.0-litre twin-turbo petrol V8 pushing a 2.4-tonne SUV loaded up with people and possibly towing a horse float is going to want to be fed fuel – lots of fuel.
And that’s even if engine has cylinder deactivation like the one in the Bentayga V8 which can cut out four of the eight when not under load.
Officially, combined fuel consumption for the Bentayga V8 is 11.4L/100km, but after 112km of fuel testing on a combination of motorways, suburban and city roads I measured 21.1L/100km at the petrol pump.
I’m not surprised. For most of that I was in Sport mode or in the traffic, or in both at the same time.
Surprise, surprise: the X5 M Competition is an absolute hoot in a straight line – and around corners.
The level of performance on tap is unhinged, with the 4.4-litre twin-turbo V8 serving up body shot after body shot.
Off the line, the X5 M Competition hunkers down and then delivers its 750Nm just above idle (1800rpm), holding it all the way to 5800rpm. That’s a staggeringly wide torque band, one that ensures it will relentlessly pull in any gear.
And just as the torque curve springs back into action, peak power arrives at 6000rpm and reminds you that you’re dealing with 460kW underfoot. Make no mistake, this is a truly epic engine.
A lot of the credit has to go to the eight-speed torque-converter automatic, though, as it is almost flawless. We particularly like its responsiveness – it literally kicks down a ratio or two before you think you’ve pushed the accelerator pedal hard enough.
That said, it often has a hard time recognising when the fun is over, holding onto lower gears for longer than required before eventually upshifting.
And while it’s smooth, it is still quick in operation. Just like the throttle, the transmission has three settings, which progressively up the ante. For the latter, the softest setting is too soft, while the medium setting is just right, and the hardest setting is best left for the track.
Needless to say, we adore this combination, but one word of warning: the bi-modal sports exhaust system doesn’t serve up enough aural pleasure. There’s no mistaking this for anything but a booming V8 soundtrack, but characterful crackles and pops are absent.
Now, put your hand up if you assume every M model has a bone-crunching ride… Yes, us too… But the X5 M Competition is surprisingly the exception to the rule.
It comes with Adaptive M Suspension Professional, which consists of double-wishbone front and five-link rear axles with adaptive dampers, which mean there’s bandwidth to play with, although BMW M usually targets sportiness over comfort, even for their softest setting.
Not this time, though, as the X5 M Competition rides a lot better than expected, no matter the setting. Simply put, it’s compliant when other M models are not.
Does this mean it deals with all road imperfections with aplomb? Of course not, but it’s more than liveable. Potholes aren’t nice (but when are they?), and its firmer tune makes speed bumps more challenging to deal with as a passenger, but they’re not deal-breakers.
Despite the apparent focus on in-cabin comfort, the X5 M Competition is still an absolute beast through the bends.
When you’ve got a 2310kg kerb weight, physics are well and truly working against you, but BMW M evidently said, ‘To hell with the science’.
The results are mind-boggling. The X5 M Competition has no right being this agile. In the twisty stuff, it feels like a much smaller car to drive.
Yes, there’s still body roll to contend with in the corners, but most of it is cancelled out by the stunning active anti-roll bars, which do their best to keep things balanced. Handling is also improved by the chassis’ increased torsional stiffness.
Of course, the X5 M Competition’s electric power steering also deserves a shout-out here. It’s super direct, so much so that it’s almost twitchy, but we really love how sporty it feels. Feedback through the wheel is also excellent, which makes cornering even easier.
As always, the steering has two settings, with Comfort well-weighted, while Sport adds a little too much heft for most drivers.
This set-up goes a step further with all-wheel steering, which adds a lot of the agility. It sees the rear wheels turn in the opposite direction to their front counterparts at low speed to improve manoeuvrability, and in the same direction at high speed to optimise stability.
And, of course, the rear-biased M xDrive all-wheel-drive system provides prodigious grip alongside the Active M Differential, which makes the rear axle a better performer when powering out of corners with earnest.
As we found out on some very icy country roads, the electronics let the driver get away with just enough fun (or terror) before stepping in and keep things on track. M xDrive also has a looser Sport setting, but needless to say, we didn’t explore due to the prevailing conditions.
Given the outputs on hand, the X5 M Competition comes with an M Compound Brake system that consists of massive 395mm front and 380mm brakes discs with six- and single-piston callipers respectively.
Braking performance is strong – and it needs to be – but of greater interest is this set-up’s two pedal-feel options: Comfort and Sport. The former is relatively soft from the get-go, while the latter gives plenty of initial resistance, which is right up our alley.
Comfortable and (believe it or not) athletic, sums it up. And the only thing stopping me from throwing in another word such as effortless is the forward visibility, which is what I noticed the moment I steered it out of the dealership and into the traffic.
But first let me give you the comfortable and athletic good news. The Bentayga felt nothing like it looked to drive – my eyes told me it should be more sumo wrestler than ninja to steer but they were wrong.
Despite the hulking dimensions and not insignificant weight, the Bentayga V8 felt surprisingly lithe with great handling for an SUV this size.
That the Urus, which I test drove a few weeks beforehand, also felt athletic seemed less a surprise in that the styling suggested it was agile and quick.
Thing is it shouldn’t be a surprise given the Urus and Bentley share the same MLB EVO platform.
Four standard drive modes let me change the character of the Bentayga V8 from 'Comfort' to 'Sport'. There’s also a ‘B’ mode which is a mix of throttle response, suspension and steering setting which Bentley nominates as the best for all-round driving conditions. Or you can ‘build-you-own’ drive mode in the 'Custom' setting.
Keeping the comfort mode on makes the ride composed and supple. Self-levelling air suspension with continuous damping is standard but flick the dial to Sport and the suspension firms, but not to the point where the ride is compromised.
I spent most of my almost 200 kilometres testing it in Sport mode which did nothing to help fuel economy but made my ears happy with the V8 burble.
Now, about that forward visibility. The design of the Bentayga’s nose is the cause of my issue here; specifically the way the wheel guards are stepped down out of view from the bonnet.
All I knew was that I was about 100mm wider that it looked from the driver’s seat – I don’t like that kind of guess work when piloting half a million dollars down a narrow street or car park. As you’ll see in the video I came up with a solution to the issue.
I’m not going to let that nose get in the way of a poor score, however. Besides owners will get used to it after a while.
Aside from that, the Bentayga was quite easy to parallel park with light steering and good rearward visibility and large wing mirrors, while multi storey shopping centre car parks were also surprisingly fuss free to steering through – this is after all not an overly long large SUV.
There was one ‘drive thru’ excursion and again I’m happy to report I emerged with hamburgers and without scratches at the other end.
So, I’m happy to throw effortless in there after all and you can add serene – that cabin felt bank vault-like insulated from the outside world. Don’t ask me how I know that.
ANCAP awarded the diesel versions of the X5 a maximum five-star safety rating in 2018. As such, the petrol X5 M Competition is currently unrated.
Advanced driver-assist systems impressively extend to autonomous emergency braking, lane-keep and steering assist, blind-spot monitoring, front and rear cross-traffic alert, adaptive cruise control with stop and go functionality, speed-limit recognition, high-beam assist, driver attention alert, tyre pressure and temperature monitoring, hill-start assist, hill-descent control, park assist, surround-view cameras, front and rear parking sensors, among others. Yep, there’s not much missing here…
Other standard safety equipment includes seven airbags (dual front, side and curtain plus driver’s knee), the usual electronic stability and traction control systems, anti-lock brakes (ABS) and brake assist (BA), among others.
The Bentayga V8 has not been assessed by ANCAP testing but being based on the same platform as the five-star rated Audi Q7 I have no reason to suspect the Bentley would perform any differently and not be safe from a structural perspective.
We’re tough on budget cars that don’t come standard with AEB and likewise on high-end vehicles, and the Bentley Bentayga V8 doesn’t escape here.
AEB is not standard on the Bentayga V8 and if you want other forms of advanced safety equipment such as lane keeping assistance, adaptive cruise control and rear cross traffic alert you’ll have to option them across two packages – the 'City Specification' for $12,042 and the 'Touring Specification' which was fitted to our car for $16,402.
The Touring specification adds adaptive cruise, lane keeping assistance, AEB, Night Vision and a head-up display.
For child seats you’ll find two ISOFIX points and two top tether anchor points across the second row.
Like all BMW models, the X5 M Competition has a three-year/unlimited-kilometre warranty, which is well behind the five-year standard set by Mercedes-Benz and Genesis in the premium segment.
That said, the X5 M Competition also comes with three years of roadside assistance.
And its service intervals are every 12 months/15,000km, whichever comes first. Several capped-price servicing plans are available, with the regular five-year/80,000km version costing $4134, which, while expensive, is not surprising at this price point.
