Bentley Flying Spur vs BMW M5

What's the difference?

There are two schools of thought when it comes to plug-in hybrids like the Flying Spur. Some people believe they provide the best of both worlds, combining elements of an EV and ICE vehicle. Others believe it’s a compromise, which requires you to carry around an electric motor and batteries you may not use much of the time.

The truth is the value of a PHEV will largely depend on how you use it. If you have a short commute and access to regular charging then it should work well for your needs, but if you need to drive longer distances and won’t charge it regularly it doesn’t make sense.

What isn’t up for debate, though, is how luxurious and premium the Flying Spur is. Sure, there are some surprisingly non-standard items that require you to spend above and beyond the already sizeable asking price, but if you do you’ll be rewarded with a car that is opulent and efficient.

The term bigger is better doesn't often apply to performance cars, but it fits the M5 Competition perfectly. Big inside, but small outside when it matters, BMW's new performance flagship might be expensive, but there's no shortage of bang for those bucks.

Bentley isn’t exactly targeting a youthful audience with this car so there’s a, shall we say, traditional design aesthetic to the Flying Spur. This is a car that’s meant to ooze sophistication and luxury and it does that with its appearance.

From the signature Bentley grille, glistening in shiny chrome, to the intricate, jewel-like detail of the headlights, through the carefully sculpted flanks and to the tapered tail the Flying Spur is all about old-school luxury.

But there are some nice modern touches, highlighted by the ‘Flying B’ bonnet mascot, which not only can retract for improved safety, but at night it illuminates when you unlock the car, lending that touch of luxury that tells you that this is a step above most rivals.

Let’s start with the new stuff, shall we? The BMW M5 Competition gets a new colour ('Frozen Dark Silver'), as well as new 20-inch (and lightweight) alloy wheel designs, and the grille, aero-designed wing mirrors and boot lip are finished in high-gloss black. The quad exhaust pipes are a black, too, as is the rear diffuser. Elsewhere outside, though, it’s the more muscular 5 Series of old.

Parked next to the much smaller M2, you quickly realise just how much bulk the M5 is carrying. It stretches 4966mm in length and 1903mm in width, and it looks every centimetre of those dimensions in the metal.

Climb inside, and you’re greeted with the familiar BMW interior design, with a huge centre screen, digital driver’s binnacle and a spaceship-level number of buttons surrounding the shift lever. The M5 Competition also arrives with full leather (seats and dash) trim, with carbon-effect dash inserts and aluminium pedal and foot rest trims.

Is it the most adventurous design treatment, inside or out, that we’ve ever seen? Well, no. But it looks polished and premium outside, and feels plenty comfortable inside.

Not surprisingly, there’s generous room inside this modern limousine. The Flying Spur is one of those cars you’d enjoy being driven in, arguably even more than driving.

But before we talk about the back seat accommodations, let’s start in the driver’s seat.

The front of the cabin is another display of traditional luxury with a blend of modern technology. There is a veritable smorgasbord of premium materials - fine leather, bright metals and genuine wood veneers. 

The steering wheel is thick and wrapped in very nice leather so it feels great, as does the supple hide that covers the soft but supportive seat.

In front of the driver is a digital dashboard but the graphics are traditional round dials for the speedo and tacho, with a central area for other key information, such as the use of the hybrid system.

For the trained eye there are some giveaways that Bentley is part of the Volkswagen Group, the way some of the graphics are presented, some of the switchgear and other small elements - but nothing overt.

Space in the rear is very good, with more-than-adequate head, knee and legroom, but it’s not expansive as you’ll find in an extended-wheelbase vehicle, like its Bentayga SUV sibling.

Still, those in the rear are well looked after, elevating the Flying Spur beyond what you’ll typically find in a ‘luxury car’ - like those from the ‘big three’ German brands.

There are pillow-like headrests, for example, as well as plenty more premium materials and leather-lined surfaces.

But, again, a lot of the items fitted to our test car were cost options, such as the panoramic sunroof, rear window sun blinds and vanity mirrors that flip down from the ceiling.

Boot space is another surprising element of the Flying Spur, because despite the overall size of the car, it measures just 351 litres. For comparison, the Toyota Corolla sedan has a 470-litre boot.

It’s oddly shaped too, with space lost to the wheel arches and other hidden hardware, with even more room given up for the large charging cable bag.

As far as performance cars go, the M5 Competition is a rolling Swiss Army Knife. For one, it’s bloody massive, which pays considerable dividends for passengers. 

Up-front, the seats are far enough apart to ensure you’ll be rubbing shoulders with exactly nobody. The centre console Is super wide (all the better for fitting all those buttons), allowing for a sizeable centre storage bin, joined by two cupholders and a second storage bin in front of the shifter which is also home to your USB, power and 'aux-in' connections.

In the back, there’s business-class levels of leg and headroom, and you can even fit another whole adult in the centre seat if you’re so inclined. The pull-down seat divider is home to two extra cupholders, sitting in front of a thick armrest, and the rear air vents get their own temperature controls. There’s an ISOFIX attachment point in each window seat, too. Pop the capacious boot and you’ll find 530 litres of storage space.

Parking the M5 Competition on your driveway will require a $229,000 investment. That's not chump change, and a considerable jump over the regular M5, which arrived (in launch-edition guise) wearing a $199,529 price tag.

Outside, that money buys you new and lightweight 20-inch alloys, LED headlights with auto-dipping and active cornering, keyless entry and a four-tipped sports exhaust. Inside, expect a 'full leather' interior (seats, dash and door inserts),a nav-equipped screen which pairs with a 16-speaker stereo (but Apple CarPlay is a cost option) and dual-zone climate control.

Performance wise, M-designed variable dampers, a lightweight carbon-composite roof and a M sports exhaust all join the standard features list. Still, $30,000 is fair jump over the standard (and well equipped) M5. But if money is no object, you'll be buying plenty of fun. 

This is obviously the centrepiece of the Flying Spur Hybrid and under the bonnet you’ll find a 2.9-litre twin-turbocharged V6 petrol engine paired with an electric motor and 18kWh lithium-ion battery.

The petrol engine makes 306kW/550Nm on its own, with the electric motor good for 100kW/400Nm and combined Bentley claims the powertrain produces 400kW/750Nm.

That power is sent to all four wheels via an eight-speed dual-clutch auto transmission.

Bentley claims the Flying Spur Hybrid is quick, as well as efficient, sprinting from 0-100km/h in just 4.3 seconds, with top speed rated at 285km/h.

Yes, our all-electric future feels inevitable. And yes, there’s much fun and performance to be had from battery-powered EVs. But you can’t help but hope that future is a Star Wars style far, far away when you get acquainted with the BMW M5 Competition’s monstrous twin-turbo V8.

It’s good for a wondrous 460kW (up 19kW on the regular M5) and 750Nm. Both of which are big numbers, which are fed to all four wheels via an eight-speed 'M Steptronic' automatic. Happily, you can, at the push of some buttons, make the M5 a rear-driver again. It’s slower, but damn if it ain’t much more fun.

As a result, the performance numbers need to be seen (or better yet; felt) to be believed. The near-two-tonne M5 Competition will blaze from 0-100km/h in 3.3secs, 0-200km/h in 10.8secs, and push on to a limited top speed of 250km/h (or 305km/h, provided you do some BMW driver training).

Fuel consumption and electric driving range are always tricky to judge with plug-in hybrids. The official testing cycle favours the combination of electric and petrol power resulting in an official combined cycle figure that’s difficult to hit in the real world.

As was the case with the Flying Spur Hybrid, which has claimed figures of 3.3L/100km, but we could only reach 6.5L/100km during our time in the car.

To be fair, less than 7.0L/100km for such a big, heavy and powerful car is still an impressive return, but it’s well short of the claim.

In terms of electric-only range and the energy consumption of the battery, Bentley claims an EV driving range of 40km, which we also found hard to manage during our test drive. 

The claimed energy use of 9.2kWh/100km is optimistic, though, with the car’s computer telling us it was actually 22.3kWh/100km.

Overall, Bentley claims the Flying Spur Hybrid has a maximum driving range of 804km thanks to the combination of electric and petrol power. 

Well, BMW tells us you’ll return 10.7-10.8 litres per hundred kilometres on the combined cycle. But we would suggest that’s unlikely, unless you have Miss Daisy lounging in the back seat. Drive it like you definitely will drive it, and you can expect to pay for that privilege at the pump. 

Emissions are a claimed 243-246g/km of CO2, and the M5 Competition’s 68-litre tank will demand a premium unleaded petrol.

Climbing aboard and closing the heavy door with a thud, the Flying Spur feels isolated from the outside world before you’ve even turned the powertrain on. It adds that feeling of luxury and refinements that few other cars - and certainly few sedans - can claim these days.

Before you start driving you can select which version of the powertrain you’d like to use, with the ability to switch to all-electric power, a combination of petrol and electric or biased towards petrol to charge the battery.

In hybrid mode the Flying Spur manages which element of the powertrain it uses, typically using the electric motor to get you off the mark and boost performance on the move but allowing the petrol engine to do most of the heavy lifting.

Regardless of the details, it certainly provides the performance you expect from a car like a Bentley. It has the kind of effortless performance that means, despite its size, it never labours or struggles to close a gap or burst forward with urgency.

However, it’s electric mode that seems to fit the nature of the Bentley best - quiet, refined and powerful. Which makes sense.

Electric motors are so well suited to luxury cars that it's no surprise Bentley has committed to going all-electric by the end of the decade.

It’s a shame, then, that the 40km of range runs out quicker than expected and leaves you leaning on the petrol engine again.

Things this large simply shouldn’t be this potent. Like John Goodman suddenly toppling Usain Bolt at the Olympics, the BMW M5 Competition is bulk-defyingly good at the fast stuff.

The secret is its ability to hide those sprawling dimensions on a race circuit or twisting road. BMW’s engineers have poured plenty of work into stiffening the chassis of the M5 Competition, from new anti-roll mounts to additional under-bonnet bracing, to make the brand’s biggest performance sedan feel more lithe and responsive when pushed. 

And while its size never vanishes completely - and you find yourself praying you don’t encounter oncoming traffic on skinnier roads - engaging the Competition’s sportiest settings unlocks a Copperfield-level vanishing act.

The engine helps too, of course, pushing the M5 along with staggering ease, even when you’re pottering at suburban speeds. But really flatten your foot and the big V8 will force you to reassess your knowledge of physics. It’s really very fast, the Competition, the power flowing uninterrupted to the tyres, the engine still very willing to deliver more oomph long after your courage has jumped ship. 

The steering, direct though it is, lacks some natural feel, but you are always left with the impression that the Competition is going to go where you point it.

More fun stuff? Well, you can switch the traction control to a half-off setting, allowing for some smoking, drifting heroics before it drags you back into line. BMW calls it M mode, and it’s designed to make a hero of even the most ham-fisted of pilots, myself included. The braver still can deactivate traction control all together which, combined with rear-wheel-drive mode, turns the M5 Competition into the biggest and possibly most expensive drift car of all time .

Away from the track, though, the Competition version of the M5 is almost as good as transforming into a comfortable everyday commuter as its less hairy siblings. The adaptive suspension can be softened, and the steering lightened, to make toppling traffic a doddle. 

The keen-eyed among you might well have noticed we’re yet to touch on any major downsides of the drive experience. And you'd be correct. 

BMW is yet to confirm full specifications for the M5 Competition, but you can expect the safety offering to largely mirror that of the regular M5. And while the performance variant has not been crash tested, the regular 5 Series was awarded the maximum five-star safety rating.

Expect dual front, side and curtain airbags, as well as a knee bag for the driver, and a parking camera. You'll also find AEB, active cruise (which allows for brief spells of autonomy), thanks to its lane-keep assist. 

Another surprising element of the Bentley ownership experience is the relatively short warranty, at least by modern standards.

Like every other model in the range, it’s only covered for three years (but unlimited kilometres), which is short of the five years most other brands offer, and curious given the high standard to which these cars are built. 

However, the Flying Spur Hybrid is covered by a five-year servicing plan - with 12 months/16,000km intervals - which is included in the cost of the car.

Befitting Bentley’s status as a premium brand, the local dealer will arrange to collect and return the car when servicing is required, and a loan car can be arranged if required so the owner isn’t inconvenienced.

The ownership package is yet to be confirmed, the M5 Competition will be covered by BMW’s three-year/unlimited kilometre warranty. 

Service intervals are condition, rather than time or distance, based, so the car will tell you when servicing is required.
