Bentley Continental vs BMW 4 Series

What's the difference?

It may not come cheap, isn’t ideal for family buyers and will have you visiting the petrol bowser regularly, but it’s still hard not to love the Continental GT.

It’s an over-the-top car in so many ways, from the dramatic styling to the plush and pampering interior to the effortlessly powerful engine, this is a car that is a pleasure to drive 10km or 10,000km.

It’s certainly not cheap, especially if you start diving into the options list, or the even more costly Mulliner program, but price is relative, of course, and for Bentley buyers purchasing one of these cars isn’t about getting a ‘bargain’ but instead it’s about experiencing the finer things in life.

The BMW M440i xDrive Gran Coupe manages to combine sleek design with a fun-to-drive personality and surprising practicality. It’s a rapid premium, four-door, five-seater offering extra flair, and in this part of the market, good value. But more than anything else it’s got a cracking in-line six under the bonnet.

The most interesting aspect of the third-generation Continental GT design is how similar it looks to the first-generation model launched 20 years ago.

Put the pair side-by-side and you’ll notice the latest model is more refined and features crisper lines and more intricate details, but the overall shape and design themes, such as the grille, headlights, etc, bare a similar family resemblance.

This is a deliberate act from Bentley, choosing an evolutionary styling approach for the Continental GT in the same way Porsche has approached the 911.

As for the specific details of this particular Continental GT S model, there are some key differences between it and the standard GT and GT Azure models that sit beneath it in the range. 

The most notable - even if it is slightly harder to spot on our black test car - is a ‘black pack’ that swaps all the chrome finishes on the exterior to black.

This includes the grille, headlight surrounds, lower bumper grille, window surrounds, door mirror caps and the exhaust tips. The S also adds black sports sills and black-painted alloy wheels.

So, how does this four-door 4 Series differ from a four-door 3 Series? The answer is as plain as the nose on this car’s face.

BMW’s head of design, Adrian van Hooydonk, has been expanding the brand’s signature ‘kidney grille’ in every conceivable direction, and this is the much talked about interpretation adorning all 4 Series models (petrol, hybrid and electric) as well as the M3 sedan.

The new Gran Coupe is longer, wider, and taller than the outgoing model, and the track is broader, front and rear. The wheelbase has also been extended, now a whole 5.0mm longer than the 3 Series.

The DRLs and headlight main beams are LED with laser high beams, immense gills square up the edges of the front clip, while a vent and the strake attached to it stand the car apart. Plus, of course, the doors are frameless. 

One niggle, though. I’m not in love with the slender door handles. It’s hard to get a good grip on them, especially in the wet. 

Standard 19-inch alloy rims are shod with Pirelli P Zero rubber 245/40 fr / 255/40 rr), the roofline slopes distinctly towards the rear, a lip spoiler on the trailing edge of the tailgate is classic BMW, darkened LED tail-lights wrap around the rear corner, and a diffuser-type panel is flanked by large exhaust apertures.

Our car’s ‘Aventurine Red’ finish is a $3850 option, but to my eyes anyway it looks superb.

Exterior trim including the grille frame, front air intake inserts, mirror upper housing, model designation badges, and tailpipe are finished in ‘Cerium Grey’, which I reckon 99.9 per cent of people will see as black. 

The interior will be familiar territory for any current BMW owner, the 12.3-inch digital instrument screen sitting in a compact, hooded binnacle, and partnering with a 10.25-inch multimedia display standing proud of the dash above the broad centre stack. 

The seats are trimmed in top-shelf leather with blue contrast stitching, plus the grippy sports wheel is also wrapped in genuine hide.

BMW calls the finish on the main buttons and controls ‘Galvanic’ which translates to a slick silver metallic look and feel. Configurable ambient interior lighting is a nice touch, and the broad console enhances the driver-focused feel, with a sprinkling of carbon-fibre around the centre console and dash lifting the sense of occasion.

Overall, the interior feels clean and classy with an obvious attention to detail.  

As mentioned earlier, the Continental GT is a two-door, four-seat grand tourer, but while it’s certainly grand, calling it a four seater may be a stretch.

There are two small seats in the rear that can be used if absolutely necessary but anyone in the back won’t feel like they’re in a luxury car because they’ll be cramped for space - even with the roof down.

You could pop small kids in the back in a pinch (and there is a pair of ISOFIX anchor points) but the Continental GT is hardly a family car.

In fact, the Flying Spur is a four-door sedan built on the same underpinnings as the Continental GT, so Bentley does have family buyers covered.

So, let’s keep our attention on the front seats, which is where you want to be in this grand tourer. The seats are comfortable and offer fantastic support, thanks in large part to 12-way electronic adjustment.

To help you enjoy your convertible with the top down regardless of weather, the seats are heated and available with a vent to blow warm or cool air onto your neck.

The seats are just the start, the whole cabin is a blend of modern technology and classic luxury elements.

There’s the media touchscreen, but there’s also a physical button for most functions, so it’s a busy layout but one that will likely appeal to Bentley’s older clientele.

Our test car was fitted with not only the optional sound system but a rotating display, so you can hide the screen away when you’re not using it.

Overall the build quality and attention-to-detail is exceptional, as you’d expect for a car at this price. And it’s really one of the main reasons you buy a Bentley, because it has a level of luxury and quality above brands like Mercedes-Benz and Porsche.

At close to 4.8m long the 4 Series Gran Coupe is a sizeable machine. Up front, the feeling is airy and comfortable, and the rear is surprisingly spacious, especially in light of the car's sloping roofline.

At 183cm I have to fold myself tightly to fit under the low roof, but once inside I have enough room to sit behind the driver’s seat set for my position with more than enough legroom and adequate headroom. Put three full-size adults across the back row, though, and there will be breathing difficulties.

Kids will be fine, however, and individual vents with adjustable temp in the rear was a big plus during a particularly hot test week.

For storage there are generous door bins in the front with room for large bottles, a decent glove box, dual cupholders in the centre console, a reasonable lidded bin (which doubles as a centre armrest), and the wireless device charging bay (forward of the gearshift) makes a handy oddments space when not in use.

In the rear, again the doors feature pockets with room for (medium-size) bottles, there’s a fold down centre armrest with two cupholders, but thanks to the one-piece shells on our test car’s optional M Sport front seats there are no map pockets.

Power and connectivity runs to a USB-A socket and a 12V outlet in the front centre console, as well a USB-C port in the front storage bin, a pair of USB-Cs in the rear, and a 12V outlet in the boot.

Speaking of which, lift the tailgate and with the rear seat upright we were able to fit all three of our suitcases or the beefy CarsGuide pram into the healthy 470-litre (VDA) boot space.

Lower the 40/20/40 split-folding rear seat down and 1290 litres of volume is at your disposal. Plus there are handy bag hooks and tie-down anchors to help secure loose loads.

You can also tow a braked trailer up to 1.8 tonnes (750kg unbraked), but don’t bother looking for a spare of any description, a repair/inflator kit is your only option.

We’re in a zone some way North of $100K here with cost-of-entry running to $115,900, before on-road costs. So, as well as the included powertrain, suspension, and safety tech you should rightfully be expecting a lengthy standard features list.

And the M440i Gran Coupe goes toe-to-toe with its heavyweight Euro competition, featuring three-zone climate control air, adaptive cruise control, ‘Laserlight’ headlights, that 12.3-inch ‘BMW Live cockpit Professional’ instrument display and 10.25-inch ‘Control Display’ multimedia touchscreen managing navigation, the 16-speaker/464W harmon/kardon Surround Sound audio system (with Apple CarPlay and Android Auto integration) and a host of other on-board functions.

There’s also the ‘Vernasca’ Black leather trim, an electric glass sunroof, the leather-trimmed sports steering wheel, the electric sports front seats are heated and there’s wireless charging for compatible devices.

Bentley is renowned for its big, powerful engines, specifically its unique W12. That’s available in the top-of-the-range Continental GT, but the S model we’re driving is motivated by a 4.0-litre twin-turbo V8.

It may not be what Bentley is famous for, but it’s a fantastic engine in its own right and it’s paired to a well-matched eight-speed automatic transmission and an active all-wheel drive system.

Making a very healthy 404kW and 770Nm it has no trouble getting such a big car moving.

Bentley claims the Continental GT S will run 0-100km/h in just 4.1 seconds, which is very rapid and particularly impressive when you realise this car weighs 2335kg.

Under the bonnet is BMW’s (B58) all-alloy 3.0-litre twin-scroll turbo intercooled, in-line six-cylinder engine, driving all four wheels via an eight-speed automatic transmission and electronically controlled clutch pack, as well as an electronic limited-slip differential at the rear.

It features high-pressure direct-injection and BMW’s ‘Valvetronic’ system managing air flow to the intake side, to produce 285kW at a relatively high 5800-6500rpm. But the big punch is 500Nm of peak torque from just 1900rpm all the way to 5000rpm.

The M440i is also a mild-hybrid with a 48-volt starter motor-generator and supplementary battery able to give an 8.0kW kick at low engine speeds.

If you’re looking for a fuel efficient car or are worried about the price of premium unleaded at your local service station, the Continental GT is not for you.

In an entirely unsurprising way, this two-tonne, twin-turbo V8 luxury car is not a fuel-sipping proposition.

Even the official combined urban/highway cycle is 12.5 litres per 100km, which is thirsty.

But if you’re spending most of your time around town, rather than driving to your country weekender, you’ll probably be looking at returns in the mid to high teens, based on our experience.

We saw an average of 16.7L/100km on the car’s long-term trip computer that included more than 1400km of driving.

Fortunately it has a 90-litre tank, which translates to a theoretical driving range of 720km - as long as you can hit the official claim.

BMW’s official fuel economy figure for the M440i xDrive Gran Coupe, on the ADR 81/02 - urban, extra-urban cycle, is 8.2L/100km, the 3.0-litre turbo six-cylinder emitting 187g/km of C02 in the process.

Stop/start is standard, and we saw an average of 11.1L/100km over city, B-road and freeway running during a week with the car.

With the 59-litre tank brimmed (with minimum 95RON premium unleaded) that real-world test number translates to a range of around 530km.  

There’s a duality to the driving experience of the Continental GT, as it manages to blend its obvious luxury focus with a genuinely dynamic edge that makes it a true grand tourer.

The combination of the powerful engine and air suspension means it possesses a laid back personality and effortless nature around town.

The engine delivers its performance with ease, moving this big car rapidly whenever you put your foot down, so you can jump into gaps in traffic or make a brisk getaway from the lights.

It soaks up all the bumps and imperfections on the road with minimal fuss, too, despite our test car riding on 22-inch wheels, so you feel cosseted inside the plush cabin.

However, if you find yourself on the open road, the Continental GT S is equally at home.

Dial up the ‘Sport’ drive mode and the engine feels more responsive, the steering is more direct and the suspension is more taut but still compliant.

It makes this a really fun car to drive on a fast, sweeping rural road, where you can let the engine stretch its legs.

Because of its size it’s not as enjoyable on a twisty road with lots of changes of direction, though.

But for enjoying an opulent daily commute or a weekend drive in the countryside the Continental GT S is a great companion.

BMW says the M440i xDrive Gran Coupe will accelerate from 0-100km/h in 4.7sec, and I reckon the threshold for a properly quick car is sub-five seconds.

The 3.0-litre turbo six develops its peak power of 285kW between a relatively lofty 5800-6500rpm, but the big number is a solid 500Nm punch of pulling power delivered between 1900-5000rpm.

Squeeze the throttle pedal pretty much anywhere in the rev range and the response is glorious. Rapid acceleration accompanied by raucous engine noise and rorty exhaust note (albeit with some synthetic support). Various pops and bangs in the Sport settings add extra entertainment.. 

The eight-speed auto gets some electric support from the mild-hybrid system to fill the torque gap on up shifts, and the result is a conventional torque-converter transmission that behaves like a dual-clutch.

Shifts are seamless in general driving, and satisfyingly quick in a more aggressive mode, the wheel-mounted paddles dialing up the fun in manual changes. 

Suspension is double wishbone front and multi-link rear with the standard ‘Adaptive M Suspension’ built around an adaptive damper set-up.

The change between the ‘Comfort’ setting to the ‘Sport’ or ‘Sport+’ calibration is close to instant and makes a discernible difference, especially in terms of ride comfort.

I found the best ‘Individual Sport’ arrangement to be damping in Comfort, with the steering engine and transmission in Sport. The car flows so beautifully through corners with urgent response from the powertrain.

By all means dial up the suspension if you’re having a real crack, but the car feels superbly balanced, stable and predictable in Comfort (front to rear weight distribution is 50:50).

The electrically-assisted variable-ratio steering is nicely weighted with good road feel, and the grippy sports steering wheel is a nice point of contact.

The xDrive AWD system’s default setting is rear-biased, although it will push most of the drive forward when required. But the RWD feel is unmistakable. 

The M440i weighs in at around 1.9 tonnes but feels lighter and more nimble than that figure would typically indicate.  

A standard electronically-controlled M Sport limited-slip differential puts the power down confidently. I have a favourite LSD test corner on my regular evaluation drive, a sharply twisting and rising left-hander.

Rolling into it in a low gear before planting the throttle mid-corner, the car simply hunkers down without a hint of fuss (or traction loss) as it rockets out the other side.

Optional M Sport front seats ($2000) provide comfort and firm location in equal measure and in terms of ergonomics BMW knows how to focus on the driver and set-up an efficient environment. Key controls are perfectly positioned and simple to operate.

I have an issue with the ‘Lane Departure Warning’ function, however, which is too quick to intervene and overly intrusive when it does so. I turned the ‘Steering Intervention’ function off. You can dial down steering wheel vibration warnings, too.

The standard M Sport brakes feature big vented rotors front and rear, with fixed four-piston front calipers doing the bulk of the work. They’re strong but don’t bite or release too aggressively. It’s easy to grease in a smooth application. 

Active crash-avoidance tech in the M440i xDrive Grand Coupe is impressive with AEB standard, as well as lots of assistants and warnings, namely: ‘Steering and Lane Control Assistant’, ‘Cross Traffic Warning’ (front and rear), ‘Lane Keeping Assistant’ (with ‘Lane Departure Warning’ and ‘Lane Change Warning’), ‘Crossroads Warning’, ‘Evasion Assistant’, and ‘Parking Assistant Plus’ (including ‘3D Surround View and Reversing Assistant’).

If an impact is unavoidable there are six airbags on-board (driver and front passenger front and side, plus side curtains) as well three top tethers and two ISOFIX positions for child seats in the second row.

Plus an ‘Intelligent Emergency Call’ function automatically dials back-to-base if the car has been involved in a crash, and a comprehensive first aid kit is on-board. 

The BMW scored a maximum five-star ANCAP assessment in 2019.

Another surprising feature of the Bentley range is the company’s three-year, unlimited kilometre warranty, which feels surprisingly short in this day and age - especially for a brand that takes pride in its carefully built cars.

There is a 10-year warranty available as an optional extra, but it feels like that should be standard if the company is willing to stand by its products anyway and owners are paying such a premium for their cars upfront. 

The good news is all Bentley models are covered by a five-year servicing plan (intervals are 12 months/16,000km) which is included in the cost of the car.

As you should expect from such 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.

The M440i Gran Coupe is covered by BMW’s three-year/unlimited km warranty (including paintwork), as well as 12-year/unlimited km anti-corrosion (perforation) cover. 

That’s off the premium market pace now with Genesis, Jaguar, and Mercedes-Benz at five years/unlimited km and Lexus set to join them from January 1st, 2022. 

That said, roadside assistance is provided for the duration of the main warranty, but it’s worth noting “rattles and squeaks” are only covered for one year.

Service is condition-based, the car telling you when maintenance is required, and a range of service packages are available. The basic plan covering a 4 Series for five years/80,000km comes in at $1750.
