BMW 4 Series vs Suzuki Swift

What's the difference?

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.

So, there you have it. A brief look at the new, sixth-gen Swift.

Better where it needs to be, the supermini survivor still remains competitively priced, with loads of new efficiency and safety tech that buyers will appreciate.

But, most of all, the Suzuki still feels, drives and rewards like the old model used to. It just does so with more sophistication.  

As inexpensive city cars continue to fade, the new Swift continues 41 years of providing a fun, affordable and dependable solution, in a vibrant and desirable package.

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.  

At first glance, the new one looks a lot like the old one. Short overhangs, long wheelbase, upright A-pillars, that signature 'floating' roof. This could be nothing else but a Swift.

Obviously, though, every single panel has changed, resulting in a stronger, quieter and more aerodynamic body.

Helping communicate this is a new and very definite crease line added to create a more-pronounced shoulder. The bonnet seems to be more clamshell-like and the nose is squarer, too. Indeed, everything about the overall styling seems to be more upright.

Debate is already raging in some circles. Is the new Swift too fussy? Too conservative? Has it lost the playful boldness of the proceeding version's gently-sculptured sides and hidden rear-door handles? Are the proportions slightly out now? Has the previous design integrity and oneness of vision been diluted? Does the 2017 predecessor look better?

Underneath, the platform is essentially the same, while overall dimensions are largely identical except for a 20mm stretch and 25mm roof lift. Length, width, height and wheelbase numbers 3860mm, 1735mm, 1520mm and 2450mm, respectively.

Happily, the aesthetic changes inside are likely to please rather than perplex, and even delight rather than divide opinion.

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.

From a packaging perspective, the latest Swift carries on from before, and that’s no bad thing. It remains exceptionally roomy as well as practical.

To that end, entry and egress are easy, there’s a sense of spaciousness thanks to deep windows, a high ceiling and lofty seating, while the latter also helps provide an agreeable driving position. Storage and ventilation are provided in abundance.

For many people, the dash redesign reflects a big change in attitude, having finally grown up and away from the previous cheap and cheerful look. Highlights include pleasing seat fabrics, interesting textures and a sense of quality craftspersonship, within a stylish and sweeping design. After 41 years, the Swift has matured gracefully.

It’s also worth pointing out the super-clear analogue instrumentation dials, supported by a digital speedo and configurable trip computer data; actual buttons for the heating and air-conditioning system and – joy of joys – a handbrake lever.

Plus, if you want to turn off the various beeps from the driver-assist systems, physical buttons are but a simple press away. No distracting sub-menu searches within fiddly touchscreens here, thanks.

Except if you want to change the volume because you’ll need to prod the screen after all. The knob is always the better option, Suzuki.

What else? The rear bench area is a little plain but surprisingly roomy for this class of light car. Probably more so than a Corolla provided back in the early 2000s, with a decent level of cushy support for two people or three at a squeeze.

Given the extra specification, even the cheapest grade is all the Swift you’ll need. A sign of a democratic car.

But keep in mind the base variant no longer comes with a driver’s seat adjuster, passenger vanity mirror and multiple USB ports found in the Plus and GLX versions, while it is alone with a clammy plastic rather than leather-sheathed steering wheel rim.

At least cargo capacity edges up, by 23 litres to 265L (VDA), and that’s just under the luggage cover, thanks to some clever repackaging of a now-lower boot floor and internal tailgate panels. Drop the rear backrests and that expands to 569L.

Note, however, that for the Swift to achieve its sensationally low kerb weight that starts from just 919kg (up around 50kg), it now uses a fiddly and frankly-inadequate tyre repair kit. Thankfully, Suzuki offers that space-saver spare, at extra cost (and mass) of course.

Still, keeping those kilos low pays high dividends when it comes to performance and economy.

So. Why are there so few affordable city-sized superminis like the Swift?

Just 10 years ago, the Swift had at least 25 rivals under $25,000. Today that’s phonetically as well as literally down "t(w)o" "three" – namely, the ageing but still-surprisingly-spry Mazda2 and intriguing all-new MG 3, as well as Australia’s sole sub-$20K new car, Kia's darling Picanto.

Many of the Class of 2014 have since morphed into pint-sized crossover hatchbacks like Suzuki’s soon-to-be-discontinued Ignis, the Hyundai Venue and Kia Stonic. And if you must, there are also the cheerless MG ZS and ancient Mitsubishi ASX biggish-small SUVs – but they’re cheapo for a reason.

Unlike the latest Swift... which, from $24,490 drive-away, is more than reasonably cheap, since it introduces some electrification tech across the whole range, while still being around the same price as the old base GL.

This now makes the new Swift Australia’s cheapest 'hybrid'.

Granted, despite wearing the Hybrid badge on every grade, it’s just a mild hybrid system, but one that provides extra electrification to usefully boost performance and economy for the all-new powertrain and revised transmissions. More on all that later.

What else? The base Swift at last gains LED lights, telescopic as well as tilt steering adjustment and important driver-assist safety like Autonomous Emergency Braking (AEB), along with lane-support systems, adaptive cruise control and rear parking sensors.

Also included now are keyless entry/start, a 9.0-inch touchscreen as part of a new multimedia set-up, wireless for Apple CarPlay (but not for the Android Auto), a digital radio, heated mirrors, traffic sign recognition, auto high beams and an alarm.

And there's more. The entry-level Swift Hybrid is also class unique in offering a manual gearbox. Good on you, Suzuki.

Not for you? Don't worry, because the Hybrid auto that is expected to be the bestseller starts from $26,990, drive-away. For the record, that’s only about $1000 more than the equivalent old version but with all that extra gear to boot.

But, beware, the base-model Hybrid alone lacks a few items that may or may not have been standard in the outgoing Swift, such as a driver’s seat-height adjuster, leather-wrapped steering wheel, privacy glass, alloy wheels, front passenger vanity mirror, front-seat map pockets, multiple USB charging outlets and a spare wheel (though you can pay extra for one as the wheel-well remains).

All of the above, except the missing spare, are included in the new Hybrid Plus auto grade, from $28,490 drive-away, along with heated front seats and additional driver-assist tech like a blind-spot monitor. We’ll get into more detail in the Safety section below.

Finally, there’s the Hybrid GLX auto, with its wireless phone charger, folding exterior mirrors, steering wheel paddle shifters, climate control, glossy alloys and more from $29,490, drive-away.

Sadly, the terrific old GLX 'BoosterJet' three-cylinder turbo is no more, and there might not even be a new Swift Sport to continue the GTi hot-hatch legacy.

Still, Suzuki’s managed to keep the entire range under $30K drive-away, despite big changes inside and out. Let’s check those out.

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 there’s one area where Suzuki shines, that’s in making sweet little engines, and the new, chain-driven, 1197cc 1.2-litre mild hybrid three-cylinder petrol unit is no exception.

Now, on paper, 61kW at 5700rpm and 112Nm at 4500rpm may seem slightly lacking. A Mazda2 manages to make nearly 35 and 30 per cent more power and torque, respectively.

But the Swift's new 'ISG' integrated starter/generator/electric motor unit delivers an additional 2.3kW and 60Nm.

Combined with the hatchback's comparative lightness, it makes for a sufficient power-to-weight ratio of between 63 and 66kW per tonne.

Or, in other words, it provides some welcome extra low-down muscle.

Drive is naturally sent to the front wheels, via either a light-yet-positive shifting five-speed manual gearbox, or new CVT auto. Both have been heavily revised in their new roles serving the mild-hybrid powertrain.

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.  

The latest Swift’s maturity does not end with its suave cabin presentation.

Prioritising high economy and subsequently low pollution, this Euro 6d-rated three-pot hybrid powertrain promises an astonishing combined fuel-consumption average of just 3.8 litres per 100km for the manual, and slightly more for the CVT at 4.0L/100km.

The results are 78 and 80 grams per kilometre of carbon dioxide emissions, respectively, along with around 970km between refills of the meagre 37L fuel tank.

These facts somewhat ease the pain of the need for more-expensive 95 RON premium unleaded petrol instead of the regular brew. High-tech solutions do require superior fuel, after all.

With just 70km on our ultra-tight test car’s odometer, the trip computer’s 6.7L readout is likely no indicator of the frugality we’re expecting to come.

So, how are such low consumption figures attainable? Along with better aerodynamics and a low kerb weight, the latest Swift Hybrid’s ISG hybrid unit generates supplementary electricity under acceleration, to ease the engine’s reliance on petrol.

It also recharges the 12-volt lithium-ion battery that lives beneath the front passenger-seat floor off-throttle via regenerative braking.

Note that the Suzuki never drives purely on electricity.

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. 

No Swift since 2004’s new-millennium redesign has been anything less than fun to punt around. A focus on driving pleasure and superior dynamics has helped make each version a cut-above most rivals.

Losing the smooth old 1.2-litre four-cylinder engine in the name of low consumption and emissions is a noble move. But how does this translate out in the real world, especially with a Swift fan behind the wheel?

It's mostly great, actually.

Losing a cylinder results in a slightly less creamy power delivery, especially as it’s accompanied by a distinctive three-cylinder exhaust-note thrum. But that’s still in keeping with the Swift’s endearingly sporty character.

Better still, even with all the examples we tested showing barely more than delivery mileage on the odometer, there seems to be more than enough grunt to please driving enthusiasts.

While not wanting to tax engines that weren’t even run-in yet, the charming revvy eagerness and instant throttle response remains, along with a discernible extra kick when accelerating away from standstill.

Even being so new, our Swifts proved to be lively, lusty and surprisingly rapid performers. We can’t wait to test run-in examples!

The five-speed manual is deliciously well-oiled and precise, immersing the driver into the Swift experience on another level compared to the CVT auto, which still manages to impress by responding quickly and effortlessly, without feeling laggy or droney. A lot like the old version.

Suzuki is making a lot of noise over how agile yet comfortable the newcomer’s handling and ride qualities are, as a result of improved rigidity and noise-dampening measures.

The Swift’s MacPherson-style front struts and torsion beam rear suspension systems have been revised with stronger and quieter mounts for better performance, while the electric steering has been retuned for greater feel and linearity. 

The result? Even our limited time behind the wheel revealed tactile and precise steering, composed handling and extraordinary isolation from the road below for a car barely weighing 950kg (at most).

Combined with the nuanced driver-assist safety tech that rarely interrupted the fun, the latest Swift is a cheerfully animated, nimble and rewarding experience... and one that stands out all the more for evolving while so many other like-minded rivals like the Ford Fiesta have sadly fallen away.

Bravo, Suzuki. Generation Number Six remains the enthusiast driver’s choice, and a hybrid bargain to boot.

The latest, sixth-generation Swift has yet to be crash-tested by ANCAP.

Even the base Hybrid now includes driver-assist safety like AEB that includes night and day pedestrian and cyclist detection as standard, along with lane-departure warning, lane-keep assist, 'Weaving Alert' (a driver-drowsiness warning prompt), rear parking sensors, traffic-sign recognition, a reverse camera, automatic high beams and adaptive cruise control.

You’ll need to go Hybrid Plus for rear-cross traffic alert and blind-spot warning tech, though.

Note that Suzuki does not supply information about the AEB and other driver-assist tech’s operating parameters.

Also fitted are six airbags (dual front, dual front side and curtain), electronic stability control, anti-lock brakes with electronic brake-force distribution and brake-assist.

The rear seats also contain a trio of child-seat tether anchorages, as well as an outboard pair of ISOFIX attachments.

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. 

Suzuki offers an industry-average five-year/unlimited kilometre warranty and roadside assistance.

Service intervals are every 12 months or 15,000km, while basic capped-price servicing is available, with the website showing pricing for the first five years and 100,000km averaging $391 per workshop visit.
