BMW 4 series
Life comes at you fast, especially in the automotive industry, where model lifecycles are becoming shorter as each new generation comes and goes.
Take the BMW 4 Series for instance. It’s been a segment stalwart since 2013, but the current model’s time in the sun is finally coming to an end a little later this year.
And that got us thinking whether or not the old saying rings true in this context. So, we put the flagship 440i coupe to test to find out if the older you get, the wiser you are.

Peter Anderson road tests and reviews the 2016 Mercedes-AMG SL63 with specs, fuel consumption and verdict.
Well. They don't make cars like this anymore, do they? Time was, a big coupe or convertible were de rigeur for the well-heeled banker, with 12 cylinders almost a given and fuel consumption measured in super tankers, or more likely just not talked about at all.
The world has changed but Mercedes’ SL hasn't. That's not strictly true, of course. The SL63 may drop four of the SL65's 12 cylinders, but at just half a litre smaller and still with twin-turbos it generates the enormous thrust a luxo-barge like this needs. The things that made it an icon are indeed still there - lots of tech, a style all its own and a name everyone recognises.

Is now the right time to buy a 4 Series coupe? With the next-generation model a matter of months away, probably not.
That said, those buyers who decide to park a new ‘old’ 4 Series coupe in their driveway will be very pleased with their purchase.
At the end of the day, the current-generation model is still a cracking sports-luxury coupe, and more so when in 440i form. It’s just that good.
The SL's overall score is somewhat skewed by everyday concerns, and rules are rules - an average punter will find the price of this car somewhat confusing and the devil-may-care attitude to fuel consumption bewildering.
If neither of these things are a problem, then the SL63 makes plenty of - well, not sense, because it's not a particularly clever or considered car - but it fills a niche that not so long ago we all thought would go the way of the dodo.
The fact it sells so few examples is betrayed by some of the cabin amenities and the fact that Mercedes hasn't put much effort into reducing the car's weight to improve its consumption or sharpen up the handling.
The fact it still exists at all is pretty damn cool, though, and for certain people an SL63 purchase is the culmination of a lot of hard work.
If it is your dream car, the SL63 won't disappoint. Everyone who rode with me said it was mightily impressive, but you've got to really want it. When you're not far off buying a Ferrari California T or Aston Martin V12 Vantage S for the money, you'll need a real yearning for the three-pointed star to go this way. And if you do, good luck to you - you've probably worked quite hard to get here.
Would you consider the SL63 over a Ferrari or Aston-Martin? Tell us what you think in the comments below.
BMW 4 series7/10
The first-generation 4 Series coupe has aged relatively well, despite sharing most of its design cues with the superseded sixth-generation 3 Series sedan.
Compared to current BMW models, the 4 Series coupe’s signature kidney grille is small, flanked by angry-looking adaptive headlights with hexagonal daytime running lights, all of which are of the LED variety.
The 440i’s standard M Sport body kit adds to the aggressive styling with chunky front bumper with three large air intakes, the outer two of which also contain the LED fog lights.
Around the side, a strong shoulder line stretches from the front wheel arches to beyond their rear counterparts, while BMW’s Air Curtains split the difference between it and the sporty skirts.
The rear end is the 440i’s simplest angle, although its bumper is spruced up with a dark-grey insert and dual exhaust tailpipes. Predictably, L-shaped LED tail-lights punctuate the styling at the rear.
Inside, the 4 Series coupe is holding up well, but it's still clearly a generation behind most other new BMW models.
That said, it’s a throwback we quite like, particularly iDrive6, which is still arguably BMW’s best multimedia system to date. Powering a floating 8.8-inch touchscreen in this instance, it’s just so intuitive, partly thanks to its rotary controller.
An 8.8-inch digital instrument cluster is a late-life addition for the 440i, and while it looks great with its drive mode-specific views, it lacks the breadth of functionality of Audi’s set-up.
The 4 Series coupe’s cabin is otherwise pretty basic despite its apparent emphasis on sportiness, although the selection of luxurious materials used throughout is top-notch.
The entire dashboard, chunky M Sport steering wheel and old-school handbrake lever are trimmed in high-quality leather, while lower-quality Dakota leather covers the sports seats, armrests and door inserts.
Soft-touch plastic is used for the door shoulders and bins, even in the second row, while hard plastic is limited to the centre console, and gloss-black trim is used on the centre stack’s audio and dual-zone climate control surrounds.
The SL has always been completely unapologetic about its size and seems to be designed to accentuate rather than hide its length and width. The long bonnet screams power and prestige, and get out of my way, and is reminiscent of the little-loved McLaren SLR project of some years ago.
The size of the Mercedes logo on the huge front grille leaves you in little doubt about the brand of car that’s about to pass you at speed and some might say (okay, I would) that its large surface area is a little vulgar.
Like the SLR, the design doesn't seem to have a particularly cohesive strategy, with a number of Mercedes elements from around the traps that climb over each other. Roof up it looks awkward because of the gigantic posterior while with the roof down it looks overly long and, again, tail-heavy.
Folding hardtops are notoriously cumbersome and need a lot of room to hide them, but the silent operation is something to behold.
Elements that are worth deleting if possible are the dodgy 'Biturbo' badges. It's that kind of bling that gets people raising their little finger at you.
BMW 4 series7/10
Measuring 4640mm long, 1825mm wide and 1377mm tall, the 440i coupe is a true mid-sizer, and that means it’s surprisingly practical – for the most part.
Cargo capacity is more than solid, at 445L, but stow the 60/40 split-fold rear bench via a pair of manual latches located in the boot and more storage space is quickly liberated.
To make matters even better, the boot has two bag hooks and four tie-down points, making securing a load a cinch. That said, the high load lip means bulkier items can require a little more effort to accommodate.
Up front, the door bins are large enough for a regular bottle each, while a pair of cupholders separate the gear selector from a seriously shallow storage tray.
The central storage bin is on the shallow side, too, albeit not to the same degree as the dedicated storage tray. That said, much of its space can be taken up by the optional wireless smartphone charger ($200), which was fitted to our test car.
The glovebox tries its best to make up for the lack of genuine in-cabin storage options by being quite large, while storage nets are attached to the backs of the front seats.
Rear occupants can also make use of a large storage tray that resides where a middle seat would otherwise go. They also have access to a fold-down central armrest that incorporates two more cupholders.
Speaking of armrests, the rear side ones are incredibly narrow, leaving tired elbows in a bit of a pickle.
It’s not all bad news in the second row, though, as legroom and toe-room behind our 184cm driving position are very generous, with the former offering several inches of wriggle room.
We’d go as far as to say the rear quarters are comfortable, but that would require ignoring the fact that headroom is seriously compromised with the optional power-operated sunroof ($3000) fitted, with our head pressed firmly against the 440i coupe’s Anthracite roofliner.
Either way, child seats can be fitted in the second row, with ISOFIX anchorage points available for the outer seats. Speaking of which, it’s worth noting ingress and egress to the rear bench isn’t too bad, with the front seats folding forward via manual latches.
Connectivity-wise, two USB-A ports are found in the first row, split between the centre stack and the central storage bin, while three 12V power outlets are spread across the front and rear of the centre console, and the boot.
“Practicality” is about as relevant to this car as a code of ethics is to a drug dealer or a contract killer, because the SL63 buyer is hardly worried about cupholders and boot space. For what it's worth, there are four cupholders in the two-seater cabin (which might explain why owners aren't worried about their liquid carrying prospects) and a minimum boot space of 364 litres and a maximum - with roof up - of 504, which is actually not bad.
Cleverly, there's a little robot-operated luggage cover inside the deep boot that stops your gear from being crushed when the roof goes down.
There's also space in the long doors where you might secrete a bottle of wine that would get a NSW Premier fired if he thanks you for it, and a bin in the console to hide your phone.
Price and features
BMW 4 series7/10
The 440i coupe is priced from $103,200 plus on-road costs, positioning it as a more affordable alternative to its main rivals, the Audi S5 coupe ($105,400) and Mercedes-AMG C43 coupe ($116,500), although it’s not as fully featured.
Standard equipment not already mentioned in the 440i coupe includes dusk-sensing lights, rain-sensing wipers, 19-inch alloy wheels, a mixed set of run-flat tyres (front: 225/40, rear: 255/35) and power-folding side mirrors with heating.
Inside, satellite navigation with live traffic, digital radio, a 600W Harman/Kardon sound system with 16 speakers, a windshield-projected head-up display, keyless entry and start, power-adjustable front seats with heating, an auto-dimming rearview mirror and ambient lighting feature.
It’s difficult to ponder the idea of value when a car is already approaching $400,000 at a rapid rate even before you start piling on the options. On the plus side, for a list price of $368,715 you do get an extremely long list of standard equipment.
Edited highlights include leather on almost every available surface, heated and cooled electric seats with a fan heater for your neck, a B&O stereo that will shatter the windscreen on request, aluminium trim that's real aluminium (mostly), Active Ride suspension, sat nav, dual-zone climate control, active cruise, LED headlights and a huge swag of safety gear.
The 12-speaker stereo also has DVD, limited smartphone integration via Mercedes' COMAND system, a seven-inch screen and, of course, Bluetooth.
Engine & trans
BMW 4 series9/10
The 440i coupe is motivated by a silky smooth 3.0-litre turbo-petrol in-line six-cylinder engine that punches out 240kW of power at 5500rpm and 450Nm of torque from 1380-5000rpm.
An equally silky smooth eight-speed torque-converter automatic transmission exclusively sends drive to the rear wheels – a characteristic that has become a rarity in this segment.
This combination helps the 440i coupe sprint from a standstill to 100km/h in a scant five seconds flat with launch control engaged, according to BMW. Its top speed is electronically limited to 250km/h.
The SL63 is powered by Mercedes’ increasingly famous V8, with two turbos along for the ride to add oomph and cut the car's famous consumption, at least slightly. The 5.5-litre unit produces a massive 430kW and a scarcely believable 900Nm of torque.
All of that heads rearward via a seven-speed dual-clutch transmission that helps sling the 4.6m, 1848kg machine to 100km/h in 4.1 seconds.
BMW 4 series8/10
The 440i coupe will drink a claimed 6.8 litres per 100 kilometres on the combined cycle, while its carbon dioxide emissions are 159 grams per kilometre.
Our week of testing skewed towards city driving over highway stints, and we averaged 8.6L/100km, which is impressive given the six-cylinder performance on offer. And yes, we did put it to use...
The 440i coupe's 60L fuel tank takes 95RON petrol at minimum.
Much as is the case with the price, there's no real way to soften the blow here - the SL63 drinks like a footballer on Mad Monday, except it does it every day. The official combined cycle figure of 10.2L/100km is quite easy to double, as we did, averaging 21L/100km in mostly flowing suburban traffic. In the car’s defence, the accelerator pedal spent a good deal of time near the firewall.
The SL does have stop-start to help reduce its considerable environmental impact.
BMW 4 series8/10
The 440i coupe toe the line between sports car and luxury vehicle very, very well.
The straight-line performance is definitely there thanks to its in-line six-cylinder unit, which is one of our favourite engines in any vehicle – period.
From top to bottom, the 3.0-litre unit is absolutely delicious. Maximum torque kicks in just above idle and remains on tap deep into the top end, at which point a fleeting moment of peak power is just 500rpm away. Needless to say, acceleration is strong.
Remarkably, the engine’s twin-scroll turbo exhibits next to no lag, making for a unit that you truly want to wring out. That said, don’t expect aural pleasure when you do so, as the sound it generates is lacklustre. Yep, no enticing crackles or pops are heard here.
The automatic transmission ties everything together beautifully, providing timely, quick and smooth gear changes on the regular, even without its Sport mode engaged. And, of course, there are paddle-shifters on hand if you want to take matters into your own hands – literally.
Given the 440i coupe’s apparent performance bent, you’d be forgiven for thinking it rides like an unforgiving sports car. Well, the good news is it doesn’t.
While potholes and coarse-chip roads would usually be met with hesitation, the 440i coupe silences the doubters with its composed ride. Can you feel them? Yes, but they’re relatively muted, especially in a car with sporty aspirations, like this one.
Simply put, the 440i coupe loves a twisty stretch of road, where its M Sport brakes (front: four-piston fixed callipers, rear: two-pot floating stoppers) and traditional rear-wheel-drive dynamics come out to play.
This experience is enhanced by its superb electric power steering, which is speed-sensitive, meaning it’s quick at low speed, for improved manoeuvrability, and ‘slow’ at high speed, for improved stability.
We absolutely adore this particular system, mainly because of its perfect weighting and surprising amount of feel. And in a surprise to no-one, it also turns in really well, too.
Of course, if you want to take the 440i coupe’s handling to the next level, you can engage its Sport drive mode, which stiffens up the adaptive dampers for even flatter cornering and adds more heft to the electric power steering. But we’d say both are unnecessary.
There are a number of impressive things about the way the SL drives. Firstly, astronauts will be familiar with the galactic thrust of the V8. It seems endless, seamless and ready to sling the big coupe into the outer atmosphere. Few engines of any kind can match the relentless go on offer in the SL and much of the credit should go to the seven-speed twin-clutch transmission.
Containing a torque figure like the twin-turbo V8's requires a lot of electro-trickery to stop you from being launched off the road. The great thing about all that stuff is that it works unobtrusively and smoothly.
Mashing the carpet in an SL without traction control would create much sound and smoke but little forward progress, such is the twist on tap. The SL has a range of modes from full-nanny (which is meant to keep you on the slippery Alpine road you've chosen to get you to some Swiss ski resort) while turning the dial all the way around to Race loosens the bonds.
It's in this mode you'll have the most fun and it does seem that the intermediate settings are a bit of a waste of time. Race mode does little to diminish the amazing ride quality provided by the active suspension setup, but relaxes the reins on the huge rear tyres. Exiting roundabouts is suddenly a huge laugh, with the tail cheerfully breaking traction and the two-mode exhaust thundering in a most pleasant way.
Better still is that when you jump on the brakes and shift down, the exhaust keeps the show going with angry crackles and pops, with more on the way when you lift off. There's little to match the aural pleasures of a properly tuned V8 and Mercedes has resisted the temptation to quieten it down on the outside and generate a fake noise for the inside. Although that would be stupid in a convertible, if you think about it.
The SL63, despite its AMG badge, isn't about all-out handling, of course. The Ferrari California would definitely show it how it’s done on a winding country road. The SL is more about flow, building momentum and rarely shifting down to second gear. The monstrous torque is enough to keep things rolling but should you wish for a bit more of the exhaust bellow, second is there for the taking.
Hustling the big convertible feels wrong, not because it can't do it, but because it's not really what it's for. Having said that, it offers a kind of fun that nothing else on Earth will provide, not even a Bentley GTC.
With the roof up, the SL63 is a quiet place but not remarkably so. The huge sticky tyres do the cabin's hush no favours, with an annoying roar on a wider range of surfaces than you might expect.
Roof down, it's hardly a paragon of virtue. A lot of wind noise reaches the cabin, even well below the huge speeds the SL can reach. So if you want to talk, it's windows up you'll need to deploy the mesh screen that bridges the roll hoops.
BMW 4 series7/10
Advanced driver-assist systems in the 440i coupe extend to low-speed autonomous emergency braking (AEB) with pedestrian detection, lane departure warning, blind-spot monitoring, adaptive cruise control with stop and go functionality, a manual speed limiter, speed-sign recognition, high-beam assist, park assist, surround-view cameras, front and rear parking sensors, hill-start assist and tyre pressure monitoring.
Other standard safety equipment includes six airbags (dual front, side and curtain), electronic stability and traction control systems, anti-lock brakes (ABS) and brake assist, among others.
That said, high-speed AEB, lane-keep assist and rear cross-traffic alert are among the notable exclusions.
Neither ANCAP nor its European sibling, Euro NCAP, have awarded the 4 Series a safety rating yet.
BMW 4 series7/10
As with all BMW models, the 4 Series comes with a three-year/unlimited-kilometre warranty with three years of roadside assistance, both of which are two years short of the premium standard now set by Mercedes-Benz.
The 440i coupe’s service intervals are every 12 months or 15,000km, whichever comes first. Owners can opt for a $1650 five-year/80,000km capped-price servicing plan, which is well-priced.
