Summary
BMW M440I
When BMW’s first-generation 4 Series landed in 2013, it looked and drove like little more than a 3 Series sedan minus the two rear doors, and that’s because it was.
For the second-generation version though, BMW have decided to try its best to differentiate the 4 from the 3 Series, adding a unique front end and slight mechanical tweaks.
Sure, the looks might not be to everyone’s taste, but surely BMW’s renowned driver-focused dynamics will be enough for the 4 Series to carve out its niche in the premium sports coupe space … right?

Mercedes-AMG C63
If you know the Mercedes-AMG C 63 S, you know it’s a hardcore V8 thumper with little in the way of bashfulness. It’s a brawler. A beast.
Now there’s an even more eye-catching AMG C 63 S Coupe, which we’re testing here. It’s the Aero Edition - a collector’s version of the current-generation C 63 S Coupe with a bit more visual bling that also helps it stick to the road better.
It is a local area special edition, with only 63 examples to be sold across Australia and New Zealand. And if the rumours are true, the next-generation will see the V8 engine in danger of being axed in favour of a hybrid, high-performance four-cylinder version. Say it ain’t so!
Well, if the CarsGuide crystal ball turns out to be right, maybe one of these C 63 S Aero Editions is worth getting in your garage quick-smart. Or is it? Let’s go through the criteria and see how it stacks up.

Verdict
BMW M440I8.3/10
BMW has once again delivered a supremely enjoyable sports car with its new 2021 4 Series.
Sure, it might have love-it or hate-it styling, but those that dismiss the 4 Series based solely on looks are missing out on a wonderful driving experience.
With the base 420i offering all the style in a relatively affordable pricetag, while the all-wheel-drive grip of the M440i adds extra assurance at a more premium price, BMW's new 4 Series should cater to anyone looking for a premium sports coupe.
Mercedes-AMG C637.8/10
The Mercedes-AMG C 63 S Aero Edition is an absolute beast of a car, but it comes at a pretty hefty price. Yes you get a lot of performance, and the fact there are only 63 examples being made for Australia and New Zealand could be enough to get you to sign on the line. For me, though, if I was after a C 63, it’d have to be a wagon. It doesn’t need an Aero pack to look better.
Design
BMW M440I10/10
Let’s get this out of the way. The 2021 BMW 4 Series is not an ugly car, despite what you may think from the press photos found online.
Is it to everyone’s tastes? Of course not, but I find the gaudy, in-your-face gold-on-black that is Versace’s signature styling a little gross … so your milage will definitely vary on the 4 Series like mine does with high-end fashion.
In person, that grille is nowhere near as overwhelming as pictures may have led you to believe, and blends in very nicely with the aggressive and muscular front end of the 4 Series.
In profile, the high shoulder line and slim glasshouse add to the sportiness, as does the sloping roofline and butch rear haunches.
The rear though, is arguably the 4 Series best exterior angle, as the pinched bumper, wraparound tail-lights, large exhaust outlets and subtle rear diffuser combine well for a properly sporty and premium look.
All Australian-spec cars come with the M Sport package, meaning a full bodykit, and 19-inch wheels to make even the boggo 420i look aggressive on the road.
Does it work? Well if it wasn’t wearing a BMW badge then it might not get away with this ostentatious styling, but being a big premium player, we think the 4 Series gets away with being as brash and in-your-face as it is.
We actually love that BMW has taken a risk with the 4 Series’ aesthetics and is willing to push the envelope because, after all, it could have just looked like the 3 Series sans-two doors, and that’s just a bit too safe, isn’t it?
Inside, the 4 Series is familiar BMW territory, which means a thick-rimmed steering wheel, glossy shifter and brushed metal accents, as well as high-quality materials throughout.
The dashboard-integrated multimedia system is a particularly nice touch, as are the metal accents that separate the lower and upper halves of the cabin.
So, is there anything interesting about the design? Absolutely. It’s got the internet talking more than usual and will no doubt draw the eye of those wanting to stand out from the often-samey crowd of German sports cars.
Mercedes-AMG C638/10
I’ve never been the biggest fan of the current C-Class Coupe’s styling. To me, it has always looked a little droopy, a little melted at the back.
I have to say, the Aero Edition has changed my opinion somewhat, as the new graphic elements help lift it up a bit, visually raising its rear up like a stretching cat, tail in the air. I’m still not 100 per cent on it, but to my eye it’s better.
The carbon-fibre trim elements that have been added to the exterior certainly add some menace to the look, too, and I simply can’t help but constantly notice out of the corner of my eye the AMG pressing in the staggered, dished rims. At a glimpse, from a distance, it looks like rim damage, but thankfully it’s not!
The staggered set-up does really add some width and mongrel to the look, as if it needed more, with its open maw lower bumper air dam, and the signature 'Panamericana' grille treatment which looks like an evil character out of a movie. If you know the one I’m talking about, let me know in the comments.
As much as the look matters when it’s parked in your driveway, it’s the cabin that arguably matters more, right? That’s where you spend your time, after all. Check out the interior images to see if you think it lives up to the exterior look.
Practicality
BMW M440I8/10
Measuring 4768mm long, 1842mm wide, 1383mm tall and with a 2851mm wheelbase, the 2021 BMW 4 Series certainly looks commanding on the road, and the generous proportions do well for interior space too.
Of note though, the M440i is slightly longer (4770mm), wider (1852mm) and taller (1393mm) than the 420i and 430i, but the slight variance doesn’t translate to any perceivable difference in practicality.
Up front, there is plenty of space for driver and passenger, with a wide array of seat adjustability offering nearly the perfect position for nearly everyone regardless of shape or size.
Storage options include a generous door pocket with separate bottle holder, large central storage cubby, generous glove box, and two cupholders sited between the shifter and climate controls.
We love that the wireless smartphone charger is tucked well away just ahead of the cupholders, meaning you don’t have to worry about keys or loose change scratching up your screen, and it doesn’t eat into any of the other storage options around the cabin.
Being a coupe, you wouldn’t expect heaps of room in the second row, and the BMW 4 Series certainly doesn’t defy expectations in this regard.
Adult passengers can get in the back easy enough, thanks to auto-folding front seats, but once there, head- and shoulder-room can be a bit tight, while legroom is dependent on the height of front passengers.
We’ve certainly been in worse back seats though, and the deeply recessed seats help alleviate some of the headroom issues, but its not a space for the claustrophobic.
Open the boot and the 4 Series will swallow up to 440 litres of volume and, thanks to the wide space, can easily accommodate a set of golf clubs or weekend luggage for two.
The second row is divided 40:20:40, so you can fold down the middle to transport skis (or timber from Bunnings) while still ferrying four.
Folding the rear seats down will increase your cargo volume, but the aperture between the boot and cabin is quite small, so you might want to keep that in mind before heading to Ikea.
Mercedes-AMG C637/10
No two-door coupe is going to offer you the space and comfort of a sedan or wagon, that’s just a fact. But that only matters if you plan to actually use the rear seats. If you don’t, then the Coupe version of the C 63 S might be perfect for you.
Even so, I managed to (only just) squeeze myself between the seat and the door opening to slide into the rear row. This won’t be easily achieved by all attempters, especially on the driver’s side.
Let’s just say I probably looked like I was doing something very weird to the driver’s seat as I spider-manned my way in.
The rear space is tight for someone my height (182cm/6’0”) behind their own driving position, with knees hard-up against the seat in front and not much headroom (my noggin’ was brushing the ceiling) or toe space (size 12s don’t fit so well) to speak of.
It’s certainly a selfish car. Or maybe it’d be fine for smaller kids. There are two spaces in the back, both with ISOFIX child seat anchors and top-tether points.
But there is storage in the back - cupholders and storage caddies either side of the seats, though the storage situation improves in the front zone, with bottle holders in the doors, cupholders between the seats, loose item storage under the media screen and a covered centre armrest bin, too.
The front cabin is a special looking place, with carbon-fibre abounding across the dash and nice trim on the doors. The AMG steering wheel is a sight to behold - it’s a flat-bottomed unit with carbon-fibre and Dinamica (that’s Benz talk for microsuede) trim: perfect for sapping sweat as you manhandle the C63 through the bends.
The seats are AMG Performance sports units up front, and the trim used is reserved for this model specifically: Nappa leather with yellow stripes. There are yellow details elsewhere, including on the rear seats, centre console and dash, and it certainly adds some visual excitement.
Media is controlled by a 10.25-inch display and Mercedes-Benz’s touchpad control system, but there is no touchscreen - rendering the Apple CarPlay and Android Auto smartphone mirroring technology somewhat tedious.
I’ve always had a gripe with screens that don’t allow touch but feature the tech that’s designed to transfer your phone’s screen to the media unit, and I can tell you the longer you spend twiddling the dial to get where you want to go, the more annoying it becomes.
The Burmester sound system has 13 speakers and is rather good, but I prefer the sound from the standard fit variable sports exhaust. So maybe that quibble with CarPlay isn’t that big a deal.
And if you just want to charge your phone, and there’s a second USB port up front, as well. Note: in non-Aero Edition C 63 models without the carbon-fibre interior pack, you also get Qi wireless phone charging, but it’s deleted from this variant and any model with the carbon pack.
The driver has a 12.3-inch digital info display to show where you are and what the car is up to, and there’s a head-up display as well. Yep, there’s standard sat nav with live traffic updates (and even live fuel price updates) - it’s just a shame the maps still look early 2000s-spec in 2D layout.
Cargo space is okay. The claimed cargo capacity or boot volume is 355 litres (VDA) with the rear seats in place. That’s small for a coupe of this size, and the shape of the boot (with a hump behind the rear seat) isn’t great as things do move around quite a bit.
But, thankfully, Mercedes has included its clever foldable storage box system under the boot floor - it goes where you might usually expect a spare wheel, but there isn’t one in this car. Instead you get Mercedes’ 'Tirefit' repair kit with an electric pump.
Price and features
BMW M440I9/10
BMW’s new 4 Series range is available in three flavours, kicking off with the 420i for $70,900 before on-road costs, which is powered by a 2.0-litre turbo-petrol engine (more on that below).
Standard equipment includes sport seats, LED headlights, a 12.3-inch digital instrument cluster, push-button start, automatic wipers, Alcantara/Sensetec (vinyl-like) interior trim, three-zone climate control and 10-speaker sound system, but it’s the inclusion of an M Sport package and 19-inch wheels that really elevate the look of the new 4 Series to a real sporty model.
The latter two were options in the previous generation, but so many customers (we’re told close to 90%) opted for the sportier looks that BMW just decided to bundle them into the asking price.
The 420i also comes fitted with a 10.25-inch touchscreen multimedia system that includes digital radio, satellite navigation, wireless smartphone charger, and wireless Apple CarPlay AND Android Auto (finally some love for Samsung owners!).
It’s remarkable then, that the new 420i is actually almost $4100 cheaper than the model it replaces, while also boasting more equipment, safety and torque.
Stepping up to the 430i increases pricing to $88,900 ($6400 pricier than before), while also adding more equipment such as adaptive dampers, keyless entry, surround-view camera, M Sport brakes, leather interior and active cruise control.
Outputs from the 2.0-litre turbo-petrol engine are also increased in the 430i (again, more below).
The current king of the 4 Series range until the M4 lands early next year is the M440i, priced at $116,900, but includes a 3.0-litre inline six-cylinder engine and all-wheel-drive grip.
On the outside, the M440i can be distinguished by the standard inclusion of BMW’s Laserlight technology, sunroof and heated front seats, as well as ‘Cerium Grey’ colouring for the kidney grille, tailpipe shrouds and side-view mirrors.
Being a German model, there is (of course) a smattering of options available – including remote engine start and a heated steering wheel – but none jump out as crucial or ‘must have’ in any way.
We appreciate that the base 4 Series looks largely the same as its more expensive siblings, while also offering all the key equipment you’d want out of a premium sports coupe in 2020.
Mercedes-AMG C637/10
Look, I’m not likely to ever be in the position to say that a car that costs $188,600 plus on-road costs is “good value”, but to be honest, if you’re in that position, you’ll be getting plenty of car for your cash.
The Carbon Edition of the C 63 S Coupe adds $17,200 over the standard version of the high-performance two-door, but it adds a bunch of extras to help justify its price. A car like this is always going to be seen by some as a profligate purchase, right? You need to be able to justify spending an extra MG3’s worth of cash on this Edition.
The noticeable exterior bits include an AMG Performance rear spoiler, a model specific front lip, rear diffuser, and side facings for the rear apron air vents. Carbon-fibre is used in the front apron A-wing, the side sill inserts, rear diffuser insert, rear spoiler and the side mirror casings.
There’s more carbon-fibre inside the cabin, which we’ll cover off in the interior section. Other additions over the standard C 63 S Coupe include ceramic composite front brakes (402mm six-piston) and 360mm single-piston rear brakes, and there are “ultra-lightweight” AMG forged 'Matt Black' alloy wheels with 19-inch rims at the front and 20s at the rear.
And in nice news, the car you see here has no optional extras fitted at all. The colour is 'Iridium Silver', one of only two options for this limited run model (the other available hue is Polar White, and both come at no extra cost).
Standard inclusions comprise leather interior trim, heated and electric adjustable front seats, dual-zone climate control, a 10.25-inch media screen with sat nav and smartphone mirroring, DAB radio, 13-speaker Burmester sound system, 12.3-inch digital driver info display, head-up display (HUD), ambient lighting, and performance items like active dynamic engine mounts, an adaptive AMG performance exhaust, a rear differential lock, and adaptive sports suspension.
Plus there’s a full-spec safety offering which we’ll cover in the section below.
Thinking about what cars compete with this one? There’s the Audi RS 5 Coupe (from $150,900), the Lexus RC F (from $136,636), and the BMW M4 Competition (from $167,829). So the C 63 S - which is already expensive comparatively - looks positively pricey in Aero Edition spec.
Under the bonnet
BMW M440I7/10
Both the entry-level and mid-tier 4 Series variants (420i and 430i respectively) are powered by a 2.0-litre turbocharged petrol engine.
Under the bonnet of the 420i, the engine produces 135kW/300Nm, while the 430i ups the ante to 190kW/400Nm.
The flagship (at launch) M440i meanwhile, scores a 3.0-litre turbo-petrol inline six delivering 285kW/500Nm.
All three engines are paired with an eight-speed automatic transmission, with no manual option available on any grade.
The 420i and 430i send drive to the rear wheels, resulting in a zero to 100km/h sprint time of 7.5 and 5.8 seconds respectively, while the all-wheel-drive M440i needs just 4.5s.
Stacked up against its German rivals, the 4 Series offers a decent engine line-up, but doesn’t excel at any level compared to the Audi A5 and Mercedes-Benz C-Class coupe.
Mercedes-AMG C639/10
Open the shapely bonnet of the C 63 S and you’ll find a hand-assembled horsepower-monster engine with a printed name plaque to prove it.
The 4.0-litre twin-turbo V8 produces 375kW of power at 6250rpm, and 700Nm of torque from 2000-4500rpm. It runs a standard-fit nine-speed 'Speedshift MCT' (multi-clutch transmission) automatic, and it’s rear-wheel drive. And yes, that means it likes to boogie.
The claimed 0-100km/h time is just 3.9 seconds, and top speed is apparently pegged at 250km/h. Yeesh.
The name on the “Handcrafted by” plaque on this particular engine? Hat tip to you, Julian Rembold. This is quite a piece of work.
Efficiency
BMW M440I8/10
Officially, the 420i will sip 6.4 litres per 100km, while the 430i is slightly thirstier at 6.6L/100km.
Both aforementioned 4 Series variants will need 95 RON at the bowser.
The heavier and more potent M440i needs 7.8L/100km, while also using the more expensive 98 RON fuel.
We only drove through Melbourne country roads in our brief time with all three grades of the 4 Series and could not ascertain a reliable fuel economy figure.
Our driving did not cover an extended freeway journey or any inner-city driving, so check back to see if the quoted figures hold up to scrutiny once we get more time with the car.
Mercedes-AMG C636/10
High numbers are what AMGs are about. Sadly that’s the case not only for performance outputs but also fuel consumption.
The official combined cycle fuel use claim for the C 63 S Coupe is 10.3 litres per 100 kilometres, and you need to fill it with 98RON premium unleaded fuel, too.
On test? Well, across a mix of different driving - urban, highway, back road and spirited stints - I saw an 'at the pump' return of 12.2L/100km, while the digital readout stated 12.0L/100km.
Given the performance on offer, and how much I took advantage of it during my week with the car, that’s not bad…
Fuel tank capacity is 66 litres. So go easy if you know there won’t be a fuel stop for a while.
Driving
BMW M440I9/10
Anything wearing a BMW badge promises a fun and engaging drive, after all the brand’s tagline used to be the ‘ultimate driving machine’, which is exacerbated in a sporty two-door.
Luckily then, the 4 Series delivers the goods and is a thoroughly enjoyable drive in all three grades.
Taking the already brilliant new-generation 3 Series as a base, BMW has made the 4 Series lower, and added additional stiffening in the front and rear for a taught and agile handling machine.
The rear track is also increased, while the front wheels have more negative camber to help with mid-corner grip.
Though the 420i and 430i might not draw any headlines, they 2.0-litre turbo-petrol pair are fun to steer and precise with their inputs.
The 420i especially doesn’t have the punch to match its aggressive looks, but is perfectly capable at slower speeds and still a delight to tip in a corner.
The 430i meanwhile, delivers more thrills thanks to its more potent engine, but it can get a bit trashy higher in the rev range.
However, the pick of the bunch for us the M440i, not only for its extra spicy engine, but also the assurance of all-wheel drive.
Now it might be sacrilege to some to not have a rear-drive BMW, but the rear-biased xDrive system in the M440i is wonderfully tuned to deliver the same sort of natural driving characteristic of a two-wheel-drive model.
Undoubtedly the near-perfect weight distribution helps with this, while the wonderfully low driving position means the whole car feels like it pivots around the driver when turning the wheel.
The M Sport differential in the rear is also great at propelling out you out of the bends, while the adaptive suspension also has great variability between comfort and sport settings.
If we had any criticism with the driving experience? We’d have liked a bit more aural theatre, but BMW have to save the louder pops and crackles for the full-fat M4, right?
A big caveat here though is that we have yet to experience the new 4 Series in a suburban setting, with our launch route taking us directly to some twisty country roads.
We also never got to drive the 4 Series in a freeway setting, meaning all of the driving was done in twisty country roads where you would expect a BMW to excel.
Mercedes-AMG C639/10
Just one word sprang to my mind when it comes to accurately describing the performance on offer from this car. The word is ‘brutal’.
Smash the accelerator and the power and torque on offer is enough to make your eyes feel like they’re not doing the right thing anymore. You get pushed back in your seat with a surge, and your ears are also rewarded with one of the best soundtracks in the automotive world.
The engine builds pace with enormous intent, and the sound that comes from under the bonnet and out the back through the exhausts is addictive.
Yes, there is an active exhaust button which you have to press to make sure that you hear all that noise if you’re running around in 'Comfort' mode, and during my time with the car it was active the whole time.
I had some questions from neighbours over the week that I had this car about whether it was actually nice to live with on a day-to-day basis. And the answer is yes, if you put it in comfort mode it’s surprisingly amenable.
The ride is really well sorted at pace despite having a bit of that trademark low-speed wobble that seems to afflict Mercedes products from A-Class through to the GLE SUV. But it wasn’t bad enough to really bother me, as most of my time was on highways and backroads.
The steering is direct and accurate. The only thing you need to be aware of is that you will lose traction at the rear axle when you put your foot down hard. And for the enthusiast that’s exactly what you want.
I know I want to feel the thing squirm under throttle. It’s a rear-drive V8 coupe, after all. You want to feel like you’re a vein in its bicep muscle; you know, the one you see in a weightlifter’s arms – the one that wiggles around a lot. You want to have that. Right?
On the performance front it is exceptional. Twist the little dial on the wheel to 'Sport' or 'Sport+' (I didn’t sample 'Race' mode as I wasn’t at a racetrack), and everything feels like it’s had a protein shake.
Even so, in that mode it steers brilliantly, there's a nice feel through the wheel, and the ride, while stiff, controls the body brilliantly when you change directions.
The transmission is very good, too. In Comfort mode it can take just a second or two at first to become accustomed to the idea that you want to drive aggressively.
But in Sport mode, or when you select the manual transmission mode using the trigger button on the steering wheel, you will certainly get the most out of the engine. That’s what I did when I was driving it in a ‘spirited’ manner.
If you are just after that high-end Coupe cruiser experience, it’s a relatively quiet car (provided the surface below isn’t the coarsest of coarse-chip bitumen), with enough luxuriousness to make it feel premium as well as sporty. That’s an important thing to consider, especially at this price point.
Safety
BMW M440I7/10
BMW’s 2021 4 Series has not been crash tested by either Euro NCAP or ANCAP, and does not wear an official safety rating.
However, the mechanically related 3 Series sedan was awarded a maximum five-star rating when it was examined in October 2019, but do keep in mind that the child occupant protection scores could vary wildly due to the 4 Series’ coupe shape.
The 3 Series scored 97 per cent for the adult occupant protection test, and 87 per cent for the child occupant exam. Meanwhile, the vulnerable road user protection and safety assist tests yielded an 87 and 77 per cent result respectively.
As standard, the 4 Series is equipped with autonomous emergency braking (AEB), forward collision warning, lane departure warning, rear cross-traffic alert, reversing camera, and front and rear parking sensors.
Mercedes-AMG C638/10
There is no applicable ANCAP crash test rating for the Mercedes C-Class Coupe, nor is there one for the C 63 specification. But when it was tested back 2014, the sedan scored five stars - as you’d expect.
It is comprehensively equipped in terms of safety technology, including auto emergency braking (AEB) with pedestrian and cyclist detection (from 7.0km/h to 70km/h) and it’s active for cars from 7.0km/h to 250km/h.
Plus there’s lane departure warning and active lane keeping assistance (from 60km/h to 200km/h), blind spot monitoring with 'Active Blind Spot Assist' that will stop you from veering into oncoming traffic, front and rear cross traffic alert, and adaptive cruise control (Distronic) with traffic jam assist.
The C 63 also features 'Route Based Speed Adaptation', which can adjust your speed based on where the car thinks you are on the map. Just note - if you’re driving through new tunnels that haven’t been flashed to your car’s nav (as happened to me in Sydney during my testing week) - then you could find the car dramatically braking for surface-level intersections. You can switch the system off, thankfully.
There are nine airbags fitted, and while you mightn’t use the rear seats much there are ISOFIX and top tether points for both positions (yes, only two).
Ownership
BMW M440I8/10
Like all new BMW models, the 4 Series comes with a three-year/unlimited kilometre warranty.
However, the benchmark for premium brands belongs to Mercedes-Benz, who offer a five-year/unlimited kilometre warranty, while Genesis matches the time period but limits travel to 100,000km.
Scheduled servicing for the 4 Series occurs every 12 months or 16,000km.
At the time of purchase, BMW offers a five-year/80,000 ‘basic’ service package that covers scheduled changing engine oil, filter, spark plugs and brake fluids.
This package costs $1650, which works out to be a very reasonable $330 per service.
A more thorough ‘plus’ plan is also available for $4500 that also covers brake pads/discs, clutch and windscreen wiper replacements over the same five-year/80,000km period.
Mercedes-AMG C638/10
Mercedes-Benz is among the minority of luxury brands now offering a five-year/unlimited kilometre warranty plan - most still have three-year cover. So that’s a tick.
And the service intervals are pegged at 12 months/20,000km. Another tick.
Plus you can either pre-pay your service plan in three-year ($3800), four-year ($6000) or five-year ($6550) plans - roll it into the finance package, and it won’t hurt quite as much.
According to Mercedes, the three-year coverage option makes for a $900 discount over pay-as-you-go servicing.
Roadside assistance covers the five-year new car warranty period, too. So Mercedes seemingly takes good care of its customers. But if you have any concerns or questions over reliability, problems, issues or complaints about the C 63, check out our AMG C 63 problems page.
