Alfa Romeo 4C vs Mercedes-Benz C63

What's the difference?

People might wonder if there’s a reason to buy an Alfa Romeo 4C. It has some great dollar-for-dollar competitors - the Alpine A110 does most of the things the Alfa does, but in a more polished way. And then there’s the Porsche 718 Cayman, which is a considerably more, well, considered option.

But there is no doubt the 4C stands alone, a sort-of cut-price alternative to a Maserati or Ferrari, and nearly as rare to spot on the road as those cars, too. And just like the rollercoaster at Luna Park, it’s the sort of car that’ll leave you wanting another go.

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.

Slap a Ferrari badge on it, and people would think it was the real deal - a pint-sized performance hustler, with all the right angles to get plenty of glances.

In fact, I had dozens of punters nod, wave, mount ‘nice car mate’ and even a few rubber-neck moments - you know, when you drive past and someone on the footpath can’t help but forget they’re walking, and they stare so hard they might well collide with the upcoming lamp-post. 

It really is a head-turner. So why does it only get an 8/10? Well, there are some elements of the design that make it less user-friendly than some of its rivals.

For instance, the step-in to the cabin is enormous, because the carbon-fibre tub sills are huge. And the cabin itself is pretty tight, especially for taller people. An Alpine A110 or Porsche Boxster are much more amenable for day-to-day driving… but hey, the 4C is markedly better than, say, a Lotus Elise for ingress and egress.

Also, as smart as it still looks, there are elements of Alfa Romeo design that have moved on since the 4C launched back in 2015. The headlights are the bit that I dislike most - I had a real thing for the spider-eyes lights of the launch edition model.

But even if it isn’t unmistakably Alfa Romeo, it’s unmistakably a 4C. 

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.

You can’t get into a car this small and expect a lot of space.

The dimensions of the 4C are tiny - it’s just 3989mm long, 1868mm wide and only 1185mm tall, and as you can see from the pictures, it’s a squat little thing. The Spider’s removable roof could be great for you if you’re tall.

I’m six-feet tall (182cm) and I found it to be cocoon-like in the cabin. You feel almost as though you’re tying yourself to the tub of the car when you get into the driver’s seat. And getting in and out? Just make sure you do some stretches beforehand. It’s not as bad as a Lotus for ingress and egress, but it’s still hard to look good clambering in and out of. 

The cabin is a cramped space. There’s limited head room and leg room, and while there is reach and rake adjustment for the steering wheel, the seat only has manual slide and backrest movement - no lumbar adjust, no height adjust… almost like a racing bucket. They’re hard like a race seat, too. 

The ergonomics aren’t terrific - the controls for the air-con are hard to see at a glance, the buttons for the gear select take some learning, and the two centrally-mounted cup holders (one for your double-shot mocha latte, the other for a hazelnut piccolo) are inconveniently positioned exactly where you might want to put your elbow. 

The media system is rubbish. It’d be the first thing to go, if I bought one of these, and in its place would be an aftermarket touchscreen which would: a) actually let you pair to Bluetooth; b) look like it was from sometime after 2004; and c) be more fitting for a car of this price tag. I’d upgrade the speakers, too, because they’re poor. But I can totally understand if those things don’t matter, because it’s the engine you want to hear.

The materials - aside from the red leather seats - aren’t great. The plastics used are similar in look and feel to what you find in second-hand Fiats, but the sheer volume of exposed carbon-fibre does help you forget those details. And the leather pull straps to close the doors are nice, too. 

The visibility from the driver’s seat is decent - for this type of car. It’s low, and the rear window is small, so you can’t expect to see everything around you at all times, but the mirrors are good and the forward vision is excellent.

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.

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.

The Alfa Romeo 4C is powered by a 1.7-litre turbocharged petrol four-cylinder engine, which produces 177kW of power at 6000rpm and 350Nm of torque from 2200-4250rpm. 

The motor is mounted amidships, and it is rear-wheel drive. It uses a six-speed dual-clutch (TCT) automatic with launch control. 

Alfa Romeo claims a 0-100km/h time of 4.5 seconds, which makes it one of the quickest cars at this price point. 

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. 

Claimed fuel consumption for the Alfa Romeo 4C Spider is rated at 6.9 litres per 100 kilometres, so it’s no miser.

But, impressively, I saw real-world fuel economy of 8.1L/100km, over a loop that included urban, highway and ‘spirited’ driving on twisty roads.

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.

I said that it’s like a rollercoaster, and it really, truly is. The air doesn’t quite rush through your hair as much, sure - but with the roof off, the windows down and the speedometer constantly edging towards licence suspension, it’s a real hoot of an experience.

It just feels so tight - the carbon-fibre monocoque chassis is rigid and super stiff. You hit a cats-eye and its all so sensitive, you could mistake it for having hit an actual cat. 

Alfa Romeo’s DNA drive modes - the letters stand for Dynamic, Natural, All Weather - is one of those proper examples of this type of system done well. There’s a marked difference between how these different settings operate, where some other drive modes out there are more sedate in their adjustments. There’s a fourth mode - Alfa Race - which I didn’t dare sample on public roads. Dynamic was enough to test my mettle. 

The steering in Natural mode is lovely - there’s great weighting and feedback, super direct and incredibly in touch with the surface below you, and the engine isn’t quite as zesty, but still offers tremendous response on the move. 

It’ll be a difficult choice between this and Alpine A110 and a Porsche Cayman

The ride is firm but composed and compliant in any of the drive modes, and it doesn’t have adaptive suspension. It is a stiffer suspension setup, and though the damping doesn’t change in Dynamic mode, if the surface is anything but perfect you will tram-track and twitch all over the place, because the steering feels even more dialled in. 

In Dynamic mode the engine offers amazing response when you’re at pace, building speed incredibly and before you know it, you’re in licence loss zone.

The brake pedal requires some firm footwork - just like in a race car - but it pulls up strongly when you need it to. You’ve just gotta get used to the pedal feel. 

The transmission is a good thing at speed in manual mode. It won’t overrule you if you want to find the redline, and it sounds tremendous. The exhaust is exhilarating!

With roof on and windows up there’s very noticeable noise intrusion - lots of tyre roar and engine noise. But remove the roof and drop the windows and you get the full effect of the drive experience - you’ll even get some "sut-tu-tu” wastegate flutter. It doesn’t even matter that much that the stereo system is so rubbish.

At normal speeds in normal driving you do need to be considerate of the powertrain because it is finnicky and slow to react at times. There’s notable lag if you’re gentle on the throttle, both from engine and transmission, and the fact peak torque doesn’t come on song until 2200rpm means there’s lag to contend with. 

It’ll be a difficult choice between this and Alpine A110 and a Porsche Cayman – each of these vehicles has a very different character. But for me, this is the most go-kart like and it is, undeniably incredibly involving to drive.

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.

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).

If you’re hoping that a ‘simple’ car like the 4C will mean low ownership costs, you might be disappointed in this section.

The Alfa Romeo website service calculator suggests that over 60 months or 75,000km (with service intervals set every 12 months/15,000km), you will have to fork out $6625 total. For a breakdown, the services cost $895, $1445, $895, $2495, $895.

I mean, that’s what you get when you buy an Italian sports car, I suppose. But consider you can get a Jaguar F-Type with five years of free servicing, and the Alfa looks like a rip-off. 

The Alfa does, however, come with a three-year/150,000km warranty plan, which includes the same cover for roadside assist.

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.
