Summary
Mercedes-Benz 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.

Porsche 718
Porsche has taken its entry-grade 718 Cayman and created a special Style Edition which adds more features and some nice aesthetic touches to what is one of the best and relatively affordable, prestige sports cars on the planet.
What makes this car even more special is knowing Porsche will adopt an electric powertrain for the next Cayman. Yup, this is one of the final Caymans to have a combustion engine. Talk about a limited edition.
So what’s not to love? Well, you’ll have to read on to find out because although the 718 Cayman Style Edition is wonderful in so many ways, there are some sides to it you need to know about before diving into the ownership experience.

Verdict
Mercedes-Benz 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.
Porsche 7187.3/10
The 718 Cayman Style Edition only costs a bit more than the entry-grade Cayman it's based on, but opens up more special colours and contrasting features from the wheels to decals, even leather upholstery. The value is good, the look is enhanced and the car remains superb to drive on the right roads.
Living with a Cayman daily is ‘do-able’ but you’ll have to be understanding given it's not the most user-friendly car to drive, and then there’s the low-level safety tech.
But in return, you’ll own one of the best and relatively affordable prestige sports cars ever made and one of the last of the combustion-powered Porsche Caymans.
Design
Mercedes-Benz 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.
Porsche 7188/10
The 718 Cayman is often labelled as the 'junior 911' but that downplays its status as an outstanding sports car in its own right.
It’s not a smaller version of the 911, at all, but it is smaller than a 911. Not by much, though. The Cayman is 140mm shorter in length than the 911 at 4379mm end-to-end. Interestingly, the Cayman has a longer wheelbase at 2475mm and is taller at 1295mm.
The 718 Cayman is beginning to date in its design with this generation of the sports car arriving eight years ago. From the outside it’s holding up well in terms of styling , but inside it feels very 2016 with the small media screen and analogue dials.
It gives me a weird nostalgic feeling I normally only get driving older cars, but in a current model. Which could be why Porsche is jazzing the Cayman up with this Style Edition.
The Style Edition enhances the look of the entry-grade Cayman with 20-inch 718 'Spyder' wheels in a high gloss black or white finish, and there’s a choice of six special colours ranging from the Crayon hue our car wore to 'Ruby Star Neo', 'Shark Blue', 'Carmine Red' and 'Arctic Grey'.
The Style Edition also adds black sport tailpipes, full-colour Porsche crests on the wheel hub covers, a black leather interior with contrasting Crayon stitching, Porsche crest embossed headrests, illuminated door sills and floor mats with Crayon contrast stitching.
Buyers can also choose a 'Contrast Package' in black or white which adds Porsche lettering to the side of the car and a strip to the bonnet.
Practicality
Mercedes-Benz 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.
Porsche 7187/10
The 718 Cayman doesn’t have back seats - it's a two-seater sports car. Cabin storage is almost non-existent but is saved by a glove box and pull-out door pockets which are bigger than they look.
Surprisingly, there are three cupholders - two which pop out of the dashboard above the glove box and another in the small centre console bin.
Cargo space isn’t bad for a two-seater sports car with 184-litre rear boot and a front boot with a 150-litre capacity. That’s roughly one nine-year old child as you can see from the photos. My son wanted to sit in there, which I agreed to, but I said no when he asked me to shut the bonnet.
Price and features
Mercedes-Benz 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.
Porsche 7188/10
The 718 Cayman Style Edition lists for $136,700 and this is for the manual version, the auto is $5340 more. All up Porsche is asking $4200 more than the entry-grade Cayman it’s based on. In return you’re getting some nice features you won't find on the standard model.
There's the chunky black exhaust tips, the full-coloured crests on the wheel caps and inside is the black leather interior package with embossed headrests, illuminated door sills, and floor mats with 'Crayon'-coloured stitching.
Buyers can also specify one of two Style Edition contrast packages - one in Black and one in White - at no extra cost. Ours had the Black package specified and added the Porsche decals to the side of the car, the stripe on the bonnet and the gloss black 20-inch wheels.
The colour of our car was Crayon which comes as part of the bespoke colour offerings with the Style Edition.
Along with these Style Edition features there are the standard features of the entry-grade Cayman, including LED headlights, proximity unlocking, power adjustable sports seats, media display with sat nav, Apple CarPlay and dual-zone climate control.
If you’ve been driving new cars lately you might be a bit disappointed by the Cayman’s small media display (it’s a 7.0-inch screen which is tiny by today’s standards) there’s also no Android Auto available (just Apple CarPlay) and safety tech is relatively light-on, too. You can read about this further down.
It should be pointed out here that our car was fitted with a dual-clutch automatic transmission and the optional adaptive cruise control ($2320).
Under the bonnet
Mercedes-Benz 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.
Porsche 7188/10
So, under the bonnet of a Cayman is the front boot, but if it’s the engine you’re after you’ll need to go through the rear hatch because this is a mid-engined car.
Getting to the engine means removing several fixtures and covers which begins to feel like you’re dissembling the vehicle and comes with a rising anxiety that it all won’t go back together.
But it all clicks back in. It’s just a slow and tedious process. Fortunately, oil and water can be added by removing the circular covers you can see in the images.
Under the layers of covers, deep down just in front of the rear axle, is the Cayman’s 2.0-litre ‘flat’ four-cylinder turbo-petrol engine which makes 220kW and 380Nm. A seven-speed dual-clutch automatic transmission sends drive to the rear wheels.
It’s not a huge amount of power but the Cayman only weighs 1365kg and so can get from 0-100km/h in 5.1 seconds. Not brutally quick but the way this car handles is what you’ll like.
Oh, and just to be clear, the Style Edition doesn’t bring any extra power or engine changes. The outputs and performance are the same as the entry-grade Cayman.
Efficiency
Mercedes-Benz 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.
Porsche 7187/10
Porsche says that after a combination of open and urban roads the Cayman’s fuel consumption should be 7.0L/100km. My 143km fuel test, taking in country roads and school runs, used 21.8L of petrol and equates to 15.2L/100km. Which means I had about twice as much fun as Porsche did when it recorded its fuel consumption.
The 64-litre tanks means in theory you should be able to travel 914km between fills if you’re conservative with fuel.
Driving
Mercedes-Benz 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.
Porsche 7189/10
The 718 Cayman Style Edition doesn’t come with any performance advantages over the already brilliant entry-grade Cayman it’s based on. And it is brilliant to drive. Several big steps above Audi’s TT, Nissan's Z or Toyota and BMW’s Supra/Z4 'twins under the skin' in terms of handling, steering and engagement.
That said, the Cayman isn’t as easy to drive as any of those cars. The steering is heavy, the accelerator is stiff, the dual-clutch auto transmission feels a bit rough and the turbo lags, then sends in the mumbo a bit too fast and too late. Oh, and and the seats are a tad tight.
But I can overlook all of this because on good winding country roads the Cayman feels like a water drop running down a wall, moving naturally and harmoniously around whatever it encounters.
The day-to-day school runs and grocery getting isn’t quite as poetic, and a Cayman proves challenging in the real world over potholes and in supermarket car parks. You’d have to love the Cayman for better or worse, as many do, to live with it daily. If you can't, there's the Audi TT.
Safety
Mercedes-Benz 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).
Porsche 7185/10
The almost complete lack of standard advanced safety technology on board the Porsche Cayman might be a deal-breaker for you. There’s no AEB (forward or reverse), no cross-traffic alert and no lane keeping assistance. But there is blind-spot warning, front and rear parking sensors and a reversing camera. Adaptive cruise control is a $2320 option.
The 718 Cayman hasn’t been crash tested and therefore doesn’t have an ANCAP rating, but you’ll be pleased to know there are four airbags covering the driver and passenger.
Ownership
Mercedes-Benz 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.
Porsche 7186/10
The Cayman Style Edition is covered by a three-year/unlimited kilometre warranty and servicing is needed every 12 months or 20,000km.
With Porsche, final service costs are determined at the dealer level (in line with variable labour rates by state/territory).
We'd like to see the warranty coverage increased to five years/unlimited kilometres which will bring it in line with more mainstream brands.
