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.

Lexus RC
It's 2019 and the Lexus RC has been with us for four years which means it's time for a mid(ish)-life update. A glance at the specifications and tech details for its very low-key, late 2018 arrival suggests not much has changed. And let's be fair, it hasn't.
The mild refresh has brought a few changes in spec (in the right direction), price (the wrong direction, but few things are free in this life), and styling (you be the judge).

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.
Lexus RC7/10
The RC's time on my drive was preceded by a cheaper, V8-powered Mustang, so it was fascinating to compare the Japanese approach to the American. They're not really competitors, obviously, but the Lexus' ability to cosset the driver while still showing a good turn of speed was an interesting counterpoint.
The 2019 RC350 isn't a step-change - if you want one of those, double your money and get the delightfully nutty RC F - but the changes inside, outside and underneath will certainly please the fans even if it doesn't bring in new ones in huge numbers.
Does anyone still even notice luxury coupes? If you do, is Lexus even on the radar?
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.
Lexus RC7/10
As a whole, I've always thought the RC to be handsome, but the headlights - as on the IS - always made me wince a bit. There's too much going on, which is weird because the rest of the car is very easy on the eye.
As is common with a mid-life facelift, the work all happens at the front and rear. There's a revised bumper, tweaked mesh pattern in the spindle grille, and a much better looking set of headlights - with much cooler LED daytime running lights and headlights. They're still a bit much, but they're not jarring.
The rear is a little cleaner but I reckon it didn't need much work. Along with new wing mirrors from the gorgeous LC coupe and new wheel designs, it's a subtle update, but a good one.
Inside is little-changed, which is good and bad. A new brushed-aluminium dash inlay, a new (naff) analogue clock, and not a huge amount else. The switchgear has a lovely damped feel, nothing clicks or snaps and it really is very serene indeed. Few cars can match a Lexus interior for feel and touch.
Some of the design decisions are confusing, though. A rotary dial to change driving modes looks more like it should be used to control the media system, and the media system's touchpad is really annoying.
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.
Lexus RC6/10
As ever, a sports coupe is the not the place to consider starting your DIY career, but front seat passengers luxuriate with plenty of space. A good-sized glove box joins two cupholders in the centre console which also has a decent-sized bin for hiding things, as well as a sensible place to put your phone (no wireless charging, sadly).
Rear seat passengers have very little space for their limbs or heads but at least the seats are comfortable. Two more cupholders back there, but really, nobody will use them.
The boot is a very useful 423 litres.
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.
Lexus RC8/10
While you can have an RC300 in the mid-sixties, the F Sport starts at $77,529, $200 extra than before. On the face of it, it doesn't look like amazing value, but get a Euro competitor and you'll be paying more.
You get 19-inch alloys, a 17-speaker stereo, four-wheel steering, dual-zone climate control, reversing camera, front and rear parking sensors, active cruise control, auto LED headlights, auto wipers, sat nav, electric heated and ventilated front seats, leather everywhere, a limited-slip diff, variable ratio steering, adaptive dampers, keyless entry and start, and an improved safety package.
The 17-speaker stereo is a treat but the media system is not; controlled from the console by a touchpad, it's hard to use and a pain to navigate. It has Bluetooth and USB connectivity with terrific sound, but it requires patience to operate - which includes the time to get the required qualifications (okay, slight exaggeration). And there is no Apple CarPlay or Android Auto to take the edge off. Pity.
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.
Lexus RC7/10
The RC350 packs Lexus' creamy 3.5-litre, naturally aspirated V6, a step up from the RC300's turbo four-cylinder. Power remains at 232kW/380Nm, driving the rear wheels through an eight-speed torque-converted automatic.
The RC350 cracks the 0-100km/h sprint in 6.3 seconds, which isn't bad considering it's a hefty beast at over 1700kg.
The RC300's turbo four spins up 180kW and an impressive 350Nm if you're keen to save a few dollars upfront and on running costs.
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.
Lexus RC6/10
Lexus says the 350 will manage 9.1L/100km on the combined cycle but I scored a rather less convincing 12.8L/100km. Again, that's probably not bad considering its weight. The tricky dash display had me thinking it was an amazing 7.8L/100km, but it was km/L...
There is no stop-start, cylinder-on-demand or battery regen tech to save fuel - features its European rivals all have at least one of.
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.
Lexus RC8/10
As it has ever been, the RC350 is one smooth, smooth ride. Even the way the doors open is relaxing: swinging wide open like the hinges are made of butter, (except butter that doesn't melt or sag). Look, I'm trying to avoid saying smooth again.
Engine start-up is barely audible and while pottering about the engine remains just as subdued. It's up to the digital dashboard, with its instruments clustered into a single dial with a digital speedo, to let you know what's going on. Few cars outside of the Lexus stable are this relaxing to drive.
What I don't remember from the last time I drove an RC was all-wheel steering. Either I wasn't paying attention or Lexus snuck it in - but it really makes a difference. It's not as aggressive as, say, the bonkers RC F or Renault Sport Megane, it's just there to help bring the heavy car around. It also seems better sorted than the same system in the bigger LC500. And the steering's variable rack works well with it as a partner, too.
The RC's adaptive suspension is so good at what it does. It never over-tightens the suspension but does make a difference in Sport+. It's not really in the 350's nature to take it out for a good thrashing, but it's certainly capable - if held back a little by its portly kerb weight and soft brake pedal feel.
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).
Lexus RC7/10
The RC comes with eight airbags (including knee bags), ABS, stability and traction controls, active bonnet, lane departure warning, blind-spot monitoring, rear cross traffic alert, forward AEB and forward collision warning.
There are two top-tether restraints and two ISOFIX fittings in the back.
ANCAP has not tested the RC but it scored a 'Good' rating from the US IIHS test regime.
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.
Lexus RC7/10
Unlike parent company Toyota, Lexus offers a four-year/100,000km warranty. Also unlike Toyota, you don't get an absurdly cheap deal on servicing, and there's with no capped-price regime. Lexus wants to see your car every 12 months or 15,000km.
To soften the blow of no capped-price servicing, Lexus will either give you a loan car or, even better, come and fetch your car from you before returning it vacuumed, washed, and serviced.
You also get a fairly comprehensive four years of roadside assist and a few other perks.
