Toyota GR86 vs Mercedes-Benz C63

What's the difference?

If you’re expecting a faster, angrier and more focused version of the original 86, you’re going to be happy with this car. If you’re expecting it to be as fun and chuckable as the first one, you might be upset.

It has a different character, this GR86 - certainly with more GRRRR than ever before - and it still represents a strong sports car option for buyers, even if it is a fair bit more expensive this time around. It'd be hard not to recommend the GTS version to anyone considering it.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel and meals provided.

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.

The GR badges mean a lot, here. Not just because they signify that this is a proper Gazoo Racing product for Series 2, but also because they help you pick it as the Toyota and not the Subaru BRZ.

They are even more closely aligned in terms of exterior design this time around, and while both are good looking sports coupes, I wish more had been done to differentiate the two.

Sure, if you’re paying attention you’ll see the shape of the intake / grille area is different, and it has a different bumper shape to the BRZ, too - and both of them are bloody good looking cars, if you ask me.

The rear is particularly smart, I reckon - a more sporty and sleek appearance than the last one, and even if the tail-lights are somehow familiar, I think it’s a neat rear end. Can’t wait to see who makes the best looking aftermarket rear spoiler for it.

If you’re curious about the size and dimensions of the new GR86 compared to the old one, Toyota says it measures 4265mm (up 25mm) on a 2575mm wheelbase (up 5mm), sits 1310mm tall (down 10mm), and has the same overall width of 1775mm excluding mirrors.

There have been some big design changes in the cabin, though the overall layout is tremendously similar to the last car. It has similar controls for the air-con, a new touchscreen above, and similar layout to the storage, too. 

The interior design is a bit plain, though - the screen is big and colourful, and I’m thankful for that. Because unless you option the GTS with the red carpet, it’s a bit bland in there.

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’re not buying a sports coupe if you value practicality as a primary purchase consideration, but rest assured, the GR86 has a decent level of usability to the interior.

There are bottle holders in the doors, storage sections in front of the gear selector, and a pair of cup holders with a closing lid that doubles as a centre armrest, if you don’t have drinks. Thing is, the one on the car I drove at launch was pretty hard to open with a single press of the button.

The 8.0-inch multimedia touchscreen is straight from Subaru, with Subaru graphics and fonts still included. That’s not necessarily a bad thing, as the screen is colourful and has easy menus and controls, and thankfully there are still knobs and dials for things like volume and tuning.

It has the requisite Apple CarPlay and Android Auto phone mirroring tech, but I had the system lose connection with my iPhone 13 Pro on the launch. (Note: I have a long-term Subaru WRX Sportswagon that drops the phone connection all the time, so it’s a bit annoying to see this characteristic mirrored on other models.)

Below the screen are the ‘they-look-familiar’ air-con controls, with dials for temp and fan. They’re nice and chunky so you can easily locate them when you’re focusing on driving. I like that.

The newly designed folding seat mechanism is supposed to allow you easier access to the back seats, not that you’ll want to be in there if you’re an adult. Or anyone over, say, 10 years old.

I got in there (for scientific research purposes) and found it was, as you’d expect, not very comfortable for someone my size (182cm / 6’0”). My head was at an awkward angle, I had little leg or toe room even with the seat ahead of me pitched way forward, and there’s not much in terms of rear-seat amenities, either.

But, if you have younger children, there are ISOFIX points and top-tether points for both of the rear seat positions.

Boot space is 237 litres - which isn’t enormous. But the opening is wide enough to easily slide suitcases in, and you can fit four wheels and tyres in with the back seat folded down (according to Toyota - and it folds down in a single piece, there’s no split-fold rear seat).

Oh, and the last one used to be available with a spare - this one isn’t. Just a repair kit.

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.

It’s a bigger engine - now a 2.4-litre horizontally-opposed ‘boxer’ four-cylinder petrol unit - and that increase of 20 per cent engine capacity has yielded some good horsepower increases, too. And it has a Subaru badge on the engine cover. Because it’s a Subaru engine.

The new model pushes out 174kW of power (at 7000rpm), which is up from a max output of 152kW on the old model.

It’s the torque figure that’s interesting, though. There’s 250Nm at 3700rpm, which isn’t huge. But Toyota claims there’s 240Nm available from 3500-6500rpm, meaning a long flat torque build-up. The old model had 212Nm for the manual.

Now, both the six-speed manual and six-speed automatic transmission have the same power and torque outputs - in the last gen, the auto was held back by 5kW and 7Nm compared with the max-power manual.

Of course, it’s rear-wheel drive, and has a Torsen limited slip differential in the mix. 

Toyota says the 0-100km/h time for the manual is 6.3 seconds, which is 1.8sec faster than the last manual. The auto’s 0-100 is claimed at 6.8sec.

Wondering about weight? The new one has four different masses to consider: GT manual - 1287kg; GT automatic - 1308kg; GTS manual - 1291kg; GTS automatic - 1312kg. Toyota says the bulk of the additional circa-44kg increase across the board is down to the larger capacity engine.

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. 

Official combined cycle fuel consumption is also a matter of spec-by-spec: GT manual - 9.4L/100km; GT automatic - 8.7L/100km; GTS manual - 9.5L/100km; GTS automatic - 8.8L/100km.

On test, the GTS manual I drove on the road loop at the launch was showing 9.8L/100km on the display after a mix of mostly higher-speed country road testing around Phillip Island and surrounds.

The fuel tank capacity is 50 litres, but keep in mind you’ll need to be fueling up with 98RON premium unleaded. 

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.

Have you ever been cutting veggies for dinner and realised you need to sharpen your knife? And then, once you’ve done it, you realise what the knife is really capable of?

That’s kinda the feeling between the last generation of the Toyota 86 and this new Toyota GR86.  

I loved the old 86. Still do. Would have one in a heartbeat. But this - as the analogy suggests - is a much sharper tool.  

The engine is a big improvement on the old 2.0-litre - it feels considerably more urgent, and it gathers pace without fuss. You can really rely on the torque of the engine more in the new GR86 - that wasn’t so much the case in the last car, which you had to row through the gears more in. Now you can leave it in fourth and allow the engine to do the work, whereas in corners in the old car, you’d probably have elected to downshift to third, maybe second. 

The manual transmission is good, for the most part. It’s easy enough to operate, though the shift action can still feel a little bit notchy (first to second, fifth to sixth in particular in the car I drove). The clutch feel was reasonable, but not stall-proof at low speeds. 

The sound of the engine is a bit more pleasant now, too. It doesn’t have the nasal overtones of the last one - with a deeper, more enjoyable noise. It’s not the best sounding boxer engine, but it’s not the worst, either.

I only had a short amount of time in the GR86 automatic, and it was on the Phillip Island race track. It has paddles, which I appreciate - but the gearbox will overrule you if you try and downshift and haven’t managed to get the engine revs down. Self preservation at the expense of outright fun? Yeah. A bit. A dual-clutch auto would be an interesting development in this car - but it’s not going to happen.

Drivers who live in areas where there are lots of potholes and bumpy sections of road - so, most of Australia, then - might feel the now-stiffer chassis is a bit too rigid at times.

It feels much more like a sports car than a sporty car, with Gazoo Racing having honed the suspension to the tastes of Toyota president and master driver, Akio Toyoda. I’ve been to Japan. I know the roads there are a heck of a lot more agreeable than here.

Look, it mightn’t be a deal-breaker for the enthusiast, but the curious customer might find the ride a bit hard. 

The trade-off, of course, is terrific handling. It tucks into corners nicely, and with the reworked suspension (Macpherson front, multi-link rear), there’s less of that playful “please keep pushing me so we can have some slidey oversteer” character to it. It will drift, no doubt. But in the last 86, it didn’t take much effort to make that happen.

The steering is excellent, with terrific accuracy and weight, and decent feel through the wheel, too. You don’t feel every single thing at the front axle, but you do have a better gauge of it than you might have in the last GT grade, which famously ran those Prius tyres that were part of the reason sliding it around was a lot easier, too. The rubber on the new GR86 is far better - the GT runs Michelin Primacy HP (215/45/17), and the GTS has Michelin Pilot Sport 4 (215/40/18).

Look, it's still a lot of fun. But it’s fun in a different way. I actually prefer the last one in terms of the drive experience - even though this one is technically more impressive in all the important ways.

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).

Toyota’s five-year/unlimited kilometre warranty runs to the GR86, too. And if you maintain your car with the brand, that extends out to seven years for the powertrain.

The brand offers a capped-price servicing plan for five years/75,000km - meaning servicing intervals of 12 months/15,000km. 

Is it fairly priced when it comes to maintenance costs? Well, at $280 per visit for the first five services, it represents an annual saving of about $215 over the equivalent Subie. So that’s a nice way to recoup a bit of the cost.

There’s no included roadside assist, which you do get if you buy a BRZ.

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.
