Mercedes-AMG S63 vs Jaecoo J8

What's the difference?

Both of these vast vehicles are phenomenally comfortable - this is the kind of car that Mercedes does so well, and has done for decades. The S Class is rarely a disappointment but it's difficult to believe that such a big, heavy GT car can also dance the way the S63 does.

The S560 is far more weighted to being a GT - supremely comfortable with that active suspension, a growly, refined V8 and a cabin full of gadgets and comfort. The S63 is altogether more aggressive, to look at and to drive. Lopping the roof off both of them adds weight but, like any cruiser, also puts you out in the sun, the breeze and into your surroundings. Plus, in the case of the S63, you get more exhaust noise.

They're two very different cars and not just because of the engine. After all these years admiring it from afar, the S63 has delivered on my teenage expectations - fast, smooth and utterly mad.

It is hard to argue with the sheer amount of stuff you get in the J8 for the price. And that long warranty and capped price servicing program remove the stress of buying into a new brand.

The J8 might be more car than most people need due to its size and lack of third row seating.

It’s okay to drive but isn’t class leading and no hybrid option will count it out for the ever increasing number of Aussies looking to petrol-electric power.

The J8 is a solid machine and well worth a look if you are after glitz and glamour on a budget.

The S Class Coupe is obviously related to the sedan but manages a svelte appearance. Slimmer hipped and with a more Coke-bottle shape, the Coupe - if you squint a bit - has a bit of the classic old pagoda about it. Obviously you can't do pillars that slim anymore, but the glass roof takes away some of the visual weight inside and out. 

The cabriolet's roof is nicely integrated and looks good when it's  up, which isn't always the case.

They all look long, though. It's obvious to see why the cars all run on 20-inch wheels - anything smaller would look hilarious.

The cabin is a fairly sensible re-imagining of the E-Class. The big twin-screen layout of the dash and multimedia system seems a bit more at home here. The chintzy Burmester speakers in the doors let down an otherwise classy cabin, which steers clear of otiose vulgarity in looks and materials.

The J8 looks familiar but it's hard to remember where you’ve seen it before. There are shades of Mazda, Mercedes-Benz and Range Rover scattered throughout.

The J8 looks more native Jaecoo than the smaller J7, but either way it's a handsome machine in the metal.

Its large, prominent front grille with thick vertical slats gives it presence on the road. This is paired with a big JAECOO badge on the grille and dynamic LED headlights and DRLs.

It has a sleek side profile and does away with gaudy panel creases and sharp edges, which helps project its premium persona. This design is highlighted by its hidden door handles, well integrated roof rails and rear spoiler.

There is a rear light bar, which is the current must have styling item, and connects the tail-lights

Inside is where the action is.

It looks proper luxe, with soft touch and textured inserts all over. We spent the majority of our time in the Ridge AWD and on top of the dash is a type of soft synthetic suede and there are wood veneer-type inserts that give it a touch of class as well as some piano black highlights and plenty of premium feeling materials.

Even in the back seat, where some brands can cut costs, the J8 has a quality feel to it.

It is an impressive space for circa-$50,000.

Well look, if you end up in the back of the S Coupe, it's not a riot of space. Obviously it has back seats (the SL doesn't even squeeze a jump seat into its considerable length) but they're for occasional, if luxurious, use.

The boot is a reasonably decent 400 litres, obviously the cabriolet loses a few litres with the roof folded. Front and rear passengers will both enjoy a pair of cupholders and the whopping long doors will each hold a bottle.

Having only five seats in a car this big feels like a waste of space, and in reality it is. You’re now driving a very big and bulky car without the people carrying pros.

Very rarely will you need to use the giant 738-litre boot, but the ability to carry children’s friends or extended family is probably a more useful and regular scenario.

Up front there are plenty of storage options with lots of nooks and crannies in the centre console, including a sizeable and deep bin and good size pockets on the doors. Cupholders for both rows are a plus, too.

USB charging points for both rows are great. If you like to connect to Apple CarPlay via a cord and not wirelessly the port is down near the front seat passengers right foot, which is hard to access.

Additionally the wireless device charger is on the passenger side of the console. Both are hallmarks of a car originally designed to be driven on the other side of the road.

The back seat is huge, there is ample leg, shoulder and head room and it can easily accommodate adults or large teenagers.

The J8 comes in two grades: the two-wheel drive Track variant and the all-wheel drive Ridge. The variant names are tied into the brand’s adventurous image.

The Track is priced at a national $49,990 drive-away, which is about $5000 and $8000 cheaper respectively than the base Kia Sorento or Hyundai Santa Fe.

Jaecoo has thrown everything at the J8, except a third row of seats.

The Track grade has 20-inch alloy wheels, heated and ventilated front seats wrapped in real leather and topped off with a massage function.

There are dual 12.3-inch displays, one for the multimedia and the other for the driver. Apple CarPlay and Android Auto, sat nav and a 12-speaker Sony stereo are other highlights.

There are some clever functions too. When on a phone call it projects sound only through the two headrest speakers giving more privacy.

Three different scents can be diffused through the cabin, which might help override the drive-through food or old sports bag aroma in the boot.

It also has a panoramic sunroof, dual-zone climate control, power adjustable steering wheel, a head-up display (that projects vital information such as your travelling speed on to the windscreen in front of the driver) and a wireless device charger.

There isn’t much room left on the $54,990 drive-away Ridge AWD’s equipment sheet, but it manages to squeeze in a suede headliner, heated and ventilated rear window seats, privacy glass and electric door handles.

The Ridge also adds all-wheel drive grip with multiple drive modes such as 'Sport', 'Eco' and 'Normal' as well as 'Mud', 'Snow', 'Sand' and 'Off-Road' to best handle different conditions.

A more advanced active suspension system adjusts each wheel independently according to driving conditions to smooth out the ride.

In a win for buyers, both variants have a full size spare tyre hidden under the boot floor.

All four coupes and cabriolets ship with Daimler's formidable 4.0-litre twin-turbo V8. The S560 scores 345kW/700Nm to drive the rear wheels through Benz's own nine-speed automatic. With all of that available, the S560 will crack the ton in 4.6 seconds and make a wonderful racket on the way.

Moving on to the S63, the same engine delivers a massive 450kW/900Nm. The run from 0-100km/h is dispatched in just 3.5 seconds and if I thought the S560 made a good noise, the S63 with its standard sports exhaust makes a better one. Again, Mercedes' nine-speeder is along for the ride.

Power comes from a 2.0-litre, four-cylinder, turbo-petrol engine that makes 183kW and 385Nm, which is matched to an eight-speed automatic driving either the front or all four wheels.

That’s a decent amount of grunt and is on par with a Volkswagen Golf GTI, but the J8 weights about 1800kg in 2WD guise with AWD adding 100kg.

Those numbers are also short of the 206kW/422Nm delivered by the Santa Fe’s turbo-petrol motor but are better than the 200kW and 333Nm made by the Sorento’s non-turbo V6.

The lack of a hybrid option at launch, which is popular in rival machines, could prove to be a misstep.

Jaecoo said a plug-in hybrid version was under consideration, but is likely to come at a decent premium.

The lower-powered 560 drinks 98RON at the rate of 8.5L/100km for the coupe and 9.9L/100km for the heavier cabriolet.

The S63 ups the ante with 9.9L/100km for the coupe and an identical 9.9L/100km for the cab.

Our launch program contained some...er...spirited driving, which would explain the mid to high-teens fuel figures.

Jaecoo claims on the combined (urban/extra-urban) cycle the J8 Track 2WD will drink 8.3L/100km and the Ridge AWD will gulp 8.6L/100km, which is better than its similar sized rivals. But those rivals also have hybrid options that are more powerful and drink less fuel.

It also requires premium unleaded fuel, while the others drink the cheaper stuff.

A 65-litre fuel tank gives it a theoretical driving range of 755km in its thirstiest guise.

We didn’t get to spend enough time behind the wheel to do a thorough real-world test, and the majority of our drive was spent on high-speed arterial roads or motorways where petrol cars are at their most efficient. So we’ll reserve judgement until we undertake a more comprehensive test drive.

Let's start with the S560. That smooth V8 rumble is all you'll ever hear if you just slot into drive and go for a leisurely spin. The nine-speed automatic continues to be a revelation to me - in the GLC63 it's good and here, once again, it's excellent, finding the right gear for the occasion and riding the fat torque curve. Other nine-speed autos are not very good at all.

The test route for the S560 played to the strengths of the car. It had some lovely winding roads, which brought the trick suspension into focus - the Magic Body Control with curve function is hilarious. While the active suspension works hard at all times to ensure the ride is smooth and drama free, the Curve mode (no, really) actually leans the car into corners.

Those of you who remember the video game Wipeout 2097 will be big fans of Curve mode. As you approach a corner, you turn the wheel and then the car leans into the bend. This isn't active damping reading the road, it's the outside suspension lifting the car and the inside lowering it, so the car feels like it's gliding, like a hovercar. It's wild but oddly calming. Mercedes reckons it's great for those who get car sick. As I didn't have my wife on hand to test this theory - she chucks at the first sign of a corner - I couldn't verify this claim. That will have to wait.

The S63 AMG is a completely different proposition. The air suspension is more than up to the job of helping smother the effects of the car's considerable weight, meaning that no matter what you're up to, the car feels reasonably light on its feet. It never feels small, though, commanding the respect of the driver and plenty of space from other road users.

And boy, do you need some space if you kick the S63 into Sport mode. In true AMG style, the electronic reins relax and the big luxury coupe cheerfully kicks off. The tail will wriggle under an unsympathetic right foot, that signature V8 roar, crackle and hiss filling your ears. The S63 is always the harder-feeling car, but it delivers with a more sporting drive than the S560.

Being the generous soul I am, I volunteered to return the S63 to its home for the evening rather than consign it to the back of a truck. On the back roads I took to reach the highway, it was rock solid - fast, predictable and a lot of fun. Once I found the boring straight bits, it turned into a supremely comfortable cruiser, ticking along in ninth at the legal limit (and being Melbourne, it was very much the legal limit), dispatching overtaking with barely a flex of a toe. 

The active cruise took the stress of keeping away from the State Revenue Office's clutches while being quiet and utterly pleasant.

There is a clear line of demarcation between the Chery brand and Jaecoo, and the J8 drives substantially better than Chery’s line of budget-friendly Tiggo SUVs.

We spent most of our time in the Ridge AWD and the fancy active suspension makes a huge impact. It keeps the vehicle in check through corners, exerting excellent body control. It's a bit unnerving how flat the car sits through the bends with next to no body roll.

Despite riding on giant 20-inch wheels the J8 soaks up bumps and road imperfections with ease.

The Track 2WD falls off noticeably in this regard without the active damping.

The steering is light and a bit floaty, which saps confidence when entering corners as there isn’t a lot of feedback on what is happening underneath you.

The steering ratio seems a bit wide of the mark, the wheel needing more input than we'd like.

The engine delivers decent grunt and it's tuned for leisurely acceleration rather than performance. 

There was the odd occasion when the transmission and the motor weren't quite in sync and you might get a bit of hesitation and then too much oomph all at once.

It has no problems getting up to speed on the motorway and handles overtaking with ease. 

Jaecoo, and its parent company Chery, have worked hard on the safety tech calibration and it's much less intrusive on the J8 than some earlier models. This applies especially to the lane keep assist, which only steps in when needed. There are far fewer bings and bongs than before.

You sit up nice and high in the J8, which gives you a good view of the road ahead, but the sloped rear window restricts vision out the back compared to boxier shaped SUVs.

It is a big rig and you feel that on the road, even the Jaecoo team said you’d notice the width of the J8 on the road, which might be an issue if you live in compact inner city areas or deal with cramped car spaces.

The J8 hasn’t been tested by ANCAP yet, but it is expected to get the same five-star score as the J7.

One thing that jumps out is the AWD version gets two more airbags than the 2WD variant.

The Ridge AWD adds two side airbags to the rear row, while the Track 2WD makes do with curtain airbag protection only in the back seat.

It covers all the bases for active safety with auto emergency braking, lane keep assist, lane departure warning, rear cross-traffic alert with auto braking, blind-spot detection, speed recognition, active cruise control and door opening alert.

Mercedes offers a three-year/unlimited-kilometre warranty with roadside assist for the duration.

The company also offers both service plans (where you pay up-front as part of the vehicle purchase) and capped-price servicing on the coupes. Servicing over three years is in the order $2500.

Jaecoo backs its cars for eight years and unlimited km, which is one of the most comprehensive in the business. MG, Mitsubishi and Nissan all have 10 year warranties but are not unlimited km and Mitsubishi and Nissan need you to only service at their dealerships.

Jaecoo backs this up with an eight-year capped priced servicing program, which costs $2952 for the Track 2WD and $3452 for the Ridge AWD. That’s slightly on the expensive side but better than being at the whim of the mechanic after five years.

Keep in mind the fourth and eight year services are biggies, costing $699 and $799 in the Ridge AWD and $499 and $599 in the Track 2WD.

You also get eight years of roadside assistance if you service your car at the dealership.
