Mercedes-AMG S63 vs Gac Emzoom

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.

GAC isn’t messing around with the Emzoom Luxury. It’s undeniably eye-catching, priced well and carries just enough of a premium aesthetic to draw attention.

Is it the best small SUV I’ve driven? No. It does enough to avoid being overlooked, but it’s not quite reinventing the wheel.

What it does well is deliver a comfortable, easy urban runaround with strong equipment for the price. However, the safety calibration and overall breadth of systems feel like areas that still need attention.

All up, it gets a lot right for the money, but doesn’t quite land a knockout punch.

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.

Up front, the Emzoom offers the most space and it’s where it feels most comfortable. The seats are supportive enough for longer trips, and while only the driver’s side is electrically adjustable, that’s not unusual at this price point. Wide door apertures make getting in and out easy and there’s enough elbow room so it doesn’t feel cramped.

In the rear, space is also surprisingly generous for the segment. The flat floor helps with legroom and headroom remains good despite the panoramic sunroof.

Storage is well thought through and generous. Up front, there’s a glove box, a deep centre console and a dual-phone tray that incorporates a ventilated wireless charging pad. There are two cupholders and a drink holder in each door storage bin. You also get an additional shelf underneath with both USB-A and USB-C ports, which helps keep cables and clutter out of the way.

In the rear, amenities are solid, with rear air vents, a fold-down armrest with two cupholders, map pockets and even small device pockets for added practicality. There's a drink bottle holder in each door and a single USB-A port behind the centre console.

Around the back, the boot offers a wide opening and a level load space, making it easy to use day-to-day. Capacity sits at 341 litres, which is enough for a weekly grocery run or a weekend away. There’s a spare tyre tucked under the floor and a powered tailgate is standard.

The tech is easy to live with, too. The media system is intuitive with clear graphics and a responsive touchscreen. Wireless Apple CarPlay connects quickly without fuss, and there’s also wireless Android Auto. Sound quality from the six-speaker system is crisp and the digital radio and Bluetooth hold a steady connection (where some rivals can struggle).

For now, the GAC Emzoom range is about as simple as it gets. There’s a single, well-specified Luxury grade on offer, priced from $25,590, before on-road costs.

That puts it right in the mix with key Chinese rivals like the GWM Haval Jolion Lux, which starts at $28,990 (MSRP) and the MG ZS Vibe Turbo at $24,990 (MSRP). It also significantly undercuts more established mainstream options such as the Kia Seltos Sport+, which opens at $37,550, before on-roads.

The Luxury arrives well equipped. You get an electric driver’s seat with ventilation, synthetic leather upholstery, a panoramic sunroof with tilt and slide function, and auto-flush door handles. There’s also a leather-wrapped steering wheel, a 360-degree camera system, parking assist and a blind-spot view monitor.

Technology leans towards the premium end, too. A 14.6-inch central display is paired with a 7.0-inch digital instrument cluster, along with ambient lighting, wireless Apple CarPlay and Android Auto and a wireless phone charger. There are two USB-A ports, a single USB-C port up front, a 12-volt socket and a six-speaker DTS sound system.

It’s the smaller details that round things out nicely. Auto LED headlights, rain-sensing wipers, dual-zone climate control, a temporary spare tyre and a powered tailgate are all included as standard.

All up, it’s a strong package for the price.

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.

The Emzoom Luxury is front-wheel drive and powered by a 1.5-litre turbo-petrol engine producing 125kW and 270Nm.

That gives it a slight edge over the GWM Haval Jolion, which sits at 105kW and 210Nm and puts it more in line with the MG ZS Vibe Turbo and Kia Seltos Sport+. On paper at least, it’s competitive for the segment and suggests there’s enough performance on tap for daily driving.

It’s paired with a seven-speed dual-clutch auto transmission. Around town, it can feel a little clunky at lower speeds, particularly in stop-start traffic, but it settles down as you pick up pace and feels much smoother on the open road.

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.

The Emzoom Luxury has a 47-litre fuel tank and a claimed combined cycle (urban/extra-urban) consumption figure of 6.6L/100km, which gives it a theoretical driving range of up to 712km. That’s more than enough to comfortably get through a week of mixed driving.

In the real world, my trip computer returned 6.2L/100km after a mix of mostly urban driving and a longer highway run. That’s a strong result and reinforces its credentials as an easy urban runabout.

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.

On the road, the Emzoom has enough power to feel spritely and capable, whether you’re darting around town or merging onto the highway. That said, the way it delivers that power at lower speeds can feel a little inconsistent. There were moments where lifting off the accelerator didn’t translate to an immediate response, with the car continuing to surge forward briefly. Which made for a few 'eek…' moments during the week.

Handling is on the sharper side for the segment. The steering and suspension are well judged, giving it a slightly zippy, eager feel through corners without tipping into harshness. Braking, however, can feel a touch spongy underfoot, which takes away from that otherwise confident set-up.

Visibility is a mixed bag. Thick pillars, a relatively low window line and a small rear view can make it feel hemmed in from the driver’s seat. Though, the blind-spot camera feed popping up on the display takes some of the guesswork out of lane changes.

Ride comfort is solid overall. It handles bumps well enough, and a longer drive proved comfortable, although there is a low level of road noise that creeps in at higher speeds.

Where the Emzoom really shines is around town. It’s easy to manoeuvre, with an 11.2-metre turning circle that makes tight streets and car parks feel manageable. The 360-degree camera system is clear and makes parking a relatively stress-free experience.

The GAC Emzoom hasn’t been tested by ANCAP yet and is unrated. It comes with six airbags, which is on the lower side for this class, and there are a few notable omissions.

Features like rear cross-traffic alert, side exit assist and emergency call functionality aren’t included. While there is a blind-spot view monitor that displays a live camera feed when you indicate, it doesn’t appear to have a traditional blind-spot warning system with indicator lights in the side mirrors.

The core safety suite is there. You get autonomous emergency braking, forward collision warning, lane- keeping aid and lane-departure warning, along with seatbelt reminders for all seats, a tyre pressure monitoring system and hill descent control. There are also two ISOFIX points and three top-tether anchor points for child seats.

Where it falls short is in execution. The steering assist function tied to the adaptive cruise control is overly intrusive, with noticeable inputs that make it difficult to use comfortably. Given the amount of highway driving I do each week, it’s not a system I found myself wanting to rely on.

Overall, the safety offering doesn’t feel as comprehensive or as well calibrated as it could be, which takes some shine off an otherwise well-equipped package.

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.

The Emzoom is offered with a seven-year/unlimited km warranty which is great for the class.

Service pricing has yet to be finalised for the Emzoom and for now the service network is tiny, with only around 10 centres nationwide but you can undergo authorised repairs through places like MyCar.
