Mercedes-AMG S63 vs Jaecoo J5

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.

The Jaecoo J5 EV makes a strong first impression and a quieter long-term one. The J5 looks the part, feels comfortable and covers all the basics well, making it an easy choice for buyers who want an affordable, practical EV without too many compromises.

It’s a solid effort overall, though even at this lower price point a few more rear-seat features would be welcome - especially given this is the only grade currently available. However, it hits the right notes when it comes to ownership and value which will be its strongest pull.

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 Jaecoo J5 EV is a handsome-looking small SUV. Its suite of LED lighting, 18-inch alloy wheels and upright, robust silhouette give it plenty of presence, particularly for something positioned at the affordable end of the EV market. That said, originality isn’t really its strong suit. The design, especially from the rear, feels heavily inspired by a Range Rover. Imitation may be the highest form of flattery but Jaecoo could have pushed the design in a slightly more distinctive direction.

It looks good on the road, though, and inside, the J5 has a genuinely airy feel. Light-coloured synthetic upholstery and the expansive panoramic glass roof help the cabin feel open and welcoming, particularly from the front seats. The design is modern and tech-focused, with the large 13.2-inch display taking centre stage on the dashboard.

The overall layout is clean and undeniably premium in its presentation, though it doesn’t bring a great deal of personality with it. That’s becoming a familiar theme, especially in this part of the EV market, where minimalism and screens often take priority over character.

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.

The Jaecoo J5 EV's cabin is spacious with both rows offering ample head- and legroom. A flat floor also helps the middle rear seat feel more usable than usual, which is always appreciated. Up front, the seats are very comfortable, with their added adjustment, heating and ventilation making a noticeable difference on longer drives. The rear seats are well padded with decent back support, so passengers in the second row shouldn’t feel short-changed.

Access to both rows is good with wide door apertures and an easy step in/step out height. My main quibble here is the keyless entry set-up. Unless you enable proximity unlocking through the multimedia system the doors aren’t truly keyless. Even then, the system can be inconsistent. That means occasionally having to reach for the key fob, which is frustrating when your hands are full.

Storage is one of the J5’s stronger suits. Up front, it’s easy to keep things neat thanks to a large glove box and a deep, if slightly narrow, middle console. There’s also a clever open shelf beneath a centre console that houses cupholders and phone storage, including a wireless charging pad. A small hidden pocket behind the media display adds to the storage count, although I’ll admit I regularly forget it exists.

Rear passengers get a couple of map pockets, drink bottle holders and cupholders. Beyond that, amenities are limited. There’s a single directional air vent and a USB-A port, but not much else to keep older kids or adults entertained.

Technology is fairly straightforward, although almost everything is accessed through the touchscreen. The multimedia system is crisp and responsive, with wireless Apple CarPlay and Android Auto working well, however it misses out on built-in satellite navigation and any meaningful apps. That said, there is a karaoke app tucked away in the system, which will undoubtedly delight someone, somewhere.

Charging options up front include a USB-A and USB-C port, along with a 12-volt socket. There’s also a USB-A port near the rear-view mirror, which is handy if you’re planning to install an aftermarket dash cam.

Jaecoo pitches the J5 as pet-friendly, with upholstery designed to be easy to clean and resistant to wear. In practice, I’d say that claim comes with caveats. Jaecoo clearly hasn’t met my son or my German Shepherd, and it took a fair bit of elbow grease to properly clean the cabin. Staying on top of messes will be key if you want the interior to keep looking fresh.

The boot offers up to 480L of capacity, which is strong for the class, and the flat load floor makes it easy to slide items in and out. There are no power ports or sockets, which feels like an odd omission for an EV. You also get a repair kit instead of a spare tyre, despite there being enough space to accommodate one. A 35L frunk adds some extra storage flexibility, and the powered tailgate is a welcome inclusion.

We’re testing the only Jaecoo J5 EV variant available at the moment, ahead of petrol and hybrid versions due to arrive later this year. Right now, it’s being offered with a limited-time drive-away price of $36,990. Once that offer expires, it reverts to a $35,990 MSRP, which sees it tie with the BYD Atto 2 Premium as the most affordable EV in its segment.

Step up from there and you reach the J5’s sister model, the Chery E5 Ultimate, priced from $40,990 MSRP. The MG S5 EV Essence 62 sits close by, starting from $40,490 MSRP.

On paper, the J5 hits a few more notes than its key rivals and that’s worth acknowledging. There’s a solid list of premium-style features, including electrically adjustable front seats with heating and ventilation, a panoramic glass roof, powered tailgate and synthetic leather-style upholstery.

Technology is similarly generous. You get a large 13.2-inch touchscreen multimedia display paired with an 8.88-inch digital instrument cluster, along with wireless Apple CarPlay and Android Auto. A 360-degree camera system is standard, as are two USB-A ports, a single 12-volt socket up front and a wireless charging pad.

That said, there’s only one USB-C port in the entire cabin, and no charging ports or power sockets in the boot, which feels like an odd omission in an electric SUV. Accessing the vehicle-to-load function also requires an adapter via the external charging port, rather than a more user-friendly internal outlet.

Despite its sharp pricing, the J5 is offered in just one high-spec grade and that raises expectations. In that context, the rear seat feels a little underdone. It misses out on several amenities you’d reasonably expect in a flagship-style model. While that’s not unusual for an EV at this end of the market, it still feels like a missed opportunity to stand out.

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 Jaecoo J5 EV is powered by a single electric motor sending 155kW/288Nm to the front wheels. That’s enough to see it sprint from 0-100km/h in a claimed 7.7 seconds. Those figures stack up well relative to the J5's positioning in the segment.

This isn’t a performance-led EV and it doesn’t pretend to be. Instead, the J5 delivers its power in a way that feels competent and predictable rather than 'exciting'.

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 Jaecoo J5 EV uses a Type 2 CCS charging port and can accept up to 10.3kW on AC power via a three-phase connection, along with DC fast charging speeds of up to 130kW. On a suitable fast charger, Jaecoo claims a 30 to 80 per cent charge can be completed in as little as 28 minutes. That’s a solid result for this segment, with only the MG S5 EV offering higher DC charging capacity and quicker top-up times.

The J5 has a 58.9kWh lithium-iron phosphate battery and a 402km (WLTP) driving range. Both its sister model, the Chery E5, and the MG have slightly longer ranges. It's not surprising but it means it's an EV better suited to the city where you can keep it regularly topped up.

Official energy consumption is listed at 14.3kWh/100km. After a mix of longer drives and urban running, my average settled around 15.4kWh/100km, which is a respectable result overall and broadly in line with expectations.

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.

The Jaecoo J5 EV has plenty of power on hand, with good pick-up when you need it for hills or overtaking. It feels responsive enough for everyday driving, without ever feeling aggressive or overly eager.

Steering is light, and the suspension leans towards the softer side. Around town that works well, offering a comfortable ride. On faster roads or through corners, however, it can feel a little unsettled, and the J5 isn’t particularly convincing on the open road.

Visibility out the front and sides is strong and the driving position gives you a fairly commanding view of the road, which makes day-to-day city driving straightforward.

There are three levels of regenerative braking, but even on the lowest setting it can feel abrupt. Some passengers reported feeling queasy and maintaining a smooth, consistent speed can be tricky as the car has a tendency to lurch.

Parking is generally easy thanks to the J5’s compact footprint and a clear 360-degree camera system. That said, the aggressive regen braking can make low-speed manoeuvres, particularly reversing, more challenging than necessary, as it’s hard to get the car to creep smoothly.

The J5 hasn’t been assessed by ANCAP yet and is unrated but it has a good suite of safety equipment included. There are seven airbags, intelligent seat belt reminders, ISOFIX anchors, three top-tether anchor points, front/rear parking sensors and a 360-degree view camera system.

There’s also blind-spot monitoring, lane departure alert, lane keeping aid, forward and rear collision warning, side exit assist, a driver monitoring system, autonomous emergency braking and adaptive cruise control. The J5 EV misses out on emergency call capability.

Most of the driver assist systems aren’t intrusive, although the driver attention monitoring can ping more than it’s needed and the adaptive cruise control is best without the assisted steering on.

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.

Ownership is one of the J5’s stronger points. The number eight is associated with good fortune in Chinese culture and Jaecoo has clearly leaned into it here!

It's offered with an eight-year/unlimited km warranty, eight years battery cover and roadside assistance, plus eight years of capped-price servicing where workshop visits average a low $190 per visit (which is very good).

Servicing is required every 12 months or 20,000 kilometres and for now the service network is fairly small, with around 50 centres nationwide. They’re mostly found in major cities, which is something to keep in mind depending on where you live.
