Mercedes-Benz GLS vs Jaecoo J5

What's the difference?

The GLS63 is an intimidating beast from afar, but it rewards its occupants in almost every way. Yep, there really isn’t a box it doesn’t tick without serious compromise, such is its breadth of capability.

If there was ever a Swiss Army Knife of cars, the GLS63 is definitely a contender for the title, one that makes it very hard to wipe the smile off your face. Just make sure you can fit it in your garage first…

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.

If the GLS63 was a Marvel superhero, it would undoubtedly be the Hulk. Simply put, it has road presence like few others. In fact, it’s frankly menacing.

Of course, the GLS is already pretty intimidating due to its sheer size and blocky design, but the GLS63’s full-fat AMG treatment takes it to another level.

Naturally, the GLS63 gets an aggressive body kit, with its purposeful bumpers, side skirts and rear spoiler serving as instant reminders of what you’re dealing with, but it’s AMG’s signature Panamericana grille insert that really hammers home the point.

Around the side, the GLS63’s 22-inch alloy wheels with staggered tyres (front: 275/50, rear: 315/45) make their presence known, positioned below the wheelarch extensions.

That said, some fun’s also had at the rear end, where the GLS63’s diffuser element integrates the foreboding sports exhaust system with quad tailpipes very neatly.

The focused Multibeam LED headlights also look the part, while the opposing LED tail-lights tie everything together outside quite nicely.

Inside, the GLS63 stands out from the GLS crowd with its sports steering wheel with Dinamica microfibre accents, and multi-contour front seats, which are covered in Nappa leather alongside the armrests, dashboard and door shoulders and inserts.

Of note, the doors bins are unfortunately of the hard plastic variety, which is very disappointing in a vehicle that costs this much. You would expect that cow hide would also been applied to them, but alas it isn’t.

The GLS63’s black headliner serves as an obligatory reminder of its sporting intent, and while it makes for a dark cabin, metallic accents are prominent throughout, while the optional trim (our test vehicle had carbon-fibre) mixes things up, alongside the ambient lighting.

And let’s not forget the GLS63 is still loaded with plenty of cutting-edge technology, including a pair of 12.3-inch displays, with one the central touchscreen and the other the digital instrument cluster.

Both are powered by Mercedes’ class-leading MBUX multimedia system and feature Apple CarPlay and Android Auto support. This set-up arguably remains the best there is today thanks to its speed and breadth of functionality and input methods.

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.

Measuring 5243mm, 2030mm wide and 1782mm tall with a 3135mm wheelbase, the GLS63 is an upper-large SUV in every sense of the term, which means it’s also very practical.

For example, cargo capacity below the load cover is decent, at 355L, but stow the 50/50 power-split-folding third row via the boot and it’s very good, at 890L, or drop the 40/20/40 power-split-folding middle bench, too, and it becomes a cavernous 2400L.

Better yet, the boot’s aperture is almost square, and its floor’s flat, while there’s no load lip to contend with, making loading bulkier items even easier. Up to four tie-down points are also on hand (depending on seating configuration) to secure loose cargo.

Under the false floor is the space-saver spare, which is to be expected, but what isn’t expected necessarily is the fact there’s also enough room there for the cargo cover when it’s not in use, which would be the case if six or more passengers are regularly onboard.

Moving into the power-sliding second row, the GLS63’s practicality is once again brought to the fore, with up to six-plus inches of legroom available behind my 184cm driving position.

There’s also two inches of headroom with the panoramic sunroof in situ, not to mention just enough toe-room. The GLS63’s small transmission tunnel and sheer width also mean three adults can be seated on the middle bench with few complaints.

Amenities-wise, the second row has map pockets on the front-seat backrest and a small fold-down cubby below the rear climate controls, with it containing two slots for smartphones and a pair of strategically placed USB-C ports.

The rear door bins can take one large bottle each, while a fold-down central armrest is also on hand, featuring a shallow tray and retractable (and flimsy) cupholders.

Alternatively, the $2800 Rear Seat Comfort Package fitted to our test vehicle subs in a tablet that can control the multimedia system, a wireless smartphone charger and a small cubby into the former, as well as a heated/cooled cupholder atop the rear of the centre console.

In the third row, it’s not quite as roomy if you’re an adult. With the middle bench in its most accommodating position, my knees still brush up against its backrest, which is to be expected given it’s primarily designed for children. I also have an inch of headroom there.

Nonetheless, getting in and out of the third row is relatively easy as the power-operated middle bench tumbles forward and provides just enough space to make entry and exit somewhat graceful.

When seated, rear occupants are treated to two USB-C ports and one small cupholder each, so they’re arguably taken better care of than those in the middle.

Child seats are well and truly accommodated, with four ISOFIX and five top-tether anchorage points fitted across the second and third rows, although the latter will inevitably prove to be a much tighter fit.

The driver and front passenger are still taken care of, with a front cubby taken up by two heated/cooled cupholders, a wireless smartphone charger, two USB-C ports and a 12V power outlet, while their door bins take one large and one small bottle each.

In-cabin storage options include the large central storage bin, which hides another USB-C port, while the glovebox is on the smaller side, with about a third of it taken up by the fragrance, which is pumped into the cabin to ensure the interior always smells its best.

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.

The GLS63 is powered by a familiar 4.0-litre twin-turbo V8 petrol engine, with its version producing a thumping 450kW of power at 5750rpm and 850Nm of torque from 2250-5000rpm.

This unit is mated to a nine-speed torque-converter automatic transmission and AMG’s fully variable 4Matic+ all-wheel-drive system with torque vectoring and a rear limited-slip differential.

This set-up also features Mercedes’ EQ Boost 48V mild-hybrid system, which actually gives a 16kW/250Nm electric boost in short bursts, such as when accelerating off the line.

Speaking of which, the GLS63 sprints from a standstill to 100km/h in just 4.2 seconds, while its top speed is electronically limited to 250km/h.
 

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 GLS63’s fuel consumption on the combined-cycle test (ADR 81/02) is 13.0L per 100km, while its carbon dioxide emissions are 296 grams per km. All things considered, both claims are unsurprisingly high.

In our real-world testing, we averaged a fearsome 18.5L/100km over 65km of driving, split between highways and country roads, so not your usual mix. A very heavy right foot definitely influenced that result, but don’t expect to do too much better in a normal run.

For reference, the GLS63’s 90L fuel tank can be filled up with 98RON petrol at a minimum.

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.

Frankly, the GLS63 has absolutely no right being as capable as it is. It’s a really big bus that’s legitimately convinced it’s a sports car half its size.

Being a GLS variant, the GLS63 has independent suspension consisting of four-link front and multi-link rear axles with air springs and adaptive dampers, but its party trick is the addition of active anti-roll bars.

In what feels like magic, the GLS63 is simply not intimidated by corners, despite having massive dimensions and a considerable 2555kg (kerb weight) to deal with.

The active anti-roll bars make the GLS63 so much easier to drive fast through the twisty stuff, almost eliminating body roll, taking one key variable out of the equation for the driver. Active engine mounts are also fitted, helping to settle things even further.

The electric power steering on hand is also good. It is speed-sensitive and has a variable ratio, which basically makes the set-up more direct when it needs to be. It’s typically light in hand, too, until one of the sportier drive modes is engaged and extra heft is added.

So, handling is scarcely believable, which means the ride must be compromised, right? Yes and no. With the adaptive dampers in their softest setting, the GLS63 is very compliant. In fact, we’d say it feels luxurious when compared to other high-performance SUVs.

That said, our test vehicle was fitted with the optional 23-inch alloy wheels ($3900), which look the part but expose sharp edges and other road imperfections, not to mention generate noise easily heard inside. Naturally, feedback is exacerbated in the sportier drive modes.

Anyway, there’s more performance, and the GLS63 has the rest in spades. Its engine is a powerhouse in every sense of the word. It’s so powerful, in fact, that it hilariously hunkers down off the line or when suddenly accelerating at low speed.

Thanks to the mild-hybrid system, wads of torque is available from the get-go, making for a highly responsive driving experience, even in those rare moments when the engine isn’t on song.

While not as characterful as some of the other members in the 63 series, the GLS63 still makes some thoroughly entertaining noises, with its sports exhaust system popping like mad while on the overrun.

All of this ability is very well and good, but you need to be able to pull up quickly, and the high-performance braking package (400mm front and 370mm rear discs with six-piston fixed callipers and single-pot floating stoppers respectively) mercifully does exactly that.

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.

As with all Mercedes-AMG models, the GLS63 comes with a five-year/unlimited-kilometre warranty, which currently sets the standard for the premium market. It also comes with five years of roadside assistance.

The GLS63’s service intervals are relatively long, at every 12 months or 20,000km (whichever comes first). Better yet, it’s available with a five-year/100,000km capped-price servicing plan, but it costs $4450.

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.
