Jaecoo J5 vs Mercedes-Benz G63

What's the difference?

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 Mercedes-AMG G 63 isn't for shrinking violets. It's bold, fast, and loud, and in second-generation form massively improved dynamically and technically. It's a lot of money, but there's a lot to love, and here's hoping it stays around for decades to come.

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.

The original (W460) G-Glass, then known as the G-Wagen (or Geländewagen for cross-country vehicle), was launched in 1979 as an ultra-capable off-roader, soon favoured by armies the world over. Arriving here in 1982, its distinctive, slab-sided form remained unchanged over the best part of four decades.

At close to 4.8m nose-to-tail, more than 1.8m across, and a bit over 1.9m tall, the G 63 is now longer (+110mm), wider (+106mm), and fractionally lower overall (-13mm), but still pulls off a convincing impersonation of a bread box.

Merc-AMG confidently quotes a drag coefficient (Cd) of 0.55 for the G 63, which isn't as bad as a brick (around 2.0… I Googled it) although it is in the same league as a heavy truck.

But it's the car's unique, upright stance, complete with pumped wheelarches and old-school flat glass, that sets it apart and draws people in. Looking more like a take-no-prisoners, functional device than a luxury cruiser, I can assure you it attracts as many admiring looks and comments as a low-flying supercar wedge.

The new-gen G 63 features AMG's vertically slatted 'Panamericana' grille, and our test example was fitted with the optional 'Night Package' ($5900) adding a range of dark exterior details including tinted indicator lenses, dark tinted glass, black exterior mirror shells and spare wheel ring, other black trim pieces and painted areas, as well as 22-inch AMG forged alloy rims.

Also worth noting, Merc has retained the G-Class's solid metal door handles, complete with the mechanism's unmistakable 'click-clack' opening and closing sound. Nice touch.

Inside, the biggest change is the upgrade from a conventional dual-gauge instrument cluster and central media stack to a pair of 12.3-inch digital screens, forming a sleek widescreen display, and bringing the G 63 in line with other recent Merc offerings.

Similarly, the gearshift moves from a traditional console-mounted set-up to Merc's 'Direct Select' lever on the steering column (exactly where the indicator stalk is located in 90 per cent of right-hand drive cars).  And the standard flat-bottom, leather-trimmed 'AMG Performance' steering wheel is a racy addition.

Like the exterior door handles, another tip of the hat to the car's heritage is retention of the horizontal grab handle ahead of the front passenger on the dash above the glove box. Nice to have something to hold on to if the going gets rough.

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.

The G-Class has never been a particularly squeezy proposition for passengers or cargo, but an extra 40mm in the wheelbase adds even more breathing space.

Getting in is the first step, and it's a big one. At 183cm tall, in an athletic mood, I could grab the A-pillar and swing up into the driver's seat in one vaguely respectable movement.

But, those side steps aren't just for show, and at the end of a long day provide a handy staging camp between terra firma and the lofty pilot's chair.

Once on-board there's plenty of room up front, with adequate storage including a bin between the seats (now with a double door opening rather than a single hinged lid), a modest glove box, oddments space and two cupholders in the centre console, and bins with space for bottles in the doors.

There's a 12-volt power outlet in the front, second row and cargo area, while there are two USB ports in the centre console bin and a charging USB port in the second row.

In the back I could have donned a dusty Akubra and still had headroom to spare, with generous foot room, and a substantial gap between my knees and the driver's seat (set to my position).

A fold-down armrest incorporates a pair of cupholders (as well as a through-port to the cargo space for long items) and there are map pockets on the front seat backs as well as space for bottles in the doors. Two adjustable air vents in the rear of the front centre console, and another pair in the B-pillars also provide climate-controlled air to those in the rear.

With the rear seats upright boot volume is quoted at 454 litres (VDA); enough to easily swallow our three-piece hard suitcase set (35, 68 and 105 litres) or the CarsGuide pram, or a largest-suitcase-and-pram combo.

There are tie-down shackles in each corner of the floor, usefully bright lighting, a netted storage area on the passenger side (containing five fluorescent emergency vests), and folding the 60/40 split rear seat liberates even more space.

Unfortunately, gaining access to that load space is fraught with compromise. First, the single-piece rear door hinges vertically and opens from right to left. No problem when you've nosed into a shopping centre space, but not so great when you're parking nose-to-tail on the left-hand side of the road.

That means you typically have a small space between you and the car behind to get the door open, and when it is at 90 degrees, you're blocked from unloading things onto the footpath until you've shut the door.

As well as that, the door has a full-size spare (alloy) wheel and tyre attached to it. Good because a full-size spare is welcome, and bad because it makes the already bulky door even heavier.

Those keen on towing things will be pleased to hear the G 63 is rated to haul up to 3.5 tonnes of braked trailer and 750kg unbraked.

Okay, you're laying down a quarter of a million bucks ($247,329 before on-road costs) and it's fair to expect some serious tech and standard equipment to keep you feeling warm and fuzzy after you're finished impressing friends and family with the G 63's howling acceleration.

For a start, there's a bunch of leading-edge safety tech on-board (detailed in the safety section below), and as expected that substantial cost-of-entry brings an extensive list of luxury features.

We've touched on the twin 12.3-inch 'Widescreen Cockpit', and available media includes digital radio and TV tuner, internet connectivity and 3D nav (with dynamic route guidance), as well as smartphone integration with Apple CarPlay and Android Auto.

Audio is a thumping 15-speaker, and 590-watt Burmester surround sound system, and the ambient lighting set-up offers a choice of 64 colours.

Also included are 'Multibeam' LED headlights, 'AMG Ride Control' adaptive damping, a 'Parking Package' with 'Active Parking Assist' and 360 camera, a sliding glass sunroof (with tilt function), the selectable AMG sports exhaust system, keyless entry and start, the AMG Performance steering wheel (trimmed in nappa leather), and 21-inch AMG '5-Twin spoke' alloy wheels.

Then there are the three 100 per cent differential locks (plus an 'off-road information centre'), electronically adjustable front seats (ventilated front and heated front and outer rear), steering column and mirrors (with memory function), three-zone climate control, nappa leather upholstery, a leather-finished dashboard with open-pore ash wood trim, a 'Dinamica' microfibre roof liner, and an AMG-specific IWC design analogue clock. Plus, the 'Dynamic Select' system enables a choice of pre-set driving profiles or individual settings.

The optional 'Exclusive Interior Plus Package' ($10,300) fitted to 'our' car adds deluxe nappa hide on the dashboard, door centre panels and grab handle, as well as a diamond quilted treatment on the seat centres, a black 'Dinamica' roof liner, velour floor mats (with edging in nappa leather), a frameless interior mirror and air vents in 'Silvershadow'.

On top of that the test vehicle was optioned with the 'Night Package' ($5900) detailed in the Design section, and Designo 'diamond white bright' paint ($5900) for a manufacturer's recommended list price (MRLP) of $269,429.

That puts the G 63 in the same price and equipment ballpark as the supercharged V8 Range Rover Autobiography ($268,900), twin-turbo V8 Porsche Cayenne Turbo ($239,400), and its Mercedes-AMG GLS 63 sibling ($221,729), powered by a version of the 5.5-litre twin-turbo V8 used in the first-gen G 63.

An impressive trio of alternatives, but in reality the idiosyncratic G 63 doesn't have any direct competitors, and for those who give in to the pull of its powerful tractor beams value-for-money becomes a uniquely personal concept.

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 G 63's 4.0-litre (M177) all-alloy V8 is closed deck design using direct-injection and a pair of twin-scroll turbos to produce 430kW at 6000rpm and no less than 850Nm from 2500-3500rpm. That's 10kW/90Nm more than the 5.5-litre twin-turbo V8 it replaces!

To improve throttle response and optimise efficiency, the turbos are located inside the engine's 'V', improving air flow and shortening the distance from the exhaust side to the turbos, and in turn, from the turbos to the inlet side.

And the housings on the twin-scroll turbos are divided into two parallel flow channels connecting with separate ducts in the exhaust manifold, allowing fine management of the exhaust gas coming in and pressure going out. Result is more torque and even better response times.

Drive goes to all four wheels via a new 'AMG Speedshift' nine-speed, dual-clutch auto (replacing the previous seven-speed auto transmission) with paddle shifters and a multiple downshift function which will go to the lowest ratio possible as you keep squeezing the shift paddle.

The 'AMG Performance 4Matic' all wheel drive system is front/rear biased 40/60 (50/50 in the previous model), although if you want to head off-highway the G 63 still features three 100 per cent diff locks and low-range off-road gear reduction.

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.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 13.1L/100km, with the 4.0-litre, twin-turbo V8 emitting 299g/km of CO2 in the process.

Despite the fact cylinder management tech means the engine will run on four cylinders under light load, and start-stop (with 'glide mode') is standard, we managed 16.7L/100km (measured at the bowser) over a mix of city, suburban and freeway running. To be expected for such a big bus, especially one that constantly tempts you into squeezing the throttle just to hear the exhaust bellow.

Minimum fuel requirement is 98 RON premium unleaded, and you'll need 100 litres of it to fill the tank.

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.

Let's cut to the chase. The G 63's pure grunt overpowers its challenging aero profile to thrust this boom box on wheels from 0-100km/h in a claimed 4.5 seconds. And believe it or not, despite its greater length and width, it has enough power to punch a 240km/h hole in the air (maximum velocity is limited to 220km/h if you choose not to opt for the 'AMG Driver's Package').

The new electronic architecture brings with it the latest version of Merc's 'Dynamic Select' system with five driving modes adjusting the engine, transmission, suspension, steering and assistance systems right up to maximum attack Sport+ mode.

All 850Nm of peak torque is available between 2500-3500rpm and pinning the throttle anywhere in that band feels like lining up a runway and preparing to rotate for take-off.

The two-stage exhaust flap arrangement allows you to turn the noise up from growl to roar even at modest around town speeds, and the nine-speed transmission is sharp and positive, with the multiple downshift function (in manual mode) hilariously good fun.

The racy AMG sports seats are as grippy as they are comfortable, and the fat 295/40 Goodyear Eagle F1 rubber, wrapped around the optional 22-inch forged alloys, does a good job of keeping all that mass and momentum in control as the high riding G 63 careens around corners.

And speaking of mass, the job of hauling it from warp speed to rest sits with big ventilated discs all around (cross-drilled 400mm front/370mm rear), clamped by monster six piston calipers at the front and single piston at the back. They're progressive and reassuringly powerful.

So, the performance is as dramatic as ever, but when I think of previous Merc-AMG G-Class offerings, two main shortcomings come to mind... steering and ride.

The steering was like a laggy mouse, with a few beats separating input at the wheel from response at the front treads. And the damping came up short, with a bouncy ride par for the course.

Still sitting on a ladder-type frame, the new G's suspension was developed by Mercedes-Benz and Mercedes-AMG. And finally, it has a decent double-wishbone independent front-end, with a rigid axle at the rear and coil springs all around. Plus, a strut tower brace, Merc-AMG calls it a 'suspension bridge', now connects the front strut towers, increasing torsional rigidity.

Ride comfort, especially in the most compliant 'Ride Control' suspension setting and riding on the big 22s, is massively better. It's no limo. You'll still feel jittering over higher frequency imperfections. But it's way, way ahead of the first-gen version.

The steering system changes from a recirculating ball to rack and pinion, and is now variable ratio with electro-mechanical rather than purely hydraulic assistance. And it's also much improved. We're not talking about a Lotus Elise-style connection with the road, but the steering is clearly more predictable and responsive.

One thing that hasn't changed is an ocean liner-worthy, 13.6m turning circle. You'll need to plan ahead for U-turns and reverse parks, but enough parking cameras (including surround view) to please Cecil B DeMille are on hand to help.

It's like a whole new world with a familiar cover wrapped around a markedly improved package. But (there must be a but) visibility is still compromised by thick window and door pillars, and despite the new dash layout ergonomic efficiency is patchy, with some switches and knobs located in relatively awkward positions.

As mentioned earlier the G 63 features three 100 per cent diff locks and low-range off-road gear reduction. But forget breakover angles and wading depths. This 4x4 seeing off-road action is as likely as an Abbott 2.0 prime ministership.

Suffice it to say, this car wears the 'Schöckl' badge at the base of its B-pillar. And in case you were wondering, Schöckl is a 1445m mountain in Graz, the Austrian city where the G-Class is built (and big Arnie Schwarzenegger was born!).

In the second-gen G-Class's development, prototypes covered roughly 2000km over a five kay trail including gradients of up to 60 per cent and lateral inclines up to 40 per cent. So, despite its irrelevance, the off-highway box is ticked.

The second-gen G 63 hasn't been assessed by ANCAP or Euro NCAP but its new electronic architecture brings the car up to speed on active safety tech, now incorporating 'Distronic' cruise control with 'Active Distance Assist', 'Active Brake Assist', AEB (forward and reverse), 'Active Lane Keeping Assist', 'Blind Spot Assist', 'Adaptive High-Beam Assist', tyre pressure monitoring, and 'Traffic Sign Assist'. Plus, the 'Pre-Safe' system prepares the vehicle and occupants in the face of an inevitable collision.

And once that impact has occurred, you're protected by nine airbags, including rear seat airbags, full-length curtains and a driver's knee bag.

There are three top tether points for child restraints/seats across the back seat, with ISOFIX anchors in the two outer positions.

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.

Mercedes-Benz (and by extension Mercedes-AMG) offers a three-year/unlimited km warranty with 24 hour 'Road Care' emergency roadside assistance provide for three years.

Servicing is recommended every 12 months/20,000km and a capped price servicing plan is available at Silver and Platinum levels for up to five years/100,000km.
