Mercedes-Benz S300 vs Jaecoo J5

What's the difference?

The 2018 Mercedes-Benz S-Class remains a technological tour de force, a luxury sedan to be reckoned with - one that has safety, technology, comfort, finesse and performance all rolled into a stylish package. 

It's hard to see why you'd need anything more than the S 350 d, which is now much more attractively priced. It'd be my pick, but I'd have to get the Energizing Comfort Control package, and probably the AMG styling pack, too. And even then it would cost less than its predecessor.

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.

I swear it has been facelifted, and the changes are bigger than they might appear. There is no doubt that the S-Class shape is largely unchanged, but the German company has kept the modifications minimal in the scheme of things.

That doesn’t mean those changes are unnecessary, though. The new headlights, for example, are standard on every model, and are constructed with 84 LEDs (including three for the daytime running lights), and of course they’re adaptive with automated high-beam - meaning they’ll shield other road users from the glare of the lights at night. And the lights themselves will throw a main beam up to 650 metres, according to the company. 

Other things are slightly more cosmetic, like the revised three-bar grille treatment, new front and rear bumper designs that feature broader sculpted sections to widen the stance of the car, and there are new LED tail-lights as well.

The smallest set of wheels used to consist of 18-inch rims, but now the base car rolls on 19s, while the rest of the expansive range sits on 20s. 

The inside has seen some changes, too, but the appearance of things in the cabin isn’t the focal point - its the usability of the technology that's the big change. 

Oh, but I should tell you there are now 64 ambient lighting colours to choose from, which is up from seven, and now you can also set the lighting in three different zones - so theoretically you can have blue, orange and green areas of the cockpit, if you’re gross.

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.

If you’re buying a Mercedes-Benz S-Class there’s a good chance you’re more interested in the back seat than the front: you could be buying it for a business, or you could like to be driven around - and there are definitely worse places you could be.

We would suggest, though, that the best place you could be if that’s your caper is in the back of a long-wheelbase S-Class model, which has extra legroom. 

And if you happen to be in a LWB model with the 'Business Class Package', you’ll enjoy two individual rear seats rather than a three-seat bench, folding tables for your bento box or laptop, and an ‘executive seat’ on the passenger side that features a foot rest and allows you to slide the front seat forward to liberate more room. Deluxe. 

No matter if you are in one of the stretched models demarcated as such by the ‘L’ suffix or not, you will enjoy excellent seat comfort and good head- and shoulder-room. Legroom in the regular models isn’t as plentiful as you might expect: much more affordable cars like the Hyundai Sonata give the S-Class a run for its money in that regard.

There are good storage options for odds and ends, with the back seat featuring a fold-down armrest with pop-out cupholders and a storage box, as well as map pockets - and the boot space varies depending on the model, but the S 350 d has a 510-litre cargo capacity (VDA). All four doors have bottle holsters, and a bit of extra room besides. Of course there are rear-seat air-vents, and if you’re kids are lucky enough to ride around in a S-Class, the two ISOFIX/three top-tether points will be welcome.

Up front there are two cupholders between the seats, and a new wireless phone charger in the centre console (Qi compatible phones only). There are two USB ports as standard in most models, while models with the rear seat entertainment package fitted get rear USBs. 

The huge screen that runs across two-thirds of the dashboard has seen the noticeable join marker removed for this update, with the monitors being upgraded to a higher resolution and the graphics have been reworked, too. The codpiece-style controller of the Comand media interface remains, and while it still isn’t as simple as other controllers, it is reasonably easy to get used to. 

So … what about Beyonce? 

She comes in as part of the Energizing Comfort Control system, which is standard in some models and a $1400 option in those that don’t have it fitted. 

Essentially it allows you to choose between different set moods: 'Joy', 'Freshness', 'Vitality', 'Warmth', 'Comfort' and 'Training', the latter of which offers three different stretching/exercise programs that last for 10 minutes to stop fatigue. The instructions are given by voice over the sound system.

Each of the moods will adjust the temperature and ventilation (the Freshness setting offers ‘gusts’ of fresh air as if you’re at the beach!), ambient lighting, air fragrance and intensity, and the massage function for the seats. And the music bit - there are predefined songs the system can cue up to suit the mood, or it can identify songs on a hard-drive or USB that suit the programs by analysing the tempo of the tune. Amazing, right?

The new steering wheel looks a lot sportier than the one in the pre-update car, and it has finally done away with the awkward cruise control stalk in favour of steering wheel buttons for the adaptive cruise control system.

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 big news for the majority of S-Class buyers is the new engine in the S 350d, which is a 2.9-litre in-line six-cylinder turbo-diesel with 210kW of power and 600Nm of torque. It has a nine-speed automatic and is rear-wheel drive (RWD).

That same diesel engine is wicked up in the S 400d L, with that model churning out 250kW and 700Nm, and remains rear-drive with a nine-speed auto.

The petrol model range is opened by the S 450 L with a 3.0-litre six-cylinder twin-turbo mill producing 270kW/520Nm. Again, nine-speed auto, RWD.

The S 560 and S 560L run the same 4.0-litre twin-turbo V8 petrol with 345kW of power and 700Nm of torque. Nine-speed auto, rear-drive - naturally!

The AMG-fettled S 63 has a thumping twin-turbo 4.0-litre V8 petrol engine with 450kW and 900Nm, with a nine-speed MCT multi-clutch auto and - you guessed it - RWD.

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 diesel models are - unsurprisingly - the most frugal in the range, with the entry-level S 350 d using a claimed 5.4 litres per 100km across a range of disciplines.

The S 400 d L - which uses a higher-output version of the same diesel drivetrain as the model above - uses only a minuscule amount more: its claim is 5.5L/100km. 

The most frugal of the petrols is the S 450 L, with its six-pot petrol twin-turbo using a claimed 8.4L/100km.

Every model has stop-start - including the AMG - and the V8 petrols also feature cylinder deactivation when in 'Eco' mode.

That cylinder deactivation system helps the S 560 achieve an incredibly low claimed consumption of 8.5L/100km. So does the longer, slightly heavier S 560 L.

The higher-out Mercedes-AMG S 63 L uses 9.0L/100km, according to its claim. Amazing for the outputs of the engine.

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.

Smooth. It wasn’t even because I’d chosen the Energizing Comfort Control mood to elicit that vibe. It’s smooth - and so it should be.

Whether it’s the near-silent new six-cylinder diesel, which hauls the near two-tonne sedan along with less fuss than a medical centre receptionist dealing with a room full of coughing patients. There is no fuss. You just hand over control to the engine, and trust it will get you where you need to be.

The V8 petrol in the S 560 also has a bit of a silent killer vibe to it. There’s perhaps not as much noise as a V8 fan might want, but the mumbo is there, and in both cars the gearshifts are sublimely timed and super smooth.

Admittedly, the stiff-sided run-flat tyres on both the 19- and 20-inch wheels can exhibit a slight terseness over sharp edges, but when it comes to rolling over pockmarked surfaces or rougher country backroads, the ride offered up by the air suspension with variable dampers is superb. Put it in Sport mode and it stiffens up to the degree you’d expect, but Comfort is no doubt the best place to be.

The steering is super light but accurate, meaning it’s easier than you’d think to pilot this behemoth of a sedan through corners. The grip on offer is excellent, too, even if traction can be an issue - I had a full couple of seconds of strobe light action from the traction control light when I buried the throttle in the S 560. 

I didn’t get a chance to drive the six-cylinder petrol S 450 L, or the S 400 d L. And, I’m really sad to report, there was no opportunity to drive the AMG S 63 L, either. 

But the overall feeling of the updated range is that it remains a deluxe and delightful limousine - whether you have the good fortune of being in the driver’s seat or not.

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-Benz offers a standard three-year/unlimited kilometre warranty.

Servicing is due every 12 months or 25,000km on all engines except AMG drivetrains, which require servicing every year or 20,000km. 

Mercedes-Benz has a (pricey!) capped-price servicing plan. The standard diesel and petrol models in the S-Class range cost $596 for the first service, and $1192 for the second and third visits. The costs for the sole AMG model is $736 for the first service, then the second and third visits are $1472 per.

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.
