Jaecoo J5 vs Mercedes-Benz E400

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.

A convertible that doesn't feel like one when the roof is in place is no easy task to build, but it's one Merc's engineers have pulled off with the E400 4Matic Cabriolet. Effortless power, a tonne of technology and a comfy, leather-wrapped cabin all make Merc's drop-top E-Class a strong proposition.

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.

Elegance. That's the word that springs to mind when you first clamp eyes on the E400 Cabriolet. While the Coupe version has a crouched-over sportiness about its exterior design, the convertible is all about big and boat-like proportions, especially with the fabric roof opened.

Like nearly all drop-tops, the E400 looks best with the cabin open to the elements, and the side profile especially paints a picture of well-heeled wafting, with only the AMG alloys and body styling hinting at the performance on offer under the bonnet.

Inside, expect perfectly executed modern luxury, with soft leather seats, touchpoints that melt under the fingers and a sprinkling of woodgrain trim. All of which feel like old-world luxury, nicely juxtaposed by the huge twin-screen display that dominates the dash.

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.

It's a two-door, four-seat convertible, so practicality isn't at the very top of its list of strengths.

That said, life is peachy for upfront riders, both of whom will travel in spacious luxury. There are two cupholders hidden beneath a woodgrain cover underneath the climate controls - also home to a power outlet - as well as a clever double-hinged central storage bin that can be opened by either the passenger or driver, and which opens to reveal two USB points.

There's room in the doors for bottles, too, and the entertainment system can be controlled via a touchpad controller mounted above the traditional click wheel - although, to be honest, using it is harder and more time consuming than simply pretending it doesn't exist.

Climbing into the back (and we mean climb - there are no rear doors) is made easier by the fact you can fold and slide the front seats automatically by pulling a lever mounted near the headrest. Once there, though, you'll find space is a little tighter, and you feel weirdly cocooned, owing to the huge raised tunnel that runs through the middle of the cabin, and the low roof line.

There are two cupholders that live in the space where the middle seat would normally go, and there's a little bottle-holder cubby to the left of both backseat riders. There are air vents back there, too, but no temperature controls.

The front doors are huge and really very heavy, requiring considerable heft to open them.

The boot space is predictably a little limited, with 385 litres on offer. There's also a little flip-down separator, which shows you how much room the roof will need to come down, reducing boot space to 310 litres. Speaking of which, the soft-top can be lowered in just 20 seconds, and at speeds up to 50km/h.

One practicality quirk, though. The front (and only) doors are huge and really very heavy, requiring considerable heft to open them, especially if you're parked on a slight angle. Honestly, I was reduced to kind of pushing them open with my foot at times.

At $157,400, the Cabriolet is the most expensive model in the E400 family, and is roughly $20k more than the sedan and $10k more than the coupe variants.

That money buys you a comprehensively kitted-out ride - as it really should - with the E400 Cabriolet arriving with 20-inch AMG alloys, LED headlights (made up of 84 LEDs) with high-beam assist, proximity unlocking with push-button start, air suspension and Merc's AIRCAP - a lip above the windscreen that's designed to push air up and over the cabin when the roof is down.

Inside, you'll find leather seats, dual-zone climate control and the clever 'AirScarf' system, which pumps hot air onto your neck when the roof is down (and it's cold out). You'll also nab heated front seats, power windows front and back and an automatic belt feeder, which saves you reaching over your shoulder to get to your seatbelt. So exhausting.

On the tech front, expect a killer 590W, 13-speaker Burmester stereo, controlled by the seriously impressive widescreen cockpit; two 12.3-inch screens that spill from about the centre of the dash all the way to the driver's binnacle, and control everything from navigation to Apple CarPlay and Android Auto.

There's a whole bunch of safety stuff, including semi-autonomous technology, but we'll drill down on that under the Safety sub-heading.

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'.

It's a fabulous engine, this twin-turbocharged V6 - even if it doesn't feel quite so lively in Cabriolet form as it does in the hardtop equivalents.

The 3.0-litre unit produces 245kW/480Nm, sending it to all four wheels via a nine-speed automatic transmission, linked to the standard 4Matic all-wheel drive system.

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.

Mercedes claims 7.4L/100km on the combined cycle (but you can expect to be pushing nine litres in real-world conditions), with emissions pegged at 170g per kilometre of CO2.

The 66-litre tank will only accepts 95RON fuel.

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.

Sure, the E400 Cabriolet can drive itself, but we’re equally pleased to note that it’s still a lot more fun handling the steering duties yourself.

And that is mostly due to that fabulous engine; quiet and effortless at city speeds, rorty and enthusiastic at pace, and genuinely angry with the drive setting switched to their most hardcore Sport+ mode.

We’ve already spent time in the sedan version, and while this Cabriolet is heavier (1935kg vs 1820kg) and slightly slower to 100km/h (5.5sec vs 5.2sec) it doesn’t immediately feel it behind the wheel, with a similar and satisfying lurch into the future when you plant your foot.

But hard charging is not what this car is about, and the E 400 is at its peachy best when rolling about the city or the ‘burbs with the top down, and the warm summer air washing through the cabin.

In its normal drive settings, the steering is light but engaged, and the ride on offer from the standard air suspension is outstanding, cosseting the cabin from all but the very worst road imperfections, while the torque from the V6 serves up effortless, unobtrusive acceleration.

With the roof up, Merc’s designers have done a stellar job of hiding the fact this thing is a convertible at all. It’s a solid-feeling cabin with the fabric roof fastened, and the cabin is quiet and free from wind noise.

There are few cars on the road as overloaded with safety technology as the E400 Cabriolet.

The standard stuff is all there, of course. There's a 360-degree parking camera, as well as nine airbags (dual front, dual pelvic/thorax for front-seat passengers, dual sidebags for rear passengers, dual head bags in the doors and a knee airbag for the driver), rollover protection and tyre-pressure monitoring, as well as braking and traction aids.

But the E400 adds some really clever technology, including Merc's Driving Assistance Package Plus, which adds active lane keeping, blind-spot assist, cross-traffic alert and evasive steering assist.

It's this suite of systems that allows the E400 to navigate freeways autonomously, including changing lanes on demand. At the moment, the system will warn you to keep your hands on the wheel every so often, but you can sense a time when that will no longer be required. And that time is soon.

The E-Class range scored the maximum five-star ANCAP safety rating when crash tested in 2016.

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.

Expect the usual three-year, unlimited-kilometre warranty, with service intervals pegged at 12 months or 25,000km. Mercedes' capped-price servicing scheme limits maintenance costs to $2280 for the first three years of ownership.
