Isuzu MU-X vs BYD Atto 3

What's the difference?

So, engine aside, not much new for the 2024 MU-X, but I can confidently say this: if you’re not towing big loads all of the time, then the 1.9-litre turbo-diesel won’t just save you cash at the dealership, but at the service station, too.

Like its interior design, you may find the BYD Atto 3 Extended Range to be a divisive experience. On the one hand, I like how well it handles in the city and the playful design.

The car feels roomy and the boot is a good size but this is not an open-roader. If you plan on doing weekend escapes in this, think again. This is a car that likes the city and will complain if you venture outside of its limits.

I do like the affordable price tag, considering it's an EV, and the features you get but that open-road ride needs improvement.

If you like the look of the 2023 Isuzu MU-X, then boy have I got good news for you, because the changes to the 2024 model occur under the bonnet, and nowhere else, really. That means you get the same simple, boxy exterior design, which emphasises capability over fanciness.

Yes, the MU-X design is more dependable than daring, but I reckon it works, with the three-row SUV cutting a fairly handsome figure, even if it is yet to receive the design tweaks just rolled out on the updated Isuzu D-Max.

Inside, though, it definitely presents as a little utilitarian, with some plastics that feel like they could survive a nuclear blast, and the 7.0- and 9.0-inch central screens both feel a little underwhelming by modern standards.

It all feels very comfortable and hard-wearing though, which is probably every bit as important, given the MU-X’s target market.

The exterior is quite understated and you might not necessarily pick this out as being an EV at first glance. It has a nice-looking profile that immediately identifies it as a medium SUV and it should appeal to owners who want something that looks smart but won't stand out on the road.

There are some cool design elements like the textured chrome panelling on the C-pillar and bonnet, which enhances the BYD badging. The LED strip lighting for the daytime running lights and tail-lights do lean more towards the futuristic vibe that EVs usually showcase.

The interior is where the fun has been had but it's likely to be divisive. The three-tone synthetic leather trims have some pizzazz but not everyone will like the black, white and navy combo.

That said, I like the contrasting red detailing on the piping, stitching and elastic door pocket cords.

The curvy dashboard features a white panel that looks like a flexed muscle (and not in a Magic Mike way!). The air vents remind me of the Echo Base on planet Hoth in Star Wars, which will always be cool to me, but my husband thinks they look like stacked drink coasters.

The rotary door handles are a total vibe and the adjustable ambient lighting manages to tie it all together but while it's great that BYD has had fun in here, not all of it lands for me.

Practicality has always been a sizeable MU-X perk, regardless of the engine. 

That starts with seven seats, and a back row where actual full-size humans can spend time — and there are not many three-row SUVs you can say that about.

I’m 175cm tall and while I wouldn’t pick row three as my first choice, I’d happily sit back there for short hops.

The middle row, too, is pretty spacious, though it is lacking in a few creature comforts, with just the air-con vents (but no temp controls) and a couple of USB ports to keep you company.

And remember when I said the brand was promising the 1.9-litre engine wouldn’t cost much in terms of capability? Well, Isuzu says the braked towing capacity for models fitted with the smaller engine is 3000kg, while the payload figure increases — now up to 735kg — mostly because the new engine is about 70 kilos lighter. Models fitted with the 3.0-litre turbo-diesel are still rated to tow 3.5-tonne. 

The MU-X stretches 4850mm in length, 1870mm in width and 1815mm in height and it sits on a 2855mm wheelbase, which means while there’s plenty of cabin space it’s not too ridiculous to park.

You’ll find 311 litres of boot space with all three rows in place, growing to 1119 litres with the second row folded flat and 2138 litres with just the front two seats in action.

Every MU-X model will offer at least 800mm in wading depth and 230mm ground clearance, too.

As soon as you slide in, you're pleasantly surprised by how roomy it feels. I have plenty of leg- and headroom in both rows for my 168cm (5'6") height. Which is impressive given the massive panoramic sunroof.

Both front seats are heated and electric with the driver's side sporting a six-way adjustment, while the passenger is only four-way.

However, due to the sports-like seat style, the headrests are fixed which may annoy taller drivers. There is no lumbar support either and, trust me, you'll notice it on a longer trip. Ouch.

Up front, the individual storage is good with an extra deep middle console and a shelf that sits underneath the 'e-shifter'. Plus, there is a glove box and a handy utility tray that houses the wireless charging pad.

The back seat is very comfortable and individual storage is adequate for the odd passenger with two map pockets and four device pockets available.

The drink bottle holders and cupholders (two in each row) are a tad skinny, though, and two regular-sized takeaway coffee cups will overlap at the lid.

Charging options are good throughout with each row getting an USB-A and USB-C port, the front also gets a 12-volt socket.

However, the ports are hidden in the shelf of the middle console and I'd prefer to have the media port up top as it's wired Apple CarPlay and Android Auto.

The 12.8-inch touchscreen multimedia system looks massive on the pared back dashboard and it rotates, allowing you to choose portrait or landscape mode. However, this function is disabled while using Apple CarPlay.

The system is pretty simple to use and the graphics are clear but a lot of functions are buried in sub-menus. Like the heated seat function. I honestly kept forgetting it had them.

I like to drive with the headlights on, as a defensive driving technique, but that dims the screen during the day so much you can't really see it.

The Dirac sound system with eight speakers is sufficient but I noticed the sound quality on my calls was a bit tinny.

The 5.0-inch digital instrument panel's positioning on the steering wheel means you don't miss having a head-up display but the alignment is off by a millimetre or so. Just enough to annoy someone with mild OCD.

The boot space is the highlight for me, though, with its 440L of capacity. You can bump that up to 1340L with the rear seats folded and the rear seats have a 40/60 split-fold.

You'll be making do with a puncture repair kit as there isn't a spare tyre but the powered tailgate was super handy this week on my grocery run.

Curiously, there is no 'frunk' storage, despite there being plenty of room for one.

There's something appealing about BYD's simple and straightforward marketing and purchasing strategy - what you see, is what you get.

There are only two models to choose from, the Standard Range and, our model, the Extended Range. As the name suggests, our model has the longer driving range but there's not that much difference in the specifications between the two outside of that.

One colour - 'Ski White' - is no cost, while 'Parkour Red', 'Surf Blue', 'Boulder Grey' and 'Forest Green' cost $700 extra.

Our model will now cost $51,011 to purchase (before on-road costs), that's a $3630 price hike since the start of the year! Even with the new price, it's more affordable than its nearest rivals with the MG priced at $55,990 and the Leaf e+ at $61,490.

However, you do get a decent number of features for your cash, like heated front seats, electric front seats, a panoramic sunroof, synthetic three-tone leather trims, adjustable ambient lighting, wired Apple CarPlay and Android Auto, and some decent tech (more on that later).

All external lights are LEDs, with headlights having an automatic function and there are two levels of regenerative braking to choose from.

There are some great practical features, too, like a darkened headliner, powered tailgate and 'lock charging port' function (in case you need to leave you car while it's on charge).

Let’s focus on the new engine option here, with the 1.9-litre turbo-diesel delivering 110kW and 350Nm. They don’t sound like massive numbers, but Isuzu makes the point that the torque delivery is wide, with maximum grunt available from 1800rpm to 2600rpm, and 300Nm available from 1550rpm to 3700rpm, meaning there’s power there when you need it.

The new engine pairs with a six-speed Aisin tramsission and delivers power to two or all four wheels.

The Atto 3 Extended Range is a full EV with a single motor powered by a 60.48kWh lithium-ion blade battery. It is a front-wheel drive and has a maximum power output of 150kW and 310Nm of torque.

So, it’s not the most powerful on the market but will certainly get you from A to B with ease and you can go from 0-100km/h in just 7.3 seconds.

Another perk of the smaller engine is a smaller fuel bill, with the 1.9-litre turbo-diesel promising to drink 7.4L/100km on the combined cycle - almost a litre less than the 3.0-litre 4x4 model, which is more like 8.3L/100km. 

Emissions drop, too, with the smaller engine rated at 196g/km of C02 combined, compared with 220g/km on for the 3.0-litre 4x4 model.

Impact on the hip pocket? Well, fewer trips to the service station for one. Isuzu says the 80-litre fuel tank should deliver almost 1100km of driving between refills.

Let’s talk charging. The Atto 3 has a Type 2 Combo CCS charging port and the on-board DC charger has up to 80kW of capacity.

What does that mean? Well, if you were to plug it in at home on a 7.0kW AC charger, you'd be able to go from flat to a full charge in roughly 10 hours.

Plug it into a 50kW fast charger, and you'd see that time drop to around one hour to get from 10 to 80 per cent charge. However, that capacity means it can't accept the faster 350kW charging speeds on ultra-fast chargers.

The official energy consumption is 16kWh/100km and my on-board figure was 14.7kWh.

It has an official driving range of 480km NEDC (420km WLTP), which is better than some on the market but I got major range anxiety this week!

It feels like it chews through its power. Since it's school holidays, I’ve been doing mostly longer open-road drives and have had to charge it three times already! Over three road trips, I've averaged a little over 200km of driving and saw my percentage go from 100 down to an average of 34 per cent at the end of each trip. 

First things first, you can absolutely tow with the smaller MU-X engine. In fact, we attached a load weighing close to its 3.0-tonne maximum and the Isuzu just hunkered down and got to work.

It must be said, though, it’s nowhere near as effortless as when you have the bigger 3.0-litre turbo-diesel engine up front, which dispatches heavy loads clinically and easily.

The smaller option has to try harder and rev higher, and while it’s easy enough on downhill runs or flats, it’s noticeably slower when heading up hill.

It does demand the question of how often you’ll be attaching close to its rated maximum on the towball, though. If it’s often, the bigger engine is definitely for you. But if it’s occasionally, or your tow loads are lighter, you can definitely make do with the 1.9-litre option.

On the road, the 1.9-litre engine’s power delivery is actually pretty well suited to the MU-X. It’s not fast, of course, but the width of the torque band helps deliver grunt when you need it (to a point) especially in the low-end, and I reckon the whole experience is a bit smoother and quieter than with the bigger engine, too.

You are missing some of that effortless grunt, of course, and you still can’t escape the usual diesel noise that permeates the cabin, but the lower fuel use for lower power feels like a fairly decent trade. 

It won’t be for everyone, and cross-country travellers and towers will no doubt go for the bigger unit, but for everyone else the 1.9-litre is a pretty sensible option.

The driving lets this down for me. It's not as zippy as other EVs I've sampled and can even feel a bit sluggish when you accelerate from a full stop. However, it has enough kick for open-road driving, if you're desperate.

Desperate is the key word, though, because this is a total city-slicker. Around town, it handles itself well in tight streets and corners (that 11m turning circle is a charm) but isn't as confidently placed on the road at higher speeds.

And if you happen to be driving on the open-road on a blustery day, it's no fun at all. It shifts and squirms in the lane, with the cabin noise rising to din levels.

Ride comfort is generally good with suspension that feels cushioned but not floaty around the city. Different story on the open-road!

The controls and e-shifter are all well-placed in the middle console but I'd prefer the start-button to be located somewhere else. I mistook it for the ‘Park’ button a few times, which annoyed me.

The regenerative braking can be adjusted to two levels, low and high. Even on the highest setting, it doesn’t have a big physical presence but there's enough to know it's working.

The Atto 3 earns back a couple of points for being stupidly easy to park. The 360-degree view camera system is super clear and I didn’t have to be too choosy with car spaces either because of its size.

This has a good list of safety features coming as standard, like blind-spot monitoring, lane departure alert, lane keeping aids, rear cross-traffic alert and braking, adaptive cruise control, traffic sign recognition, 360-degree view camera system, as well as front and rear parking sensors.

It has autonomous emergency braking with forward collision warning and features car, pedestrian, cyclist and junction turning assistance. It's operational from 4.0-85km/h (up to 150km/h for car detection).

The Atto 3 was awarded a maximum five-star ANCAP safety rating in 2022 and has seven airbags, including a front centre airbag.

If you have a couple of kids, you’ll like the ISOFIX child seat mounts on the rear outboard seats and three top tethers, but two seats will fit best. 

Curiously, there is evidence of ISOFIX mounts on the front passenger seat which need to be removed for our market, instead of just being 'disabled'.

Every Isuzu MU-X model gets a six-year, 150,000km warranty, as well as five years of capped price servicing, and up two seven years of roadside assistant. 

The service are 12 months or 15,000km, and each service costs $449 per year, or a total $2245 over five years.

BYD backtracked from its original warranty launch offer of seven years/unlimited km and the Atto 3 now comes with a six-year/150,000km main warranty.

But the battery has an eight-year/160,000km warranty, which is more in line with the market.

You can choose between two servicing plans – 'Light’ for those who do under 12,000km per year and a ‘Standard’ plan for those who do more. 

Given my open-road and charging experience, I'd say it's a good bet you'll be on the light plan.

On the light plan, services are capped at $189 per year for five-years or up to 60,000km – whichever occurs first.

On the standard plan, which spans eight-years or up to 160,000km, you can expect to pay an average of $299 per service. 

Both plans are fairly affordable but the recommended servicing intervals are every 12 months/20,000 which is a term you often see on a fuel-based car, not an EV.
