MG MGS5 EV vs Isuzu MU-X

What's the difference?

Benchmark is a big word. But I’ve been testing cars long enough to know when and where to use it, and if my motoring instincts are correct the MG S5 EV could be the new benchmark for budget small electric SUVs.

Still we’ve only driven one grade - the Essence with the bigger 62kWh battery. We need to get the other grades into the garage to test them too, but on first impressions the MG S5 is outstanding for price, practicality, styling, ownership, and the way it drives.

The MU-X has plenty of appeal as a daily driver – dependable and it’s a proven 4WD wagon.

Does the 2.2-litre engine add anything substantial to the mix?

Well, it's better than the 1.9-litre, that's for sure, and there's a lot to like about this MU-X in terms of its off-road capability, driver-assist tech, standard features and all-round driveability. And, while the LS-T lacks the top-shelf polish of the X-Terrain, it’s still an appealing potential purchase.

But the 3.0-litre option is better because while the 2.2L is very effective off-road and general day-to-day driving, it lacks grunt and has to work that much harder and is that much noisier under load than the 3.0-litre in most driving scenarios, including 4WDing.

The MG S5 EV is a completely new car. Unlike the ZS EV which was a combustion car that was later turned into an EV, the S5 EV was designed from the start and built as an electric vehicle and that’s super important for everything from space to how it drives.

The S5 EV is a bigger car than the ZS EV. It’s 153mm longer and 40mm wider and it shares the same underpinnings as the excellent MG4 hatch.

The S5 EV looks a bit like the MG4 but an SUV version and I think the styling is a massive improvement over the ZS EV. This thing looks snatched with its sleeker shape and a smooth modern face, the blade-like LED running lights sitting atop the headlights and I really like the treatment to the tail-lights as well and the way the boot lid flicks up into a little integrated spoiler.

It's a far more refined, mature and prestigious look to the ZS EV. And while we're being completely subjective here I also think it's better looking and more refined than the BYD Atto 3 and Chery E5.

That same refinement and modernity is everywhere in the superb cabin from the clean dash design and door trims, to the steering wheel and floating centre console.

In terms of appearance, the MU-X remains largely unchanged from the most recent iteration. And that’s a good thing. It’s blocky enough to be recognisable but sleek enough to remain inoffensive. Worth noting the door handles, window trims, front fender accents, roof rails, and side steps on the LS-T are gloss black.

Inside, nothing much has changed (other than a newly-introduced idle start/stop button) and, as such, the MU-X retains a low-key familiarity that makes it a comfortable space. Generally, design-wise, the MU-X more than holds its own against the likes of the Toyota LandCruiser Prado and Ford Everest.

The MG S5 EV’s practicality is also outstanding and while it’s early days, it could be the new benchmark for the class. It's a spacious cabin with superb ergonomics and excellent storage.

Even as a taller person (I’m 189cm) there was plenty of elbow, shoulder and legroom for me as a driver and also to sit behind my driving position in the second row.

Storage is excellent with giant bottle holders in all the doors, stowage under the floating centre console, four cupholders and a flat space for your phone which also is a wireless charger on the Essence.

It’s such an ergonomic and practical cabin even the buttons are practical. There’s a volume dial, and physical buttons and switches for the climate control switch, not screen buttons.

And then there’s the boot, at 453 litres it’s about 10 litres bigger than the ZS EV’s cargo capacity. It's also 10L larger than the Atto 3 and a lot bigger than the Chery E5’s boot.

The interior has a familiar and practical feel about it and the cabin is an easy space in which to become comfortable. Controls are easy to locate and operate and charging options are numerous – a mix of USB-A, USB-C (front and second row) and 12V.

Storage places include recesses for the bits and pieces from your pockets, a deep-ish centre console, as well as dual cupholders up front, cupholders in the rear fold-down centre armrest and bottle holders in the doors. There are also cupholders either side of the third row.

The MU-X has physical-button options to activate some functions (including to switch on the audio system, to adjust volume and access sat nav).

Seats are comfortable and supportive through all three rows – yes, even the third row is roomy enough to prevent whining from whoever is back there.

My camera guru/photographer/sergeant-at-arms, Glen Sullivan, reminded me that the third-row seats don’t have ISOFIX or top-tether points for child seats. Thanks, mate.

The cargo area is 311 litres with all three rows in use, 1119L with the third row flat and 2138L with the second and third rows stowed away.

The rear cargo area has a cargo cover, tie-down points, a 12V power outlet, a storage space under the rear cargo area floor and a space for tools inside the driver’s side rear cargo wall. The MU-X’s full-size spare (bravo!) is attached to its undercarriage.

The new MU-X with a 2.2-litre, four-cylinder, turbo-diesel engine is available with a 4×2 or 4×4 drivetrain in several variants. Don’t worry, the 3.0-litre is still in the line-up.

Our test vehicle has the 2.2L and, it is priced at $71,400 before on-road costs.

Standard features include a 9.0-inch multimedia touchscreen system with sat-nav, wireless Apple CarPlay and Android Auto, an eight-speaker sound system, eight-way power-adjustable driver’s seat (four-way power-adjustable front passenger seat), heated front seats, a 7.0-inch driver display and 20-inch alloy wheels shod won 265/60R20 Bridgestone 684II HT tyres.

It also has white ambient interior lighting, remote engine start, rear privacy glass, power-folding and heated door mirrors (with side cameras) finished in gloss black, and leather-accented upholstery with grey stitching and synthetic leather on the door trims and centre console.

Exterior paint choices on the MU-X LS-T include 'Mineral White', 'Basalt Black mica', 'Moonstone White pearl', 'Magnetic Red mica', 'Neptune Blue mica', 'Mercury Silver metallic', and 'Obsidian Grey mica'. Anything other than standard Mineral White costs an extra $695.

The MG S5 EV has one electric motor driving the rear wheels and it has an output of 125kW and 250Nm. That’s plenty of grunt to move this electric car quickly and instantly in a way that feels controllable and smooth. 

While front-wheel-drive cars are absolutely fine, rear-wheel drive tends to offer more engagement and feel, and that's an added bonus for the S5 EV.

This MU-X has a 2.2-litre, four-cylinder, turbo-diesel engine, producing 120kW at 3600rpm and 400Nm between 1600-2400rpm and it’s matched to an eight-speed automatic transmission.

Worth noting the 3.0L MU-X has a six-speed auto and produces 140kW (at 3600rpm) and 450Nm (1600-2600rpm) while the outgoing 1.9L MU-X has a six-speed auto and produces 110kW (3600rpm) and 350Nm (1800-2600rpm).

While the 3.0-litre has always been unstressed in most driving scenarios – even low-range 4WDing – the 2.2-litre feels underpowered. More about that in the ‘Driving’ section below.

The MU-X has a part-time 4WD system which includes a dual-range transfer case (with high- and low-range 4WD) and a rear diff-lock. The driver is able to shift from 2H (two-wheel drive, high-range) to 4H (4WD high-range) while on the move up to speeds of 100km/h. The diff-lock may only be engaged when the vehicle is in 4L (4WD low-range).

The MU-X also has a switchable terrain mode system which tweaks the engine, transmission and traction control to suit the driving conditions. 'Rough Terrain' mode, like a steroids-enhanced off-road traction control, is king of these modes when you’re off the bitumin.

The MG S5 EV’s energy consumption varies depending on the grade and battery size.

The most efficient in the range is the entry grade Excite with the 49kWh battery with MG saying on a combination of open and urban roads it should use 16.6kWh/100km (WLPT). The biggest energy user in the range is the Essence grade with the 62kWh battery with 17.1kWh/100km.

As for the range, this varies from 335km in the 49kWh Essence to 430km in the 62kWh Excite.

Official combined cycle (urban/extra-urban) fuel consumption for this MU-X is 6.7L/100km. The 1.9L MU-X offers 7.4L/100km while the 3.0L offers 7.6L/100km.

Actual fuel consumption on this test was 8.7L/100km.

The MU-X has an 80-litre fuel tank, so, going by that on-test fuel consumption figure, you should be able to get a driving range of about 920km. But remember, your fuel consumption may be completely different to mine because chances are you'll have friends, family pets, sporting equipment, camping gear, the whole kit and caboodle on board. I've only been carrying vehicle recovery gear, MaxTrax, and a first-aid kit, so I haven't had a huge amount of weight on board.

The MG S5 EV is outstanding to drive for an electric vehicle at this affordable price point. Again, I’m going to put it out there and suggest it could be the new benchmark for the more affordable end of the small electric SUV segment. Kia's EV3 is also a winner on the road, but it's quite a bit pricier than the MG.

I was never a fan of the way the ZS EV drove, from its seating position to ride and handling. But the MG S5 EV is completely different to pilot. It’s excellent.

This car feels so composed on the road, the body control is excellent, the steering is well weighted and direct, the visibility is excellent and the pedal feel under my feet is solid, too. And all of that is combined with an electric motor that makes the perfect amount of power.

Add to all this the rear-wheel-drive component and the MG S5 EV is not just easy to drive but engaging as well.

Before we launch into the off-roading section of this test, it’s worth noting the MU-X has always been decent on-road; composed, reasonably refined (for a 4WD wagon, anyway) and comfortable. And thankfully, with the 2.2-litre engine, not all of those characteristics have been thrown out the window.

It is quite noisy, especially under pressure when you have to do some heavy acceleration or when you have a bit of gear on board. When it has to work that bit harder than it usually does, it can become quite noisy. Admittedly, the 3.0-litre MU-X is also quite gruff, but there's an edge to the roughness in the 2.2-litre that is very noticeable on road.

This MU-X is quite sluggish off the mark, exhibiting a disconcerting lag under heavy throttle from a standing-start. And it’s far from the most dynamic vehicle to drive. But it has a tractability about it that manages to mostly negate these flaws.

Otherwise, the new eight-speed auto deserves credit as it’s slick and smooth in application and feels right at home in this wagon.

Now to off-roading. The MU-X is still very capable. In fact, even with the 2.2-litre engine, it remains one of the better-performing 4WD wagons straight out of the dealership, in terms of pure off-road capability.

The 3.0-litre MU-X is not the torquiest in this segment, but it offers ample pulling power available across a wide rev range – count on peak torque between 1600rpm and 2400rpm – and it delivers that pulling power in an even-handed fashion. The 2.2-litre MU-X has to work harder than its stablemate, and it’s noisier and harsher.

However, those characteristics don’t take away from how effective this MU-X is because it offers impressive off-road performance. It still has a decent amount of low- and mid-range torque, which makes dirt-road cruising and low-speed 4WDing easy.

The MU-X has part-time 4WD with high- and low-range 4WD gearing, a rear diff lock and overall it retains all of that off-road capability the 3.0-litre MU-X has been renowned for – so you don't lose any efficacy there.

The line-up’s off-road traction control system, which once was a bit patchy in its effectiveness, has gone through a couple of phases and it’s been recalibrated/tweaked over the years and it is much better now.

Of course, the MU-X also has Isuzu’s much-vaunted Rough Terrain mode (a form of early-acting off-road traction control which converts lost grip into torque for the wheels with grip), and it is smooth and effective, giving the driver better overall control in challenging terrain.

Some of this MU-X’s listed off-road angles appear shallower than the 3.0-litre MU-X’s – approach: 23.9 (3.0L = 29.2), departure: 26.4 (3.0L = 26.4) and ramp-over: 19.6 (3.0L = 23.1) – but, even if that is the case, it has very similar driving characteristics in low-speed, low-range four-wheel driving to its 3.0-litre stablemate.

If you drive with control and consideration, you shouldn't have any trouble tackling light to moderate 4WDing in this MU-X. It could even, if push comes to shove, handle challenges that may be considered by some to be on the edge of hard-core 4WDing – for a showroom-standard 4WD wagon anyway.

Ground clearance is 235mm and wading depth is 800mm, so there’s an adequate amount of clearance to work.

The MU-X – with a turning circle of 11.6m and a kerb weight of 2130kg (3.0L = 2185kg) – feels quite nimble on bush tracks.

This wagon’s wheel travel – how far the axle can move up and down relative to the chassis – has more than an adequate amount of flex, stretching its tyres close, if not all the way, to the dirt.

A noticeable trade-off is its 20-inch wheel-and-tyre combination, which is best suited to sealed surfaces and so are far from ideal for dirt-track touring. There’s an easy remedy, though. Buy a set of decent all-terrain tyres on 17- or 18-inch rims to replace the showroom-standard 265/50R20 Highway-Terrain tyres. If you are using your MU-X, avoid dropping pressures too much because you’ll risk sidewall pinches and punctures on these low-profile road tyres.

In terms of packability: the 2.2L MU-X has a listed payload of 670kg, whereas the 3.0L version offers 615kg.

The 2.2L MU-X can legally tow 750kg (unbraked trailer) and 3500kg (braked), so theoretically you can tow the same load as a 3.0-litre MU-X. But, as mentioned, the 2.2-litre engine feels underpowered, even in general day-to-day driving, so with a load and/or towing that’s an added burden.

For reference, the 2.2L MU-X has a listed gross vehicle mass of 2800kg and gross combined mass of 5900kg.

The MU-X has the maximum five-star ANCAP safety rating from testing in July 2022.

Standard safety features include eight airbags - dual front, dual front side, dual full-length curtain, front knee and centre (far-side) - and a comprehensive suite of driver-assist tech including AEB, adaptive cruise control, lane-keep assist, lane departure warning, a digital reversing camera and a tyre-pressure monitoring system.

Remember, the third-row seats do not have ISOFIX or top-tether points for child seats.

The MG S5 EV is covered by MG’s 10-year 250,000 kilometre warranty. And that includes the battery. Regular families though do about 10,000km a year or 20,000km maximum, so this warranty offers excellent coverage for them.

The MU-X has a six-year/150,000km warranty and seven years of roadside assistance. Unlimited km in the warranty would be welcome.

Service intervals are scheduled for every 12 months or 15,000km, whichever occurs soonest.

Capped price servicing covers the first five scheduled services for MY24 and later vehicle models (up to 5 years/75,000km – whichever occurs first) – at a flat price of $469 for each service.

Isuzu Ute Australia has a nationwide network of more than 160 dealer sites.
