Toyota BZ4X vs MG MGS5 EV

What's the difference?

The Toyota bZ4X base variant is an uncomplicated car to drive. It has some decent features for its grade level and it is plenty big enough for my little family of three but it doesn’t always come out ahead of its rivals.

It would be an easy EV to dip your toes in if you’re wanting something economical to maintain yet able to fit the family. But it's expensive for what it is.

My seven-year old likes the cool looks but has been confused about Mummy is reviewing the same car again.

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.

There’s not much separating the bZ4X from its Subaru twin other than badging and ever-so-slightly different front and rear fascias. The differences are so small only diehard enthusiasts will be able to tell them apart. To me, they look the same on the outside!

The overall look is sporty and fun with lots of pleating in the panelling to give it a futuristic vibe and sharply defined tail-lights for some edginess.

Against our test model's 'Liquid Metal' paintwork the heavy black plastic moulding wrapping around the base of the car doesn't stand out too much but will on a lighter colour.

The internals do differ somewhat and the best change is the more traditional round steering wheel. I prefer the look and feel of it compared to the squared-off shape of its twin's.

The 7.0-inch digital instrument cluster is set a fair way back on the dashboard and looks disjointed from the rest of the tech. The steering wheel also cuts into my vision of the screen and while I could shift my seating position to better accommodate, I'd be compromising my driving comfort to do so. A head-up display would be welcome here.

The dashboard, doors and seats all feature a grey knit-like fabric that looks warm and inviting but the cabin is elevated by synthetic leather trims throughout. Overall, the cabin is quite pleasant but wouldn’t be out of place on a much more affordable car.

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.

The cabin is very spacious with generous leg- and headroom. I have plenty of room for my 168cm (5'6") height but my 183cm (6'0") father was also very comfortable in both rows.

The seats in both rows are well-cushioned and up front, the driver’s side has ample support from the two-way powered lumbar. I also like the way both front seats are heated. You could handle a long trip even as a passenger prince/ss.

Individual storage is less generous than you’d expect for the class given you don’t get a glove box but there are still enough nooks and cubbies for some items and a shelf underneath the console can fit a small handbag.

My seven-year old discovered a secret pocket underneath a removeable box in the middle console where Toyota has stored the manual and logbook.

Up front you also get two cupholders, four drink bottle holders (two in each door) and a handy cubby behind the rotary transmission shifter. In the rear you get map pockets, two cupholders and a device holder in the fold-down armrest and a large drink bottle holder in each door.

No complaints from my kid regarding the amenities in the back and he likes having his own directional air vents and reading lights. But it's the 182mm ground clearance we all love because the bZ4X is super easy to get in and out of. Definitely no grunts in this one!

There's no frunk storage but the boot's 421L capacity will suffice for your bigger grocery run or odd trip but the capacity is lower than some rivals. Underneath the level loading space there's a retractable cargo liner, two cable pouches, a first aid kit and the tyre puncture repair kit. I like the powered tailgate on the base model. I find them handy with a kid in tow.

Technology is well-rounded and upmarket. The 12.3-inch touchscreen multimedia system is responsive and easy to use but the customisations for internal features are a little lacking. The built-in satellite navigation is clear and there is a dedicated Toyota services app, too.

The wireless Apple CarPlay is simple to connect to and I didn't have any dropouts with calls or connections, which is great. There is also wireless connectivity for Android Auto users.

Charging options throughout the car are solid with each row getting two USB-C ports, while the front also features a USB-A port and 12-volt socket. However, there’s no wireless charging pad or V2L (vehicle-to-load) capability which might annoy over long-term use.

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.

There are two grades in the MG S5 EV line-up. The Excite is the entry grade and the Essence is the top-of-the-range grade. Both come with a choice of two batteries - there's the smaller 49kWh battery and a bigger 62kWh battery. Now that you know this, the pricing will make more sense.

The MG S5 EV line-up starts at $40,490 with the entry grade Excite with the 49kWh battery, then steps up to $42,990 for the Essence also with the 49kWh battery. That increases to $44,990 for the Excite with the 62kWh battery and tops out at $47,990 for the Essence with this unit. All prices are drive-away.

Standard features on both the Excite and Essence include LED headlights, LED running lights and LED tail-lights, also standard are alloy wheels - 18-inch ones on the Essence and 17s on the Excite.

Both grades have proximity unlocking single-zone climate control, a 12.8 inch media display digital radio, a four-speaker stereo on the Excite and a six-speaker sound system on the Essence, while both have wireless Apple CarPlay and Android Auto, sat nav and a 10.25-inch instrument cluster.

The Essence has a few extra items the Excite doesn’t get like rear privacy glass, a panoramic glass roof, wireless phone charging, heated front seats and a power driver’s seat.

The bZ4X base variant is a front-wheel drive and has a single electric motor producing 150kW/256Nm - which sounds a bit schlumpy compared to its rivals but its pick up is great and you don’t feel it's underpowered, even when you’re on the open-road.

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.

The official energy consumption figure is 16.9kWh/100km and I averaged 16.1kWh over a mix of urban and open-road driving. The consumption is good and on par with some of its rivals but the official driving range from the large 71.4kWh lithium-ion battery is up to 436km, which is lower than most of its rivals by a good portion.

The bZ4X has a Type 2 CCS charging port which means you can benefit from faster DC charging speeds, up to 150kW. On a 150kW DC system you can go from 0-80 per cent in around 40-minutes.

On a 7.0kW AC charger, you can go from 10-100 per cent in 9.5 hours and that drops to seven hours on an 11kW system. All the bZ4X figures are good enough to avoid the inconvenience zone but aren't as fast as some of its competitors.

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.

You don’t often notice this base model is a front-wheel drive until you accelerate too quickly from a standstill and tlose a bit of traction. Otherwise, power delivery is smooth and while you don’t get a tummy-sucking-sensation when you put your foot down the power satisfies for city and open-road driving.

The steering feels light and there's a fair bit of understeer when tackling winding roads. This made the handling a bit lacklustre at times but it’s not too intrusive in an urban environment. Just remind yourself it’s not a performance EV if you ever start thinking ‘fast and furious’ thoughts.

Ride comfort is very good and I’d attribute that to a well-cushioned suspension set-up. While you notice bumps, you’re not bothered by them, even in the back seat. The cabin is peaceful and quiet most of the time but road noise creeps up a lot at higher speeds.

Visibility is excellent and despite a few little things, like the steering, it’s an uncomplicated car to drive.

The bZ4X isn’t too hard to park because the reversing camera is relatively clear but this grade would benefit from the 360-degree view system which is available on the top-grade model. The 4690mm length, 1860mm width and 1650mm height makes it a happy-go-lucky friend in a small car park.

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.

The MG S5 EV has the maximum five-star ANCAP rating and that’s from 2025 so it is super fresh. That means it has the lot so there’s auto emergency braking (AEB), front cross-traffic alert, rear cross-traffic alert with braking, lane keeping assistance and blind spot warning, adaptive cruise control, intelligent speed limit assist and more.

There's also a driver and front passenger airbag, two side airbags, two curtain airbags and a far side airbag.

For child seats there are two ISOFIX points and three top tether anchor points.

The bZ4X comes with a five-year/unlimited km warranty and the battery is covered by an eight-year or up to 160,000km warranty. Both are usual terms for the class.

There is a five-year or up to 75,000km capped priced servicing plan and annual services cost just $180, which is very competitive.

Servicing intervals are more in line with a fuel-based car at every 12-months or 15,000km, whichever occurs first. 

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.
