BMW M5 vs Mazda MX-30

What's the difference?

Let’s get one thing out of the way: the new M5 is a very good car. Considering the emissions limitations and size increase of its base model, it is an impressive bit of engineering. 

What’s trickier is deciding whether the new car is really better to drive. Less edgy but supremely comfortable and quiet; BMW leaned into the daily usability of the plug-in hybrid M5 rather than amping the petrol-electric system for maximum thrills. And do you know what? That’s fine with me. 

The new M5 still performs on road and track and does an incredible job of hiding its weight (most of the time). Perhaps the G90 is a little more Audi RS6 than F90 in its demeanour but some would argue that’s no bad thing. 

The concept of the BMW M5 is not static, it evolves with the times, and the G90 is no exception. Expect future Competition and CS variants to unlock some extra lunacy. 

Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.

The MX-30 is a tough one to give you a clear verdict on. In summary, though, the math just doesn’t add up. This car is way too expensive and offers next to no range for Australia’s vast intercity distances, essentially resigning buyers to a life within city limits.

On the other hand, I love the design ethos of this little SUV. It’s truly a statement, and it’s rare to find a car that is so committed to its uniqueness. It’s also easily one of the best EVs to drive right now, so those who understand its compromises will no doubt be left with smiles on their faces.

The M5’s raw size is what you notice first. The G90 M5 is a whopping 113mm longer, 67mm wider and 37mm taller than the car it replaces, with the wheelbase stretched 24mm.

It is also the most pumped M5 yet, compared to a 520i it is 70mm chubbier at its flared wheel arches. The ‘M5’ insignia on the C-pillar means you’ll know this is the fast one. 

Presence is not in question, then, but beauty? Not the right word. The G90 makes its predecessors — especially the original ‘E28’ — look demure. 

The cabin layout builds on the concept debuted by the iX electric SUV, with twin integrated screens and focus on technology and minimal buttons. Materials are mostly high quality and feel fitting for the M5’s asking price.

The MX-30 oozes design. I would go so far as to say this car is more focused on being a design statement than it is an SUV (as evidenced by its lack of practicality…) or an EV (as evidenced by its lack of range…).

Mazda’s Kodo design language is already eye-grabbing, so it’s to the MX-30’s credit that it manages to be striking, even against other members of the Mazda family, as it strays from a well-refined formula.

The large grille has been dumped in favour of something much smaller but the 3D effect of the Kodo face still persists. The light clusters adopt their own personality - they're inspired by the Mazda3, arguably, but they stand on their own.

The side profile, squat dimensions, and contrasting panel work (in our car’s case, a matte grey against the brand’s signature ‘Soul Red’) alert you to the fact that the MX-30 is something quite different indeed. And all this is before you notice the fact that it has clamshell rear doors.

Yep, that’s right, the MX-30 reaches into the brand’s history and brings back the outward folding door design once seen on the RX-8 rotary sports coupe. Opening it up is an event, and those doors wow onlookers with their unusual unfurling. Unfortunately, it’s not as smart as it looks, but we’ll get to that in the practicality part of this review.

The inside again blends familiar Mazda themes with entirely new ones. The material design is incredible. For the first time in a long time, I felt like a kid in some kind of tactile science museum, prodding, squeezing, and scratching at this car’s many interior elements to see if they were, in fact, made of the occasionally unbelievable materials they seem to be.

It doesn’t disappoint. Yes, the door cards really have a splash of an odd grey carpet material, very Volvo, the seats are really trimmed in some sort of synthetic leather, the quality grain of which has to be felt to be understood (it's very Mercedes), and the centre console is really made of recycled cork panelling, which is very BMW.

All of this might sound a bit silly (and the cork stuff perhaps is) but along with the stepped centre console design, weird semi-digital dash cluster and familiar bits out of other Mazdas, it is difficult to not enjoy being in such a creative and unusual space.

The commitment to this funky, unusual design, has some major practicality drawbacks, which we’ll take a look at next.

BMW has persevered with its twin-screen, minimal-button approach for its 'Operating System 8.5' in the M5. 

The 14.9-inch central touchscreen is bright, responsive and high resolution but the software remains a little strange. The main interface is classy but when looking for settings to adjust you’re presented with a Windows 95-esque panel of small square touch targets. It’s not intuitive. 

Wirelessly mirroring Apple CarPlay or Android Auto works a treat, at least. Digital climate controls keep temp adjustment persistently on screen and a shortcut to fan speed. The nipple-like vent direction adjustment grows on you, as do the digital vent sliders. 

The 12.3-inch digital driver’s display still doesn’t have the freedom of customisation and clarity of Audi’s interface. 

The M5 has two cupholders, a deep central storage cubby, door bins that swallow two 600mL plastic bottles and twin wireless charging pad that resolutely grips smartphones even under the sort of tummy-churning G-Forces this M5 can manage. 

Setting the M5 apart from the regular sedan is a unique centre console bunching 'M Drive' modes, 'M Hybrid' modes and other shortcut functions together next to the gear toggle and M-engraved crystal 'iDrive' controller.

Comfortable front seats are power adjustable with in/out, up/down lumbar support and have two memory positions. 

The 5096mm long M5’s back seat is very spacious. Headroom is good for those beyond 182cm (six-foot), the bench is extremely supportive, while leg and toe room are adequate.

A fold-down centre armrest has two cupholders and there are USB-C charge ports in the back of each bucket seat for a total of four. 

You can buy an accessory mount that holds tablets or smartphones for rear seat passenger entertainment, too.

When you look in the boot, BMW offering a Touring version of the latest M5 makes even more sense. The load aperture is big but the usable space is narrow; the sides intrude on load space. 

The 466-litre space will make fitting suitcases for an airport run tricky and, even with the 40/60 split-fold rear bench, you will struggle to fit a bike in the back. There’s no spare tyre, either.

Put simply, the MX-30 is about as practical as a sports coupe, which is a feat given it has the footprint and height of an SUV.

It starts with those clamshell doors. Sure, they look amazing, but they’re annoying to open because the handle is on the inside, so you have to open the front doors before you can open the rear ones. At best this costs you time when you’re just trying to load objects, pets, or kids, at worst it makes the rear of the cabin nearly impossible to access in a tight car park.

Even in my unit parking spot, I could barely access the rear seats, making it especially annoying when I just wanted to chuck a bag in the rear footwell.

Even if you don’t have trouble getting an adult back there, space is limited. Behind my own driving position, my knees were up against the seat in front, and while I had plenty of headroom, it feels a bit claustrophobic, thanks to the tiny windows and high beltline.

I’ll hand some credit to the commitment to this car’s design, though, the odd carpet trims continue into the rear doors, and there's even a plush padded surface for your elbows on either side. Nice touch. The seats also feel unusually low and sporty for an SUV, particularly an electric one.

As if it couldn’t be more clear that this car has the intention of being some sort of sports coupe, the front seats are lovely. Comfortable, supportive, and with plenty of soft trims throughout the cabin, I felt as though I had plenty of room here. The raised console design means the multimedia functions and toggles were easy to reach and use, and while the climate functions are somewhat awkwardly placed on a touch panel, at least they were set and forget most of the time.

There’s a tactile dial for volume control, and although the multimedia interface is dial-based rather than touch, Mazda’s system is one of the easiest to use once you get used to it.

There’s a large storage area under the centre console, hosting two USB ports and a household power outlet, and atop that there’s a cork-finished tray, which flips up to reveal dual bottle holders in the centre. Behind this there’s a small armrest console box, trimmed in the same plush padding as the doors and seats. Front occupants can also make use of small pockets in the doors and a glovebox.

Unlike some electric cars, the MX-30 doesn’t score a ‘frunk’, which seems like a wasted opportunity because the engine bay is half empty. Serviceable items look incredibly easy to access because of this, with liquid tanks and coolant hoses on display, but I can’t help but feeling Mazda could have put a small storage space here with some packaging trickery. It’s equally possible that there’s a crash-safety consideration, however.

Moving to the boot, and unfortunately there’s a small-hatch-sized 311 litres on offer, because there’s also next to no underfloor space, and you’ll have to store your charging cables in there, too, further reducing the space. With the cable bags strapped in place, the boot fit our largest (124L) CarsGuide travel case with little extra room to spare. It’s weekender luggage space at best, but then I suppose you won’t be able to go away for long with the range on offer anyway…

The price and features equation for electric cars is somewhat different from the status quo of their combustion equivalents. You can’t just consider standard spec inclusions, there’s a need to factor in range and charging capability, too, as battery capacity and AC to DC charging converters can have a dramatic effect on the cost.

Frustratingly for Mazda’s EV offering, the sums don’t add up as neatly as I’d like them to. The MX-30 EV is available in one top-spec trim, the E35 Astina, which wears a before-on-roads cost (MSRP) of $65,490.

This places it in the same league as the Hyundai Kona electric Highlander ($66,000), Kia Niro EV S ($67,490), and Tesla Model 3 Standard Range + which just had a significant price cut ($59,900).

To make things worse for our fledging Mazda EV, it has a WLTP-rated range of just 200km (or 225km using the ADR method)! There’s no two ways about it; this is pitiful in the face of the aforementioned rivals, all of which offer ranges in excess of 420km when measured against the same standard. Even the much cheaper base-model Nissan Leaf ($49,990) offers 270km of range.

You can’t not factor this in with an EV purchase, particularly in Australia where grand distances between cities essentially rules out any intercity trips for the MX-30 EV.

The brand is hoping this car’s funky and innovative design cues, which we’ll talk about in the next part of this review, will win the hearts of city-slickers, but the MX-30 is not lacking on the standard equipment front, either.

Stuff you’ll get out of the box includes 18-inch alloy wheels, an 8.8-inch multimedia screen (which, like this car’s CX-30 and Mazda3 siblings is a non-touch unit, controlled through a central dial), Apple CarPlay and Android Auto connectivity, a 7.0-inch semi-digital dash cluster, Bose 12-speaker premium audio, built-in sat-nav, head-up display, semi leather synthetic interior trim, full LED exterior lighting, a holographic head-up display, single-zone climate control with its own 7.0-inch touch panel controller, heated front seats, as well as keyless entry with push-start ignition.

The MX-30 has some unique interior materials, and I’m not sure why more EVs don’t have a full-size domestic power socket, as this car does under the centre console at the front. Handy for when you need to charge household devices larger than a phone on-the-go (hair-curling tongs perhaps?). There are a few spec omissions, however. Dual-zone climate, power seat adjust, and a wireless phone charger are chief among the missing.

Unlike the Mercedes-AMG C63, BMW has kept the M5’s eight-cylinder heart and this has proven to be a good decision. 

The 4.4-litre twin-turbo petrol engine has been optimised with “a cross-bank exhaust manifold and optimised oil separation”, says BMW.

The V8 spins to 7200rpm though it isn't a screamer, outputting a full-bodied 430kW (5600-6500rpm) and 750Nm (1800-5400rpm).

Augmented with a transmission-mounted 145kW electric motor that can produce up to 450Nm, thanks to pre-gearing, maximum combined outputs are 535kW and 1000Nm. 

Weight blunts punch, though, so despite nearly 100kW and 250Nm more, the new M5 is a tenth slower to 100km/h than its predecessor (claimed), at 3.5 seconds for the sprint.

You can thank a 220kW/tonne power-to-weight ratio, worse than the old car's 233kW/tonne figure. The new G90 claws some time back with brute force, hitting 200km/h in just 10.9 seconds and goes on to a limited top speed of 305km/h.

You can choose from five powertrain settings, starting with 'Electric' and 'Hybrid' for everyday use, while 'eControl' lets you store battery power for urban use.

'Dynamic' provides the best balance, says BMW, while 'Dynamic Plus' is like a qualifying mode. Think maximum combined punch for up to 10 minutes, at which point you’ll have drained the battery. 

Driving in pure electric mode, the take-off can be a little jerky but the quietude and decent power make it pleasant. Power sources are combined expertly in Hybrid and giving it some stick in Dynamic is more than enough to make your passengers feel queasy.

The MX-30 has an electric motor on the front axle with a single-speed reduction-gear transmission. It produces low-sounding figures of 107kW and 271Nm of torque, which is less than most of its rivals, although it has more power and less torque than the equivalently sized (but much cheaper) MG ZS EV.

Although these power figures don’t look as impressive as rivals, it’s worth remembering that the MX-30 has much less weight to carry around, so when it comes to driving it’s a much better story than it appears. More on that later.

The MX-30 offers three levels of regenerative braking, controlled through the wheel-mounted paddle-shifters, a necessary touch, and one that offers decent feedback on how your driving style is affecting range, via the dash and multimedia screen.

Electric-only range is rated up to 69km in WLTP testing, but the 18.6kWh battery is more likely to give you around 60km in real-world driving. It can be topped up in about two hours using an 11kW AC charger, or overnight on a three-pin socket. 

BMW includes both Mode 3 (public) and Mode 2 (home) charging cables with the M5. 

The M5 uses 3.2L/100km of 98 RON premium unleaded in ADR testing, corresponding to just 72g/km of CO2, so it should sail through the first rounds of Australian emissions regulations. 

Indulging in what the V8 has to offer sees that consumption spike, though. An enthusiastic road drive saw the M5 gulp 12.4L/100km, according to the trip computer.

The MX-30 has some advantages here, in that its tiny (35.5kWh to be precise) lithium-ion battery pack means it charges up pretty quickly. The downside? It’s not as quick as it could be, and its efficiency leaves a little to be desired.

As already discussed at length, this small battery means a very short range – between 200 and 224km depending on which standard you want to go by, and the MX-30 is claimed to consume 18.5kWh of energy on the combined cycle.

This is disappointing because not only is the claim higher than rivals like the Kona electric and Nissan Leaf, but in reality, I couldn’t best it with predominantly city driving, as I have previously been able to in all its rivals. Over some 250km of testing I managed a dash-reported 18.9kWh/100km.

The MX-30 EV takes a European-standard Type 2 CCS charger, the most popular kind in Australia, and will charge up at a rate of 50kW on DC or 6.6kW on AC.

It would have been nice to see that boosted to at least 7.2kW AC to be a bit more competitive on AC charging speed. For a car that will need to be charged frequently, even a 10-minute difference in charging time is important. While 50kW DC is about right for a battery pack this size, I assume there will be cooling issues pushing that to 100kW+ as the Hyundai Kona electric and Tesla Model 3 with nearly twice the battery size are capable of.

Mazda estimates a charge time of 36 minutes on DC, three hours on a three-phase AC charger, or nine hours from a ~2.4kW wall outlet. I charged my MX-30 a single time before returning it, from about 10 – 80 per cent, with it maxing out at around 50kW. It charged in less than 40 minutes, however, as promised.

The three M5 elements start with daily usability. We trundled out of Bathurst in electric mode, with the adaptive dampers (and other myriad settings) in Comfort. 

The M5 has steel springs, double wishbone front suspension and a five-link rear axle, all of which has been heavily reworked by the boffins at M. Naturally, the ride is firm, though in Comfort the body moves through its motions smoothly. 

The M5 is an effortless tourer, its eight-speed automatic shmoozing through ratios as it climbs and descends steep gradients. Wind and tyre noise insulation is good on coarse chip tarmac, though a bit more burble from the V8 would be appreciated. 

The M5 has nine adjustable parameters to wake it up: 'Drivetrain', 'Energy Recovery', 'Drivelogic' (gear shift aggression), 'Chassis', 'Steering', 'Brake', 'M xDrive', stability control settings and 'M Sound'. Favourite settings can be stored to the wheel-mounted M1 and M2 buttons. 

With the dampers still in Comfort the M5 remains fantastically capable with power delivery from the xDrive mighty rewarding on corner exit. Sport dampers sharpen the experience up further, amplifying the M5’s surprising agility. Thank the rear-wheel steer for this big sedan’s switchback performance. 

Step beyond the limit of grip, brake too late, or get on the power too early, though, and the M5’s mass reveals itself rapidly. It doesn’t help that the accurate steering is devoid of feel. The brake-by-wire pedal is too numb and light, as well, making it tricky to judge grip levels on the road.

Feel is less of an issue on a dry Mount Panorama circuit, where the M5 turns out to be a total pussycat. The all-wheel drive, consistent dynamics, strong brakes and well-tuned stability control make for an approachable but seriously fast sedan.

The responsive transmission will hold gears to redline and is eager on the downshift in its most aggressive setting while tactile shift paddles make commanding ratio changes yourself that bit more engaging. 

Prodigious punch out of corners is matched by the impressive consistency of the carbon ceramic brakes. The M5 pulled up for The Chase every time with minimal fuss, even from above 250km/h.

Similar credit goes to the 285mm front and 295mm rear Hankook S1 Evo tyres which remained consistent and predictable all day despite reaching temperatures over 130 degrees, according to the tyre pressure monitor.

Usually, it’s easier here to talk about how electric cars are different from their combustion counterparts, or how they are great for an electric car. In the case of the MX-30, however, it’s just a great car to drive.

I’ll admit, I didn’t expect this little EV to match, much less exceed the driving experience of its CX-30 sibling, but it was a pleasant surprise to find out how great it was.

It turns out that having a much smaller battery, and therefore a much lower kerb weight than most EVs, means the MX-30 feels light, agile, and rapid compared to all of its rivals, which goes some way to making up for its lesser outputs.

In fact, I had no trouble with the motor at all, with the MX-30 feeling faster and more responsive than the Hyundai Kona electric or the Kia Niro EV.

Mazda’s handling prowess is also on full show here, with the smooth and accurate steering allowing me to point this little SUV with remarkable accuracy. The steering tune is lighter than the Kona electric, but a bit more significant than the Kia Niro's. It emboldens you to have a bit of fun, and again, unlike rivals, Mazda’s suspension tune has your back.

It’s sporty enough to engage you, but not so firm that it sends tremors through the cabin, an impressive feat considering it has a less complex torsion bar rear. If anyone had asked me, I would have sworn it was multi-link all-round.

The whole experience feels very similar to helming the CX-30 or Mazda3, but I’d even say the MX-30 feels better over the front end, with less rough rebound than its siblings.

It also makes a cool noise. Mazda have given the MX-30 an artificial tone, plumbed through the speakers, and unlike the science-fiction hum generated by the Hyundai group EVs, the Mazda’s is a warm drone, more reminiscent of a combustion engine.

To be clear here, the MX-30 is no Tesla Model 3. That car is seriously rapid, with mind-bending handling, although I will say there’s a certain poise and refinement to the way the Mazda drives. Even in the corners, it’s confidence inspiring, with the torque-vectoring magic built into the electric motor on full show.

Perhaps one of the reasons that this car is a tad less efficient than its rivals is its lack of weight, which would allow more energy to be fed back into the battery during regenerative braking. Or perhaps its regen braking modes are a bit too forgiving, either way it’s nice that the Mazda offers three easily controllable levels via the paddle-shifters. I even became a fan of the quaint analogue power dial, even if it does give you a bit less feedback than the sleek software suites in Hyundai Group or Tesla offerings.

The MX-30, then, hits an unexpected niche. The benefits of its smaller battery pack and a focus on handling make this car one of the best EVs to drive today, even if you’re restricted to city limits, and regular recharging.

Like all recently launched Mazdas, the MX-30 is packed full of advanced ‘i-Activesense’ safety gear. In terms of cutting-edge items, this includes freeway-speed auto emergency braking, now with low-speed intersection assist as well as pedestrian and cyclist detection, lane-keep assist with lane-departure warning, blind-spot monitoring with active intervention, as well as front and rear cross traffic alert, with rear emergency braking.

The MX-30 also has the expected suite of electronic assistance but goes further to include torque vectoring and has a total of 10 airbags – a lot for a very small cabin. It also comes packed standard with front and rear parking sensors, as well as a 360-degree parking camera suite. It’s amongst the best safety suites in terms of pure features in the small SUV segment.

The MX-30 has a maximum five-star ANCAP safety rating to the 2020 standards.

In Australia, BMW has moved to match other manufacturers in offering a five-year/unlimited kilometre warranty on all its cars. 

Servicing is recommended on a condition basis, with the M5’s multimedia system prompting a visit to the mechanics. BMW offers pre-paid service packs for five years/80,000km at a price of $5059 for the basic offer and $8152 for 'Inclusive Plus', which covers brake pad and rotor replacements. 

It is expensive next to a regular 5 Series but when you consider the purchase price and performance level, the M5’s service pricing is not astronomical. 

The MX-30 is covered by Mazda’s industry-standard five-year and unlimited kilometre warranty, while the battery pack is covered by a separate eight-year promise, on par with its Korean rivals. Mazda includes roadside assist for the duration of the warranty.

The EV has service intervals of 12 months or 15,000km whichever occurs first, and a five-year service plan comes in at $1273.79, working out to an average of $254.76 a year. That’s getting close to Toyota levels of cheap servicing, and so it should, given electric cars (at least in theory) have much less to attend to when it comes service time.
