BMW M5 vs MG MG5

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 MG5 works well as a budget-friendly small car, and it’s genuinely good to drive.

Some small let-downs in terms of packaging don’t detract from this car in any major way, but the lack of active safety is a concern considering the features most of its rivals offer.

If it’s on your shopping list, make sure you know what else is on offer in terms of safety before you lock in the MG5 for the savings.

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 MG5’s styling might be a little divisive, with the overall shape and look of the small sedan sitting somewhere between its direct rivals, like the Hyundai i30 Sedan, and aspirational models like the Mercedes CLA.

In this Essence variant, the grey insert for the grille gives the front a darker, more aggressive look, though the way the grille mesh weaves makes it look a little like moustache hair.

The large ‘intake-style’ design at the sides gives it a sportier look than its outputs have perhaps earned - not to say the MG5 is sluggish - and following those around to the side of the car leads to a fairly minimalistic and tidy silhouette.

Here, probably most notable is the rather tall gap between the tyres and wheel arches.

The rear, with that sloped-up roofline, transitioning into a gentle lip spoiler, flanked by those lights, is where CLA fans might have the most to say about the MG5’s design.

Notably, the exhaust vents at the bottom are fake. The real exhaust exit is hidden well underneath.

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.

Some newer brands to Australia, often MG’s compatriots from China, get some of the ergonomic or tech basics wrong as they focus more on an impactful first impression. Fortunately, MG doesn’t do that, for the most part.

Inside the MG5 is a cabin that looks more expensive than it is, but has some useful features to back it up without the superfluous add-ons.

Aside from the lack of physical climate controls - an annoying cost-saving or interior-tidying trend embraced by brands from budget to bougie - the MG5’s interfaces and ergonomics are pretty sensible.

Accessibility ticks for the steering wheel buttons being few and large enough to use without needing to look, as well as the lack of a panel of buttons and switches in the centre console. Looking at you, BMW.

The screen is also functionally sound, with obvious menu layouts and fairly large buttons as touch points, so it doesn’t feel like trying to operate a tablet while you’re driving.

It does, again, lose points for the climate control situation, which weirdly features a temperature slider as a colour gradient rather than numerical temperatures.

No wireless phone charger means needing space for a plugged-in phone, which the MG5 has just enough of, though similarly ‘just enough’ is the size of the cupholders, which won’t fit a big water bottle.

In the rear, there’s space enough for an adult to sit comfortably behind another adult, though it’s not the place for long journeys.

Strangely, there’s only one central vent control in the rear so only one passenger gets cool air or heat, plus there isn’t a great deal of storage. No armrest or cupholders for rear passengers, either.

Also noteworthy is the single-piece rear seat, which means if longer items need to be transported in the 401-litre boot, the whole rear seat must be folded down and the MG5 temporarily becomes a two-seater.

Under the boot floor is a space-saver spare, though, so bonus points for a more useful addition than a simple repair kit.

MG has managed to cram quite a bit into the MG5 for less than $25K drive-away in its Vibe entry-level variant.

More specifically, you’re forking out $24,990 to head off from the dealership in one, even with its missing active safety features, but we’ll come back to that.

In Vibe specification, the MG5 comes with 16-inch alloy wheels, auto LED headlights, a reversing camera and a tyre pressure monitor, while inside you’ll find a 10.0-inch touchscreen with Apple CarPlay and Android Auto capability (both wired) with four speakers for the sound system, as well as a push-button start, synthetic leather seats and three different selectable steering modes.

Stepping up to the Essence, which we’re testing here, costs $28,990 drive-away and adds a sunroof, a six-speaker sound system, electric seat adjustment for the driver, steering wheel paddle shifters - for a reason we’ll return to - and turns the rear-view camera into a surround-view parking camera.

The Essence is also visibly different on the outside thanks to slightly larger 17-inch alloys, auto-fold (when locked) side mirrors, and a grey grille insert rather than body-coloured.

On that, you can have white or yellow as no-cost paint colours in either MG5 variant, but metallic red, blue, black or grey are all $700 options.

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.

Both versions of the MG5 come with a 1.5-litre four-cylinder engine that drives the front wheels, but the similarities mostly end there.

In the entry-level Vibe, that engine is naturally aspirated and makes 84kW and 150Nm - similar to the MG3. Power is transferred to the front wheels via a continuously variable transmission (CVT).

In our Essence variant the engine is turbocharged and makes a suitably higher 119kW and 250Nm, driving the front wheels via a seven-speed dual-clutch automatic transmission.

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 naturally aspirated Vibe's official combined cycle fuel economy figure is 5.7 litres per 100km, while the turbocharged Essence drinks a little more at 5.9L/100km.

For comparison, Toyota claims its non-hybrid Corolla Sedan will sip 6.0L/100km, while a Mazda3 Sedan claims 6.1L/100km. Not bad, then, if you can keep it near MG’s claim.

During our testing, with a mix of city, suburban, highway, and rural driving, the MG5 Essence burned through 95 RON premium fuel at a rate of 9.1L/100km, checked at the pump, though I wouldn't expect this to be representative of normal, calmer day-to-day driving.

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.

Perhaps the biggest surprise about the MG5 is that it’s quite good to drive. And not just ‘for an MG’ or ‘for a car from China’. It’s actually good.

The turbocharged engine takes a moment to get going, and the dual-clutch can be a little hesitant off the mark.

The combo of the two means sometimes you need to plan your take off ahead of time - but in its above-3000rpm sweet spot, the Essence has a good bit of urgency to it.

That’s fortunately paired with a combination of comfortable suspension and a composed chassis, with well-weighted steering.

On urban roads and with a little awareness of the slow take-off, the MG5 is capable and well-suited to small roads, though it can be a little frustrating in stop-start traffic.

On the other hand, outside the confines of city driving, the small sedan is more dynamic than you might expect, able to get up to speed and comfortably overtake on highways, as well as handle corners on twisty roads confidently.

Potholes and rough sections of road don’t rattle the MG5 as much as you might expect from a car in this segment, though road noise can be a intrusive on coarse roads - of which Australia has many.

Dare I say it - the MG5 is rather fun.

Here’s the bit that might turn potential owners off the MG5. Or here aren’t the bits, more accurately.

The MG5 comes with a short list of safety features that amount to the minimum standard for a car to be sold in Australia.

That is, six airbags, autonomous emergency braking (AEB), anti-lock brakes (ABS) and electronic stability control (ESC).

MG also lists hill-hold under its safety features, as well as its active cornering brake control and auto door unlock and activation of hazard lights in case of an accident.

There are also ISOFIX and seat tether points for the outer rear seats.

The reverse camera in the Vibe is replaced by a surround-view camera in the Essence, though the visual quality of the feed leaves a bit to be desired.

Crucially, it’s missing a host of safety features that would be standard, or at least optional on a rival like the Toyota Corolla Sedan or Mazda3 Sedan, like steering assist, a pre-collision safety system, pedestrian detection, active cruise control and even lane departure alert.

Rear cross-traffic alert and blind-spot monitoring? Nope.

MG Australia CEO Peter Ciao told CarsGuide not long ago it’s about keeping the price of the car accessible for more customers, which means you’ll have to make your own call regarding whether it’s safe enough for you.

To that, ANCAP hasn’t crash tested the MG5, but if it did we wouldn’t expect it to score any higher than three stars.

While we don’t know how it would hold up in the area of crash protection, it lacks too much of the active safety gear that ANCAP expects of a maximum five- or even four-star car.

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. 

MG offers a seven-year/unlimited kilometre warranty on the MG5 as with all its models - even electric cars. That also comes with roadside assist for the duration of the warranty, though only 160,000km is covered by the warranty if the car is used for commercial purposes.

Servicing prices for the MG5 range from $266 or $272 for the Vibe or Essence, respectively, up to $581 or $661 for the most expensive of the seven 10,000km/12-month scheduled services.

The total cost of servicing the Vibe over its seven years under capped-price servicing comes to $2661, or about $380 average per service. For the Essence, that bumps up to $2764 or an average of about $394 per service.
