BMW M8 vs Mazda 3

What's the difference?

With dramatic looks, a luxurious spec, and impeccable quality, the BMW M8 Competition Gran Coupe remains supremely well controlled as it delivers eye-widening performance and amazing dynamics. But there’s an ‘edge’ to the experience you need to be ready for. If I was determined to head for the Aussie ‘fast lane’ in a BMW 8 Series Gran Coupe I’d opt for the M850i and pocket a lazy $71K (enough for a cheeky M235i Gran Coupe to add to your collection).

Given how effortlessly it traverses the mainstream and premium small car classes, the Mazda 3 might be the best value small car on the planet.

With racy styling, sports car handling, classy interior presentation and impressive, intelligent efficiency, there’s plenty to sink your teeth into here.

Poor rear vision, a dark back-seat area and smallish boot aside, it doesn’t have any glaring faults.

In a world overrun with SUVs, props to Mazda for evolving the small car so brilliantly to mask a half-decade of existence. Continuous improvements have made the 2024 G25 Evolve SP Vision an essential small car shortlist proposition, regardless of price.

Want to start a vigorous car enthusiast discussion (more a verbal punch-up)? Simply ask whether a four-door car can be a coupe.

Traditionally, the answer is no, but over time numerous automotive brands have applied that description to cars with more than two doors, including SUVs!

So, here we are. A four-door ‘Gran Coupe’, and the M8 Competition version retains the smoothly tapering turret and frameless side glass that help give selected BMW four-door models the same swoopy, coupe look.

At close to 4.9m long, a fraction over 1.9m wide, and under 1.4m high, the BMW 8 Series Gran Coupe has a firmly planted, low-slung, wide-track stance. Always a subjective call, but I for one, think it looks stunning, especially in our test car’s ‘Frozen Brilliant White’ matt paint finish.

In an era of comically oversized BMW grilles, things are relatively under control here, with a bright black finish applied to that ‘kidney grille’, as well as the huge front bumper air intakes, front splitter, front fender vents, exterior mirrors, window surrounds, 20-inch rims, lip spoiler on the boot, rear valance panel (incorporating a functional diffuser), and quad exhaust tips. The roof’s black, too, but that’s because it’s made of carbon-fibre.

Overall the M8 Competition Gran Coupe is a compelling combination of strong, confident character lines along the bonnet and lower flanks, with tightly wrapped curves following the high hip line, and more organically irregular, yet distinctly BMW shapes in the head- and tail-lights. 

The interior is a beautifully balanced design with a broad centre console sweeping up to the middle of the dash and wrapping around to focus on the driver, in typical BMW fashion.

 The multi-adjustable sports front seats are immaculate, with high-end quilting in the centre section matching a similar treatment in the doors. The dark grey (full) leather trim is offset by carbon and brushed metal trim elements for a cool, calm and focused feel.

Crack the bonnet open and a spectacular ‘BMW M Power’ carbon cover dressing the top of the engine is guaranteed to impress friends and family.

How is it that the current Mazda 3 is already five years old? This hatchback is still stunning, the sort of car you look back at when walking away.

The shape is sleek and almost coupe-like, with a shark-like nose, cab-backward-style long bonnet, upswept shoulder line and a fastback silhouette.

More importantly, it’s the way the light dances across the sculptured sides that draw the eyes in. Bereft of clutter, it makes you wish all mainstream manufacturers had the courage to be so daring.

We’ve said it before – the 'BP'-generation Mazda 3 (Axela in Japan) is the brand’s boldest C-segment hatch since the 1993 'BA' 323 (Astina/Lantis/323F).

But there’s a price to pay for such timeless beauty…

Of the M8 Competition Gran Coupe’s 4867mm overall length, 2827 of it sits between the front and rear axles, which is a pretty healthy wheelbase for a car this size (and 200mm more than the 8 Series two-door coupe).

Space up front is generous, and one upside of a four-door, rather than two-door coupe, is you’re not struggling quite so much for space to get in and out when parked next to other cars.

Once inside, there’s plenty of storage up front, with a large lidded box/armrest between the front seats, twin cupholders in the centre console, as well as another covered area for wireless phone charging and extra bits and pieces in front of that. Long door pockets provide space for bottles, and the glove box is a decent size. There’s 12V power as well as USB sockets for media connection, with charging outlets in support.

At first glance you’d swear the rear seat was designed as a two-seater only, but when push (literally) comes to shove a centre passenger can squeeze in, legs straddling the rear console.

In terms of legroom, at 183cm (6’0”) I could sit behind the driver’s seat set for my position with knee room to spare, but headroom is another matter, with my noggin making solid contact with the soft Alcantara headlining. It’s the price you pay for this car’s racy profile.

There’s a neatly trimmed storage box and two cupholders in the fold-down centre armrest, plus door pockets with enough room for small bottles. The rear console houses dual climate controls, twin USB power sockets, and a small oddments tray, as well as buttons for the optional rear seat heating fitted to our test car ($900).

The 440-litre boot is a bit like the car itself - long and wide, but not very high. The rear seat split-folds 40/20/40 if you need more space, and the boot lid is automatic with a hands free function. But don’t bother looking for a spare of any description, a tyre repair kit is your only option.

There is a price to pay for all this quasi-coupe styling flair, and that’s a comparatively snug-feeling interior, though you’d never call it cramped.

Actually, the Mazda 3 is no less spacious than most of its competition in all but one area, with enough room even for 200cm drivers, along with sufficient shoulder width and ceiling height to match.

If you’re really tall, maybe that missing sunroof isn’t such a bad thing, after all.

Sat so low-down on cushy, enveloping front seats that offer plenty of comfort and support, this is the anti-SUV. Maybe Mazda should have called this the MX-3.

Sporty and spot-on, the driving position is a laid-back affair, with an emphasis on better ergonomics, as emphasised by the thoughtful placement of switchgear that’s all within easy reach, ahead of a beautifully flowing and layered dash. Proudly Japanese in flavour, it brings to mind functional minimalism.

Drilling into some of the 3’s finer interior details, the analogue-look digital instrumentation is super-legible, ultra-classy and gorgeously lit at night. As previously mentioned, the dials and surrounding air vents are reminiscent of the later Porsche 944 and 968.

It’s not just all for the sake of aesthetics, either.

Yes, it’s lovely, but the thinned-rim three-spoke steering wheel feels great to grip, with nifty little paddle shifters that are a delight to prod.

Same goes for the physical volume knob and climate-control buttons, sidestepping the need to get distracted and frustrated by virtual sub-menus.

And having a conventional gear lever with old-school Tiptronic-style shifts suits the 3’s athletic vibe.

Plus, forward vision is A-OK, ventilation is faultless, storage is better than you might expect, and the fit and finish is as good if not better than any of this 3’s German premium opponents.

Out back, the split-fold rear backrest is set at a comfortable angle, the cushion is well padded, and you’re provided with USB ports, air vents, and an armrest with two cupholders. More thoughtfulness.

But while knee room is fair, rear headroom isn’t great if you’re tall or wear a beehive, as the falling ceiling line reveals.

Vision out is limited by that rising window line and fat pillars. Getting in and out of the back requires some contortionist moves. And the small windows mean it can be gloomier in the back than a Smiths album.

Finally, at just 295 litres, the 3’s cargo capacity is disappointing. Sure, it eclipses the Corolla hatch’s 217L cubby, but other rivals are far larger back there.

At least the floor is wide and flat and there are 60/40-split backrests for cabin access for longer items.

Note that a space-saver spare wheel lurks underneath. Mazda argues there’s always the closely-related CX-30 if you need (slightly) more space (317L).

Meanwhile, at the other end of the 3…

Mazda has rationalised the MY24 3 range, with fewer grades and no more manuals, sadly.

The pretty little piece of automotive industrial design you see here is the mid-range Evolve SP Vision, which sounds less like a car and more like a posh hairdryer from Vidal Sassoon.

Priced from $36,520 before on-road costs (or about $41K drive-away before you start haggling), this Mazda 3 is a sporty and well-equipped alternative to the likes of the speedy Hyundai i30 N-Line Premium, spacious Kia Cerato GT Turbo, new Subaru Impreza AWD 2.0R and evergreen Toyota Corolla ZR. All cost roughly the same money.

The thing is, do Mazda’s upmarket aspirations mean the 3 possesses the ride quality and chic to embarrass at times substantially more expensive hatchbacks with premium pretensions? We’re talking rivals like the BMW 1 Series, Mercedes-Benz A-Class, Peugeot 308 and VW Golf, here.

Stay with us, because we reckon you might be surprised by how far the 3 has come since its humble 323 predecessors.

Anyway, this version comes with most of the good gear, including a full suite of driver-assist safety tech like front and rear Autonomous Emergency Braking (AEB), blind-spot alert, lane-keep assist and adaptive cruise control, as well as keyless start and walk-away lock, powered driver’s seat with memory, 360-degree camera views, a head-up display, digital radio, sat-nav, auto tilt/folding exterior mirrors, dual-zone climate control, Bluetooth phone/audio connectivity and 18-inch alloys.

Oh, and for 2023, an upgraded version introduces a smartphone charger and wireless for the Apple CarPlay/Android Auto function, along with USB-C port access front and rear.

What’s missing at the Evolve SP Vision’s price point? Some mainstream rivals offer leather and a sunroof, available respectively in the more-expensive GT Vision, from $40,000, and flagship Astina grades, from nearly $42,500.

Still, that’s quite a lot of small car for the money, given the quality of the presentation and design. Speaking of which…

The M8 Competition is powered by an all-alloy, 4.4-litre twin-turbo V8 engine, featuring direct-injection, as well as the latest version of BMW’s ‘Valvetronic’ variable valve timing and ‘Double-VANOS’ variable camshaft control, to produce 460kW (625hp) at 6000rpm, and 750Nm from 1800-5800rpm.

Designated ‘S63’, the engine’s two twin-scroll turbos are located, along with a cross-bank exhaust manifold, in the engine’s (90-degree) ‘hot vee.’ 

The idea is consistent transmission of exhaust energy to the turbos for improved response, with the reversal of usual practice completed by inlet manifolds positioned on the engine’s outer edges.

Drive goes to all four wheels via an eight-speed ‘M Steptronic’ (torque converter) auto transmission with ‘Drivelogic’, and dedicated oil cooling, as well as BMW’s ‘xDrive’ all-wheel drive system.

The xDrive set-up is built around a central transfer case housing an electronically-controlled, variable multi-plate clutch, with front to rear drive distribution set to a default 40:60 split.

The system monitors multiple inputs including, wheel speed (and slip), acceleration and steering angle, and is able to vary the ratio up to 100 per cent rear thanks to the ‘Active M Differential.’ 

When you think about it, shoehorning a big torquey engine in a light and agile small car is a recipe for fun. Ford did just that with the Escort RS2000 in the 1970s… and Mazda’s now an expert at it, too.

The engine in question is the G25, a 2.5-litre four-cylinder naturally aspirated twin-cam petrol engine, delivering 139kW of power at 6000rpm and 252Nm of torque at 4000rpm.

As this Evolve SP Vision hatch tips the scales at 1415kg, it makes for a healthy, and consequently very lively, power-to-weight ratio of over 98kW/tonne.

That’s if you decide to use all the available revs, which the six-speed torque-converter auto makes great use of.

Driving the front wheels, it offers a 'Sport' mode to extend the revs even more, which is keeping in line with this Mazda’s sporty character.

Less so is the company’s decision to ditch the old multi-link independent rear suspension system a few years back for a more prosaic torsion beam arrangement. We’ll get to how that affects ride and handling in a moment.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 10.4L/100km, the M8 Competition emitting 239g/km of CO2 in the process.

Despite the standard auto stop/start function, over a week-long combination of city, suburban, and freeway running we recorded a (dash-indicated) average of 15.6L/100km.

Pretty thirsty, but not outrageous when you consider this car’s performance potential, and the fact that (purely for research purposes) we exploited it regularly.

Recommended fuel is 98 RON premium unleaded, and you’ll need 68 litres of it to fill the tank. That equates to a range of 654km in line with the factory claim, and 436km using our real-world number as a guide.

Mazda claims the G25 averages 6.6L/100km on the combined cycle… for a carbon-dioxide emissions rating of 154g/km. On a 51L tank, that gives a potential distance of over 940km!

Driven good and hard in our hands, we managed 7.5L/100km, which isn’t bad given the speed and conditions it was subjected to.

Plus, the Mazda’s happy on 91 RON 'standard' unleaded petrol.

There’s something teutonically symmetrical about the way the M8 Competition Gran Coupe delivers its prodigious thrust.

Peak torque of no less than 750Nm is available from just 1800rpm, remaining on full song across a broad plateau all the way to 5800rpm. Just 200revs later (6000rpm) peak power of 460kW (625hp!) takes over to finish the job, with the rev ceiling sitting just over 7000rpm.

That’s enough to slingshot this 1885kg bruiser from 0-100km/h in 3.2 seconds, which is supercar fast. And the engine and exhaust noise produced by the 4.4-litre twin-turbo V8 during such rapid acceleration is suitably brutal, courtesy of electronically-controlled flaps in the system opening up. 

On a more civilised drive you can reduce the exhaust noise via an ‘M Sound Control’ button on the centre console.

The eight-speed auto is fast and positive, especially in manual mode, which dials up the fun via wheel-mounted paddles. And when it’s time to direct this car’s forward momentum into lateral movement BMW has brought in the engineering heavy artillery.

Despite its frameless door body structure the M8 Competition Gran Coupe feels solid as a rock thanks in no small part to its ‘Carbon Core’ construction, using four primary components - carbon-fibre-reinforced plastic (CFRP), aluminum, high-strength steel, and magnesium.

Then the ‘Adaptive M Suspension Professional’ (with active anti-roll stabilisation), the tricky xDrive continuously variable AWD system, and active M Sport diff combine to keep everything under control.

Suspension is a double wishbone front, five-link rear arrangement, with all key components in alloy to minimise unsprung weight. In concert with the electronic wizardry on-board, it helps keep the M8 buttoned down with only modest body roll in enthusiastic cornering, as the rear-biased AWD system seamlessly distributes drive to the axle and wheels that can make best use of it.

The price you’ll pay for the track-ready tune is in compromised ride comfort. Even in the ‘Comfort’ setting, the M8 Competition is firm, and feels corrugations and imperfections to a surprising degree.

An alignment of the BMW 8 Series planets left me with the keys to this car and the M850i Gran Coupe (also using the Carbon Core body) at the same time, and the difference between their softest settings is appreciable.

Also be aware that at 12.2m the M8 Gran Coupe’s turning circle is substantial, and it’s just as well all that camera, sensor and self-parking tech is available to help you guide this ship into port.

The M8’s electrically-assisted, variable-ratio steering features an ‘M’ specific calibration to deliver satisfying precision and good road feel. But in similar fashion to the ride a noticeable amount of unwelcome feedback comes through to the wheel.

The fat Pirelli P Zero rubber (275/35 fr / 285/35 rr) grips hard, and the monster brakes (ventilated all around, with 395mm rotors and six-piston calipers up front) wash off speed without fuss or fade.

But overall, you’ll have to live with a less refined drive when you sign on for the M8 Competition. Straight away it feels faster but lacks the M850i’s lighter touch. No matter which drive or suspension mode you select, responses are more aggressive and physical.

To fully explore and enjoy the M8 Competition’s abilities it feels like the race circuit is its most appropriate habitat. On the open road, the M850i is all the Gran Coupe you’re going to need.

Ask yourself. What do you want from a new small car?

Since the first Familia of the early 1960s, Mazda’s been at it constantly, through the 1300 and 323 eras and into the modern age of the 3.

The Hiroshima brand knows its stuff. Space, practicality, comfort, ease, reliability and affordability. But a small car has to offer more, specifically in the way it makes the owner feel.

That’s why, while the Focuses, Lancers, Astras and Pulsars are gone, the 3’s still here. And it isn’t just the lush visuals inside and out that are, well, sensory-rich.

As older Alfa Romeo owners know, there’s something special about an engine that sounds alive, and the moment you push the 3’s starter, it purrs into life. That’s the first clue.

Slot the refreshingly old-school lever into Drive, and the G25 leaps into action, and, if you need it to, will keep pulling forward strongly, engine buzzing, like it’s on a mission.

That describes the torquey urge of this big 2.5L four, paired perfectly with the sensibly-geared auto.

We miss Mazda’s magnificent manual immensely, but the 3’s instant response reflects its favourable circa-100kW/tonne power-to-weight ratio.

And, as we’ve harped on in the past, the twin-cam unit’s extra oomph beyond 4000rpm delivers muscular high-speed responses akin to a good turbo – or a great old-school Alfa. You can keep your laggy dual-clutch transmissions, Europe.

Now, sweet, smooth and speedy performance is one thing, but having the chassis tuned with precise and fluid steering for tactile handling, and confident roadholding, backed by nuanced driver-assist and traction controls, are another.

There is a consistent and unifying control to the 3’s linear and forgiving dynamics, reminiscent of past masters like the Focus (and today’s brilliant Peugeot 308) that makes it a joy to drive enthusiastically through fast corners, with the knowledge that it won’t suddenly snap-oversteer and bite an unalert driver back.

For a Mazda, the ride is quiet enough, but there is still some droning transmitted through the cabin, via the Bridgestone Turanza (215/45) tyres, on coarse-chip bitumen surfaces.

And while suspension comfort is pretty impressive for the most part, larger bumps reveal the torsion beam’s limitations, as the car can occasionally thud over them in a way that we remember the multi-link rear end wouldn’t.

Anyway, what we’re saying is that, overall, the 3 Evolve SP Vision is an immersive and interactive driving experience that is right up there with the best of them.

Brawny performance, exquisite agility and a refinement that, collectively, have eluded every small Mazda in living memory until this generation’s 2019 debut. This 3’s right on the money. Still.

Tested way back when this generation was new in early 2019, the Mazda 3 scored a maximum five-star ANCAP crash-test rating.

On the driver-assist front you’ll find front and rear AEB (with a working range of 40km/h to 200km/h) with pedestrian and cycle detection available between 10-80km/h, while the 'Forward Collision Warning' operates from 40-200km/h.

Blind-spot monitoring, lane departure warning, lane-keep assist, 'Forward Obstruction Warning', rear and front 'Cross-Traffic Alert', 'Secondary Collision', auto high beams, breakaway pedals, adaptive cruise control (with full stop/go functionality and cruising/traffic support), parking sensors front/rear, 360-degree round-view monitor, reverse camera, traffic sign recognition, driver monitor and tyre-pressure monitors are also included.

The lane-keep support systems work between 55-200km/h.

Seven airbags – front, side, curtain and a driver’s knee bag – are fitted, along with anti-lock brakes with 'Electronic Brake-force Distribution', 'Emergency Brake Assist', stability control, traction control, hill-start assist are also fitted, seat-belt pretensioners, and two rear-seat ISOFIX points as well as three top tethers for child seat straps.

BMW offers a three year/unlimited km warranty, which is at least a couple of years off the mainstream market pace, and lagging other premium players like Mercedes-Benz and Genesis, both sitting at five years/unlimited km.

Roadside assistance is included for the duration of the warranty period, and the standard ‘Concierge Service’ provides everything from flight information, to global weather updates, and restaurant recommendations, from a real human.

Technically, service is ‘condition based’ with the car telling you when it’s time to hit the workshop, but you can use every 12 months/15,000km as a guide.

BMW Australia offers ‘Service Inclusive’ packages that require customers to pre-pay for servicing, allowing the cost to be covered off in finance or leasing packages and reducing the need for concern about paying for maintenance further down the track.

BMW says there are different packages available, from three to 10 years, or between 40,000 and 200,000km.

Mazda offers a five-year/unlimited kilometre warranty, with five-years roadside assistance… and that’s nothing special nowadays.

Service intervals are at 12 months or every 15,000km.

A fixed-price service scheme is available, averaging out to $434 annually over the first five years. Mazda shows pricing right up to 16 years and 240,000km on its website.
