What's the difference?
Few cars carry the burden of expectation more than the BMW M3 – and, by association – the two-door versions latterly rebadged M4. Porsche 911 definitely. Mazda MX-5 probably. Ford Mustang maybe. Icons all.
Since the arrival of the left-hand-drive-only – thus it never officially came to Australia – E30 3 Series two-door original in 1986, it’s become the benchmark for which all others follow, and regular finalist in any given ‘greatest sports car of all time' listings.
Except… it hasn’t always turned out that way.
After the visceral E30 M3, it’s been a rollercoaster ride of disappointment and elation: by 1992’s patchy E36 arch enemies Audi and Mercedes-Benz were chiming in, only to be swept aside by the exquisite E46 M3 from 2000. But then its 2007 E90 and 2014 F80 successors both missed their marks for reasons we’ll go into later, leaving us with 2021’s G82/3 generation.
Does the latest two-door M-car return to form? We take a look at the M4 convertible, which simultaneously rediscovers the fabric roof and adopts all-wheel drive (AWD) for the first time.
Glorified blow dryer or glorious mind blower? Let’s see.
The right lane on Aussie freeways is occasionally referred to as the ‘fast lane’, which is laughable because the highest legal speed in the entire country is 130km/h (81mph). And that’s only on a few stretches in the Top End. Other than that, 110km/h (68mph) is all you’re getting.
Sure, a 'buck thirty' isn’t hanging around, but the subject of this review is a 460kW (625hp) four-door missile, capable of accelerating from 0-100 km/h in 3.2 seconds, and on to a maximum velocity somewhat in excess of our legal limit.
Fact is, the BMW M8 Competition Gran Coupe is born and bred in Germany, where the autobahn’s left lane is serious territory, with open speed sections, and the car itself the only thing holding you back. In this case, to no less than 305km/h (190mph)!
Which begs the question, isn’t steering this machine onto an Aussie highway like cracking a walnut with a twin-turbo, V8-powered sledgehammer?
Well, yes, But by that logic a whole bunch of high-end, ultra high-performance cars would instantly become surplus to requirements here. Yet they continue to sell, in healthy numbers.
So, there’s got to be more to it. Time to investigate.
We cannot think of a faster or more invigorating four-seater luxury convertible for the money than the new M4 Competition.
Finally, after years of devastatingly fast droptops with remote steering and an unforgiving ride, the G83 generation discovers refinement and sophistication to go with its supersonic speed.
There’s terrific talent on tap here that no rival can even come close to right now. BMW is on a roll and this is the first M4 convertible that can sit proudly alongside the best of its classic M3 ancestors.
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).
Hallelujah! The unloved folding hardtop is history and fabric is back in fashion in a BMW 3/4 Series-based convertible for the first time since the demise of the E46 convertible in 2006.
It improves the proportions and aesthetics out of sight while remaining superbly insulated. It’s also 40 per cent lighter to boot while liberating 80 litres of extra luggage space.
The roof requires just 18 seconds to drop away or erect again, and can be done so at speeds of up to 50km/h. And it looks great, with a taut fit that suits the BMW’s lithe lines to a tee. With all four windows dropped, it also does a fab impression of an American-style pillarless hardtop.
Roof up or down, the M4’s muscular styling has a tense sparseness to it that means business, reinforced by that oversized, M-specific kidney grille treatment that, admittedly, isn’t as divisive in real life. The smiley LED light wave out back also brings a friendlier tone, harmonising handsomely with the rest of the car.
This is probably the best-looking BMW convertible since the beautiful E46 era.
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.
The M4 Convertible is not a paragon of space efficiency, given its footprint.
At nearly 4.8 metres long and 1.9m wide, the M4 Convertible casts a sizeable shadow on the road, which only really pays dividends for front-seat occupants inside.
Ours was fitted with a very handsome pair of $7500, two-tone M Carbon bucket seats up front, a sort of futuristic tombstone design with a fixed headrest that looks like they were created by and for Stormtroopers; they do provide all the electronic adjustability one would need in terms of fore/aft, up/down and lumbar support movement.
But, unless you really need their g-force-bracing support and love their outrageous appearance, they are monumentally obstructive to effortless entry/egress and overall hip comfort if you don’t possess a gymnast’s physique. In fact, at times, they can feel downright torturous, especially in the gusset area due to the pointless (ironically) hard central bulge bit. The standard front seat set-up is perfectly fine, offering all the comfort and support expected in a luxury convertible, with the added bonus of headrest adjustability.
As with all G20/G80 generation 3/4 Series, the M4’s interior is a welcome return to form for BMW, from the excellent driving position and superb build quality, to thoughtful switchgear placement, brilliant ventilation and ample storage. And iDrive is probably the best and most intuitive multimedia system out there, too, needing no special skill or distraction once mastered.
A quick note about the instrumentation. The 4 Series design digital readouts are prettier than the standard 3 Series' ugly standard screen that looks ex-Honda Civic. This one offers alternative views and is easy to read at a glance. But it still makes us pine for good old analogue dials. Remember when BMWs were the world leaders in dial design?
Some familiarisation is also required to figure out the M part of the M4, including the various driving and performance modes; they’re divided into Road, Sport and Track settings. Yet, thankfully, they’re all far simpler to get your head round than before, which required too much fiddly concentration, since – once quickly learnt – everything is possible with eyes-on-the-road promptness. A new M Mode button offers pre-determined shortcuts to whichever drive combinations are desired.
The roof is well insulated, meaning that previous-gen folding hardtop-owning prospective buyers shouldn’t be too sad about the fabric above their heads. On the go, front occupants can enjoy a variety of configurations, starting with snug coupe-style cosiness and security, moving to cool pillarless hardtop-style windows-only down cruising, to the full top-down convertible glory. The latter also brings minimal buffeting at speed unless you’re stuck out in the back. Roof-up vision isn't brilliant, though.
Strangely, with the M Carbon bucket seat options ticked, it’s actually easier for some people to get into the back than the front. Pulling a strap sees the front bucket seats (slowly) whir as far forward as possible to allow sufficient room for people to clamber onto the rear seats.
Once sat, it’s clear that longer-legged people will struggle. Knee room is OK (especially if the front occupants are feeling sympathetic by moving their seats forward), there’s surprisingly adequate head room for your 178cm tester when slightly slouched, big feet can be tucked beneath the front seats and scalps never have to touch the rear glass thankfully.
And at least BMW has tried to make life back there comfier for smaller people, due to rear-facing air vents with climate and directional control, two USB-C ports, a pair of cupholders, a centre armrest and some handy storage. The materials are of a high quality construction, too.
However, the fixed back rest is far too upright, the knees-up posture quickly gets tiresome, the cushion is firm and you’re sat on a slight angle pointing outwards. Claustrophobics won't be too happy either. Annoyingly there aren’t side window buttons either, meaning only the driver can lower or raise them. The two-seater back seat is best saved for short trips or kids.
Happily, once the roof is dropped, the hemmed-in feel vanishes, there’s not too much wind intrusion or buffeting with the side windows up and there’s a sense of shared freedom that only a four-seater convertible can bring. Going the full drop-top experience will ruffle more than hairdos at freeway speeds, though. An optional wind deflector can fix that issue for front-seat occupants, but it goes over the back seats, turning the M4 into a two-seater ragtop.
Further back, the 300-litre boot isn’t accessible from the cabin, meaning you can’t put much inside at all. BMW fits a hinged flap that needs to be down for the roof to work since it cordons off the roof storage part of the boot when folded in; when lifted, there’s a useful amount of space for luggage, and it’s a handy rectangular shape instead of an L-shaped slot, but obviously at the cost of convertible driving. You can’t have both.
Note that, compared to the previous folding-hardtop M4, this boot is some 80L larger.
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’s only one M4 Convertible available, in Competition M xDrive guise, and it’s not lacking for much.
We’re looking at a 375kW/650Nm 3.0-litre twin-turbo in-line petrol six-powered four-seater AWD ragtop capable of 0-100km/ in 3.7 seconds, on the way to either a 250km/h or optional 280km/h top speed, if your wallet allows. All from $176,900 before on-road costs. BMW’s serious here.
Standard features include an active M differential, adaptive suspension with auto levelling, an M Compound Brake package and selectable driving modes, underlining the M4's driver focus.
You'll also find leather upholstery, head-up display, adaptive cruise control with full stop/go functionality, automatic parking assist, a surround-view camera, a lap timer and “drift analyser”, paddle shifters, wireless smartphone integration including Apple CarPlay/Android Auto connectivity, emergency services access, three-zone climate control, electric front seats with memory, front seat heaters, ‘air collar’ neck warmer, keyless entry/start with BMW Digital Key, key fob control for windows, roof and boot opening, split-fold rear backrest, M carbon fibre trim, leather steering wheel, a 12.3-inch instrument display, a 10.2-inch control display, 16-speaker Harman/Kardon surround-sound audio system, digital radio, MP3 player, cloud-based satellite navigation, trip computer, wireless charging, ‘Hey, BMW’ assistant, outside connected services assistance, ambient lighting, BMW LED Laserlight auto high beams with active cornering and light sensitivity, rain-sensing wipers, electric heated/folding exterior mirrors, tyre pressure monitors, 19-inch front/20-inch rear wheels/tyres and a tyre repair kit.
Taking care of safety are six airbags, forward collision warning, Autonomous Emergency Braking (AEB) front and rear, with front/rear cross traffic alert, lane departure warning with passive steer assist, lane keep with active assist, blind spot monitor, 360-degree view cameras, parking assist, parking sensors, anti-lock brakes with electronic brake-force distribution and brake assist, stability control, traction control and corner braking, among other features. More details in the safety section below.
Our BMW also included three options that detracted from the M4’s comfort and/or taste: $5000 Frozen Portimao Blue paintwork, $7500 M carbon bucket seats and $8500 M Carbon exterior package, upping the total unnecessarily to $197,900 before ORC.
Rivals in the 2+2-seater ragtop arena are few and far between. With no Audi RS5 Cabriolet in existence, Audi only has the S5 Cabriolet from $126,200, but that’s up against BMW’s M440i Convertible from $135,900. There’s more parity with the ageing Mercedes-AMG C 63S Cabrio from $202,177 and softer Lexus LC 500 Convertible from $213,877, while the cheapest Porsche 911 Carrera Cabrio will set you back a cool $262,900.
Seen in that light, it’s fair to say the standard M4 Competition xDrive is in a league of its own – particularly when you factor in the BMW’s ability to more-or-less equal and even exceed the others at their own game. And that’s something the previous version could not achieve.
So, that’s a surprising yes for value.
At $349,900, before on-road costs, the BMW M8 Competition Gran Coupe sits in an interesting part of the upper-luxury, high-performance market, the unifying theme being a forced induction V8 engine under the bonnet.
On price, it lines up almost exactly with Bentley’s twin-turbo Continental GT V8 ($346,268), but that’s a more conventional, two-door coupe.
If it’s four doors you’re after, some compelling options, within shouting distance of the M8’s price, include the supercharged V8 Jaguar XJR 575 ($309,380), twin-turbo V8 Maserati Quattroporte GTS GranSport ($299,990), and the presidentially powerful and imposing twin-turbo V8 Mercedes-AMG S 63 L ($392,835).
But, arguably, the competitor that lines up best in terms of intent, performance, and personality is Porsche’s Panamera GTS ($366,700). You guessed it, a twin-turbo V8, also designed to prowl the autobahn’s left lane.
So, in this exalted company you need to bring your quality and features A-game, and the M8 Competition Gran Coupe doesn’t disappoint.
Running through all the car’s standard equipment would be a tedious exercise, if only for the sheer volume of features, and hopefully, the following highlights package will give you a feel for the level we’re talking about here.
Aside from copious amounts of active and passive safety tech (covered in the Safety section) this brutal Beamer features, four-zone climate control, configurable ambient (interior) lighting, keyless entry and start, ‘Merino’ leather trim covering the seats, doors, dash, M steering wheel, and gearshift, ‘Anthracite’ Alcantara headlining, 20-inch alloy rims, active cruise control, a digital instrument panel, head-up display, and laser headlights.
The electrically-adjustable sports front seats are ventilated and heated, while the leather-trimmed steering wheel, front centre armrest, and even the front door armrests can also be dialled up to a toasty setting.
You can also add a 10.25-inch multimedia display featuring navigation (with real-time traffic updates), Apple CarPlay and Bluetooth connectivity, as well as gesture control and voice recognition. The exterior mirrors are heated, folding, and auto-dimming. The Bang & Olufsen surround sound audio system boasts 16 speakers and digital radio.
There’s also a digital dash display, panoramic sunroof, rain-sensing wipers, soft-close doors, power sunblinds on the rear, and rear side windows, and a l-o-t more. Even in this price range, that standard fit-out is impressive.
Here is a summary of Australian-market outputs and prices for the M3 and M4 convertible autos, with the prices in brackets being approximate inflation-adjusted figures for today.
1999 E36: 236kW/350Nm 3.2L in-line six-cylinder engine (I6), $152,000 ($266,000 in 2022); 2003 E46: 252kW/365Nm 3.2L I6, $158,000 ($240,000); 2008 E93: 309kW/400Nm 4.0L V8, $183,442 ($240,000); 2014 F83: 317kW/550Nm 3.0L twin-turbo I6, $178,430 ($202,000).
In 2022, the G83 M4 Competition lives up to its name in more ways than one, with a 2993cc 3.0-litre double overhead cam direct-injection twin-turbo I6 known as the S58 series, which is itself derived from BMW’s B58 modular family of engines. Its 375kW is delivered at a lofty 6250rpm, while there’s a 650Nm plateau of torque between 2750rpm and 5500rpm.
A kerb weight of 1920kg means the M4’s power to weight ratio is an impressive 195.3kW/tonne, helping its published 0-100km/h time of 3.7s. For a few grand extra, the company will up the top speed by 30km/h, to 280km/h.
BMW says the engine includes cooling and oil supply systems designed for extreme lateral forces at high speeds, while the exhaust uses electrically controlled flaps for a more raucous noise.
Power is channelled to all four wheels continuously via an eight-speed M Steptronic transmission with a trio of shift programs. The AWD system features an active differential to better transmit torque to all four wheels, while drivers can choose one of three, progressively more rear-wheel drive (RWD) biased modes: 4WD, 4WD Sport and 2WD – the latter being a pure RWD set-up.
Other related changes the M4 boasts over regular 4 Series models include special stability and traction control tuning, a double-joint spring strut front axle with unique axle geometry and variable-ratio steering, a five-link rear axle featuring its own kinematics and elastokinematics, M-specific adaptive dampers, a configurable braking set-up according to feel and response, and forged M light-alloy 19-inch alloys up front and 20-inch items out back.
Choosing the AWD-only convertible over the equivalent AWD coupe adds 145kg (and 195kg compared to the RWD coupe), though this is partly offset in two ways over the preceding, folding-hardtop M4 Convertible: firstly, using the soft top drops weight by 80kg; and secondly, while the AWD system does add 50kg, it’s at a lower centre of gravity, thus naturally improving vehicle dynamics.
Which are electrifying, by the way.
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.’
We managed 12.1 litres per 100km in a mixture of urban, freeway and rural-road driving, including plenty of performance testing. This is a two-tonne M4 convertible capable of supercar speeds, after all. In that context, the economy is more than acceptable. No doubt the stop/start engine function (at idle) helps here.
For the record, the official combined-average claim for this Euro 6-rated BMW is 10.4L/100km, for a carbon dioxide emissions average of 237 grams/km. Thanks to a fuel tank that holds 59 litres of 98 RON premium unleaded petrol, it can manage an average of almost 570km between refills.
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.
Marvellously.
Earlier, we said that the previous M4 (and some earlier M3 generations) never hit the dizzy heights the best like the E46 managed.
The reason why is bandwidth. Not WiFi bandwidth, but rather the newfound breadth of capability that the G83 model has acquired.
Yes, while even the slowest examples of previous M3s and M4s remained thrilling, with blisteringly potent acceleration accompanied by a soaring exhaust soundtrack, the post-E46 models seemed to become almost too obsessed with the pursuit of performance. Thunderous V8s and twin-turbo V6s are all good and well, especially when they provide explosive responses, but there’s more to sports cars than sheer bloody-minded speed.
More specifically, though the handling and roadholding were outstanding, the previous M4’s steering didn’t feel as connected or one with the driver, instead seeming a little remote and detached. Conversely, even with adaptive dampers on offer, the suspension (on Australian roads) lacked sufficient isolation from bumps and thumps, and so was never settled or calm. It was all too nervous and edgy, like a drug-addled athlete who’s indulged in too much partying.
Thankfully, the curse is broken with the latest iteration, even in the heaviest and slowest version like our M4 Convertible as tested, pushing out boundaries to thrilling effect once more.
With the newly-simplified and logically presented M performance modes only a push of a button away, the driver now no-longer has to concentrate on what setting they’re in, and instead just immerse themselves in the experience of accelerating, steering, cornering, braking and controlling this incredible sports convertible.
Tremendously strong in regular Road mode, the M4’s performance certainly lives up to the legend, stepping up into the supercar realm when Sport or Track are chosen, hunkering down as it thrusts towards the horizon with relentless speed and determination, accompanied by the gorgeous twin-turbo six’s revs as they soar towards the red line. The ultra-alert eight-speed auto’s operation is equally seamless, displaying uncanny intuition in its selection of the right ratio at exactly the right time.
These are all incremental improvements over what has come before. But what’s really changed is how rock-solid the BMW feels as it belts along at speed, magnetised to the motorway regardless of weather, its new AWD engineering keeping everything steady and planted. No more tetchiness to unnerve the driver.
Which makes the feel and fluency of the chassis even more remarkable, given that now all four wheels are driven. The very opposite of leaden or inert, the superbly weighted steering is instead light and alive in your palms, as you carve through corners with pin-point precision. Some might find it a bit too eager to change direction at first, but we reckon BMW has judged the balance just right. Its sheer agility is as life-affirming for driving enthusiasts as it is immersive. Bravo, BMW.
With so much grip and control, this is not to say that the driver can’t hang the M4’s tail out every-which-way, since the chassis set-up allows for progressive oversteer, even in Road mode, along with as much drifting as your courage allows where safe. As with the best sports cars, the M4 is as steerable from the seat of your pants as it is using the throttle.
Finally, there’s the M Adaptive chassis tune, that at long last broadens the M4’s repertoire from motorway grand tourer and rural-road blaster to city slicker and urban warrior, thanks to the suspension’s ability to better-absorb a much wider array of terrible road surfaces. Comfort now lives up to its name, with the ride – though still firm – no longer hard or crashy around town, ushering in a new level of civility that won’t fatigue or aggravate you or your occupants. We're so happy to report this progress.
One area where BMW might want to keep improving, though, is the abundance of road noise intrusion over certain coarse chip bitumen. While easily muffled by the sweet sounds of the twin-turbo six, banging audio system or dropping the roof, it now seems more obvious that the rest of the car has smartened up so much.
A small fly in an otherwise hugely satisfying ointment.
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.
There is no specific crash-test data for the BMW G83 M4 Convertible.
However, tested in 2021, the G23 4 Series Convertible it’s based on (and tested in European-spec 320d guise) managed to score a five-star ANCAP rating, and performed strongly across each of the main disciplines – adult protection, child protection, vulnerable road-user and safety assist categories, achieving 96 per cent, 86%, 93% and 73% respectively.
Standard safety features includes six airbags (a driver’s knee airbag, dual frontal, side chest and head-protecting airbags for the first row and side chest protecting airbags for the second row), forward collision warning, Autonomous Emergency Braking (AEB) front and rear, with front/rear cross traffic alert, lane departure warning with passive steer assist, lane keep with active assist, blind spot monitor, 360-degree view cameras, parking assist, parking sensors, anti-lock brakes with electronic brake-force distribution and brake assist, stability control, traction control, corner braking and tyre-pressure monitors, BMW LED Laserlight auto high beams with active cornering and light sensitivity and rain-sensing wipers.
The AEB technology is rated for City, Interurban and Vulnerable Road User, according to ANCAP, and works between 5km/h and 210km/h in daytime and nighttime conditions.
There are also two ISOFIX points as well as two top tethers for straps in the rear seats.
The BMW M8 Competition Gran Coupe hasn’t been assessed by ANCAP or Euro NCAP, but that doesn’t mean it’s lacking in terms of active and passive safety tech.
As well as expected crash avoidance features like stability and traction controls, this M8 features the ‘Driving Assistant Professional’ suite which incorporates active cruise control (with ‘Stop & Go’ function) and ‘Night Vision’ (with pedestrian recognition).
Also included are AEB (with pedestrian and cyclist detection), ‘Steering and Lane Control Assistant’, ‘Lane Keeping Assistant’ (with active side collision protection”, an ‘Evasion Assistant’, a ‘Crossroads warning’, ‘Wrong-way warning’, as well as front and rear cross traffic alert.
The headlights are ‘Laserlight’ units incorporating ‘BMW Selective Beam’ (with active high-beam control), there’s a tyre pressure indicator, and ‘Dynamic Brake Lights’ to warn those behind of an extreme braking event.
Plus, M8 Competition owners score complimentary enrollment in the BMW Driving Experience Advance 1 and 2 courses.
To help guide your parking efforts there’s a hi-def reversing camera (with panoramic view monitor), rear parking distance control, and ‘Reverse Assist’. But if all else fails the car can park itself anyway (parallel and perpendicular).
If all of that isn’t enough to avoid an impact, you’re protected by 10 airbags (dual front and front side, knee bags for the driver and front seat passenger, as well as side airbags for the second row, and curtain airbags covering both rows).
An automatic emergency call function contacts the BMW call centre for connection to relevant services in the event of a crash. And as has been the case with BMW since the dawn of time, a first-aid kit and warning triangle are on-board.
We feel here is where the company drops the ball.
Trailing all of its main luxury car rivals (except Porsche) by two years, BMW only offers a three-year/unlimited kilometre warranty, as well as three years of roadside assistance.
BMW says its vehicles’ servicing is condition-based, depending on how they’re driven and other factors, with a dash warning appearing to let the driver/owner know when it’s time. We advise servicing your M4 annually or at every 10,000km, just to be sure.
No capped-price servicing system is offered. However, as long as the first one is paid for before the first service on a new vehicle, the ‘BMW Service Inclusive Basic packages’ is available at extra cost, covering scheduled servicing for three years/40,000km or five years/80,000km.
No prices are published for M models like the M4, but a normal 4 Series costs from $1800 for the five-year/80.000km package. You can bet an M4’s will cost more.
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.
