What's the difference?
It might look like a stealth fighter, but this dramatic example of Aston Martin’s DB11 AMR didn’t fly under anyone’s radar during its time in the CarsGuide garage.
Forget the Duke and Duchess of Sussex, this piece of British royalty caused jaws to drop and camera phones to rise more effectively than any mere ginger celebrity or ex-TV trouper.
AMR stands for Aston Martin Racing, and this performance flagship replaces the ‘standard’ DB11, delivering even more fire under the hood and fury from the exhaust. Aston also claims it’s faster, dynamically superior, and sleeker on the inside.
In fact, the DB11 AMR’s 5.2-litre twin-turbo V12 now produces enough grunt to accelerate it from 0-100km/h in just 3.7 seconds.
More than just a flash Harry, then? Let’s find out.
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 Aston Martin DB11 AMR is fast, capable and beautiful. It has a unique character and charisma its Italian and German competitors can’t match. That said, some important media and safety-tech features are absent. So, it’s not perfect... just brilliant.
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.
For a while there it looked like Aston Martin had fallen into the ‘everything looks the same’ trap, with Ian Callum’s breakthrough DB7 design in the mid-‘90s writing the script for the DB9 that followed, and heavily influencing everything else in the brand’s subsequent portfolio.
But in 2014, Aston’s design chief Marek Reichman sent a message with the DB10 Concept that things were about to change.
James Bond had Q and MI6 to thank for his DB10 company car in Spectre, but real-world Aston Martin customers were soon offered the DB11, which combined the muscularity of Reichman’s work on the ultra-exclusive One-77 from a decade earlier with the swooping, long-nosed proportions of his track-only Vulcan hypercar.
The hallmark of a well executed 2+2 GT is that it looks bigger in photos than it does in reality, and the DB11 is a perfect case in point.
Appearing limo-sized in our accompanying images, the DB11 is in fact 34mm shorter end-to-end than a Ford Mustang, but it’s exactly 34mm wider, and no less than 91mm lower in overall height.
And as any fashionista worth their salt will tell you, dark colours are slimming, and our ‘Onyx Black’ AMR, with gloss black 20-inch forged rims and black ‘Balmoral’ leather interior accentuated the car’s tightly drawn, shrink-wrapped surface treatment.
Signature elements in the shape of a broad, tapering grille, divided side vents, and sharply curved, two-level (smoked) tail-lights clearly identify the DB11 as an Aston Martin.
But the smooth integration of the car’s broad haunches (very One-77), gently tapering turret (optional exposed carbon) and flowing bonnet is masterful and fresh. The dash-to-axle ratio (the distance from the base of the windscreen to the front axle line) is Jaguar E-Type-esque.
And it’s all subtly aero-efficient, For example, the door handles fit flush to the body, the mirror housings double as mini ‘wings’, and the Aston Martin ‘Aeroblade’ system channels air running from carefully crafted openings at the base of the C-pillar, through the rear of the car to generate downforce (with minimal drag) across a lateral vent on the trailing edge of the bootlid. A small flap rises at “high speed” when more stability is required.
The interior is all business, with a simple instrument binnacle showcasing a central 12.0-inch digital speedo-within-tacho combination, flanked by configurable engine, performance and media read-outs on either side.
Aston has form with squared-off steering wheels and the DB11’s is flat on the bottom and decidedly straight on the sides, affording a clear view of the gauges without compromising purpose. A leather and Alcantara trim combination is (literally) a nice touch.
The teardrop-shaped centre stack sits in a slightly recessed section (optionally) lined with ‘carbon-fibre twill’, while the form and function of the 8.0-inch multimedia screen at the top will be immediately familiar to current Mercedes-Benz drivers, as the system, including the console mounted rotary controller and touchpad, is sourced from the three-pointed-star brand.
A band of proudly illuminated buttons across the centre includes gear settings for the transmission and a winged stop-starter in the middle. Strange, then, that the plastic knobs on the adjustable air vents look and feel so cheap and bland. This a $400k-plus Aston Martin, where’s the knurled alloy?
Other highlights include elegant sports seats trimmed in a combination of premium leather and Alcantara. Aston offers various levels of leather and our car’s black ‘Balmoral’ hide is taken from the top shelf.
The key accent colour inside and out on our test example was a screaming lime green, picking out the brake calipers, centre strips on the seats, and contrast stitching throughout the cabin. Sounds awful, looks amazing.
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.
On one hand it’s hard to describe a supercar like the DB11 as practical when its primary purpose is to go ridiculously fast and look incredibly good in the process.
But this is, in fact, a ‘2+2’ GT, meaning a couple of occasional seats have been squeezed behind the front pair to allow obliging contortionists, or more likely small children, to enjoy the ride.
No one is claiming full four-seat capacity, but it’s a trick that has for decades made cars like Porsche’s 911 a more practical choice for high-end, high-performance sports car buyers.
At 183cm I can verify the chronically limited space back there, without anything in terms of connectivity, specific ventilation or storage options provided. Good luck, kids.
For those up front it’s a very different story. First, the doors are hinged to move up slightly as they swing out, which makes entry and egress a more civilised process than it might otherwise be. That said, those doors are still long, so it pays to pre-plan a workable parking spot, and the high-mounted, forward-facing interior release handles are awkward to use.
Storage runs to a box between the seats, complete with a two-stage electrically controlled lid, housing a pair of cupholders, an oddments space, two USB inputs and an SD card slot. Then, there are slim pockets in the doors, and that’s about it. no glove box or netted pouches. Just a small tray for coins or the key in front of the media controller.
And speaking of the key, it’s another strangely underwhelming part of the DB11 AMR’s presentation. Plain and insubstantial, it looks and feels like the key to an under-$20k budget special, rather than the heavy, polished and glamorous item you’d expect to be subtly placing on the table in your preferred three-hat restaurant.
The carpet-lined boot measures 270 litres, which is enough for some small suitcases and a soft bag or two. In fact, Aston Martin offers a four-piece accessory luggage set “expertly tailored to match the car’s specification.”
Don’t bother looking for a spare wheel, an inflator/repair kit is your only option in the case of a puncture.
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.
Head into the $400k new car zone and expectations are understandably high. The DB11 AMR’s is a continent-crushing GT after all, and you want your fair share of luxury and convenience features to go with its huge performance potential.
For $428,000 (plus on-road costs), as well as the safety and performance tech (of which there’s plenty) covered in later sections, you can expect a lengthy standard features list, including a full-grain leather interior (seats, dash, doors, etc), Alcantara headlining, multi-function ‘Obsidian Black’ leather-trimmed steering wheel, electrically adjustable and heated front seats (with three memory positions), heated/folding exterior mirrors, front and rear parking sensors, and 360-degree ‘Surround View’ parking cameras (including front and rear cameras).
Also standard are cruise control (plus speed limiter), sat nav, dual-zone climate control, the electronic instrument cluster (with mode-specific displays), keyless entry and start, a multi-function trip computer, 400-Watt Aston Martin audio system (with smartphone and USB integration, DAB digital radio and Bluetooth streaming), plus the 8.0-inch touch-control multimedia screen.
Then there are LED headlights, tail-lights and DRLs, ‘dark’ grille, headlight bezels, and tailpipe finishers, 20-inch forged alloy rims, carbon-fibre bonnet vent blades and side strakes, dark anodised brake calipers and, to reinforce the car’s motorsport DNA, the AMR logo sits on the door sill plates and is embossed on the front-seat headrests.
Apple CarPlay and Android Auto functionality is a surprising omission, but our test car more than made up for it with a motherload of optional extras including an exposed carbon-fibre roof panel, roof strakes and rear-view mirror caps, as well as ventilated front seats, the vivid ‘AMR Lime’ brake calipers, plus a ‘Dark Chrome Jewellery Pack’ and ‘Q Satin Twill’ carbon-fibre trim inlays to add presence in the cabin. Along with some other bits and pieces this adds up to an as-tested total of $481,280 (before on-road costs).
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.
The DB11 AMR’s (AE31) 5.2-litre, twin-turbo V12 is an all-alloy unit, tuned to deliver 470kW (up 22kW on the old model) at 6500rpm, while retaining the previous DB11’s 700Nm of maximum torque from 1500rpm all the way to 5000rpm.
As well as dual variable camshaft timing, the engine features a water-to-air intercooler and cylinder deactivation, which allows it to run as a V6 under light loads.
Drive goes to the rear wheels via a ZF-sourced eight-speed (torque converter) auto transaxle with column-mounted paddles, recalibrated for faster shifting in more aggressive Sport and Sport+ modes. A limited-slip differential is standard.
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.
Minimum fuel requirement for the DB11 AMR is 95 RON premium unleaded and you’ll need 78 litres of it to fill the tank.
Claimed economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 11.4L/100km, the big V12 emitting 265g/km of CO2 in the process.
Despite standard stop-start and cylinder deactivation tech, in roughly 300km of city, suburban and freeway running we recorded a figure exactly nothing like that, according to the on-board computer we more than doubled the claimed number on ‘spirited’ drives. The best average figure we saw was still in the high teens.
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.
The moment you press the starter the DB11 begins a theatrical performance worthy of the Royal Shakespeare Company.
A high-pitched whine reminiscent of a Formula One air-starter precedes a raucous blast of exhaust noise as the twin-turbo V12 bursts into life.
It’s spine-tingling, but for those wanting to remain on good terms with their neighbours a quiet-start setting is available.
At this point, rocker buttons on either side of the steering wheel set the tone for what follows. The one on the left, marked with a shock-absorber graphic, allows you to scroll the adaptive damping set-up through Comfort, Sport, and Sport+ settings. Its ‘S’ branded partner on the right facilitates a similar trick with the drivetrain.
So, throwing urban serenity out the window, we pushed into maximum attack mode for the engine, and by extension the exhaust, selected D and began to enjoy the first act.
A launch-control function is standard, so purely in the interests of science we explored its function and can confirm it works exceptionally well.
Aston claims the DB11 AMR will accelerate from 0-100km/h in just 3.7sec, which is properly fast, and two tenths of a second faster than the standard DB11 it replaces.
Keep the pedal pinned and two things will happen; you’ll reach a maximum velocity of 334km/h and generate headline news across the country while making your way directly to jail.
With 700Nm available from just 1500rpm, and remaining on tap to 5000rpm, mid-range thrust is monumental and the thundering exhaust note accompanying it is the stuff automotive dreams are made of.
Peak power of 470kW (630hp) takes over at 6500rpm (with the rev ceiling sitting at 7000rpm) and delivery is impressively linear, without a hint of turbo hesitation.
Aston claims the DB11 AMR will accelerate from 0-100km/h in just 3.7sec, which is properly fast.
The eight-speed auto is simply superb, picking up gears at just the right point and holding on to them for exactly the right amount of time. Select manual mode and the slender shift levers on either side of the steering column allow even more control.
In Sport and Sport+ drivetrain modes the howling exhaust is accompanied by an entertaining array of pops and bangs on up and down shifts. Bravo!
The DB11 AMR is underpinned by an ultra-stiff bonded aluminium chassis, with a double wishbone front/multi-link rear suspension set-up attached to it.
Spring and damper rates are unchanged from the previous DB11 and even on enthusiastic back-road runs we found suspension in Comfort and driveline in Sport+ to be the best combination. Flicking the shocks into Sport+ is best kept for track days.
Steering is (speed dependent) electrically power-assisted. It’s beautifully progressive, yet pin-sharp with excellent road feel.
The big 20-inch forged alloy rims are shod with high-performance Bridgestone Potenza S007 rubber (255/40 front – 295/35 rear), developed as original equipment for this car and Ferrari’s F12 Berlinetta.
They combine with the 1870kg DB11’s near perfect 51/49 front to rear weight distribution and standard LSD to deliver confidence-inspiring balance and ferocious power down on (quick) corner exit.
Braking is handled by huge (steel) ventilated rotors (400mm front – 360mm rear) clamped by six-piston calipers at the front and four-piston at the rear. We might have put them under decent pressure from time-to-time, but stopping power remained prodigious and the pedal firm.
In the calm of urban traffic the DB11 AMR is civilised, quiet (if you prefer) and comfortable. The sports seats can be adjusted to grip like a vice at speed or provide more breathing room around town, the ergonomics are spot-on, and despite its striking looks, all around vision is surprisingly good.
Overall, driving the DB11 AMR is a special event, flooding the senses and raising the heart rate no matter what the speed.
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.
Big speed demands serious active and passive safety, and the DB11 comes up short on the former.
Yes, there’s ABS, EBD, EBA, traction control, Dynamic Stability Control (DSC), Positive Torque Control (PTC) and Dynamic Torque Vectoring (DTV); even a tyre-pressure monitoring system, and the surround view cameras.
But more recent crash-avoidance tech like active cruise control, bling-spot monitoring, lane-departure warning, rear cross traffic alert, and especially AEB, are nowhere to be seen. Not great.
But if a crash is unavoidable there’s plenty of back-up in the form of dual-stage driver and passenger front airbags, front side (pelvis and thorax) airbags, as well as curtain and knee airbags.
Both rear-seat positions offer top tethers and ISOFIX anchors for baby-capsule and child-seat location.
The DB11 hasn’t been assessed for safety performance by ANCAP or EuroNCAP.
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.
While Kia leads the mainstream market with a seven-year/unlimited km warranty, Aston Martin sits further back with a three-year/unlimited km deal.
Servicing is recommended every 12 months/16,000km, and an extended, transferable 12-month contract is available, including everything from provision of a taxi/accommodation in the event of breakdown, to coverage of the vehicle at “official Aston Martin organised events.”
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.
