Summary
BMW 4 series
BMW's new 4 Series blasted onto the world stage with a chonky schnozz on it that only a mother could love. If BMW didn't want anyone to look at the rest of the car, it did a cracking job of it, because everyone had something to say about the big gnashers now grafted to the 4's front end.
I was nervous about it, too, because the 4 Series has always been so elegant and the current 3 Series - on which it is based - is quite nice to look at. It also threatened to overshadow just how good a car the BMW 4 should be, based as it is on the excellent 3 Series.
And, of course, one also had to wonder if a sports coupe like this would be any good around town. Limited vision? Hard to get in and out of? A true four-seater, or just a squishy 2+2? So many questions.Â

Look, I wouldn’t say I’m a trepidacious person by any means, I watched The Exorcist. in my teenage years and managed to get through all of Hereditary without looking away, but the thought of piloting the Mercedes-AMG GT Black Series around Phillip Island is definitely enough to give me pause.
Maybe it’s because of the strictly limited production numbers of the latest Black Series, with only 28 units arriving in Australia?
Or perhaps it’s the $796,777, before on-road costs, price tag?
How about the stonking 4.0-litre twin-turbo petrol V8, directing 567kW and 800Nm to just the rear wheels?
Truthfully, it’s probably a combination of everything, and if the AMG GT Black Series didn’t terrify you just a little, you are either overestimating your abilities as a driver, or don’t have a healthy respect for what the newest Mercedes is capable of.
So, let’s take a brave pill and pull out of pitlane to see how the Mercedes-AMG GT Black Series goes.

Verdict
BMW 4 series7.8/10
The BMW 420i is a terrific car if you're after a bit of style and sophistication. Not everyone will warm to your car's nose, but if you get it de-chromed, like this white one, it really does look pretty good. It's a car that uses very little fuel, moves along smartly and is brimming with a decent amount of tech, even if it could do with a bit more safety gear at this price.Â
I reckon this car is settling well into the automotive landscape and ignoring it because of a few loudmouths think the grille is too big would be a terrible waste.
Mercedes-Benz GT8.4/10
The Mercedes-AMG GT Black Series is a rare beast; in the sense that it’s both unattainable and that it makes you feel like a superhero behind the wheel.
There is more performance on offer than most can hope of using, but the best thing about Mercedes’ latest supercar is its approachability.
In my experience, the more expensive a car gets, the more stressful driving them becomes, but the Mercedes-AMG GT Black Series does something I didn’t think was possible, and turns a near-$1 million supercar into something fun.
Design
BMW 4 series
The internet exploded when it became clear the big kidney grille was for real. To be fair, BMW did itself absolutely no favours by ensuring the photos of the 4 Series made the twin grille look Easter Island statue sized.Â
And it persisted in doing them naked, without number plates to break up the look. In the flesh, it all works, the nose is striking but not completely overblown.Â
BMW coupe elegance reigns supreme in profile, however, with excellent proportions, and even in base form the wheels are the right size. The slim tail-lights and sculpted tail complete the look. It's a car I think most people love looking at. Hardly anyone mentioned the grille.
The cabin is excellent, as are all of the newer BMW interiors. It's not really a base model, given the price, but the mix of Alcantara and synthetic leather is very pleasing.Â
The big screens for the media and instruments headline the cabin with high-tech style and while it's not avant-garde, it's sharp and feels premium, which is just as well.
Mercedes-Benz GT10/10
Most high-performance brands have their hardcore, track-focused models, from the Porsche 911 GT2 RS to the McLaren 765LT and the Ferrari 488 Pista.
For Mercedes-Benz, it’s the Black Series, a badge which could be found in the past on the SLK, CLK, SL-Class, C-Class, but for 2021 it’s now found on the back of the GT supercar.
To differentiate it from the rest of the ‘standard’ Mercedes-AMG GT range, a slew of racecar-like components are added, such as a fixed rear wing (with deployable insert), vented front fenders, extended front splitter and fixed-back seats.
In fact, so different is the Black Series, that the only panel that carries over from the GT is the roof, which is a carbon-fibre component to keep weight down.
Other carbon-fibre bits include the front fenders, front and rear bumpers, and rear hatch.
The most in-your-face addition might be the deeply vented bonnet, designed to evacuate hot air from the engine bay, while the hero 'Magma Beam' orange colour that juxtaposes all the exposed carbon-fibre panels is a real attention grabber.
From the outside, the Mercedes-AMG GT Black Series is bold, brash and in-your-face, but that’s exactly what a race car should be – in my opinion, at least.
I absolutely love how the Black Series looks like a Need for Speed or Forza Horizon video game car brought to life, and will turn heads anywhere you go.
Inside, the Black Series is clad in soft-touch 'Dinamica' and orange contrast stitching across many of the touchpoints such as dashboard, steering wheel and door cards.
And with fixed-back bucket seats, a racing harness and a roll cage, you’d be forgiven for thinking the AMG GT Black Series is all about function over form, but there are small touches to make it easier to live with on the road.
The multimedia touchpad controller falls easily in hand, while the shifter is flanked by an array of light-up buttons to adjust settings like adaptive suspension, exhaust note and rear spoiler angle.
Overall, the Black Series’ cabin is well-laid out like a standard AMG GT, with some nice flourishes to stand it apart.
Practicality
BMW 4 series
As a sports coupe, it's hardly a practical all-rounder but it's not a squishy 2+2 either. The rear seats are sculpted for maximum headroom and have the added bonus of holding onto rear passengers.Â
Six footers won't be super-comfortable but it's bearable for short trips. There are two ISOFIX points back there, too.Â
The front seats electrically fold out of the way for ingress and egress, but it's not an elegant process.
Front-seat passengers score two cupholders and bottle holders in the doors and a black hole for your phone and its wireless charging pad.
The boot takes an impressive 440 litres and the rear seats split and fold like good little soldiers.
Mercedes-Benz GT7/10
As a two-seat coupe, the AMG GT Black Series isn’t the most practical of cars, but then again, it isn’t trying to be.
The cabin is big enough to accommodate six-foot tall (183cm) passengers like myself, though the fixed-back seats are designed to be form-fitting even for slender frames.
Storage options inside include two cupholders and a shallow underarm storage cubby, and that’s about it.
Unlike the standard GT, the Black Series’ doors forgo the small storage pocket – likely to keep weight down.
Opening the boot reveals enough space for a set of golf clubs or a few weekend bags, but not much else.
Mercedes does not list the volume available in the Black Series, but with the inclusion of a rollcage and special reinforcement components to help transfer the downforce of the rear wing to the chassis, it’s safe to assume it is less than the 176 litres offered in the AMG GT.
Price and features
BMW 4 series
The 420i starts at $71,900. That's a fair bit of money, I think you'll agree.
You get 19-inch wheels, a 10-speaker stereo, LED headlights with auto high beam, head-up display, power front seats, lighting package, auto-parking with reverse assistant, synthetic leather and Alcantara interior, 'Live Cockpit Professional' (fully digital dash), wireless phone charging and digital radio.
The massive 10.25-inch touchscreen may be smaller than the 12.3-inch digital dashboard, but it still looks huge. BMW's Operating System 7.0. is a cracking set-up, and you can control it via either touch or the 'iDrive' rotary dial on the console. It also has Apple CarPlay and Android Auto. Both of them, wireless. You don't read that every day.
You also get 'BMW ConnectedDrive', with some remote services that last for three years. The subscription includes things like the endearingly weird 'Caring Car' and the far less weird real-time traffic information.
The 4 Series is available in eight colours. 'Alpine White' is the only freebie while 'Black Sapphire', 'Arctic Race Blue', 'Portimao Blue', 'San Remo Green' and 'Mineral White' are $1538 each (or part of the 'Visibility Package'). 'Tanzanite Blue' and 'Dravit Grey' are a hefty $2962.
My car for the week had the $6300 Visibility Package (metallic paintwork, sunroof, BMW Laserlight, Ambient Light, which is worth it for the amazing Laserlights alone), the $2860 'Comfort Package' (lumbar support, electric boot, heated front seats, 'Comfort Access' with 'BMW Digital Key') and an $800 black pack. All this took the price to $81,860.
Mercedes-Benz GT6/10
Wearing a price tag of $796,777, before on-road costs, the Mercedes-AMG GT Black Series costs more than double the $373,276 GT R coupe, and an eye-watering $343,577 more than last year’s limited-release GT R Pro.
It’s a significant amount of cash for sure (still not enough to buy a decent house in Melbourne’s inner city, though), but, as well as increased performance, you are paying for exclusivity.
The GT is only the sixth model in Mercedes’ long history to wear the Black Series badge, and production of the new model will be limited, though to what extent is currently unclear.
Only 28 units will make it Down Under though, and each is already spoken for.
Weirdly, this makes last year’s GT R Pro rarer with only 15 examples in Australia, while the SLS Black Series was also more exclusive with only seven available locally.
So, what exactly do you get for your extra spend?
Remarkably, the equipment list on the Black Series largely mirrors its GT siblings, including a flat-bottom steering wheel, staggered 19-/20-inch wheels, push-button start, 12.3-inch customisable digital instrument cluster, dual-zone climate control and various driving modes.
Handling multimedia duties is a 10.3-inch multimedia screen with satellite navigation, Apple CarPlay/Android Auto connectivity, digital radio and an 11-speaker sound system.
However, the Black Series adds a few more touches to the cabin to make things feel more special, such as a microfibre-clad steering wheel, fixed-back carbon-fibre seats, orange-stitch detailing, a roll cage and a four-point racing harness.
Though that doesn’t sound like it's enough to justify the huge step up from the GT R, as is the case with most special-edition models, the engine and mechanicals have been given a thorough workover to extract maximum performance from the platform (more on this below).
Under the bonnet
BMW 4 series
The 420i’s 2.0-litre turbocharged four-cylinder, codenamed B48, spins up 135kW/300Nm. Driving the rear wheels through an eight-speed ZF automatic transmission, you'll go from zip to the 100km/h mark in 7.5 seconds, which is brisk, if not staggering.
Mercedes-Benz GT10/10
Powering the GT Black Series is AMG’s ubiquitous 4.0-litre twin-turbo-petrol V8 engine, with a few modifications.
For starters, a flat-plane crank is used for the V8 for improved throttle response, less weight and different firing order that makes it more free revving than the standard engine.
In fact, so different is the engine that Mercedes-AMG has given the Black Series’ powerplant its own internal code, with only three technicians in Affalterbach qualified to put it together.
The result is peak power of 537kW available from 6700-6900rpm, while maximum torque reaches 800Nm, on tap from 2000-6000rpm.
For those keeping track, that’s 107kW/100Nm more than the GT R.
Sending drive exclusively to the rear wheels via a seven-speed dual-clutch automatic transmission, the AMG GT Black Series will accelerate from 0-100km/h in just 3.2 seconds and top out at 325km/h.
Efficiency
BMW 4 series
BMW's official combined-cycle figures seem to be slowly moving towards reality. The 420i's sticker figure of 6.4L/100km was met with an indicated 6.8L/100km, which was excellent going for almost exclusively suburban and urban running.Â
It's a solid result, but being a BMW, it's premium unleaded only for its 59-litre tank.
With my generally unsympathetic (but not psychopathic) right foot, that means a real-world range of over 800km between fills.
Mercedes-Benz GT8/10
Officially, the GT Black Series will consume 13.2 litres per 100km, making it thirstier than the GT R that returns 11.4L/100km.
The GT Black Series will require 98RON petrol and this, coupled with the high consumption average, will mean a big bill at the bowser.
However, as such a focused performance machine, fuel economy in the Mercedes-AMG GT Black Series is less of an important point than something like a charismatic and dynamic engine.
Driving
BMW 4 series
One of the main things that sets a BMW sedan or sedan-based coupe apart is that they're good everywhere, except perhaps in quicksand.Â
As the platform has matured and BMW's persistence with run-flat tyres has yielded improvements in tyre construction, the 3/4 Series platform (and many others - the internal name for the platform is CLAR) has once again become the benchmark for ride and handling.
For some people reading this, that's a lot of blah blah blah but the main point is, it's a terrific thing to drive whether you're dawdling along in traffic, dealing with traffic calming or bombing down your favourite deserted road.
The Bridgestone tyres on the 420i aren't as ultimately grippy and sticky as the alternative rubber on the 430i but they work well in town and are quiet on the 80km/h roads so prevalent in Sydney.Â
The steering is absolutely lovely, providing just the right weight at any given speed and throwing in the road feel to inspire confidence.
Ride around town is compliant but with the whiff of fun if you decide to push things outside of the city.Â
Its capabilities are still more than worthwhile day-to-day, however, because the way it handles the need to duck in and out of spaces in traffic is extremely handy.
The 2.0-litre four-cylinder is as smooth as rival Audi's. It doesn't sound like much (with a few vestigial pops in Sport mode) but it's certainly got the power to get you out of sticky situations and a transmission that's willing to play ball, whether in Sport or Normal.
Without the adaptive suspension of its 430i and M 440i brethren, this is a very smooth, easygoing sports coupe, with just enough sportiness to keep you interested, if you're that way inclined.
Mercedes-Benz GT10/10
We’ve driven some very fast cars before, so make no mistake when we say the AMG GT Black Series is seriously quick.
The right pedal might as well be warp drive on the, Starship Enterprise, because as soon as you floor the throttle, you’re pinned to the back of the race seat and the only reprise comes from lifting off.
Aside from the immense speed, what is – surprisingly – noticeable is the noise, or lack of it.
The flat-plane crank V8’s different firing order means it doesn’t have the same burbly notes as the standard AMG GT, it’s a racier tone. That’s not a bad thing, mind you, just a different note.
And while the flat-plane crank V8 changes the exhaust note, it also makes the engine freer revving and lively.
With 537kW/800Nm on tap, you sort of have to trust the suspension and aerodynamics will do their thing to keep the AMG GT Black Series on the track, and it’s here where I think Mercedes-AMG has pulled off some sort of magic.
The combination of adaptive dampers, active aero, beefed-up anti-roll bars and a unique Michelin Pilotsport Cup 2 R tyre (featuring a silhouette of the Black Series laser etched into the sidewall) results in a terrifyingly capable vehicle at Phillip Island.
I am the first to admit that I am no Lewis Hamilton behind the wheel, I often get on the throttle too early, I can never nail a double-apex corner and my heel-toe-technique could use more work, but behind the wheel of the GT Black Series, I felt like Ayrton Senna’s spirit had taken the wheel on my behalf.
Cornering in the Black Series felt like nothing else, and regardless of what the speedo was saying, the nose of the ferocious GT flagship would just point wherever I wanted it to go.
Luckily the braking system is also up to task – thanks to carbon ceramic units fitted as standard, as well as unique pads and discs.
The brakes bite almost immediately, giving you the confidence to hit the stop pedal at the last moment before tipping into a corner.
I think the biggest compliment I can pay to the Mercedes-AMG GT Black Series is that it increases that narrow band of fun you can have in a supercar.
Sure, a driver with more skill could pilot the AMG GT Black Series with more grace, and finesse it around the corners a little quicker, but the approachability of the performance on offer is amazing.
Nothing feels intimidating, nothing feels unapproachable. The GT Black Series is so communicative that it gives drivers the confidence to feel like a hero around a race track.
If there is any criticism of the car, it’s that its limits are so high they are hard to explore, even on a circuit like Phillip Island, but maybe that takes more skill than I have, or more than just a handful of laps behind the wheel.
Of particular note, too, is that the engine of the Mercedes-AMG GT Black Series is found in the front.
There’s a reason why some exotic supercars will opt for the mid- or rear-engine layout, but Mercedes has managed to craft a front-engine, rear-drive machine that will keep up with the best the world has to offer.
Safety
BMW 4 series
The 4 Series comes with six airbags, ABS, stability and traction controls, forward AEB, forward collision warning, lane-departure warning, reverse cross-traffic alert and reversing camera.
The 4 Series hasn't been tested by ANCAP or Euro NCAP and the 3's five-star rating can only be a guide because of the very different structure of the 4.Â
Sports cars rarely fare well in the sometimes complex rules so carmakers tend to keep them away from the clutches of crash testers.
Mercedes-Benz GT7/10
The 2022 Mercedes-AMG GT Black Series is yet to be assessed by ANCAP or Euro NCAP, and does not wear an official crash-test rating.
Standard safety features do include automatic wipers, automatic high-beam headlights, blind-spot monitoring, adaptive cruise control, driver attention alert, traffic sign recognition and tyre pressure monitoring.
Though the AMG GT Black Series lacks the usual assortment of safety features that you might find on a more mainstream car, like autonomous emergency braking (AEB), it does offer up more track-orientated safety components.
For starters, the seats feature a four-point harness, securing you snuggly into the fixed-back seats. This means you won’t move an inch, even when cornering at ridiculous speeds.
There is also a roll cage to keep the cabin secure in the event of a serious crash. And five airbags are fitted.
Ownership
BMW 4 series
BMW offers a ho-hum length of three years and 100,000km of warranty coverage. Mercedes has gone to five years so one wonders why BMW (and Audi) hasn't joined its German rival.
Servicing is entirely reasonable at $1650 for a five-year/80,000km package that covers the 12 month/16,000km servicing regime.Â
At $330 per service, it includes things many carmakers don't, such as brake fluid and spark plugs.Â
You can go full noise with the 'Plus Package', which costs $4500 and chucks in brake pads, rotors and even windscreen-wiper replacement. That doesn't seem like terribly good value to me unless you drive like a lunatic.
Mercedes-Benz GT9/10
Like all new Mercedes models sold in 2021, the Mercedes-AMG GT Black Series comes with a five-year/unlimited kilometre warranty with roadside assist over that period.
Mercedes’ warranty easily outclasses other premium marques like BMW, Porsche and Audi, who each offer a three-year/unlimited kilometre coverage, and Lexus (four year/100,000km), while matching Jaguar and newcomer Genesis.
Scheduled servicing intervals are every 12 months or 20,000km, whichever occurs first.
Servicing costs for the Black Series were unavailable to us at the time of publishing, but maintenance of the GT coupe will ring the till up at $4750 over three years.
