• 2021 BMW 4 Series Coupé - Everything You Need to Know

Yes, it does have the bucktooth grille

LISTEN 07:06

This is it, ladies and gentlemen: the new 2021 BMW 4 Series Coupé, scheduled to make its market debut in October 2020. And here’s all the essential info about it because, let’s face it, there’s more to it than that gaping front grille we’ve seen in so many leaks prior to this official unveil.

BMW 4 Series Coupe - On the Outside

Yes, it has the bucktooth grille. So let’s just get over it, as a lot of internet space will be dedicated to comments on this particular design cue and why BMW went ahead with it exactly as previewed by the Concept 4 prototype. That said, here’s how BMW motivates its existence on the new 4er:

"As a defining element of the front end, the grille stands confidently at its centre. With its upright kidneys connected in the centre, it reprises a design feature from the company’s past – one shared with legendary brand classics, such as the BMW 328 and BMW 3.0 CSi – and adds its own modern twist."

Other than the polarizing grille, the new 2021 4 Series now stretches to 4,768 millimeters (128 millimeters longer than the model it replaces).

It’s also wider at 1,852 millimeters (27 millimeters more than the previous 4er) and taller at 1,383 millimeters (6 millimeters on top of the outgoing 4 Series). Wheelbase, too, takes a hike by 44 mm and now measures 2,851 millimeters.

Elsewhere, the 4er looks like a proper sports car born and bred in Bavaria. It’s got your short front overhangs, look coupé-y doors, and that extremely desirable flowing roofline we’re seeing (unfortunately) on more and more SUVs these days.

BMW 4 Series Coupe - On the Inside

Right from the first peek, you’ll instantly recognize the 2021 4 Series’ interior as that of a modern-day BMW. There’s no mistake here.

The overall layout is there to serve the driver and the driver only with a strong flavor of performance, clear-cut lines, and high-quality materials.

Mind you, the 4er is supposed to be a lot fancier than the 3 Series and below, and as far as press photos go, that’s what we’re getting here.

Among the main highlights here we can lay out the following:

  • sports seats
  • sports leather steering wheel (standard)
  • acoustic glass windscreen
  • Start/Stop button on the center console, near the gear selector
  • rear seats fitted with read restraints

On top of these features, customers can tick the box next to BMW’s M Sport package Pro. What it does, basically, is apply the finishing touches that hint even more at the new 4er’s sportiness and it comes to complement the M Sport treatment:

  • larger front air intakes
  • 18-inch M light-alloys
  • redesigned rear apron
  • M Sport suspension
  • knee pads on the sides of the center console
  • Cerium Grey metallic body paint
  • M Carbon exterior components

with the likes of:

  • 19-inch M alloy wheels
  • eight-speed Steptronic Sport gearbox
  • rear spoiler
  • Harman Kardon sound system
  • engine noises fed into the cabin

On launch, the range-topping 4 Series will be the M440i xDrive Coupé, powered by a 3.0-liter inline-six mill good for 369 horsepower (275 kilowatts) between 5,500 and 6,500 rpm and 500 Newton-meters (369 pound-feet) of torque between 1,900 and 5,000 rpm.

The unit is also gifted with 48V mild-hybrid tech that adds to the mix a starter-generator providing an extra boost of 11 horsepower (11 kilowatts).

Power reaches all four wheels through an eight-speed Steptronic gearbox and from there to the asphalt via BMW’s xDrive setup. In this attire, the M440i xDrive Coupé needs 4.5 seconds to zap through the 0-100 kph (0-62 mph) interval on its way to a top speed of 250 kph (155 mph).

Every model is fitted as standard with the aforementioned eight-speed Steptronic transmission and diesels get the mild-hybrid tech, too. Oh, and the gearbox gets a Sprint function, which we’re told that fiddles with engine and shift mapping for "maximum dynamism to mid-range acceleration and overtaking maneuvers." Essentially, you’ll be able to overpass the car in front quickly, thus remaining for less time on the oncoming lane.

BMW 4 Series Coupe - Technology

As you’d imagine, there’s a lot of tech baked into the new 4 Series. For starters, the standard multimedia setup is the Live Cockpit Plus based on an 8.8-inch display operated via the iDrive rotary joystick and an instrument cluster wrapped around a 5.1-inch color screen.

BMW’s Operating System 7 is also present inside the new 4er. The icing on the cake, however, is the BMW Live Cockpit Professional which mixes a 12.3-inch screen and a 10.25-inch display. It’s also compatible with Apple CarPlay and Android Auto.

BMW 4 Series Coupé - Final Word

If you ask us, the jury is still out on the bucktooth grille. By that we mean that we are still waiting to see the 4 Series in the metal before striking the final judgement, however, BMW is well aware of the fact that this design choice will get the people talking and generate a lot of hype not just for the 4 Series but for the brand itself.

In all fairness, nobody expects the 4 Series to sell like hotcakes - not to the amount the 3 Series or the 5 Series do - so besides it acting as a marketing tool that gets people talking, that radical front end might get what we like to call the Cybertruck effect, as in customers might actually want it because it’s new, courageous to some extent, and to some, quite revolting.

We do have one question, though, and that’s whether the incoming M4 will get it too. We guess we’ll just have to wait and see.

Tudor’s first encounter with cars took place when he was only a child. Back then, his father brought home a Trabant 601 Kombi and a few years later, a Wartburg 353. At that time, he was too young to know how they worked and way too young to drive them, but he could see one thing – each of them had a different ethos and their own unique personality. As time went on, he started seeing that in other cars as well, and his love for the automobile was born.  Read full bio
About the author

The new BMW 4 Series Coupé has arrived, and it is more distinctive and
sportier than ever. The overall vehicle concept behind the two-door car –
from its proportions and bespoke design features to the model-specific
chassis tuning – displays a rigorous commitment to a richly engaging driving
experience. The spotlight on dynamic driving pleasure puts clear water
between the new BMW 4 Series Coupé and the latest BMW 3 Series Sedan
and gives it a significantly sharper character than its predecessor.
The new BMW 4 Series Coupé was developed with the aim of redefining
the essence of driving pleasure in the premium midsize segment. Its aura
of athleticism and exclusivity sees it following in the BMW brand’s coupé
tradition – shaped by a succession of legendary sporting machines –
which now stretches back almost 90 years. The makeup of the
new BMW 4 Series Coupé range reflects the emphasis placed on
dynamic potency in the car’s conception. At market launch in October 2020,
the BMW M440i xDrive Coupé – powered by a 275 kW/374 hp six-cylinder in-
line petrol engine (fuel consumption combined: 7.1 – 6.8 l/100 km [39.8 –
41.5 mpg imp]; CO 2 emissions combined: 163 – 155 g/km) – will take its
place at the top of the range. It will be joined initially by a pair of four-cylinder
petrol engines and a four-cylinder diesel. The plan is then for two six-cylinder
in-line diesel engines to be added to the line-up in March 2021, and the
more powerful of these two units will be fitted in another BMW M model.
The new BMW 4 Series Coupé will be built at BMW Plant Dingolfing.
Exterior design: an exclusive blend of elegance and dynamism.
The appearance of the new BMW 4 Series Coupé brings both the familiar
styling of BMW’s sporty two-door models and the brand’s new design
language to the fore. A small number of crisp lines and the use of clear,
generously sized surfaces come together into a body design which exudes
unadulterated driving pleasure from every angle.
The dynamically stretched proportions of the new BMW 4 Series Coupé
are the result of greater exterior dimensions than its predecessor. Length
has increased by 128 millimetres to 4,768 mm, width by 27 mm to 1,852 mm
and the wheelbase by 41 mm to 2,851 millimetres. Vehicle height is up by
just 6 mm, to 1,383 millimetres, making the car 57 millimetres lower than
the new BMW 3 Series Sedan. Its tracks have increased in width over theBMW
Page 2
previous-generation model’s – by 28 millimetres at the front and
18 millimetres at the rear – and are also 23 millimetres wider than those
of the latest BMW 3 Series Sedan.
An expressive and distinctive front end with a nose for tradition.
The striking front end of the new BMW 4 Series Coupé shines the spotlight
on its standalone character. The large, vertically emphasised BMW kidney
grille angles forwards and extends down almost to the lower edge of the
front apron. Its standard air intakes have a mesh structure of the sort only
previously seen on M models. As a defining element of the front end, the
grille stands confidently at its centre. With its upright kidneys connected in
the centre, it reprises a design feature from the company’s past – one shared
with legendary brand classics, such as the BMW 328 and BMW 3.0 CSi –
and adds its own modern twist.
The slim headlights of the new BMW 4 Series Coupé reach well into the front
wheel arches. Full-LED headlights are fitted as standard, while Adaptive LED
Headlights with BMW Laserlight are available as an option. This equipment
item also comes with the cornering light and adaptive cornering functions with
variable road illumination optimised for urban and motorway driving. At speeds
above 60 km/h (37 mph), BMW Laserlight increases high-beam range to a
maximum 550 metres and follows the course of the road dynamically.
Elegant and dynamic side view, powerful rear.
The flanks of the new BMW 4 Series Coupé are shaped by precise and tautly
carved surfaces. Short overhangs, slender pillars, long doors with frameless
windows, the slim window graphic and a flowing roofline accentuate its
elegant appearance. The glasshouse – heavily tapered in its rear section –
and muscular shoulders accentuate its powerful stature.
At the rear, too, large and distinct surfaces are the dominant influences.
Slim and stylishly darkened full-LED rear lights with consistently illuminating
light bars underscore the car’s powerful looks.
Interior: driver-focused cockpit, two individual-style rear seats.
Cleanly designed surfaces, high-quality materials and the driver-focused
layout of the cockpit define the premium ambience and singularly
performance-centric interior design of the new BMW 4 Series Coupé. Sports
seats and a newly designed sports leather steering wheel come as standard.
Together with the coordinated design of the instrument panel and door panel
trim, the high-set centre console generates an enveloping environment for
the front seat occupants. The standard acoustic glass for the windscreen
further improves comfort over long distances.BMW
Page 3
The instrument cluster and Control Display in the new BMW 4 Series Coupé
form a large-surface display grouping. The start/stop button for the engine is
now positioned in a classy control panel in the centre console. And the model-
specific rear seats with integral head restraints and pronounced individual-
seat character have been designed to accommodate two passengers.
Engines: upgraded BMW TwinPower Turbo technology and mild
hybrid technology for greater dynamism and efficiency.
The new BMW M440i xDrive Coupé is equipped with mild hybrid technology,
as are the diesel models. Fitting a powerful 48V starter-generator and a
second battery allows far more brake energy to be regenerated and stored.
This energy is used not just for supplying the electrical system, but also for
lightening the combustion engine’s workload and boosting its power.
The starter-generator produces an electric boost effect that instantly puts an
additional 8 kW/11 hp on tap for more dynamic overtaking or acceleration off
the line. What is more, the powerful starter-generator also increases efficiency
by assisting the engine while driving at a constant speed and improves
comfort when the Auto Start Stop and coasting functions are in use.
As well as the 275 kW/374 hp straight-six engine under the bonnet of
the flagship model, there is also a choice of two four-cylinder petrol units,
generating output of 135 kW/184 hp in the new BMW 420i Coupé
(fuel consumption combined: 5.8 – 5.3 l/100 km [48.7 – 53.3 mpg imp];
CO 2 emissions combined: 132 – 122 g/km) and 190 kW/258 hp in the new
BMW 430i Coupé (fuel consumption combined: 6.1 – 5.7 l/100 km [46.3 –
49.6 mpg imp]; CO 2 emissions combined: 141 – 131 g/km). A 140 kW/190 hp
four-cylinder diesel engine powers the BMW 420d Coupé (fuel consumption
combined: 4.2 – 3.9 l/100 km [67.3 – 72.4 mpg imp]; CO 2 emissions
combined: 112 – 103 g/km) and BMW 420d xDrive Coupé (fuel consumption
combined: 4.6 – 4.3 l/100 km [61.4 – 65.7 mpg imp]; CO 2 emissions
combined: 121 – 112 g/km). This particular unit, like the straight-six engine
in the BMW 430d xDrive Coupé (fuel consumption combined: 6.2 l/100 km
[45.6 mpg imp]; CO 2 emissions combined: 146 g/km*), is equipped with
a two-stage turbocharging system. The BMW M440d xDrive Coupé
(fuel consumption combined: 6.7 l/100 km [42.2 mpg imp]; CO 2 emissions
combined: 158 g/km*) also combines two turbochargers of different sizes
to produce superbly eager power delivery. All models comply with the
Euro 6d emissions standard.BMW

Eight-speed Steptronic transmission as standard for all model
variants, with the option of shift paddles and new Sprint function.
This is the first time that all model variants in the BMW 4 Series Coupé
range have been fitted with an eight-speed Steptronic transmission as
standard. The latest version of the automatic transmission goes about
its task of relaying drive torque from the engine with optimised shift
characteristics and even greater efficiency.
The eight-speed Steptronic Sport transmission fitted as standard in the
BMW M models and available as an option for all other model variants offers
even sharper shift dynamics and comes with shift paddles on the steering
wheel. It also has the new Sprint function, which adjusts the engine and shift
characteristics to bring maximum dynamism to mid-range acceleration and
overtaking manoeuvres.
Improved body rigidity and bespoke chassis tuning result in eye-
catching dynamism.
Its model-specific proportions, optimised aerodynamic properties, increased
body rigidity, a centre of gravity 21 millimetres lower than the new
BMW 3 Series Sedan’s, and careful tweaks to the chassis geometry,
mounting and set-up give the new BMW 4 Series Coupé a sporty character
all of its own. An intelligent material mix has been employed to optimise
the weight of both the body and chassis technology. And the bespoke
body struts at the front end and in the rear axle area can also take credit
for the car’s superb handling agility and precision.
The standard and M Sport suspension each incorporate specially tuned lift-
related dampers. Customers can also opt for Adaptive M suspension with
electronically controlled dampers. Variable sport steering is included with
the two optional suspension variants. The new BMW 4 Series Coupé rides
as standard on 17-inch light-alloy wheels. The optional M Sport brakes
are available with a choice of blue or red callipers.
The standard equipment roster for the new BMW M440i xDrive Coupé and
new BMW M440d xDrive Coupé features 18-inch M light-alloy wheels and
an M Sport differential with electronically controlled, fully variable locking
function in the rear differential. This item is also available as an option for
the BMW 430i Coupé and BMW 430d xDrive Coupé in conjunction with
M Sport suspension or Adaptive M suspension.

Premiere: M Sport package Pro for the ultimate in intense driving
The design and equipment lines are also a clear reflection of the
uncompromising focus on dynamic driving pleasure underpinning the overall
vehicle concept. An M Sport model is available as an alternative to standard
specification, comprising features such as extra-large air intakes at the front
and a prominently contoured rear apron, M Sport suspension, 18-inch M light-
alloy wheels, knee pads on the sides of the centre console and other specially
designed interior elements. Exterior accents in Cerium Grey metallic form
a further identifying feature of BMW M models, which can also be specified
with an M Carbon exterior package.
The M Sport package Pro offered for a BMW model for the first time elevates
driving pleasure intensity levels another notch. It takes the features of the
M Sport model and adds items including 19-inch M light-alloy wheels, the
eight-speed Steptronic Sport transmission, a rear spoiler, a sporty soundtrack
fed into the cabin and a Harman Kardon surround sound system. In addition
to this, an extensive selection of M Performance Parts will also be available
from the launch of the new BMW 4 Series Coupé.
Top-class customisation options.
A vast array of optional extras can be specified to inject an individual sense
of style into the car and enhance driving comfort. Cloth/Sensatec upholstery
is available as an alternative to the sports seats’ standard cloth covers, while
there is also the option of Vernasca leather trim, extended BMW Individual
Merino leather trim or BMW Individual full leather trim. As well as electrically
adjustable sports seats and heated seats, climate seats are also now available
for the first time. Also to be found on the options list are BMW Individual
interior trim strips of particularly exquisite quality, a Sensatec-trimmed
instrument panel and a leather-covered BMW Individual instrument panel.
Three-zone automatic climate control and a Storage package come as
standard in the 4 Series Coupé. An auxiliary heating system and ambient
lighting including Welcome Light Carpet can be ordered as options.
The likewise optional tilting/sliding roof has a 24-millimetre-longer glass
surface than on the outgoing model.
The rear backrest in the new BMW 4 Series Coupé has a 40 : 20 : 40 split
as standard and its individual sections can be released and folded flat by
pressing a button in the boot. The boot is able to hold 440 litres of gear.
A trailer coupling that extends and retracts again electrically is available as
an option.BMW
Page 6
Far wider choice of driver assistance systems.
A significantly broader selection of driver assistance systems compared
to the preceding generation of the BMW 4 Series Coupé serves to boost
comfort on long journeys and increase safety in situations where the driver
does not have a clear view. Front collision warning with brake intervention,
Lane Departure Warning including lane return (with steering assistance) and
the Speed Limit Info system are all now included as standard. The optional
Driving Assistant Professional adds a number of features including the
Steering and Lane Control Assistant with new Active Navigation, which
uses navigation data to detect any necessary lane changes. There is also
a new automatic formation of emergency lane function for guiding the new
BMW 4 Series Coupé to the most appropriate side of its lane in tailbacks
on the motorway.
The optional Parking Assistant now also features the reversing assistant,
while Parking Assistant Plus includes the BMW Drive Recorder, which
shoots videos of the vehicle’s surroundings up to 40 seconds in length.
The new-generation BMW Head-Up Display beams driving-related
information onto a projection area enlarged by 70 per cent. The new
3D visualisation of the surrounding area available in conjunction with
BMW Live Cockpit Professional shows graphics of the vehicle and the traffic
situation in its immediate vicinity in the fully digital instrument cluster, and
provides information on the possible courses of action offered by activated
driver assistance systems.
New digital services: BMW Maps, BMW Intelligent Personal
Assistant, smartphone integration, Remote Software Upgrade.
The standard-fitted Live Cockpit Plus comprises the iDrive control/operation
system with 8.8-inch Control Display and a Touch Controller, a black panel
instrument cluster centred around a 5.1-inch colour display, multimedia and
navigation systems, two USB ports for data transfer and a WiFi interface.
A built-in SIM card with 4G LTE connectivity and the likewise standard
Connected Package Professional make it possible to use digital services
such as BMW TeleServices and Intelligent Emergency Call, Real Time Traffic
Information with hazard warning, Remote Services and Concierge Services.
The driver and passengers in the new BMW 4 Series Coupé will also benefit
from the enhanced options for intuitive operation and the innovative digital
services brought by the inclusion of BMW Operating System 7.0 in the new
BMW 4 Series Coupé. Display content can be configured individually while
the intuitive multimodal interaction between driver and vehicle can take
place – depending on the situation – via the Control Display’s touchscreen,BMW
Page 7
the proven iDrive Controller, the multifunction buttons on the steering wheel,
voice control or optional BMW gesture control. The BMW Intelligent Personal
Assistant with added functions is also at the customer’s service as a standard
feature in the new BMW 4 Series Coupé.
The optional BMW Live Cockpit Professional, meanwhile, features a fully
digital screen grouping comprising a digital instrument cluster behind the
steering wheel with a screen diagonal of 12.3 inches and a 10.25-inch Control
Display. The fully digital instrument display in the cockpit provides enough
room to accommodate an excerpt from the navigation map, status indicators
for the driver assistance systems or 3D visualisation of the surrounding area.
When it comes to digital services, one of the standout new features for the
new BMW 4 Series Coupé is BMW Maps. As well as calculating routes and
arrival times with remarkable speed and precision, and updating real-time
traffic data at short intervals, the new cloud-based navigation system also
lets drivers enter any word when searching for a destination.
BMW Live Cockpit Plus and BMW Live Cockpit Professional also
come with optimised smartphone integration. Alongside Apple CarPlay,
the operating system for the new BMW 4 Series Coupé now also hosts
Android Auto. Remote Software Upgrade is another new feature that
enables improved vehicle functions and additional digital services to be
imported into the car over the air.
