The launch of the new BMW 4 Series Coupe marks the
arrival of the fourth generation of BMW’s sporty premium mid-size Coupe. The
BMW Concept 4 Series Coupe, which celebrated its world premiere at the NAIAS
2013 in Detroit, previewed the evolutionary development of BMW’s design
language. And now this progression is enshrined in the series-production model.
The BMW 4 Series Coupe represents the epitome of aesthetic appeal and sporty
dynamics in the premium segment and reinforces the company’s claims to
leadership in the international marketplace. Its stylistic features carry the
promise of a powerful presence on the road, stand-out dynamic ability and
unbeatable driving pleasure. Indeed, the new BMW 4 Series Coupe represents a
paragon of balanced proportions and the final chapter in a story of
development. The “4” in its title headlines this new era for the Coupe and
emphasises not only its stand-alone design, but also its even sharper sporting
dynamics, increased exclusivity and clear technical differentiation from the
BMW 3 Series range. At the same time, BMW is using the new nomenclature to
latch onto the fine tradition established by the large BMW 6 Series and BMW 8
Series Coupes.
Athletic elegance, impeccable proportions.
The dynamic proportions of the new BMW 4 Series Coupe
differ significantly from those of the outgoing BMW 3 Series Coupe. Although
only 26 millimetres have been added to the car’s length (4,638 mm), a
50-millimetre longer wheelbase (2,810 mm) and a roofline that now runs 16
millimetres lower than before (1,362 mm) shine a particularly vivid spotlight
on the dynamically stretched coupe outline. These dimensions combine with the
BMW 4 Series Coupe’s BMW-typical short overhangs, long bonnet, set-back
passenger compartment and flowing roofline to produce a silhouette boasting
impeccable visual balance. The athletic appearance of the BMW 4 Series Coupe is
rounded off by the 43-millimetre increase in the Coupe’s width (1,825
millimetres). For the first time, the rear wheel arches mark the car’s broadest
point – a clear statement of dynamic intent. The resultant 45-millimetre-wider
front track (1,545 mm) and full 80 millimetres of extra width at the rear axle
(1,593 mm) promise – before so much as a wheel is turned –further improvements
in the already superlative sporting characteristics for which BMW is renowned.
Eye-catching front end with prominently sporting
contours.
Signature BMW front-end design features, such as the
double-kidney grille and twin circular headlights, identify the BMW 4 Series
Coupe as a BMW without the need for a second glance. Indeed, it is undeniably
keen to show off its close family ties with the BMW 3 Series. However, the BMW
4 Series Coupe displays a more sporting approach to its work, underlining its dynamic
convictions. The car’s head-turning front end is a demonstration of precise
contours and multifaceted surfaces. The eye-catching full-LED twin headlights
(optional), with their hexagonal design, team up with the slightly
forward-slanting BMW kidney grille to form a single stylistic unit and
strengthen the athletic presence of the BMW 4 Series Coupe on the road. Below
the headlight line, the BMW 4 Series Coupe features a large air intake in the
front apron. Its extremely width-accentuating design creates the impression of
a sporty three-way split. On the far left and right-hand edges of the air
intakes are the additional, aerodynamically motivated small vertical apertures
for the Air Curtains. These vents improve the airflow around the outside of the
front wheels and lead to a reduction in fuel consumption at higher speeds.
Flowing lines shape the elegantly sporty silhouette.
Powerfully taut surfaces and precise, sweeping lines
define the athletic outline of the BMW 4 Series Coupe. The gently sloping roofline
– a hallmark coupe trait – creates a smooth transition into the rear, stretches
the car’s overall appearance and elegantly accentuates the sporting profile of
the flanks. Added to which, the shallow, homogeneous side window graphic with
frameless glass and the signature slimline BMW Hofmeister kink at the trailing
edge of the C-pillar generate a dynamic visual tension. Below the windows, the
double swage line – made up of two character lines running alongside each other
– familiar from the BMW 3 Series teams up with the striking door sill line to
strengthen the body’s dynamic wedge shape. The small, shrinking shadow below
the swage line above the rear wheel accentuates the flared rear wing,
emphasising the car’s dynamic potential and hallmark BMW rear-wheel drive.
Located just rearwards of the BMW 4 Series Coupe’s
front wheels are Air Breathers designed to reduce drag around the wheel arches.
Together, the Air Breathers and Air Curtains underline the sporting character
of the car’s design and provide tangible evidence of the innovative aerodynamic
solutions devised by BMW as part of its BMW EfficientDynamics development
strategy.
Prominently flared wheel arches offer a clear window
into even greater sporting ability.
The sporting character of the BMW 4 Series Coupe
extends into the powerful design of the rear. The prominent horizontal lines
and broadly stretched tail lights positioned at the outer edges of the rear
draw extra attention to the muscular wheel arches and wide track. The sharply
angled rear window has a lowering effect on the car’s tail and gives the body
as a whole an even more powerful look. It also shows off the car’s broad
shoulders with satisfying clarity. The L-shaped rear lights of the BMW 4 Series
Coupe blend harmoniously into the car’s overall design. They continue the path
of the swage line from the flanks, creating a seamless link to the rear end.
Exclusivity and dynamic intent dominate the interior.
The interior of the BMW 4 Series Coupe blends sporting
intent and exclusivity to stylish effect. In the front of the cabin, an
approach known as layering – i.e. the clever utilisation of space through the
structuring of lines and surfaces into layers – provides a natural canvas for
the hallmark BMW driver focus, but is careful not to exclude the front
passenger from the action. All the controls central to driving are arranged
ergonomically around the driver and give him or her optimum access to all
functions. Automatic belt feeders, a Sports steering wheel, crystal-clear
circular instruments in black panel look and the freestanding, flatscreen
iDrive monitor underline the sense of functional elegance. The iDrive Touch
Controller – within easy reach on the centre console – and the optionally
fore-and-aft sliding/folding armrest between the front seats add the finishing
touches to the cabin’s exceptional usability and comfort.
The dynamic horizontal lines of the instrument panel
extend into the optional two-tone door and side panel trim, wrapping around the
driver and front passenger in an unbroken sweep and lending the interior an
engagingly dynamic feel. The interplay of surfaces and lines in the car’s side
sections also provides an effective showcase for the typically long coupe doors
and, through the continuation of the accent strip, creates a visual connection
between the front and rear of the interior. In the rear compartment powerfully
contoured seats lend further emphasis to the sporting credentials of the BMW 4
Series Coupe. Recessed head restraints and broad, continuously moulded side
supports give the rear bench the appearance of two separate seats.
In the interests of maximising the car’s variability,
the backrest of the BMW 4 Series Coupe’s rear seat bench can be folded down, as
an option, in a 40:20:40 split and adapted extremely effectively to suit the
requirements of the situation at hand. Folding down the centre segment alone
creates a large through-loading facility, which can accommodate several pairs
of skis or snowboards while still allowing space for four people on board. (A
suitable BMW ski and snowboard bag is available from the BMW Accessories
range.) The boot can also be opened remotely using the optional Smart Opener as
part of the Comfort Access feature. Here, a short movement of the foot under
the centre of the rear bumper is all it takes to raise the tailgate.
Individual equipment variants.
High-class material combinations, exclusive colours
and individual equipment variants boasting unbeatable quality of workmanship
define the premium ambience on board the new BMW 4 Series Coupe. As well as the
basic trim level, whose material and colour concept accentuates the more
classical side of the car’s character, customers have a choice of three other
equipment combinations and an M Sport package with which to add individual
stylistic touches to the car’s exterior and interior. The Sport Line, Modern
Line and Luxury Line embody different takes on the car’s character, adapting
the design and colour scheme for the kidney grille and air intakes, exterior
mirror caps, Air Breathers and side window graphic, trim strips in the front
and rear apron, door sill strips, model badges on the front side panels, and
range of wheel rims to set the car apart externally from the basic trim level.
Sport Line: The Sport Line adds extra depth to the dynamic
repertoire of the BMW 4 Series Coupe with a selection of eye-catching exterior
body features in high-gloss black. Added to which, the standard high-gloss
black B-pillars and black wrap-around window strip lend the car’s sporting
character even greater punch. Nine strikingly moulded high-gloss black kidney
grille slats in a chrome-coloured surround lend the front end a particularly
sporty and alert look. The three black air intakes in the front apron and the
likewise gleaming black Air Breathers, meanwhile, draw the eye to the car’s
aerodynamic features. 18-inch or 19-inch (optional) light-alloy wheels –
depending on the model – in twin-spoke design provide an extra dose of sporting
theatre. From the rear, the BMW 4 Series Coupe with Sport Line can be
identified by the black trim strip level with the rear apron and the black
exhaust tailpipe embellishers. Inside the car, the contrast between black and
red accents, such as the red trim rings in the inner circle of the instrument
dials and red contrast stitching on the sports steering wheel, provides the
requisite sporting flair. An optional extended equipment variant including
coral red leather sports seats, red door panel trim and a red lower section for
the instrument panel can be specified exclusively for the BMW 4 Series to take
its sporting ambience to another new level.
Luxury Line: Discreet high-gloss chrome touches lend the exterior
of the BMW 4 Series Coupe a particularly elegant and exclusive appeal. 11
intricate kidney grille slats with chrome-coloured fronts and matt black sides,
two high-gloss double bridges in the front apron’s outer air intakes and
chrome-coloured Air Breathers all offer classy touches. The gleaming chrome
window surround is another visual highlight, while special 18-inch or
(optionally) 19-inch light-alloy wheels in multi-spoke design emphasise the
extravagance of the Luxury Line. The BMW 4 Series Coupe Luxury Line can be
recognised from the rear by a stylish, high-gloss chrome strip in the rear
apron and the chrome exhaust tailpipe embellishers. The interior also stands
out with various chrome elements, such as the surround for the audio and air
conditioning system. High-gloss wood strips, leather seats with distinctive
stitching and a choice of two upholstery variants in four classically elegant
colours highlight the exclusivity of the Luxury Line. Exclusively available as
an option for the BMW 4 Series, Ash Grain anthracite fine wood trim surfaces
and a Pearl Gloss Chrome metal inlay round off the Luxury Line features.
Modern Line: High-quality matt chrome exterior trim elements
define the contemporary aesthetic of the Modern Line, while the BMW kidney
grille with 11 slats in matt chrome, the satinated aluminium Air Breathers, the
surrounds for the outer air intakes and the trim strip in the rear apron
continue the theme. The standard window surround in satinated aluminium draws
attention to the window graphics and blends in seamlessly with the trim
elements at the front and rear. 18-inch or (optionally) 19-inch turbine-style
light-alloy wheels lend a fresh angle to the exterior design, while the
light-coloured dashboard coupled with a steering wheel in dark oyster (both
also available in black) create a very special feeling of space. Leather
upholstery or cloth-leather combinations in oyster or black, and a choice of
four trim surfaces with accent strips in Pearl Gloss Chrome, ensure an
appealing interplay between materials.
M Sport package: Customers keen to shine a particularly bright
spotlight on the stand-out dynamic qualities of the new BMW 4 Series Coupe will
find the M Sport package a tempting proposition. As well as an aerodynamic
package, including numerous body components (front apron with large air intake,
rear bumper with diffuser, side skirts), and BMW Individual High-gloss Shadow
Line trim, the exclusive optional exterior paint shade Estoril Blue metallic
ensures an unmistakably sporty appearance and unbeatable road presence – an
effect underpinned by 18- or (optionally) 19-inch light-alloy wheels in hallmark
M design. Inside the car, features such as M door sill finishers, an M leather
steering wheel and an M driver’s footrest shape the sporty yet elegant
ambience. The driver and front passenger can settle into the Hexagon/Alcantara
sports seats with M piping and royal blue contrast stitching offered
exclusively as part of the M Sport package. Technical features of this package
include M Sport suspension and the optional M Sport brakes in contrasting blue
paint finish.
Driving dynamics: Sporty handling properties underpin
an involving driving experience.
The keen dynamics and supreme handling of the new BMW
4 Series Coupe are dominant themes in its engaging driving experience. To
satisfy even the most demanding expectations of a sporty coupe, the BMW chassis
engineers have pulled out all the stops, allowing the sporty two-door car to
give full rein to its talents at any speed and under a variety of conditions.
This required another round of improvements to the recognised qualities of its
predecessor in terms of precision, lightness and agility, further sharpening
the car’s profile as a pure driving machine. The new BMW 4 Series Coupe is
therefore one of the sportiest series-produced models in the BMW line-up,
setting new dynamic standards in its segment.
Hallmark BMW set-up makes the difference.
The new BMW 4 Series Coupe benefits from BMW’s
customary approach of splitting steering and drive forces between the front and
rear axle, which creates the ideal platform for dynamic driving
characteristics, impressive directional stability and agile handling. It also
has 50:50 weight distribution, which likewise sets it apart from its rivals.
When you add to the mix its extremely low centre of gravity, bespoke chassis
set-up and intelligent lightweight construction concept, the result is an
exceptionally dynamic overall package which will even sate the appetite of
customers with a passion for sporty driving.
Significantly lower centre of gravity.
The new BMW 4 Series Coupe has an even clearer
sporting brief than the outgoing BMW 3 Series Coupe and displays an immediate
road presence to match. This is down in no small part to the longer,
2,810-millimetre wheelbase (+ 50 mm) and wider track – 1,545 millimetres at the
front and 1,594 millimetres at the rear (+ 45/+ 80 mm). As standard, the BMW 4
Series Coupe also sits 10 millimetres closer to the asphalt than the latest BMW
3 Series Sedan. This helps to bring the car’s centre of gravity down below 500
millimetres, i.e. significantly lower than its predecessor’s. As these figures
show, new BMW 4 Series Coupe drivers can look forward to an alluring package of
assured roadholding, agile handling and enhanced precision and feedback.
However, these dynamic qualities do not come at the cost of comfort, confirming
the sporting two-door’s status as a car equipped to meet the varied challenges
of everyday use.
A rigorous focus on sports performance.
The chassis construction of the new BMW 4 Series Coupe
is based on that of the latest BMW 3 Series Sedan, although its springs and
damping, axle kinematics and elastokinematics have all been tailored precisely
to the hugely engaging character of the new Coupe. Indeed, the chassis
engineers have managed to make further improvements to the agility and accuracy
offered by the chassis, thanks to modification and fine-tuning of variables
such as the camber angle, the track and the roll centre. Last but not least,
special body strengthening elements in the front section of the car help to
further enhance steering precision and feedback.
Double-joint tie bar front axle with anti-roll bar.
The front axle of the new BMW 4 Series Coupe combines
maximum stiffness with minimum weight. Aluminium torque struts, wishbones and
swivel bearings bring a substantial reduction in unsprung masses. At the same
time, the absence of torque steer allowed the engineers to optimise the
kinematics of the double-joint axle in favour of agility and dynamism.
Adjusting the position of the control arms in the swivel bearings from their
arrangement on the latest BMW 3 Series Sedan gives the car a 19-millimetre
lower roll centre, which has a positive effect on driving dynamics. An
additional strut between the front axle subframe and body sill creates a
stiffer overall connection between the front wheels and the car’s main
structure, so the transverse forces generated on entry into corners are
transferred to the car more directly. The BMW 4 Series Coupe therefore responds
far more directly to the driver’s steering commands and displays more sporting
characteristics and greater agility overall. And that means it threads its way
through corners with supreme ease and even greater precision.
Five-link rear axle enhances the car’s engaging
character.
The rear axle of the new BMW 4 Series Coupe plays a
critical role in boosting the car’s dynamic ability. But that does not mean
comfort has been neglected. This construction is based on the proven five-link
concept, and its elastokinematics have been tuned specially for this sports
coupe. In addition, extra-wide mounts and supports on the wheel carriers for
track and camber, slightly repositioned pivot points, ultra-stiff control arms
and axle subframes, and the use of thrust arms to connect the suspension with
the body all provide an excellent basis for an extremely sporty and dynamically
exceptional overall set-up. The result is precise and assured wheel location,
and therefore unbeatable directional stability in any driving situation. Clever
aerodynamic features around the rear axle also do their bit for driving
dynamics.
Servotronic as standard, variable sports steering
optional.
A standard feature of the new BMW 4 Series Coupe is
Electric Power Steering, complete with the Servotronic function providing
speed-sensitive power assistance. The system’s clearly defined mapping results
in sharper steering feel and feedback. Precision, accuracy and direct responses
are thus among the steering attributes that help define the Coupe’s sporting
character, while torque steer is conspicuous only by its absence. The new BMW 4
Series Coupe can be equipped with variable sports steering as an option. This
uses different steering ratios depending on the amount of lock applied. Only a
small amount of steering effort is required for manoeuvring, for example, while
unbeatable tracking and straightline stability at high speeds are guaranteed.
There are also benefits for the car’s handling attributes, e.g. when
lightning-quick evasive manoeuvres are required.
Powerful braking system with lightweight construction.
In keeping with its dynamic performance capability,
the new BMW 4 Series Coupe comes equipped with powerful swing-calliper or
fixed-calliper brakes and large, inner-vented brake discs. The callipers on the
front axle are made from aluminium. As well as boasting low unsprung masses,
the brakes also stand out with their outstanding heat tolerance, excellent wet
braking performance, ease of use and excellent feel. A brake pad wear indicator
and the Brake Drying function are standard on all models.
Intelligent lightweight construction concept and
aerodynamic fine-tuning.
The new BMW 4 Series Coupe’s intelligent lightweight
construction concept makes a significant contribution to the car’s dynamic
qualities. The use of high- and ultra-high-strength multi-phase steels and
tailored blanks maximises the body’s strength, without driving up the weight.
Components which are central to rigidity are made from micro-alloyed steels.
The body’s front end is 60 per cent more rigid than that of the outgoing BMW 3
Series Coupe and so has benefits beyond agility and steering precision alone.
Most impressively, the new BMW 4 Series Coupe tips the scales at up to 45 kg
less than its predecessor, depending on the engine and equipment specified,
despite having grown significantly in terms of dimensions.
The new BMW 4 Series Coupe highlights its aerodynamic
qualities with a Cd (drag coefficient) of 0.28. Optimisation measures carried
out at the front apron and the rear of the car have earned the two-seater a
lift coefficient to match the sporting figures of the current BMW M3 Coupe.
Another factor here is the design of the underbody: the aerodynamically
optimised structure incorporates smooth panels extending to the sides, under
the engine compartment shield and around the front section of the exhaust
tunnel. Together, they seal the underbody to an unprecedented degree.
Air Curtains and Air Breathers.
The aerodynamic fine-tuning process takes in every
area of the body. For example, the now familiar BMW Air Curtains in the front
apron generate a veil of air which reduces turbulence – and therefore drag –
around the front wheels. The aerodynamically designed wheel arches and the air
deflectors in front of them contribute to the dynamic qualities of the new BMW
4 Series Coupe. The new Air Breathers positioned rearwards of the front wheel
arches divert some of the air flowing through the wheel arches, thereby
reducing air resistance. They work particularly effectively in combination with
the Air Curtains.
M Sport suspension, adaptive suspension and M Sport
brakes.
The M Sport suspension included as part of the M Sport
package can also be ordered separately. It works with a firmer spring/damper
set-up and stiffer anti-roll bars, and its kinematics/elastokinematics have
also been tweaked to suit the new BMW 4 Series Coupe. M Sport suspension also
includes 18-inch or (optionally) 19-inch M light-alloy wheels. Alternatively,
customers may prefer to specify lowered, adaptive suspension – with its focused
sporting set-up and electronically controlled dampers – which adjusts the damper
mapping to the road surface and driving situation at hand. The driver can also
use the Driving Experience Control switch to vary the basic suspension settings
between the more comfortable and the sportier ends of the scale, according to
personal preference. For performance-minded customers, BMW offers the M Sport
brakes. The team of aluminium fixed callipers (four-piston at the front,
two-piston at the rear) and generously sized discs combine extremely low weight
with very short stopping distances.
Driving Experience Control switch with ECO PRO mode:
extra-sporty or economic driving modes at the touch of a button.
The new BMW 4 Series Coupe also offers drivers the
ability to give the overall character of the car a sportier or more comfortable
edge, depending on the driving situation or their personal preferences. Using
the Driving Experience Control switch with ECO PRO mode on the centre console,
drivers can select their desired mode – ECO PRO, COMFORT, SPORT or SPORT+ (in
conjunction with the Sport Line or M Sport package). Each of these predefined
set-ups activates different settings for the relevant powertrain and suspension
components.
In SPORT mode, for example, throttle response is even
faster and the steering becomes noticeably more direct. If the automatic
gearbox is fitted, the gearshift points are also altered to provide a
significantly sportier drive. Depending on the car’s specification, different
settings can be selected for the powertrain and chassis components. In SPORT+
mode, the Dynamic Stability Control thresholds are raised and Dynamic Traction
Control (DTC) is activated. The electronic limited-slip function for the rear
differential can then provide extra-sporty acceleration out of corners or sharp
bends.
Powertrain: Powerful engines maximise dynamic
performance.
Owning a coupe reflects a driver’s passion for elegant
lines, sports performance and high-class dynamics. And the state-of-the-art
powertrain technology under the skin of the new BMW 4 Series Coupe ensures it
delivers an engaging driving experience that satisfies even the most demanding
expectations.
Longitudinally front-mounted, in-line engines sending
their power to the rear wheels see BMW putting its faith in a proven and
time-honoured drive concept that delivers unbeatable driving pleasure. All the
engines available for the new BMW 4 Series Coupe use BMW TwinPower Turbo
technology, which combines sporty performance characteristics with exceptional
efficiency. Added to which, all the engines meet the EU6 exhaust gas standard.
Available from launch are a six-cylinder in-line petrol engine for the BMW 435i
Coupe, a four-cylinder petrol unit for the BMW 428i Coupe and a four-cylinder
diesel for the BMW 420d Coupe. These state-of-the-art engines not only imbue
the BMW 4 Series Coupe with outstanding acceleration and elasticity, they also
join forces with the car’s intelligent lightweight construction concept to lay
on further improvements in driving dynamics and lower fuel consumption.
Power is transferred from engine to road via a
six-speed manual gearbox as standard, although all engine variants can also
link up with an eight-speed Sports automatic as an option. Both gearboxes work
in tandem with the fuel-consumption-reducing Auto Start Stop function. The BMW
xDrive intelligent, all-wheel-drive system can be ordered as an option from
launch for the two petrol-engine variants.
Elite athlete: six-cylinder in-line engine for the BMW
435i Coupe.
The new BMW 435i Coupe gives full value to
performance-minded drivers thanks to a straight-six petrol engine that
impresses with instantaneous power delivery, the thirst for revs you would
expect from BMW, outstanding refinement and exceptional efficiency. Equipped
with High Precision Direct Injection and Valvetronic fully variable valve control,
the 3.0-litre engine with aluminium crankcase develops maximum output of 225
kW/306 hp between 5,800 and 6,000 rpm. Peak torque of 400 Nm (295 lb-ft) is
generated as low down as 1,200 rpm and remains on tap up to 5,000 rpm. The
promise of pure dynamics contained within those figures is made true out on the
road.
The sporting performance characteristics of the potent
six-cylinder power unit allow it to accelerate the new BMW 435i Coupe from 0 to
100 km/h (62 mph) in just 5.4 seconds (a mere 4.9 seconds with xDrive) on the
way to an electronically limited 250 km/h (155 mph) top speed. The six-cylinder
unit belies its impressive performance with extremely low fuel consumption and
emissions figures. Average fuel consumption is between 7.9 and 8.1 litres per
100 kilometres (35.8 – 34.9 mpg imp) and CO2 emissions range from 185 to 189
grams per kilometre (EU test cycle, depending on the tyre format specified).
And the new BMW 435i Coupe is even more economical when fitted with the
optional eight-speed Sports automatic gearbox. Here, the flagship 4 Series
Coupe achieves combined fuel consumption of just 7.3 – 7.4 litres per 100
kilometres (38.7 – 38.2 mpg imp), while CO2 emissions are pinned to between 169
and 172 grams per kilometre.
Low in weight, high on performance: the four-cylinder
engine for the BMW 428i Coupe.
Spirited power delivery, impressive torque, high
maximum revs and low weight are the key qualities of the 2.0-litre
four-cylinder turbocharged engine, which fits in seamlessly with the dynamic concept
of the new BMW 4 Series Coupe. Here again, BMW’s technology package – including
High Precision Direct Injection, twin-scroll turbocharging, Double-Vanos
variable camshaft control and Valvetronic fully variable valve control – lays
on impressive performance potential combined with low fuel consumption and
emissions.
The cutting-edge, four-cylinder petrol engine
generates maximum output of 180 kW/245 hp at 5,000 – 6,500 rpm and peak torque
of 350 Nm (258 lb-ft), which the driver can access between 1,250 and 4,800 rpm.
The new BMW 428i Coupe harnesses these sporty performance attributes to sprint
from 0 to 100 km/h (62 mph) in 5.9 seconds and has an electronically limited
top speed of 250 km/h (155 mph). The engine translates each dab of the accelerator
into forward propulsion instantaneously and conjures up compelling power
delivery from the moment it spins above idle all the way into the upper regions
of its engine speed range along an almost linear curve. The average fuel
consumption of the BMW 428i Coupe in the EU test cycle stands at just 6.6 – 6.7
litres per 100 kilometres (42.8 – 42.2 mpg imp), and CO2 emissions of 154 – 156
grams per kilometre (depending on the tyre format specified) are similarly low.
The optional eight-speed Sports automatic gearbox also opens up further
potential for fuel savings in the BMW 428i Coupe; combined fuel consumption of
between 6.3 and 6.4 litres per 100 kilometres (44.8 – 44.1 mpg imp) and CO2
emissions of 147 – 149 grams per 100 kilometres represent a compelling proposition.
Powerful and efficient: the four-cylinder diesel
engine in the BMW 420d Coupe.
It is a number of years now since BMW first proved
that diesel engines can make an extremely attractive choice of power source for
coupes as well. Today, this is a widely recognised truth and diesel engines in
no way conflict with the sporting aspirations of this breed of car. The new BMW
420d Coupe sees the latest-generation four-cylinder diesel engine put forward
another compelling case with its imposing torque, exceptional refinement and
outstanding efficiency – achieved without impinging on the car’s involving
driving experience. This state-of-the-art diesel unit with composite aluminium
crankcase sets a variety of benchmarks. The latest-generation common rail direct
injection technology, turbocharger with variable turbine geometry and precise
solenoid valve injectors ensure instantaneous throttle response and impressive
punch, combined with extremely low fuel consumption and emissions.
With maximum output of 135 kW/184 hp at 4,000 rpm and
peak torque reaching 380 Nm (280 lb-ft) between 1,750 and 2,750 rpm, the new
BMW 420d Coupe displays an extremely dynamic turn of pace. The sprint from 0 to
100 km/h (62 mph) is dealt with in just 7.5 seconds and the agile diesel can
accelerate up to 240 km/h (149 mph) if required. Average fuel consumption of
4.7 – 4.8 litres per 100 kilometres (60.1 – 58.9 mpg imp) and CO2 emissions
between 124 and 126 grams per kilometre (EU test cycle, depending on the tyre
format specified) complete the profile of the new BMW 420d Coupe as a powerful
and efficient athlete equipped with one of the cleanest and most economical
diesel engines in its class.
Six-speed manual gearbox as standard.
Easy gear changes, precise shift travel and optimum gear
spacing are the stand-out features of the sporty six-speed manual gearbox for
the new BMW 4 Series Coupe. For drivers with sporting tendencies, the interface
where the power from the engine is relayed to the drivetrain is key to
maximising the car’s dynamic performance. The manual gearbox uses its high
shift quality to open the door to powerful sprints and rapid, short bursts of
speed, and also plays its part in helping to reduce fuel consumption.
Eight-speed Sports automatic available as an option.
Its extra gears, extraordinarily rapid gear changes
and outstanding shift comfort make the wonderfully capable, eight-speed
automatic gearbox the perfect fit for the dynamic overall concept of the new
BMW 4 Series Coupe. With only small increases in rpm between gear changes, the
ideal gear is on hand in virtually any situation out on the road. Added to
which, a host of innovative technical features and exceptionally high internal
efficiency ensure that powerful acceleration and assured, short bursts of speed
are possible with no additional fuel consumption over the manual gearbox. Last
but not least, the eight-speed automatic’s intelligent control technology
enables extremely fast shift and reaction times and direct downshift
capability. Customers with a passion for sporty driving are therefore also
extremely well catered for, especially as they can also flick through the gears
using paddles on the steering wheel. Drivers can choose between normal and
sport modes using the Driving Experience Control switch.
BMW xDrive: intelligent all-wheel drive available as
an option.
As an alternative to classical rear-wheel drive, the
BMW 435i Coupe and BMW 428i Coupe can also be specified with BMW xDrive
intelligent all-wheel drive. As well as sharing all the traditional virtues of
all-wheel-drive systems – such as superior traction, unbeatable safety and the
optimum transfer of engine power to the road – BMW xDrive also reduces the
oversteer or understeer you would normally expect through corners. In the
process, it enhances agility and precision, e.g. when turning into corners or
when accelerating strongly out of them. The all-wheel-drive system even
compensates for abrupt load alterations with effortless ease, allowing it to
raise the dynamic qualities of the new BMW 4 Series Coupe to another level.
Available from this autumn: the BMW 420i Coupe, BMW
430d Coupe and BMW 435d Coupe, plus two BMW xDrive options.
In the latter part of the year BMW will add another
petrol variant and two powerful sports diesels to the new 4 Series Coupe
line-up. The BMW 420i Coupe will develop 135 kW/184 hp and can be combined with
BMW xDrive, if desired. The intelligent all-wheel-drive system will also be
available from the autumn for the BMW 420d Coupe. Vast reserves of torque and
unbeatable efficiency are the signature features of the two six-cylinder diesel
engines, bringing an extra dose of dynamic verve to the BMW 4 Series Coupe. The
BMW 430d Coupe will produce 190 kW/258 hp and maximum torque of 560 Nm (413
lb-ft). And topping the range will be the BMW 435d Coupe (exclusively available
with xDrive). With maximum output reaching 230 kW/313 hp and peak torque of 630
Nm (465 lb-ft), it is poised to set the pace in the world of sporty diesel
engines.
BMW EfficientDynamics: Higher performance, lower fuel
consumption.
The engaging driving pleasure available on board the
new BMW 4 Series Coupe is a product of outstanding economy as well as
impressive dynamics. This is down to the BMW EfficientDynamics development
strategy, the results of which are incorporated into virtually every area of
the sporty two-door model. In addition to petrol and diesel engines with
optimised fuel economy, the new BMW 4 Series Coupe’s highly efficient
transmissions, intelligent lightweight design, optimised aerodynamics and
further efficiency-promoting measures secure its status as a winner not only in
terms of sporty and dynamic qualities, but also with regard to its enviable
fuel consumption and emissions figures.
State-of-the-art petrol and diesel engines forge a
perfect alliance of power and efficiency.
The petrol engines available for the BMW 4 Series
Coupe stand out with their exceptional power, free-revving character and
refinement, combined with peerless efficiency. To this end, the engines feature
a range of innovative technical solutions, brought together into a complete
package of technology. They include BMW TwinPower Turbo technology with
twin-scroll turbocharging, High Precision Direct Injection, Double-Vanos
variable camshaft control and Valvetronic fully variable valve control. In
addition, these low-friction engines feature a lightweight, all-aluminium
crankcase.
The BMW TwinPower Turbo diesel units also represent
the very latest in BMW engine technology. The current line-up of diesels
features latest-generation, common rail direct injection, turbocharging and an
all-aluminium construction to deliver high torque, smooth running and
unsurpassed efficiency. In addition, the diesel engines come equipped with
advanced BMW BluePerformance technology, combining a diesel particulate filter
and oxidation catalytic converter with a NOX storage catalyst to ensure the
diesel engines already meet the future EU6 emissions standard today.
Optimised power transfer also offers potential for
fuel savings: the six-speed manual gearbox and eight-speed Sports automatic.
Both the six-speed manual gearbox and eight-speed
Sports automatic stand out with their optimised efficiency, compact
construction and reduced weight. In the case of the eight-speed automatic,
minimised torque converter slip, high internal efficiency, low friction losses
and intelligent transmission control create substantial potential for fuel
savings. New BMW 4 Series Coupes fitted with the automatic gearbox option
therefore offer identical or even lower fuel consumption and emissions.
Auto Start Stop, Brake Energy Regeneration, ECO PRO
mode, coasting mode and Proactive Driving Assistant.
As standard, the new BMW 4 Series Coupe comes with the
Auto Start Stop function, which can also team up with the eight-speed automatic
gearbox. Another standard feature is Brake Energy Regeneration, which ensures
that – as far as possible – power for the vehicle’s electrical system is
generated during braking and coasting. ECO PRO mode plays a particularly
effective role in helping the BMW 4 Series Coupe driver to maintain an
efficient and economical driving style. As well as tweaking the accelerator’s
responses and the engine management system, ECO PRO mode also reaps the rewards
of intelligent energy and climate management. The system gives the driver tips
and ideas – tailored to the driving situation at hand – on how to reduce fuel
consumption even further through adjustments to his or her responses at the
wheel. In conjunction with the optional automatic transmission, a coasting mode
is now also available for the first time. In ECO PRO mode, this function
decouples the powertrain as soon as the driver backs off the accelerator at
speeds between 50 and 160 km/h (approx. 30 – 100 mph), allowing the car to
glide along with no engine braking effect and burning minimal fuel. The BMW 4
Series Coupe boasts a further innovation in the form of the Proactive Driving
Assistant. Likewise in the interests of reducing fuel consumption, this
function advises the driver of the ideal moment to ease off the accelerator
when approaching corners and speed-restricted zones as well as towns and
roundabouts.
On-demand operation of ancillary units saves energy.
The new BMW 4 Series Coupe’s ancillary components also
play a role in the car’s intelligent energy management. Examples include the
on-demand coolant pump, the map-controlled oil pump and the Electric Power
Steering system, which only consumes electricity when steering assistance is
actually required. The special air conditioning compressor works on the same
principle. As soon as the driver switches the air conditioning off, the belt
drive to the compressor is disconnected to minimise power drain.
Intelligent lightweight design further reduces fuel
consumption and CO2 emissions.
The use of lightweight materials makes a significant
contribution to efficiency and agility, and helps to give BMW cars their
impressive dynamic capability. Indeed, intelligent lightweight design can be
found in every area of the development process and its reach extends to every
component. As well as the use of plastics and cutting-edge composite materials,
the increased deployment of aluminium components in the engine and chassis
construction has also reduced the weight of the corresponding assemblies. The results
are impressive: although the new BMW 4 Series Coupe has grown in terms of
dimensions, it is between 20 and 45 kilograms lighter than its predecessor.
BMW ConnectedDrive: Wide range of mobility services
and new driver assistance systems enhance safety and comfort.
BMW ConnectedDrive provides renewed evidence of its
technical leadership and underscores the innovative character of the new BMW 4
Series Coupe with new functions and an unmatched combination of standard and
optional driver assistance systems and mobility services. The intelligent
link-up between passengers, their vehicle and the outside world ensures
unbeatable levels of on-board comfort, infotainment and safety.
Navigation System Professional: Touch Controller takes
over the reins.
The new generation of the Navigation System
Professional impresses with its new design and optimised operating system. It
has a significantly greater breadth of functionality and a high-resolution,
contrast-rich colour display. The familiar menu navigation has been retained,
although extra functions have been added. The graphics of the previous user
interface have been completely overhauled and the navigation system’s maps
given 3D elements. The central Control Display is operated in the familiar way
using the ergonomically perfectly positioned iDrive Touch Controller in the
centre console, which now has an integral new, touch-sensitive surface and
proximity sensor technology for even easier use. Users can now use their finger
to write characters into every text input panel on the touchpad can and switch
between handwriting and the conventional rotate-and-press method at any time.
Plus, the ring cursor in the Navigation System Professional’s interactive map
can also be moved around using the touchpad. This makes selecting a POI, for
example, an intuitive and efficient process.
The smart way to avoid congestion: Real Time Traffic
Information (RTTI).
Available as an option, the RTTI (Real Time Traffic
Information) system uses the mobile phone network and a SIM card built into the
vehicle for ultra-fast transmission of very detailed data. The real time
information, which is taken into account when calculating routes and possible
diversions, is relayed to the vehicle with unrivalled reliability and
precision. RTTI covers motorways and dual carriageways, as well as country
roads and main and side roads in urban areas. Data is additionally obtained
from local authority traffic management systems to provide precise information
on traffic density. Coloured road markings on the map view visualise the
current traffic flow states. The information is refreshed minute by minute and
the updates cover a constantly expanding road network taking in many European
countries.
High-res projection in colour: the Head-Up Display.
One of the highlights of the new BMW 4 Series Coupe is
the latest-generation full-colour Head-Up Display, which projects key
information onto the windscreen in sharp resolution to appear directly in the
driver’s field of view. Depending on the vehicle specification, not only is the
current speed displayed, but speed limits and overtaking restrictions are also
flashed up for the driver’s benefit, along with navigation instructions and
various warning messages. The variety of driver assistance systems available
for the new BMW 4 Series Coupe brings the amount of information that can be
shown in the Head-Up Display to a whole new level. The intensity of the
projections adapts automatically to the light conditions and therefore follows
the illumination of the cockpit dials. The precise positioning of the
projections on the windscreen can also be adjusted easily using the iDrive
Controller.
Driving Assistant Plus warns the driver of a possible
collision with pedestrian.
A camera fitted to the rear-view mirror scans the scene
in front of the vehicle and uses image processing to detect any people or
vehicles within its field of vision. When it recognises a looming risk of
collision with the vehicle in front, the system produces an acute audible
warning and a visual signal appears in the instrument cluster or the optional
Head-Up Display (if specified) to alert the driver that he or she is drawing
too close. Should a collision be unavoidable, automatic moderate hazard braking
is actuated. And if, during urban journeys in sufficient light conditions, the
system detects a potential collision with a pedestrian, it warns the driver in
good time and, if necessary, triggers automatic hazard braking. In both cases –
in addition to the warnings – the vehicle’s brakes are automatically primed for
emergency braking and the activation thresholds of the Brake Assist system are
lowered. As part of the Driving Assistant Plus option, the Lane Departure
Warning system is optionally available.
A system of many talents: Active Cruise Control with
Stop & Go function.
The latest development stage of the familiar Active
Cruise Control with Stop & Go function (ACC Stop&Go) uses a
front-mounted camera on the rear-view mirror in addition to the full-range
radar sensors to provide an enhanced interpretation of the traffic situation
ahead. When driving in slow-moving traffic or traffic jams, the driver is able
to safely move along with the flow of traffic and let the vehicle’s automatic
systems handle the tasks of stopping, pulling away again and approaching
junctions where there are already vehicles waiting ahead. Combining radar and
video data in this way improves detection of other vehicles and cuts the
system’s reaction time. If a vehicle ahead brakes very sharply in free-flowing
traffic, requiring the driver to take action, he or she is prompted to do so by
a two-stage warning. Active Cruise Control with automatic distance control is
now available at speeds between 30 km/h and 210 km/h (19 mph and 130 mph). The
intelligent cruise control function remains active at speeds above 210 km/h
(130 mph).
In conjunction with the Navigation System Professional
and Navigation System Business, Speed Limit Info helps to keep the driver
informed of the speed limit for the current stretch of road. The front-mounted
camera ensures that additional signs or temporary restrictions – at roadworks,
for example – are taken into account. Information on speed limits or overtaking
restrictions then appears in the instrument cluster or Head-Up Display.
Using sensors and camera monitoring: Lane Change and
Lane Departure Warning systems.
Among the convenience and safety-enhancing assistance
systems on offer are Lane Change Warning and Lane Departure Warning, with the
latter only available as part of the Driving Assistant Plus option. These
systems employ radar sensors and camera monitoring to alert drivers to
potential collision risks when changing lane or if they veer out of lane
unintentionally, and also issue a warning when driving too close to the vehicle
ahead.
LED headlights with glare-free High Beam Assistant.
The BMW 4 Series Coupe is available with the option of
full-LED headlights (xenon as standard), which provide a further safety boost
when driving at night. The bright white light they emit illuminates the road
ahead with an exceptional intensity. Together with the glare-free High Beam
Assistant, Adaptive Headlights with cornering lights and variable headlight
distribution, they set the benchmark. With high beam activated, the headlights
are partially masked as and when required in order to eliminate the danger of
dazzling vehicles as they approach. However, the High Beam Assistant can also
adapt to the traffic situation by switching to low beam on one or both sides.
Superb overview not just when parking: Surround View, Side
View, Top View and BMW Parking Assistant.
In addition to the rear view camera and Park Distance
Control, customers are also able to opt for the Surround View function with
Side View and Top View, which provides a bird’s-eye view of the BMW 4 Series Coupe
and the area around it, enabling the driver to carry out precise manoeuvres in
tight spaces. If the car is moving at under 20 km/h (12 mph), the Side View
function can additionally be activated to allow the driver to keep an eye on
cross-traffic.
Convenience is further enhanced by the BMW Parking
Assistant system, which is able to manoeuvre the car into parking spaces
parallel to the direction of travel. All the driver has to do is operate the
accelerator and brake pedal while the BMW Parking Assistant takes care of the
steering.
Active Protection monitors the driver’s behaviour at
the wheel.
The Active Protection safety package is now even more
extensive thanks to the addition of the Attentiveness Assistant. The system’s
electronics analyse driving behaviour on the basis of various onboard signals.
If the system detects an increased frequency in the telltale signs of fatigue
build-up, the Control Display prompts the driver to take a break by displaying
a coffee cup symbol.
The Active Protection safety package with extended
protection measures and the Emergency Call function with automatic vehicle
location help passengers to mitigate the consequences of an accident, should
the worst come to the worst. Active Protection is activated shortly after the journey
begins, ready to pull the driver and front passenger belts tight and close the
side windows and sunroof if the car enters a critical pre-crash scenario. If
the system detects an impending collision and senses that a crash is
unavoidable, the car will be decelerated automatically and held at a standstill
with its brakes locked. This significantly reduces the likelihood of – or
entirely forestalls – a second collision.
Pure infotainment: further services from BMW
ConnectedDrive.
High-performance interface technology provides
top-of-the-range infotainment capability that enables the driver and passengers
to make extensive use of external mobile phones and music players. Users are
furthermore able to access selected products from BMW Online. The latest-generation
Navigation System Professional features a full speech recognition function and
optimised voice control system to complete the portfolio of office functions
offered by ConnectedDrive. The dictation function uses the full speech
recognition system to enable drivers, for the first time, to dictate text
freely and compose short text-based messages simply by saying what they wish to
write. Internet-based services, as well as calendar entries and text-based
messages, can still be viewed in the Control Display of the iDrive operating
system and read out via the Text to Speech function. In addition, passengers
can access their personal music library on their smartphone or music player.
The BMW Connected app allows in-car use of AUPEO!, web radio and social
networks such as Facebook and Twitter, while the My BMW Remote app can be used
to lock and unlock the vehicle, for example, or to remotely operate an
auxiliary heating system. Finally, information and office services, along with
travel and leisure planners using the Google Maps and Panoramio services,
further increase levels of individual convenience aboard the new BMW 4 Series
Coupe.
