Default 2014 BMW M6 Gran Coupe revealed

From AB











Introducing the All-New BMW M6 Gran Coupe.

The style of BMW's four-door Coupe with performance by BMW M

Woodcliff Lake, NJ – December 12th, 2012, 18:00 (6:00pm) Eastern
Time... In early summer 2013, the all-new BMW M6 Gran Coupe will join
its famous BMW M5 Sedan and M6 Coupe siblings as what is perhaps the
perfect combination of both. The BMW M6 Gran Coupe is an ultra-high
performance, four-door Coupe design with stunning aesthetics,
race-bred technology, and the signature driving character of BMW M
GmbH.

The M6 Gran Coupe is made instantly unique among four-door vehicles by
its bonded-in carbon fiber composite roof panel, similar to the one
found on the M6 Coupe. Between the doors is a cabin of sensational
coupe-like design and first-class materials. The M6 Gran Coupe's
control placement and – equally important – control feel are second to
none. The four-plus-one seating arrangement allows the M6 Gran Coupe
to carry four adults in luxury, and offers maximum seating capacity
for five when needed.

The new M6 Gran Coupe features the most powerful engine ever fitted to
an M production car, a 4.4-liter M TwinPower Turbo V-8 with 560
horsepower and an always-accessible 500 lb-ft of torque. With this
endowment, the rear-wheel drive BMW M6 Gran Coupe practically rockets
from 0-60mph in 4.1 seconds and reaches an electronically-limited top
speed of 155mph in only a few seconds more.

The new BMW M6 Gran Coupe focuses the gargantuan muscle of its engine
on the road through one of the most advanced drivetrains BMW has ever
developed. The high-torque 7-speed M-Double Clutch Transmission
(M-DCT) borrowed from the M5 and M6 Coupe sends power uninterrupted to
the innovative Active M Differential, which in turn perfectly balances
power between the rear wheels. This advanced drivetrain, combined with
truly radical chassis and suspension revisions to the BMW 6 Series
Gran Coupe on which the car is based, ensure that the M6 Gran Coupe's
substantial output is transferred to the ground predictably and
repeatedly.

The High-Revving M V-8 TwinPower Turbo Engine.
The engine of the all-new M6 Gran Coupe has the highest output ever
generated by a BMW M car, and provides a meaningful balance between
ultra-high performance and fuel consumption. The engine's operating
behavior is characterized by traditional M traits like immediate
throttle response and linear power delivery. Additionally, thanks to
turbocharging, the engine features an unusually high and flat torque
curve, sustaining peak torque from 1,500rpm – 5,750rpm. The engine
produces about 10% more output than the M V10 engine which preceded
it, and torque is up by over 30%.

To achieve the performance levels of the new M V-8, the engineers at
BMW M GmbH started with the proven BMW M-developed 4.4-liter V-8
engine from the BMW X5 M and X6 M (internally known as the S63B44
engine) and further developed it for its duty in the latest M5 and M6
models. Internally designated S63B44Tü, this engine uses similar M
Twin Power technology combined with the reverse-flow V-8 layout. The
result is that the high-revving V-8 engine lends a fresh intensity to
the powerful M car experience. The S63Tü develops a peak output of 560
hp (412 kW) at 5,750 – 7,000 rpm (versus 555 hp at 6,000 rpm for the
S63), while its maximum torque of 500 lb-ft (680 Nm) is on tap between
1,500 and 5,750 rpm (versus 500 lb-ft from 1,500 to 5650 rpm for the
S63). The rev limiter intervenes at 7,200 rpm, up 200 rpm from the
original S63 engine and now accessible in each gear until the top
speed limiter intervenes. The rev band, which offers extreme
acceleration between peak torque and the availability of maximum
horsepower, is therefore almost three times as wide as that of the V10
engine from the previous generation of M engines.

As in the M V-8 engine of the X5 M, the two twin-scroll turbochargers
are placed (along with the catalytic converters) in the V-space
between the two cylinder banks in a reverse-flow layout. This layout
results in an unusually compact engine where the intake is moved
outboard and the exhaust inboard – the opposite of traditional
V-engines. The lengths of intake and exhaust tracts are thereby
reduced and their diameters increased, reducing pressure losses -
especially on the exhaust side. A further advantage of the layout is
the short distance between the cylinders' combustion chambers and the
primary catalytic converters; this leads to quicker warm-up of the
catalysts after the engine is started and therefore lower start-up
emissions.
The patented cross-bank exhaust manifold, first introduced in the S63
engine of the X5 M is also employed in the S63Tü, but with slightly
larger tube sizes. This exhaust manifold is a special 8-into-4 setup
that combines the exhaust from two cylinders (on opposite banks) that
are 360Ú of crankshaft rotation apart from each other. Each of
the eight runners is of identical length to ensure perfectly-regular
timing of exhaust gas pulses. The acoustic sound of this engine
arrangement is absolutely signature to BMW M.

Each of the four manifold outlets is fed into each of the four
available scrolls of the two twin-scroll turbochargers. The two
scrolls of a twin-scroll turbo guide each exhaust pulse directly to
the turbine without feedback or interference from the other scroll
(that are fed by cylinders at other points in the combustion process).
Additionally, dividing the gases into two smaller paths (scrolls)
results in higher gas velocity than a single larger path. This
enhances the turbocharger's response, thereby reducing lag. The
crossover manifold is configured so that the second scroll of the
turbo is fed by two cylinders that are 180Ú out of phase with the
first scroll. In this way each turbocharger receives distinct exhaust
pulses every 180Ú of crankshaft rotation (from one of four
cylinders). Furthermore, the two turbos receive exhaust pulses that
are 90Ú offset from each other. The result is that throttle
response is sharpened and turbo lag is reduced to a minimum. The new
engine also sports larger intake runners, larger air to liquid
intercoolers and a tuned exhaust which results in the engine making
power more quickly than previously possible. Finally, the S63Tü uses a
maximum boost pressure of 1.5 bar (21.7 psi) versus 1.2 bar (17.4 psi)
for the original S63 engine.

BMW's efficient High Precision direct fuel injection also plays a
major role in this engine's combination of high performance and fuel
efficiency. High Precision direct injection ensures an extremely
precise supply of fuel to the combustion chambers. Injectors
positioned centrally between the valves within immediate range of the
spark plugs spray fuel into the combustion chambers with maximum
pressure of 200 bar (nearly 3000 psi), providing smooth and clean
combustion. Innovative solenoid valve injectors in the engine use
multiple injections per combustion cycle to achieve an extremely
precise mixture. The fuel also has a cooling effect on the combustion
that allowed the M engineers to endow the engine with a high
compression ratio of 10:1. This high compression ratio contributes to
both performance and efficiency, while reducing exhaust emissions –
and even has a positive effect on engine sound.

Throughout their histories, the hearts of the BMW M5 and M6 have been
high-revving, high specific output engines fed by individual throttle
bodies. The new engine introduces Valvetronic throttle-less intake
system to a BMW M engine – effectively providing 16 individual
throttles.
Valvetronic is BMW's patented, fully variable intake valve control
system that eliminates the need for conventional throttles. Engine
power is instead controlled directly by varying the amount of lift of
the intake valves. Pumping losses are minimized with this system,
resulting in efficiency and torque improvements. Valvetronic has also
sharpened the natural responsiveness of this engine compared to the
V10 engine it replaces.

The M TwinPower technology of the new V-8 engine also includes BMW's
Double VANOS infinitely-variable valve timing system which optimizes
the engine's efficiency and generates high torque at low engine revs.
In addition, a volume-controlled oil pump and a range of other
EfficientDynamics measures deliver an extra boost to efficiency. The
new BMW M6 features both Brake Energy Regeneration and the Auto
Start-Stop function, which automatically switches off the engine when
the car comes to a stop.

The instant power delivery and sustained thrust of the M TwinPower
Turbo V-8 results in acceleration from 0– 60 mph in 4.1 seconds for
the M6 Gran Coupe. Top speed is electronically limited to 155 mph (250
km/h).

7-speed M Double Clutch Transmission with Drivelogic
The new V8 engine M TwinPower Turbo engine is mated to a newly
developed 7-speed double-clutch transmission designed to handle the
high torque and high revving nature of the engine. The M-DCT with
Drivelogic, developed especially for the new M5 and M6, has been tuned
to match the performance characteristics of the engine with the M6
Gran Coupe chassis. It delivers exceptionally fast and clean gear
changes in both Automatic mode (D) and Manual mode (S). No clutch
pedal is required for manual gearshifts and the driver can stay on the
accelerator during gear changes (conditions permitting). The driver
uses the model-specific M gear selector to choose between D and S
modes and to engage Reverse. Comfort is further enhanced by the new
Low Speed Assistance function, which smoothes power delivery in
stop-and-go traffic with a light touch of the accelerator pedal.

The shift lever offers a sequential shift pattern for the manual
gearshift mode. Alternatively, the driver can also change gears using
the shift paddles on the M leather steering wheel, complete with
multifunction buttons. In typical M configuration, the driver pulls
the right-hand paddle to shift up and the left-hand paddle to shift
down. The newest M steering wheel stands out with its smaller rim
diameter and a design that borrows from the double-spoke design of the
M light-alloy wheels.

M-DCT with Drivelogic offers three shift programs in both Automatic
and Manual mode. The driver selects his/her desired mode using the
rocker switch positioned immediately below the shift lever on the
center console. The D1 program is selected automatically when the
engine is started, tailoring gear selection to deliver the most
efficient possible driving style. D2 mode supports moderate cruising
with gear changes carried out according to engine revs and load. And,
to promote a sporty driving style laced with dynamic acceleration and
deceleration, shift times in D3 mode are set up to delay gear changes
until the engine has climbed higher up the rev range, and to downshift
more aggressively when slowing.

Drivers can also adapt the shift characteristics to their requirements
in Manual mode. S1 mode generates comfortable and smooth gear changes.
In S2, the gear changes are completed noticeably faster and
accompanied by significant shift kick at higher revs. S3 is the one to
choose for maximum driving dynamics; it enables even sportier gear
changes and is required to initiate the Launch Control function. When
the DSC stability control system is fully switched off, Launch Control
allows the driver to achieve maximum acceleration from a standstill as
permitted by surface conditions. During Launch Control acceleration,
each gear upshift takes place automatically and at the optimum engine
speed.

Active M Differential.
The Active M Differential in the new M6 Gran Coupe is an
electronically controlled multi-plate limited-slip differential
programmed to optimize traction, stability and sporting character. The
locking force within the differential is varied continuously between 0
and 100%.

The Active M Differential works with high precision and speed. Its
control unit is connected with the Dynamic Stability Control (DSC)
system via FlexRay high-speed data transfer technology and constantly
cross-checks the data collected by its sensors with the feedback from
DSC. It uses this information to calculate the locking force required
to deliver optimum traction and stability during both acceleration and
deceleration. The data recorded by DSC sensors is provided to the
Active M Differential whether the stability control system is in MDM
mode or is switched completely off. The ABS system retains full
functionality in all situations.

In addition to the data provided by DSC, the Active M Differential's
control unit also takes into account the position of the accelerator
pedal, the rotational speed of the wheels and the car's yaw rate.
Every driving situation is therefore analyzed so that any loss of
traction on one side of the car is identified at an early stage. The
degree of axle lock is adjusted as required within a fraction of a
second, enabling wheel spin to be reduced on all surfaces, when the
right and left rear wheel have widely differing friction coefficients
and in tight corners. Optimizing traction in this way also provides
unbeatable driving stability in challenging conditions and allows
impressive acceleration out of corners. The Active M Differential can
also unlock just as quickly to stabilize the car off-throttle.

M-Specific Chassis
Each component in the suspension and chassis of the new M6 Gran Coupe
has been developed based on the extensive race expertise of BMW M
engineers. The aluminum-intensive integral rear axle subframe in the
M6 Gran Coupe is rigidly bolted to the body to maximize body rigidity
and handling precision. Reinforced chassis mountings at the front and
rear axles ensure that dynamic forces are passed through to the body
structure. Specially tuned axle kinematics and newly developed forged
aluminum suspension components boasting high strength and low weight
meet the requirements of everyday driving and the specialized demands
of track use. The result is that the BMW M6 Gran Coupe continues the
BMW M tradition of engineering a chassis that is "faster than the
engine". As with every BMW M car, the engineers carried out the
fine-tuning during extensive testing on the legendary Nürburgring
Nordschleife circuit.
M Dynamic Damper Control (DDC) electronically controlled shock
absorbers are standard on the new BMW M6 Gran Coupe. DDC uses
electro-hydraulic damping force adjustment to provide a set-up suited
to the driving situation and the wishes of the driver. The shock
absorber settings can be adjusted at the touch of a button. In default
Comfort mode, the dampers respond adaptively to the condition of the
road surface and the driver's style. Sport mode activates a noticeably
stiffer damper set-up, while Sport Plus allows further stiffening of
the suspension to achieve maximum longitudinal and lateral
acceleration in ultra-dynamic driving situations.
At the touch of a button, the driver can also select from three
settings for the M-specific Servotronic speed-sensitive hydraulic
power steering. The default Comfort mode keeps steering forces
reasonable when parking or maneuvering, but still provides the M
brand's hallmark direction-changing precision at higher speeds. Sport
ensures the driver enjoys more intense feedback across all speed
ranges. Sports Plus is the lowest level of steering boost that can be
selected.

The new BMW M6 Gran Coupe also uses BMW's most advanced Dynamic
Stability Control (DSC) and Anti-lock Braking System (ABS) that
includes Cornering Brake Control (CBC), Dynamic Brake Control (DBC),
Brake Assistant, Brake Fade Compensation function, a Brake Drying
function and Start-off Assistant. The DSC system has three levels of
operation. The default is "On" which provides the greatest
level of stability and traction control. M Dynamic Mode (MDM) can be
activated to override the default setting by pressing the DSC button
on the center console. This mode allows for very spirited driving – as
on a race track – while still providing a safety net, by raising the
intervention thresholds of DSC. "DSC Off" mode can also be
activated with a long-push of the DSC button for complete deactivation
of the system.
Choice of High-Performance M Brake Systems.

The standard high-performance braking system of the new BMW M6 Gran
Coupe guarantees outstanding stopping power matching the overall
performance of the car. The well-known BMW M compound rotors have been
further improved for the new M5 and M6 family. These rotors thermally
separate the central hub (constructed of aluminum) and the vented /
cross drilled cast iron rotor discs. As a result, the rotors are free
to expand and contract without warping. The diameter of the brake
rotors is 15.7 inches (400 mm) at the front and 15.6 inches (396 mm)
at the rear. The six-piston fixed calipers are radially bolted to the
pivot bearing and are painted blue metallic complete with the M logo.
Together, the M brake system has been tested to provide exceptional
performance and modulation, fade resistance, and pedal feel.

The new BMW M5 and M6 family will be the first cars in the history of
BMW M to be offered with optional M Carbon-Ceramic brakes, which
become available with Spring 2013 production. These new brakes are
without parallel and take the cars' stopping power to a new level –
especially on the race track. The brake rotors measure 16.1 inches
(410 mm) in diameter at the front and 15.6 inches (396 mm) at the
rear. Made from a carbon-fiber ceramic composite, the rotors boast
even greater resistance to heat combined with significantly reduced
rotating masses. The M Carbon-Ceramic brakes are 42.8 lb (19.4 kg)
lighter than the standard brakes, yet the innovative material also
displays exceptional resistance to wear, and the operating life of the
rotors is several times that of conventional equivalents. The optional
M Carbon-Ceramic system also sees six-piston fixed radial calipers at
the front teamed with single-piston floating calipers at the rear. The
M Carbon-Ceramic system can be easily identified through the wheels by
the special gold-colored calipers.

The M6 Gran Coupe features a unique wheel and tire combination with
20-inch M6 Gran Coupe-specific double-spoke forged light alloy wheels
fitted with giant ultra-high performance summer tires, front and
rear.

The Design: An M Showstopper.
Hallmark M design features are always influenced directly by technical
considerations – such as cooling air requirements, chassis geometry,
weight-and-balance, and aerodynamics. This form-follows-function
philosophy opens a design window through which to see the performance
capability of the BMW M6 Gran Coupe. The front of the car is dominated
by its large air intakes, optional Adaptive LED Headlights and an M
kidney grille designed especially for this model. From the side, the M
four-door Coupe is clearly distinguishable from the BMW M6 Coupe
thanks to its rear doors and 113-millimeter (4.45") longer
wheelbase. The low roofline flowing smoothly into the rear, the
shoulder line – which takes in the door openers – and side windows
extending well into the C-pillars accentuate the dynamically stretched
silhouette.

Prominently flared wheel arches draw the eye to a track width specific
to the BMW M6 Gran Coupe. The characteristic M gills, aerodynamically
optimized exterior mirrors, standard BMW Individual High-gloss Shadow
Line package and exclusive 20-inch M light-alloy wheels in
double-spoke design underline the car's distinctive appearance, as
does another M signature – twin exhaust tailpipes positioned on the
outer edges of the rear apron. Also integrated into the rear apron,
and charged with the task of optimizing the exit of airflow from the
car's underbody, is a diffuser made of carbon fiber composite.

Carbon fiber composite, an extremely lightweight, impressively strong
high-tech material is used in the construction of the car's roof panel
as well. Here, the visible carbon structure provides an eye-catching
feature, as does a dynamic recess in the center of the roof. This
recess is referenced stylistically inside the car, the
anthracite-colored Alcantara headliner gaining a central section in
leather.

Emulating the harmonious blend of athletic prowess and elegance
embodied by the exterior design, the distinctive M cockpit fuses
sports car style with generous levels of space and a luxurious
ambience. The driver and front passenger will enjoy M sport seats with
integral seatbelts. And the BMW M6 Gran Coupe's standard specification
also includes Merino Extended leather upholstery. The rear compartment
offers three seats, the backrests of which can split and fold down in
a ratio of 40 / 60 to increase luggage flexibility.

M-specific cockpit design: flawless car control, made-to-measure
luxury.
The interior of the new BMW M6 Gran Coupe brings together the
incomparable combination of the driver-oriented cockpit design of a
sports car with the spaciousness and luxurious feel of a premium
automobile. Merino Extended leather upholstery, door sills with
"M6" lettering, an M driver's footrest, exclusive carbon
fiber interior trim and the headliner in Anthracite Alcantara and
Leather are all standard equipment, as is the iDrive control system
with a 10.2-inch Control Display. This screen is centrally positioned
and like the controls in the central section of the instrument panel,
slightly oriented towards the driver.

M Multifunction sport seats offer the driver and front passenger
optimum lateral support while cornering, but also a high level of
comfort over long distances. The lightweight seats with integrated
belt system have an M-specific design headlined by extremely prominent
cushion and backrest bolsters, head restraints integrated into the
backrests, eye-catching stitching emphasizing the segments of the
seats, and an M logo embossed into the shoulder area. The M
Multifunction sport seats have electric height, fore/aft, side bolster
and backrest angle adjustment, and also come with pneumatically
adjustable lumbar support, a memory function and a manually adjustable
thigh support. The M Multifunction sport seats are fitted with active
head restraints to reduce the risk of whiplash injury in a rear-end
impact.

The M instrument cluster with black-panel technology includes classic
circular instruments in traditional BMW M car style, with red needles
and white illumination, as well as model-specific displays and the M
logo on the rev counter. The shift program currently selected and gear
engaged are shown in the center of the instrument cluster. Feedback
from the drive and chassis settings are also displayed in the
instrument cluster under the tachometer.

Sports Car Cockpit - Custom Tailored M Drive Buttons
On the left-hand steering wheel spoke, the driver has two M Drive
buttons which can be used to call up a pre-configured setup for the
car. For example, the driver can save a sporty configuration on the
"M1" button and a track focused setup (with all driver aids
shut off) on the "M2" button. The set-up selected will
remain activated until it is either cancelled by pressing the button
again or the driver switches to another M Drive setting. Once the
system has been switched off – as when the engine is started – it
reverts back to the default configuration.
The M Drive system in the new BMW M6 Gran Coupe allows the driver to
adjust no fewer than six parameters: the engine management, the
response of the Servotronic steering system, the M-DCT shift program,
the DSC mode, the responses of DDC and the information in the Head-Up
Display. The desired settings can be configured in any combination via
the iDrive menu or by using the M Drive select buttons on the center
console to set the configuration followed by pressing and holding one
of the two M Drive buttons for a few seconds (until the configuration
is stored). For safety reasons, a setup involving setting MDM mode or
"DSC Off" requires confirmation from the driver – by
pressing the M Drive button again – before it can be activated. The
setup configuration selected is shown by a "M1" or
"M2" symbol displayed in the instrument cluster.

M Head-Up Display.
The M Drive configuration also includes the information shown on the
optional M Head-Up Display and projects important information onto the
windshield directly in the driver's field of vision. A full spectrum
of colors is used to display graphics and symbols and the all-color
capability means road sign symbols can be reproduced very
realistically. In addition to a digital speed read-out, the M-specific
version of the Head-Up Display also shows the gear currently engaged
and a color rev counter symbol, complete with Shift Lights.

Developed on the Nordschleife- as with every car ever engineered by
BMW M
BMW has been testing on the legendary Nürburgring Nordschleife since
the 1960s. Every vehicle developed by BMW M since its establishment in
1972 has had to demonstrate its capabilities on the grueling 14-mile
circuit before it was deemed ready.

In the early years BMW conducted tests out of rented facilities. BMW
Motorsport also rented facilities for many years in order to prepare
for race activities like the 24h enduro at the 'Ring.
So dedicated was the company to fully integrating the Nürburgring into
its testing regimen that, in 1991, BMW became the first manufacturer
to establish a permanent testing facility on site. Between 2003 and
2008 the test facility was re-built and enlarged without interrupting
ongoing test activities. This dedication can be felt from behind the
wheel of every product created by BMW M. The new BMW M6 Gran Coupe is
the latest model to demonstrate the results of this dedication.

The new BMW M6 Gran Coupe will reach US Authorized BMW Center
showrooms in early Summer, 2013. US Pricing, final technical
specifications, EPA fuel efficiency estimates, as well as standard and
optional equipment for will be announced closer to the on-sale date.

BMW Group In America

1975. Rolls-Royce Motor Cars NA, LLC began distributing vehicles in
2003. The BMW Group in the United States has grown to include
marketing, sales, and financial service organizations for the BMW

opposite banks) that are 360Ú of crankshaft rotation apart from
each other. Each of the eight runners is of identical length to ensure
perfectly-regular timing of exhaust gas pulses. The acoustic sound of
this engine arrangement is absolutely signature to BMW M.
>
> Each of the four manifold outlets is fed into each of the four

available scrolls of the two twin-scroll turbochargers. The two
scrolls of a twin-scroll turbo guide each exhaust pulse directly to
the turbine without feedback or interference from the other scroll
(that are fed by cylinders at other points in the combustion process).
Additionally, dividing the gases into two smaller paths (scrolls)
results in higher gas velocity than a single larger path. This
enhances the turbocharger's response, thereby reducing lag. The
crossover manifold is configured so that the second scroll of the
turbo is fed by two cylinders that are 180Ú out of phase with the
first scroll. In this way each turbocharger receives distinct exhaust
pulses every 180Ú of crankshaft rotation (from one of four
cylinders). Furthermore, the two turbos receive exhaust pulses that
are 90Ú offset from each other. The result is that throttle
response is sharpened and turbo lag is reduced to a minimum. The new
engine also sports larger intake runners, larger air to liquid
intercoolers and a tuned exhaust which results in the engine making
power more quickly than previously possible. Finally, the S63Tü uses a
maximum boost pressure of 1.5 bar (21.7 psi) versus 1.2 bar (17.4 psi)
for the original S63 engine.
>
> BMW's efficient High Precision direct fuel injection also plays a

major role in this engine's combination of high performance and fuel
efficiency. High Precision direct injection ensures an extremely
precise supply of fuel to the combustion chambers. Injectors
positioned centrally between the valves within immediate range of the
spark plugs spray fuel into the combustion chambers with maximum
pressure of 200 bar (nearly 3000 psi), providing smooth and clean
combustion. Innovative solenoid valve injectors in the engine use
multiple injections per combustion cycle to achieve an extremely
precise mixture. The fuel also has a cooling effect on the combustion
that allowed the M engineers to endow the engine with a high
compression ratio of 10:1. This high compression ratio contributes to
both performance and efficiency, while reducing exhaust emissions –
and even has a positive effect on engine sound.
>
> Throughout their histories, the hearts of the BMW M5 and M6 have

been high-revving, high specific output engines fed by individual
throttle bodies. The new engine introduces Valvetronic throttle-less
intake system to a BMW M engine – effectively providing 16 individual
throttles.
> Valvetronic is BMW's patented, fully variable intake valve control

system that eliminates the need for conventional throttles. Engine
power is instead controlled directly by varying the amount of lift of
the intake valves. Pumping losses are minimized with this system,
resulting in efficiency and torque improvements. Valvetronic has also
sharpened the natural responsiveness of this engine compared to the
V10 engine it replaces.
>
> The M TwinPower technology of the new V-8 engine also includes

BMW's Double VANOS infinitely-variable valve timing system which
optimizes the engine's efficiency and generates high torque at low
engine revs. In addition, a volume-controlled oil pump and a range of
other EfficientDynamics measures deliver an extra boost to efficiency.
The new BMW M6 features both Brake Energy Regeneration and the Auto
Start-Stop function, which automatically switches off the engine when
the car comes to a stop.
>
> The instant power delivery and sustained thrust of the M TwinPower

Turbo V-8 results in acceleration from 0– 60 mph in 4.1 seconds for
the M6 Gran Coupe. Top speed is electronically limited to 155 mph (250
km/h).
>
> 7-speed M Double Clutch Transmission with Drivelogic
> The new V8 engine M TwinPower Turbo engine is mated to a newly

developed 7-speed double-clutch transmission designed to handle the
high torque and high revving nature of the engine. The M-DCT with
Drivelogic, developed especially for the new M5 and M6, has been tuned
to match the performance characteristics of the engine with the M6
Gran Coupe chassis. It delivers exceptionally fast and clean gear
changes in both Automatic mode (D) and Manual mode (S). No clutch
pedal is required for manual gearshifts and the driver can stay on the
accelerator during gear changes (conditions permitting). The driver
uses the model-specific M gear selector to choose between D and S
modes and to engage Reverse. Comfort is further enhanced by the new
Low Speed Assistance function, which smoothes power delivery in
stop-and-go traffic with a light touch of the accelerator pedal.
>
> The shift lever offers a sequential shift pattern for the manual

gearshift mode. Alternatively, the driver can also change gears using
the shift paddles on the M leather steering wheel, complete with
multifunction buttons. In typical M configuration, the driver pulls
the right-hand paddle to shift up and the left-hand paddle to shift
down. The newest M steering wheel stands out with its smaller rim
diameter and a design that borrows from the double-spoke design of the
M light-alloy wheels.
>
> M-DCT with Drivelogic offers three shift programs in both Automatic

and Manual mode. The driver selects his/her desired mode using the
rocker switch positioned immediately below the shift lever on the
center console. The D1 program is selected automatically when the
engine is started, tailoring gear selection to deliver the most
efficient possible driving style. D2 mode supports moderate cruising
with gear changes carried out according to engine revs and load. And,
to promote a sporty driving style laced with dynamic acceleration and
deceleration, shift times in D3 mode are set up to delay gear changes
until the engine has climbed higher up the rev range, and to downshift
more aggressively when slowing.
>
> Drivers can also adapt the shift characteristics to their

requirements in Manual mode. S1 mode generates comfortable and smooth
gear changes. In S2, the gear changes are completed noticeably faster
and accompanied by significant shift kick at higher revs. S3 is the
one to choose for maximum driving dynamics; it enables even sportier
gear changes and is required to initiate the Launch Control function.
When the DSC stability control system is fully switched off, Launch
Control allows the driver to achieve maximum acceleration from a
standstill as permitted by surface conditions. During Launch Control
acceleration, each gear upshift takes place automatically and at the
optimum engine speed.
>
> Active M Differential.
> The Active M Differential in the new M6 Gran Coupe is an

electronically controlled multi-plate limited-slip differential
programmed to optimize traction, stability and sporting character. The
locking force within the differential is varied continuously between 0
and 100%.
>
> The Active M Differential works with high precision and speed. Its

control unit is connected with the Dynamic Stability Control (DSC)
system via FlexRay high-speed data transfer technology and constantly
cross-checks the data collected by its sensors with the feedback from
DSC. It uses this information to calculate the locking force required
to deliver optimum traction and stability during both acceleration and
deceleration. The data recorded by DSC sensors is provided to the
Active M Differential whether the stability control system is in MDM
mode or is switched completely off. The ABS system retains full
functionality in all situations.
>
> In addition to the data provided by DSC, the Active M

Differential's control unit also takes into account the position of
the accelerator pedal, the rotational speed of the wheels and the
car's yaw rate. Every driving situation is therefore analyzed so that
any loss of traction on one side of the car is identified at an early
stage. The degree of axle lock is adjusted as required within a
fraction of a second, enabling wheel spin to be reduced on all
surfaces, when the right and left rear wheel have widely differing
friction coefficients and in tight corners. Optimizing traction in
this way also provides unbeatable driving stability in challenging
conditions and allows impressive acceleration out of corners. The
Active M Differential can also unlock just as quickly to stabilize the
car off-throttle.
>
> M-Specific Chassis
> Each component in the suspension and chassis of the new M6 Gran

Coupe has been developed based on the extensive race expertise of BMW
M engineers. The aluminum-intensive integral rear axle subframe in the
M6 Gran Coupe is rigidly bolted to the body to maximize body rigidity
and handling precision. Reinforced chassis mountings at the front and
rear axles ensure that dynamic forces are passed through to the body
structure. Specially tuned axle kinematics and newly developed forged
aluminum suspension components boasting high strength and low weight
meet the requirements of everyday driving and the specialized demands
of track use. The result is that the BMW M6 Gran Coupe continues the
BMW M tradition of engineering a chassis that is "faster than the
engine". As with every BMW M car, the engineers carried out the
fine-tuning during extensive testing on the legendary Nürburgring
Nordschleife circuit.
> M Dynamic Damper Control (DDC) electronically controlled shock

absorbers are standard on the new BMW M6 Gran Coupe. DDC uses
electro-hydraulic damping force adjustment to provide a set-up suited
to the driving situation and the wishes of the driver. The shock
absorber settings can be adjusted at the touch of a button. In default
Comfort mode, the dampers respond adaptively to the condition of the
road surface and the driver's style. Sport mode activates a noticeably
stiffer damper set-up, while Sport Plus allows further stiffening of
the suspension to achieve maximum longitudinal and lateral
acceleration in ultra-dynamic driving situations.
> At the touch of a button, the driver can also select from three

settings for the M-specific Servotronic speed-sensitive hydraulic
power steering. The default Comfort mode keeps steering forces
reasonable when parking or maneuvering, but still provides the M
brand's hallmark direction-changing precision at higher speeds. Sport
ensures the driver enjoys more intense feedback across all speed
ranges. Sports Plus is the lowest level of steering boost that can be
selected.
>
> The new BMW M6 Gran Coupe also uses BMW's most advanced Dynamic

Stability Control (DSC) and Anti-lock Braking System (ABS) that
includes Cornering Brake Control (CBC), Dynamic Brake Control (DBC),
Brake Assistant, Brake Fade Compensation function, a Brake Drying
function and Start-off Assistant. The DSC system has three levels of
operation. The default is "On" which provides the greatest
level of stability and traction control. M Dynamic Mode (MDM) can be
activated to override the default setting by pressing the DSC button
on the center console. This mode allows for very spirited driving – as
on a race track – while still providing a safety net, by raising the
intervention thresholds of DSC. "DSC Off" mode can also be
activated with a long-push of the DSC button for complete deactivation
of the system.
> Choice of High-Performance M Brake Systems.
>
> The standard high-performance braking system of the new BMW M6 Gran

Coupe guarantees outstanding stopping power matching the overall
performance of the car. The well-known BMW M compound rotors have been
further improved for the new M5 and M6 family. These rotors thermally
separate the central hub (constructed of aluminum) and the vented /
cross drilled cast iron rotor discs. As a result, the rotors are free
to expand and contract without warping. The diameter of the brake
rotors is 15.7 inches (400 mm) at the front and 15.6 inches (396 mm)
at the rear. The six-piston fixed calipers are radially bolted to the
pivot bearing and are painted blue metallic complete with the M logo.
Together, the M brake system has been tested to provide exceptional
performance and modulation, fade resistance, and pedal feel.
>
> The new BMW M5 and M6 family will be the first cars in the history

of BMW M to be offered with optional M Carbon-Ceramic brakes, which
become available with Spring 2013 production. These new brakes are
without parallel and take the cars' stopping power to a new level –
especially on the race track. The brake rotors measure 16.1 inches
(410 mm) in diameter at the front and 15.6 inches (396 mm) at the
rear. Made from a carbon-fiber ceramic composite, the rotors boast
even greater resistance to heat combined with significantly reduced
rotating masses. The M Carbon-Ceramic brakes are 42.8 lb (19.4 kg)
lighter than the standard brakes, yet the innovative material also
displays exceptional resistance to wear, and the operating life of the
rotors is several times that of conventional equivalents. The optional
M Carbon-Ceramic system also sees six-piston fixed radial calipers at
the front teamed with single-piston floating calipers at the rear. The
M Carbon-Ceramic system can be easily identified through the wheels by
the special gold-colored calipers.
>
> The M6 Gran Coupe features a unique wheel and tire combination with

20-inch M6 Gran Coupe-specific double-spoke forged light alloy wheels
fitted with giant ultra-high performance summer tires, front and
rear.
>
> The Design: An M Showstopper.
> Hallmark M design features are always influenced directly by

technical considerations – such as cooling air requirements, chassis
geometry, weight-and-balance, and aerodynamics. This
form-follows-function philosophy opens a design window through which
to see the performance capability of the BMW M6 Gran Coupe. The front
of the car is dominated by its large air intakes, optional Adaptive
LED Headlights and an M kidney grille designed especially for this
model. From the side, the M four-door Coupe is clearly distinguishable
from the BMW M6 Coupe thanks to its rear doors and 113-millimeter
(4.45") longer wheelbase. The low roofline flowing smoothly into
the rear, the shoulder line – which takes in the door openers – and
side windows extending well into the C-pillars accentuate the
dynamically stretched silhouette.
>
> Prominently flared wheel arches draw the eye to a track width

specific to the BMW M6 Gran Coupe. The characteristic M gills,
aerodynamically optimized exterior mirrors, standard BMW Individual
High-gloss Shadow Line package and exclusive 20-inch M light-alloy
wheels in double-spoke design underline the car's distinctive
appearance, as does another M signature – twin exhaust tailpipes
positioned on the outer edges of the rear apron. Also integrated into
the rear apron, and charged with the task of optimizing the exit of
airflow from the car's underbody, is a diffuser made of carbon fiber
composite.
>
> Carbon fiber composite, an extremely lightweight, impressively

strong high-tech material is used in the construction of the car's
roof panel as well. Here, the visible carbon structure provides an
eye-catching feature, as does a dynamic recess in the center of the
roof. This recess is referenced stylistically inside the car, the
anthracite-colored Alcantara headliner gaining a central section in
leather.
>
> Emulating the harmonious blend of athletic prowess and elegance

embodied by the exterior design, the distinctive M cockpit fuses
sports car style with generous levels of space and a luxurious
ambience. The driver and front passenger will enjoy M sport seats with
integral seatbelts. And the BMW M6 Gran Coupe's standard specification
also includes Merino Extended leather upholstery. The rear compartment
offers three seats, the backrests of which can split and fold down in
a ratio of 40 / 60 to increase luggage flexibility.
>
> M-specific cockpit design: flawless car control, made-to-measure

luxury.
> The interior of the new BMW M6 Gran Coupe brings together the

incomparable combination of the driver-oriented cockpit design of a
sports car with the spaciousness and luxurious feel of a premium
automobile. Merino Extended leather upholstery, door sills with
"M6" lettering, an M driver's footrest, exclusive carbon
fiber interior trim and the headliner in Anthracite Alcantara and
Leather are all standard equipment, as is the iDrive control system
with a 10.2-inch Control Display. This screen is centrally positioned
and like the controls in the central section of the instrument panel,
slightly oriented towards the driver.
>
> M Multifunction sport seats offer the driver and front passenger

optimum lateral support while cornering, but also a high level of
comfort over long distances. The lightweight seats with integrated
belt system have an M-specific design headlined by extremely prominent
cushion and backrest bolsters, head restraints integrated into the
backrests, eye-catching stitching emphasizing the segments of the
seats, and an M logo embossed into the shoulder area. The M
Multifunction sport seats have electric height, fore/aft, side bolster
and backrest angle adjustment, and also come with pneumatically
adjustable lumbar support, a memory function and a manually adjustable
thigh support. The M Multifunction sport seats are fitted with active
head restraints to reduce the risk of whiplash injury in a rear-end
impact.
>
> The M instrument cluster with black-panel technology includes

classic circular instruments in traditional BMW M car style, with red
needles and white illumination, as well as model-specific displays and
the M logo on the rev counter. The shift program currently selected
and gear engaged are shown in the center of the instrument cluster.
Feedback from the drive and chassis settings are also displayed in the
instrument cluster under the tachometer.
>
> Sports Car Cockpit - Custom Tailored M Drive Buttons
> On the left-hand steering wheel spoke, the driver has two M Drive

buttons which can be used to call up a pre-configured setup for the
car. For example, the driver can save a sporty configuration on the
"M1" button and a track focused setup (with all driver aids
shut off) on the "M2" button. The set-up selected will
remain activated until it is either cancelled by pressing the button
again or the driver switches to another M Drive setting. Once the
system has been switched off – as when the engine is started – it
reverts back to the default configuration.
> The M Drive system in the new BMW M6 Gran Coupe allows the driver

to adjust no fewer than six parameters: the engine management, the
response of the Servotronic steering system, the M-DCT shift program,
the DSC mode, the responses of DDC and the information in the Head-Up
Display. The desired settings can be configured in any combination via
the iDrive menu or by using the M Drive select buttons on the center
console to set the configuration followed by pressing and holding one
of the two M Drive buttons for a few seconds (until the configuration
is stored). For safety reasons, a setup involving setting MDM mode or
"DSC Off" requires confirmation from the driver – by
pressing the M Drive button again – before it can be activated. The
setup configuration selected is shown by a "M1" or
"M2" symbol displayed in the instrument cluster.
>
> M Head-Up Display.
> The M Drive configuration also includes the information shown on

the optional M Head-Up Display and projects important information onto
the windshield directly in the driver's field of vision. A full
spectrum of colors is used to display graphics and symbols and the
all-color capability means road sign symbols can be reproduced very
realistically. In addition to a digital speed read-out, the M-specific
version of the Head-Up Display also shows the gear currently engaged
and a color rev counter symbol, complete with Shift Lights.
>
> Developed on the Nordschleife- as with every car ever engineered by

BMW M
> BMW has been testing on the legendary Nürburgring Nordschleife

since the 1960s. Every vehicle developed by BMW M since its
establishment in 1972 has had to demonstrate its capabilities on the
grueling 14-mile circuit before it was deemed ready.
>
> In the early years BMW conducted tests out of rented facilities.

BMW Motorsport also rented facilities for many years in order to
prepare for race activities like the 24h enduro at the 'Ring.
> So dedicated was the company to fully integrating the Nürburgring

into its testing regimen that, in 1991, BMW became the first
manufacturer to establish a permanent testing facility on site.
Between 2003 and 2008 the test facility was re-built and enlarged
without interrupting ongoing test activities. This dedication can be
felt from behind the wheel of every product created by BMW M. The new
BMW M6 Gran Coupe is the latest model to demonstrate the results of
this dedication.
>
> The new BMW M6 Gran Coupe will reach US Authorized BMW Center

showrooms in early Summer, 2013. US Pricing, final technical
specifications, EPA fuel efficiency estimates, as well as standard and
optional equipment for will be announced closer to the on-sale date.
