Munich. BMW is set to add another variant of the Coupe and Convertible to the BMW 6 Series line-up with the arrival of the BMW 640d xDrive Coupe and Convertible in spring 2012. Intelligent all-wheel drive – making its debut in the BMW 6 Series – teams up with a six-cylinder in-line diesel engine featuring BMW TwinPower Turbo technology to take driving pleasure to another new level. The combination of a diesel engine and BMW xDrive all-wheel drive, which will also be found in the BMW 640d xDrive Convertible, gives the BMW 6 Series a spread of abilities none of its rivals can match.
The new BMW 640d xDrive Coupe accelerates from 0 to 100 km/h (62 mph)
in just 5.2 seconds. The 230 kW/313 hp diesel
powerplant uses
BMW TwinPower Turbo technology to ensure
outstanding efficiency, and joins forces with the standard-fitted
eight-speed Sports automatic gearbox to deliver exceptionally low fuel
consumption and emissions. The xDrive system distributes the power
generated by the engine precisely between the front and rear wheels as
the situation demands. Pulling the strings behind the scenes is an
electronic control unit which links xDrive up with the DSC (Dynamic
Stability Control) system to ensure unbeatable traction, maximum
safety, top-class handling and optimum power development in all
weather and road conditions. The average fuel consumption of the BMW
640d xDrive Coupe stands at 5.7 – 5.8 litres per
100
kilometres / 48.7 – 49.6 mpg imp (in the EU test cycle,
depending on the tyre format), while CO2 emissions are 149 –
153 grams per kilometre.
Six-cylinder in-line diesel engine with BMW TwinPower Turbo technology in the BMW 6 Series.
The instantaneous responses and pulling power of the diesel unit fitted in the BMW 6 Series enable it to do everything required of an engine fitted in a car with a sharp sporting focus. The output characteristics, acoustic profile, low vibrations and efficiency of the six-cylinder unit offer clear evidence of BMW’s expertise in the development of diesel engines.
Rewinding a generation, the introduction – for the first time – of a diesel variant into the previous BMW 6 Series likewise lent an extra dimension to the range. The new BMW 6 Series adds further lustre to the alluring profile of the exclusive and sporty, yet also economical, premium-class Coupe by taking performance and efficiency to new heights and, for the first time, offering the additional benefits of xDrive.
The latest generation of the most powerful diesel engine boasts displacement of 3.0 litres, a low-weight all-aluminium crankcase and the latest development of BMW TwinPower Turbo technology. This package of technology comprises multi-stage turbocharging and common-rail direct injection whose piezo injectors work with maximum pressure of 2,000 bar. The car’s two-stage turbocharging generates instantaneous and forceful power delivery, while the injection system sprays the fuel into the cylinders in precisely measured quantities to ensure clean and efficient combustion.
Two-stage turbocharging with optimised efficiency.
The latest multi-stage turbocharging technology responds more precisely than ever to the demands of different driving situations. At low revs a smaller turbocharger is activated, its low moment of inertia allowing it to go to work extremely rapidly. The compressed air from this small charger is sent directly to the combustion chambers via a bypass line. As the air no longer flows through the large charger, loss-free development of charge pressure is assured. Only when the driver asks for more power do the electronics prompt the bypass unit to bring the larger turbo into play. Added to which, variable turbine geometry for the smaller of the two turbos optimises the effectiveness of the turbocharging system in responding to the power requirement at any one time.
The result is an ultra-fast response to every movement of the accelerator. The engine delivers its peak torque of 630 Newton metres (465 lb-ft) as low down as1,500 – 2,500 rpm, with maximum output generated at 4,400 rpm. Powerful acceleration from a standstill and dynamic mid-range sprints are therefore dispatched with equal ease. The eight-speed Sports automatic gearbox is tuned precisely to the performance characteristics of the engine, and so allows the driver to exploit its impressive torque – maintained across a high rev band – to the full, for a sporty yet smooth driving experience. By contrast, in ECO PRO mode (likewise standard) the power reserves of the sporty diesel engine play a prominent role in ensuring a relaxed and extremely efficient driving style at low engine speeds.
BMW EfficientDynamics package of technology and Driving Experience Control come as standard.
ECO PRO mode, which is activated via the standard-fitted Driving Experience Control switch, carries out adjustments to the engine management, accelerator mapping and the shift characteristics of the automatic transmission. In addition, the output of electrically operated functions such as the climate control system, as well as the seat and exterior mirror heating are carefully regulated to ensure extremely efficient energy management. Special displays inform the driver of the extra range, in kilometres, achieved as a result. The BMW EfficientDynamics technologies fitted as standard on board the BMW 640d xDrive Coupe also include Brake Energy Regeneration, the Auto Start-Stop function, need-based operation of ancillary units and active air flap control.
The Driving Experience Control switch can also be used to call up SPORT, SPORT+ and COMFORT modes, and – if the optional Dynamic Damper Control or Adaptive Drive are selected – COMFORT+. As well as the accelerator progression, engine responses, power steering characteristics, intervention thresholds of the DSC stability control system and shift dynamics of the automatic transmission, this also allows the driver to adjust the damper settings and anti-roll control. Whichever mode he chooses, the driver is activating a pre-configured and coherent overall set-up which includes reproduction of the engine sound. Here, a sound module is used to enhance the engine’s natural acoustic components to suit the driving situation and the Driving Experience Control mode selected, and this soundtrack is then transferred into the interior. The system’s digital signal processing technology exchanges data directly with the engine management and adjusts its output to the engine’s revs, the amount of torque being produced and the car’s speed over the road. This gives the driver an impressively accurate impression of how hard the engine is currently working and of the power being unleashed, and provides an even clearer window into the car’s responses on the road.
Intelligent all-wheel drive raises driving pleasure another notch.
The introduction of the BMW xDrive all-wheel-drive system into the
BMW 6 Series range adds another alluring dimension to the
driving experience on board a top-class premium coupe.
The BMW
640d xDrive Coupe showcases the latest incarnation of the intelligent
all-wheel-drive system. In addition to the variable transfer of power
to the front and rear wheels, this technology also includes
Performance Control, which divides drive between the right and
left-hand rear wheels to suit the situation at hand.
In contrast to conventional all-wheel-drive systems, the
electronically controlled BMW xDrive is set up not only to optimise
traction on low-grip surfaces, but also to enhance dynamic performance
through corners. The link-up of the all-wheel-drive system with the
DSC (Dynamic Stability Control) function within the
ICM
(Integrated Chassis Management) system enables all situations on the
road to be identified and evaluated to allow the necessary control
interventions to be made at an early stage. These can be carried out
by xDrive either on its own or in combination with Dynamic Stability
Control or Performance Control. The power is distributed quickly and
with great precision to where it is needed, ensuring that the driver
enjoys the handling characteristics expected of a BMW – even
under extremely dynamic cornering.
The xDrive system has been specially tuned for service in the BMW 6 Series, taking into account the car’s specific properties and characteristics. This bespoke set-up is underpinned by the principle of blending the traditional rear-wheel-drive qualities of BMW cars harmoniously with the benefits of distributing power between all four wheels. As with every all-wheel-drive BMW, 60 per cent of the engine’s power is sent to the rear axle in normal conditions and 40 per cent to the front wheels. This torque split can be adjusted in an instant to suit changing conditions.
Linking up to allow proactive analysis and precise interventions.
Identifying the risk of traction loss at a very early stage allows
wheel spin to be prevented at one or more wheels by varying power
distribution. xDrive can therefore be described as an
“intelligent” all-wheel-drive system.
This proactive
analysis of the driving situation takes into account the data from the
engine management system and information on accelerator position,
steering angle, wheel speeds and lateral acceleration stored in the
ICM system. Based on this extensive information, xDrive is able to
finely control the distribution of power between the front and rear
wheels to ensure that engine output is fully utilised at all times.
This allows xDrive to nip oversteer or understeer in the bud –
unlike conventional all-wheel-drive systems, which only react when at
least one wheel is already spinning. If the car is threatening to
understeer, a greater proportion of drive power is immediately sent to
the rear wheels.This makes for sharper turn-in on the entry to a
corner; in other words, xDrive improves stability before the driver is
even aware of the need. Similarly, the system’s proactive
capabilities allow it to correct oversteer tendencies at the earliest
possible stage by directing surplus power to the front wheels. That
means the benefits of all-wheel drive can be enlisted even before
traction loss actually occurs.
Intelligently varied power distribution also has benefits for ride comfort; due to the stabilising effect of xDrive, DSC now only needs to intervene in extreme situations. Only when optimal drive power distribution alone is insufficient to keep the vehicle on track does DSC intervene by reducing engine power and selectively braking individual wheels.
Electronic control enables extremely rapid reactions.
The xDrive system’s electronic control system allows the power split between the front and rear wheels to be altered almost instantly to suit changing driving conditions. It does this by adjusting the multi-plate clutch in the central transfer case, using a stepper motor. The higher the pressure on the clutch plates, the more power is transferred to the front wheels via a gear system. Conversely, when the clutch is completely open, all power goes to the rear wheels. The electronic control system is capable of varying the torque distribution in record-quick time: it takes just 100 milliseconds to fully open or fully close the clutch.
Performance Control improves these driving dynamics even further. Working with the xDrive control function, this electronic system uses precisely controlled braking and variable torque distribution to counteract the onset of understeer on low-traction surfaces and under particularly dynamic cornering, thereby improving agility. As soon as understeer is detected, the integrated electronic control functions of xDrive and DSC selectively brake the rear wheel on the inside of the corner. The resultant loss of propulsion is compensated for by an increase in drive power.
BMW xDrive now also destined for success in the BMW 6 Series.
BMW has offered its customers all-wheel-drive vehicles for more than
25 years. From the outset, BMW used the transfer of power to
both axles not only to optimise traction on loose surfaces and in
adverse weather conditions, but also to enhance dynamic performance
through corners. Over the years,
all-wheel drive has developed
from an option initially limited to selected models to a growth driver
for the ongoing expansion of the model range.
The worldwide success of xDrive has also been aided by the introduction of the BMW X models. With the BMW X5, BMW X6, BMW X3 and BMW X1, the range now includes four models which set the benchmark in their segments in terms of agility and driving pleasure. In these models, as elsewhere in the BMW range, the all-wheel-drive system not only gives drivers a traction and stability advantage, but also plays a key role in delivering stand-out dynamic performance. Alongside the triumphant progress of the BMW X models, the number of all-wheel-drive variants in other model series has also grown consistently. Today, xDrive models can be found in the BMW 3 Series, BMW 5 Series, BMW 7 Series and now, for the first time, the BMW 6 Series range.
The new BMW 640d xDrive Coupe injects an extra dose of variety into
the
BMW 6 Series, and the intelligent all-wheel-drive system is
also fitted in the
BMW 650i xDrive Coupe. In this model, xDrive
divides the power generated by a V8 engine with BMW TwinPower Turbo
technology between the front and rear wheels. The power unit
underneath the bonnet of the BMW 650i xDrive Coupe develops maximum
output of 300 kW/407 hp and peak torque of 600 Newton
metres (443 lb-ft), and again links up with the eight-speed Sports
automatic gearbox. With the added benefits of xDrive on board, the car
can sprint from 0 to 100 km/h (62 mph) in 4.8 seconds.
BMW 6 Series Coupe offers greater variety.
With three engine variants (bearing the BMW 640i, BMW 650i and
BMW 640d badges), a choice between BMW’s traditional
rear-wheel drive and intelligent all-wheel-drive technology,
state-of-the-art chassis technology and an array of innovative and
– in some cases – unique equipment features, BMW brings an
exclusive product package to the premium luxury-class coupe table.
The new BMW 6 Series Coupe can also be equipped with a specially developed M Sport package. The aerodynamic, exterior and interior components designed in familiar M style clearly showcase the sports car character of the 6 Series Coupe. Equipment includes an M aerodynamics package with bespoke body components for the front end, side sills and rear apron, exhaust tailpipe embellishers in Chrome Dark, LED front fog lamps and 19-inch light-alloy wheels in M double-spoke design. 20-inch light-alloy wheels in M double-spoke design can also be ordered as an option. Inside, features such as M-specific Alcantara/leather sports seats in Anthracite with Blue contrast stitching, an M leather steering wheel with multifunction buttons and gearshift paddles, and Aluminium Hexagon interior trim strips all play their part in creating a full-blooded driving experience. The M Sport package also includes door sills bearing the M logo, as well as an M driver’s footrest.
The BMW 6 Series Coupe offers seating for four immersed in a luxurious ambience, while its 460-litre boot can accommodate three 46-inch golfbags or two medium-sized hard-shell suitcases plus a flight case. The comfort-enhancing equipment fitted as standard in the new BMW 6 Series Coupe includes 2-zone automatic climate control, a multifunction steering wheel, electric steering column adjustment, electrically adjustable and heated exterior mirrors, Cruise Control with braking function, a rain sensor with automatic headlight range control, a HiFi audio system and the control system iDrive with a freestanding Control Display in flatscreen design. Among the highlights on the options list are Adaptive LED Headlights and the Bang & Olufsen High End Surround Sound System.
A rich variety of driver assistance systems and mobility services
from
BMW ConnectedDrive also help to give the new BMW 6 Series
Coupe its innovative character. Enhancing convenience during a
journey, for example, are services such as a personal assistant who is
at your service around the clock and searches for addresses, inputting
them as destinations directly into the navigation system. The
Real-Time Traffic Information function, meanwhile, transfers
extraordinarily precise data and diversion recommendations to the
navigation system.
Other supportive functions include Active
Cruise Control with Stop & Go function, Speed Limit Info, a
rear-view camera, Surround View and BMW Parking Assistant. The scope
of in-car infotainment, meanwhile, enters a new dimension: the Apps
option and BMW Connected application allows Apple iPhone owners to use
Facebook, Twitter and the web radio function inside their
BMW 6
Series Coupe. And the office functions enable calendar entries, for
example, or e-mails on a smartphone to be shown in the vehicle display
and read out to the driver. ConnectedDrive features also help to
improve safety. The new-generation BMW Head-Up Display offers
optimised display quality, with a full spectrum of colours now
available for the graphics, allowing extremely realistic-looking
symbols to be projected onto the windscreen. Other functions include
Advanced Emergency Call with automatic position finding and accident
severity detection, BMW Night Vision with pedestrian recognition, the
Lane Change Warning System and the Lane Departure Warning System.
