THE NEXT CHAPTER IN THE STORIED HISTORY OF BMW M
All-New BMW X6 M and BMW X5 M Make World Debuts in 2009
Woodcliff Lake, NJ ? April 5, 2009? The modern, sustainable legacy of
BMW M GmbH began in 1985 when engineers placed the snarling, race-bred inline-
6 engine from the M1 supercar into the production BMW 5 Series sedan, reworked
the suspension and brakes, and created the first M5. Through this industry-first
combination of attributes, the M5 redefined the capabilities of a sedan with levels
of power, precision, balance, and linear control never before imaginable. Since
then, finding new ways to expand the boundaries of what is possible with existing
BMW models has been the singular purpose of the craftsmen at BMW M. Now the
BMW X5 M and the BMW X6 M are the first all-wheel-drive models to offer the
remarkable performance, dynamic driving experience, athletic design, and
premium quality of a BMW M product.
Both models are powered by a newly-developed 4.4-liter V8 M engine delivering
555 hp at 6,000 rpm and 500 lb-ft of torque from 1500 to 5,650 rpm. This new
M engine is the world?s first with a pulse-tuned exhaust manifold encompassing
both rows of cylinders combined with high-performance twin-scroll twin turbo
technology.
For the X5 M and X6 M, engineers at BMW M pushed the capabilities of BMW?s
intelligent xDrive all-wheel-drive system and the Dynamic Performance Control
system to manage the power and performance potential of these two new
vehicles. The special M suspension includes Adaptive Drive and newly-developed
Servotronic power steering. These features combine to push the limits of what
was previously possible with a sports-oriented vehicle, and guarantee driving
behavior characteristic of a BMW M product: incredible stability and precisely
controlled steering qualities abound throughout the performance envelope.
The BMW X5 M and BMW X6 M set new standards of acceleration, lateral grip,
steering response, balance, and stopping power among high-performance activity
vehicles. Both models accelerate to 60 mph from a standstill in 4.5 seconds and
feature impressive delivery of power from the V8 twin-turbo engine which
provides maximum torque of 500 lb-ft from 1,500 and 5,650 rpm. From a
handling standpoint, both vehicles are notable for superb balance through careful
tuning of xDrive, Dynamic Performance Control, and Dynamic Stability Control
with M Dynamic Mode for linear buildup of cornering forces. These capabilities
place the performance of the X5 M and X6 M on par with the performance of
other recent BMW M vehicles.
The athletic character and amazing performance abilities of the BMW X5 M and X6
M result from levels of development never before applied to this type of vehicle.
As it did when creating the original M5, BMW M has once again shown that
applying new technologies and innovations to a solid BMW production vehicle type
will produce startling performance and an exhilarating drive. Both of these new
models offer capabilities and dynamic driving experiences which are quite unique,
and promise to provide thrills from everyday traffic to the race track.
The first modern turbocharged M engine: twin scroll twin turbo
technology with a patented exhaust manifold.
Using BMW?s innovative, 4.4L reverse-flow V8 engine with High Precision Direct
Injection and twin turbochargers as a basis, the new M engine introduces twinscroll
twin turbochargers and patented exhaust manifold technologies to achieve
outstanding thrust and pulling force, while preserving the most compact
dimensions possible. Two low-mass twin-scroll turbochargers are positioned
together with the catalytic converters in the ?V? section between the two banks
of cylinders. By reversing the flow of gases through the engine from traditional
arrangements, the intake and exhaust ducts are shortened and widened. The
result is that pressure losses on the exhaust side are minimized.
The goals: virtually eliminate turbocharger lag while maximizing combustion
efficiency and power output. Tremendous power and performance are delivered
by the engine in the BMW X5 M and BMW X6 M through a new design and
construction principle. The new M V8 engine with twin-scroll twin turbo
technology uses a single exhaust manifold with tuned-length runners,
incorporating both cylinder banks and connecting cylinders in carefully-selected
pairs. This configuration, patented by BMW M and known as Cylinder-bank
Comprehensive Manifold (CCM), offers lightning-quick response, a linear build-up
of engine power, and a broad, consistent torque curve by feeding each of the
twin turbochargers with a ?charge pulse? at approximately every 90 degrees of
crankshaft rotation, rather than the more traditional ?irregular schedule? of
charging.
The managed flow of exhaust gas provided by the CCM ensures high-velocity flow
of combustion gases. The appropriate separation of exhaust gas flow from
different cylinders is maintained until the gas reaches the turbine wheel, spooling
the two twin-scroll turbochargers without back-pressure. With maximum boost
pressure of 1.5 bar (21 psi), the use of twin-scroll twin turbo technology and the
CCM exhaust manifold allows complete exploitation of the benefits of
turbocharging.
Immediate response and remarkable thrust characterize the new V8 twinturbocharged
engine from BMW M GmbH. The impressive onset of power is
accompanied by unique, engaging engine sounds that accentuate the quickrevving
characteristics with the dynamic acoustic effect typical of a BMW M
product. The sounds are always civilized, but transform from relatively calm to
extraordinarily intense as the boost and revs build from idle. Reflecting the
tremendous power of the engine, the turbocharged M V8 is equipped with an
advanced cooling system developed specifically for the two new models. One
notable feature in this context is the presence of two high-capacity water-to-air
intercoolers which consistently optimize performance under the most demanding
driving conditions. An aluminum oil sump exclusive to BMW M with a special finned
surface guarantees optimum cooling at all times even under an extremely
demanding style of driving.
The turbocharged M V8 engine develops its outstanding power with remarkable
efficiency. In addition to BMW?s High Precision Direct Injection, both the BMW X5
M and the BMW X6 M are equipped with a range of technologies from BMW?s
EfficientDynamics engineering strategy. These include on-demand control of the
electric fuel pump, an on-demand compressor for the air conditioner, and a flowcontrolled
supply of hydraulic fluid to the Active Roll Stabilization system. By
operating these features specifically on demand, energy waste is minimized. The
engine fulfills the requirements of the US LEV II standard as well as the EU5
requirements in Europe.
M Sports Automatic and M shift paddles on the steering wheel.
Featured for the first time on a BMW M model, the 6-speed M Sports Automatic
transmission enhances the high-performance character of the BMW X5 M and the
BMW X6 M through its instantaneous response, direct connection to the engine,
and a high degree of shifting comfort. The new M Sports Automatic is
commanded by an electronic selector on the center console and offers the driver
not only the Drive mode, but also Sport and M Manual modes for absolute control
of gear selection.
Aluminum pull-style paddles on the steering wheel exclusive to BMW M allow
manual shifting (Right for upshifts, Left for downshifts). Upshifts occur
significantly quicker than in the past thanks to new technology that reduces
torque in the transmission through momentary deactivation of individual cylinders.
This significantly enhances the athletic character of the vehicle. In the M Manual
mode, each chosen gear is held up to redline in order to give the driver perfect
throttle-steering control of the vehicle under the most demanding driving
conditions. The transmission does not upshift or downshift automatically in this
mode. A further option in the M Manual mode is to activate the Launch Control
feature, which enables the driver to accelerate from a standstill with maximum
performance. To activate Launch Control, the driver stops the vehicle, moves the
gear selector into the M/S position and activates the Sports Power mode, as well
as the M Dynamic mode, or respectively, the DSC-Off mode. Then, with the
transmission in stage M1, the driver presses down the brake pedal and moves the
accelerator to at least 60% throttle, setting Launch Control to standby. Standby
status is confirmed by ?starter?s flag? symbol in the instrument cluster. As soon
as the driver releases the brake pedal, the vehicle will accelerate with full power in
?genuine racing style.? In the process, the M Sports Automatic transmission
automatically upshifts at the ideal points, with the fastest possible shifts and
optimum wheelspin control. The driver may terminate the Launch Control process
at any time by reducing the throttle position.
BMW xDrive and Dynamic Performance Control with a special M setup
for optimum dynamics.
The outstanding success of BMW?s intelligent xDrive all-wheel-drive technology is
based on quick, electronically-controlled power distribution to the front and rear
axles. When combined with the superb, near 50-50 static weight distribution of
any BMW, xDrive can prevent the tendency for the vehicle to oversteer and
understeer as long as possible, reducing the need for Dynamic Stability Control
(DSC) to provide electronic assistance.
BMW?s Dynamic Performance Control was presented for the first time in the BMW
X6 and is now featured in the BMW X5 M and the BMW X6 M. Put succinctly,
Dynamic Performance Control enhances driving stability in demanding situations
and is thus perfectly suited to a powerful M vehicle. Vectoring of torque between
the right and left rear wheels (both on throttle and off) significantly improves
steering precision and tracking stability at all speeds, with DSC being required to
stabilize the vehicle only under extreme lateral acceleration. Ultimately this offers
the driver an unparalleled standard of performance, agility, balance, and traction,
and re-establishes the benchmarks in drivetrain and suspension technology for all
types of performance-oriented vehicles.
In the BMW X5 M and BMW X6 M the potentials of both xDrive and Dynamic
Performance Control are maximized by BMW M, with the driver able to activate
the M Dynamic Mode (MDM) with the DSC button on the center console or the
steering wheel-mounted M Button. This mode raises DSC thresholds of
intervention and ensures throttle-steering behavior typical of BMW M by shifting
the xDrive bias more to the rear and involving the Dynamic Performance Control in
the process. A pictogram in the Control Display in the instrument cluster allows
the driver to monitor the activity of Dynamic Performance Control and xDrive
through a clear visual depiction, which shows the driver how much power is being
distributed to each wheel.
As a result, M Dynamic Mode allows maximum speeds in bends and on winding
roads with the DSC system intervening only when the vehicle reaches the
absolute physical limits of grip. Even under maximum load in the apex of a bend,
the vehicle follows steering inputs with tremendous precision, giving the driver
very high speeds when exiting a turn in the interest of optimum performance.
Last but not least, DSC may be completely deactivated by experienced drivers at
the touch of a button.
Beyond the stabilizing effects of Dynamic Stability Control provided by individual
brake activation and engine power reduction under extreme conditions, DSC in the
BMW X5 M and BMW X6 M includes a wide range of additional features tuned to
BMW M standards to promote safe and exciting driving. These include ABS antilock
brakes, Trailer Stability Control, Hill Descent Control, Dynamic Brake Control
which maximizes brake force when required, Cornering Brake Control for advanced
trail-braking, Brake Fade Compensation for extreme driving conditions, automatic
Brake Drying when the windshield wipers are activated, Start-Off Assistant for
driving on steep hills, and a braking function for use by the standard cruise
control.
Both vehicles come with an electrohydraulic parking brake which features the
Autohold (Auto H) function. Auto H is a convenience feature that holds the
vehicle in position as soon as it comes to a stop at an intersection or in stop-andgo
traffic, without requiring the driver to hold constant pressure on the brake
pedal. As soon as the driver touches the accelerator again, the brake is instantly
released.
