A simple letter andnumbercombinationwhich
has become synonymous with an extremely
powerful and dynamic performance car.
The M3 is now in its fourth generation with a
history of success in the world of motor sport,
winning races across the globe since its
beginning back in 1985. Not only has the race
version of the M3 gained a successful motor
sports heritage, its on road credentials live up
to the expectations and demands of today’s
M3 drivers. The E92 M3 will be launched in
the middle of 2007.
This preciselybalanced sportscar will set new
benchmarks in driving dynamics for sport
coupes. As with its predecessor the focus has
been on optimizing the power to weight ratio
whilst maintaining the high engine speed
concept. This combination ensures that both
power and driving agility are exceptional,
placing the M3 in an even higher level of sport
car competition.

Engine and technical data
V8 with high engine speed concept
It will be the first time that a V8 engine has
been fitted in a series production M3. The
main concept behind this high-revving, high
performance enginewith a sportysound is the
extremely light, rigid and robust construction
which is capable of reaching extreme engine
speeds of up to 8,400 rpm. The engine
achieves an impressive 420 hp (over 100 hp
per litre).
The S65B40 is derived from its big brother,
the S85B50. The main changes can be seen
11 - S65B40 front view
in the engine oil system, VANOS valve gear
system and air intake system. Special
consideration has also been given to engine
weight optimization.
The engine with all its assemblies is built inthe
special engine production area of the Munich
BMW plant.
One standard engine is used throughout the
world and adapted to suit specific market
requirements.
10

A new dimension to the high engine
speed concept
The M engineers consider the high engine
speed concept to be the most intelligent
strategy of obtainingthe maximum thrustfrom
a vehicle.
For example, in a modern formula 1 engine,
the crankshaft works at up to 19,000 rpm
(resulting in piston speeds of over 25 metres
per second).
The actual thrust at the driven wheels is the
decisive factor for car acceleration. This thrust
is achieved by the engine speed, the torque
and the short gear ratio.
12 - Formula 1 example
This concept has beenadopted forvehicles in
the 'M' range from motor sport. The fully
variable M limited-slip differential means that
the thrust is optimally distributed to the live
axle.
Furthermore, the S65B40 also includes the
established M-specific features such as
double VANOS, individual throttle butterflies
and high-performance engine electronics
(MSS60 control unit).
14 - S65B40 Notional view without the intake manifold
Technical workarounds by increasing the
cylinder capacity or boosting become
superfluous, thus avoiding the increased
engine weight and consumption often
associated with these methods.
The high engine speed concept helps to
achieve dynamically agile handling and the
maximum in sports driving performance
characteristics.
A maximum torque of 400 Newton meters at
3,900 rpm is reached. Approx. 85 percent
(340 Nm) can be utilized beyond the
enormous engine speed range of 6,500 rpm.
The S65B40 attains 8,400 rpm, and therefore
a value that was previously only reserved for
racing car engines or exotic custom vehicles.
3 For safety reasons, due to the engine
dynamics when the vehicle is stationary (i.e.
without a road-speed signal), it is already
down-controlled at 7,000 rpm to prevent the
engine speed from increasing into an
impermissible range. 1

The MDrive option
The MDrive menu known from the M5/M6 is
now also available as an option (SA 2MD) in
the M3.
Starting from the iDrive main menu, the
MDrive menu can be called up by pressing on
the iDrive controller and selecting M settings.
The iDrive controller can be used to configure
the different MDrive settings ready to be
called up.
The overall setting is called up/activated by
pressing on the M button on the steering
wheel. Pressing the M button again or
restarting the vehicle deactivates the settings.
The settingscan, of course, be retrievedagain
using the M button.
The following is a list of menu items with
selection options that are currently
available in the MDrive menu:
• M Engine Dynamics Control (Power)
– "Unchanged"
– "Normal"
– "Sport"
– "Sport Plus"
• DSC
– "Unchanged"
– "OFF"
– "ON"
– "M Dynamic mode"
• Servotronic
– "Normal"
– "Sport"
• EDC-K (only if fitted)
– "Unchanged"
– "Comfort"
– "Normal"
– "Sport".
By selecting "Unchanged", whentheMbutton
is pressed (i.e. the settings in the MDrive
menu are called up), the current settings of
this system are retained.
Example:
The driver has deactivated the Dynamic
Stability Control function using the DSC
button.
MDrive setting: M Engine dynamics control
"Sport Plus"; DSC "Unchanged"; Servotronic
"Sport".
The driver presses the M button on the
steering wheel to call up the M settings.
Only the "Sport Plus" and Servotronic "Sport"
settings for M engine dynamics control are
activated.
DSC remains deactivated.

Information on the menu items
M Engine Dynamics Control (Power)
Apart from"Unchanged", three enginecontrol
programs are available;
"Normal", "Sport" and "Sport Plus".
The options determine how spontaneously
the engine responds to actuation of the
accelerator pedal.
The maximum engine power is not changed.
Using the power button in the centre console,
the driver can only choose between "Normal"
and "Sport".
"Sport Plus" is only available in the MDrive
menu.

with iDrive controller
DSC
Apart from the "Unchanged" setting, in the
DSC submenu, the options "OFF" "ON" and
"M Dynamic mode" can be selected.
If "M DynamicMode" is selected, theDynamic
Stability Control (DSC) permits higher slip
values at the wheels.
The system does not activate the stabilizing
function until very close to the handling limit
range, when itinfluences engine outputand/or
actively engages the brakes.
In "OFF" mode, an experienced sports car
driver can also completelydeactivate the DCS
function.
Using the DSC button in the centre console,
the driver can switch between "OFF" and
"ON" or if "M Dynamic Mode" is active,
between "M Dynamic Mode" and "OFF".
"M Dynamic Mode" is only available in the
MDrive menu.
EDC-K
If option 223 continuous Electronic Damper
Control is fitted together with MDrive, in
addition to "Unchanged", three EDC
programs can be selected in the MDrive
menu: "Comfort", "Normal" and "Sport".
The driver can use the EDC button in the
centre console toswitchsequentially between
the three programs.

Servotronic
The settings that can be selected for the
Servotronic steering function are "Normal"
and "Sport". Depending on the selection, the
appropriate characteristic curve for powerassisted steering is active.
This selection option is only available in the
MDrive menu. Without MDrive, the customer
has nooption, and a fixed programmedspeeddependent characteristic curve is used.
"Key-dependent settings" menu
Under "M settings", the "Key-dependent
settings" menu is also available as well as the
MDrive menu.
This allows key-specific settings for certain
MDrive menu items.
M engine dynamics control and EDC settings
are currently possible, which are assigned to
the specific key used during the configuration
(configuration => ZV closing action =>
memorizing).
Under the M engine dynamics control menu
item, "Normal" or "Sport" can be selected.
In the EDC menu item, the options "Comfort",
"Normal" or "Sport" can be selected.
