Vehicle equipment
This chapter describes all standard, national
and special equipment available for the model
series. Therefore equipment which is not in‐
stalled in your vehicle, for example on account
of the selected optional equipment or the
country specification, may also be described
here. This also applies to safety-relevant func‐
tions and systems. Comply with the relevant
laws and regulations when using the corre‐
sponding functions and systems.
High performance engine
General
The high power engine generates a maximum
power of 317 kW, with Competition package
331 kW and a maximum torque of 550 Nm
from 3 litres of capacity.
The maximum power for the M4 CS is 338 kW
and the maximum torque 600 Nm.
The spontaneous responsiveness of the high-
performance engine produces a very broad
usable engine speed range. The maximum en‐
gine speed is electronically regulated at
7600 rpm. Due to the powerful engine dynam‐
ics, the maximum engine speed is limited when
the vehicle is stationary.
Driving hot
During the engine warm-up phase, the high
performance engine runs slightly more roughly
due to the emission control.
When the engine is cold, the exhaust has a
slightly metallic undertone, depending on the
system.
Other information for hot driving: engine speed
counter, see page 105, and engine oil temper‐
ature, see page 106.

M compound brakes
The high performance brake system has venti‐
lated compound brake discs.
Depending on design requirements, function
noises may occur when braking. The functional
noises have no effect on the efficiency, opera‐
tional safety and endurance of the brake.
Braking correctly
To keep the brake system in optimum condi‐
tion, it is desirable to load them at regular inter‐
vals depending on the nature of the vehicle.
M Carbon ceramic brakes
The high performance brake system has venti‐
lated carbon-ceramic brake discs.
Depending on the material-specific properties,
there can be increased functional noises when
braking, particularly when it is wet, shortly be‐
fore the vehicle comes to a stop. Increased
functional noises have no effect on the effi‐
ciency, operational safety and endurance of
the brake.
Due to the effect of wetness and salt spray, for
example, after using a car wash, condensation
overnight, driving in rain etc., the braking effect
may correspond to a conventional braking sys‐
tem. The braking effect may be perceived to
be reduced and can be compensated for by
greater pedal pressure, as needed.
First clean brake discs and callipers with a
steam cleaner or high-pressure cleaner before
washing the vehicle in an automatic washing
bay or car wash. This prevents salt crystals,
for example, from causing crusty deposits and
build-up to form if the vehicle then remains
stationary for a period of time. The cleaning ef‐
fect of automatic car washes generally not suf‐
ficient for this in the wheel area.
