BMW M4 TechnologyVehicle equipment
This chapter describes all standard, national
and special equipment provided in the model
series. Equipment not available in the vehicle is
therefore also described, for example the se‐
lected special equipment or national version.
This also applies to safety-relevant functions
and systems. Comply with the relevant na‐
tional regulations when using the correspond‐
ing functions and systems.
High performance engine The high performance engine generates a
maximum power of 317 kW and a maximum
torque of 550 Nm from 3 litres of capacity.
With its spontaneous responsiveness, a very
broad usable engine speed range is produced.
The maximum engine speed is electronically regulated at 7,600 rpm. Due to the powerful
engine dynamics, 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 84, and engine oil tempera‐
ture, see page 84.
M compound brakes The high performance brake system has venti‐
lated compound brake discs.
Depending on design requirements, function
noises may occur when braking. However, thishas no effect on the performance, operational
safety and stability of the brakes.
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 braking system has per‐
forated carbon ceramic brake disks and is de‐
signed for racetrack operation.
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. This has no
effect on performance, operational safety and
endurance of the brakes.
Due to the effect of wet and salt spray, for ex‐
ample, after using a car wash, condensation
overnight etc., the braking effect may corre‐
spond to a conventional braking system. This
can be detected as reduced braking effect and
compensated for by higher pedal pressure, as
needed.
Clean brake discs and brake calliper before
washing in an automatic car wash with a steam
sprayer or high pressure cleaner to avoid en‐
crustations and caking, for example, due to salt
crystals with a related stationary period. The cleaning effect of automatic car washes gener‐
ally not sufficient for this in the wheel area.
Also follow the information on this under vehi‐
cle washing, see page 208, and safe braking,
