Vehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your vehicle, e. g., due
to the selected options or country versions.
This also applies to safety-related functions
and systems. When using these functions and
systems, the applicable country provisions
must be observed.
High-performance engine
General information
With a displacement of 3 liters, the high-per‐
formance engine generates a maximum power
of 425 hp, with Competition Package 444 hp
and a maximum torque of 406 lb ft/550 Nm.
With its spontaneous response behavior, a
speed range of wide utility results. The maxi‐
mum engine speed is 7,600 rpm and is elec‐
tronically controlled. Because of the high en‐
gine dynamics, the maximum engine speed
with the vehicle stationary is reduced.
Warm-up
During the engine warm-up phase, the high-
performance engine has a somewhat rougher
running behavior because of the emission con‐
trols.
When the engine is cold, the exhaust system
has a slightly metallic undertone due to the na‐
ture of the system.
For more information about the warm-up pro‐
cedure: Engine speed, refer to page 85, and
engine oil temperature, refer to page 85.

Compound brake
The high-performance braking system has
perforated compound brake discs.
Because of particular structural characteristics,
there may be operation-related noises during
braking. However, this has no effect on per‐
formance, operational reliability and reliability
of the brake.
Correct braking
To keep the brake system in optimum condi‐
tion, it is expedient to apply them at regular in‐
tervals corresponding to the vehicle character.
M carbon ceramic brake
The high-performance braking system has
perforated carbon ceramic brake discs.
Due to properties of the materials used, brak‐
ing may be associated with louder function
noises, particularly in wet conditions, just be‐
fore the vehicle comes to a stop. However, this
has no effect on the performance, operational
reliability and durability of the brake.
The effects of moisture and road salt, from us‐
ing a carwash or dew formation overnight, e.g.,
may render the braking effect comparable to
that of a conventional braking system. This
may be perceived as reduced braking effect
and can be compensated for, if needed, by
pressing the brake pedal harder.
Before washing the vehicle in an automatic
carwash or wash tunnel, clean the brake discs
and brake calipers with a steam jet or high-
pressure washer as well, to prevent encrusta‐
tions and dirt buildups, caused by salt crystals,
e.g., if the vehicle is immobile afterwards. The
cleaning effect of automatic carwashes or
wash tunnels is usually not adequate for this in
the area around the wheels.
