Vehicle features and
options
This chapter describes all standard, country-spe‐
cific and optional features offered with the series.
It also describes features and functions 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 sys‐
tems. When using these functions and systems,
the applicable laws and regulations must be ob‐
served.
High-performance engine
General information
With a displacement of 3 liters, the high-perform‐
ance engine generates a maximum power of
473 hp, as Competition model 503 hp, and a
maximum torque of 406 lb ft/550 Nm, as Com‐
petition model 479 lb ft/650 Nm. With its sponta‐
neous response behavior, a speed range of wide
utility results. The maximum RPM is 7,200 rpm
and is electronically controlled. Because of the
high engine dynamics, the maximum RPM with
the vehicle stationary is reduced.
Warm-up
During the warm-up phase, the high-perform‐
ance engine has in increased idle speed to bring
the emission control system to operating tem‐
perature.

Tachometer, refer to page 159.
Engine oil temperature, refer to page 159.
Compound brake
General information
The high-performance brake system has perfo‐
rated compound brake discs.
Due to the specific layout, temporary functional
noise may occur after an extended minor brake
load.
The functional noises have no effect on the per‐
formance, operational reliability, and durability of
the brake.
Correct braking
To prevent functional noises, it is expedient to
apply the brakes hard a few times in regular in‐
tervals. Ensure that the traffic situation permits
the brake operations.
With moisture on the brake discs, the brake sys‐
tem may be operated dry to prevent noise.
M carbon ceramic brake
General information
The high-performance brake system has perfo‐
rated carbon ceramic brake discs.
Due to properties of the materials used, braking
may be associated with louder function noises,
e.g., in the event of an extended minor brake load
or in wet conditions, just before the vehicle
comes to a stop.
The functional noises have no effect on the per‐
formance, operational reliability, and durability of
the brake.
The effects of moisture and road salt from using
a car wash, dew formation overnight, driving in
rain, etc., may render the braking effect compa‐
rable to that of a conventional brake system. If
necessary, this reduced braking effect can be
